Also known as: SIP growth calculator, mutual fund calculator monthly, SIP return calculator, SIP growth calculator monthly contribution

A SIP (Systematic Investment Plan) lets you invest a fixed amount in mutual funds every month. This calculator shows how your monthly investment can grow over the years with the power of compounding.

How to Use This SIP Calculator

  1. Enter your monthly SIP amount (e.g. ₹5,000).
  2. Enter the expected yearly return (equity funds have historically averaged 10–14%).
  3. Enter the number of years you plan to invest and tap Calculate.

Formula

Maturity = M × ((1+r)ⁿ − 1) ÷ r × (1+r), where M = monthly investment, r = monthly return rate, n = total months.

Example: ₹5,000 per month at 12% for 10 years: invested ₹6,00,000, estimated returns ≈ ₹5,61,695, total value ≈ ₹11,61,695.

Frequently Asked Questions

▶ What is a SIP?
A Systematic Investment Plan (SIP) is a way to invest a fixed amount in mutual funds at regular intervals, usually monthly, instead of investing a lump sum.
▶ Are SIP returns guaranteed?
No. Mutual fund returns depend on market performance. The calculator shows an estimate based on the expected return rate you enter.
▶ What is a good SIP amount to start with?
You can start with as little as ₹500 per month. What matters most is starting early and staying consistent — time in the market beats timing the market.
▶ Should I stop my SIP when markets fall?
Generally no. Continuing your SIP during market dips lets you buy more units at lower prices, which can improve long-term returns.

📖 SIP को और अच्छे से समझें

SIP कैसे काम करती है, कितना रिटर्न मिलता है और कैसे शुरू करें — पूरी जानकारी आसान भाषा में पढ़ें:

Worked example with real numbers

₹10,000 a month for 15 years at an assumed 12% annual return:

ItemAmount
Monthly investment₹10,000
Total invested over 15 years₹18,00,000
Estimated maturity value₹50,45,760
Wealth gained₹32,45,760

Roughly 64% of the final corpus comes from returns rather than your contributions. That proportion rises sharply with time — which is the entire case for starting early rather than starting big.

Why starting age beats SIP amount

All ending at age 60, assuming 12%:

Start ageMonthly SIPYearsTotal investedCorpus at 60
25₹5,00035₹21,00,000≈ ₹3,24,00,000
30₹5,00030₹18,00,000≈ ₹1,76,00,000
35₹5,00025₹15,00,000≈ ₹94,90,000
40₹10,00020₹24,00,000≈ ₹99,90,000

Look at the last two rows. Starting at 40 with double the SIP and ₹9 lakh more invested still barely matches starting at 35 with half the amount. Time is doing work that money cannot replace.

What return should you assume?

SIP returns are not guaranteed. Historical long-run figures for Indian equity funds sit broadly in these ranges, but any individual period can look very different:

Fund typeTypical long-term rangeVolatility
Large cap / index funds10–13%High
Flexi cap11–14%High
Mid cap12–16%Very high
Small cap13–18%Extreme
Hybrid / balanced8–11%Moderate
Debt funds6–8%Low
Plan conservatively. Assuming 12% and getting 10% leaves a real shortfall against a goal. Many planners model 10–11% for equity and treat anything above as a bonus. Past performance genuinely does not predict future returns.

Rupee cost averaging, honestly

Because you invest a fixed amount each month, you automatically buy more units when prices are low and fewer when high. Over a full market cycle this tends to give a better average cost than trying to time entries.

What it does not do is protect you from losses. In a sustained downturn your portfolio value will fall. What it does is stop you from putting everything in at a single unlucky moment, and it removes the need to make a judgement call every month.

The practical implication: continuing your SIP through a market fall is usually the right move, because those are precisely the months when your money buys the most units.

Tax on SIP returns

Each SIP instalment is treated as a separate purchase for holding-period purposes, so units bought in the last twelve months are short-term even if you started years ago. Rates and exemption limits change with each Budget, so verify current figures before planning around them.

Common mistakes

More questions

▶ Are SIP returns guaranteed?
No. Mutual fund returns depend on market performance. This calculator shows a projection based on the return rate you enter, not a promised outcome.
▶ What return rate should I assume?
Many planners use 10–12% for long-term equity funds and 6–8% for debt. Assuming a lower figure and being pleasantly surprised is safer than the reverse.
▶ Should I stop my SIP when markets fall?
Usually not. Falling markets mean each instalment buys more units, which improves your average cost when markets recover. Stopping locks in the disadvantage.
▶ How do I measure my actual SIP return?
Use XIRR, not CAGR. Each instalment has been invested for a different length of time, and XIRR accounts for that properly.
▶ Is SIP better than a lump sum?
SIP suits money you earn monthly and removes timing risk. If you already have a lump sum and a long horizon, investing it at once has historically done slightly better on average — but with more timing risk.
▶ What is a step-up SIP?
One where you increase the monthly amount by a set percentage each year, typically in line with salary growth. Over long periods it produces a substantially larger corpus.
▶ How much SIP do I need to reach ₹1 crore?
At 12% over 20 years, roughly ₹10,000 a month. Over 15 years, about ₹20,000. Our crorepati calculator works this out for your own timeline.
