Introduction

Calogero (creator of radinserein.fr) suggested we meet to get to know each other better and explain our activities. I accepted and proposed a written interview so that readers of our websites could benefit from our discussion.

The goal was to explain why we build our sites and to share our ambitions.

This very pleasant exchange helped us understand why we created and improved our financial websites.

Otherwise, I promised Calogero that I would suggest we drink a Trappist beer the next time I go to Brussels, because Calogero lives in Belgium 😎.

Here are the questions I asked and here are Cologero's answers:

Note: This interview is the result of a voluntary exchange between two independent websites. Neither party was paid.

Questions at radinserein.fr

1. Background and inspiration

1. What motivated you to create Radin Serein?

The idea came from my daily life.

I'm a father, and when it comes to running a household, planning expenses, and leaving room for projects, budgeting quickly ceases to be a theoretical subject. I was looking for ways to optimize our spending without turning family life into a series of deprivations.

I noticed that there was a lot of advice on the Internet, but it was often scattered, difficult to quantify, or too categorical.

So I started by building my own methods and charts. Radin Serein was born from the desire to make them accessible to other households, with clear explanations and tools that can be adapted to one's own situation.

2. Have you always been passionate about saving, budgeting, and personal finance?

No, it was built up over time.

I've been investing personally for almost ten years, which has taught me to think long-term and to look at the numbers with more perspective. But managing a family budget has given me another, much more concrete dimension.

I haven't suddenly developed a passion for spending as little as possible. What interests me is understanding where money goes, avoiding expenses that don't add much value, and saving money for what really matters.

3. What is Radin Serein's biggest obstacle today?

The main challenge is to build trust and visibility for a still new site in a highly competitive field.

On budget-related topics, simply publishing a lot isn't enough. You have to show that the calculations are understandable, that the assumptions are clear, and that the advice remains cautious.

It's also important to accept that credibility is earned gradually. A useful page can require a lot of work before it's discovered by search engines and readers. My goal, therefore, is to build a sustainable website, not to seek short-term, artificial success.

4. What is your response to the prejudices associated with the word "stingy"?

I chose this word with a touch of self-deprecation.

For me, being "peacefully frugal" doesn't mean refusing all spending or anxiously counting every penny. It means rejecting waste and forced spending so that we can spend more freely on what truly has value in our eyes.

The word "serene" is therefore just as important as the word "stingy".

An economy that damages daily life, relationships, or health is not a good economy. The goal is not to be afraid of spending, but to make more choices.

2. Radin Serein's Philosophy

5. How do you define Radin Serein's philosophy?

The budget should be a decision-making tool, not a punishment.

The approach involves first observing, then understanding, and finally acting on a few truly useful levers. I prefer a modest but sustainable economy to a spectacular method that no one can maintain for more than two weeks.

Radin Serein also relies on transparency.

When a calculation depends on a price, a duration, or an assumption, the reader must be able to see and modify it. When a link is affiliated, this must be clearly indicated. And when an answer depends on individual circumstances, this should be acknowledged rather than offering a universal rule.

6. What differentiates you from other financial websites?

Radin Serein deliberately positions itself upstream of individual financial advice.

I mainly work on everyday budgeting, expenses, groceries, energy costs, and household choices. I don't promise to make you rich, and I don't present budgeting as the only right solution.

The difference I am trying to make lies in the practical tools.

A reader can start with their own figures, use a calculator or a table, see the method, and make their decision. Data entered into the site's tools remains in the browser when it does not need to be transmitted.

7. In one sentence, what do you want to convey through your website?

Better understand where your money goes so you can choose what you really want to do with it.

3. The site and its impact

8. What content is most successful with your audience?

The site is still young, so I prefer not to draw any definitive conclusions after only a few months of hindsight.

Initial feedback, however, clearly highlights the calculators, tables and guides that lead to concrete action.

I think it stems from a simple need: readers don't just want to be told how to manage their money better. They want to know where to start and get a result they can review or compare.

A budgeting tool, a living expenses calculator, or a grocery tracking spreadsheet immediately meets this expectation.

9. Do you have any examples of people who have improved their situation thanks to Radin Serein?

Radin Serein is still recent, so I don't have enough perspective to present quantified results or long-term transformations.

