Formula Explained

The calculation for savings account interest 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 = the principal investment amount (the initial deposit or loan amount)
r = the annual interest rate (decimal)
n = the number of times that interest is compounded per year
t = the time the money is invested or borrowed for, in years

For monthly compounding, n = 12. The calculator uses this formula to provide accurate results based on your inputs.

Worked Example

Let's say you deposit $1,000 in a savings account with an annual interest rate of 3%, compounded monthly, for 2 years.

Principal (P) = $1,000
Annual interest rate (r) = 3% or 0.03
Compounding frequency (n) = 12 (monthly)
Time (t) = 2 years

Using the formula:

A = 1000(1 + 0.03/12)^(12×2)

A = 1000(1 + 0.0025)^24

A ≈ 1000 × 1.061678

A ≈ $1,061.68

After 2 years, your savings account will be worth approximately $1,061.68, with $61.68 in interest earned.

Can I withdraw money from my savings account without penalty?

Most savings accounts allow free withdrawals, but some may have restrictions or fees for excessive withdrawals. Check your account terms for specific details.
