FAQ
VAT and GST calculator questions
How do I add VAT or GST to a net price?
Choose the tax-exclusive mode. The calculator multiplies the net amount by the selected rate and adds the tax to produce the gross amount.
How do I remove VAT or GST from an inclusive price?
Choose the tax-inclusive mode. The calculator divides the gross amount by one plus the tax rate to recover the net amount and included tax.
Can I use a custom VAT or GST rate?
Yes. Country presets provide common rates, but the percentage remains editable for reduced rates, historic transactions or other tax systems.
Can I calculate a mixed-rate invoice?
Yes. Add multiple lines with different rates and inclusive or exclusive amounts. The workspace totals net value, VAT or GST, and gross value.
Are the country rates guaranteed for every product or service?
No. Standard and common reduced rates are starting points. Product classification, exemptions, place-of-supply rules and special territories can change the correct treatment.
