0.5 APR Savings Account Calculator

This calculator helps you determine how much your savings will grow over time with a 0.5% Annual Percentage Rate (APR) savings account. It accounts for compound interest, which means your earnings earn interest each year.

How to Use This Calculator

To use this 0.5 APR savings account calculator:

Enter the initial deposit amount in the "Initial Deposit" field.
Select the time period for your savings (in years).
Click "Calculate" to see your projected balance.
Review the result and chart showing your savings growth over time.

The calculator uses compound interest to show how your money grows each year. The formula accounts for the 0.5% APR and annual compounding.

Formula Used

The future value of your savings is calculated using the compound interest formula:

Future Value = Initial Deposit × (1 + APR)ᵗ

Where:

Initial Deposit = The amount of money you start with
APR = Annual Percentage Rate (0.5% or 0.005 in decimal)
t = Time period in years

This formula shows how your money grows each year with compound interest.

Worked Example

Let's say you deposit $1,000 in a savings account with a 0.5% APR for 5 years. Here's how the calculation works:

Future Value = $1,000 × (1 + 0.005)⁵

Future Value = $1,000 × 1.005⁵

Future Value ≈ $1,000 × 1.0253

Future Value ≈ $1,025.30

After 5 years, your $1,000 deposit would grow to approximately $1,025.30 with a 0.5% APR savings account.

Interest Rate Comparison

Here's how different interest rates affect your savings over 5 years:

Initial Deposit	0.5% APR	1.0% APR	1.5% APR
$1,000	$1,025.30	$1,051.00	$1,077.15
$5,000	$5,126.50	$5,255.00	$5,385.75
$10,000	$10,253.00	$10,510.00	$10,771.50

This table shows how even small differences in interest rates can affect your savings over time.
