What makes this calculator different

Uses annual compounding on a one-time investment (FV = P × (1 + r)^n) and shows invested amount vs estimated gains. Returns are an assumption you set; the figure is pre-tax.

Common Questions

Lumpsum Investment Calculator FAQs

Common questions about the Lumpsum Investment Calculator and how to read its results.

Q01

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 — try a 1% lower return to see how much it changes a 20-year corpus.

Q02

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.

Q03

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).

Q04

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). The calculator shows pre-tax values, so adjust for tax when comparing with FD/PPF.

Q05

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.

Q06

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.
