On a $10,000 personal loan at 18% with an 8% origination fee over 3 years, the real APR is 24.12%. The fee adds 6.12% to the rate, so you pay $3,815 to borrow $9,200.
The math
Inputs
| Loan amount | $10,000 |
|---|---|
| Interest rate | 18% |
| Term | 36 months (3 years) |
| Origination fee | 8% |
The formula in words
The monthly payment is set on the full $10,000, but the fee comes out first, so you only get $9,200. The real APR is the yearly rate at which your 36 payments are worth exactly the cash you received: solve present value of payments = cash received for the monthly rate, then × 12.
Step by step
| Step | Calculation | Result |
|---|---|---|
| Fee | $10,000 × 8% | $800 |
| Cash received | $10,000 − $800 | $9,200 |
| Monthly payment | $10,000 at 18% for 36 months | $361.52 |
| Total of payments | $361.52 × 36 | $13,015 |
| Real APR | rate at which 36 payments of $361.52 are worth $9,200 today | 24.12% |
Result
- Origination fee: $800
- Cash you actually receive: $9,200
- Monthly payment: $361.52
- Total of payments: $13,015
- Total interest: $3,015
- Total cost of borrowing (interest + fee): $3,815
- Real APR including the fee: 24.12%
- APR added by the fee: 6.12%
Assumptions
- The fee is deducted from the loan proceeds, as most personal-loan lenders do.
- APR found by the actuarial method used for Truth in Lending disclosures; a lender's disclosed APR may differ slightly because of payment dates.
- These are estimates that show how the math works, not financial, tax or legal advice. Lenders, card issuers and the IRS can calculate slightly differently.

What the 24.12% Real APR Means for You
The advertised 18% interest rate is not what you actually pay when an 8% origination fee is deducted upfront. Because the fee comes out of the loan before you receive the money, you only get $9,200 in cash, yet your monthly payment of $361.52 is still based on the full $10,000. Over 36 months, that payment totals $13,015. The real APR of 24.12% captures both the interest and the fee, giving you a single number to compare offers. It means the true yearly cost of borrowing is 24.12%, not 18%. If you were comparing this loan to another with no fee, the other loan would need an interest rate of 24.12% to be equally expensive.
What Drives the Real APR Higher
Two things push the real APR above the advertised rate: the size of the origination fee and the loan term. The fee is 8% of $10,000, or $800. That $800 is money you never get to use, but you still pay it back with interest because your payments are based on the full $10,000. The longer the term, the more months you pay interest on that $800, which is why the fee adds 6.12% to the APR over 3 years. If the fee were lower, the added APR would be smaller. If the term were shorter, the fee would be spread over fewer payments, but each payment would be higher. The real APR is the best single measure because it accounts for both the fee and the time you have the money.
How You Could Change the Outcome
Using only the numbers here, you can see that the real APR depends on the fee and the term. If you could find a lender that charges no origination fee, your real APR would be the 18% interest rate, assuming the same term and payment. If you could negotiate the fee down, the real APR would drop, though the exact new rate would depend on the new fee. If you chose a shorter term, your monthly payment would be higher, but you would pay the fee over fewer months, which could lower the real APR. However, any change to the fee or term would require a new calculation. The key takeaway is that the origination fee is not a one-time cost you can ignore; it raises your effective rate for the entire loan.
Practical Next Steps
Before you sign, ask the lender for the disclosed APR, which by law must reflect the origination fee. Compare that number to the 24.12% real APR you calculated here. If the lender's APR is different, ask why. Also ask whether the fee is deducted from the proceeds or added to the loan balance; this calculation assumes it is deducted, which is common. If you are comparing multiple offers, use the real APR as your yardstick, not the interest rate. Finally, remember that these are estimates. Your actual payment dates and the lender's method can change the APR slightly. Confirm all numbers with your lender before you commit.
Frequently asked questions
Why is the real APR higher than the interest rate?
The real APR includes the 8% origination fee, which is $800. Since the fee is taken out before you get the money, you receive only $9,200 but still make payments on $10,000. That extra cost raises the effective annual rate to 24.12%.
How much does the origination fee add to the APR?
The fee adds 6.12% to the APR. Without the fee, the APR would be the 18% interest rate. With the fee, the real APR is 24.12%. This difference shows the true cost of the fee over the 36-month term.
What is the total cost of this loan?
You pay $13,015 in total payments. Of that, $3,015 is interest and $800 is the origination fee, for a total cost of borrowing of $3,815. You receive $9,200 in cash, so the loan costs you $3,815 to borrow that amount.
Can I avoid the origination fee?
Some lenders may offer loans without an origination fee, but they might charge a higher interest rate instead. You would need to compare the real APR of each offer. This calculation assumes an 8% fee, so if you find a no-fee loan, your real APR could be lower.
Does the real APR change if I pay the loan off early?
This calculation assumes you make all 36 payments on schedule. Paying early could reduce the total interest you pay, but it might not change the disclosed APR, which is based on the scheduled payments. Check with your lender for any prepayment rules.
