Split by income

Enter the shared bills and each person's net income. The calculator gives what everyone pays: the same percentage of their income for each.

Everything is worked out in your browser: nothing is sent, nothing is kept.

How it is worked out

1

The household's net incomes are added up, then the shared bills are divided by that total: this gives the percentage everyone pays. Each person pays that percentage of their own income. Whoever earns more pays more, and everyone keeps the same proportion of what they earn.

2

With 1,400 € of shared bills, one income of 1,800 € and one of 3,200 €, the rate is 28 %: 504 € for the first, 896 € for the second. The calculation rounds to the cent and gives the cent left over to someone: the total paid always makes exactly the bills.

The formula
Rate= Shared bills ÷ sum of the incomes
Each share= The person's income × Rate

Questions

Is splitting by income fairer than 50/50?

When incomes are close, both come to almost the same. As the gap grows, 50/50 takes a larger part of the lower income. Splitting by income leaves everyone the same proportion of what they earn.

Income before or after tax?

Usually after: the net income, what arrives on the account. What matters is counting everyone the same way.

And when a salary changes?

The calculation is redone with the new income. In fleen, every bill keeps its split in percentages: you update it, and it applies from the next month.

Is a joint account needed?

No. Everyone can keep their own account and pay their share, or front some bills: fleen works out who owes what, and one transfer at the end of the month evens everyone out.
