A SIP calculator is useful when it helps you think in years, not in one-month market noise
Most SIP decisions are not about whether the next month will be up or down. They are about whether the contribution is sustainable, how long the money will stay invested, and what return assumption is reasonable enough for planning without becoming fantasy.
This page helps you project monthly SIP growth, total invested amount, and estimated corpus over time. It is useful for long-range planning, goal sizing, and comparing contribution levels rather than for predicting market outcomes.
Use this for planning, not for promising a return
The return rate you enter is only an assumption. The calculator is strongest when you compare conservative and optimistic scenarios instead of trusting one projected corpus blindly.
What this page helps you decide
- Projects corpus growth from a monthly SIP amount, annual return assumption, and time horizon.
- Separates total money invested from estimated wealth gained so the contribution effect stays visible.
- Helps compare different contribution levels and time horizons before you commit to a goal plan.
How to read a SIP projection
| Point | What you control | What is only an estimate |
|---|---|---|
| Cash flow | Monthly SIP amount | Future return path |
| Discipline | How long you stay invested | Market volatility and drawdowns |
| Outcome | Total invested amount | Final corpus and wealth gain |
What this estimate leaves out
- It does not predict mutual fund returns or guarantee a future NAV outcome.
- It does not account for taxes, fund-level risk, or irregular SIP pauses unless you reflect those in your assumptions.
Monthly investing and expected-return logic
The calculator assumes recurring monthly contributions and applies the chosen annualized return as a projection across the investment period. Earlier contributions get more time to compound, which is why consistency matters almost as much as headline return.
Because the return is only an assumption, the page is best used to compare scenarios such as 10 years vs 20 years or ₹5,000 vs ₹15,000 a month rather than to lock onto one exact corpus figure.
How SIP compounding is projected here
- This tool assumes a fixed monthly SIP and a fixed expected annual return, compounded monthly.
- It does not model taxes, exit loads, fund expenses, or step-up contributions.
- Use the projection as a planning estimate, not as a return promise.
Examples
Long-horizon SIP for wealth building
- Monthly SIP: ₹10,000
- Horizon: 20 years at an assumed 12% annual return
This shows how a moderate monthly contribution can build into a meaningfully larger corpus when time stays on your side.
Shorter goal horizon with higher contribution
- Monthly SIP: ₹25,000
- Horizon: 8 years with a more cautious assumption
Useful when the real question is whether contribution size can offset a shorter investment window for a defined goal.
How to use this SIP Calculator
- Enter the monthly SIP you can realistically sustain, not the maximum number that looks attractive in a projection.
- Test more than one expected-return scenario so you can see how sensitive the outcome is to market assumptions.
- Use the result to size goals, then review the actual fund choice separately.
Common mistakes
- Using an unrealistic return assumption and treating the output like a promise.
- Ignoring the role of investment duration and focusing only on monthly amount.
- Comparing SIP and lump sum without understanding that timing and market path can differ materially.
Edge cases and limitations
- Real returns will vary from the projected path, especially over short periods.
- Missed SIPs, stepped-up SIPs, or tax effects can change the actual outcome from the simplified estimate.
Methodology and review basis

Questions that usually come up
- What is SIP?
- SIP stands for Systematic Investment Plan, where you invest a fixed amount regularly, usually every month, into a mutual fund.
- Does this calculator guarantee the final corpus?
- No. It is a projection tool based on the return assumption you enter. Actual mutual fund performance can be higher or lower.
- Should I use one return assumption or several?
- Several. The page becomes more useful when you compare conservative, base, and optimistic scenarios instead of trusting a single projection.
- Can I compare SIP with lump sum investing?
- Yes. Use this alongside the lump-sum calculator or the SIP-vs-lump-sum guide to see how the two approaches solve different jobs.
- Why does time matter so much in SIP projections?
- Because compounding works hardest on contributions made earlier. A long horizon often changes the result more than small tweaks in assumed return.
