Split Bill Calculator

Add the tax to the bill subtotal first, then calculate the tip on the amount including tax. Divide the grand total (bill + tax + tip) by the number of people. For a $100 bill with 8% tax and 18% tip: $100 + $8 tax = $108, plus $19.44 tip = $127.44 total. Split 4 ways, that is $31.86 per person.

Etiquette experts are split on this. Tipping on the pre-tax amount is technically correct, but tipping on the post-tax total is more common and simpler to calculate. The difference is small: on a $100 bill with 8% tax, tipping 20% pre-tax is $20 while tipping 20% post-tax is $21.60. This calculator tips on the post-tax amount for simplicity.

15% is considered the minimum for adequate service in the US. 18 to 20% is standard for good service. 25% or more is generous and appropriate for exceptional service. For takeout, 10 to 15% is customary. For delivery, 15 to 20% is standard. Some countries like Japan and South Korea do not have a tipping culture.

For uneven splits, each person calculates their share of the food subtotal, then adds their proportional share of tax and tip. For example, if the total bill is $200 and you ordered $60 worth, your share is 30% of the tax and tip. This calculator handles equal splits; for uneven splits, calculate each person's food percentage and apply it to the total.

The combined state and local sales tax rate averages 7.12% across the US. Rates range from 0% (Delaware, Montana, New Hampshire, Oregon) to over 10% in parts of Louisiana, Tennessee, and Arkansas. The five states with no sales tax save diners 5 to 10% on restaurant bills. Most restaurants include tax separately on the bill.
