When evaluating the growth trajectory of a systematic investment plan (SIP) in mutual funds, a key metric is the Compounded Annual Growth Rate (CAGR). This financial metric is key to understanding the mean annual growth rate of an investment over a specified time frame longer than one year. It presents a smoothed annual rate of growth, negating the fluctuations that occur during the investment period. Here's an insight into the computation and significance of CAGR in the context of SIPs. 

Key Takeaways 

  • CAGR measures the average yearly growth of SIPs, smoothing out fluctuations in the market. 

  • Calculators like XIRR may be used to calculate the accurate CAGR of numerous SIP payments. 

  • Use CAGR to compare and plan investments, track performance, and anticipate returns. 

  • Know its limitations as CAGR overlooks short-term volatility and risk, therefore use it with other indicators. 

What Is Compounding?  

Compounding is the process, which the value of an investment grows due to the earnings on both the original investment and the accumulated earnings from preceding periods. 

Consider an initial investment of ₹100 with a 5% compound interest rate. In the initial year, the investment accrues ₹5, raising the total value to ₹105. The following year, the interest is calculated on the new total, leading to an interest amount of ₹5.25. This process demonstrates the concept of earning 'interest on interest', which applies to mutual funds, as the profits can be reinvested to earn additional returns.  

The compounding effect increases with the length of the investment period, significantly enhancing the potential for wealth generation. For instance, a mutual fund investment of ₹1 lakh with a 10% compounded return annually would grow to approximately ₹6.7 lakh over two decades. This illustrates the power of compounding, where the original investment has expanded by nearly sevenfold. 

What Is CAGR? 

CAGR stands for Compound Annual Growth Rate. It is a measure of the mean annual growth rate of an investment over a specified period longer than one year. It represents one of the most accurate ways to calculate and determine returns for anything that can rise or fall in value over time. Investors use CAGR to evaluate the performance of different investments or to compare the historical returns of a single investment against other investments or savings accounts.

Calculation of CAGR for SIP  

CAGR for SIP investments calculates the average annual growth rate of your systematic investment plan over time, smoothing out market volatility. It gives a realistic picture of your investment performance by turning irregular cash flows into one growth rate. 

The standard formula is: CAGR is (Ending Value / Beginning Value)^ (1 / Number of Years) – 1 

Direct application of this formula to SIPs may be inaccurate because each payment is invested over different periods. To account for this, investors utilise SIP CAGR calculators or spreadsheets' XIRR function, which takes into account the exact date and amount of each investment. This guarantees that returns are accurately calculated over the investment period. 

Example of CAGR Calculation for SIP

To understand how to calculate CAGR for SIP, consider a simple scenario. Let's suppose you make an investment of ₹15,000 per month in a mutual fund SIP for three years.  

The entire investment amount will be ₹5,40,000. At the end of three years duration, the investment value grows to ₹7,50,000. 

 Using the standard CAGR formula, we get: 

 CAGR = (Ending Value/Beginning Value)^(1 / Number of Years) -1 

 Inserting the values: 

CAGR = (7,50,000 / 5,40,000)^(1/3) – 1 ≈ 11.80% 

However, because each SIP installment is invested at a separate period, this calculation does not accurately reflect the overall return. For correct results, utilise a CAGR return calculator or a spreadsheet's XIRR function, which takes into account the time of each investment. This guarantees that your SIP portfolio's growth rate is precisely calculated. 

Importance of CAGR in SIPs 

CAGR for SIP helps investors understand the average yearly increase of their assets, balancing out market volatility. It enables them to compare mutual funds or financial products on a like-for-like basis, independent of investment timing or volatility. 

Using CAGR, investors may easily estimate CAGR for their SIPs, allowing them to set realistic financial objectives and follow the performance of their systematic investments over time. This statistic is especially useful for analysing long-term SIPs since it takes into account the compounding impact and calculates a geometric average return, providing a dependable estimate of growth. 

Understanding the CAGR for SIP provides investors with a useful tool for measuring, comparing, and planning investments, resulting in more educated financial decisions for wealth development and portfolio growth. 

How Investors Utilise Compound Annual Growth Rate (CAGR) 

Investors commonly utilise CAGR for the following purposes: 

  • Performance comparison: Compare SIP results to other investments or market benchmarks to determine the most consistent alternatives. 

