FAQ

How do I calculate VAT inclusive and exclusive amounts?

Pass the base amount and VAT rate (as percentage). The tool returns both VAT-inclusive total and VAT-exclusive amount, plus the VAT amount itself.

What VAT rates does the calculator support?

Any custom VAT rate as a percentage. Common rates like 20% (UK), 19% (Germany), or 10% (reduced rates) all work. No predefined rate limits.

Can MCP tools in Cursor automatically calculate VAT for invoices?

Yes, AI agents can call this tool to compute VAT on invoice line items, handling multiple rates and currencies in automated accounting workflows.

Does the VAT calculator handle reverse calculations?

The tool calculates from base amounts. For reverse VAT (finding pre-tax amount from VAT-inclusive total), divide the inclusive amount by (1 + VAT rate).

What's the difference between VAT inclusive and exclusive pricing?

VAT exclusive shows the base price before tax. VAT inclusive shows the final price including tax. This tool computes both from your base amount.
