Self-employed contribution calculator
The estimate applies the minimum base for each income band and the general rates published for 2026.
Methodology, limitations and sources
How it is calculated
Selects the 2026 minimum base for the net-income bracket and applies the estimated general rate. For company autónomos it respects the statutory minimum base.
Example
For monthly net income of €1,500, it shows the bracket's minimum base and indicative monthly and annual contributions.
What is not included
It does not replace the Importass calculation. Reliefs, multiple employment, cover and the reduced contribution can change the final amount.
