Understanding the Annual Percentage Rate (APR) is crucial when comparing savings accounts. Our APR calculator for savings account helps you determine the true cost of interest on your savings, allowing you to make informed financial decisions.
What is APR?
The Annual Percentage Rate (APR) represents the annual interest rate charged on a savings account. It's a key figure when comparing different savings products because it shows the actual cost of borrowing or the return on your savings.
Key Point
APR is calculated on the principal balance of your account, not including any interest that has accumulated. This means the APR remains constant regardless of how much interest you earn.
APR is typically expressed as a percentage and is used to calculate the interest earned or paid over a year. For savings accounts, a higher APR means you'll earn more interest on your deposits.
How to Calculate APR
Calculating APR involves determining the interest rate based on the principal amount and the interest earned. The basic formula for APR is:
APR Formula
APR = (Interest Earned / Principal Balance) × 100
For example, if you deposit $1,000 into a savings account and earn $25 in interest over the year, your APR would be 2.5%.
Step-by-Step Calculation
- Determine the principal amount (the initial deposit).
- Calculate the total interest earned over the year.
- Divide the interest earned by the principal amount.
- Multiply the result by 100 to get the percentage.
Important Note
APR calculations are straightforward for simple interest accounts. For accounts with compound interest, the APR is calculated based on the simple interest equivalent over the same period.
APR vs. APY
While APR and Annual Percentage Yield (APY) are often used interchangeably, they represent different concepts. APR is the simple interest rate, while APY accounts for compounding interest.
APY Formula
APY = (1 + (APR / n))^n - 1
Where n is the number of compounding periods per year.
For example, if a savings account offers a 2% APR with monthly compounding, the APY would be approximately 2.02%. The difference between APR and APY becomes more significant with higher interest rates or more frequent compounding periods.

Frequently Asked Questions
What is the difference between APR and APY?
APR is the simple interest rate, while APY accounts for compounding interest. APY is always higher than APR for accounts with compound interest.
How often is APR calculated?
APR is typically calculated annually, based on the interest earned over the year. It's a simple interest rate that doesn't account for compounding.
Can APR be negative?
Yes, APR can be negative if you're charged fees or interest on a loan. For savings accounts, APR is typically positive.
Is APR the same as the interest rate?
For simple interest accounts, yes. For accounts with compound interest, the interest rate is different from APR, which is based on the simple interest equivalent.
