Hourly, monthly and annual salary: convert in one click

How it is calculated

Three conversions done in code, then the engine for the net. The hourly rate becomes a monthly figure by multiplying it by the month's hours: 35 hours a week × 52 weeks ÷ 12 months = 151.67 h for full time, or your own weekly hours run through the same formula. The monthly figure becomes a yearly one by multiplying it by the number of months paid; the other way round, the yearly figure is divided by that number, then by the month's hours.

The net is then calculated by the modele-social engine on the average monthly gross, with the general scheme's contributions; the net hourly and yearly figures follow from the same conversions. If you enter a net figure, the gross is found by numerical inversion before the three periods are worked out.

Below 35 hours a week, the tool adds the full-time equivalent: the gross you would get for the same hourly rate on full time, and its net. That is the figure to compare with job ads, almost always quoted for full time.

What the result includes

So that two people get the same figure from the same gross pay, the site always calculates from the same baseline situation. Each line can be changed in the calculator's options where it matters.

• General social security scheme (régime général), rates as of 26 October 2026 (rules from modele-social, the engine behind URSSAF's simulator).
• Permanent full-time contract (CDI), 35 hours a week, i.e. 151.67 h a month, paid over 12 months.
• Non-cadre by default (cadre status is one button away), collective agreement set to the general rules (“droit commun”).
• Company health cover (mutuelle) of €40 a month, of which €20 is deducted from pay, URSSAF's default setting; zero is possible in the options.
• Outside Alsace-Moselle (option available), without meal vouchers or benefits in kind.
• Before income tax: tax withheld at source depends on your household and comes on top (see the “net after tax” tool).
• Minimum wage (SMIC) since 1 June 2026: €12.31 gross per hour (service-public.gouv.fr).
• Contract hours as entered: they set the hourly gross and the full-time equivalent; the net keeps full-time rules.

Limits

A correct calculation for a typical situation is not your payslip. Here is what the tool does not know, so that you read the result as a reliable order of magnitude, not a promise.

• Collective agreement: sector minimums, seniority bonuses, compulsory thirteenth month and specific provident schemes are not taken into account (general rules only).
• Bonuses, variable pay, overtime, benefits in kind: left out, except in the tools that ask for them.
• Health cover and provident scheme: your actual contribution may be different; change it in the options.
• Alsace-Moselle: the option adds the local scheme's health contribution, without its other specifics.
• Public sector not covered: civil servants' pay scales and contributions follow other rules.
• Simplified tax: no tax reductions or credits, no exceptional income; the engine's “tax” module is flagged as experimental by URSSAF.
• Overtime and additional hours: carrying a premium and partly exempt, they are not ordinary hours; see the dedicated tool.
• Day-based contracts (forfait jours) for cadres: no reference hours, so the hourly rate shown is only indicative.

From hourly rate to monthly and yearly pay

First row: the hourly minimum wage (SMIC) in force since 1 June 2026 (service-public.gouv.fr). Full time, twelve months, non-cadre, estimated net before tax.

Part time and full-time equivalent

For €3,000 gross a month on full time, here are the part-time gross and net figures for a few common schedules, calculated with the engine's part-time rule (gross in proportion to hours, contributions adjusted). The full-time equivalent stays at €3,000 in every case: that is what the tool shows under the result as soon as your hours drop below 35 a week.

A part-time contract keeps the same hourly rate as full time in the same job: if you are offered a monthly amount, bring it back to the hour before judging it. For a complete calculation (share of full time, additional hours), use the part-time salary tool, and to put your hourly rate in context, the SMIC guide, calculated for 35 hours as for any other schedule.
