1. To determine the true APR, gather all loan details, including principal amount, the loan term, payment frequency, interest rate, and fees
2. Take the monthly (or weekly) payment quoted by the loan provider and multiply it by the total number of payments you need to make to pay off the loan. For example, if you take a $10,000 loan that is repayable over a six-month term with equal payments of $2,100 per month, your calculation would be 6 (payments) x $2,100 (amount per payment) = $12,600.
3. Add all additional fees. For example, most lenders charge an origination fee. $500 (origination fee) + $12,600 (total sum of your monthly payments) = $13,100.
4. Subtract the loan principal from the sum of total payments + fees. $13,100 (total payments + fees) - $10,000 (loan principal) = $3,100 (the total amount, over-and-above the loan principal, you will end up paying).
5. Divide that number by the loan principal. $3,100 / $10,000 = .31.
6. Divide by the number of days in the loan term. .31 / 180 = .0017222 (the number of days in the loan term equals 180 because there are roughly 180 days in a 6-month period)
7. Multiply by 365 days. .0017222 x 365 = .6286
8. Multiply by 100 to arrive at a percentage. .6286 x 100 = 62.86% APR
9. So, under this scenario, your annual percentage rate (APR) is 62.86%.
For the scenario described above, some lenders will quote you a 31% interest rate because that's the rate you will pay over the six-month loan term. Other lenders will quote you a monthly interest rate of 5.16%. In both cases, the true APR is 62.86%. Other lenders won't include the additional "fees" they charge in their rate calculation. The amount a lender charges you in fees can make a big difference to your annual percentage rate. By not including all fees within an APR they quote you (or don't quote you) is a deceptive loan practice. You're smarter than that. Don't be duped.
