Free Bill SplitterSplit any bill in seconds.
To split a bill, add tip and tax to the total and divide it by the number of people — or by each person’s share if they didn’t all owe the same. The calculator below does that instantly. It is free, needs no account, and works for restaurant checks, rent, trips, fuel, and any other shared cost.
Everyone pays the same.
Enter a bill total to see the split.

How to split a bill
- 1
Enter the bill total
Type the amount before tip and tax, and pick your currency. Nothing is sent anywhere — the maths runs in your browser.
- 2
Add everyone splitting it
Add a row per person and name them if you want the result to read cleanly when you share it.
- 3
Choose how to split
Evenly, by shares, by percentage, or by exactly what each person ordered. Tip and tax follow whichever you pick.
- 4
Copy the result and settle up
Tap “Copy the split” to paste each person’s exact amount into your group chat, then settle over UPI, Venmo, or any payment app.
Four ways to split, and when each one is fair
Most arguments about a bill aren’t about arithmetic. They’re about which method to use. Here is the honest case for each.
Evenly
The default, and right more often than people admit. If the difference between the biggest and smallest order is under about 15%, itemising costs more social capital than it saves anyone money. Use it for group dinners where everyone ate a main, shared taxis, and standing household bills.
By shares
Use when people have unequal claims on the same thing. The bigger bedroom gets 1.5 shares of the rent; the couple sharing a hotel room gets 2 shares; the person who joined the trip for three of five nights gets 0.6. Shares stay readable months later in a way that raw percentages don’t.
By percent
Use when the ratio is the agreement itself. The most common case is splitting household costs in proportion to income: if one person earns 60% of the household total, they pay 60% of the rent. That is a different fairness claim than “we each pay half”, and it is worth saying out loud before you set it up.
By what they ordered
Use when the gap is genuinely large — one person had a steak and three drinks, another had soup. Enter each person’s items and let tip, tax, and service charge ride along in proportion. Splitting those evenly on top of uneven food is the mistake most people make here.
The awkward cases
One person doesn’t drink and the table ordered three bottles of wine
Pull the alcohol out as its own line, split it between the drinkers, and split the food evenly. This is the single most common source of quiet resentment about a split bill, and it takes about twenty seconds to fix. In the calculator: enter the food total, split evenly, then run the drinks as a second split between fewer people.
Someone arrived halfway through
Give them a partial share rather than a full one — 0.5 shares for arriving at the halfway point of a dinner, or nights-stayed ÷ total-nights for a trip. Use “By shares” and the fractions do the work.
One person paid the whole bill on their card
The split is the same; what changes is who owes whom. Everyone except the payer owes their share to the payer. Copy the split into the chat, tag the payer, and settle in one round — or let FamZam track it so nobody has to remember.
The number won’t divide cleanly
Don’t round each share up — that quietly overcharges the group. This calculator distributes the leftover cents one at a time to whoever was rounded down hardest, so the shares always add back to the exact total.
A service charge was already added
Check whether it is already in the total on the bill. If it is, enter that grand total as the bill amount and leave tip at 0 — otherwise you tip twice. If you want to add something on top, most people add 5% or a round-up, not a full second tip.
You’re splitting with someone who never pays back
A calculator can’t fix this, and neither can an app, but a shared running balance that both people can see removes the “I thought you covered that one” defence. That is most of the value of tracking it.
Bill splitting FAQ
How do you split a bill between friends?
Add up the bill, add tip and tax, then divide the total by the number of people. If everyone ate or used roughly the same amount, an even split is fairest and fastest. If one person had significantly more, split by what each person ordered and share tip and tax in proportion to those amounts. This calculator does both — pick “Evenly” or “By what they ordered”.
Is this bill splitter free, and do I need an account?
It is completely free and there is no account, no signup, and no email required. The calculator runs entirely in your browser, so your amounts never leave your device. FamZam, the app behind it, is also free with no ads and no subscription.
Do you add tip before or after tax?
Convention in the US is to tip on the pre-tax subtotal, which is what this calculator does — tip and tax are both calculated from the bill amount you enter, not stacked on each other. Tipping on the post-tax total is more generous and adds roughly the tax rate multiplied by the tip rate, usually a few cents per person.
How do you split a bill when one person ordered much more?
Switch the calculator to “By what they ordered” and enter each person’s own items. Tip, tax, and any service charge are then shared in proportion to what each person spent, which is fairer than splitting those evenly on top of uneven food costs.
How do you split a bill unevenly, like rent by room size?
Use “By shares”. Give each person a number — someone in the larger bedroom gets 1.5 shares while the others get 1, for example — and the calculator divides the total in that ratio. Use “By percent” instead when you have already agreed on exact percentages, such as splitting in proportion to income.
Do the amounts always add up to the total?
Yes. When a total does not divide cleanly, the leftover cents are handed to the people whose share was rounded down the most, so the individual amounts always sum back to the exact bill total. Three people splitting 10.00 get 3.34, 3.33, and 3.33.
Can I split a bill in a different currency?
Yes — pick any of the ten currencies in the dropdown, including rupees, dollars, euros, and pounds. For a trip where you spend in several currencies, the FamZam app converts each expense at real-time rates and keeps one running balance for the group.
What if I want to keep track of the split afterwards?
A calculator answers one bill. FamZam remembers the group, tracks every expense over time, works out who owes whom, and settles up in the fewest possible payments — free, with no ads, no subscription, and no daily expense limit.
