Answer:
It will take 3 years and 279 days to cover for the initial investment.
Step-by-step explanation:
Giving the following information:
Initial investment= $345,000
Annual cost saving:
Cf1= $220,000
Cf2 to 4= $100,000
Discount rate= 9%
The payback period is the time required to cover for the initial investment:
Year 1= (220,000/1.09) - 345,000= -143,165.14
Year 2= (100,000/1.09^2) - 143,165.14= -58,997.14
Year 3= (100,000/1.09^3) - 58,997.14= 18,221.21
To be more accurate:
(58,997.14/77,218.35)*365= 279 days
It will take 3 years and 279 days to cover for the initial investment.
