What is CAGR and how it’s calculated
CAGR stands for compound annual growth rate. It is the steady yearly rate at which an investment
would have grown if it rose by the same percentage every year. The formula is
CAGR = (Final / Initial)1/years − 1, expressed as a percentage. For example, if you
invested ₹1,00,000 and it grew to ₹2,00,000 over 5 years, the CAGR is
(2,00,000 / 1,00,000)1/5 − 1 ≈ 14.87%. That means a steady 14.87% a year would
have doubled your money in the same time.
CAGR smooths out the journey into a single average rate, so it ignores interim volatility — the dips and spikes along the way. Two investments can share the same CAGR while one was a calm steady riser and the other a wild rollercoaster. CAGR also assumes no money was added or withdrawn during the period, which makes it ideal for comparing lump-sum investments on an apples-to-apples basis.
