Example Data Table
| Scenario | Start Value | End Value | Periods | Total Growth (%) | Annualized Growth (%) |
|---|---|---|---|---|---|
| Dataset A | 1,000 | 1,450 | 5 | 45.00 | 7.72 |
| Dataset B | 2,500 | 3,325 | 4 | 33.00 | 7.41 |
| Dataset C | 800 | 1,120 | 3 | 40.00 | 11.87 |
Formula Used
Growth Factor = Ending Value ÷ Starting Value
Total Growth (%) = ((Ending Value ÷ Starting Value) − 1) × 100
Average Periodic Growth = ((Ending Value ÷ Starting Value)^(1 ÷ Periods) − 1) × 100
Annualized Growth = ((Ending Value ÷ Starting Value)^(1 ÷ Years) − 1) × 100
Growth Factor = (1 + r1) × (1 + r2) × ... × (1 + rn)
This calculator supports both direct value comparison and period-by-period compounding. It also adjusts for an optional comparison rate to estimate real growth.

Frequently Asked Questions
1. What does cumulative growth mean?
Cumulative growth measures the total compounded change from a starting value to an ending value across multiple periods. It captures how gains or losses build over time instead of simply adding percentages together.
2. When should I use manual rates mode?
Use manual rates mode when each period has a different growth percentage. This is useful for modeling volatile datasets, monthly performance series, campaign outcomes, or irregular business changes.
3. What is annualized growth?
Annualized growth converts the full growth path into a standardized yearly rate. It helps compare results across datasets or projects with different time spans and period counts.
4. Why is average periodic growth different from total growth?
Total growth shows the full change over the complete timeline. Average periodic growth shows the equivalent constant rate that would produce the same ending value through compounding.
5. What does the adjustment rate do?
The adjustment rate estimates real growth after accounting for another rate such as inflation, market drag, or benchmark drift. It helps you separate nominal results from adjusted performance.
6. Can this calculator handle negative growth?
Yes. Manual rates mode supports negative percentages, and start-to-end mode will return negative cumulative growth when the ending value is below the starting value.
7. What is the growth index result?
The growth index sets the starting value to 100 and scales the ending value relative to it. This makes comparisons easier across datasets with different original sizes.
8. Why export the schedule table?
The exported schedule supports audits, dashboard sharing, reports, and secondary analysis. It preserves each period’s rate, cumulative value, and percentage growth from the start.
