How This Calculator Works
Enter any existing lump sum, your monthly SIP amount, the expected annual return, and the investment period. The calculator compounds the contributions monthly and shows the projected corpus and how much is investment growth versus your invested amount. SIP applies rupee-cost averaging — investing a fixed sum regularly regardless of market level.
The Formula
Future Value with Regular Contributions
P = starting amount, PMT = monthly contribution, r = monthly rate (annual ÷ 12), n = number of months
Worked Example
A ₹10,000 monthly SIP for 10 years at an assumed 12% grows to about ₹23.0 lakh (₹2,300,387) — of which roughly ₹11.0 lakh is growth on ₹12 lakh invested. A SIP (Systematic Investment Plan) automates investing a fixed amount into a mutual fund at regular intervals (usually monthly). It's wildly popular in India because it instils discipline, applies rupee-cost averaging (you buy more units when prices are low and fewer when high), and harnesses compounding over long horizons — turning modest monthly amounts into a large corpus.
Key Insight
The SIP is the cornerstone of retail investing in India, and understanding it helps set realistic expectations. The mechanics: you invest a fixed sum (e.g. ₹10,000) monthly into a chosen mutual fund, buying units at the prevailing NAV — so over time you average your purchase price (rupee-cost averaging), which smooths out market volatility and removes the need to time the market. The two big drivers of the outcome are the monthly amount and time: because of compounding, starting early and staying invested matters far more than the exact amount, and the final years of a long SIP add disproportionately to the corpus. Important caveats this estimate simplifies: the 12% commonly used for equity SIPs is an assumption, not a guarantee — actual returns vary year to year and can be negative over short periods, so equity SIPs suit long horizons (5+ years, ideally 10+); the calculator uses a constant return, while real markets are volatile (the realised value could be higher or lower); and it ignores the fund's expense ratio (which reduces returns), any exit load for early redemption, and tax — equity fund gains attract capital gains tax (LTCG above a threshold, STCG if sold within a year), and debt funds are taxed differently. SIPs can be in equity funds (higher expected return, higher risk — assume ~10–12%), debt funds (lower, steadier — assume less), or hybrid. A 'step-up SIP' (increasing the monthly amount each year, e.g. with your income) grows the corpus substantially more. This is a planning estimate; for net wealth, factor expense ratios and capital gains tax, use a conservative return for safety, and remember SIP's real power is the discipline and compounding of staying invested through market cycles.
Step-up SIP: contributions that rise every year
A 'step-up' or 'top-up' SIP raises the monthly contribution by a fixed percentage at the start of each year. The intuition is simple — your salary tends to rise, so your SIP should too. The compounding impact is large.
Starting at ₹10,000/month for 15 years at a 12% return, a regular SIP grows to about ₹49.96 lakh. The same SIP with a 10% annual step-up grows to about ₹85.98 lakh — a 72% increase — while only requiring the contribution to reach roughly ₹38,000/month by year 15, in step with typical salary growth. A 15% step-up reaches about ₹1.17 crore; 20% reaches ₹1.63 crore. The reference table below shows the full ladder.
Most Indian platforms (Groww, Zerodha Coin, Kuvera, ET Money) let you schedule a step-up SIP directly. The mathematical formula sums each year's annuity stream compounded forward, so it does not have a single closed form like the regular SIP — but the table is the practical answer.
Reverse SIP: how much per month to reach a target
The reverse direction — given a goal corpus, how much must you invest monthly? — is just the SIP formula inverted. To reach ₹1 crore in 20 years at 12%, you need about ₹10,109 a month. To reach the same goal in 15 years, you need ₹20,017/month. In 10 years, ₹43,471/month.
Two practical points: the required monthly amount is highly sensitive to the years available, so starting early is by far the cheapest lever; and the assumed return matters — at 10% (not 12%) over 15 years, the same ₹1 crore goal needs ₹24,127/month instead of ₹20,017.
Tax on SIP gains: LTCG and STCG on equity mutual funds
SIP returns from equity mutual funds (funds with at least 65% equity allocation) are taxed under the capital-gains regime, with each individual SIP instalment treated as its own purchase for the holding-period clock.
Long-term capital gains (LTCG, holding > 12 months) on equity funds are taxed at 12.5% on gains above an annual ₹1.25 lakh exemption — recent budget changes raised both the rate (from 10%) and the exemption (from ₹1 lakh).
Short-term capital gains (STCG, holding ≤ 12 months) on equity funds are taxed at 20% — also raised from the previous 15%.
Debt mutual fund gains (less than 65% equity) are taxed entirely at the investor's slab rate — there is no longer a LTCG concession for them following the 2023 reform.
Practically, because each SIP instalment is taxed separately on its own holding period, the early instalments qualify for LTCG faster than the last instalments; long-horizon SIPs end up paying almost entirely the LTCG rate on most of the corpus.
