Methodology: how we calculate your net salary in Spain

This page explains what our calculators do, where the figures come from, how we keep them current and what the estimate does not cover. It is the site's editorial policy.

What the calculators compute

  • Employee social security contributions: common contingencies, unemployment, vocational training and the intergenerational equity mechanism, within the year's minimum and maximum contribution bases.
  • IRPF withholding: the state scale plus your autonomous community's scale, personal and family allowances, and the earned-income reduction.
  • Net salary in 12 or 14 payments, from annual or monthly gross pay.
  • The other tools (unemployment, retirement, severance, mortgage, VAT…) apply the formulas described on each page, with their own sources.

All calculations run in your browser: nothing you enter is sent or stored.

Our sources

Updates

  • Contribution bases and rates are reviewed every year with the contribution order published in the BOE.
  • State and regional IRPF scales are reviewed with each budget act or tax reform.
  • Every page shows, at the top and the bottom, the real date of its last change.

Limits of the estimate

Our calculators give an estimate for guidance only. Your employer sets the actual withholding with the official algorithm and your form 145 data; your final IRPF liability is settled in your annual tax return. Some cases are not modelled (the Basque Country and Navarre foral regimes, irregular income, several payers). If in doubt, the tax authority's decision prevails.

Report an error
