Calculators
CalcuAutónomo
Calculator for the self-employed: from what you invoice to what you can actually spend, separating expenses, contributions, VAT and income tax.
The brief
Close the family of work-related calculators with the most confusing case: the freelancer, who watches money arrive that is largely not theirs.
The problem
Invoicing isn’t earning. Out of the money that comes in you have to set aside VAT — which was never yours — plus contributions, an income tax provision and expenses. Without that split it’s easy to spend money you actually owe the tax office.
The solution
The calculator starts from monthly invoicing and shows the real split: available to you, deductible expenses, self-employment contributions and the income tax provision. It works out the contribution bracket from your earnings, lets you adjust the withholding on your invoices, and separates VAT visually because it isn’t income.
It includes scenario comparison to see what changes if you invoice more, plus guides on brackets, VAT and income tax, and deductible expenses.
Everything is calculated in the browser, with no sign-up and no data sent.
Outcome
