- A stock, a fund, a house or an FD
- Compared on equal terms

- Growth₹1.5 L60%
The same growth, smoothed into years
- You put in
- Growth at 13.99% a year
- At 7% instead
Real investments zig-zag. CAGR is the steady yearly rate that would have taken you from start to end, so each bar is where that steady path stands.

What this means
- 150% in total is 13.99% a year, not 21.4%.
Why?
Dividing the total return by 7 years ignores compounding: each year's growth builds on the last, so a smaller yearly rate gets you to the same place. CAGR is that smaller, steady rate.
- Beat 7% a year by 6.99 points, ₹89.4K more than it would have made.
Why?
₹1,00,000 at 7% for 7 years grows to ₹1,60,578. Compare like with like: a fixed deposit's interest is taxed every year, while equity gains are taxed only when you sell.
- 7.53% a year after inflation.
Why?
With prices rising 6% a year, ₹2,50,000 at the end buys what ₹1,66,264 bought at the start.
- After tax on selling it as an equity fund, 13.99% a year becomes 13.77%: ₹3.3K goes in tax.
Why?
Gains on units held a year or more pay 12.5% above ₹1.25 L a year. Both add 4% cess. A fixed deposit's interest is taxed at your slab every year instead, and other assets follow other rules.
- At 14%, money doubles every 5.3 years.
Why?
Quick check with the Rule of 72: 72 ÷ 14.0 ≈ 5.1 years.

How it's calculated
CAGR is the steady yearly rate that turns the starting value into the ending value:
CAGR = (End ÷ Start)1/years − 1
Return after inflation divides out price rises instead of subtracting them: (1 + CAGR) ÷ (1 + inflation) − 1. CAGR fits a single investment. If you added or took out money along the way, use XIRR.
Tax if you sell (equity funds). Units held a year or more pay 12.5% on gains above ₹1.25 L a year; units held under a year pay 20%. Both add 4% cess.
Tax = max(0, gain − ₹1.25 L) × 12.5% × 1.04
You keep = value − tax
After-tax return = (you keep ÷ put in)1/years − 1