However, initial feedback shows that the tools meet a real need. Several readers told me they appreciated the simplicity of the calculators and spreadsheets, particularly for visualizing their expenses and structuring their budget.

The French Federation of CRÉSUS associations also described my approach as pragmatic and felt that the spreadsheet was consistent with the methodology used in supporting households. This exchange also encouraged me to further develop the concept of disposable income within the tool.

These are still early signs, but they confirm Radin Serein's objective: to transform sometimes abstract notions into concrete tools that everyone can use to better understand their situation and make better decisions.

4. Objectives and the future

10. What are your short-term and long-term goals?

In the short term, I want to consolidate what already exists: improve the calculators and the spreadsheet, enrich the most useful guides, gather feedback and make navigation simpler.

I also want to develop coherent sets of content around the monthly budget, disposable income, fixed costs, groceries and energy.

In the longer term, the ambition is to make Radin Serein a French-language reference for practical budget management.

I want to continue offering a solid free foundation and, when it provides real added value, develop some more advanced tools. Monetization should support the quality of the site, not dictate its recommendations.

11. Are you considering other languages or new features?

Yes, but not at the expense of quality.

My priority remains first and foremost to build a truly useful resource in French. Adaptations for Belgium or Switzerland would make sense, as the general method is transferable, even if the amounts, taxation, health insurance, or consumption habits differ.

My main goal is to develop interactive tools. A community aspect could also be interesting, provided there's enough time to moderate it properly and protect personal data. I prefer to proceed step by step rather than adding a feature simply because it seems modern.

12. How do you see the evolution of consumption and the relationship to money in France? Is Switzerland different?

In France as in Switzerland, many expenses are becoming less visible: subscriptions, automatic payments, purchases in a few clicks and fractional services.

At the same time, housing, energy, food, and healthcare are putting significant pressure on many households. I think that budgeting will become less about restriction and more about autonomy.

However, Switzerland presents major differences. Wages and prices are generally higher, the currency is not the same, and health insurance, taxation, pension schemes, as well as cantonal variations, significantly alter the structure of a budget.

A French method can therefore serve as a starting point for a Swiss reader, but the amounts and benchmarks must be adapted to their reality.

5. Tips and inspiration

13. What is your most valuable piece of advice for getting started without feeling restricted?

Observe for a full month without immediately trying to correct everything.

First, you need to list your income, fixed costs, and regular expenses, then calculate what's actually left available. Next, I recommend choosing one manageable improvement rather than cutting all your discretionary spending at once.

A budget works best when it also allows room for enjoyment and unexpected expenses. If it's structured as a punishment, it will be abandoned. If it helps you make choices, it can become reassuring.

NOTE: We share a similar opinion on this point. I've often said that budget optimization takes time and that it's important to understand our mistakes so we don't repeat them. Noting them down and correcting them gradually is essential.

14. What books, people, or experiences have influenced you?

Radin Serein was not built around any particular author or "guru".

My main influence comes from almost ten years of personal investment, the actual management of a family budget and the observation of daily expenses.

I also rely on official sources when the topic requires it, on modern tools to compare and verify information, and on reader feedback. I prefer to test a method against the figures of a real household rather than repeat a formula simply because it's popular.

NOTE: I tested the calculators on radinserein.fr and I can confirm they are useful for Swiss residents. They are in Euros, but you can use CHF as a reference; the result is the same.

15. Can the site be applied to a Swiss budget?

Yes to the method, but not always to the reference amounts.

The principles remain valid: list the expenses, calculate the annual monthly expenses, calculate the remaining living expenses, compare prices per unit and monitor changes over several weeks.

A Swiss reader can enter their own amounts in Swiss francs into most calculators, as the currency unit does not affect the calculations. However, Radin Serein should not be used as a source of Swiss tax, legal, or pension advice. These topics require local and up-to-date information.

16. How do you analyze the level of financial education in France?

I wouldn't say that nothing exists. France has had a national strategy for economic, budgetary, and financial education since 2016, with the Bank of France as the national operator. So, significant resources are available. The problem, it seems to me, lies more in the gap between the information available and its regular use in everyday life.

