SIP Calculator (Systematic Investment Plan)
Calculate the future value of your monthly SIP investment.
What Is the SIP Calculator (Systematic Investment Plan)?
SIP (Systematic Investment Plan) lets you invest a fixed amount in a mutual fund at regular monthly intervals instead of investing a lump sum all at once. Your money grows through the power of compounding as returns are reinvested over time, and because the investment is automated, SIP is one of the most common ways ordinary investors build long-term wealth in equity and hybrid mutual funds without needing to time the market.
Because each installment is invested at a different point in time, SIP also delivers rupee cost averaging — you automatically buy more mutual fund units when prices (NAV) are low and fewer when prices are high, which smooths out your average purchase cost across market cycles. This is a big part of why SIP is recommended for volatile asset classes like equity mutual funds, where trying to invest a lumpsum at exactly the "right" time is difficult even for professional investors.
If you're deciding between investing a lumpsum you already have versus spreading it out, the SIP vs Lumpsum Calculator compares both approaches directly. Once your income grows and you want your SIP to grow with it, the Step-Up SIP Calculator models a monthly investment that increases by a fixed percentage every year instead of staying flat.
SIP Calculator (Systematic Investment Plan) Formula
FV = P × [(1+r)^n − 1] / r × (1+r)
- P = Monthly investment amount
- r = Monthly rate of return (annual rate ÷ 12 ÷ 100)
- n = Number of months invested
How Is the SIP Calculator (Systematic Investment Plan) Calculated?
Each monthly contribution compounds for a different length of time — the first installment compounds the longest, the last barely compounds at all. This formula sums the future value of every individual installment in one closed-form expression, rather than requiring a month-by-month simulation.
The extra (1+r) multiplier at the end reflects that this is an "annuity-due" calculation — it assumes each month's SIP installment is debited at the start of the month rather than the end, which matches how most mutual fund SIP mandates actually work in practice. Because compounding is exponential rather than linear, the rate and duration you enter matter far more to the final number than most people expect: doubling your monthly amount roughly doubles the future value, but doubling the duration can multiply it several times over, since every extra year compounds on top of everything that came before it.
SIP Calculator (Systematic Investment Plan) Example
Example 1: Investing $10,000/month at 12% annual return for 15 years grows to roughly $5,045,760, from a total investment of $1,800,000 — meaning more than half the final corpus is compounding growth, not your own contributions.
Example 2: A smaller, shorter plan of $5,000/month at 10% for 10 years reaches about $1,032,760 from $600,000 invested — a useful comparison for a medium-term goal like a car or a wedding fund.
Example 3: A larger, longer-horizon SIP of $15,000/month at 14% for 20 years grows to roughly $19,745,194 from just $3,600,000 invested — illustrating how much of a very long-term corpus comes purely from compounding rather than the money you actually put in.

Common SIP Calculator (Systematic Investment Plan) Scenarios
Scenario 1
Planning long-term goals like a child's education or a retirement corpus.
Scenario 2
Comparing how different monthly amounts affect your final wealth.
Scenario 3
Understanding the power of starting to invest early.
Scenario 4
Deciding how much to increase your SIP by after a salary hike.
Scenario 5
Sanity-checking a projection shown to you by a mutual fund distributor or advisor.
Scenario 6
Setting a realistic monthly SIP target for a specific future purchase, like a down payment.
Understanding Your Result
The future value is your total projected corpus at the end of the investment period. The split between "invested amount" and "returns" shows how much of that corpus came from your own contributions versus compounding growth — typically, returns make up a larger share the longer you stay invested.
This is a projection based on the return rate you entered, not a promise — actual mutual fund NAVs move up and down with the market, so your real corpus at any given month could be higher or lower than this smooth, constant-rate estimate. Treat the number as a planning anchor to check your progress against, and revisit it periodically as your income, goals, or market conditions change.
Tips
- Start as early as possible — extra years of compounding matter more than a larger monthly amount started later.
- Increase your SIP amount periodically (see the Step-Up SIP calculator) as your income grows.
- Use a conservative, realistic expected return rather than an optimistic one when planning.
- Review your SIP once or twice a year rather than constantly, to avoid reacting emotionally to short-term market noise.
- Match the fund category (equity, hybrid, or debt) to your actual time horizon — longer goals can typically absorb more equity volatility.
Common Mistakes
- Using an unrealistically high expected return, which overstates the projected corpus.
- Stopping SIPs during market downturns, which defeats the purpose of cost averaging.
- Not accounting for inflation when setting a target future value for a real-world goal.
- Treating the projected future value as guaranteed rather than an estimate based on assumed returns.
- Withdrawing or interrupting a long-term SIP for short-term needs, which resets the compounding clock on that money.
Frequently Asked Questions
What is the minimum SIP amount?
Most mutual funds allow SIPs starting from as low as $500 per month, though this varies by fund house and scheme — some newer small-ticket SIP options go even lower.
Can I stop or pause my SIP anytime?
Yes, SIPs are flexible — you can pause, stop, or modify the amount at any time without penalty in most funds, though repeatedly stopping and restarting undermines the discipline that makes SIP effective.
Does SIP guarantee returns?
No. SIP returns depend on the market performance of the underlying mutual fund. The expected return used here is an estimate, not a guarantee, and actual returns will fluctuate with market conditions.
How is SIP different from a recurring deposit?
Unlike a fixed recurring deposit at a bank, SIP returns are market-linked and can vary year to year, offering potentially higher long-term growth in exchange for more risk and volatility along the way.
Why does the same total investment grow more over a longer period?
Because compounding is exponential, not linear — earlier installments have more time to compound, so extending the duration increases the final value disproportionately compared to simply investing more per month.
Should I use nominal or inflation-adjusted returns?
This calculator uses nominal (unadjusted) returns — for real purchasing-power planning, consider using a lower, inflation-adjusted rate or pairing this with the Inflation calculator to see what your corpus is actually worth in today's money.
Can I increase my SIP amount partway through?
Yes, most mutual funds allow you to modify, pause, or add a new SIP at any time — use the Step-Up SIP calculator if you want to model a planned, regular increase instead of a one-off manual change.
Does SIP always outperform a lumpsum investment?
Not always — in a consistently rising market, lumpsum investing often performs better since the full amount is invested early, while SIP tends to shine more in volatile or declining markets due to rupee-cost averaging.
What does 'power of compounding' mean in the context of SIP?
It means the returns you earn also start earning returns over time, so your invested amount grows at an accelerating pace the longer it stays invested — which is why starting a SIP early matters more than the exact monthly amount.
Can I share my SIP projection as an image?
Yes — tap Share and, on supported devices, your projected future value is shared as a branded image card, not just a text link, so it looks like a real result when it lands in the chat.
How many SIPs can I run at the same time?
There's no fixed limit — many investors run several SIPs across different mutual fund schemes at once, and this calculator can be used separately for each one, or you can combine them mentally by adding up each SIP's monthly amount.
What happens if a SIP installment fails due to insufficient balance?
The fund house typically skips that month's installment (sometimes with a small penalty depending on the bank), and your SIP mandate usually continues automatically the following month without needing to be re-set up.
Is it better to do one large SIP or split it across multiple funds?
This calculator projects a single SIP amount — splitting the same total across multiple funds for diversification doesn't change the combined future value much if the blended return is similar, but it does change your risk profile.
Does this calculator account for the expense ratio charged by mutual funds?
No — the return rate you enter should already reflect the return you actually expect to receive; expense ratios and other fund costs are typically already priced into a fund's published historical returns.
