What this calculator helps you do
Convert beginning value, ending value, and elapsed years into a smoothed annual growth rate. The calculation runs entirely in your browser; SENNA Finance does not receive the values entered into this tool.
Worked example
Using the default example—beginning value of $10,000, ending value of $18,500, number of years of 5 years—the calculator returns compound annual growth rate of 13.09%; absolute change: $8,500.00; total growth: 85.00%. Change the assumptions to match your own case rather than relying on the example.
Formula and calculation basis
Inputs are converted to the periodic units required by the formula. Results are calculated with full JavaScript numeric precision and rounded only for display.
How to interpret the result
CAGR describes the constant annual rate that would connect the two values. It hides volatility and the path taken between them.
Common mistakes to avoid
- Using CAGR when there were significant cash additions or withdrawals.
- Treating the smoothed rate as the return earned every year.
- Using zero or negative beginning values in a standard CAGR formula.
Limits and assumptions
CAGR is appropriate for positive beginning and ending values with no intermediate cash-flow adjustment.
Outputs are estimates, not contractual quotations, regulated disclosures, tax advice, investment advice, or a substitute for professional review.
Frequently asked questions
Does CAGR show volatility?
No. It compresses the entire period into one constant annualized rate.
Can CAGR compare investments?
It can help compare growth over equal or different periods, but risk and cash flows still matter.
What if I made deposits?
Use an IRR-style cash-flow analysis instead of simple CAGR.
