This is a pro feature

You can test the calculator with values under the minimum wage (€17,100 per year). No limits, no signup required. For values above that, get Pro.

Hints

Social Security regularizes a year once the tax office has told them what you really earned, which is why this calculator opens on the last closed year rather than the current one.

Pick the year the letter is about, or the year you are worried about.

per year Hints

Your autónomo income before expenses, for the whole year.

If you have your modelo 130 forms to hand, use the detail button instead and copy the boxes across. That is more accurate, and it lets the calculator work out the rest for you.

per year Hints

Your deductible autómomo expenses for the year.

per year Hints

Everything that left your account for your own cuota that year, before any refund.

Note that the regularización payment for the previous year does not count towards this total!

Hints

Months you were signed up as autónomo that year. If you entered your payments month by month, this follows from what you filled in.

Hints

You are, if you are self-employed through a company you control. It changes the generic deduction from 7% to 3% and puts a floor under your contribution base, so both halves of this calculation move.

discounts

Pick one if you know you qualify. Most of these have to be applied for, and none of them are granted automatically.

Hints

Tarifa plana, cuota cero and the rest are taken into account here: their months are priced by their own rules, and the law keeps most of them out of the regularización altogether.

Pick the one that ran during the year you are calculating, then say how many of its months you had already used, because that is what decides whether the year is settled at all.

These numbers are estimations. This tool can make mistakes and cannot account for all individual circumstances. For definite numbers, consult a tax professional.

What you paid, month by month

Fill in what you actually paid each month. Leave a month blank if you were not registered. This matters when your cuota changed during the year, because Social Security settles month by month, not on the year as a whole.

Your modelo 130, quarter by quarter

Copy the figures straight off your forms. Modelo 130 is filed cumulatively, so each quarter already contains the ones before it: box 01 in Q3 is your income for January to September, not for July to September. Enter them exactly as they appear and the calculator will read them correctly.

MEI (Mecanismo de Equidad Intergeneracional)

MEI is an extra Social Security contribution that funds the state pension reserve. In 2026 it is 0.90% of your contribution base, paid in full by the self-employed. It rises 0.1 points a year to 1.2% in 2029 and buys you no additional pension rights.
