Split expenses calculator.
Put in an amount and who is sharing it, then choose how it should be divided: equally, in proportion to what people earn, or by any weights you agree. Runs in your browser, remembers inputs on this device, and it uses the same split engine as the app so the parts always add back to the total.
Links include entered names, amounts and any incomes. Anyone with the link can read them. Inputs are saved on this device; clear them here when finished.
Sharing it
Each person pays
- You50.0%$600.00
- Them50.0%$600.00
Adds back to $1,200.00 exactly. When an amount does not divide evenly, the spare cents go to whoever rounding shortchanged most, rather than being dropped.
If your case needs more than an amount
This page divides one amount. These divide the situations it cannot: several expenses, different payers, rooms of different sizes, a bill with tip and tax on it.
Common questions
How do you calculate splitting expenses?
Divide the amount by the number of people if everyone is getting the same thing. If they are not, give each person a weight and divide in proportion to it: income for household bills, nights stayed for a trip, room size for rent. The share is that person’s weight divided by the sum of all the weights, times the total.
What is the fairest way to split expenses?
There is no single answer, because fair depends on what people are getting. An even split is fairest when everyone benefits equally and earns similarly. Splitting by income is fairer when the incomes are far apart, because the same dollar amount is a much bigger sacrifice for the lower earner. Splitting by use is fairest when one person is getting more: the bigger bedroom, the extra nights, the car nobody else drives.
How do you split expenses when one person earns more?
In proportion to income. Add both incomes, work out each person’s share of that combined figure, and apply those percentages to the bill. On $4,200 and $3,300 a month the shares are 56% and 44%, so $1,200 of rent becomes $672 and $528. Both people are then paying the same proportion of what they earn.
How do you split an amount that does not divide evenly?
Give the spare cents to specific people rather than rounding each share. $100 between three is $33.34, $33.33 and $33.33: one person carries the extra cent and the parts add back to exactly $100. Rounding every share to $33.34 would collect $100.02, which is a real, if tiny, overcharge.
Is this expense splitting calculator free?
Yes, and there is no signup, no email and no account. It runs entirely in your browser, so the amounts you type are never sent anywhere. It uses the same split engine as the Halvy app, so the numbers match to the cent.
What if more than two people are splitting it?
Add as many people as you need; the arithmetic is the same. If several people also paid for different things, a plain split is the wrong tool: what you want then is who owes who, which nets the payments off against each other and gives you the shortest list of transfers.
If you are splitting the same things every month
A calculator is the right tool for one amount. When the expenses keep arriving, what you actually want is something that remembers the method you agreed and keeps a running total. Halvy splits by income for free, has no ads on any tier, and never asks to connect to a bank.
