How this calculator works
Tip = bill × tip percentage; total = bill + tip; each person pays the total divided by the number splitting it, all in exact cents.
Enter the bill amount you want to tip on (pre-tax or post-tax). Rounding each share to the cent means the shares sum to the total within a penny.
Formula
Tip = Bill × rate
Total = Bill + Tip
Per person = Total ÷ people- Bill
- Pre-tax amount, by the usual convention
- rate
- Tip percentage, as a decimal
Convention varies on whether to tip on the pre-tax or post-tax total; both are defensible and the difference is small. Worth checking whether a service charge has already been added — tipping on top of one is paying twice.
What this assumes
- Tip calculated on the pre-tax amount unless you enter the tax-inclusive total — convention varies and both are defensible.
- Service charges already added to the bill are not detected, and tipping on top of one is double payment.
- Splitting is even unless you enter otherwise.
What changes this number
- Pre-tax or post-tax base
- A small difference on a large bill, and the most common source of disagreement at the table.
- Existing service charge
- Worth checking before adding a tip — many bills already include one.
- Rounding
- Rounding up is the usual convention and the difference rarely matters; this shows the exact figure either way.

Frequently asked questions
How much should I tip?
In the US, 15% is a standard restaurant tip, with 18–20% for good service; 20%+ rewards excellent service. Many people tip on the pre-tax amount, though tipping on the total is common too. For counter service, delivery, and other situations, norms vary.
How do I split a bill with tip evenly?
Add the tip to the bill, then divide the total by the number of people. This calculator does it in one step — enter the bill, tip percentage, and group size to see exactly what each person owes, tip included.
Should I tip on the pre-tax or post-tax amount?
Either is acceptable; tipping on the pre-tax subtotal is technically correct since tax isn't part of the service. The difference is usually small. Enter whichever amount you prefer as the bill.
