Tip Calculator
Calculate the tip and split the bill evenly or unevenly across the table.
About Tip Calculator
The tip is a percentage of the pre-tip bill. Add it to the bill for the total, then divide by the number of people to see everyone's fair share.
Formula
Tip = Bill × (tip% ÷ 100) Total = Bill + Tip Per person = Total ÷ people
- B
- Pre-tip bill amount
- r
- Tip percentage
- n
- Number of people splitting the bill
Worked example
With the default values below, Tip Calculator returns Total (with tip) of $94.40. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits
- The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

The ten seconds before the card machine arrives
The bill lands, someone has to work out the tip, and four people are waiting. This calculator takes the bill, the tip percentage and the number of people, then shows the total with tip, the tip itself, what each person pays, and each person's share of the tip — so nobody has to trust mental arithmetic after dinner.
The arithmetic
Tip = Bill × (tip% ÷ 100)
Total = Bill + Tip
Each person pays = Total ÷ people
The tip is a percentage of the Bill Amount you typed, so whatever goes in that field is what gets tipped on. Nothing is added or assumed beyond it.
The default bill
Bill 80, tip 18%, split between 2:
- Tip: 80 × 0.18 = 14.40
- Total: 80 + 14.40 = 94.40
- Each person pays: 94.40 ÷ 2 = 47.20
- Tip per person: 14.40 ÷ 2 = 7.20
Changing only the percentage on that same 80 bill:
| Tip % | Tip | Total | Each of 2 |
|---|---|---|---|
| 15 | 12.00 | 92.00 | 46.00 |
| 18 | 14.40 | 94.40 | 47.20 |
| 20 | 16.00 | 96.00 | 48.00 |
| 25 | 20.00 | 100.00 | 50.00 |
The whole range from a modest 15% to a generous 25% is 8.00 on an 80 bill — 4.00 each. Useful perspective when a table starts debating it.
Working backwards to a round number
Because the steps are simple, you can aim at a target. Want the two of you to pay exactly 50 each on that 80 bill? That is a 100 total, so the tip must be 20, and 20 ÷ 80 = 25%. Nudging the Tip Percentage field until Each Person Pays lands on a clean figure is often faster than doing it on paper.
Where it gets awkward
- Splits that do not divide evenly. 94.40 across 3 people is 31.4667 each. Round up to 31.50 and the table covers the bill with 0.10 to spare; round down and you are short.
- Pre-tax or post-tax. Tipping 18% on an 80 bill is 14.40; tipping on the same bill after 8.25% sales tax, so 86.60, is 15.59. The 1.19 difference is small, but enter whichever base you intend to tip on — the calculator tips on exactly what you type.
- Unequal orders. The split is strictly even. If one person had a 60 steak and another a 12 salad, split the bill by what each ordered first, then apply the tip percentage to each share.
- A service charge already on the bill. Many bills, especially outside the US, include 10% or more as a service charge or in the menu prices. Check before adding a second tip.
There is no currency setting, so the figures work for any currency. To see tax added to a pre-tax total, use the sales tax calculator; for the percentage mechanics on their own, the percentage calculator; and for a discounted bill, the discount calculator.
Frequently Asked Questions
Should I tip on the pre-tax or post-tax total?
Customarily tips are based on the pre-tax bill, but practices vary. Enter whichever amount you prefer to tip on as the bill amount.
What's a standard tip?
In the U.S., 15–20% is common for sit-down restaurant service, with 18% a frequent default. Norms differ widely by country.
One person had drinks and the others didn't — can I still use this?
Split Between divides the total evenly, so handle the uneven part first. Work out each person's own subtotal, then run the tip percentage on that subtotal with Split Between set to 1. On an 80 bill at 18%, someone whose share was 30 owes 30 × 1.18 = 35.40.
What tip percentage should I enter to make each person's share a round number?
Set the target first, then solve. For 50 each between 2 people on an 80 bill, the total must be 100, so the tip is 20 and 20 ÷ 80 = 25%. Entering 25 confirms it. Adjusting the percentage a point at a time until Each Person Pays looks clean works just as well.
Should I round the tip or the per-person amount?
Round the per-person figure up, because that is the number people actually hand over. 94.40 split three ways is 31.4667 each; at 31.50 each the table puts in 94.50 and the bill is covered. Rounding the tip first then dividing often leaves the total a few cents short.
Does the Tip per Person figure include the food, or just the tip?
Just the tip. On the default bill it is 7.20, which is 14.40 ÷ 2, while Each Person Pays is 47.20 and covers food plus tip. Tip per Person is handy when the meal is being billed to a company but the tip is coming out of pockets at the table.
