SplitFair: Household Cost Divider by Usage & Income

How it helps

Use it for a focused task

SplitFair helps households divide costs in a way that feels fair and prevents resentment. Most calculators force 50/50 splits or only count square footage.

This one adds income proportionality, usage patterns, and real-life complications like guests, pets, and surprise repairs. The page includes a scenario walkthrough showing how three roommates with different incomes and room sizes reach an agreement, plus a comparison of equal vs.

income-proportional methods. Start by adding each household member and their details: income, private space size, and estimated shared space usage.
