How Much SIP to Reach ₹25 Lakh in 18 Years
An average middle-class Indian wedding costs ₹15–30 lakh today. With inflation running 6–8% in wedding-related spending, a ₹25 lakh corpus in 18 years is realistic for a child born today — enough to cover a comfortable wedding without depleting retirement savings.
Monthly SIP Required to Reach ₹25 Lakh
Exact monthly SIP you need to reach ₹25 Lakh across different durations and return rates, using the standard annuity-due SIP formula.

| 10 | ₹12,103 | ₹10,760 | ₹8,972 |

Who Should Plan for ₹25 Lakh?
This goal suits parents of young children planning for wedding expenses 15–20 years ahead. An average middle-class Indian wedding costs ₹15–30 lakh today. With inflation running 6–8% in wedding-related spending, a ₹25 lakh corpus in 18 years is realistic for a child born today — enough to cover a comfortable wedding without depleting retirement savings.
Step-up alternative: Instead of a flat ₹3,266 SIP for 18 years, you could start at roughly ₹1,960 per month and increase 10% annually. Both paths reach ₹25 Lakh, but the step-up approach is easier on your current cash flow because it scales with salary growth.
Choosing the Right Fund Category
The fund mix depends on how many years you have. For 18 years, consider:
- Equity-heavy mix (18+ years): 70–80% in diversified equity (flexi-cap, large & mid-cap, active multi-cap). 20–30% in hybrid or debt for stability.
- Pure index funds: Nifty 50 or Nifty 500 index funds have the lowest expense ratios (0.10–0.30%) and simple mental model. A solid default for beginners.
- ELSS funds: If you also want ₹1.5L tax deduction under 80C, allocate part of the SIP to ELSS funds. 3-year lock-in per installment.
What Could Derail This Goal?
The biggest risks are not market volatility — they are behavioral. Investors who pause SIP during crashes realize far lower returns because they miss the biggest wealth-building months. Similarly, raiding the corpus for non-emergencies resets the compounding clock. Automate the SIP, set a separate emergency fund, and commit to the full tenure.
Inflation is the second quiet risk. ₹25 Lakh today is not the same as ₹25 Lakh in 18 years. Build in a 20–30% buffer by aiming for ₹32.5 lakh if your goal is fixed in today's purchasing power.
Frequently Asked Questions
How much SIP is required to reach ₹25 Lakh in 18 years?
At a conservative 12% annual return, you need ₹3,266 per month. At 10%, the figure rises to ₹4,128 per month, and at 15% you need only ₹2,264 per month. The calculator on this page lets you plug in any rate and duration.
Is ₹25 Lakh in 18 years realistic?
Yes. Historical Indian equity mutual fund CAGR is 11–14% over 10–year rolling periods. A 18-year horizon lets equity volatility average out, and the required monthly SIP is achievable if you're willing to automate the investment and let compounding run.
What type of mutual fund should I choose for this SIP?
For horizons above 10 years, use diversified equity funds — flexi-cap, large & mid-cap, or an active multi-cap. For shorter horizons (under 7 years) mix equity with hybrid or debt to cushion volatility. Low expense-ratio index funds are the simplest default for beginners.
What if I can't afford the required monthly SIP?
Start with whatever you can sustain and enable a step-up SIP that increases the contribution 10% every year. A step-up schedule reaches the same goal with a much lower starting amount because your contributions scale with your salary growth.
How is the SIP amount calculated to reach ₹25 Lakh?
We back-solve the standard SIP future value formula: FV = P × [((1+r)^n – 1)/r] × (1+r). Given your target FV, the expected return r and the number of months n, we compute the required monthly contribution P.
Does this include tax on long-term capital gains?
No — the output is pre-tax. Equity mutual funds held over 1 year attract 12.5% LTCG above ₹1.25 lakh annual exemption (FY 2024–25). Plan for a 2–4% haircut on realized returns.
