Example Data Table

This example uses standard denominator mode with higher values treated as better.

Metric Previous Year Current Year Absolute Change YoY Growth
Revenue 125,000 148,500 23,500 18.80%
Active Users 9,800 11,250 1,450 14.80%
Orders 4,200 4,650 450 10.71%
Site Sessions 310,000 356,500 46,500 15.00%

Formula Used

This calculator applies standard year over year comparison logic and adds optional benchmark and target analysis.

Important: If the previous period value equals zero, percentage growth and growth index are undefined. The calculator still reports absolute change.

How to Use This Calculator

  1. Enter the metric name, units, and period labels.
  2. Add the previous year value and the current year value.
  3. Choose whether higher or lower values represent better performance.
  4. Select the denominator mode. Use absolute mode if negative prior values need magnitude-based comparison.
  5. Optionally enter benchmark and target growth percentages for extra analysis.
  6. Click the calculate button to show results above the form, then export them as CSV or PDF.

FAQs

1) What does year over year growth measure?

It measures the percentage change between a current year value and a prior year value. This helps compare growth, decline, or stability using one consistent metric.

2) Why can YoY growth become undefined?

Percentage growth needs a nonzero baseline. If the previous value is zero, the calculator still shows absolute change, but percentage growth and growth index stay undefined.

3) When should I use absolute denominator mode?

Use absolute mode when prior values may be negative and you want a magnitude-based comparison. Standard mode keeps the original prior value sign inside the denominator.

4) Can I enter negative values?

Yes. Negative values are allowed. Interpretation can change depending on whether you use standard or absolute denominator mode and whether higher or lower values are better.

5) What is benchmark delta?

Benchmark delta is the difference between the calculated YoY growth and a reference growth rate. It shows whether the metric beat or missed a chosen benchmark.

6) What does growth index mean?

Growth index shows the current value as a percentage of the previous value. An index of 120 means the current period is 20% above the prior period.

7) How should I read lower-is-better metrics?

Select the lower-is-better option for measures like churn, defect rate, or cost per acquisition. In that mode, negative growth can represent improvement.

8) Can I export the results?

Yes. Use the CSV button for spreadsheet output and the PDF button for a report-style snapshot of the results section shown above the form.
