How much should you save each month?

A starting point: at least 10%, 20% if you can

Most rules of thumb revolve around a share of your net income: 10% to begin with, 20% once your budget allows it. On €2,200 net a month, that means €220 to €440 set aside, or €2,640 to €5,280 over a year.

These percentages are not a law. They give you an order of magnitude, which you then adjust to your situation: heavy rent, an existing loan or children to support will all move the dial. Better to put aside €50 every month for ten years than €500 once and nothing after that.

The 50/30/20 rule, French version

The most quoted method splits your net income three ways: 50% for needs, 30% for wants, 20% for savings and debt repayment. Needs are housing, groceries, transport, energy, insurance and health; wants are everything else.

It was designed in a context where housing weighs less than it does in France, especially in big cities. Here it is more often read as 55/25/20 or 60/25/15. With €2,200 net, the 55/25/20 version gives €1,210 for needs, €550 for wants and €440 for savings.

• Add up your real needs over three months, without rounding down.
• If needs exceed 60%, do not give up on saving: set it at 10% and trim your wants first.
• Revisit the percentages whenever your situation changes: a move, a birth, a pay rise.

Safety buffer first: 3 to 6 months of spending

Before funding a project, build a cushion that can absorb the unexpected: a broken-down car, a loss of income, a repair. The usual rule of thumb is three to six months of living costs, meaning what you spend to live, savings not included.

With €1,760 of monthly spending, the target is €5,280 to €10,560. Three months is generally enough for a salaried employee on a permanent contract (CDI) whose household has two incomes; six months or more is safer for a freelancer, someone on a fixed-term contract (CDD) or a household that relies on a single salary. At €220 a month, €5,280 takes 24 months: that is a long time, which is why it pays to start early.

This cushion has to stay available immediately and with no risk to your capital. Regulated savings accounts such as the Livret A (a French tax-free savings account, capped at €22,950) or the LDDS (a similar account, capped at €12,000) meet that test; check the current rates when you open one, as they change.

Start from the goal rather than the income

For a dated project, the calculation flips: divide the amount you are aiming for by the number of months available. €3,000 for a holiday in 10 months needs €300 a month; a €12,000 deposit in three years needs €333 a month (12,000 ÷ 36).

Then compare that figure with what you can realistically free up: net income minus the month’s spending. If the gap is positive, the project is achievable; if not, stretch the timeline, lower the goal or free up some budget. Our savings simulator does this calculation for you and shows the date you will get there.

Automate: pay yourself first

Saving “whatever is left” often comes to nothing, because what is left gets spent before you see it. The fix fits in one line: a standing order, the day after payday, to a separate savings account, for a fixed amount.

Pick an amount you will not notice, then raise it in steps. €150 a month makes €1,800 a year. A simple rule: with every pay rise, half goes straight into savings and the other half improves your everyday life. Keep the savings account’s bank card at the back of a drawer, or do not ask for one at all.

The three most common traps

The first is saving while you are repaying a high-interest consumer loan: the cost of the credit often exceeds what a savings account earns. The second is forgetting annual expenses: a €480 insurance premium paid in one go, a property tax bill, end-of-year gifts. Divide them by twelve and treat them as a monthly cost: €1,200 of annual expenses means €100 to put aside every month.

The third is giving up after the first slip. A month without a transfer cancels nothing; what matters is picking it up again the next month. This article is not personalised investment advice: it gives budgeting benchmarks, not an investment recommendation.
