Percent Variance Calculator

Understanding how values change over time is crucial in finance, business, and everyday decision-making. The Percent Variance Calculator is a simple yet powerful online tool that helps you calculate the percentage increase or decrease between two values. Whether you’re comparing sales figures, tracking expenses, or analyzing performance data, this calculator gives you clear and accurate results in just seconds.

By entering the original and new values, you’ll instantly know how much a number has increased or decreased — both in absolute and percentage terms. The tool also displays whether the change represents an increase, decrease, or no change at all.

🔢 What Is a Percent Variance?

Percent variance represents how much a value has changed relative to its original amount. It’s expressed as a percentage and indicates the scale of growth or decline. The formula used is:

Percent Variance = ((New Value – Original Value) / Original Value) × 100

For instance, if your sales went from $200 to $250, the variance is a 25% increase.

🧭 How to Use the Percent Variance Calculator (Step-by-Step)

Follow these simple steps to calculate the variance between two values:

1. Enter the Original Value
   Input the starting value in the “Original Value” field. For example, if you initially earned $150, type “150.”
2. Enter the New Value
   Add the new or updated figure in the “New Value” field — say, “200.”
3. Click on ‘Calculate’
   Once both fields are filled, click the Calculate button. The calculator begins processing and displays a smooth progress bar for about 3 seconds, mimicking a realistic calculation experience.

   • Absolute Change: The difference between new and original values.
   • Percent Variance: The percentage of change.
   • Change Direction: Whether it’s an increase, decrease, or no change.
5. Copy or Share Your Results
