How Compound Interest Works

Compound interest means that your interest earnings are added to your principal balance each year, and the next year's interest is calculated on this new amount. This creates a snowball effect where your savings grow exponentially over time.

The formula for compound interest is:

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 this calculator, we assume annual compounding (n=1) and a 4.5% annual interest rate (r=0.045).

Worked Example

Let's say you deposit $1,000 in a savings account with a 4.5% annual interest rate, compounded annually. Here's how your balance would grow over 5 years:

Year	Starting Balance	Interest Earned	Ending Balance
0	$1,000.00	$0.00	$1,000.00
1	$1,000.00	$45.00	$1,045.00
2	$1,045.00	$47.12	$1,092.12
3	$1,092.12	$49.24	$1,141.36
4	$1,141.36	$51.37	$1,192.73
5	$1,192.73	$53.52	$1,246.25

After 5 years, your $1,000 initial deposit would grow to approximately $1,246.25 with a 4.5% annual interest rate.

Frequently Asked Questions

What is compound interest?

Compound interest is when interest is earned on both the initial principal and the accumulated interest of previous periods. This means your money grows exponentially over time rather than linearly.

How does the 4.5% interest rate affect my savings?

A 4.5% annual interest rate means your savings will grow by 4.5% each year, compounded on the previous year's balance. This typically results in better returns than simple interest over time.

Is this calculator accurate for all savings accounts?

This calculator provides an estimate based on annual compounding at 4.5%. Actual results may vary depending on your specific savings account terms, compounding frequency, and other factors.

How often is the interest compounded in this calculation?

This calculator assumes annual compounding, which is common for many savings accounts. Some accounts may compound more frequently (monthly, daily), which would result in slightly higher returns.
