How to calculate
Add a tax rate to a before-tax price.
Tax = price × rate ÷ 100; total = price + tax
Worked example
Before-tax price: 100; Tax rate (%): 5.
Total including tax: 105 ; Tax amount: 5 .

Understanding the result

Frequently asked questions
Does MyCalCute determine my tax rate?
No. Rates and taxable items vary by jurisdiction. Enter the rate that applies to your transaction.
Can I recover tax from an inclusive price?
Divide the inclusive amount by (1 + rate/100) to find the pre-tax amount. This tool instead adds tax to a pre-tax input.
