Finance & Money
APR Calculator
Enter stated principal, equal scheduled payment, payment count, payment frequency, and prepaid finance charges. The calculator deducts charges from proceeds, solves the periodic discount rate, and converts it to a nominal annual cash-flow APR estimate.

How to use APR Calculator
- Enter the stated principal, equal payment amount, total number of payments, payments per year, and prepaid charges deducted before funding.
- Review net proceeds, scheduled total, finance cost, and the solved periodic and nominal annual rates.
- Compare the result only as an initial screen and use the lender's dated cash flows and official APR disclosure for a contractual decision.
Calculator guide
Understanding APR Calculator
APR is a cash-flow rate, not aggregate finance cost divided by principal and years. This page solves the periodic rate that makes net credit received equal to the present value of the complete equal-payment stream.
Worked situations
Practical examples
- For $20,000 financed with $23,500 of scheduled payments and $500 of included fees, enter the amounts exactly once so fees are not duplicated.
- Use the same definition of total payments when comparing two offers; do not include a down payment in one and exclude it from the other.
- If a fee is paid separately but required to obtain credit, include it only when the intended APR convention treats it as a finance charge.
Better inputs
Useful tips
- Request the lender's official APR and payment schedule before making a final comparison.
- Compare term, monthly cash requirement, total finance cost, prepayment rules, and collateral terms alongside APR.
- Separate optional products from mandatory credit charges and document which fees were included.
Before relying on the result
Limitations and common mistakes
- The solver assumes equal intervals and equal payments; it is not a dated-cash-flow disclosure engine for odd first periods or irregular installments.
- Jurisdiction-specific fee inclusion, odd first periods, compounding, payment frequency, rebates, and balloon payments are not represented.
- The displayed APR must not be treated as an official disclosure or a determination of legal compliance.
Reference
Key terms
- Amount financed
- Principal amount treated as credit provided to the borrower in this simplified comparison.
- Finance cost
- Total scheduled payments plus entered financing fees minus amount financed.
- Cash-flow APR estimate
- Solved periodic rate multiplied by the entered number of payment periods per year.
- Contractual APR
- APR calculated under applicable disclosure rules from the actual timing and classification of cash flows.
Important note
APR means annual percentage rate: the standardized yearly borrowing-cost measure used to compare credit offers with their stated interest and included finance charges.
Frequently asked questions
Why can this differ from a lender's APR?
Official APR can use exact dates, prescribed fee classifications, special rounding, insurance treatment, and irregular first or final periods.
Are all fees included in APR?
No. Applicable rules distinguish finance charges from excluded or optional costs; verify the treatment for the product and jurisdiction.
Is a lower APR always the cheaper offer?
Not automatically. Different terms, loan amounts, optional products, prepayment plans, and required cash at closing can change total cost.
Can this calculate APR from a monthly payment?
Yes for an equal-period, equal-payment stream. Dated or irregular cash flows require a date-aware yield calculation.
