CAGR Calculator

Overview

This calculator derives the compound annual growth rate from a starting value, ending value, and elapsed period. It is intended for quick return normalization when a total increase needs to be expressed as a steady annualized rate.

Input Terms

• Beginning Value: Opening amount at the start of the measurement period.
• Ending Value: Closing amount at the end of the measurement period.
• Years: Elapsed term over which the change occurred.

Technical Rationale

CAGR converts a multi-year change into the annual rate that would compound from the beginning value to the ending value over the selected term. The output is most useful for comparing uneven horizons on a like-for-like annual basis.

The total growth output is also shown so users can distinguish the overall change from the annualized rate.

Important Notes

• The calculation assumes a single beginning value, a single ending value, and a positive elapsed term.
• It does not measure money-weighted return or account for interim cashflows.
• Use IRR or a cashflow-aware method where material contributions, withdrawals, or timing effects exist.
