How VAT calculations work

VAT is usually calculated from a net price by multiplying the amount by the VAT rate and adding the result back on top. That gives the final gross price a customer pays.

Removing VAT is slightly different. You do not take a simple percentage of the gross price. Instead, you extract the VAT portion using the VAT fraction method, which correctly separates the tax from the tax-inclusive total.

When to add VAT vs remove VAT

Use Add VAT when you are starting from an ex-VAT or net figure.
Use Remove VAT when the amount already includes VAT and you want the underlying net value.

Why country presets matter

VAT and GST rates vary by country, and some countries use reduced or zero rates for specific categories. Presets help you move quickly while still allowing manual rate changes when needed.

Frequently asked questions

How do I add VAT to a net price?

Multiply the net price by the VAT rate to get the VAT amount, then add that tax amount to the net price to get the gross price.

How do I remove VAT from a gross price?

Use the VAT fraction method: gross price multiplied by rate divided by 100 plus rate. This extracts only the tax portion correctly.

What is the difference between VAT and GST?

The names differ by market, but the calculation structure is usually the same for price-add and price-remove workflows. This tool supports both VAT and GST-style setups.

Can I use a custom VAT rate?

Yes. You can use the country presets or type your own rate manually when you need a custom setup.
