Compound Interest
Definition and meaning of Compound Interest in real estate.
Compound interest is interest calculated on both the initial principal amount of a loan or investment and the accumulated interest from previous periods.
In more detail
While traditional fixed-rate home mortgages typically use simple interest calculated monthly on the remaining principal, compound interest plays a major role in other financial areas, such as savings accounts, credit cards, and certain types of loans. For investors, compound interest helps build wealth over time as earnings generate their own earnings.
However, for borrowers, compounding can make debt much harder to pay off if payments do not cover the interest charged. For example, negative amortization loans, which are rare and risky, compound interest when unpaid interest is tacked onto the loan balance. Understanding how compounding periods, such as daily, monthly, or annually, affect the annual percentage yield is key to managing real estate investments.

Frequently asked questions
Do standard home mortgages use compound interest?
No, most standard U.S. mortgages use simple interest, meaning interest is calculated only on the remaining principal balance, not on accrued interest.
What is negative amortization in relation to compound interest?
Negative amortization occurs when the monthly payment is less than the interest owed, causing the unpaid interest to be added to the principal, where it compounds.
