Worked Example Sandbox

For illustrative purposes, consider the following calculation using our default values. When we initialize the input fields with Initial Investment (negative) = -100000 $, Year 1 Cash Flow = 25000 $, Year 2 Cash Flow = 30000 $, Year 3 Cash Flow = 35000 $, Year 4 Cash Flow = 40000 $, Year 5 Cash Flow = 45000 $, the client-side calculator processes the numbers to resolve the formula and produce the final outputs: Total Cash Flows = 75,000 $ and Est. IRR = 35 %.
