Lumpsum invests the entire amount upfront on Day 1. SIP spreads the same total amount over monthly installments, optionally with annual step-up. Both use the same expected return assumption so you can compare timing advantage and discipline advantage clearly.

Value, SIP deployment, and strategy lead over timeLumpsum vs SIP: What You Should Know
Lumpsum = More Time in Market
When returns are positive and money is available upfront, lumpsum usually has a mathematical edge because more capital compounds from Day 1.
SIP = Better Behavioural Discipline
SIP spreads purchases across time, reduces timing anxiety, and helps investors stay consistent even during volatile phases.
Use Both Intelligently
Many investors combine both: deploy surplus cash as lumpsum when suitable, while continuing SIPs for long-term discipline.
