Annual Percentage Rate (APR) represents the total cost of borrowing over a year, expressed as a percentage. It includes interest rates and additional fees, giving borrowers a clearer understanding of the actual cost of a loan or credit. APR is widely used for loans, credit cards, and mortgages to compare different financing options.

How APR Works

APR accounts for both the nominal interest rate and any additional costs, such as:

• Loan origination fees
• Closing costs (for mortgages)
• Credit card annual fees

APR helps consumers compare different loan offers by standardizing the cost of borrowing.

Types of APR

1. Fixed APR – Remains constant over the loan term.
2. Variable APR – Changes based on a benchmark interest rate (e.g., LIBOR or Prime Rate).
3. Introductory APR – A promotional low or 0% rate for a limited period on credit cards.
4. Penalty APR – A higher rate applied when borrowers miss payments.

APR Formula

The basic APR formula is: APR=(Total Interest + FeesLoan Amount)×365Loan Term in Days×100APR = \left( \frac{\text{Total Interest + Fees}}{\text{Loan Amount}} \right) \times \frac{365}{\text{Loan Term in Days}} \times 100

APR vs. Interest Rate

Why APR Matters

• Transparency – Shows the true cost of borrowing.
• Better Loan Comparisons – Helps consumers choose the most cost-effective option.
• Regulatory Requirement – Lenders must disclose APR to borrowers.

Limitations of APR

• Does Not Include Compounding – Unlike the Annual Percentage Yield (APY), APR does not factor in interest compounding.
• May Underestimate Costs – If fees vary or additional charges apply.
