Borrowing comparison
A lower interest rate is not always the cheapest offer if the lender charges higher fees. APR helps compare loan offers using both rate and costs, while the total-cost view helps when you plan to keep the loan for only a few years.
Use cases
Use it before comparing loan offers, reviewing credit card debt, checking lender fees, or deciding whether a lower rate is worth higher upfront costs.