Many people only truly discover credit, interest, insurance, taxes, or budgeting when they encounter them. Learning remains uneven depending on family background, educational path, and professional situation. Digital products and scams also evolve rapidly. The challenge, therefore, is to make this education more concrete, more frequent, and accessible at the right time, without it being mistaken for a sales pitch.

17. If you were Minister of Finance, what would be your first three measures to develop financial education?

The first would be a practical and progressive learning experience from middle school to vocational training. Students would work on a real budget, a payslip, a loan contract, insurance, compound interest and common scams, with simulations rather than purely theoretical lessons.

The second would be to strengthen free and neutral public resources, as well as training for teachers, social workers, and associations. Financial literacy resources should never be used as a pretext to sell a product.

The third option would be to offer a budgeting benchmark at major life stages: first job, leaving the family home, birth of a child, job loss, or retirement. This assessment would remain voluntary, confidential, and focused on prevention. These measures would obviously require collaborative work with the Ministry of Education, the Bank of France, and community organizations.

18. If you had to summarize Radin Serein in one sentence?

Radin Serein is about budgeting without the pressure: understanding, choosing and saving without depriving yourself of living.

Questions posed to J. Costa (minimalist frugalist)

1. What event or realization led you to create Minimaliste Frugaliste?

The creation of Minimaliste Frugaliste is the result of a convergence of factors, but two main motivations were decisive.

First of all, the lack of personal financial resources in Switzerland When I started writing and sharing my articles, there were only two websites dedicated to this topic in the country. I saw this as an opportunity to contribute by offering a personal approach to help those who wanted to better manage their finances.

Afterwards, the virtuous effect of writing The more I wrote, the more I learned, and the more I wanted to share. This virtuous circle led me to publish over 140 articles. I love learning, and transforming that learning into accessible content has become a true passion.

How do you distinguish between minimalism, frugality, and simply seeking to save money?

Ironically, these three concepts are complementary, but distinct:

Minimalism : A philosophy of life that consists of focusing on the essentials, in all areas (relationships, work, organization, finances, etc.).
Frugalism A financial approach that aims to spend only on essentials while investing for the future. The goal is to reduce unnecessary expenses, optimize your budget, and maximize investments to achieve financial freedom.
Looking for cost savings A component of frugality, centered on avoiding unnecessary expenses. It is a necessary step, but not sufficient to build financial freedom.

3. Why did you combine these two concepts in the name of your site?

I give equal importance to minimalism and frugality, because these two lifestyles are inseparable in my eyes.

A frugal person without a touch of minimalism will struggle to remain consistent in their choices. Conversely, a minimalist who neglects frugality risks not fully optimizing their resources.

For me, these two approaches reinforce each other. Why separate them?

4. Which habit has had the most significant impact on your own budget or quality of life?

Minimalism has profoundly transformed my consumption habits, particularly thanks to the 15-day rule.

Previously, I would buy first and think later, which led to many unnecessary purchases. Now, before buying anything, I wait 15 days to assess whether the item is truly necessary.

Result: a reduction of approximately 90% of my unnecessary expenses, with a method of disconcerting simplicity.

Don't think that the results are only financial. I've also seen positive changes in my own home. (Fewer unnecessary purchases = more space, a more peaceful interior, and less cleaning time).

The goal is not only financial, but also to get rid of what clutters our daily lives and causes frustration.

5. What prejudice about frugality do you encounter most often, and how do you respond to it?

The most widespread misconception is that frugal or minimalist people spend nothing and live in constant deprivation. Nothing could be further from the truth.

People often imagine me as a frugal person or a minimalist, an extreme penny-pincher, counting every penny, who doesn't enjoy life…

However, I have many examples where I don't experience it that way, for example:

I travel regularly
I own a campervan and I use it very regularly.
I like to invite people over and I gladly offer a beer and a good meal to my loved ones.

On the other hand, I am also vigilant about unnecessary expenses, for example:

I cancel unnecessary subscriptions or insurance policies.
I prefer modest accommodation to a spacious and expensive apartment
I travel to work by scooter (instead of a sports car)
I don't buy rounds of beer for distant acquaintances.

