Costs of storage and protection must be spread over the total hours of equipment use. The formula for the annual depreciation charge using the assumption of straight line decline in value is D = (P' - S)/N where P' is the initial purchase price less the cost of tires, wire rope, or other parts which are subjected to the greatest rate of wear and can be easily replaced without effect upon the general mechanical condition of the machine. The criteria is supplied as a reference to H4, which simply picks up the value in column F. the COUNTA function simply counts all non-blank cells in the named range category (B5:B122) to generate a total count. Varying loading and haul road conditions. In this accelerated training, you'll learn how to use formulas to manipulate text, work with dates and times, lookup values with VLOOKUP and INDEX & MATCH, count and sum with criteria, dynamically rank values, and create dynamic ranges. 4 R or T µ s if R 2 is constant. If you are looking for a formula for calculating the machine downtime, I don't know if such formula exists. However, there are some work cycles which require such variable effort that it is more useful to construct machine rates for parts of the cycle. Hopper charging in low to medium rolling resistance. Interest can be calculated by using one of two methods. Load and carry in hard digging; travel longer distances on poor surfaces with adverse grades. Large amount of travel over rough ground. Maintenance and repair rates as a percentage of the hourly depreciation for selected equipment. The key point is to separate the costs in such a way as to make the most sense in explaining the cost of operating the men and equipment. Elevating grader use. Hi all, I'm new to Power BI. Landforming, land-leveling. The time spent repairing each of those breakdowns totals one hour. Food supplements, medicine, vaccinations, and veterinarian schedules can be obtained from local sources such as agricultural extension agents. In this example, we have a list of 100 issues in Columns B to D. Each issue has a date and priority. TABLE 3.5 Machine Rate Calculation for a Power Saw1, Description - McCulloch Pro Mac 650 Power Saw, where f = social costs of labor as decimal, = 0.86 l/hr × .95 × CL +0.86 l/hr × .05 × CO), Lube oil for bar and chain = Fuel cons/2.5 × CO, Servicing and repairs = 1.0 × depreciation, TABLE 3.6 Machine Rate Calculation for a Tractor1, GHP = gross engine horsepowerCL = cost per liter for fuelLF = load factor (.54), TABLE 3.7 Machine Rate Calculation for a Team of Oxen1, TABLE 3.8 Machine Rate Calculation for a Truck1, Servicing and repairs = 1.5 × depreciation. Get over 200 Excel shortcuts for Windows and Mac in one handy PDF. This is defined as the price that equipment can be sold for at the time of its disposal. Steady loading from very tight banks. Imagine a pump that fails three times throughout a workday. Compactor use. Enter the formula shown below. Used equipment rates vary widely throughout the world. 2. Intermittent truck loading from stockpile. Read more. TABLE 3.4. Enter the loan's original terms (principal, interest rate, number of payments, and monthly payment amount) and we'll show how much of your current payment is applied to principal and interest. The salvage cost for the animal has the same definition as for a machine rate but in the case of the animal, the salvage value is often determined by its selling value for meat. This category includes everything from simple maintenance to the periodic overhaul of engine, transmission, clutch, brakes and other major equipment components, for which wear primarily occurs on a basis proportional to use. The calculation of the animal rate is similar to the machine rate, but the types of costs differ and merit additional discussion. To find the total fixed costs for the animals, the fixed costs for the animal, cart, harness, and miscellaneous investments can be calculated separately since they usually have unequal length lives and the hourly costs added together. For the standing truck, a different machine rate is often constructed using only the fixed cost and the labor cost for this part of the cycle. Insurance calculations are handled in the same way as interest and taxes. Poor underfloor conditions: wet floor, steep slopes and numerous stumps. Fuel Consumption
