Assumptions and limitations

  • Assumes the same rent for all 12 months. These are alternative fee bases to compare, not amounts to add together.

Common questions

Is 10% here applied to monthly rent?

No. The custom percentage applies to annual rent. At monthly rent of 2,000, 10% of annual rent is 2,400. To solve for the percentage from a fee amount, enter annual rent directly, clear the prefilled percentage, then enter the fee amount.

What annual percentage equals one month of rent?

One month is one twelfth of annual rent, or 8.333…%. Half a month is 4.1666…%, and one and a half months is exactly 12.5%.
