Tip Split Calculator
Last updated: November 14, 2026
Direct answer. Tip = Tip base × (Tip % ÷ 100). Total = Subtotal + Tax + Tip. Per person = Total ÷ People. On an $80 pre-tax subtotal, 20% tip, $0 tax, and 4 people, the tip is $16, the total is $96, and each person pays $24.
Tipping at U.S. restaurants is usually a percent of the food-and-drink subtotal, then the table splits the total. This calculator figures the tip, adds any tax you type, and divides the bill evenly. It does not replace the simpler one-person tip calculator already on this site; it adds a party split and an optional tax line.
Tip Split Calculator
Add a tip and split the bill evenly. In the United States, a tip is commonly calculated on the pre-tax subtotal; you can include tax in the tip base if that is how your table prefers to tip.
Result
Key takeaways
- By default the tip is calculated on the pre-tax subtotal, a common U.S. practice.
- You can optionally tip on subtotal plus tax by checking that box.
- $80 at 20% with 4 people and no tax is $16 tip and $24 each.
- People must be a whole number of at least 1.
How to use this calculator
- Enter the pre-tax subtotal in dollars and the tip percent.
- Enter how many people are splitting the bill evenly.
- Optionally enter the tax amount in dollars. Leave it at 0 or blank if tax is not being shared or is already unknown. Check the box only if you want the tip base to include tax.
The formula
The tip base is the pre-tax subtotal unless you include tax. Units are dollars for money, percent for the tip rate, and a count for people.
Worked examples
| People | Tax | Tip | Total | Per person |
|---|---|---|---|---|
| 4 | $0 | $16 | $96 | $24 |
| 2 | $0 | $16 | $96 | $48 |
| 4 | $6.40 | $16 (tip on subtotal) | $102.40 | $25.60 |
Tip base is 80. Tip is 16. Total is 96. Per person is 96 ÷ 4 = 24.
Tip stays 16. Total becomes 80 + 6.40 + 16 = 102.40. Per person is 25.60.
When this is useful in the United States
A group splitting a diner check in a U.S. city can agree on a tip percent, type the subtotal from the bill, and send each person the same amount over a payment app.
If the receipt already listed tax, enter that tax amount so the total matches the ticket, while still tipping on the pre-tax food total if that is the table’s rule.
This is an even split. It does not assign extra to the person who ordered a bottle of wine; do that adjustment after you have the even share.
Common mistakes
- Tipping on the post-tax total by accident when the table meant to tip on the subtotal. Leave the box unchecked to tip on the subtotal only.
- Entering the tax rate in the tax amount field. That field is dollars, not a percent.
- Using a people count of 0. The per-person amount would be undefined.
Service charges that a restaurant already added to the bill are not a tip you calculate here; if the ticket includes an automatic 18% service charge, do not also apply 20% unless you intend a further tip. Delivery-app fees and driver tips follow the app’s own screen, which may use a different base. The numbers on this page are a bill split, not tax or labor advice. Even splits are a convenience, not a rule of etiquette. A table can still agree on a different share after they see the even amount. Automatic gratuity for large parties, which some U.S. restaurants add as a service charge, is usually already in dollars on the ticket; adding another 20% on top is a further tip, not a correction of the service charge. If you are reimbursing someone who already paid the whole bill, include the tax they actually paid so your transfer matches their card statement. Payment apps that round to the cent may differ from this display by a penny when the per-person amount is a repeating decimal; the working shows the unrounded division first. If one person paid a parking fee or a bottle shop stop that was not on the restaurant ticket, settle that separately rather than burying it in the subtotal. The per-person result is then a true split of the shared meal, plus tax and tip as the table agreed.
Frequently asked questions
How much is 20% on an $80 bill split four ways?
The tip is $16 and the total is $96 if tax is 0, or $24 per person.
Should I tip before or after tax?
Many U.S. diners tip on the pre-tax subtotal. This calculator does that by default. Some people tip on the post-tax amount; check the box if that is your rule.
Does this replace the tip calculator already on the site?
No. /tip-calculator/ is unchanged. This page is a split-focused version with an optional tax line.
Can I enter a different tip for each person?
No. Everyone is assumed to pay the same share of a single total.
