The rule 50 / 30 / 20
I explained in my article “ The rule 50 / 30 / 20 ”"that for a beginner in budget management regarding personal expenses. Good management would be to:"
- 50% mandatory expenditure
- 30% of pleasure expenses
- 20% savings and investment
In reality, this financial rule is an excellent starting point for managing your budget and improving your personal finances!
👉 However, I think this 50/30/20 rule is not suitable for the majority of frugal and minimalist readers of this site ⚠️
Mainly those who:
- Are accustomed to a frugal and minimalist lifestyle
- Have rather high incomes
Why is the 50/30/30 rule not suitable for frugalists?
Mainly for 2 reasons:
- 30% leisure is a high percentage
For example, if we calculate 30% from a net income of 5,000 CHF. That's 1,500 CHF of leisure per month.

Therefore, spending 1,500 CHF per month just for leisure activities is rarely frugal 🤭
Don't forget: the more you spend on leisure, the less money you automatically have to invest!
- 20% investment and savings rate is a low percentage for an investor
The majority of readers of this blog wish to achieve future financial independence (FIRE) and maximize the returns on their investments every month.
To achieve financial freedom, it is often imperative to invest larger amounts of money each month.
Therefore, taking into account the 50/30/20 rule1. The percentage of savings and investment is only 201%. This percentage is, in my opinion, rather low. 🔺
For example, out of the 20% of monthly investment, there are 15% for investments and 5% for savings.
👉 In this case, on a net salary of 5,000 CHF, 15% is “only” 750 CHF invested each month!
Let's imagine that there are 2,500 CHF of monthly mandatory expenses. Because the 50% of a salary of 5,000 CHF net is 2,500 CHF.
I went to moneyland's FIRE calculator. And I calculated the number of years to wait to become financially independent with:
- 2500 CHF of mandatory expenses per month, once FIRE
- Investment of 750 CHF per month until you become FIRE
- 5% annualized return on average, on the 750 CHF per month invested
In this case, the FIRE (financially independent) day will be in … 33 years 😶

Waiting 33 years to become FIRE is quite a long time 😶. Furthermore, this FIRE calculation only considers mandatory expenses.
We therefore conclude that to become financially independent, it is important to invest a larger share of one's income.
How to organize personal expenses to optimize financial independence?
➡️ We're reducing spending and increasing investment!
⚠️ I'm not saying it's obvious!
To make this change, you have to be disciplined and careful with your budget. But personally, I managed to do it with a low-mid income.
👉 In reality, I apply the 45/20/35 rule
Broadly speaking, I divide my budget between:
- 45% of mandatory expenses (of which a maximum of 20-25% is for housing)
- 20% pleasure spending
- 5% savings
- 30% investments

🔺Note that one of the best ways to achieve this rule is to apply each step on the page savings/frugalism from my blog 😊
I can guarantee that it's possible to live frugally and minimalistly on an average salary. Managing your budget isn't an impossible mission!
Also, my low consumption regularly makes me happy 😉.
Why prefer this 45/20/35 rule?
👉 To achieve financial freedom much faster 🤩
I'm using the FIRE Moneyland calculator again, with 45% in mandatory expenses and 30% in investments, and an annualized return of 5%. Financial freedom will be achieved in:

Hop! 12 years of financial freedom gained 😉
In fact, this rule allows you to become financially independent in less than 22 years!
Note that in the previous example, it took 33 years to become FIRE-compliant with 151 TP3T of investments and 501 TP3T of expenses. With 301 TP3T of investments and 451 TP3T of expenses, this is reduced to 21.5 years.
That's 11.5 years gained as a FIRE member 😉. That's not insignificant.
How to invest your money wisely?
Please note that this article is not investment advice. Investing involves risk of losing money.
In my opinion, with good knowledge, there are several financial investments to analyze. For example:
- Buying your main residence
- Investing in the stock market and buying growth ETFs
- Investing in physical real estate
- Owning SCPIs
- Owning a high-dividend equity ETF
In reality, every investor will need to analyze their investment portfolio so that it is diversified and profitable!
It should be noted that a good, regular return can allow for early retirement with a good standard of living and a prosperous financial situation.
Conclusion
➡️ Although the 50/30/20 rule is a great rule for beginners in personal finance. According to my In my opinion, this is too flexible a rule for people used to linking minimalism and frugality.
👉 If your personal finances allow, I think it's best to use the 45/20/35 rule to maximize financial independence and save money 😊
🔺Increasing investments boosts the chances of increasing passive income. Therefore, more income means fewer years depending on a client or boss 🤓
➡️ In my opinion, the 45/20/35 rule is more suitable for the majority of readers of this blog than the 50/30/20 rule.

Without realizingI started to focus on saving and investing to depend on a boss for as little time as possible and to speed up my personal projects.

It is for this purpose that I decided to create this blog. In order to share and learn with other people who seek freedom and simplicity 😉
