The VAT calculator lets you add VAT to a pre-tax price (net amount) or, the other way round, extract VAT from an already paid price, using Spanish rates (21% standard, 10% reduced and 4% super-reduced). Useful for quotes, invoices, receipts and for knowing how much of the final price is tax. Use it as many times as you need: it is completely free, requires no sign-up and works directly in your browser.
Frequently asked questions
¿Cómo calculo el IVA de un importe?
Multiplica la base por el tipo: para 21%, base × 0,21 es la cuota de IVA, y base × 1,21 es el total. Para quitar el IVA de un total, divide entre 1,21 (o el tipo correspondiente).
¿Qué tipos de IVA hay en España?
General 21%, reducido 10% (alimentos, vivienda nueva, restaurantes) y superreducido 4% (productos básicos como pan, leche o libros).
¿Influye el redondeo en el resultado?
Los importes se redondean a céntimos, como en las facturas reales. Si calculas con más decimales, podrías ver diferencias de 1 céntimo.
How do I calculate VAT on an amount?
Multiply the net amount by the rate: for 21%, net × 0.21 is the VAT amount, and net × 1.21 is the total. To remove VAT from a total, divide by 1.21 (or the matching rate).
What VAT rates are there in Spain?
Standard 21%, reduced 10% (food, new housing, restaurants) and super-reduced 4% (basic products such as bread, milk or books).
Does rounding affect the result?
Amounts are rounded to cents, as on real invoices. If you calculate with more decimals you might see 1-cent differences.
