Why do other calculators show a different figure?
Because they include different coverages. We apply the 30.50 % of article 18.2. Figures published at 31.50 % add cese de actividad and formación profesional, set in a different chapter of the same order. Neither is wrong: they cover different things.
This is an estimate. The exact amount depends on the coverages chosen, and the Seguridad Social regularises at year end against your real earnings.
