Net Present Value Method—Annuity

Briggs Excavation Company is planning an investment of $1,077,200 for a bulldozer. The bulldozer is expected to operate for 3,000 hours per year for 10 years. Customers will be charged $150 per hour for bulldozer work. The bulldozer operator costs $29 per hour in wages and benefits. The bulldozer is expected to require annual maintenance costing $30,000. The bulldozer uses fuel that is expected to cost $38 per hour of bulldozer operation.

a. Determine the equal annual net cash flows from operating the bulldozer. Use a minus sign to indicate cash outflows.

b. Determine the net present value of the investment, assuming that the desired rate of return is 15%. Use the present value of an annuity of $1 table above. Round to the nearest dollar. If required, use the minus sign to indicate a negative net present value.

C. Determine the number of operating hours such that the present value of cash flows equals the amount to be invested. Round interim calculations and final answer to the nearest whole number.

Explanation / Answer

A.

B.  

Present value of annual net cash flows = Annual net cash flow * annuity factor (15%, 10years)

= $219,000 * 5.019

= $1,099,161

C. To find out number of operating hours to equalise our investment and present value of cash flows , If we assume annual hours of operation as X in table in above point A and B, then we have following equation

(150X - 67X - 30,000) * 5.019 = $ 1,077,200

83X - 30,000 = $214,624

83X = 214,624 +30000

83X = 244,624

X = 244,624 / 83

X = 2947 hours

Therefore, if buldozer operates for 2947 hours every year then the present value of cash flows will be equal to the amount of investment.

Cash inflows: Hours of operation 3000 Revenue per hour $150 Revenue per year (A) $450,000 Cash outflows: Hours of operation 3000 Fuel cost per hour $38 Labor cost per hour $29 Total fuel and labor costs per hour $67 Fuel and labor costs per year (B) $201,000 Maintenance costs per year (C) $30,000 Annual net cash flows (A-B-C) $219,000
