Income Split Calculator: Fair Bills Based on What You Earn
Equal splits feel fair on the surface, but they hit lower earners disproportionately hard. When one person earns three times as much as another, paying the same flat amount is actually regressive. Proportional splitting fixes that by matching each person's share to their financial capacity.
