Understanding APR

How the annual percentage rate is defined, calculated, and used to compare financing.

What does APR represent?

APR, or annual percentage rate, expresses the yearly cost of borrowing as a single percentage. It gives a standardized figure that can be used to compare the cost of different financing offers on the same basis.

What is nominal APR?

Nominal APR shows the annual cost of financing without compounding. It takes the total cost of borrowing and spreads it evenly across the number of periods in a year, producing a flat annual percentage.

How does nominal APR differ from true APR?

Nominal APR multiplies the periodic cost by the number of periods in a year, while true APR compounds the periodic rate across the year. In everyday practice the difference between the two is usually small.

Why is APR useful for comparison?

Because it places offers with different term lengths and payment frequencies onto the same yearly scale, APR lets a borrower line up a shorter option and a longer option and compare them directly.

Why can APR alone be misleading?

APR assumes financing is held for its entire scheduled term. It does not capture savings from early repayment, differences in flexibility, or the value the capital might create, so two offers with the same APR can behave quite differently.

Does a shorter term always mean a worse APR?

Not in terms of dollars. A faster payoff can raise the APR figure even when the total amount repaid is identical, simply because the same cost is compressed into a shorter window of time.
