| Inputs | Answer |
|---|---|
| 50, 8 | $50.00 plus 8% tax is $54.00 (tax $4.00). |
| 120, 6.5 | $120.00 plus 6.5% tax is $127.80 (tax $7.80). |
| 19.99, 7 | $19.99 plus 7% tax is $21.39 (tax $1.40). |
How to use it
Tax = price × rate ÷ 100, and the total is the price plus the tax. $50 at 8% is $4 tax, $54 in total.
Rates differ by place and change, so the calculator uses the rate you type; check your state, city or tax authority for the current rate. It does not look a rate up for you.
