Formula & methodology
CAGR = (Final Value ÷ Initial Value)^(1 ÷ Years) − 1.
Example: ₹1,00,000 growing to ₹1,80,000 over 5 years — CAGR = (180000/100000)^(1/5) − 1 ≈ 12.47% per year.

Frequently asked questions
How is CAGR calculated?
CAGR = (Final Value ÷ Initial Value)^(1 ÷ Years) − 1 — the constant annual growth rate that would take the initial value to the final value over that period.
Does CAGR account for volatility along the way?
No — it smooths everything into one steady rate. Two investments with wildly different year-to-year swings can have the identical CAGR if they start and end at the same values.
