Ask a neighbour how a share did and the answer is usually “50% up!”. That number, the absolute return, hides the most important detail: how long it took. CAGR vs absolute return is the difference between a headline and a fair comparison. This guide shows both formulas with examples, and how tax changes what actually reaches your account.
CAGR vs absolute return: the two formulas
Absolute return = (final value − invested) ÷ invested × 100 CAGR = (final value ÷ invested)^(1 ÷ years) − 1
Include dividends received in the final value for a true total return.
Same gain, different stories
| Holding period | Absolute return | CAGR |
|---|---|---|
| 2 years | 50% | 22.5% |
| 3 years | 50% | 14.5% |
| 5 years | 50% | 8.4% |
| 8 years | 50% | 5.2% |
A 50% gain over 8 years is roughly what a bank fixed deposit might have done, while the same gain in 2 years is excellent. Only CAGR shows that.
What is the rule of 72?
Divide 72 by the yearly return to estimate how many years money takes to double. At 12% CAGR, about 6 years; at 8%, about 9 years. It is an approximation that works best between 6% and 15%.

Adding dividends
Suppose 400 shares bought at ₹250 (₹1,00,000) are sold at ₹330 after 30 months, with ₹4.50 per share of dividends in between. Final value = 1,32,000 + 1,800 = ₹1,33,800. Absolute return 33.8%; CAGR = 1.338^(1 ÷ 2.5) − 1 ≈ 12.35%.
Tax: what you actually keep
- Held 12 months or less: short-term gains taxed at 20%.
- Held more than 12 months: long-term gains taxed at 12.5% on the amount above ₹1.25 lakh in a financial year (shared across all listed equity).
- Dividends: taxed at your slab rate.
- Health and education cess (4%) applies on the tax.
Example: a long-term gain of ₹2,00,000 in a year with no other equity gains. Taxable = 2,00,000 − 1,25,000 = 75,000; tax = 12.5% = ₹9,375, plus cess ≈ ₹9,750.
When CAGR misleads
- It smooths over the ups and downs in between; a 12% CAGR can include a year of −30%.
- For SIPs (many investments on different dates), XIRR is the right measure, not CAGR.
- Past CAGR of any stock says nothing certain about the future.
The share return calculator works out absolute return, CAGR and capital-gains tax from buy and sell prices, dates and dividends. It is for education, not investment advice.
Frequently asked questions
What is the difference between CAGR and absolute return?
Absolute return is the total gain in percent; CAGR is the equivalent steady yearly rate over the holding period.
How do I calculate CAGR?
(final value ÷ invested)^(1 ÷ years) − 1.
Should dividends be included in CAGR?
Yes, add dividends received to the final value for total return.
What is the tax on long-term share gains?
12.5% on gains above ₹1.25 lakh a year for listed equity held over 12 months, plus cess.
Is CAGR right for SIP returns?
No. Use XIRR for investments made on different dates.
