18 Percent Tip Calculator

This page opens the tip calculator with 18% preset — enter the bill and the tip, total and per-person amounts appear at once. On a 100 bill, an 18% tip is 18, for a 118 total.

Eighteen percent has become the practical middle ground of American tipping — more generous than the old 15% baseline, less than the big-city 20% — and it is also the rate restaurants most often apply automatically as a service charge for large parties (usually six or more). Checking that auto-gratuity line against the bill takes two seconds here.

Mental math for 18% is genuinely awkward (double the bill, move the decimal point, subtract a tenth of that), which is exactly why this preset exists. Add the party size to split the total and tip evenly; everything recalculates live in your browser, in any currency.
