Example Calculation

Inputs
  • Initial Investment: 100000 PKR
  • Monthly Contribution: 5000 PKR
  • Expected Annual Return: 12 %
  • Investment Period: 10 years
  • Annual Inflation Rate: 6 %

Suppose you enter: Initial Investment = 100000, Monthly Contribution = 5000, Expected Annual Return = 12, Investment Period = 10, Annual Inflation Rate = 6. The calculator applies the formula (FV = P(1+r)^n + PMT × ((1+r)^n − 1)/r; Real rate = (1+nominal)/(1+inflation) − 1) and shows all output values below. Change any input field to immediately see how the result changes.
