Uses positive starting and ending values with no intermediate contributions or withdrawals. Describes smoothed past change, not a forecast.

Your calculation, step by step

No black boxes
  1. CAGR = (20000/10000)^(1/5) − 1.

What if things were different?

Save up to three scenarios, then change your inputs to compare the possibilities.

How to use this calculator

  1. Enter your own values in the labeled fields. Check the units and assumptions before comparing results. Only the fields needed for your selected calculation mode are shown.
  2. Your answer updates automatically. Review the calculation steps to see exactly how it was calculated.
  3. Copy, share, save, or download your result. Saved inputs stay on this device.

How the calculation works

CAGR = (ending / starting)^(1/years) − 1

CAGR smooths a change between two positive endpoint values. It ignores intermediate volatility and cannot correctly isolate investment performance when contributions or withdrawals occurred between the endpoints. Review the units, period and assumptions before comparing scenarios. Displayed values are rounded, while the underlying calculation retains its available precision.

A worked example

Growing from $10,000 to $20,000 over 5 years implies 2^(1/5) − 1 = 14.8698% annual growth.

Reading your result

Use the main result together with its units and supporting figures. Display values are rounded; calculations keep their underlying precision. A change in inputs or assumptions can change the answer. Compare the step-by-step working with your intended use before relying on an estimate.
