French purchasing power in 2026: what the official figures don't tell you

French inflation stands at +1.7% year-on-year (CPI March 2026, INSEE provisional data). Officially, purchasing power is preserved. Yet on the ground, more and more households and businesses observe the opposite. This gap is not an irrational feeling: it stems from a statistical base change that optically erases four years of inflation, from how the index is built, and from which spending categories weigh most in real life. Here's what the official statistics don't tell, and why it directly concerns every company selling in France.

The 2026 paradox: low inflation, constrained purchasing power

In March 2026, INSEE publishes a provisional CPI at +1.7% year-on-year. A low, almost reassuring figure suggesting that prices are stable and that the 2022-2023 inflation crisis is behind us.

Yet household confidence surveys tell a very different story. Sentiment is below the long-term average, consumer spending is down 1.5% year-on-year, and the savings rate remains abnormally high, a classic sign of precaution about the future rather than economic dynamism.

How can we explain this gap between official indicators and perceived reality?

The answer is in two sentences: official inflation is an annual average, it describes neither households' real lives nor the cumulative price rises they've absorbed since 2022. Two biases combine: a temporal bias (how the figure is rebased every year) and a composition bias (how categories are weighted).

The base-change trap: why 2026 inflation looks softer than it really is

Since January 2026, INSEE has changed the CPI calculation base. The reference year, previously 2015, is now 2025. In practice, today's published index is compared against a 2025 basket, not against a historical one. It's a classic methodological adjustment (bases are revised periodically), but it has a powerful and rarely explicit reading effect.

Looking at the monthly figure (+1.7% year-on-year in March 2026), it feels like prices have almost stopped rising. Technically, that's true for this year. But it's misleading, because it optically erases the four previous years of massive inflation. The high level reached in 2024-2025 has become the new zero point of the reasoning.

The real figure is cumulative inflation. Using INSEE's annual averages:

Concretely, this means a product that cost €100 in early 2022 costs about €116 today. A household with a €2,500 monthly budget in early 2022 now has to spend the equivalent of €2,900 to maintain exactly the same standard of living, at identical basket. These extra €400 are not a feeling: they are documented by the indices themselves, simply spread over four annual publications instead of being aggregated into a single reading.

This is exactly why the gap between official inflation (+1.7% «only») and perceived inflation is so large. French households mentally compare their spending to 2020-2021, not to 2025. They are substantively right, INSEE simply doesn't communicate this cumulative figure visibly, because its role is to publish a monthly index, not a long-term narrative.

Low monthly inflation is therefore real, but it shouldn't be read in isolation. It doesn't mean prices have returned to normal: it simply means they are no longer climbing as fast. The levels reached between 2022 and 2024 have become the new base, and it's this high base that explains the lasting sense of expensiveness.

What the +1.7% hides: price dispersion across categories

The Consumer Price Index (CPI) is a weighted average of hundreds of products and services. Each category weighs in the index based on its share in the average French household budget. But some categories saw radically different trajectories in 2026.

In detail, over the past twelve months:

• Energy: +5.8%. The return of higher electricity, gas and fuel prices weighs heavily, particularly on households with poor insulation or who depend on their car to get to work.
• Food: +2.3%. Less spectacular than in 2022, but still above general inflation. Fresh products, in particular, continue to pull the index up.
• Services: +1.4%. Insurance, restaurants, hairdressing, personal services, all rising moderately but steadily.
• Manufactured goods: -1.2%. Clothing, appliances, furniture are falling. This decline in durable goods offsets the food and energy rises in the overall average.

The +1.7% average is mathematically correct. But it hides a massive redistribution.

A household that buys few manufactured goods but spends a large share of its budget on energy and food actually experiences annual inflation close to +3.5 to +5%. Conversely, a wealthy household that regularly renews its equipment and goes on holiday sees personal inflation close to +0.5%, or even negative. The annual gap with the official CPI is therefore 2 to 3 points, but it's the four-year cumulative figure (around +15 to +16% on the whole basket) that makes the burden so heavy on constrained budgets.

Official inflation is the average of these two realities. It describes neither one.

The three Frances of purchasing power in 2026

This isn't a theoretical view. INSEE's budget-family survey data make it possible to distinguish several typical profiles whose trajectories diverge significantly.

Constrained France

Lower-income and lower-middle-class households, urban or rural, owners or constrained tenants. For them, «non-compressible» expenses, housing, energy, food, constrained transport, make up 60 to 75% of the budget. Their personal inflation is structurally above average, and any energy or food shock translates into a direct loss of purchasing power.

Median France

Middle classes, often owners with ongoing mortgages, living in peri-urban areas. Their inflation tracks the official average fairly well, but with strong volatility depending on personal trade-offs: vehicle change, renovations, children's education. For them, the perception of inflation depends heavily on the year lived.

Protected France

Retirees with assets, senior executives, high-income households. The share of constrained expenses in their budget is lower, savings act as a buffer, and their consumption basket includes more goods whose prices are falling. Their personal inflation is typically below average.

Why this concerns every organisation, inter-business included

One might think purchasing-power questions only concern retailers, restaurants or consumer services. That's a mistake. Household purchasing power feeds the entire French economic chain, inter-business included, with a 3 to 6-month lag.

Three mechanisms to keep in mind:

1. Consumption funds employment, which funds business investment. When households cut their spending, retailers hire less, then invest less, then trim services (cleaning, maintenance, training, consulting). Inter-business providers working for these companies feel it one to two quarters later.
2. Confidence drives private investment. Surveys show a strong correlation between household sentiment and the investment intentions of small businesses run by entrepreneurs who are themselves households. When sentiment erodes, growth projects are postponed.
3. Energy prices pass through to every sector. +5.8% on energy is a structural cost rise for every industrial, logistics or tertiary activity. A business that doesn't monitor this category discovers the margin effect several months later.

Official inflation at 1.7% tells you nothing about what your business will actually face 6 months from now, nor about the ≈+15% cumulative hit your customers have already absorbed since 2022.

How to estimate your real inflation: a simple 4-step method

Rather than tracking an aggregate figure, any executive can build their own indicator in 4 steps.

1. Identify the categories that actually weigh in your costs. Energy, rent, raw materials, wages, transport. For a typical French business, these five categories often account for 70 to 85% of variable charges.
2. Measure their individual evolution over a 12-month rolling window. Official indices (detailed CPI, BT01, TP09, CNR, INSEE energy prices) provide reliable reference points.
3. Weight by the actual share in your P&L. Energy at +5.8% doesn't have the same impact whether it represents 2% or 15% of your charges.
4. Compare with the evolution of your revenue. It's that differential, not official inflation, that determines the pressure on your margin.

This «company inflation rate» is more useful to steer than the national CPI, because it reflects your real exposure.

What to monitor in 2026

Several signals deserve particular attention in the coming months.

In summary

French purchasing power in 2026 cannot be read in a single figure. Official inflation at +1.7% is technically correct, but it ignores the ≈+15% cumulative rise since 2022, hides very different realities depending on the household, and leaves out transmission mechanisms that affect every organisation, consumer-facing and inter-business alike.

For an executive, the right question isn't «what is inflation in France?» but «what inflation do my customers experience, and what inflation hits my own cost structure?». The two are different, and neither matches the INSEE average.
