Introducing the Stock CAGR Calculator — Compare Investment Returns the Right Way

A stock that tripled in 10 years and one that tripled in 5 years are very different investments — but simple percentage return doesn’t show you why. Compound Annual Growth Rate (CAGR) does. The new Stock CAGR Calculator computes CAGR, absolute return, and the Rule of 72 for any investment in seconds.

What you get

• CAGR — the annualised growth rate, stated as a percentage.
• Absolute return — the simple percentage gain or loss over the full period.
• Rule of 72 — how many years at this CAGR it would take to double your money.
• Year-by-year sparkline — a simple SVG line chart showing how the investment value grows over the period.

Why CAGR is the right metric

Two investments with the same absolute return but different holding periods have fundamentally different performance profiles. CAGR normalises for time — so you can compare a 10-year holding to a 3-year one, or a stock to a mutual fund to a fixed deposit, all on a single number. It’s the metric fund fact sheets use for exactly this reason.

For a full explanation of the formula, worked examples, common pitfalls, and how to use CAGR alongside the Rule of 72, read our CAGR guide.
