At 8.25%, a 100 item has 8.25 tax and a total of 108.25. A 19.99 item at 7% has 1.40 tax for a total of 21.39, and a 49.50 purchase at 10% has 4.95 tax, totalling 54.45.
The tax is the pre-tax price multiplied by the rate and divided by 100, and the total is the price plus that tax. Full precision is kept during the calculation and only the displayed figures are rounded to two decimals: 19.99 at 7% is exactly 1.3993 in tax, shown as 1.40.
Enter the combined rate that applies where the sale takes place, because state, county and city taxes are often added together. The tool does not look up rates by location and does not know about exemptions or reduced rates. Enter 0% for an exempt item, so 250 stays 250.
Use the price that excludes tax and the full percentage that applies to the purchase. At 8.25%, a 100 item has 8.25 tax and a total of 108.25. In places where state, county and city taxes are added together, enter the combined rate rather than just one component. The calculator does not look up rates by location, so check the rate on a recent receipt or with the tax authority for the address where the sale takes place.
A 19.99 item at 7% has an exact tax of 1.3993, displayed as 1.40, for a total of 21.39. Retailers usually round tax on the whole invoice or on each line, and the method can change the final cent when many items are bought together. A 49.50 purchase at 10% has exactly 4.95 tax, totalling 54.45. If your receipt differs by one cent, the store’s rounding rule is the usual reason rather than a different rate.
This tool adds tax to a pre-tax amount. To find the price before tax from a total, divide by one plus the rate: 108.25 ÷ 1.0825 = 100. The VAT Calculator can do that reverse calculation directly. Enter 0% for exempt items, so 250 stays 250. Where items in one basket are taxed at different rates, such as groceries and prepared food, calculate each group separately and add the totals together.
| Input | Result |
|---|---|
100 · 8.25% | 108.25 (8.25) |
19.99 · 7% | 21.39 (1.4) |
49.5 · 10% | 54.45 (4.95) |
250 · 0% | 250 (0) |
Divide the total by one plus the rate rather than subtracting the percentage: 108.25 ÷ 1.0825 = 100. The VAT Calculator does this reverse calculation for you. Subtracting 8.25% from 108.25 would give a different, incorrect figure, because the tax was charged on the smaller pre-tax amount.
Rounding rules differ. Stores may round the tax on each line or once on the whole invoice, and the two methods can disagree by a cent when several items are bought together. This tool rounds only the displayed result, so a small difference usually reflects the store’s method rather than a different rate.
The arithmetic is the same for adding any percentage, so it works for VAT or GST when tax is added to a net price. For a basket taxed at different rates, such as groceries and prepared food, calculate each group separately and add the totals together.
