How this calculator works
Percentage splitting applies the custom share entered for one roommate and assigns the rest to the other. The table shows the monthly share for each person so the agreement can be checked before anyone pays.
When to use this page
Use it when two people have already agreed on Person A’s percentage and Person B will pay the remainder.
Choosing a fair split method
A percentage split is useful when roommates already agreed on exact shares because of room size, private space, parking, pets, or another practical tradeoff.
Utilities and shared costs
Rent and utilities do not always need the same split. Some households split rent by room value but split internet, electricity, water, or supplies equally. Put only the shared costs you want included into the calculator.
What this result does not include
This does not decide legal responsibility under the lease, damage deposits, late fees, household chores, variable utility usage, or what happens if one roommate cannot pay.
Worked examples
Room value adjustment
A 60/40 split can fit a larger bedroom, private bathroom, parking spot, or other agreed value difference.
Custom share check
Use the percentage result to confirm the exact dollar shares before collecting rent, especially when the split includes utilities or fees.
