Formula Used

The calculator uses the following formulas to calculate your savings account growth:

Simple Interest Formula

A = P(1 + rt)

Where:

A = Final amount
P = Principal amount (initial deposit)
r = Annual interest rate (in decimal)
t = Time period (in years)

Compound Interest Formula

A = P(1 + r/n)^(nt)

Where:

A = Final amount
P = Principal amount (initial deposit)
r = Annual interest rate (in decimal)
n = Number of times interest is compounded per year
t = Time period (in years)

The calculator assumes that interest is compounded annually unless specified otherwise.

Worked Example

Let's calculate the growth of $1,000 over 5 years with a 3% annual interest rate using both simple and compound interest methods.

Simple Interest Calculation

Using the simple interest formula:

A = $1,000(1 + 0.03 × 5) = $1,000 × 1.15 = $1,150

Total interest earned: $1,150 - $1,000 = $150

Compound Interest Calculation

Using the compound interest formula with annual compounding:

A = $1,000(1 + 0.03/1)^(1×5) = $1,000 × 1.159274 = $1,159.27

Total interest earned: $1,159.27 - $1,000 = $159.27

Notice that compound interest results in slightly more money than simple interest over the same period.

Frequently Asked Questions

What is the difference between simple and compound interest?

Simple interest is calculated only on the original principal amount, while compound interest is calculated on the original principal plus any accumulated interest. This means compound interest can grow your money faster over time.

How often is interest compounded in a savings account?

Most savings accounts compound interest annually, but some may offer more frequent compounding periods like quarterly or monthly. Check with your bank for specific details.

What is the difference between APY and APR?

APY (Annual Percentage Yield) is the real rate of return considering compounding, while APR (Annual Percentage Rate) is the nominal interest rate before compounding. APY is always higher than APR for the same account.

Can I withdraw money from a savings account at any time?

Yes, you can typically withdraw money from a savings account at any time, but some accounts may have withdrawal limits or fees. Check your account terms for specific details.
