The calculator uses compound interest to show how your money grows over time with a 3.5% annual interest rate. Compound interest means you earn interest not just on your initial deposit, but also on the accumulated interest from previous periods.

Formula Explained

The calculation uses the compound interest formula:

Future Value = Initial Deposit × (1 + Interest Rate)^Years

Where:

Initial Deposit = The amount of money you start with
Interest Rate = 3.5% (0.035) per year
Years = The number of years the money will grow

This formula shows how your initial deposit grows over time with compound interest. The more years you save, the more your money will grow due to compounding effects.

Worked Example

Let's say you deposit $1,000 in a savings account with a 3.5% annual interest rate. Here's how your money would grow over 5 years:

Year	Balance
0	$1,000.00
1	$1,035.00
2	$1,071.35
3	$1,109.08
4	$1,148.23
5	$1,188.84

After 5 years, your $1,000 initial deposit would grow to approximately $1,188.84 with a 3.5% annual interest rate.

Frequently Asked Questions

What is compound interest?

Compound interest is when interest is calculated on the initial principal and also on the accumulated interest of previous periods. This means your money grows faster over time compared to simple interest.

How often is the interest compounded?

This calculator assumes annual compounding, which is common for savings accounts. Some accounts may compound more frequently, which would result in slightly higher growth.

Is this calculator accurate for all savings accounts?

This calculator provides an estimate based on a 3.5% annual interest rate. Actual savings account interest rates may vary depending on your financial institution and account terms.
