How to use Lump Sum Investment Calculator
Project an upfront investment, purchasing power and an equivalent monthly SIP.
Inputs and definitions
Initial investment, duration, assumed effective annual return, ongoing costs and inflation.
Method and formula
Future value = principal × (1 + net effective annual return)ᵗ. Purchasing power discounts that future amount using assumed inflation.
Illustrative example
₹1 lakh for two years at an assumed net 6% annual return becomes ₹1,12,360 before tax. The investment can perform differently, including losing value.
Scope and limitations
Effective annual return after ongoing costs, before tax. Negative returns and short horizons are supported.
