What is APR (Annual Percentage Rate)?
The Annual Percentage Rate (APR) is the true cost of borrowing money, expressed as a yearly percentage. Unlike the nominal interest rate, APR includes all fees, charges, and costs associated with the loan, giving you a complete picture of what you'll actually pay. Required by the Truth in Lending Act (TILA), APR allows you to compare different loan offers on an equal basis.

How APR Calculation Works
The **Annual Percentage Rate (APR)** is the true cost of borrowing money, expressed as a yearly percentage. Unlike the nominal interest rate, APR includes all fees, charges, and costs associated with the loan.
**APR Calculation Methodology:**
We use the **iterative bisection method** to solve for the APR that makes the net present value (NPV) of all loan payments equal to the amount you actually receive.
**The Formula:**
The APR is found by solving for 'r' in the equation:
**Net Loan Amount = Σ (Monthly Payment / (1 + r)^(k/12))** for k = 1 to N
Where:
* **Net Loan Amount** = Amount you actually receive (after fees)
* **Monthly Payment** = Your fixed monthly payment
* **r** = APR (as a decimal)
* **N** = Total number of payments
**What APR Includes:**
* Nominal interest rate
* Origination fees
* Application fees
* Processing fees
* Insurance costs (if financed)
* Other upfront costs

Frequently Asked Questions About APR
Q:What is the difference between APR and interest rate?
The interest rate is the cost of borrowing the principal loan amount, while APR includes the interest rate plus all fees and charges. APR gives you the true cost of the loan. For example, a loan with a 5% interest rate but $500 in fees might have an APR of 6.2%.
Q:Why is APR higher than the interest rate?
APR is higher because it includes all costs: origination fees, application fees, processing fees, and insurance (if financed). These additional costs are spread over the loan term and expressed as an annual percentage, making the APR higher than the base interest rate.
Q:Should I choose a loan with a lower APR?
Generally, yes. A lower APR means a lower total cost of borrowing. However, consider the loan term as well. A shorter-term loan might have a higher APR but lower total interest paid. Use our calculator to compare the total cost of different loan options.
Q:Does APR include late payment fees?
No, APR only includes fees that are part of the loan origination process. Late payment fees, prepayment penalties, and other conditional fees are not included in the APR calculation.
Q:How is APR calculated for loans with different payment frequencies?
APR is always expressed as an annual rate. For loans with monthly payments, we convert the monthly rate to an annual rate. The calculation accounts for the compounding frequency to ensure accurate comparison across different loan structures.
Q:Can I use APR to compare loans with different terms?
Yes, APR is designed to allow comparison of loans with different terms and fee structures. However, also consider the total amount you will pay over the life of the loan, as a longer-term loan might have a lower APR but higher total interest.
