Formula Used

1) Periodic interest rate
i = (1 + r / c)c / p − 1

r = nominal annual rate, c = compounding periods per year, p = payment frequency per year.

2) Base payment
Payment = P × i ÷ (1 − (1 + i)−n)

P = principal and n = total payment periods.

3) Amount financed
Amount Financed = Principal − Upfront Fees + Lender Credits

4) APR estimation
Amount Financed = Σ [Total Periodic Payment ÷ (1 + a)t]

The calculator solves for periodic APR rate a with bisection, then annualizes it as APR = a × payment frequency.

5) Effective annual rate
EAR = (1 + a)p − 1

This model assumes equal scheduled payments and fees over the term entered.

FAQs

1) What does APR mean in this calculator?

APR estimates the yearly borrowing cost after combining interest, upfront fees, and recurring charges. It gives a truer comparison than rate alone.

2) Why is APR sometimes higher than the quoted rate?

APR rises when lenders charge origination fees, points, monthly service fees, or insurance. Those costs reduce your net proceeds while payments stay the same.

3) Does the lowest monthly payment always mean the best loan?

No. Longer terms often lower payments but increase total interest and overall finance charge. Compare payment with APR and total cost together.

4) Can I compare loans with different terms?

Yes. The calculator is designed for different terms, fee structures, and payment frequencies. Cost per $1,000 financed helps normalize the comparison.

5) What fees should I include?

Include fees tied directly to getting or maintaining the loan, such as origination, filing, service, insurance, or discount points if applicable.

6) How do lender credits affect APR?

Lender credits increase the amount financed received by the borrower. That can reduce APR when the credit offsets other upfront borrowing costs.

7) Is this the same as an official disclosure statement?

No. This tool is an analytical estimate for comparison. Final lender disclosures may use regulated assumptions, rounding, and product-specific rules.

8) How accurate is the APR estimate here?

It is strong for fixed-payment loans with stable fees. Accuracy falls when products have balloon payments, irregular schedules, teaser rates, or changing insurance.
