Lumpsum Calculator — Calculations & Slabs for FY 2026-27

A lumpsum investment is a one-time allocation of money in a mutual fund scheme. Instead of regular monthly intervals, the entire amount is invested upfront in one transaction, purchasing fund units at the prevailing Net Asset Value (NAV).

A lumpsum investment yields the highest returns when made during market corrections or bear phases when stock valuations are low. This allows you to accumulate more mutual fund units at lower NAVs, maximizing long-term gains.

Lumpsum investments are optimal when you have a large cash surplus (e.g. inheritance or bonus) and are willing to take on higher entry-timing risk. SIPs are generally safer for regular monthly savings as they protect you from short-term market peaks.

Gains on equity mutual funds are taxed based on tenure. If sold within 1 year, Short-Term Capital Gains (STCG) are taxed at 20%. If sold after 1 year, Long-Term Capital Gains (LTCG) are taxed at 12.5% on gains exceeding ₹1.25 lakh per financial year.
