NPV & IRR

Appraise a project: net present value, internal rate of return, payback and profitability index.

What you enter

  • Initial investment
  • Discount rate (cost of capital)
  • Cash flows by year

How this is calculated

  • NPV = Σ cash flow in year t ÷ (1 + discount rate)^t, with year 0 = −initial investment.
  • IRR = the discount rate at which NPV = 0.
  • Payback = years until cumulative cash flow turns positive (interpolated within the year).
