✓ Returns calculated using standard SIP future value formula with monthly compounding · LTCG tax rate reflects Budget 2024 provision (12.5% on equity gains above ₹1.25L/year) · Historical return data sourced from AMFI India and Value Research India
Most people start a SIP with a vague sense that "equity mutual funds give around 12% returns" and a hope that the corpus will be "good" after 10 years. Very few actually sit down and calculate the exact rupee figure their specific SIP amount will produce at each return scenario — or how much of that figure will survive after LTCG tax, or what monthly SIP they need to reach a specific goal.
This article gives you all of that in one place. Exact corpus tables for ₹5,000 to ₹20,000 monthly SIPs across 10%, 12%, and 14% annual return scenarios. A year-by-year growth breakdown showing exactly when compounding starts to dominate. The LTCG tax calculation on a ₹10,000/month SIP at maturity. And the reverse calculation most goal-planners need: what monthly SIP gets you to ₹1 crore in 10, 15, or 20 years.
Every number in this article is calculated precisely using the standard SIP future value formula used by all major fund houses and financial calculators in India.
The SIP Formula — How These Numbers Are Calculated
The corpus from a regular SIP (same amount invested every month) is calculated as:
Corpus = Monthly SIP × [(1 + r)^n − 1] ÷ r × (1 + r)
Where r = annual return rate ÷ 12 ÷ 100 (monthly rate), and n = number of months. The (1 + r) at the end accounts for the fact that the first investment starts earning from the beginning of the first month — not the end.
For a ₹10,000/month SIP at 12% annual return for 10 years (120 months): r = 12 ÷ 12 ÷ 100 = 0.01 (1% per month), n = 120 months. Corpus = 10,000 × [(1.01)^120 − 1] ÷ 0.01 × 1.01 = ₹23,23,391.
The key insight buried in this formula: your money is not growing at 12% on ₹10,000 invested. It is growing at 12% on a different balance every month — the first ₹10,000 compounds for 120 months, the second for 119 months, the third for 118, all the way down to the last ₹10,000 which compounds for just one month. The average holding period is roughly 60 months — 5 years. That is why a 10-year SIP does not grow as dramatically as a 10-year lump sum investment of the same total amount.
SIP Returns Table — ₹10,000/Month for 10 Years
| Annual Return | Total Invested | Final Corpus | Total Gains | Return Multiple |
|---|---|---|---|---|
| 8% (low) | ₹12,00,000 | ₹18,41,657 | ₹6,41,657 | 1.53x |
| 10% (moderate) | ₹12,00,000 | ₹20,65,520 | ₹8,65,520 | 1.72x |
| 12% (moderate) | ₹12,00,000 | ₹23,23,391 | ₹11,23,391 | 1.94x |
| 14% (optimistic) | ₹12,00,000 | ₹26,20,914 | ₹14,20,914 | 2.18x |
| 15% (optimistic) | ₹12,00,000 | ₹27,86,573 | ₹15,86,573 | 2.32x |
Return assumptions: 8% is realistic for a conservative hybrid or large-cap index fund over 10 years. 10% is a moderate assumption for diversified equity funds. 12% aligns with the long-run historical CAGR of the Nifty 50 Total Returns Index across most rolling 10-year periods since 2000. 14–15% represents optimistic performance more typical of mid-cap or small-cap fund exposures over favourable periods. Actual returns vary yearly and across fund categories — past performance does not guarantee future results.
SIP Returns Table — Multiple Amounts for 10 Years
| Monthly SIP | Total Invested | @10% corpus | @12% corpus | @14% corpus |
|---|---|---|---|---|
| ₹5,000 | ₹6,00,000 | ₹10,32,760 | ₹11,61,695 | ₹13,10,457 |
| ₹10,000 | ₹12,00,000 | ₹20,65,520 | ₹23,23,391 | ₹26,20,914 |
| ₹15,000 | ₹18,00,000 | ₹30,98,280 | ₹34,85,086 | ₹39,31,371 |
| ₹20,000 | ₹24,00,000 | ₹41,31,040 | ₹46,46,782 | ₹52,41,828 |
Corpus scales exactly linearly with the monthly SIP amount — ₹20K/month gives exactly double the corpus of ₹10K/month at the same rate and duration.
