How lumpsum returns are estimated

A lumpsum investment means you put a single amount into a mutual fund (or similar) at once, instead of paying every month like a SIP. Returns are not guaranteed—we apply a fixed annual rate with monthly compounding to show what steady growth could look like.

Maturity = P × (1 + r)n, where P is your lumpsum, r is the monthly rate (annual ÷ 12 ÷ 100), and n is the number of months.

Planning monthly installments instead? Use the SIP calculator. For regular withdrawals from a corpus, try the SWP calculator. Read SIP vs lumpsum when you are unsure which fits your situation.

How to use this calculator

  1. Enter your one-time investment in rupees (e.g. ₹1,00,000).
  2. Set expected annual return (e.g. 12 for 12%)—use a conservative rate for planning.
  3. Choose how many years you expect to stay invested.
  4. Read maturity value, total invested (same as lumpsum), and estimated returns.
  5. Use the year-wise table to see how value could build over time.

Worked examples

Sample numbers you can try in the calculator above. Your lender's quote may differ slightly.

  • ₹1 lakh for 10 years at 12%

    One payment upfront. Compounding works on the full balance each month.

    ₹1,00,000 lumpsum · 12% p.a. · 10 years

    Maturity: Maturity ≈ ₹3.1 lakh

  • ₹5 lakh for 15 years at 10%

    Larger starting amount and long tenure amplify compounding versus short horizons.

    ₹5,00,000 lumpsum · 10% p.a. · 15 years

    Maturity: Maturity ≈ ₹20.9 lakh

  • ₹50,000 for 5 years at 8%

    A lower assumed rate gives a safer planning figure than peak equity returns.

    ₹50,000 lumpsum · 8% p.a. · 5 years

    Maturity: Maturity ≈ ₹74,000

  • ₹10 lakh for 20 years at 11%

    Long hold periods matter for one-time investments—timing the entry day still affects real NAV.

    ₹10,00,000 lumpsum · 11% p.a. · 20 years

    Maturity: Maturity ≈ ₹81 lakh

Frequently asked questions about the lumpsum calculator

  • What is a lumpsum investment in mutual funds?

    Lumpsum means investing a single amount at once. Units are bought at that day's NAV. It is the opposite of SIP, where you invest the same amount every month.

  • How is lumpsum maturity calculated?

    We compound your initial amount monthly: balance grows at annual rate ÷ 12 each month for the full tenure. Maturity is the balance after the last month.

  • Is lumpsum better than SIP?

    Lumpsum can do well if markets rise after you invest; SIP spreads purchases and reduces timing risk. Many investors use both. Compare scenarios with our SIP calculator and the guide SIP vs lumpsum.

  • What return rate should I use?

    Use a rate you are comfortable planning with—often 10–12% for long equity horizons in India, lower for debt. Past performance does not guarantee future returns.

  • Does this include tax or exit load?

    No. It shows gross estimated value before tax, charges, or exit load. Check your fund factsheet for details.

  • Is this lumpsum calculator free?

    Yes. It runs in your browser with no signup.
