Quick Reference
The Formula Behind the Tool
1. Simple Percentage Growth Rate (Period-over-Period):
Growth Rate (%) = ((Ending Value – Beginning Value) ÷ Beginning Value) × 100
2. Compound Annual Growth Rate (CAGR):
CAGR (%) = ( (Ending Value ÷ Beginning Value)^(1 ÷ Number of Years) – 1 ) × 100
3. Average Daily Growth Rate:
Daily Growth (%) = ( (Ending Value ÷ Beginning Value)^(1 ÷ Number of Days) – 1 ) × 100
4. Linear Growth Rate (Value per Period):
Linear Growth = (Ending Value – Beginning Value) ÷ Number of Periods
Quick Reference Table (General Growth Terms)
| Term | Formula / Meaning | Example Use Case |
|---|---|---|
| Simple Growth Rate | % Change from start to end | Sales growth in one quarter |
| CAGR | Average yearly % growth over multiple years | Investment growth over 5 years |
| Daily Growth Rate | Average % change per day | Plant biomass growth in 30 days |
| Linear Growth | Absolute change ÷ periods | Weight gain in kg per week |
Variables
- Beginning Value (B): Starting number (e.g., sales, population, size).
- Ending Value (E): Value at the end of the period.
- Years/Days/Periods (T): Time span for growth measurement.
