SIP and lump sum are ways to put money into the same mutual fund. The difference is timing: SIP spreads purchases across months; lump sum deploys cash at once. Neither removes market risk — they manage when you buy.
What each approach optimises
SIP fits salary cash flow and reduces the chance of investing everything at a short-term peak. Lump sum puts money to work immediately, which can help if markets rise soon after — and can hurt if they fall.
If the money is still in a savings account “waiting for a dip,” you are already making a market-timing decision. A planned SIP schedule is often easier to stick with than an endless wait.
A practical decision frame
Use SIP when investing from monthly surplus. Consider lump sum (or a few tranches over weeks/months) when you already hold surplus cash earmarked for long-term equity and your emergency fund is intact.
Horizon matters: for goals within a few years, equity timing risk is larger regardless of SIP vs lump sum — prefer safer buckets for near-term needs.

Run the SIP Calculator for a monthly plan and the Goal Planner for a dated target. Stress both optimistic and conservative returns. Do not treat past “SIP beat lump sum” charts as a rule for the next decade.
