Roommate Expense Split Calculator

About this calculator

Splitting a household with roommates usually means dividing shared costs — rent, utilities, internet, groceries bought together — into equal shares so nobody overpays or underpays for the space and services everyone uses in common. The math itself is simple, but keeping every bill, every month, split fairly and transparently is where disputes usually start.

This calculator adds up your shared household expenses and divides the total evenly by the number of roommates, giving each person's fair share in one step. It's a practical tool for roommates settling a monthly bill run, for people moving into a shared apartment who want to agree on the split upfront, or for anyone who just wants a neutral number to point to instead of doing the math by hand.
