About this calculator

CAGR is the constant annual rate that takes a starting value to an ending value over a given time: CAGR = (end/start)^(1/years) − 1.

Formula

CAGR = (end/start)^(1/t) − 1

Example

10,000 → 18,000 over 5 years → CAGR ≈ 12.47%

Assumptions
  • Fixed rates and terms as entered; no fees or taxes unless modeled.
  • Calculation runs locally in the browser.
Units
  • Currency units as entered (dimensionless rates in %)
Boundary conditions
  • Zero or missing required fields yield zero or empty results.
  • Negative inputs are treated as zero.
Example
10,000 → 18,000 over 5 years → CAGR ≈ 12.47%
Validation cases
  • 10000 → 18000 · 5 yr → ≈ 12.47%
  • 100 → 100 · 3 yr → 0%
  • 1000 → 2000 · 1 yr → 100%
