APR vs. Interest Rate

Understand the difference between APR (Annual Percentage Rate) and Interest Rate. Calculate the true cost of loans and mortgages.

The Verdict

Interest rate only tells you the cost of borrowing the principal. APR is the more important metric because it represents the true total cost of the loan, including fees and closing costs.
