Frequently Asked Questions

How does proportional expense splitting work?

Proportional splitting divides expenses based on each person's income. The higher earner contributes more in absolute terms, but both contribute the same percentage of their income.

When should I use 50/50 vs proportional split?

50/50 works well when incomes are similar (difference less than 20-30%). Proportional split is fairer when there's a significant income gap.

Does this calculator work for couples with different currencies?

This calculator assumes the same currency for both incomes. If you earn in different currencies, convert to the currency you use for expenses first.
