Tipping guide
Most people calculate a restaurant tip before tax because sales tax is not part of the service price. Tipping after tax is simpler and slightly more generous. USTipCalc lets you compare both methods before you pay.
Use the pre-tax subtotal if you want to tip only on the service price. Use the after-tax total if you want the faster and slightly more generous method.

Restaurant receipt tip
Many diners use the pre-tax subtotal for a restaurant tip because it matches the cost of the meal or service before government sales tax is added. This is easy when the receipt clearly shows a subtotal line.
Payment screen tip
Some card readers and checkout screens may show suggested tips based on the after-tax total or another amount. If the suggested amount seems high, compare it with the subtotal using the calculator.
This example shows why the difference is usually small, but still useful to understand.
| Method | Tip basis | Tip | Total |
|---|---|---|---|
| Tip before tax | $50.00 | $10.00 | $64.00 |
| Tip after tax | $54.00 | $10.80 | $64.80 |
Pre-tax method
Pre-tax tipping is helpful when you want the gratuity to be based only on the service price. It is common for restaurant checks because sales tax is added by the government, not by the server.
Post-tax method
After-tax tipping is easier when you only see the final total or when a payment screen suggests tips from the after-tax amount. It usually adds a small amount more than pre-tax tipping.
Best practical answer
For a normal restaurant check, pre-tax tipping is a clear and common method. For a quick checkout or delivery order, after-tax tipping may be easier because the total is already shown. Either way, the important point is to know which number the percentage is based on before you pay or split the bill.
