Split bills.
Stay fair.
CoBills splits shared bills three ways — by income ratio, 50/50, or custom percentage. Pick the mode that fits each bill, and skip the awkward money math.
Same rent, three ways to split fair.
Alex earns $4,800/mo. Sam earns $3,200/mo. Rent is $2,400. Pick the split mode that feels fair for the bill.
Proportional to take-home pay — the mode that matters when incomes don't match, so nobody has to argue what's fair.
