Formula Explained

The calculation uses 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

This formula calculates the future value of your savings account by accounting for compound interest, which means interest is earned on both the initial principal and the accumulated interest.

Worked Example

Let's calculate the expected earnings from a savings account with the following details:

Principal amount: $5,000
Annual interest rate: 3%
Compounding frequency: Monthly
Time period: 5 years

Using the formula:

Calculation Steps

1. Convert the annual interest rate to a decimal: 3% = 0.03

2. Determine the number of compounding periods per year: Monthly = 12

3. Plug the values into the formula:

A = 5000(1 + 0.03/12)^(12×5)

A = 5000(1 + 0.0025)^60

A ≈ 5000 × 1.1605

A ≈ $5,802.50

After 5 years, you would have approximately $5,802.50 in your savings account, earning $802.50 in interest.

Understanding these factors helps you make informed decisions about your savings strategy.
