Enter the total and the number of people to see each share.
Splitting a bill fairly, down to the last coin
Dividing a restaurant or group bill sounds like simple division, but three things make it fiddly in practice: the tip, rounding to a payable amount, and the leftover cents or won that never divide cleanly. This calculator handles all three so that everyone pays a clean number and the total still adds up.
How each share is worked out
The core formula is share = total × (1 + tip%) ÷ people. The tip is applied to the whole bill first, then the grand total is split. If you choose to round up each share, the tool rounds every person's amount to the next 1, 10, 100, or 1000 unit — which slightly overshoots the bill and leaves a small buffer rather than coming up short at the till.
What rounding does to the total
| Round up to | Each pays | Collected (×4) | Buffer |
|---|---|---|---|
| Exact | 24,927.50 | 99,710 | 0 |
| Nearest 100 | 25,000 | 100,000 | 290 |
| Nearest 1,000 | 25,000 | 100,000 | 290 |
In this example the 100 and 1000 steps happen to match, because 24,927.50 rounds up to 25,000 either way; with a larger remainder they would diverge.
Who pays the leftover?
When a share does not divide evenly, someone has to absorb the fraction. Rounding up spreads the cost so the group slightly overpays and the difference sits as a buffer — often enough to cover the coins a card reader will not dispense. If you would rather match the bill to the exact cent, keep the split on Exact and let one person cover the odd remainder, or ask the venue to split the payment across cards. Tipping norms differ by country too: around 15 to 20 percent is common in the United States, while many countries fold service into the price and round up only lightly.
Common mistakes and what this tool does not do
- Tipping on the wrong base: some people tip on the pre-tax amount, others on the total. This tool applies the percentage to whatever total you enter — decide which base you mean before typing it.
- Rounding down: split a bill down and the group comes up short. Rounding up is the safe default for shared payment.
- Uneven orders: this is an even split. If one person had the steak and another only a salad, an equal share is not fair — you would itemise instead.

Frequently asked questions
What if the bill doesn't split evenly?
Pick a round-up amount — nearest 1, 10, 100, or 1,000 — and this split bill calculator rounds every share up to a clean number. The little bit extra that gets collected shows up as the rounding surplus, which the organizer usually keeps or covers. Leave it on "Exact" if you'd rather split to the cent.
Does it include tip and tax?
Tip is optional: tap a preset (10 / 15 / 18 / 20%) or type your own, and it's added before the bill splitter divides. For tax, fold it into the total amount (or into the tip field), then split — one even share per person.
Even split or itemized Dutch pay?
This tool does one thing fast: an even split where everyone pays the same share. Itemized or weighted Dutch pay, where each person owes a different amount, is out of scope by design.
Is my amount sent to a server?
No. Every calculation runs locally in your browser. Nothing you type is uploaded, saved, or shared — no account, no tracking, works offline.
How do I use the copy button?
Tap "Copy message" to grab a ready-to-send line like "Each of 4 pays 21,200 (total 84,800)" and paste it straight into your group chat. You can also tap any single figure — each share, total, or surplus — to copy just that number.
