Quick Answer / Summary

A monthly investment of ₹25,000 in an equity SIP at an expected 12% annual return over 15 years generates an estimated maturity corpus of ₹1.26 Crore (₹1,26,14,400). You invest a total of ₹45.00 Lakh and earn ₹81.14 Lakh in compounding wealth gain.

How this SIP calculator works

How is this calculated? Full Methodology & Proof →

A Systematic Investment Plan (SIP) enables disciplined rupee-cost averaging by investing a fixed sum on a scheduled day every month into mutual fund units. Each installment earns compound interest over its remaining tenure. Because units are bought each month across market highs and lows, your average acquisition cost stabilizes over long horizons.

Calcumetrics computes SIP maturity using the standard annuity-due formula with monthly compounding. Annuity-due assumes installments are credited at the beginning of each month (matching the banking auto-debit schedule of Indian mutual fund AMCs):

FV = P × [((1 + i)ⁿ − 1) / i] × (1 + i)
FV = Future Value (estimated maturity corpus)
P = Monthly investment installment
i = Monthly interest rate = Annual Rate / 12 / 100
n = Total installments = Tenure in Years × 12

Worked mathematical example

Here is how the formula calculates a ₹25,000 monthly SIP at 12% p.a. over 15 years step-by-step:

Step 1:Monthly rate: i = 12 / (12 × 100) = 0.01
Step 2:Total monthly installments: n = 15 × 12 = 180 months
Step 3:Compound factor: (1 + 0.01)¹⁸⁰ − 1 = 5.995802 − 1 = 4.995802
Step 4:Annuity-due multiplication: 25,000 × (4.995802 / 0.01) × 1.01 = ₹1,26,14,400
Total Invested: ₹45,00,000Wealth Gain: ₹81,14,400

Key limitations & common misconceptions

Returns Are Not Linear

A 12% expected return does not mean 1% every month. Markets fluctuate with negative years followed by sharp recoveries.

Inflation Impact

This calculator outputs nominal values. A ₹1.26 Cr corpus 15 years from now has a real purchasing power of ~₹52.6 Lakh at 6% inflation.

Budget 2024 Tax Rules

Equity fund LTCG held > 12 months is taxed at 12.5% on gains exceeding ₹1.25 Lakh per financial year.

Frequently asked questions

What is a SIP calculator and how does it work?
A SIP calculator computes the estimated maturity corpus and capital gains of a Systematic Investment Plan. It applies compound interest on regular monthly contributions debited at the start of each month using the annuity-due mathematical formula.
Is a 12% return realistic for mutual fund SIPs in India?
Historically, diversified Indian equity mutual funds (large-cap, flexi-cap, and index funds tracking Nifty 50 or Sensex) have delivered 11% to 14% CAGR over rolling 10 to 15-year periods. However, equity returns are subject to market volatility and are not guaranteed.
What formula does this SIP calculator use?
This calculator uses the standard annuity-due formula: FV = P × [((1 + i)^n − 1) / i] × (1 + i), where P is the monthly investment amount, i is the monthly interest rate (annual rate / 12 / 100), and n is total months (years × 12).
SIP vs Lumpsum: which is better for wealth creation?
SIP is ideal for salaried individuals as it enforces investing discipline and leverages Rupee Cost Averaging to buy more units when markets dip. Lumpsum investing can generate higher returns when markets are undervalued, but carries higher entry timing risk.
What happens if I miss a monthly SIP installment?
If your bank account lacks sufficient balance, the fund house does not penalize or cancel your folio, though your bank may levy an auto-debit bounce charge. If three consecutive monthly debits fail, the mutual fund AMC may automatically pause the mandate.
Are mutual fund SIP returns tax-free in India?
No. Under Budget 2024 tax rules, Long-Term Capital Gains (LTCG) on equity mutual funds held for more than 12 months are taxed at 12.5% on capital gains exceeding ₹1.25 lakh per financial year. Short-Term Capital Gains (STCG) on units held up to 12 months are taxed at 20%.
What is a Step-Up SIP?
A Step-Up (or Top-Up) SIP automatically increases your monthly installment amount periodically (typically 5% to 10% each year in line with annual salary increments). This accelerates corpus accumulation significantly over long investment horizons.
