CAGR Calculator — Free Investment return Calculator

Measure Your Investment's True Annualised Growth Rate

CAGR reveals the average annual return of an investment over a specified period.

The Compound Annual Growth Rate (CAGR) is the most widely used metric to measure an investment's average annual growth over a period longer than one year. Unlike simple average returns, CAGR accounts for compounding and provides a smoothed annualised rate that tells you exactly how much your investment has grown each year on average. This calculator helps you compute CAGR instantly from beginning value, ending value, and time period.

How to Use the CAGR Calculator

All you need are three numbers: the starting value, the ending value, and the number of years. The calculator does the rest.

1. Enter Beginning Value: Input the initial value of your investment at the start of the measurement period. Example: ₹
2. Enter Ending Value: Input the current or final value of your investment at the end of the period. Example: ₹
3. Enter Time Period (Years): Enter the number of years between the beginning and ending values. Example: 5 years
4. Get Your CAGR Result: The calculator shows the CAGR as a percentage. Compare this against benchmarks and other investments to evaluate performance. Example: CAGR: 12.47%

Pro tip: Always compare CAGR against a relevant benchmark. A 15% CAGR looks great, but if the S&P 500 returned 18% over the same period, your investment actually underperformed the market.

Key Benefits of Using CAGR

CAGR eliminates the noise of year-to-year volatility and gives you a single, comparable number.

• Measure True Returns — CAGR accounts for compounding and gives the geometric average annual return, which is more accurate than a simple arithmetic average for investment returns.
• Compare Investments Fairly — Compare the performance of different investments — stocks, mutual funds, real estate — on an equal footing, regardless of their volatility or time period.
• Evaluate Performance Objectively — Use CAGR to assess whether your portfolio manager, mutual fund, or trading strategy has delivered value above the market benchmark.

Real-World Example: Jane Evaluates Her Portfolio

Jane

Jane is a 38-year-old portfolio manager evaluating her personal investment portfolio's performance over the past 6 years.

Beginning Value: ₹

Ending Value: ₹

Time Period: 6 years

Jane invested ₹ in a mix of US and international equity ETFs in January 2019. By January 2025, her portfolio was worth ₹. She wanted to know the true annualised return to compare against the S&P 500's performance over the same period. Using the CAGR calculator, she found her portfolio's annualised growth rate.

CAGR: 10.80%

During the same 6-year period, the S&P 500 had a CAGR of approximately 11.5%. Jane's portfolio slightly underperformed, largely due to her international allocation, which lagged US markets. This insight helped her decide to increase US exposure.

Jane rebalanced her portfolio to 75% US equities and 25% international. She now uses CAGR analysis annually to track performance against benchmarks and makes data-driven adjustments.

Formula & Key Concepts

CAGR is mathematically straightforward but conceptually powerful. Here is how it works.

EV Ending value (final value of the investment) (e.g. ₹). BV Beginning value (initial value of the investment) (e.g. ₹). n Number of years in the investment period (e.g. 5 years).

Compound Annual Growth Rate Formula: CAGR = (EV / BV)^(1 / n) - 1

CAGR Comparison Across Different Investments

Compare the CAGR of various asset classes over different time periods. Past performance does not guarantee future results, but this gives context for realistic expectations.

Equities have historically delivered the highest CAGR over long periods, but with higher volatility. A diversified portfolio blending asset classes typically achieves 6–9% CAGR with reduced drawdown risk. Your ideal mix depends on your time horizon and risk tolerance.

Common Misconceptions About CAGR

CAGR is widely used but also widely misunderstood. Here are the most common pitfalls.

• Misconception: CAGR represents the actual return each year.. Reality: CAGR is a smoothed average. The actual returns likely varied significantly year to year. A 12% CAGR could mean +30% one year and -5% the next. Expecting consistent yearly returns leads to disappointment and poor decisions during volatile periods.
• Misconception: A higher CAGR always means a better investment.. Reality: Higher CAGR often comes with higher risk and volatility. A fund with 15% CAGR may have dropped 40% in a bad year, while a fund with 10% CAGR may have been much more stable. Risk-adjusted returns (like the Sharpe ratio) should be considered alongside CAGR for a complete picture.
• Misconception: CAGR and absolute return are the same thing.. Reality: Absolute return is the total percentage gain over the entire period. CAGR annualises that gain. A 50% absolute return over 5 years is just 8.45% CAGR. Unscrupulous marketers sometimes highlight high absolute returns without mentioning the long time period. CAGR gives the honest annualised picture.

Frequently Asked Questions

What is a good CAGR for an investment?

A "good" CAGR depends on the asset class and market conditions. For US equities, any CAGR above the S&P 500 average (8–10% long-term) is excellent. For bonds, 3–5% is typical. The key is comparing against an appropriate benchmark.

Can CAGR be negative?

Yes. If the ending value is less than the beginning value, CAGR will be negative, indicating a loss over the period. This can happen with any investment, especially over short time horizons.

Is CAGR the same as IRR (Internal Rate of Return)?

No. CAGR assumes a single initial investment with no intermediate cash flows. IRR accounts for multiple cash flows in and out over time. For simple buy-and-hold investments, CAGR and IRR are the same.

Does CAGR account for dividends and interest?

CAGR accounts for dividends and interest only if they are included in the ending value. If you reinvested dividends, they are reflected. If you withdrew them, they are not.

Tips & Tricks for Using CAGR

Master CAGR with these expert insights to become a more informed investor.

• Always Use the Same Time Period for Fair Comparison — When comparing two investments, ensure the time periods are identical. Market conditions vary significantly across years, making different-period comparisons misleading. Comparing a fund's 3-year CAGR (which includes a bull market) with another fund's 3-year CAGR (which includes a bear market) is not meaningful.
• Use Rolling CAGR to Assess Consistency — Instead of a single point-to-point CAGR, look at rolling 3-year or 5-year CAGRs over time. This reveals whether performance is consistent or driven by a single good year. A fund with consistent 8–10% rolling 5-year CAGR is preferable to one that swings from 2% to 18%, even if both average 10%.
• Combine CAGR with Risk Metrics — CAGR tells you return but not risk. Pair it with standard deviation, maximum drawdown, or Sharpe ratio for a complete performance picture. Fund A: 12% CAGR, 25% max drawdown. Fund B: 10% CAGR, 10% max drawdown. If you are risk-averse, Fund B may be the better choice.

Your Next Steps

Now that you understand CAGR, here is how to apply it to your investment analysis.

• Calculate CAGR for All Your Investments — Gather beginning values, current values, and dates for each of your investments. Run them through the CAGR calculator to see your true annualised returns.
• Compare Against Relevant Benchmarks — Look up the CAGR of appropriate benchmarks (S&P 500, NASDAQ, Nifty 50, etc.) over the same period. Determine which investments are adding value vs lagging.
• Make Data-Driven Portfolio Adjustments — Use CAGR insights to rebalance your portfolio. Reduce or eliminate consistently underperforming holdings. Increase allocation to investments with strong risk-adjusted CAGR.
