Savings and inflation: how to know if your money is losing value

The trap: your money goes up, but its value can fall

When you put money into a savings account, you mostly see the balance shown by the bank. If you have €10,000 and your account pays 1.5%, you may end up with €10,150 after one year. On screen, everything looks fine: the amount has increased.

But that number does not tell the whole story. If prices rise faster than your savings grow, you can have more euros than before while being able to buy less. That is the effect of inflation: it does not remove money from your account, it reduces the buying power of each euro.

That is why you need to distinguish two values:

• the displayed balance, meaning the nominal amount visible on your account;
• the real value, meaning what that amount represents in purchasing power after inflation.

A savings account can therefore protect your capital in euros without fully protecting your purchasing power.

2026 figures to keep in mind

This guide is updated on June 2, 2026. Savings account rates, inflation and tax rules may change over time. The examples below are meant to explain the mechanism, not to provide personalized financial advice.

From February 1, 2026, the Livret A rate is 1.5%, the LEP rate is 2.5%, and the LDDS follows the Livret A at 1.5%. The French Ministry for the Economy explains that these rates are part of regulated savings, and that the Banque de France regularly calculates them using a formula linked in particular to inflation and short-term interest rates.

In May 2026, preliminary French inflation is estimated at 2.8% year-on-year, according to INSEE data reported by Reuters. This means that a 1.5% savings account can be positive on your account statement but negative in real value.

How to calculate the real value of your savings

The simplest formula is:

Real value = future amount / (1 + inflation)

Over several years, inflation compounds:

Real value = future amount / (1 + inflation)^number of years

To directly compare an interest rate with inflation, you can calculate the real return:

Real return = ((1 + net rate) / (1 + inflation)) - 1

Simple example with €10,000 on a Livret A at 1.5%, and inflation at 2.8%:

• displayed balance after one year: €10,150;
• real value after inflation: about €9,874;
• loss of purchasing power: about €126.

The key point: you did not lose euros on your account. You lost buying power.

What rate do you need to beat inflation?

To preserve your purchasing power, the net return on your savings must be close to inflation. To increase your purchasing power, it must be higher than inflation.

To preserve purchasing power: net rate ≈ inflation
To beat inflation: net rate > inflation

The important word here is net.

The Livret A, LDDS and LEP are exempt from income tax and social contributions. Their rate can therefore be compared directly with inflation. By contrast, a standard taxable savings account may be subject to the 30% flat tax. In that case, you need to compare inflation with the after-tax rate, not the gross rate advertised by the bank.

Example: if a taxable savings account shows 4% gross, with 30% taxation, its net rate is about 2.8%. With inflation at 2.8%, it barely preserves purchasing power before any other conditions.

Livret A, LEP, LDDS: how do they compare with inflation?

Here is a simple reading using figures known on June 2, 2026.

Livret A

• Rate: 1.5%
• Interest taxation: exempt from income tax and social contributions
• Main ceiling: €22,950 for an individual
• Reading against 2.8% inflation: the real return is negative in this example. The Livret A protects the displayed capital, but not fully the purchasing power.

LDDS

• Rate: 1.5%
• Interest taxation: exempt from income tax and social contributions
• Main ceiling: €12,000
• Reading against 2.8% inflation: same logic as the Livret A. The balance can increase while the real value can fall if inflation remains higher than the rate.

LEP

• Rate: 2.5%
• Interest taxation: exempt from income tax and social contributions
• Main ceiling: €10,000
• Reading against 2.8% inflation: better protection than the Livret A in 2026, but still slightly below inflation in this example. It is reserved for eligible savers based on income.

Taxable bank savings account

• Rate: variable depending on the bank and offer
• Interest taxation: often subject to the 30% flat tax
• Main ceiling: variable depending on the product
• Reading against inflation: compare the net rate after tax, not the gross advertised rate.

The LEP is therefore more protective than the Livret A in 2026, but it is subject to income conditions. The Livret A remains more universal and simpler. The right use mostly depends on the role of the money: emergency savings, short-term cash, or capital intended to work over a longer period.

The right role of a savings account

A regulated savings account is not useless just because it does not always beat inflation. That would be too blunt.

Its main role is rather to:

• keep money available;
• avoid capital loss risk;
• separate emergency savings from the current account;
• access money quickly when something unexpected happens.

The problem begins when you ask it to do something else: build long-term returns or consistently beat inflation. At that point, you need to understand the gap between displayed rate and real value.

Use the Outilo calculator

The Savings vs inflation: the real value of your money tool lets you simulate this gap with your own settings:

• starting capital;
• monthly contribution;
• savings rate;
• inflation;
• possible taxation;
• projection duration.

It compares the displayed balance with the real value in today’s euros. This is often more meaningful than a simple rate, because you can see how much purchasing power may disappear over time.
