How to Use Calculator on Excel: Formula and Mathematical Explanation

At the heart of using Excel as a calculator are its formulas and functions. A formula in Excel always begins with an equals sign (=). This tells Excel that the cell contains a calculation, not just text or a number. Let’s take the example of calculating percentage change, a common task that demonstrates how to use calculator on Excel effectively.

Percentage Change Formula Derivation

The percentage change formula measures the relative change between an initial value and a final value. It’s calculated as:

Percentage Change = ((Final Value - Initial Value) / Initial Value) * 100

Let’s break this down:

1. Absolute Change: First, we find the difference between the Final Value and the Initial Value (Final Value - Initial Value). This tells us the raw increase or decrease.
2. Relative Change: Next, we divide this absolute change by the Initial Value ((Final Value - Initial Value) / Initial Value). This expresses the change as a fraction of the starting point.
3. Percentage Conversion: Finally, we multiply the result by 100 to express it as a percentage.

In Excel, if your Initial Value is in cell A2 and your Final Value is in cell B2, the formula would be:

=(B2-A2)/A2

You would then format the cell containing this formula as a percentage to display it correctly.
