About this tool
A lumpsum investment is the opposite of SIP — you deploy a single large amount today (say from an inheritance, bonus, or sale proceeds) and let it compound for years. Mathematically the same as compound interest, but often searched as 'lumpsum calculator' in the mutual-fund context. Use this to model 'if I put ₹5 lakh in an equity fund today and leave it for 15 years, what does it become?'
Formula & notes
Future Value = Principal × (1 + r)^n, where r is the annualized return and n is number of years. If ₹5 lakh grows at 12% for 15 years, it becomes ₹27.35 lakh — a 5.5× multiple. Longer horizons compound more dramatically: same ₹5 lakh at 12% for 25 years = ₹85 lakh (17× multiple). Also handy for comparing lumpsum vs SIP outcomes (SIP has averaging benefits but lumpsum has full-time-in-market advantage).
