CAGR Calculator 2026: Compound Annual Growth Rate online

What is Compound Annual Growth Rate (CAGR)?

The Compound Annual Growth Rate (CAGR) is one of the most critical metrics used in finance and investing to measure the average annual growth rate of an investment over a specified period of time longer than one year. It represents the smooth, annualized rate at which an asset would have grown if it had grown at a steady, constant compounding rate every year.

In the real world, assets like stocks, mutual funds, and business revenues do not grow in a straight line. They experience volatility, with massive gains in some years and significant losses in others. CAGR filters out this year-to-year volatility, providing investors with a single, clear percentage that represents the annualized rate of return, making it easy to compare different assets on an equal footing.

Why CAGR is the Gold Standard for Return Analysis

When reviewing multi-year investments, simple average returns can be highly deceptive. For instance, consider an investment that grows by 100% in Year 1 and drops by 50% in Year 2.

Deceptive Average: The simple average of the returns is 25% per year $((100\% - 50\%) \div 2)$.
Real-World Outcome: However, if you invested ₹10,000, it grew to ₹20,000 in Year 1, and fell to ₹10,000 in Year 2. Your actual return is **0%**—you made no profit at all.
CAGR Correction: The CAGR for this investment is exactly **0%**, reflecting the true economic reality of your wealth, unlike the simple average.

The CAGR Formula and Mathematical Walkthrough

Calculating the Compound Annual Growth Rate requires the initial value (PV), the final value (FV), and the number of compounding periods (Years). The formula is defined as:

CAGR = ( Ending Value ÷ Beginning Value ) ^ ( 1 ÷ Years ) – 1

To express this as a percentage, multiply the result by 100.

Step-by-Step Mathematical Example:

Suppose you invested **₹1,00,000** in a mutual fund, and after **5 years**, the value of the portfolio grew to **₹2,50,000**. Here is how we calculate the CAGR step-by-step:

Divide ending value by beginning value:
Ratio = 2,50,000 ÷ 1,00,000 = 2.5
Raise the ratio to the power of 1/N (where N = 5 years):
Power = (2.5) ^ (1 ÷ 5) = (2.5) ^ 0.2 ≈ 1.20112
Subtract 1 from the result:
CAGR = 1.20112 - 1 = 0.20112
Multiply by 100 to get percentage:
CAGR % = 20.11%

This means your investment grew at an average compounded rate of **20.11% per year** over the 5-year period.

Absolute Return vs CAGR

It is important to understand when to use **Absolute Return** versus **CAGR**:

Absolute Return: Measures the simple percentage increase in your investment from beginning to end, ignoring the time factor entirely. The formula is: Absolute Return = [(FV - PV) ÷ PV] × 100. In the laptop example above, the absolute return is **150%** (growing from 1 Lakh to 2.5 Lakh).
When to Use: Absolute returns are suitable for short-term investments (held for less than a year) where compounding has no significant role. For multi-year investments, absolute returns are misleading because a 100% return over 2 years is vastly superior to a 100% return over 10 years. CAGR introduces the time dimension, allowing you to see the true annual rate.

Compounded Returns Comparison: CAGR vs IRR vs XIRR

Depending on the cash flow pattern of your investment, different formulas apply:

Metric	Cash Flow Pattern	Best Use Case
CAGR	Single Initial Outflow, Single Maturity Inflow (Lumpsum)	Mutual funds lumpsum returns, stock performance comparison, property value appreciation.
IRR (Internal Rate of Return)	Multiple cash flows occurring at fixed, regular intervals	Monthly insurance premiums, yearly deposits, or regular payouts with equal intervals.
XIRR (Extended IRR)	Multiple cash flows occurring at random, irregular intervals	SIP mutual fund transactions with different dates, multiple buying/selling of shares over time.

Important Limitations of CAGR

While CAGR is an incredibly useful metric, it has two major limitations. First, it assumes a constant, steady rate of growth, masking the actual peaks, valleys, and volatility of the asset. Second, it does not account for intermediate cash flows (such as monthly SIP deposits, dividends, or partial withdrawals). For investments with ongoing cash flows, you must use **XIRR** instead of CAGR.

Frequently Asked Questions (FAQs)

How do I calculate CAGR from 2026 to 2030?

To calculate CAGR between these years, the duration (N) is exactly 4 years (2030 - 2026). Divide your ending value in 2030 by the beginning value in 2026, raise that to the power of 0.25 (1/4), and subtract 1.

Is CAGR the same as Compound Interest?

Yes, mathematically they are identical. Compound interest is the process of earning interest on interest, whereas CAGR is the metric used to describe the average annual rate of that compounding growth after it has happened.

What is a good CAGR over 5 years in India?

A "good" CAGR depends on the asset class and risk. For equity mutual funds and stocks, a 12% to 15% CAGR is considered excellent as it comfortably beats inflation. For low-risk fixed-income debt instruments (FDs, PPF), a 6% to 8% CAGR is standard.

How much CAGR is required to double my money in 3 years?

To double your investment in exactly 3 years, you need a CAGR of approximately 25.99% per annum. (Formula: 2^(1/3) - 1 = 1.2599 - 1 = 25.99%).

Can I use CAGR for SIP calculations?

No. Since a Systematic Investment Plan (SIP) involves multiple cash outflows at different times, CAGR cannot be used because it only calculates returns on a single initial lumpsum. For SIPs, you must use XIRR (Extended Internal Rate of Return) to find your annualized returns.

What is a Reverse CAGR Calculator?

A Reverse CAGR Calculator does the opposite: you input the initial value, the desired CAGR rate, and the time period, and it calculates what the final maturity value of your investment will be in the future.

Does CAGR account for dividends paid out by stocks?

No, standard CAGR calculations strictly look at stock price appreciation (Initial Price vs Final Price). If a stock pays regular dividends, the standard CAGR will underrepresent your total returns. You must add the dividends to the ending value to find the Total Return CAGR.

Is CAGR taxable in India?

CAGR itself is just a metric and is not taxed. However, the capital gains represented by that CAGR are taxable. For equity investments held over 1 year, Long-Term Capital Gains (LTCG) are taxed at 12.5% on gains exceeding ₹1.25 Lakh per financial year (FY 2025-26 rules onwards).
