Split method

What is a utility bill split calculator?

A utility bill split calculator helps divide a shared utility bill between tenants, roommates, or rental units. Enter the total bill amount, choose a split method, and calculate how much each person or unit owes.

Equal utility bill split

An equal split divides the total bill by the number of tenants or units. This is useful when everyone has agreed to pay the same amount.

Example:

A $200 bill split between 4 tenants would be:

$200 ÷ 4 = $50 each

Percentage-based utility bill split

A percentage split divides the bill based on custom percentages. This is useful when tenants or units are responsible for different shares of the bill.

Example:

A $200 bill split as 25%, 35%, and 40% would be:

25% = $50
35% = $70
40% = $80

When to use a percentage split

A percentage split can be useful when rental units are different sizes, when one unit uses more space, or when the lease agreement assigns different shares to each unit.
