How to Calculate SIP Returns with Simple Steps

A SIP calculator answers a planning question: what might regular contributions become under an assumed rate of return? Your actual return is a different calculation based on contributions, the current or realised value of units, distributions and charges. This guide explains both the illustration and the records you need to assess a real Nepali mutual fund SIP.

Why It’s Not Like a Regular Bank Deposit

A fixed deposit has a stated interest rate and product terms, so its projected payout can be estimated from the bank’s method, tenure and applicable tax. A mutual fund SIP requires a different calculation: each contribution buys units at the applicable NAV, which can change over time.

A mutual fund’s NAV can rise or fall. Monthly contributions therefore buy different numbers of units, and a single assumed growth rate cannot reconstruct your actual transaction history. Use the fund manager’s dated statement to calculate what you invested and what the units are now worth.

The Real-Life Math: A Practical Example

For a simple illustration, suppose you invest NPR 4,000 at the start of each month for ten years. Whether a standing instruction is available depends on the scheme and bank. NIMB Ace Capital’s Sahabhagita Fund FAQ lists payment methods for that scheme; check your own fund manager’s current instructions.

Payment methods vary by scheme. A standing instruction or e-mandate may be available, but confirm the current debit channel and mandate terms with the fund manager and your bank before relying on automatic payments.

Across 120 instalments, the total contribution is NPR 480,000. That is money paid in, not a guaranteed maturity amount. Compare this figure with the hypothetical projection and with your actual fund statement.

• Total money you invested: Rs. 4,80,000 (Rs. 4,000 x 120 months)

For an illustration only, assume you invest NPR 4,000 at the start of each month for 10 years and the value grows at a steady 1% per month (a nominal 12% annual assumption). Contributions total NPR 480,000, and the formula below gives approximately NPR 929,000 before taxes or other deductions. A real fund will not earn a steady monthly rate; NAV can fall, distributions may be paid out rather than reinvested, and the actual outcome may be lower or higher.

The Formula Behind the Scenes: How to Calculate SIP Returns

For the hypothetical projection, use the future-value formula for payments made at the beginning of each month. It applies one assumed monthly rate to every period; it is not a formula for reconstructing the NAV path of a real fund.

The formula looks like this:

Here, $FV$ is your future expected amount, $P$ is your monthly investment amount, $i$ is your expected monthly return rate (annual rate divided by 12), and $n$ is the total number of months.

For actual personal performance, XIRR is one useful money-weighted measure because contributions occur on different dates. Record each contribution as a dated outflow, each cash distribution or redemption as a dated inflow, and the current unit value as a final inflow on the valuation date. As a simpler non-annualised check, if your statement shows NPR 480,000 contributed, NPR 500,000 of units at the selected NAV and NPR 5,000 of cash distributions, the gross gain is NPR 25,000 (about 5.21% of contributions) before applicable exit costs or tax. That 5.21% is not an annual return or XIRR. The calculator’s assumed rate is not your realised return.

How to Calculate SIP Returns: The Easiest Way using our Digital Calculator

Use this site’s SIP calculator to test hypothetical future values from a monthly amount, duration and assumed annual return. It does not read your fund transactions or calculate your realised XIRR. For your actual result, obtain contribution dates, units, distributions, charges and current value from the fund manager’s statement, then calculate a money-weighted return separately.

Simple Steps to Calculate SIP Returns

• Visit our SIP Calculatore Home Page, and see how simple it is to calculate SIP returns by following the instructions below.
• Now by default you are in SIP Mode Section, if not, then tap on SIP from the other menu (Lumpsum, Step UP, & Goal Planner),
• Enter the Desired Amount that you want to invest monthly, under Monthly Investment (NPR),
• Now enter the no. of years you want to invest under, Investment Period option,

• Enter an assumed annual total return for the illustration. This is not the scheme’s dividend percentage: a distribution is only one part of investment return, and NAV can change after it is paid. Test several assumptions rather than treating one rate as a forecast.
• That’s all, here you will get all Calculation result under the Maturity Value (SIP) details. After finishing these steps, you’ve actually walked through the practical process of how to calculate your SIP returns yourself.

The monthly and yearly breakdowns show how the chosen assumptions produce this hypothetical projection. They are not a record of the units or return in your actual scheme.

Wrapping It Up

Use the calculator to compare scenarios, not to confirm a profit. For a real SIP, compare total contributions with the current value of units and any cash received, after charges. A positive or negative outcome depends on the scheme’s NAV path, distributions and timing. Review the official statement before changing your investment plan.
