What is APR?


Last Updated: 8 January 2025
Reviewed By: Ian Wright (Managing Director)

APR, or Annual Percentage Rate, is a comprehensive measure of the cost of borrowing on an annual basis, expressed as a percentage. It includes not only the interest rate but also any additional fees or charges associated with the loan or credit product. APR is designed to provide borrowers with a clear, standardized measure to compare the cost of different credit and loan offers.

Key Aspects of APR:

  • Inclusive of Fees: Unlike a simple interest rate that only reflects the cost of interest, the APR includes interest plus other charges, such as origination fees, closing fees, and insurance, if they’re required as part of the loan. This means the APR can provide a more accurate reflection of the total cost of borrowing.
  • Standardization: The APR is a standardized measure, which means it’s calculated in the same way by all lenders. This standardization helps borrowers compare different loan and credit offers on an equal basis.
  • Annual Basis: The APR is annualized, which allows borrowers to understand the cost of borrowing over a period of one year. This is particularly useful for comparing loans of different lengths.

Types of APR:

  1. Fixed APR: The interest rate remains constant throughout the term of the loan, which means the borrower’s payments are predictable and unaffected by changes in the market interest rates.
  2. Variable APR: The interest rate can change over time based on an index or benchmark rate, such as the Prime Rate. This means the borrower’s payments can vary, going up or down with changes in market conditions.

APR in Different Credit Products:

  • Credit Cards: APRs can vary for purchases, balance transfers, and cash advances. Credit cards might also offer a promotional APR, which is a lower rate for a limited period.
  • Mortgages: The APR for mortgages includes the interest rate plus other costs, such as broker fees, closing costs, and any other charges necessary to obtain the mortgage.
  • Personal Loans and Auto Loans: Similar to mortgages, the APR includes the interest rate and any fees charged by the lender.

Importance:

Understanding the APR is crucial for borrowers because it affects the total amount they will pay over the life of the loan. A lower APR means lower costs to the borrower, making it an essential factor in choosing between different credit offers.

However, it’s also important to consider other aspects of a loan, such as the term, monthly payments, and the total amount repayable, to get a complete picture of the loan’s affordability.

How is APR different from AER?

The difference between APR and AER (Annual Equivalent Rate) primarily lies in their use and what they represent in the financial world. While both rates are expressed annually, they serve different purposes and are used in different contexts:

APR (Annual Percentage Rate)

  • Purpose: APR is primarily used in the context of borrowing. It represents the annual cost of borrowing money, including interest and any additional fees or charges associated with the loan or credit product.
  • Comprehensiveness: APR includes not just the interest rate but also any other charges that are mandatory as part of obtaining the credit (e.g., origination fees, closing fees). This makes it a more comprehensive measure of the cost of borrowing.
  • Focus on Borrowing Costs: The primary purpose of APR is to give borrowers a clear, standardized way to compare the cost of loans and credit offerings from different lenders. It reflects the total cost of the loan on an annual basis as a percentage of the loan amount.

AER (Annual Equivalent Rate)

  • Purpose: AER is used in the context of saving and investing. It indicates the interest rate for savings accounts or interest-bearing investment products, calculated over a year and taking into account the effect of compounding.
  • Compounding Interest: AER shows the potential interest rate one might earn on their savings or investments, assuming the interest is compounded over the year. It is designed to reflect the true rate of return, considering the frequency of interest payments (e.g., monthly, quarterly).
  • Focus on Earnings: AER is aimed at savers and investors to help them compare the annual interest yield on different savings products on a like-for-like basis. It highlights how much interest their money could earn in a year.

Key Differences

  • Context and Application: The most significant difference is their context of use; APR is used for borrowing, whereas AER is used for saving or investing.
  • What They Include: APR takes into account both interest and fees to show the total cost of a loan, while AER focuses solely on the interest earnings, including the effect of compounding, but does not include fees because it’s related to earnings on savings, not costs.
  • Objective: The APR is designed to provide transparency about the total cost of a loan, helping consumers compare loans more easily. In contrast, the AER helps savers understand the effective annual interest rate they will receive on their savings, taking compounding into account.

Understanding these differences is crucial for making informed financial decisions, whether you’re looking to borrow money and need to understand the full cost of a loan (APR) or you’re comparing savings accounts to find the best return on your deposits (AER).
