Small calculators for shared money, free to use and running entirely in your browser. They use the same split engine as the Halvy app, so the numbers match to the cent.
Split expenses calculator
Any amount, any number of people. Divide it equally, by income, or by shares you choose.
Split rent by income
Work out a share that matches what each person earns, instead of an even split that is not even.
Who owes who
Put in what everyone paid and get the fewest payments that settle the whole group up.
Split the bill, with tip
Bill, tip and tax across however many of you, with the spare cent handled honestly.
Split a whole trip
Several expenses, different people paying, not everyone in on everything. One settle-up list.
Split rent by room size
The big bedroom pays more. Any unit works, because only the ratio between rooms matters.
