Frequently Asked Questions

What is SIP (Systematic Investment Plan)?

A Systematic Investment Plan (SIP) is an investment strategy where you invest a fixed amount at regular intervals, usually monthly, into a mutual fund, ETF, or similar asset. In many Western markets, the same concept is known as dollar cost averaging (DCA). SIP reduces timing risk and builds investing discipline through automation.

How is SIP return calculated?

SIP returns use the future value of annuity formula: FV = P x ((1 + r)^n - 1) / r x (1 + r), where P is the monthly contribution, r is the monthly rate of return, and n is the total number of monthly contributions. This calculator also shows total invested capital, returns earned, and optional step-up contributions.

What is $2,000 SIP per month for 20 years at 10%?

Investing $2,000 per month for 20 years at 10% annual return produces approximately $1.52 million. The total invested amount is $480,000 over 240 months, so the remaining value comes from compound growth.

What is the difference between SIP and lump sum?

SIP invests smaller fixed amounts over time, while lump sum invests the full amount at once. SIP lowers timing risk and works well for recurring income. Lump sum can outperform in rising markets, but it exposes more capital immediately.

What is step-up SIP?

Step-up SIP increases your monthly contribution by a fixed percentage every year. For example, a $500 monthly SIP with a 10% annual step-up becomes $550 in year 2, $605 in year 3, and so on. This can materially increase long-term wealth because contributions grow alongside income.

Is SIP better than a fixed deposit?

SIP in equity-oriented investments has historically produced higher long-term returns than fixed deposits, but SIP also carries market risk and no guaranteed outcome. Fixed deposits suit short-term capital preservation, while SIP is typically better for long-term wealth creation.

What is dollar cost averaging?

Dollar cost averaging (DCA) means investing a fixed amount at regular intervals regardless of market price. You buy fewer units when prices are high and more when prices are low. SIP is the same discipline under a different regional name.

How much should I invest in SIP monthly?

A practical starting point is 15% to 20% of monthly income, but the right amount depends on your goals, time horizon, and cash flow. Consistency matters more than starting large. A sustainable monthly amount is better than an aggressive target you cannot maintain.

What is the 15-15-30 rule in SIP?

The 15-15-30 rule is a popular illustration: investing 15,000 per month for 30 years at 15% annual return can potentially build a very large corpus. The exact outcome varies by market and currency, but the rule highlights the power of long-term compounding and disciplined investing.

Can I change my SIP amount?

Yes. Most platforms let you increase, reduce, pause, or resume SIP contributions. Increasing the amount over time is common as income rises. The main benefit is flexibility without needing to abandon the discipline of regular investing.

How to Calculate SIP Returns


The SIP calculator estimates the future value of regular monthly contributions and shows how disciplined investing compounds over time. It also helps compare a regular SIP against a step-up SIP and reverse the calculation when you have a target corpus in mind.

SIP Calculator Formula

The SIP calculator uses the future value of annuity formula to estimate your corpus:

M=P×(1+i)n1i×(1+i)M = P \times \frac{(1 + i)^n - 1}{i} \times (1 + i)

In this formula:

  • MM = Maturity value, or the future value of your SIP investment
  • PP = Monthly SIP contribution amount
  • ii = Monthly rate of return (annual rate / 12 x 100)
  • nn = Total number of monthly installments (years x 12)

Worked Example

Invest $500 per month at 12% annual return for 10 years:

  • Monthly rate: i=0.12/12=0.01i = 0.12 / 12 = 0.01
  • Total months: n=10times12=120n = 10 \\times 12 = 120
M=500×(1.01)12010.01×1.01=$115,019M = 500 \times \frac{(1.01)^{120} - 1}{0.01} \times 1.01 = \$115{,}019

Total invested: $60,000. Returns earned: about $55,019.

SIP Growth Reference Table

This reference shows how $500 per month grows over time at different annual return assumptions:

Years8%10%12%15%
5$36,738$38,929$41,243$44,713
10$91,473$102,422$115,019$138,076
15$173,019$207,929$250,456$337,855
20$294,510$382,828$499,574$783,826
25$475,513$668,691$946,918$1,745,427
30$745,180$1,139,612$1,764,724$3,865,660

Over 30 years, the example invests $180,000 in total. At 12%, the projected gain alone is roughly $1.58 million, which illustrates how strongly time drives SIP growth.

Understanding SIP Calculator Results

  • Total SIP Investment: The total capital contributed through your monthly SIP.
    Calculation: monthly SIP amount x number of months
  • Expected SIP Returns: The growth generated by compounding on top of your invested capital.
    Calculation: total value - total SIP investment
  • Total SIP Value: The projected ending corpus, including both contributions and returns.
    Calculated from the SIP compound-growth formula shown above
  • SIP Return Rate: The percentage gain relative to the total amount you contributed.
    Calculation: ((total value / total SIP investment) - 1) x 100%

SIP vs Lump Sum Investing

FactorSIP / DCALump Sum
Investment StyleFixed amounts at regular intervalsEntire amount invested at once
Capital RequiredSmaller recurring amountsLarge upfront amount
Market Timing RiskLower because entry points are spread outHigher because the whole amount enters at one price
Return PotentialTypically steadier but may lag in strong bull marketsCan outperform when markets rise soon after investing
Best ForRegular income and disciplined investingWindfalls, bonuses, or idle cash already available
Behavioral BenefitAutomates discipline and reduces emotional timing decisionsRequires confidence to invest the full amount immediately
Volatile MarketsBenefits from buying across market dipsCan experience a large drawdown soon after entry

What Is Dollar Cost Averaging (DCA)?

Dollar cost averaging and SIP describe the same core discipline in different markets. In India and Southeast Asia, the term SIP is common. In the United States, United Kingdom, and much of Europe, the same behavior is usually called dollar cost averaging.

In both cases, you invest a fixed amount at regular intervals regardless of market price. You buy fewer units when prices are high and more units when prices are low, which smooths your average purchase cost over time.

Whether you call it SIP or DCA, the math behind compounding is the same. This calculator works for both approaches.

Step-Up SIP Explained

A step-up SIP raises your monthly contribution by a fixed percentage each year. As income grows, contributions grow too, which can materially accelerate wealth accumulation.

Example: $500 per month with a 10% annual step-up at 12% return

  • Year 1: $500/month
  • Year 2: $550/month
  • Year 3: $605/month
  • Year 5: $732/month
  • Year 10: $1,179/month

Impact on 20-year outcomes

  • Fixed SIP ($500/month): ~$499,574
  • Step-Up SIP (10% annual increase): ~$760,000
  • Additional wealth from step-up: ~$260,000 (+52%)

The increase may look modest in the early years, but compounding makes the long-term difference significant.

SIP Calculator Example

For a sample SIP projection with:

  • Monthly SIP amount: $5,000
  • Expected annual return: 12%
  • SIP duration: 5 years

The calculator will show approximately:

  • Total SIP Investment: $300,000 ($5,000×60\$5{,}000 \times 60 months)
  • Expected SIP Returns: ~$103,000
  • Total SIP Value: ~$403,000
  • SIP Return Rate: ~34.33%

Important SIP Calculator Considerations

  • The calculator assumes a constant annual return rate throughout the investment period.
  • The projection does not account for:
    • Taxes on investment gains
    • Fund or platform fees
    • Sequence-of-return risk and market volatility
    • Inflation reducing real purchasing power
  • Actual outcomes will vary with market conditions and the path of returns.
  • Past performance does not guarantee future returns.
