How Interest on Savings Works

Interest on savings accounts typically works on a compounding basis, meaning you earn interest not only on your initial deposit but also on the accumulated interest from previous periods. The more frequently interest is compounded, the more you'll earn over time.

There are two main types of interest rates:

APR (Annual Percentage Rate): The annual rate of interest charged or paid, without compounding.
APY (Annual Percentage Yield): The actual annual rate of interest earned, taking into account compounding.

Our calculator uses APR to calculate the interest paid, but it shows both APR and APY for comparison.

Formula Used

The calculation is based on the compound interest formula:

A = P (1 + r/n)^(nt) where: A = the future value of the investment/loan, including interest P = principal investment amount r = annual interest rate (decimal) n = number of times interest is compounded per year t = time the money is invested for, in years

For the interest paid, we calculate:

Interest Paid = A - P

Worked Example

Let's say you deposit $1,000 in a savings account with a 3% annual interest rate, compounded monthly, for 5 years.

Example Calculation

Principal (P) = $1,000

Annual Interest Rate (r) = 3% or 0.03

Compounding Frequency (n) = 12 (monthly)

Time (t) = 5 years

Future Value (A) = 1000 (1 + 0.03/12)^(12*5) = $1,159.75

Interest Paid = $1,159.75 - $1,000 = $159.75

After 5 years, you would have earned $159.75 in interest on your $1,000 deposit.

Frequently Asked Questions

What is the difference between APR and APY?

APR is the annual percentage rate charged or paid, without compounding. APY is the actual annual rate of interest earned, taking into account compounding. APY is always higher than APR for compounding accounts.

How often should interest be compounded for maximum growth?

The more frequently interest is compounded, the more you'll earn over time. Daily compounding typically provides the highest growth, but monthly compounding is common in savings accounts.

Is the interest I earn taxable?

The taxability of interest depends on your country's tax laws and the type of account. In many countries, interest from savings accounts is tax-free, but this may vary.
