lump sum and sip both build wealth. but they work differently. time changes the outcome. the market phase changes the outcome.
one is not always better. each has its moment. the choice depends on when the money is available. and when the market is entered.
the core difference
sip invests a fixed amount regularly. monthly is the most common. the money enters the market in small pieces. over time.
lump sum invests the full amount on day one. the entire capital starts working immediately.
sip buys more units when markets are low. fewer when markets are high. this is rupee-cost averaging. lump sum does not have this benefit.
lump sum benefits from compounding on a larger base from the start. sip benefits from consistency and discipline.