Year-by-Year Growth — ₹10,000/Month at 12% Return
This is where the power of long-term SIP compounding becomes visible. In years 1–3, most of what you have is what you put in. By year 7, gains are starting to match contributions. By year 10, gains have nearly equalled the entire invested principal.
| Year | Invested (cumulative) | Corpus Value | Gains | Gains as % of corpus |
|---|---|---|---|---|
| 1 | ₹1,20,000 | ₹1,28,093 | ₹8,093 | 6.3% |
| 2 | ₹2,40,000 | ₹2,72,432 | ₹32,432 | 11.9% |
| 3 | ₹3,60,000 | ₹4,35,076 | ₹75,076 | 17.3% |
| 4 | ₹4,80,000 | ₹6,18,348 | ₹1,38,348 | 22.4% |
| 5 | ₹6,00,000 | ₹8,24,864 | ₹2,24,864 | 27.3% |
| 6 | ₹7,20,000 | ₹10,57,570 | ₹3,37,570 | 31.9% |
| 7 | ₹8,40,000 | ₹13,19,790 | ₹4,79,790 | 36.4% |
| 8 | ₹9,60,000 | ₹16,15,266 | ₹6,55,266 | 40.6% |
| 9 | ₹10,80,000 | ₹19,48,215 | ₹8,68,215 | 44.6% |
| 10 | ₹12,00,000 | ₹23,23,391 | ₹11,23,391 | 48.4% |
The compounding inflection point: by Year 5, gains of ₹2,24,864 are already generating more return each month than a single new SIP instalment of ₹10,000 contributes. By Year 10, the accumulated corpus is growing at ₹23,23,391 × 1% = ₹23,234 per month from compounding alone — more than double the ₹10,000 monthly SIP. This is the flywheel effect of compounding: the corpus starts doing more work than you are.
What Happens After 10 Years — The Duration Multiplier
The most powerful argument for not stopping or redeeming at 10 years is how dramatically the corpus accelerates in years 11-20. The mathematics of compounding means the second decade adds far more wealth than the first.
| Duration | Total Invested | Corpus @12% | Gains | Multiple |
|---|---|---|---|---|
| 5 years | ₹6,00,000 | ₹8,24,864 | ₹2,24,864 | 1.37x |
| 7 years | ₹8,40,000 | ₹13,19,790 | ₹4,79,790 | 1.57x |
| 10 years | ₹12,00,000 | ₹23,23,391 | ₹11,23,391 | 1.94x |
| 15 years | ₹18,00,000 | ₹50,45,760 | ₹32,45,760 | 2.80x |
| 20 years | ₹24,00,000 | ₹99,91,479 | ₹75,91,479 | 4.16x |
| 25 years | ₹30,00,000 | ₹1,89,76,351 | ₹1,59,76,351 | 6.33x |
| 30 years | ₹36,00,000 | ₹3,52,99,138 | ₹3,16,99,138 | 9.81x |
Between year 10 (₹23.23L) and year 20 (₹99.91L), your corpus more than quadruples — on just double the invested amount. The second decade produces ₹76.68L in corpus growth on ₹12L additional investment. The compounding acceleration is mathematically unavoidable for those who stay invested.
SIP vs Lump Sum — When Each Wins
A ₹12 lakh lump sum invested at 12% for 10 years grows to ₹37,27,018 — versus ₹23,23,391 for a ₹10,000/month SIP investing the same ₹12L over the same 10 years. The lump sum wins by ₹14,03,627. This is expected: a lump sum puts all money to work from day one, whereas a SIP's first rupee earns 10 years of compounding but the last rupee earns only one month.
So why does anyone use SIP?
Three reasons SIP is better for most investors
One — Availability. Most working professionals do not have ₹12 lakh available upfront. They have ₹10,000 available every month. SIP makes investing possible from month one with whatever is available.
Two — Timing risk. Investing ₹12L as a lump sum in February 2020 — two weeks before the COVID crash — would have seen an immediate 35% drawdown. The same corpus invested as a monthly SIP through 2020 bought units at progressively lower NAVs during the crash, benefiting from rupee-cost averaging. SIP eliminates the risk of catastrophic timing.
Three — Behavioural discipline. A monthly SIP auto-debit enforces investment discipline. Lump sum investing requires actively choosing to invest — which most people delay when markets are uncertain. The SIP investor invests regardless of headlines.
The honest answer: if you have a lump sum available and markets are not at a peak valuation, a lump sum will mathematically outperform SIP over most 10-year periods. If you are investing from monthly income, SIP is the correct instrument.
LTCG Tax — What You Actually Take Home After 10 Years
A ₹10,000/month SIP in an equity mutual fund for 10 years at 12% produces a gross corpus of ₹23,23,391. But equity mutual fund gains are subject to Long-Term Capital Gains (LTCG) tax — and most SIP investors do not factor this into their planning.
