Tip Calculator and Bill Splitter
Work out the tip, then split the bill evenly or by what each person actually ordered.
Before tax and before any tip.
Leave at 0 if tax is already in the total.
What each person ordered
Tax and tip are shared in proportion to what each person spent.

Who pays what
Everything here runs on your device. Nothing you enter is uploaded or stored.
A tip calculator that also handles the harder half of the problem: dividing the result between people who did not all order the same thing. Enter the bill, pick a tip percentage, set the headcount, and you get the tip, the grand total, and what each person owes — with the cents worked out so the numbers actually reconcile.
How to use it
- Enter the bill total exactly as printed on the receipt, before tax and before any tip.
- Set the tip with the slider, or press one of the presets for 15, 18, 20 or 25 per cent.
- If your receipt shows tax separately, enter the tax percentage and choose whether the tip applies before or after it.
- Enter how many people are paying. For an even split, that is all you need.
- If people ordered very differently, switch to per-person amounts and enter each person’s items.

The penny that goes missing
Most bill splitters have a rounding bug, and it is easy to miss because it is only ever a cent or two.
Take a $100.00 total split three ways. Divide and round to the nearest cent and each person pays $33.33. Three times $33.33 is $99.99, so the table is a penny short and somebody covers it without noticing. Split $50.00 four ways after an 18% tip and the shortfall can run to three or four cents.
The fix is to work in whole cents rather than in decimal dollars. This calculator converts the total to an integer number of cents, divides by the headcount, and then distributes the remainder one cent at a time from the first person onward. Three people on $100.00 get $33.34, $33.33 and $33.33 — which sums to exactly $100.00. When that happens the tool says so under the breakdown, so nobody thinks the uneven figures are a mistake.
The same principle applies to per-person mode, where tax and tip are apportioned by what each person actually spent. Someone who ordered a $12 salad should not pay the same share of the tip as someone who ordered a $60 steak, and proportional apportionment is the only split that stays defensible when the table checks it.
What it does not do
It will not read a receipt photo, and it does not know your local tax rate — you have to enter it. It handles a maximum of twenty people, because past that a spreadsheet is the better tool. Tipping norms vary enormously by country and by venue type, and this calculator has no opinion on what you should pay: the presets reflect common US table-service practice and nothing more.

Tipping percentages by service type
| Situation | Common US range | Notes |
|---|---|---|
| Restaurant, table service | 18–20% | 25% for exceptional service |
| Counter service, coffee | 0–10% | Often just loose change |
| Bar, per drink | $1–2 per drink | Or 15–20% on a tab |
| Food delivery | 15–20% | Minimum $3–5 on small orders |
| Taxi or rideshare | 10–15% | Round up to a clean figure |
| Hairdresser, barber | 15–20% | On the pre-tax total |
Tip on a $100 bill
| Tip | Amount | Total | Split 2 ways | Split 4 ways |
|---|---|---|---|---|
| 15% | $15.00 | $115.00 | $57.50 | $28.75 |
| 18% | $18.00 | $118.00 | $59.00 | $29.50 |
| 20% | $20.00 | $120.00 | $60.00 | $30.00 |
| 25% | $25.00 | $125.00 | $62.50 | $31.25 |
Questions
Should you tip before or after tax?
In the United States the convention is to tip on the pre-tax subtotal, because tax is not a service the restaurant provided. Tipping on the taxed total is not wrong, just slightly more generous. On a $100 bill with 8% tax, the difference at 20% is $1.60.
Why do the individual shares differ by a penny?
Because most totals do not divide evenly. Three people splitting $100 cannot each pay $33.33 — that collects $99.99. This calculator hands the leftover cents out one at a time, so the shares always sum to the exact total.
How much should I tip?
In US restaurants 18-20% is standard for table service, 15% for adequate service, and 25% for exceptional. Counter service, takeaway and bars follow different norms, and in much of Europe and Japan service is included and tipping is not expected.
Can I split a bill when everyone ordered different things?
Yes. Switch to per-person amounts and enter what each person's items came to. Tax and tip are then divided in proportion to what each person spent, rather than equally.
