A worked example, without JavaScript

For $900 in shared bills, an equal split is $450 each. With incomes of $3,600 and $2,400 for the same period, an income-based split is 60 / 40: $540 and $360. Contributions of $620 and $280 are $80 above and $80 below those respective shares.

An illustration—not your bank balance or a transfer instruction. One person’s extra doesn’t automatically settle the other’s share.

A little context

The numbers, in plain language.

Choose together

Equal means half each. Custom uses percentages you agree on. Income-based uses each person’s proportion of your combined take-home pay—not a rule about what you should pay.

Compare the approaches

Share isn’t contribution

Your share is the part of the bills allocated to you. Your contribution is what you’ve put in. If your share is $360 and you’ve contributed $280, you’re $80 below that share.

A snapshot, not a ledger

This tool leaves out earlier balances, individual bills, timing, carried credit and credit-use choices. The app uses your household’s recorded activity. This calculator is separate and isn’t financial advice.