ELSS: SIPs that save tax under Section 80C
Equity Linked Savings Schemes (ELSS) are equity mutual funds eligible for a Section 80C deduction of up to ₹1.5 lakh per financial year — the same cap shared with PPF, EPF, life insurance premiums, etc. Each ELSS SIP instalment is locked in for 3 years from its date of investment (the shortest lock-in among 80C options).
ELSS gains are still taxed under the equity-fund LTCG regime at 12.5% above ₹1.25 lakh per year on redemption. The combination — tax deduction on the way in, plus equity growth, plus the lowest lock-in among 80C options — is the reason ELSS is a popular default for tax-saver investors in the old tax regime. Under the new tax regime (which forgoes most deductions), the 80C advantage of ELSS disappears, so the choice between ELSS and a regular equity fund SIP depends on which regime you file under.
SIP vs lumpsum: which is better
If you already have the corpus and the market is at fair value, mathematically a lumpsum tends to outperform an equivalent SIP because all of it compounds from day one. Studies of historical Indian equity returns show lumpsum winning slightly on average over 15+ year horizons.
But SIPs win on behaviour and risk management. They enforce regular saving (you don't need willpower), they average the entry price through volatile markets (rupee-cost averaging), and they avoid the timing risk of committing a large amount just before a fall. For most investors building wealth from salary income, the question is not 'SIP or lumpsum' — it is 'SIP'.
A common hybrid: when a windfall (bonus, RSU vest, inheritance) arrives, deploying it as a STP (Systematic Transfer Plan) — parked in a liquid fund and moved into an equity fund over 6–12 months — combines the timing-risk benefit of a SIP with the speed of a lumpsum.
Regular SIP vs Step-up SIP — outcome comparison
Starting monthly contribution: ₹10,000. Horizon: 15 years. Assumed return: 12% p.a. compounded monthly. The third column shows how much the monthly contribution has grown to by year 15.
| Annual step-up | Future value at year 15 | Monthly amount in year 15 | vs regular SIP |
|---|---|---|---|
| 0% (regular SIP) | ₹49,95,802 | ₹10,000 | baseline |
| 5% per year | ₹64,66,091 | ₹19,799 | +29% |
| 10% per year | ₹85,97,871 | ₹37,975 | +72% |
| 15% per year | ₹1,17,18,044 | ₹70,757 | +135% |
| 20% per year | ₹1,63,11,291 | ₹1,28,521 | +227% |
Returns are illustrative, not guaranteed. Actual mutual-fund returns vary by fund, period, and the SIP timing within each month. Step-up percentages are applied at the start of each year.
SIP vs Lumpsum — practical trade-offs
Both routes target the same corpus, but they suit different situations. For most investors using salary income, SIP wins on behavioural and timing-risk grounds; for windfalls, lumpsum or a hybrid STP is usually best.
| Aspect | SIP (Systematic Investment Plan) | Lumpsum |
|---|---|---|
| Capital required upfront | Just the first instalment | The full amount |
| Mathematical edge (rising market) | Lower — later instalments compound less | Higher — all of it compounds from day one |
| Timing risk | Low — averaged across many entry prices | High — single entry price |
| Discipline / behaviour | Strong — automated, removes willpower | Weak — requires one-off decision |
| Best for | Salary earners, long horizons, volatile markets | Windfalls when markets are fairly valued |
| Tax treatment | Each instalment a separate holding-period | Single holding-period clock |
Frequently Asked Questions
How is SIP future value calculated?
Each monthly SIP contribution compounds at the expected return (annual rate ÷ 12 per month). A ₹10,000 monthly SIP for 10 years at 12% grows to about ₹23.0 lakh, of which roughly ₹11.0 lakh is growth on ₹12 lakh invested — before expenses and tax.
What is a SIP?
A Systematic Investment Plan — investing a fixed amount into a mutual fund at regular intervals (usually monthly). It automates investing, applies rupee-cost averaging (buying more units when prices are low, fewer when high), and harnesses long-term compounding. It's the most popular way Indians invest in mutual funds.
Is the 12% return guaranteed?
No. The ~12% commonly used for equity SIPs is an assumption based on long-run history, not a guarantee — actual returns vary year to year and can be negative over short periods. This calculator uses a constant return, but real markets are volatile, so equity SIPs suit long horizons (ideally 10+ years) and the realised value will differ.
Does this account for fees and tax?
No — it's a gross estimate. It ignores the fund's expense ratio (which reduces returns), any exit load for early redemption, and capital gains tax (equity funds: LTCG above a threshold, STCG if sold within a year; debt funds taxed differently). Your net corpus is somewhat lower than the projection.
What is a step-up SIP?
A SIP where you increase the monthly amount periodically (e.g. each year, in line with your income growth). Because the extra contributions compound, a step-up SIP builds a substantially larger corpus than a flat SIP over a long period — a powerful way to grow investing as your earnings rise. This calculator models a flat monthly amount.
