Guide to Understanding Loan Interest Rates and Fees

The interest rate is the yearly cost of borrowing the principal; the APR adds certain fees to show a more complete yearly cost. When comparing loans of the same amount and term, the one with the lower APR generally costs less overall.

Interest rate vs. APR

  • Interest rate: the percentage charged on your outstanding balance each year.
  • APR (annual percentage rate): includes the interest rate plus certain required fees, such as origination fees, expressed as a yearly rate.

Under the federal Truth in Lending Act, lenders must disclose the APR, which makes comparisons easier.

How amortization works

With an installment loan, each payment covers that month's interest first; the rest reduces the principal. Early on, more of your payment goes to interest. As the balance falls, more goes to principal.

Example: A $10,000 loan at 10% APR over 36 months has a payment of about $323. Total paid: about $11,616, so roughly $1,616 is interest. The same loan over 60 months has a lower payment of about $212, but total interest rises to about $2,748.

Common loan fees

FeeWhat it is
Origination feeCharged for processing the loan; often deducted from the amount you receive
Late feeCharged when a payment is late
Returned payment feeCharged if a payment bounces
Prepayment penaltyCharged for paying off early — avoid loans that have one if possible
Application feeUncommon for personal loans; be cautious if required upfront

How origination fees affect you

If you borrow $10,000 with a 5% origination fee deducted upfront, you receive $9,500 but repay the full $10,000 plus interest. If you need exactly $10,000, you'd have to borrow more.

What determines the rate you're offered
