Formula Explained

The calculation is based on 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 = annual interest rate (decimal)
n = number of times that interest is compounded per unit t (we use 1 for annual compounding)
t = the time the money is invested or borrowed for, in years

For our 0.05% interest savings account calculator, we use the simplified formula:

Simplified Formula

A = P × (1 + 0.0005)^t

This formula assumes annual compounding of interest. The calculator rounds the final amount to two decimal places for currency display.

Worked Example

Let's walk through an example to see how the calculator works. Suppose you deposit $1,000 in a savings account with 0.05% annual interest, and you want to know how much it will grow to in 5 years.

Enter $1,000 as the initial deposit.
Select 5 years as the time period.
Click "Calculate".

The calculator will show you that your $1,000 will grow to approximately $1,002.50 in 5 years. This is calculated using the formula:

Example Calculation

A = 1000 × (1 + 0.0005)^5

A ≈ 1000 × 1.00250625

A ≈ 1002.50625

Rounded to $1,002.51

This example demonstrates how even a low interest rate can grow your savings over time through compounding.
