The savings account calculator is a valuable tool that helps individuals calculate the future value of their investments. It’s particularly useful when you have a lump sum of money, known as the principal amount (P), that you want to invest in a savings account or any interest-earning investment. The calculator takes into account the annual interest rate (r), represented in decimal form, and the number of years (t) you intend to invest your money.
Formula of Savings Account Calculator
The formula used by the savings account calculator is straightforward:
A = P + Prt
- A represents the future value of your investment.
- P is the principal amount, which is your initial deposit.
- r is the annual interest rate expressed in decimal form.
- t is the number of years the money will be invested.
This formula enables you to determine the total amount you’ll have in your savings account or investment after a specified period, taking into account the initial deposit and the interest earned.

Example of Savings Account Calculator
Let’s illustrate how the savings account calculator works with an example. Imagine you have $5,000 (P) to invest in a savings account with an annual interest rate (r) of 0.05 (5%) for 3 years (t). Using the formula:
A = 5000 + 5000 * 0.05 * 3
A = 5000 + 750
= 5750 m²
The future value of your investment would be $5,750. This calculation helps you make informed financial decisions.
