The 50-30-20 rule: How to budget and save wisely

Would you like to organize your finances better? The 50-30-20 rule is a simple way of dividing income in a meaningful way. Particularly in Switzerland, where fixed costs such as rent and health insurance are often high, you need a clear overview of your own budget.

But how does the 50-30-20 rule work? How can it be used in everyday life? And is it realistic? In this blog, you’ll find out step-by-step how to use the savings method to be more aware of your money and to build up savings over the long term.

What does the 50-30-20 rule mean?

The 50-30-20 rule is a simple budget rule of thumb. Your monthly net income is divided into three categories:

• 50 percent for basic needs and fixed costs
• 30 percent for personal wishes and leisure
• 20 percent for saving or reducing debt

The method is designed to help you carefully structure your expenses and plan for a fixed savings component. Those in particular who previously lived without a fixed budget can thus get a quick overview of their finances.

The rule is based on your net income, i.e. the amount that actually goes into your account each month.

How does the 50-30-20 rule work? 

The principle behind the 50-30-20 rule is kept deliberately simple. Instead of tracking every single expense down to the last detail, income is roughly structured. This creates a realistic budget framework that is easier to adhere to in everyday life. Example: 

A monthly net income of CHF 5,000 breaks down as follows: 

• CHF 2,500 for fixed costs and basic needs
• CHF 1,500 for leisure and personal wishes
• CHF 1,000 for saving or investing

This keeps the budget clear and flexible at the same time.

Is the 50-30-20 rule also suitable for families?

In principle, yes, but it may need to be individually adapted, as families often have higher living and childcare costs. At the same time, their income may be lower if parents are working less in favor of their children. Here, the division can be flexibly structured according to requirements, for example with 60 percent fixed costs and 20 percent each for wishes and savings.

The 50-30-20 method therefore varies depending on your life situation. It is not a rigid rule, but a guide. The decisive factor is not that the percentages are adhered to perfectly, but that money is handled carefully.

Is the 50-30-20 rule realistic? 

Whether the 50-30-20 rule is realistic depends greatly on income and living costs. In expensive cities in particular, rent, health insurance and insurance often account for more than 50 percent of income. 

This is why the method in its pure form is particularly suitable

• as an entry into budget planning,
• to improve control of expenditure,
• for people without a clear savings system or
• to build consistent saving routines.

The most important thing is to save money regularly – even if the distribution is more likely to be 60-20-20 or 70-20-10.

When does the 50-30-20 rule make sense?

This saving method is suitable for you if you

• want to structure your finances,
• create a budget for the first time,
• want to have a better overview of fixed costs,
• want to define savings goals or
• set up automatic standing orders for saving.

Young adults in particular who have just received their first salary benefit from the 50-30-20 rule. It can be a good starting point for building healthy financial habits.

How can the 50-30-20 rule be applied in practice?

1. Calculating net income

First of all,  your monthly net income is calculated, excluding one-time bonuses and irregular income. However, your salary, secondary income, and regular additional income are taken into account.

2. Analyze expenses

In the next step, all monthly expenses are recorded and analyzed. In doing so, it is often possible to identify potential savings. Typical cost categories include: 

• Rent
• Insurance
• Food
• Subscriptions
• Mobility
• Leisure
• Debts
• Clothes

3. Dividing the budget according to the 50-30-20 rule

Revenue will now be allocated to the following three categories: basic needs, wishes and savings.

4. Automatic saving

This method is particularly effective if the savings amount is automatically transferred directly after you receive your salary. This reduces the temptation to spend the money elsewhere.

What strategies can I use to save wisely under the 50-30-20 rule? 

Tip 1: Optimize fixed costs 

If you want to save money, you should first consider the largest cost blocks:

• Compare health insurers
• Cancel unnecessary subscriptions
• Check forcheaper insurance
• Analyze housing costs

Even small savings can make a big difference in the long term.

As an AXA Healthcare customer, you can also benefit from our switching service: you choose your new basic insurance – we terminate your current insurance and handle the switching process for you.

Tip 2: Spend money on your wishes more carefully

The 30 percent category does not mean unlimited spending. It makes sense to set a fixed leisure budget for: restaurants, shopping, vacations and hobbies. This allows spontaneous expenses to be better controlled.

Tip 3: Prioritize saving and investments

The 20 percent savings component can be used for various purposes:

• Building up emergency money
• Accumulating assets over the long term
• Placing money in investments – even small amounts
• Strengthening retirement provision through Pillar 3a
• Reducing debt

Long-term savings goals in particular benefit from automatic deposits.

What are the alternatives to the 50-30-20 rule?

Not every budget method is suitable for every situation in life. Alternatives to the 50-30-20 rule include: 

• Zero-based budgeting: every franc has a fixed purpose
• 80-20 rule: save 20 percent, use the rest flexibly
• Envelope budgeting: fixed cash budgets per category
• Pay yourself first: save before spending

If you have very high fixed costs, you often need more individual budget models.

Summary: the 50-30-20 rule as an easy way to get started

The 50-30-20 rule is a simple and practical savings method for structuring your own finances. It helps you to carefully plan fixed costs, wishes and savings goals and to better understand your own spending behavior.

Even if the distribution cannot always be exactly adhered to, the method offers a clear framework for dealing with money. It’s not so much the perfect percentage as the habit of saving regularly and actively controlling your own finances.

If you want to build up savings or create financial security over the long term, you can use the 50-30-20 rule as a solid basis for personal budget planning.
