About the Rent Split Calculator
Calculate equal totals or distribute one total in proportion to custom weights.
Formula
Equal shares divide by roommate count. Weighted shares multiply total cost by each weight divided by the sum of weights.
Example
Weights 1, 1.2 and 0.8 divide the total in proportions of 33.33%, 40% and 26.67%.
Notes
Weights are calculation inputs only and do not determine any contractual responsibility.
