Gross ↔ net pay before income tax

Estimate gross-to-net pay or reverse the calculation. The contribution rate remains adjustable so the assumption is explicit.

Indicative value only. The actual rate varies with status, compensation and circumstances.

How does this tool work?

This calculator estimates how a gross salary turns into net pay before income tax, or the other way round. To stay transparent, it applies one overall employee contribution rate that you can see and change, rather than pretending to reproduce a complete French payslip.

In gross-to-net mode, the engine subtracts the contribution percentage you set from gross pay. The result is pay after social contributions but before income tax is withheld.

In net-to-gross mode, the reverse calculation rebuilds the gross salary that matches a given net-before-income-tax amount at the chosen rate.

Monthly and annual equivalents are based on 12 months. The calculation never adjusts the rate to your salary level: it remains an explicit assumption that you control.

How to use this tool

  1. Choose the direction

    Select gross to net or net to gross.

  2. Choose the period

    Pick a monthly or an annual amount.

  3. Enter the amount

    Type the pay figure you already know.

  4. Check the assumption

    Adjust the estimated contribution rate if needed before reading the result, ideally using the rate shown on your payslip.

Simplified gross ↔ net formulas

The calculation uses an overall contribution rate selected by the user.

Gross to net before income tax

Net = Gross × (1 − Contribution rate / 100)

At €3,000 gross and 22%, estimated net is €2,340.

Net to gross

Gross = Net / (1 − Contribution rate / 100)

The reverse calculation is not performed by simply adding the same percentage.

Estimated contributions

Contributions = Gross − Net before income tax

This is an overall estimate, not a payslip breakdown.

The gross/net relationship depends on payroll rules and individual circumstances; one rate can only provide an estimate.

Understand the calculation and its limits

Why is the rate adjustable?

Actual deductions depend on employment status and payroll circumstances.

  • Visible assumption
  • No false universal rate

Gross/net or hourly/monthly?

These are different conversions: deductions versus compensation period.

  • Gross ↔ net: contribution estimate
  • Hourly ↔ annual: time conversion

Use cases

Read a job offer

Get a quick idea of the net-before-income-tax pay behind an advertised gross salary.

Compare two pay packages

Bring several amounts back to a comparable monthly or annual basis.

Find a target gross salary

Estimate the gross salary you would need to reach a given net-before-income-tax amount.

Test several assumptions

Change the contribution rate and watch its effect, without the assumption being hidden from you.

Examples

€3,000 gross monthly

Estimated net before income tax: €2,340; estimated contributions: €660.

Input

€3,000 gross · indicative rate 22%

€2,500 net before income tax

Estimated corresponding gross: about €3,205.13.

Input

€2,500 net · indicative rate 22%

Tips and best practices

  • Treat the result as a ballpark figure, not as the exact amount of a future payslip.
  • To compare two offers, use the same rate assumption for both or, better still, the precise figures provided by the employer.
  • Income tax withheld at source comes after net-before-income-tax pay and is not calculated here.

Frequently asked questions

What percentage should I deduct from gross pay?

There is no single percentage that applies to every employee. The rate depends on your status, your pay level and several payroll rules, so the calculator uses an assumption you can change.

Is the result my take-home pay after income tax?

No. The result estimates net pay before income tax is withheld at source.

Why does net to gross divide by a coefficient?

Because net pay is a fraction of gross pay. If net is 78% of gross, you divide the net amount by 0.78 to get back to the gross salary.

Can I use this result to negotiate a salary?

Yes, as an order of magnitude. A precise comparison must also take into account your status, bonuses, benefits, collective agreements and other parts of the pay package.

How do I then convert a monthly salary into an hourly rate?

Use the hourly, monthly and annual salary calculator, which is built specifically for converting pay between time periods.

Why is 22% the default rate?

It is an order of magnitude for employee social contributions of a non-executive private-sector employee in France. For executives, special contracts or other countries the rate can differ: replace it with the one on your payslip.

How do I convert an annual salary into a monthly one?

Choose the annual period: the tool spreads the amount over 12 months and shows gross and net monthly equivalents. If your contract includes a 13th-month payment, the amount actually paid each month will be lower than this equivalent.
