Question

Compute the payback period for each of these two separate investments:

Answer 1

Answer:

1.89 years and 2.91 years

Explanation:

The formula to compute the payback period is shown below:

= Initial investment ÷ Net cash flow

For first case

The initial investment is $260,000

And, the net cash flow is shown below:

= Depreciation + incremental after tax income

where,

Depreciation equals to

= (Original cost - residual value) ÷ (useful life)

= ($260,000 - $10,000) ÷ (4 years)

= ($20,000) ÷ (4 years)  

= $62,500

And the incremental after tax income is $75,000

So, the net cash flow would equal to

= $62,500 + $75,000

= $137,500

So, the payback period would be

= $260,000 ÷ $137,500

= 1.89 years

For second case

The initial investment is $170,000

And, the net cash flow is shown below:

= Depreciation + incremental after tax income

where,

Depreciation equals to

= (Original cost - residual value) ÷ (useful life)

= ($170,000 - $14,000) ÷ (9 years)

= ($156,000) ÷ (9 years)  

= $17,333

And the incremental after tax income is $41,000

So, the net cash flow would equal to

= $17,333 + $41,000

= $58,333

So, the payback period would be

= $170,000 ÷ $58,333

= 2.91 years
