How to Calculate SIP Returns?

Summary
SIP returns can be estimated using the Future Value formula or an online SIP calculator by entering the monthly investment amount, expected return and investment tenure.

These calculations show the potential future value but do not guarantee actual returns.For actual SIP performance, XIRR in Excel or Google Sheets is more accurate because it considers different investment dates, cash flows, missed instalments, withdrawals and the final investment value.

How to calculate SIP returns?

A Systematic Investment Plan, also known as SIP, is an investment facility offered by mutual fund houses that allows individuals to invest smaller sums of money at regular intervals in a mutual fund of their choice. It presents a structured way to participate in the market, gradually building significant wealth over the long run by utilising the compounding effect to its potential. 

A SIP calculator is an online tool used to ascertain the estimated future return on an investment.

The formula for the calculation of SIP returns is: 

Future Value (FV) = P ✕ [{❲1 + r)^n – 1} / r] ✕ (1 + r)

Where, 

P = Monthly investment amount

r = Monthly rate of return

n = Number of monthly instalments

Step-by-step Methods to calculate SIP returns

The straightforward walkthrough to calculate SIP returns.

Step 1: Gather Inputs: Review your SIP statement, note the monthly amount, commencement date, number of installments delivered, and current value.

Step 2: Use the Mathematical Formula: Use the FV formula when you are calculating the future value of SIP investments. However, to evaluate the actual performance of your completed investments, XIRR in Microsoft Excel provides a more accurate calculation. 

Obtain the monthly expected return by converting the annual rate of return into a monthly rate, i.e., dividing it by 12.

Step 4: Use a Calculator: The calculation for future value is suitable for estimating potential future wealth. And using the XIRR is suitable for ascertaining the actual return on your SIP, considering the actual cash flows of installments. Also, you can gradually increase the SIP amount, known as the step-up SIP, to increase the overall return.

Step 5: Consider Real-World Variation: However, the SIP return calculations are to measure estimated returns, not guaranteed returns. The actual value of your investment may differ due to factors such as market conditions, the fund’s expense ratios, and certain charges, such as exit loads and capital gains taxes. 

Tools and SIP calculators for Easy Calculation

There are two major ways to calculate the SIP returns. They are mentioned below.

1. Online SIP Calculators: These online SIP calculators make it easy to estimate the potential growth of your investment over time by using the power of compounding. These tools give you an idea of what your investments are worth based on SIP information, including instalment amount, interest rate, and investment duration. These tools help you to look at investment options and make plans for your money in the long term.  

2. MS Excel / Google Sheets: Extended Internal Rate of Return (XIRR) is a tool people use to keep track of changing investment dates and cash flows. This makes it the preferred tool for measuring the actual return on a SIP investment. Since every instalments were made at a different time period having a different current price, measuring with a normal calculator may provide wrong information. 

To calculate the actual returns through XIRR, follow the given steps.

Step 1: List all the dates of the instalment transaction and final redemption of your investment in one column.

Step 2: List the total installments in another column. Put the prefix a minus sign (-) on outflows and a plus sign (+) on inflows on your investment. 

Step 3: Select a new cell and put the formula: =XIRR(values, dates)

Common Mistakes in SIP Returns Calculation

The following are the common mistakes while calculating SIP returns.

1. Impact of missed instalments: Skipping instalments for even 2-3 months may heavily affect your entire corpus, especially in the later years when compounding is at its full potential. 
2. Using simple interest: Some investors consider the simple interest method and call it returns. This may be misleading because it ignores the duration; each instalment has a different investment period.
3. Assume a fixed rate of return. Market-linked SIPs do not deliver the exact return every single year. Using the rate as a fixed assumption is considerable for planning, but it should be treated as an estimate, not a guarantee. 
4. Overlooking expenses: The total returns from funds are usually affected by factors such as expense ratios and taxation. These charges are required to be considered by investors by estimating returns. 

Conclusion

SIP returns are calculated by investors to make informed financial decisions and set practical expectations for building long-term wealth. While the Future Value formula, available on the online calculators, offer a convenient way to estimate the potential growth of SIP investments, tools such as XIRR facilitate a more precise measurement by considering the actual duration and amounts of every transaction. 

Although these returns can be figured out, they are not certain. The market-linked fees and other costs have an impact on SIP returns. To get the most out of SIP investments, it is important to regularly check how the funds are performing and decide whether to invest more. This helps investors stay on track with their goals and get maximum benefits.
