How the SIP Compounding Formula Works
Because SIP contributions occur on the first business day of each month, the future value is computed using the monthly annuity due formula:
Where:
- P = Monthly SIP installment amount
- i = Monthly expected return rate (Annual Return ÷ 12)
- n = Total number of monthly installments (Years × 12)
The Compounding Advantage of an Annual Step-Up
Most investors start an SIP with a fixed amount and leave it unchanged for a decade. However, your earnings typically increase each year through annual salary appraisals and business growth.
Enabling an Annual Step-Up of 10% increases your monthly installment once every 12 months. On a starting ₹10,000 monthly SIP over 15 years at 12% CAGR:
- Flat SIP (No Step-Up): Invests ₹18.0 Lakh total; produces approximately ₹50.45 Lakh.
- 10% Step-Up SIP: Invests ₹38.1 Lakh total; produces approximately ₹83.42 Lakh.
Stepping up your SIP by just 10% each year yields nearly ₹33 Lakh in additional wealth over the same time horizon.
Nominal Value vs Real Purchasing Power (6% Inflation)
Accumulating ₹1 Crore in 20 years sounds impressive, but what will that money actually buy? At a realistic 6% domestic inflation rate, consumer goods will cost roughly 3.2 times more in 20 years. That future ₹1 Crore will have the purchasing power of roughly ₹31 Lakh in today's terms. Our calculator provides both nominal maturity figures and real inflation-adjusted values so you can plan with realistic numbers.
Tax Treatment of Equity SIP Returns in India
- Long-Term Capital Gains (LTCG): Mutual fund units held for longer than 12 months qualify as LTCG. Gains exceeding ₹1.25 Lakh across all equity assets in a financial year are taxed at 12.5% without indexation.
- First-In, First-Out (FIFO) Rule: Each monthly SIP installment has its own 12-month holding period. When you redeem mutual fund units, the oldest units are redeemed first.
- Direct vs Regular Plans: Always invest in Direct-Growth mutual fund plans. Regular plans pay ongoing distributor commissions (0.5% to 1.0% annually), which can reduce your final 20-year portfolio wealth by ₹10 Lakh to ₹20 Lakh.
Frequently Asked Questions
What is a realistic long-term return rate for equity mutual funds in India?
Historically, broad Indian market benchmarks (such as Nifty 50 and SENSEX) have delivered 11% to 13% compound annualized growth over 10 to 15 year rolling periods. For sound long-term planning, assuming 11% to 12% before inflation provides a prudent baseline.
Should I pause my SIP when stock markets crash?
No. Market downturns are precisely when SIPs deliver their greatest benefit: your fixed monthly installment purchases more mutual fund units at lower Net Asset Values (NAVs). Stopping your SIP during a correction locks in underperformance and negates rupee-cost averaging.
What is the difference between SIP and recurring deposit (RD)?
A recurring deposit with a bank offers guaranteed fixed interest (typically 6.5% to 7.0%), but interest is taxed at your full income slab rate and fails to beat 6% inflation. An equity mutual fund SIP is market-linked, offers higher wealth generation potential (11% to 13%), and enjoys more favorable capital gains taxation.
