| Annual Percentage Rate (APR) | The comprehensive total annual cost of borrowing money. | Interest rate + origination fees + prepaid finance charges - autopay discounts. |
Why APR is Almost Always Higher Than the Interest Rate
When an online lender issues you a personal loan, they frequently deduct an origination fee (typically 1% to 8% of the loan value) to cover underwriting and account setup costs.
For example, if you take out a $10,000 personal loan with a 10.00% interest rate and a 5% ($500) origination fee, only $9,500 is disbursed to your bank account, but your monthly payments are based on repaying $10,000 at 10%. This increases your effective borrowing cost to approximately 13.6% APR.
Truth in Lending Act (TILA) Protection
Under federal law (the Truth in Lending Act, enforced by the CFPB and FTC), every lender is legally required to disclose the APR clearly before you sign a loan agreement. This uniform standard allows borrowers to shop and compare competing offers on an equal footing.
Rule of Thumb When Comparing Loans
When evaluating multiple offers for the same loan amount and term, the loan with the lowest APR will almost always be the cheapest loan, regardless of how the lender breaks down base interest and origination fees.
