CAGR Calculator
Calculate compound annual growth.
About this calculator
Calculate compound annual growth rate: CAGR = ((final / initial)^(1 / years) − 1) × 100%. It is a smoothed annual rate between two values, assuming no deposits or withdrawals. It does not describe year-to-year volatility or predict future returns. The initial value and duration must be positive; a zero final value represents a total loss. Supports up to 1,000 years.

Frequently asked questions
How does the CAGR Calculator calculator work?
Enter your amounts, rates and terms, and the calculator applies the standard financial formulas to show the outcome, including intermediate figures where they help you understand the result. All arithmetic runs at high precision, so rounding errors do not build up across periods.
When would I use the CAGR Calculator calculator?
Use it when planning a purchase, loan, investment or budget, to compare options before committing, or to sanity-check figures quoted to you. It is an educational tool, not financial advice — confirm important decisions with your provider or a professional.
How accurate are the results?
The formulas are the standard ones used in finance and run at 30 significant digits internally. Real products may differ in fees, compounding conventions and rounding rules, so treat the result as a close estimate rather than a contractual figure.
Can I share a specific calculation with someone else?
Yes. Every value you enter updates the URL, so copying the address bar and sharing the link reopens the exact same calculation for whoever clicks it.
