Start with whatever you can commit to without strain — even ₹500/month builds the habit. The step-up SIP approach is more powerful than starting with a large fixed amount: if you begin with ₹3,000/month and increase by 10% annually, after 20 years at 12% return you accumulate approximately ₹52 lakhs — nearly matching what a flat ₹5,000/month SIP would produce, despite starting much smaller. Most financial planners suggest keeping SIP at 20–30% of monthly take-home pay for a balanced approach between current lifestyle and wealth building.

It depends on the fund category and time horizon. Nifty 50 index funds have delivered approximately 12–13% CAGR over 15+ year periods. Actively managed large-cap funds typically deliver 11–15% (roughly matching or slightly beating the index). Mid-cap index funds have historically returned 15–18% CAGR but with much larger drawdowns (40–50% falls during bear markets). Use 10% as your floor scenario when planning any financial goal — this ensures the goal remains achievable even in a prolonged market slowdown like 2010–2013 when Nifty was nearly flat for 3 years.

SIP invests fixed amounts monthly, benefiting from rupee cost averaging — buying more units when prices are low and fewer when high. Lumpsum invests everything at once, giving you 100% market exposure immediately. SIP is better when you have regular income but not a large corpus upfront. Lumpsum can outperform during sustained market uptrends but carries higher timing risk.

Each month's investment earns returns that are reinvested, which then earn returns of their own. The corpus grows exponentially over time. In the early years, most of the growth comes from new investments; in later years, the growth comes increasingly from returns on the existing corpus. By year 20 at 12% return, roughly 73% of your total corpus is investment gains — not money you put in.

No — and this is the most common and costly mistake SIP investors make. Market corrections are exactly when SIP works best: your monthly amount buys more units at lower prices, dramatically lowering your average cost. Investors who stopped SIPs during the 2020 COVID crash missed buying units at 40% discount before the subsequent 100%+ rally. Stay invested.

For equity mutual fund SIPs, each monthly installment is a separate investment with its own purchase date. Units held for more than 12 months attract 12.5% LTCG (Long-Term Capital Gains) tax on gains above ₹1.25 lakh. Units held for less than 12 months attract 20% STCG (Short-Term Capital Gains). For debt fund SIPs, gains are added to income and taxed at your slab rate regardless of holding period.
