Understanding the APR Calculator

The APR (Annual Percentage Rate) Calculator is a tool that helps you determine the true cost of borrowing money. It includes not just the interest rate, but also any fees associated with the loan, giving you a clearer picture of the overall cost of the loan.

What is APR?

APR represents the annual cost of a loan, expressed as a percentage. It includes the interest rate and additional fees, such as origination and application fees. Unlike the interest rate, APR provides a comprehensive view of the loan's cost, helping you make more informed financial decisions.

Formula Used

The APR calculation is performed using the following formula:

\( APR = \dfrac{TotalFees + LoanAmount}{LoanTerm \times 12} \times 100 \)

The calculation uses the Newton-Raphson iterative method to adjust for loan costs over time. For monthly payments, the formula is:

\( M = P \cdot \dfrac{r(1+r)^n}{(1+r)^n - 1} \)

  • \( M \) = Monthly Payment
  • \( P \) = Loan Amount
  • \( r \) = Monthly Interest Rate (Annual Rate ÷ 12)
  • \( n \) = Total Number of Payments

Difference Between APR and APY

While APR focuses on the annual cost of a loan (including fees), APY (Annual Percentage Yield) reflects the annual rate of return, including the effects of compounding interest. APR is borrower-focused, while APY is more applicable to savings or investments.

How It Works

The calculator takes into account the following inputs:

  • Loan Amount: The principal amount borrowed.
  • Interest Rate: The annual percentage charged for borrowing.
  • Loan Term: The duration of the loan in years.
  • Loan Fees: Includes origination, application, and other fees.

By entering these details, the calculator provides:

  • The accurate APR for the loan.
  • The monthly payment amount.
  • Total interest paid over the loan term.
  • The overall cost of the loan (principal + interest + fees).
