Formula Used
The savings account profit is calculated using the compound interest formula:
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
Your profit is calculated as A - P.
Worked Example
Let's say you deposit $1,000 in a savings account with an annual interest rate of 3%, compounded monthly, for 5 years.
Example Calculation
P = $1,000
r = 3% = 0.03
n = 12 (monthly compounding)
t = 5 years
A = 1000(1 + 0.03/12)12×5 ≈ $1,159.73
Profit = $1,159.73 - $1,000 = $159.73
After 5 years, you would earn approximately $159.73 in interest on your $1,000 deposit.
