Answer:
The payback period is exactly 4 years.
Step-by-step explanation:
Giving the following information:
Initial investment= $1,090,000
Cf1= 109,000
Cf2= 218,000
Cf3= 327,000
Cf4= 436,000
Cf5= 545,000
The payback period is the time required to cover the initial investment:
Year 1= 109,000 - 1,090,000= -981,000
Year 2= 218,000 - 981,000= -763,000
Year 3= 327,000 - 763,000= 436,000
Year 4= 436,000 - 436,000= 0
The payback period is exactly 4 years.
