When preparing a salary grid or estimating a temporary work quote, the first reflex is to check the gross hourly rate of the minimum wage (SMIC). Since 2022, this reflex has occurred more often than before: adjustments have multiplied throughout the year, making monitoring significantly more demanding for employers as well as payroll managers.
Anticipated adjustments of the SMIC: an unprecedented pace since 2022
Before the inflation shock, we had become accustomed to a single adjustment per year, on January 1st. The mechanism was predictable: INSEE published the price index, the government applied the legal formula, and payroll software was updated once.
Starting in 2022, everything changed. The SMIC rose from 10.57 euros gross per hour in January 2022 to 11.07 euros in August of the same year, after an intermediate step at 10.85 euros in May. Three increases in the same year, an unprecedented occurrence in recent times.
In 2023, the pattern repeated itself with a rise from 11.27 euros in January to 11.52 euros in May. To understand the evolution of the hourly SMIC rate during this period, it is important to remember that these adjustments are not the result of a political choice: they are triggered automatically as soon as the consumer price index increases by at least 2% compared to the last adjustment.
This mechanism, provided for by the Labor Code, has produced a rapid staircase effect that many employers had never managed in practice. Concretely, this involves recalculating the conventional minimums, adjusting part-time contracts, and ensuring that bonuses are not absorbed by the new floor.
Gross SMIC and net monthly SMIC: two figures not to be confused
Official sources almost always communicate in gross hourly terms. This is logical from a legal standpoint, but the net monthly amount remains the concrete reference for employees. The difference between the two depends on social contributions, which vary according to status and applicable exemptions.
As of January 1, 2024, the gross hourly SMIC was set at 11.65 euros, which translates to a gross monthly amount of 1,766.92 euros for 151.67 hours. In net terms, this represented approximately 1,398.69 euros. After the adjustment on November 1, 2024, the gross hourly rate rose to 11.88 euros (1,801.80 euros gross monthly), and the net reached 1,426.30 euros.
For a payroll manager or a TPE leader, here are the concrete points of vigilance during an adjustment mid-year:
- Ensure that the hourly rate applied in the payroll software corresponds to the new amount from the month it takes effect, not the following month
- Recalculate employer contribution reductions (Fillon reduction), whose ceiling is directly indexed to the SMIC
- Check branch minimums: if the collective agreement provides for a first level below the new SMIC, the SMIC applies by right
- Update part-time contracts, where the most frequent error is applying the old rate on a non-revised amendment
Hourly SMIC between 2019 and 2024: a trend break
When aligning the figures, the break is striking. Between 2019 and 2021, the gross hourly SMIC increased from 10.03 euros to 10.48 euros, a moderate progression. Then, in three years (2022-2024), it surged from 10.57 to 11.88 euros.
| Effective Date | Gross Hourly SMIC | Gross Monthly SMIC (151.67 h) |
|---|---|---|
| 01/01/2019 | 10.03 € | 1,521.22 € |
| 01/01/2020 | 10.15 € | 1,539.42 € |
| 01/01/2021 | 10.25 € | 1,554.58 € |
| 01/01/2022 | 10.57 € | 1,603.12 € |
| 01/08/2022 | 11.07 € | 1,678.95 € |
| 01/01/2023 | 11.27 € | 1,709.28 € |
| 01/05/2023 | 11.52 € | 1,747.20 € |
| 01/01/2024 | 11.65 € | 1,766.92 € |
| 01/11/2024 | 11.88 € | 1,801.80 € |
In two years, the hourly SMIC has increased more than in the previous five years combined. This catch-up directly reflects the surge in inflation, which peaked at 6.3% in February 2023 before falling to 1.2% in October 2024.
The 2024 report from the group of experts mandated by France Stratégie highlights that the SMIC slowed down in 2024, with an increase of only 1.1% year-on-year in the second quarter, compared to 6.2% a year earlier. At the same time, the average salary per head in the market sector rose by 2.8%. This gap means that employees earning above the SMIC saw their remuneration increase faster than the legal minimum in 2024.
Outlook after 2024: what employers need to anticipate
The SMIC was not adjusted on January 1, 2025. This unusual absence of an increase after three years of frequent adjustments is explained by the significant decline in inflation. The next confirmed increase is scheduled for January 1, 2026, at 12.02 euros gross per hour, which translates to a monthly amount of 1,823.03 euros.
For companies, two operational elements deserve attention. First, the compression of salary grids remains an open issue. The rapid increases in the SMIC between 2022 and 2023 have reduced the gap between the first and second levels in many sectors. Some agreements have still not caught up with this discrepancy.
Next, feedback varies on the actual impact on purchasing power. While the gross SMIC has increased significantly, food and energy inflation has absorbed a significant portion of the gain. INSEE data on the purchasing power of the SMIC shows a real improvement, but more modest than what the gross figure alone suggests.
For a payroll manager or an accountant, the practical lesson from this 2022-2024 sequence is to no longer rely on a single annual calendar. Setting up monitoring on the consumer price index allows for anticipating automatic adjustments before they appear in the Official Journal, and avoiding last-minute corrections on payslips.