Some may see this as "”to be stingy”"That's their interpretation and that's their judgment.

For me, it's simply a matter of managing my resources responsibly, both financial and relational. And I feel happy living this way. Isn't that the most important thing?

6. Is there a difference between the way the French and the Swiss talk about money and consumption?

Yes, I observe several marked differences:

Everyday Economy The French often seem more economical to me than the Swiss. I regularly hear Swiss people say: «"Well, it's not worth saving 200 CHF a month for that."» A phrase I've never heard in France.
Financial transparency In Switzerland, talking about money remains very taboo. For example, many avoid revealing the price of their rent, for fear of being labeled "rich." In France, the discussion of personal expenses seems more open.
Invest However, the Swiss are generally more open to stock market investments, while the French remain very attached to real estate and less open to the stock market.
Consumption On this point, the two countries are similar: a significant portion of the population consumes excessively. It is precisely to help them that our websites exist.

7. How do you decide whether a purchase is useful, superfluous, or simply a source of legitimate pleasure?

I rely on the 15-day rule (answer to question 4).

Waiting two weeks before buying allows you to distinguish a passing desire from a real need.

Note that this method is not foolproof, but it works in 95% of cases for me.

8. What frugal tip have you tried and then abandoned because it didn't suit you?

By training people in personal finance, I understood one essential thing: Mistakes are formative..

At first, I tried to avoid consumer mistakes at all costs for my clients. Now, I let them make them, because it's by making mistakes that we learn not to repeat them.

In reality, anticipating every mistake is impossible. Leaving room for learning through experience is far more impactful in the long run.

9. What first action would you advise a new household to take?

Create a budget reasonable and track each expense for several months.

Honesty with oneself is key: by analyzing one's mistakes, one learns not to repeat them.
For those who like structured tools, your site (radinserein.fr) offers suitable calculators.

But in my opinion, starting with a simple, regular analysis of your bank statements from your smartphone is already an excellent starting point.

The real danger isn't spending unnecessarily once, because that happens to everyone. The real risk lies in repeated mistakes. Those are the ones that cost dearly in the long run.

Next, it's important to balance income, savings, and expenses. But I'm already working on the second step 😉

10. What would you like Minimaliste Frugaliste to become in the coming years?

Since its creation, my website has been based on four clear objectives:

1) Developing my skills in personal finance.

2) Helping those who wish to optimize their spending and adopt a minimalist lifestyle.

3) Attracting new customers for my services.

4) Use my website to create a business card for professional opportunities that interest me.

Thanks to MinimalisteFrugaliste, I've already had the chance to meet some extraordinary people and participate in some very interesting projects. I hope to continue on this path, further expanding the site's positive impact.

Conclusion

I thank Calogero for this written interview.

It was an aspiring exercise, which not only stimulated my curiosity about radinserein.fr, but also questioned the roots of miniamalistefrugaliste.

I really liked the Radinserein.fr website and I think I'm going to use some of the very practical calculators.

How does this blog live?

Overall, this blog lives from sharing a frugal and/or minimalist lifestyle.

For the sake of transparency towards readers, all the products recommended are intended to make life cheaper and simpler.

Essentially, my only income from this blog comes from the training courses I conduct, promo codes for products I use, and donations readers make in exchange for neutral information.

About me

Faced with not very effective financial education, as was my case before. I actually decided to create this blog following a change in my life since my early adult life.

Compared to before, I was a person who consumed a lot until the day I understood that my consumption was making me sadder and poorer. From now on, I prioritize the minimum of my needs to be happy and achieve financial freedom.

Without realizing it, I also began to prioritize savings and investments to depend on a boss for as short a time as possible and to accelerate my personal projects.

For several years I have felt happy and I have become richer in a way that I would never have imagined given that I have an average salary in Switzerland.

It is for this purpose that I decided to create this blog. To share, learn and teach with others who seek freedom, simplicity and long-term wealth.

Are you rather minimalist or frugal Jonny?

I am both a minimalist and a frugalist. However, there are situations where I lean more towards an art of living.

To conclude, I think the most important thing is to feel comfortable in your life and I have found a balance between these lifestyles without reaching the extremes.
