To use this calculator, input your initial investment, the discount rate, and the expected annual cash flows for each year. The calculator will compute the profitability index, net present value, and expected cash flows.
The formula for the Profitability Index (PI) is: PI = (Present Value of Future Cash Flows) / Initial Investment. The present value of future cash flows is calculated as: CF1 / (1 + r)^1 + CF2 / (1 + r)^2 + ... + CFn / (1 + r)^n, where CF is the cash flow for each year, r is the discount rate, and n is the number of years.
Suppose you have an initial investment of $10,000, a discount rate of 10%, and expect cash flows of $1,000, $2,000, and $3,000 over the next three years. The calculator will determine the profitability index and net present value of this investment.
While the Profitability Index is a useful tool, it should not be the sole factor in investment decisions. Consider other metrics and qualitative factors. For more detailed analysis, you might also want to check our ROI Calculator and Investment Calculator.
