Add your local tax

The chart above is tip-only. If your bill is $100 before tax, enter your tax rate below and the calculator adds it — and lets you choose whether the tip is figured on the pre-tax subtotal (the conventional base) or on the after-tax total.

Tip is calculated on

The long-standing etiquette convention is to tip on the pre-tax subtotal — the tax goes to the government, not to your server. Tipping on the post-tax total is also common and a little more generous; this switch changes the base, nothing else.

How the chart is calculated

Tip = bill × rate, rounded half-up to the nearest cent; total = bill + tip. The split amounts are penny-exact: when the total does not divide evenly, leftover cents go one each to the first shares so the parts always sum to the total. For other amounts, see tip on $50, tip on $75, tip on $100 and tip on $200 — or run any bill through the tip calculator.

Frequently asked questions

What is a good tip on a $100 bill?
For sit-down restaurant service in the US, 18–20% is the usual range for good service — that is $18.00 to $20.00 on a $100 bill. For takeout and counter service, less or nothing is customary; see the tipping guide for the ranges by situation.
Is tax included in these numbers?
No. The chart is computed on the $100 amount alone. Use the calculator above with your local tax rate if you want tax added, and remember the tip convention is to figure the percentage on the pre-tax subtotal.
