Can this calculator handle both increases and decreases?

Yes, the tool outputs a positive percentage for an increase and a negative percentage for a decrease between the initial and final values.

What formula does the calculator use?

It divides the difference between the final and initial values by the initial value, then multiplies by 100 to express the result as a percentage.

Is the result affected by the order of the values entered?

Yes, the initial value must be entered first and the final value second; reversing them will produce a negative percentage or an incorrect result.

Can I use this for financial calculations like profit margin?

Yes, the calculator is suitable for finance-related percentage changes, such as tracking revenue growth or cost adjustments, as long as the starting and ending figures are known.