LTCG tax calculation on ₹10K/month, 10-year SIP at 12%
Gross corpus at redemption: ₹23,23,391
Total amount invested: ₹12,00,000
Total gains: ₹11,23,391
LTCG exemption (₹1,25,000/year): ₹1,25,000
Taxable LTCG: ₹9,98,391
LTCG tax at 12.5%: ₹1,24,799
Net corpus after LTCG tax: ₹21,98,592
LTCG on equity mutual funds (held over 12 months) is taxed at 12.5% on gains above ₹1,25,000 per financial year — this Budget 2024 rate (effective FY 2024-25 and continuing for FY 2026-27) replaced the earlier 10% rate that applied to gains above ₹1L/year.
How to reduce LTCG tax on SIP redemption
Strategy 1 — Stagger redemption across two financial years. Redeem half your corpus in March 2036 and the other half in April 2036 — using the ₹1,25,000 LTCG exemption in both FY 2035-36 and FY 2036-37. This saves ₹1,25,000 × 12.5% × 2 = ₹31,250 in additional tax compared to redeeming everything in one financial year.
Strategy 2 — Systematic Withdrawal Plan (SWP). Rather than redeeming the full corpus, set up a monthly SWP from the fund. Each withdrawal triggers LTCG only on the gains portion of that month's withdrawal, keeping annual gains below the ₹1.25L exemption if withdrawals are modest. SWP is highly tax-efficient for retirement income.
Strategy 3 — Consider ELSS for the 80C benefit. If you are filing under the Old Tax Regime, ELSS SIPs qualify for Section 80C deduction — effectively giving you a 30% tax subsidy on contributions (up to ₹1.5L/year). This partially offsets the LTCG tax at redemption.
How Much SIP Do You Need for ₹1 Crore?
The reverse calculation most financial goal-setters need: given a target corpus of ₹1 crore, what monthly SIP is required at different return assumptions and timelines?
| Timeline | At 10% annual return | At 12% annual return | At 14% annual return |
|---|---|---|---|
| 10 years | ₹48,393/month | ₹43,041/month | ₹38,137/month |
| 15 years | ₹22,973/month | ₹19,819/month | ₹17,096/month |
| 20 years | ₹13,168/month | ₹10,009/month | ₹7,646/month |
| 25 years | ₹8,103/month | ₹5,275/month | ₹3,459/month |
The time-cost of delay is enormous. Starting a ₹1 crore SIP goal at 12% return: at age 25 (25-year horizon): ₹5,275/month; at age 30 (20-year horizon): ₹10,009/month; at age 35 (15-year horizon): ₹19,819/month; at age 40 (10-year horizon): ₹43,041/month. Waiting 5 years from age 25 to 30 doubles the required monthly SIP — from ₹5,275 to ₹10,009. Waiting until 40 requires a SIP eight times larger than starting at 25.
5 Things That Determine Your Actual SIP Returns
1. The fund category matters more than the specific fund
Large-cap equity funds have historically delivered 10–12% CAGR over rolling 10-year periods. Mid-cap funds have delivered 13–16% but with higher volatility and deeper drawdowns. Small-cap funds have delivered 15–18% for extended favourable periods but can underperform for 3–5 consecutive years during market contractions. Debt funds return 6–8% with far lower volatility. The return assumption you use in this calculator should match your fund's category, not the category's best historical performer.
2. Consistency of investment matters more than timing
Multiple studies on Indian mutual fund SIP data confirm: investors who pause, reduce, or stop SIPs during market corrections — even temporarily — end up with materially lower returns than those who invest consistently. The months of a market downturn are precisely when a SIP buys the most units at the lowest NAV, setting up the largest gains when markets recover. Every pause sacrifices those low-NAV units.
3. The impact of expense ratio compounds over 10 years
A direct plan ELSS fund with a 0.5% expense ratio versus a regular plan with a 1.5% ratio appears to differ by just 1% per year. On a ₹10,000/month SIP for 10 years: the direct plan at 12% return produces ₹23,23,391, while the regular plan (effectively earning 11% after the higher expense ratio) produces ₹22,03,886 — a difference of ₹1,19,505. The expense ratio difference of 1% per year costs ₹1,19,505 in corpus over 10 years. Always choose direct plans for all equity mutual fund SIPs.
4. Exit loads affect returns if you redeem early
Most equity funds charge an exit load of 1% if units are redeemed within 1 year of purchase (some charge for up to 18 months). For a SIP investor who redeems the full corpus after exactly 10 years, the last 12 months of SIP instalments — ₹1,20,000 worth of units — may still be subject to exit load if the specific fund's exit load window hasn't expired. Check the exit load schedule before redeeming, or stagger the final year's redemption to avoid the charge.
