Growth Chart
The graph shows the historical CAGR path, projected net path, and inflation-adjusted real value trend.
Example Data Table
This sample illustrates a six-year growth path from 10,000 to 17,908 with an annualized growth rate close to 10.20%.
| Year | Illustrative Value | Notes |
|---|---|---|
| 0 | 10,000.00 | Starting value |
| 1 | 11,020.00 | After one year at about 10.20% |
| 2 | 12,144.04 | Compounded growth continues |
| 3 | 13,382.73 | Mid-period value |
| 4 | 14,747.77 | Fourth year estimate |
| 5 | 16,252.04 | Fifth year estimate |
| 6 | 17,908.00 | Ending value |
Formula Used
1) Compound Annual Growth Rate
CAGR = (Ending Value / Beginning Value) ^ (1 / Years) - 1
This converts total growth over several years into one annualized rate.
2) Real CAGR
Real CAGR = ((1 + CAGR) / (1 + Inflation Rate)) - 1
This removes the effect of inflation to estimate purchasing-power growth.
3) Net CAGR After Drag
Net CAGR = ((1 + CAGR) × (1 - Annual Drag)) - 1
This applies an annual fee or drag for future projection analysis.
4) Continuous Annual Log Growth
Log Growth = ln(Ending Value / Beginning Value) / Years
This is helpful when comparing growth using continuous compounding language.
5) Years to Reach a Target
Years to Target = ln(Target / Beginning Value) / ln(1 + CAGR)
This estimates how long growth may take if the annualized rate stays stable.
How to Use This Calculator
- Enter the starting value and ending value for the observed period.
- Enter the number of years between the two values.
- Add inflation to estimate real growth instead of nominal growth.
- Add annual fee or drag if you want more conservative projections.
- Choose forecast years to extend the trend beyond the observed data.
- Optionally enter a target value to estimate the years required.
- Select yearly, quarterly, or monthly frequency for chart detail.

FAQs
1) What does CAGR measure?
CAGR measures the constant annual rate that would turn a beginning value into an ending value over a set time period. It smooths uneven year-to-year changes into one annualized growth figure.
2) Why is CAGR useful in statistics?
It helps compare growth across datasets with different durations or scales. Analysts use it for investment series, population trends, revenue growth, and sample-based time progression.
3) Does CAGR show yearly volatility?
No. CAGR hides intermediate fluctuations and only reflects the annualized rate implied by the start and end values. Use it with raw yearly data when volatility matters.
4) What is the difference between nominal and real CAGR?
Nominal CAGR uses raw values only. Real CAGR adjusts that annualized rate for inflation, giving a clearer picture of purchasing-power growth or inflation-adjusted performance.
5) When should I include annual drag or fees?
Include drag when projecting future values that may be reduced by management fees, system losses, operating costs, or other recurring annual deductions.
6) Can CAGR be negative?
Yes. If the ending value is below the beginning value, CAGR becomes negative. That indicates an annualized decline over the measured period.
7) Is CAGR better than average yearly change?
They answer different questions. Average yearly change shows linear annual value movement, while CAGR shows the equivalent compounding rate across the full period.
8) Why does the calculator include a target estimate?
The target estimate helps planning. It tells you how many years the starting value may need to reach a chosen goal if the calculated CAGR continues.
