Answer: 3.47 years
Step-by-step explanation:
Payback Period on an investment can be calculated as:
= Cost of investment / Net annual cash inflow
The internal rate of return is the rate that equates the Cost of investment to the annual net cash inflow. This means that if you were to solve for the IRR factor, the formula would be:
= Cost of investment /Net annual cash inflow
Notice how the formulas are the same.
The factor for IRR is therefore the Payback period.
Using your Present value of an Annuity Factor table therefore, find the Factor for the IRR rate of 6% and 4 years.
= 3.4651
= 3.47 years
