Formula and Parameters

Two directions depending on whether your input is tax-inclusive (total with tax) or tax-exclusive (net before tax):

inclusive = exclusive × (1 + rate/100)
Tax-Inclusive → Tax-Exclusive
exclusive = inclusive ÷ (1 + rate/100)
Tax Amount

Frequently Asked Questions

What's the difference between tax-inclusive and tax-exclusive pricing?

Tax-inclusive means the displayed price already includes VAT/sales tax — common in the EU where consumers see the final price. Tax-exclusive means tax is added on top at checkout — common in the US. This calculator converts between both directions.

Which countries and rates are built in?

We include standard rates for 20+ countries: UK (20%), Germany (19%), France (20%), Spain (21%), Italy (22%), Poland (23%), Norway (25%), Switzerland (7.7%), Japan (10%), Canada (13%), Australia (10%). You can also enter any custom rate.

Is my pricing data stored or sent anywhere?

No. All calculations happen entirely in your browser. Amounts, tax rates, and country selections are never transmitted to any server.

Can I use this for invoicing or tax filing?

This calculator is for estimation only. Real invoicing depends on your country's specific VAT rules, reverse-charge mechanisms, reduced rates, and whether you're VAT-registered. Always consult a local tax professional for official filings.
