Lumpsum calculator — one-time investment growth
Deploy ₹40,00,000 once at 17% a year for 18 years, and this illustration lands near ₹6,75,15,813 — about ₹6,35,15,813 in growth on top of principal. Weigh that against drip-feeding the same capacity through monthly SIPs when you think about timing risk.
A lumpsum puts every rupee to work from day one — strong when you accept today’s entry level and can stay long; harder when you prefer to average in. The math here uses one annual compounding step for clarity; it is not a scheme document.
What follows: your baseline, tenure and principal grids, return sensitivity, and a SIP contrast. Market-linked funds do not promise the assumed rate.
How this lumpsum growth model works
We apply the stated annual return once per year to the running balance — a simple compounding loop that separates principal, accumulated interest, and maturity. Real mutual funds mark to market daily; this model smooths returns into one annual step so you can compare scenarios quickly.

Comparison: lumpsum vs SIP (illustrative)
For perspective, an illustrative SIP of ₹18,519 per month at 12% for 18 years could land near ₹1,41,75,169 — different risk/return path than a one-time lumpsum; not a recommendation.
Lumpsum vs SIP is not a moral choice — it is a cash-flow and risk trade-off. If you already hold a large corpus, lumpsum deployment may be appropriate; if you are early in your career, SIPs can enforce discipline. Use both calculators on EasyCal to stress-test assumptions.
