Bill split calculator
Split any bill four ways: evenly, by exact amounts, by percentage, or by shares.
Enter the bill total to see the split.
Enter the total, say how many people are splitting it, and pick a method. The result updates as you type, and every split is checked so the individual amounts add up to the original total exactly — not a cent more or less.
Most splits are even. The interesting ones aren't: one person had the expensive entrée, two people are sharing a room, someone is covering a friend until payday. The four methods below cover those without needing a spreadsheet.
Which method to use
The method matters more than the arithmetic. Picking the wrong one is how splits end up feeling unfair even when the math is right.
- Evenly — everyone pays the same. Right for a shared meal, a taxi, or a group gift where nobody consumed noticeably more.
- By exact amounts — you already know what each person owes, and you want to confirm it adds up. Right for a receipt where each line is clearly one person's.
- By percentage — one person covers 60%, another 40%. Right for couples splitting proportionally, or a business expense split between two budgets.
- By shares — express the ratio instead of the percentage: 2:1:1, or one share per person plus an extra for the couple in the big room. Easier than percentages when the ratio is obvious but the percentage isn't a round number.
Where the leftover cent goes
Three people splitting $100.00 is the classic problem: $33.33 each leaves a cent unaccounted for. A calculator that rounds each share independently produces $33.33 × 3 = $99.99 and quietly loses a penny. Over a long trip with dozens of expenses, those pennies drift into a balance nobody can reconcile.
This calculator assigns the remainder rather than dropping it. One person pays $33.34, the other two pay $33.33, and the parts sum to exactly $100.00. The same rule applies to percentage and share splits, where rounding errors are larger and more common.
Currencies with no decimal place
Yen and won have no minor unit, so a three-way split of ¥10,000 is ¥3,334 / ¥3,333 / ¥3,333 rather than anything with a decimal point. Choosing the currency changes both the rounding and the formatting, which matters if you are splitting a bill abroad and want a figure you can actually hand over in cash.
Questions
- Is this bill split calculator free?
- Yes. It calculates in your browser, needs no account, and has no usage limit. Nothing is stored. The one exception is the share link, which encodes your figures into the URL — so only send it to people you would show the numbers to.
- How do I split a bill unevenly?
- Use exact amounts if you already know each person's figure, percentages if you think in percentages, or shares if you think in ratios. All three guarantee the parts sum to the total.
- What happens to the extra cent when the split isn't clean?
- It is assigned to the first person or people in the list rather than being rounded away. That keeps the sum of the shares exactly equal to the bill.
- Can I split a bill between more than a few people?
- Yes, up to 24 people. Past that a running balance across many expenses is usually more useful than a single split, which is what the Make It Even app does.
- Does it handle tax and tip?
- For a bill that already includes tax, just enter the final total. If you want to add a tip and see per-person amounts, use the tip calculator, which lets you tip on the pre-tax subtotal or the post-tax total.
- Can I save the split or send it to someone?
- Copy the result link and the calculator reopens with the same numbers for whoever you send it to. To keep a running total across many bills, create a free Make It Even group instead.
When one calculation isn’t enough
A calculator answers a single question. Make It Even keeps the answer current: add expenses as they happen, split each one however it needs to be split, and everyone sees the running balance. It handles multiple currencies using the exchange rate from each expense’s own date, so old totals never drift.
