About Lumpsum Investment Calculator
The lumpsum calculation is compounding in its purest form: one decision, then time does everything. ₹5 lakh at 12% becomes ₹15.5 lakh in 10 years — a 3.1× multiple — and the year-by-year schedule shows the signature curve: the last three years add more than the first five combined, because growth applies to an ever-larger base. The famous intuition checkpoints live in this formula: at 12%, money doubles every ~6 years (rule of 72), so 10 years ≈ one double plus most of another; at 15%, three doublings fit in 15 years for an 8× multiple. Internalize the multiples and you can price any 'investment opportunity' pitch in your head before anyone's spreadsheet loads. What the clean math hides: a constant 12% doesn't exist — real equity decades deliver their average through +30% and −20% years, and the sequence doesn't matter for a true buy-and-hold lumpsum (ending value depends only on the compound average), but it matters enormously for your nerve. The investor who holds through the −20% year earns the table above; the one who exits earns a different, smaller table.

Frequently asked questions
₹5 lakh 10 saal me kitna ho jayega?+
Return par: 8% (debt-heavy) par ~₹10.8 lakh, 10% par ~₹13 lakh, 12% (equity long-run) par ~₹15.5 lakh, 15% par ~₹20.2 lakh. Asli sawaal return assumption ka hai — horizon 10 saal ka ho to equity-oriented 11–12% defensible planning number hai, guarantee nahi.
Lumpsum kab sahi hai aur SIP kab?+
Paisa ek saath PAS HAI (bonus, sale proceeds, maturity) to lumpsum/STP ka sawaal hai — expected value me lumpsum aage, regret-protection me 6–12 mahine ka STP. Paisa har mahine AATA hai to SIP hi ekmatra rasta hai. Dono ka math hamare sip-vs-lumpsum tool me side-by-side hai.
Power of compounding ko maximize kaise karein?+
Teen hi lever hain: principal (jitna jaldi jitna zyada), rate (asset allocation — risk ke saath), aur TIME (sabse sasta lever). Inme se time akela aisa hai jo bina extra paisa ya extra risk ke multiple badhata hai: 12% par 10 → 20 saal karne se 3.1× seedha 9.6× ho jata hai. Jaldi shuru karna hi strategy hai.
Is the gain here taxable?+
On redemption, per asset class: Indian equity funds — LTCG above the annual exemption at the prevailing rate after 12 months; debt funds — at slab; stocks similar to equity funds. The calculator shows pre-tax growth; long holding periods don't just compound returns, they defer (and often reduce) the tax drag too.
