How Savings Interest Is Calculated

The interest earned on a savings account is calculated using the compound interest formula:

Future Value = P × (1 + r/n)^(nt)

Where:

P = Principal amount (initial deposit)
r = Annual interest rate (in decimal)
n = Number of times interest is compounded per year
t = Time the money is invested for, in years

This formula accounts for the compounding effect, where interest is earned on both the initial principal and the accumulated interest from previous periods.

Understanding Compound Interest

Compound interest is the process where interest is calculated on the initial principal and also on the accumulated interest of previous periods. This means your money grows exponentially over time rather than linearly.

For example, if you deposit $1,000 at 5% annual interest compounded annually:

After 1 year: $1,050
After 2 years: $1,102.50
After 3 years: $1,157.63

Notice how the interest grows each year, increasing your total balance.
