Income split calculator

Your income. Their income.
Two cherries together.

Type what you each earn and see the share of every bill that matches it. When being wise doesn't work, have another cherry.

Use the same period for everyone, yearly or monthly, before tax or after. Only the ratio matters, and nothing you type leaves this page.

Why a ratio, not a half

Half and half is easy. Fair takes a ratio. In 29% of marriages today both spouses earn about the same amount of money, which means that in most, they don't.[1] An even split asks the person earning less to feel the same bill more.

The margin isn't wide for a lot of households. In the Federal Reserve's 2024 survey, 73% of adults said they were doing okay or living comfortably financially, and 63% said they could cover a hypothetical $400 emergency expense with cash or its equivalent.[2] A split that tracks income is how the person with less room keeps some.

It starts with a conversation most couples skip. In Fidelity's Couples and Money research, nearly 4 in 10 partners couldn't correctly identify what the other earns.[3] Two numbers in the boxes above is that conversation, done.

Prefer to read first? Why equal isn't always fair, and how to split by income without it feeling like a ledger.
