Fair split calculator

What's a fair split?

Two pays, one set of bills. Here are three common ways couples cover what they share, with what each of you pays and what each of you keeps. None of them is the right one; the right one is the one you both think is fair.

Take-home is what lands in the bank after tax. Nothing you type here leaves this page.

50/50

Each of you pays half the shared bills from your own pay.

Youpays $1,500
keeps $3,700 for everything else
Your partnerpays $1,500
keeps $1,900 for everything else

The bills are the same dollars for each of you, but they take 29% of one pay and 44% of the other.

By income

Each of you pays the share of the bills that your pay is of the two pays together.

Youpays $1,814
keeps $3,386 for everything else
Your partnerpays $1,186
keeps $2,214 for everything else

60% and 40% of the bills. The bills take the same 35% of each pay, so the one who earns more still keeps more.

Pool it all

Both pays go in one pot, the bills come out, and what's left is split evenly.

Youpays $2,400
keeps $2,800 for everything else
Your partnerpays $600
keeps $2,800 for everything else

You each end up with the same $2,800. The one who earns more puts in more to get there.

Wonderful does this every month, with your real bills.

You each connect your own bank and choose what the other sees. It divides what you share half each or by income, or treats it all as one pot, and keeps track of who owes whom.
