Chapter 2 EQUIPMENT COSTS (See examples 2.8 & 2.9) Determine cost/hr for a D9N Caterpillar dozer with the following assumptions: Engine - 370 hp Overall cost of Money -6% (1) Useful life-5 years (n) Hours used per year - 2200 Initial Cost - $400,000 (P) Cost of tires - $42,000 (for this formula you need to subtract the cost of the tires from the initial cost) Estimated Salvage Value - $40,000 (F) or ((S) for AAl formula] NOTE: Use both the USCF and the All methods to determine the answer. Find the delta (difference) between the answers and use the average of the two . . ANSWER: $/hr STEP 1 Formulas (USCF) Ap = P i (1+1)" (1+1)"-1 Af=flaton] (1+) Ap-Ag 2200 hr/yr $/HR P(n+1)+S(n-1) Formulas (AAL) AAI= = 2n AAIP = $__/YR
AAID AAlp X (1) 2200 $ /HR <1> STEP 2 AAlf = P-F = $_/Year AAlf= AAT,x(i) = $_/HR <2> 2200 AAlp + AAlt = $ = AAl cost/HR /HR USCF cost/hr = $ Ihr AAl cost/hr = Ihr Difference USCF-AAI = $ Ihr Difference /2 = $ Thr Use lower $/hr plus add difference to get average. FINAL NUMBER - $ Ihr
