Each monthly instalment compounds at the assumed monthly rate for however many months remain until the end of the tenure. Summed across all 312 instalments, this is the future value of an ordinary annuity: FV = M × [((1 + i)ⁿ − 1) / i] × (1 + i), where M is the monthly investment, i is the monthly rate (annual rate ÷ 12 ÷ 100), and n is the number of months. Substituting your numbers — M ≈ ₹74,500, i ≈ 0.010000, n = 312 — and working through the formula lands on the ₹16,02,57,848 figure used throughout this page.

Total invested is simply M × n = ₹2,32,44,000; the difference between that and the final value, ₹13,70,13,848, is the estimated growth attributable to the assumed 12% return compounding on each instalment for its own remaining time in the market.

• Total invested (principal via SIP): ₹2,32,44,000 across 26 years.
• Estimated returns (growth component): ₹13,70,13,848 — about 589% of what you invested, under the stated assumption.
• Estimated final value: ₹16,02,57,848 (invested + estimated returns).

This page models a flat, unchanging monthly instalment — a regular SIP. In practice, three common variants show up on fund platforms:

A step-up SIP starting at the same ₹74,500 but rising 10% every year would out-accumulate this page’s flat-instalment estimate by the end of 26 years, simply because later years contribute a larger monthly amount — model that scenario by periodically increasing the monthly figure in the calculator above and comparing the resulting maturity values.

Sometimes the more useful question is not “what will ₹74,500/month become?” but “how much do I need to invest to reach a specific goal?” Using the same 12% assumption and 26-year horizon, reaching a round target of about ₹32,05,00,000 would need a monthly SIP of roughly ₹1,49,000 — noticeably different from the ₹74,500 used elsewhere on this page, which is exactly why goal-based planning should start from the target, not from whatever amount feels comfortable to commit today.

This kind of reverse calculation is especially useful for named goals — a child’s education corpus, a down payment, or a retirement number — where the end amount is fixed by real-world costs and the question is purely how much monthly discipline it takes to get there under a given return assumption. Run this logic in the calculator above by adjusting the monthly amount until the projected maturity matches your target.

Taxation depends on the fund category and how long each instalment has been held — every SIP instalment is treated as a separate investment for holding-period purposes, so a single SIP can straddle both short-term and long-term tax treatment at redemption. For equity-oriented funds, gains on units held over 12 months are treated as long-term (LTCG), typically taxed at a preferential rate above an annual exemption threshold, while gains on units held 12 months or less are short-term (STCG) and taxed at a higher flat rate. For debt-oriented funds, most gains — regardless of holding period — are added to your income and taxed at your slab rate under rules effective from April 2023, without the indexation benefit that debt funds used to enjoy.

Because rates, thresholds, and fund-category definitions have changed materially in recent budgets and can change again, do not assume the specific numbers here still apply at the time you redeem — confirm the current-year capital gains rules with a chartered accountant or the fund’s official statement of account before filing.

A mutual fund SIP is one of several ways Indians build long-term wealth through regular contributions. Here is how it broadly compares with a few common alternatives:

None of these is universally “better” — a well-built plan often uses more than one, matching each goal’s time horizon and your tolerance for seeing the balance dip before it recovers. EasyCal’s PPF and FD calculators use the same input-driven approach as this page if you want to model those alternatives side by side.

• Complete KYC once (Aadhaar/PAN-based e-KYC) via any registered mutual fund platform, registrar and transfer agent (RTA), or the fund house directly — this is a one-time step that then works across fund houses.
• Pick a fund category aligned to your goal and horizon — equity for long-term growth where you can tolerate drawdowns, debt or hybrid funds for shorter horizons or a lower volatility tolerance.
• Prefer a direct plan over a regular plan where you are comfortable choosing funds yourself — direct plans skip distributor commission, which compounds into a meaningfully larger corpus over long tenures purely from the lower expense ratio, with no difference in the underlying portfolio.
• Set up an e-mandate (NACH or UPI Autopay) so the instalment debits automatically on a fixed date every month — automation is what makes “regular” investing actually regular, since it removes the monthly decision to transfer money manually.
• Review the mandate once a year against your income and goals — this is a natural checkpoint to consider a step-up rather than leaving the instalment flat for a decade while your income rises.
• Keep your folio consolidated under one PAN and email ID across fund houses — it makes annual statements, tax reporting, and nominee updates far simpler than scattering investments across many logins.

Same SIP, different horizons

Holding monthly contribution and rate constant, here is how maturity changes at 5, 10, 15, and 20 years.

Same tenure, different monthly amounts

Roughly ±15–25% around ₹74,500 per month — useful for “what if I step up my SIP?” thinking.

To compare mental models, consider an illustrative fixed-income return of 7% used only as a contrast — not a quote: at the same ₹74,500 monthly for 26 years, a simplistic FD-style path would imply a maturity near ₹6,60,19,198 under that alternate assumption. Equity SIPs are not FDs; this contrast explains why people compare “SIP vs FD” even though risk profiles differ.

• Stopping the SIP the moment markets fall — volatility during the accumulation phase is exactly what allows rupee-cost averaging to buy more units at lower prices.
• Choosing a fund purely on trailing 1-year returns instead of consistency across market cycles and the fund’s mandate.
• Running many small SIPs across near-identical funds instead of a focused, well-diversified handful — more folios rarely means more diversification.
• Ignoring the expense ratio difference between direct and regular plans, which quietly compounds against you over 26 years.
• Treating the assumed 12% return as a promise rather than a planning assumption — rerun this page with a more conservative rate before committing to a large future goal.
• Redeeming the entire corpus in one go at the goal date instead of gradually de-risking into debt or a systematic transfer plan (STP) in the last 1–3 years.
• Comparing SIP returns against bank deposit rates without adjusting for risk — the two are not substitutes, and a fair comparison accounts for volatility, taxation, and liquidity, not just the headline number.
• Forgetting to update your nominee and folio details after major life events (marriage, new bank account) — a small administrative task that avoids real friction for your family later.
