About the Lumpsum vs SIP Calculator

Investors with a large sum - a bonus, inheritance, or maturity proceeds - often wonder: invest it all at once or spread it monthly as SIP? In a steadily rising market, lumpsum wins because your entire capital compounds from day one. In volatile or falling markets, SIP wins by buying more units at lower prices. For most investors, market timing is nearly impossible, making SIP a safer bet for peace of mind even if not always for maximum returns.

Lumpsum vs SIP Future Value

Lumpsum FV = P × (1 + r)^n · SIP FV = P × ((1+r)^n - 1) / r × (1+r)

For fair comparison: same total investment amount · Lumpsum FV = entire amount at start, compounding for full period · SIP: divide total amount by months, invest monthly · r = monthly return, n = total months

Worked Example

₹6L to invest over 5 years: lumpsum vs ₹10,000/month SIP at 12% return

Total investment:₹6,00,000
Lumpsum return:₹6L × (1.01)^60 = ₹10.87L
SIP return:₹10,000/month × 60 months at 12%

Lumpsum (assuming 12% steady return): ≈ ₹10.87L · SIP ≈ ₹8.17L · But in a volatile market, SIP reduces regret risk significantly

Tips & Insights

  • 1

    Use STP (Systematic Transfer Plan) as a middle path: put lumpsum in a liquid fund, auto-transfer monthly to equity.

  • 2

    If markets are near all-time highs, spreading via SIP over 6-12 months reduces the risk of buying at the peak.

  • 3

    For amounts under ₹1L, lumpsum is often simpler and the SIP advantage is minimal over short periods.

  • 4

    During market corrections, lumpsum investing is typically superior - low NAVs maximize the future upside.

  • 5

    Behavioral finance shows most investors pull out lumpsum investments during crashes but maintain SIPs - SIP builds better investing habits.

Why this matters for you

There is no universally correct answer between lumpsum and SIP - the better choice depends on market conditions you cannot predict. What this calculator shows is the expected value difference, helping you make an informed choice. For most Indian investors without market timing skills, SIP or STP is the default choice that protects against the worst outcomes.