  • Portfolio planning: Determine how current SIP contributions affect long-term wealth building. 

  • Forecasting growth: Determine the possible future value of SIPs using historical returns. 

  • Tracking consistency: Determine the consistency of returns over time while smoothing out short-term volatility. 

  • Simplifying calculations: Tools like a CAGR calculator make this evaluation simple and precise. Use online calculators to calculate CAGR instead of manually applying formulas, saving time and boosting accuracy. 

Smooth Growth Limitations of Compound Annual Growth Rate (CAGR) 

CAGR gives a smooth average growth rate, but it excludes short-term fluctuations in the market. Understanding its limits allows investors to appropriately evaluate the data when planning investments. 

 Key limitations include: 

  • CAGR measures average growth, not yearly changes. 

  • It does not account for market volatility or periods of profit and loss. 

  • Using merely a CAGR calculator may result in a simplistic perspective that ignores the influence of timing and unpredictable cash flows. 

  • CAGR alone does not reflect an investment's risk or stability. 

  • To get a whole view, investors should combine it with additional indicators like standard deviation, portfolio trends, and yearly returns. 

Recognising these constraints allows investors to utilise CAGR as a long-term growth indicator rather than a guaranteed annual return. 

Compound Annual Growth Rate (CAGR) vs. Internal Rate of Return (IRR) 

Investors often evaluate between compound annual growth rate (CAGR) and IRR when assessing SIP and other investment returns. While both quantify growth, they have different approaches to cash flows and timing. The table below outlines the main differences between CAGR vs IRR: 

Feature 

Compound Annual Growth Rate (CAGR) 

Internal Rate of Return (IRR) 

Definition 

Average annual growth rate of an investment over a period 

Discount rate that equates the present value of cash inflows and outflows 

Cash Flow Consideration 

Assumes single initial investment or total value at start and end 

Accounts for multiple, irregular cash flows during the investment period 

Calculation Complexity 

Simple formula-based computation 

Requires iterative calculation or spreadsheet function (XIRR) 

Use Case 

Best for smooth, long-term growth comparison 

Best for investments with multiple inflows and outflows, like SIPs 

Relevance of CAGR in SIPs 

Investors prefer SIPs for their disciplined approach to investing, enabling participation in the market irrespective of its volatile nature. CAGR steps in as a tool to provide a realistic growth estimate, smoothing out volatility by providing a geometric average return. This is especially beneficial in the evaluation of an SIP's performance, where periodic investments are made, often resulting in various amounts of money being invested for different periods. 

Conclusion 

CAGR is a handy gauge to understand your SIP's growth over time. It simplifies the growth rate to an average yearly figure, helping you compare and track your investments efficiently. However, remember it's just one tool and doesn't show the whole picture. To get a precise CAGR for your SIP, use an online CAGR calculator. It's quick, easy, and can give you a clearer view of your investment's performance.

FAQs

CAGR represents the smoothed yearly growth of an investment over time while accounting for compounding. Growth rate can refer to simple, year-on-year changes without smoothing. 

Risk-adjusted CAGR takes into account an investment's volatility or risk when assessing its growth. It allows you to compare the returns of investments with various risk profiles. 

A high CAGR means that the investment increased significantly on average every year over time. It demonstrates strong past success but does not guarantee future results. 

No, CAGR is a geometric average that smooths development. Average return is an arithmetic mean that may not take into account compounding. 

CAGR is influenced by the investment duration, contribution amount, and market changes. Longer periods with steady returns improve CAGR dependability. 

Yes, CAGR can be negative if the investment's ultimate worth is less than its initial value, implying a loss over time annually. A negative CAGR shows a decrease in average yearly growth over the investment period. 

If ₹1,00,000 rises to ₹1,50,000 in 3 years, the CAGR is (1,50,000 / 1,00,000)^(1/3) - 1 = 14.47% each year. This demonstrates that the investment has increased at an average annual rate of 14.47%, smoothing out yearly swings. 

CAGR enables investors to evaluate different assets, analyse SIP success, and plan long-term financial objectives by displaying average annual growth. It also helps with long-term financial planning by projecting future portfolio growth over time.
