What return should I assume for a lumpsum mutual-fund investment?

12% for equity (NIFTY 50 historical CAGR), 10% for hybrid/balanced, 7% for debt funds, 6.5% for liquid funds. Use realistic numbers — the calculator highlights how a 1% delta changes a 20-year corpus.

Lumpsum vs SIP — which gives better returns?

Lumpsum wins when the market trends up steadily after entry. SIP wins when the market is volatile or in a sustained downtrend. Over 15+ years, the two converge — both beat FD by a wide margin for equity funds.

How is the lumpsum corpus calculated?

Compound-interest formula: FV = P × (1 + r)^n, where P is the initial investment, r is the annual return, and n is years. The calculator uses annual compounding (standard for mutual funds).

Are lumpsum gains taxable?

Yes. Equity mutual funds: 12.5% LTCG above Rs 1.25L (held >12 months); 20% STCG (≤12 months). Debt mutual funds: slab rate on all gains (post-2024 indexation removed). Use the tax estimate to compare with FD/PPF on a post-tax basis.

What is the risk of a single-date lumpsum entry?

Timing risk — entering at a market peak can take years to break even. Mitigation: split a lumpsum into 6–12 monthly STPs (Systematic Transfer Plans) from a liquid fund into the target fund to smooth entry.

Should I prefer direct or regular plans for lumpsum?

Direct plans often have a 0.5%–1% lower expense ratio, which can compound to a larger corpus over 20+ years under the same assumptions. Compare the plan structure and review any applicable advisory or distribution terms before choosing.

What makes this calculator different

Equity / hybrid / debt return presets are based on long-term Indian benchmarks (NIFTY 50 CAGR for equity, BSE liquid for debt); we also surface the post-tax corpus assuming the current 12.5% LTCG regime so you see the take-home number, not the gross corpus.
