Simple Interest

by | Feb 10, 2026

In real estate finance, simple interest is interest that is calculated solely on the principal amount of a loan. It does not take into account previously accrued interest.

Simple interest is commonly used in many loan calculations and is distinguished from compound interest, which is calculated on both the principal and accumulated interest. This method results in a straightforward and predictable interest charge over the life of the loan.
