A project costs €40 000 today and returns €13 000, €13 000, €15 500, €7 000, €6 500, €12 500 at the end of years 1 to 6. Assume cash flows arrive evenly through each year. Find the payback period PB in years.
NPV & IRR worksheet with answers
A machine is expected to save €25 000, €5 000, €20 000, €8 000 at the end of years 1 to 4, after which it is worthless. The required return is 6%. What is the most the company should pay for the machine today? Find PV.
A project costs €500 000 today. It generates €44 000 at the end of the first year, and the cash flow then grows by 4% per year forever. The cost of capital is 12%. Find the net present value NPV.
An investment of €45 000 gives these cash flows at the end of years 1 to 4: €21 000, €19 000, €21 000, €22 000. The cost of capital is 5%. Find the net present value NPV.
A project costs €50 000 today. Its cash flow is €7 500 at the end of year 1 and grows by 5% per year until the last cash flow at the end of year 6. The cost of capital is 10%. Find the net present value NPV.
Project A costs €30 000 and returns €17 000, €12 000, €7 000 at the end of years 1 to 3. Project B costs €40 000 and returns €11 000, €16 000, €21 500. Find the crossover rate r* at which both projects have the same NPV, in percent.