5. Benchmark your fund — replace consistent underperformers
A SIP is not set-and-forget for 10 years with zero review. Check your fund's performance against its category average and benchmark index every year. A fund that underperforms its category average by 2% per year for 3 consecutive years should be reviewed seriously. Over 10 years, a 2% annual underperformance on a ₹10K/month SIP is the difference between ₹20,65,520 (10% return) and ₹23,23,391 (12% return) — ₹2,57,871 in corpus.

Frequently Asked Questions
How much will ₹10,000 SIP give after 10 years?
A ₹10,000/month SIP for 10 years produces the following corpus depending on annual return rate: ₹18,41,657 at 8%, ₹20,65,520 at 10%, ₹23,23,391 at 12%, and ₹26,20,914 at 14%. At the most commonly used benchmark of 12% (approximating the long-run Nifty 50 TRI CAGR across most historical 10-year rolling periods), total invested is ₹12,00,000 and total gains are ₹11,23,391 — nearly matching the entire invested principal. After LTCG tax of ₹1,24,799 (12.5% on gains above ₹1.25L), net corpus in hand is ₹21,98,592. These are projections based on constant annual returns — actual equity mutual fund returns fluctuate significantly year to year, and past performance is not a guarantee of future results.
What is a realistic return expectation for a 10-year SIP in India?
Over rolling 10-year periods since 2000, diversified large-cap equity mutual funds in India have delivered CAGRs ranging from approximately 9% (periods starting at pre-2008 highs) to 15% (periods starting at post-correction lows). The Nifty 50 Total Returns Index — the benchmark most large-cap funds aim to match or beat — has delivered a CAGR of approximately 12–13% since its inception. Mid-cap indices have delivered 13–16% over similar periods. For planning purposes, most certified financial planners use 10% as a conservative assumption and 12% as a moderate assumption for diversified equity SIPs. Projecting 15% or above over 10 years is optimistic and should be reserved for portfolios with significant mid-cap and small-cap exposure. For hybrid funds, 8–10% is more realistic.
How much monthly SIP do I need for ₹1 crore in 10 years?
To reach exactly ₹1,00,00,000 in 10 years, the required monthly SIP depends on your return assumption: ₹48,393/month at 10%, ₹43,041/month at 12%, and ₹38,137/month at 14%. For most salaried professionals, a ₹1 crore target in 10 years requires a very large monthly commitment — which is why extending the horizon significantly reduces the required SIP. The same ₹1 crore target needs only ₹19,819/month at 12% over 15 years, and ₹10,009/month over 20 years. If your income allows ₹15,000/month today, a 15-year SIP at 12% produces ₹50,45,760 — and starting a step-up SIP with 10% annual increases from the same ₹15,000 base would produce ₹76,00,000+ over the same period.
Do I pay tax on SIP gains after 10 years?
Yes — for equity mutual fund SIPs, gains are subject to Long-Term Capital Gains (LTCG) tax at 12.5% on gains above ₹1,25,000 per financial year. This rate has applied since FY 2024-25 (Budget 2024) and continues for FY 2026-27. On a ₹10,000/month SIP at 12% for 10 years: gross corpus is ₹23,23,391, gains are ₹11,23,391, taxable LTCG after ₹1.25L exemption is ₹9,98,391, and LTCG tax is ₹1,24,799 — reducing net corpus to ₹21,98,592. To reduce this tax, stagger redemption across two financial years (March and April) to use the ₹1.25L annual exemption twice, saving ₹15,625 in tax. Debt fund SIPs are taxed differently — gains are added to income and taxed at your slab rate.
Is SIP better than a fixed deposit for 10 years?
An FD at 7% for 10 years on the same cumulative investment of ₹12L (invested as a single ₹12L lump sum) grows to ₹23,60,440 — similar to a 12% equity SIP corpus of ₹23,23,391 in headline terms, but with two critical differences. First, the FD corpus is principal plus guaranteed interest — no risk of getting less. The equity SIP corpus at 12% is a projection that could be significantly lower in adverse market conditions. Second, FD interest is fully taxable at your income slab rate every year — at 30% slab, the effective post-tax FD return over 10 years is closer to 4.5–5%. The equity SIP's 12.5% LTCG tax at redemption is far lighter than annual FD interest taxation for anyone in the 20% or 30% bracket. For long investment horizons (10+ years) and investors comfortable with equity volatility, equity SIPs have historically outperformed FDs after tax by a wide margin — but this is not guaranteed.
