Rent split by income calculator
Divide rent so it tracks what each roommate earns instead of splitting it down the middle. Slide between a pure equal split and a fully income-weighted one to land on a number the whole apartment agrees is fair.
0% is a plain equal split · 100% is fully income-proportional.
Assigned rent: $2,400.00 · Exact to the cent · Equal split would be $800.00 each
Agreed on the split?
Send each roommate their exact share as a private monthly request and track who has paid. $29/month for the host.

Common questions
Is it legal to split rent by income?
Yes. How co-tenants divide the rent between themselves is a private agreement. The lease still makes every named tenant jointly responsible to the landlord for the full amount, so an income split only changes who reimburses whom, not what the landlord can collect.
Should I use gross or net income?
Gross monthly income (before tax) is the simplest shared basis because everyone can state it without revealing deductions. Net take-home is arguably fairer but harder to compare across different tax situations. Pick one basis and use it for everyone.
What does the fairness slider do?
It blends two splits. At 100% each person pays in direct proportion to income. At 0% everyone pays the same. A middle setting such as 60% tilts the bill toward higher earners while keeping a floor so no one pays far below their means.
Why can the shares differ by a cent?
A proportional split rarely lands on whole cents. The calculator distributes the leftover cents deterministically so the displayed shares always add back to the exact rent instead of losing or inventing money.
Does this calculator collect the rent?
No. It only works out the shares. TabChaser can turn those exact amounts into private payment requests and track who has paid, but this page never touches money.
