How to Read Your Calculator Results
The monthly payment figure is only one of three numbers that matter. Total interest paid shows the true cost of stretching a loan over a longer term: a $15,000 loan at 14.99% APR costs roughly $3,680 in interest over 36 months but about $6,360 over 60 months — the lower monthly payment of the longer term costs an extra $2,680 in total. Effective APR including origination fee matters because the 1%–5% origination fee is deducted from your disbursement up front; on a $15,000 loan with a 5% fee you receive $14,250 but repay interest on the full $15,000, which raises your true annualized cost above the stated rate. Amortization split shows how early payments are interest-heavy — in month one of a 36-month loan at 14.99%, roughly a third of your payment is interest, falling toward zero by the final payment.
Three levers reduce your total cost more than shopping a fraction of a percent on APR. Choosing a 36-month term over 60 months typically saves 40%–45% of total interest. Borrowing only what you need matters because origination fees scale with principal. And improving your FICO band before applying — even moving from the 640–679 tier to 680–719 — can shift your offered APR by several full percentage points, which compounds over every month of the term.
This calculator uses the standard amortization formula required for TILA disclosures, so its output should closely match the payment schedule in any compliant lender's offer document. The CFPB publishes a plain-language guide to interest rate versus APR if you want the regulatory definitions behind these figures.
Frequently Asked Questions
Questions about using this tool and interpreting results.
This calculator provides estimates based on the standard loan amortization formula (PMT). Actual monthly payments may differ slightly based on the lender's rounding method, payment date, and whether the origination fee is added to the loan principal or deducted from disbursement. Always verify final terms in your lender's official offer disclosure.
The origination fee reduces the amount you actually receive (disbursement), while your monthly payments are calculated on the full loan principal. For example, on a $10,000 loan with a 2% fee, you receive $9,800 but repay $10,000 + interest.
Enter each offer's APR, term, and origination fee separately and note the "full true cost" figure. A lower monthly payment with a longer term often has higher total interest — the true cost metric captures this.
Not always for short terms. A 16% APR loan for 24 months may have lower total interest than a 12% APR loan for 60 months, simply because you repay faster. Use the total interest field to compare apples-to-apples.
