Is this the same as US sales tax?

The math is the same for a single percentage tax. Rates and rules differ by country and state.

Which VAT rate should I use?

Use the rate that applies to the goods or service. Common examples are 5%, 10%, 19%, and 20%.

Choose add or extract, then enter the amount and rate. Adding multiplies the net amount. Extracting divides a gross amount by 1 + rate.

Add: gross = net × (1 + rate). Extract: net = gross ÷ (1 + rate). VAT = gross − net.

Adding 20% VAT to $100 gives $20 tax and $120 gross. Extracting 20% from $120 returns $100 net.
