A Systematic Investment Plan (SIP) calculates compounding returns using the annuity formula: FV = P × [((1 + i)^n - 1) / i] × (1 + i), where P is the periodic monthly investment, i is the periodic interest rate (annual CAGR / 12), and n is the total number of monthly payments. Over long horizons, exponential compounding accelerates returns on reinvested capital.

A Step-Up (or Top-Up) SIP periodically increases your monthly contribution amount (e.g., 10% annually) to match career wage growth and salary hikes. Enabling a 10% step-up can more than double your terminal accumulated corpus over 15–20 years compared to a fixed, static monthly investment.

Under revised Indian tax provisions, Long Term Capital Gains (LTCG) on equity mutual funds held for over 12 months are taxed at a flat rate of 12.5% on capital gains exceeding the annual exemption limit of ₹1,25,000. Short Term Capital Gains (STCG) on equity funds held for 12 months or less are taxed at 20%. Debt fund gains are taxed at applicable individual income tax slab rates.

A 6% annual inflation rate reduces purchasing power by half approximately every 12 years (Rule of 72). For instance, an estimated ₹1 Crore nominal corpus accumulated over 20 years will possess a real present purchasing power equivalent to approximately ₹31.18 Lakhs in today's terms. Evaluating inflation-adjusted real returns is crucial for realistic goal planning.
