Tipping and splitting the check in the US

US checks do not include a tip, so you add it yourself. The common method is to apply the percentage to the pre-tax subtotal, divide by the number of people, and round each share up.

How to use this calculator

  1. Enter the pre-tax subtotal and the receipt's sales-tax rate, then choose whether the tip applies before or after tax.
  2. Set the service-appropriate percentage and check the receipt for any automatic gratuity before adding another tip.
  3. Choose the number of people and use round-up only after deciding how the group will handle the extra cents.

How to read the result

The result separates tax, tip, total bill and per-person share so the assumptions remain visible. Tipping on the after-tax total produces a slightly larger tip than tipping on the subtotal.

What this estimate does not capture

Local customs and service charges vary. A service fee is not always distributed to staff in the same way as a voluntary gratuity, so ask the business when the receipt is unclear.

Methodology, assumptions & limits

Inputs are applied directly to standard finance formulas with monthly compounding where relevant. Results are estimates in the selected currency; they do not include every tax, fee, benefit, market event or local rule. Try a conservative and an optimistic case before making a decision.

Frequently asked questions

What percentage should I tip?

18–22% at full-service restaurants, 10–15% at counter service, $1–2 per drink at a bar.

Do I tip on the pre-tax amount?

Usually yes — tip on the subtotal before sales tax. This calculator does the same.

When is gratuity added automatically?

Many restaurants add an 18–20% gratuity for parties of six or more. In that case no extra tip is expected.

How do I tip when paying by card?

Write the tip on the receipt's tip line and total it yourself. The round-up toggle makes the per-person number easy.
