Drip irrigation vs flood irrigation
SIP is like drip irrigation — steady, consistent drops that nourish your investment over time. Lumpsum is like flood irrigation — one big pour that works great when the timing is right.
SIP vs Lumpsum
Two ways to invest in mutual funds: SIP (Systematic Investment Plan) for regular monthly investing, and Lumpsum for one-time investments.
SIP (Systematic Investment Plan)
SIP auto-debits a fixed amount from your bank every month (or week/quarter).
- Rupee cost averaging — buy more units when markets are low, fewer when high
- No timing needed — removes the "is now a good time?" anxiety
- Disciplined habit — automates your investing
- Start small — ₹500/month is enough
How Rupee Cost Averaging Works
Investing ₹5,000/month: Jan (NAV ₹50) → 100 units. Feb (NAV ₹40) → 125 units. Mar (NAV ₹45) → 111 units. Your average cost: ₹43.48 — lower than the simple average NAV of ₹45, because you bought more units when prices were low.
Lumpsum
Investing a large amount at once. Makes sense when:
- You received a bonus, inheritance, or windfall
- Markets have crashed significantly (but this requires conviction)
- You're investing in a debt fund for a fixed period
- Short-term parking of emergency funds
SIP vs Lumpsum
SIP Advantages
- + No market timing needed
- + Rupee cost averaging
- + Builds discipline
- + Works on any salary
Lumpsum Advantages
- - Beats SIP ~65% of the time historically
- - Deploys money immediately
- - Best for windfalls/bonuses
- - Simpler for one-time amounts
Key Takeaway
Most people should SIP their monthly savings AND lumpsum any windfalls. Don't overthink the choice — the important thing is to start investing.
