About this calculator

Each person's share of the total bills is their contribution value divided by everyone's contribution added together — which is why percentages don't need to add up to exactly 100%, they're normalized automatically.

In income mode, the same maths applies to income figures instead, so someone earning twice as much as their housemate pays twice as much toward shared bills.
