Sales Tax Calculator
The calculator multiplies an amount by a sales-tax rate. 100 at 6% in Florida gives 6.00 tax and 106.00 total. After you choose a state, the rate field shows the table value. You can type your own. When you enter a total, the calculator extracts the tax. This is not VAT.
Polish VAT is on VAT net/gross. Income tax is on the income tax page.
Result
Enter an amount and a rate. The result will appear here.
How it works
The calculator multiplies the amount by the state rate and divides by 100. 100 at 6% in Florida gives 6.00 tax and 106.00 total.
50 at 7.25% in California gives 3.63 tax and 53.63 total, because 3.625 rounds to two decimals.
80 in Oregon gives 0.00 tax, because the state rate is 0%. Alaska, Delaware, Montana, and New Hampshire are also 0% at the state level.
The state table only suggests a rate. You type your own percent, for example from a register, in the rate field. From a total of 106 at 6% the tax is 6.00 and the before-tax amount is 100.00. There is no ZIP lookup here.
This is not VAT. VAT converts net or gross on a separate page.
A comma and a period give the same fraction.
Formula
tax = amount × rate / 100, before = total / (1 + rate / 100)
rate is the percent you enter or the one the state table suggests. A ZIP is not in this formula.
