How it works
Adding tax multiplies the net price by the rate and adds it on. Removing tax works backwards from a tax-inclusive price to find the original net amount.
Gross = Net × (1 + rate); Net = Gross ÷ (1 + rate)Frequently asked questions
How do I add tax to a price?
Multiply the net price by the tax rate to get the tax amount, then add it to the net price for the gross (tax-inclusive) total.
How do I remove tax from a gross price?
Divide the gross price by (1 plus the rate as a decimal) to get the net price; the difference is the tax included.
