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**

Where:

**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.
