3.1. Hourly Depreciation Calculation

The equivalent uniform annual cost of initial cost = Initial cost × [ ] (1+i)^n - 1 = 2,89,00,000 × [ ] (1+0.08)^{12.5} - 1 = ₹ 37,41,844.41/year. So this IC is named equivalent to A using uniform series capital recovery factor.

This chunk discusses how to convert an initial cost into an annual equivalent using a recovery factor. The formula used involves the interest rate and the number of years, which helps in understanding how much that cost would amount to each year over its lifespan. Specifically, after applying the formula, we find that the annualized initial cost, which is the amount to be accounted for each year, is ₹ 37,41,844.41.

Think of it as buying a car. If you buy a car for ₹ 20,00,000 and plan to use it for 10 years, you might want to think about how much money you should set aside every year to reflect the cost of owning that car—this is similar to calculating annualized costs.

Equivalent uniform annual cost of salvage value = Salvage value × [ ] (1+i)^n - 1 = 0.2 × 2,89,00,000 × [ ] = ₹ 2,85,968.88/year.

This chunk elaborates on how to convert the future salvage value of equipment into an annual cost. Here, 'salvage value' is an estimated value after using an asset for a certain period. By using the formula similar to that of the initial cost, we find that the annualized salvage value is ₹ 2,85,968.88. This means that at the end of its useful life, the machine’s value can contribute ₹ 2,85,968.88 per year towards recovering costs.

Imagine you expect to sell your smartphone for ₹ 20,000 after two years. When calculating how much that future sale will contribute towards your current costs, you treat it as if you're earning that amount over those two years.

Hourly Depreciation = (Annualized Initial Cost - Annualized Salvage Value) / Annual Use in Hours = (37,41,844.41 - 2,85,968.88) / 1600 = ₹ 2159.92/hr.

This chunk shows how to calculate hourly depreciation. This is the cost incurred for every hour of use of the machine. It subtracts the annualized salvage value from the annualized initial cost and divides the result by the total machine usage hours in a year (1600 hours). Doing the math gives us an hourly depreciation of ₹ 2159.92, which is a crucial figure for budgeting maintenance and operations.

If you rent a bicycle and it costs you ₹ 5000 to buy, but you can sell it for ₹ 1000 after one year, the hourly cost of using that bicycle is similar to determining how much money you need to allocate for every hour you use it, taking into account its resale value.

Hourly insurance cost = (Insurance Percentage × Initial Cost) / Annual Use = (2.0 × 2,89,00,000 / 100) / 1600 = ₹ 361.25/hr. Hourly taxes = (3.0 × 2,89,00,000 / 100) / 1600 = ₹ 541.88/hr. Total hourly ownership cost = Hourly depreciation + Hourly insurance + Hourly taxes.

This chunk discusses how to compute additional ownership costs such as insurance and taxes. The formulas used involve multiplying the respective percentages by the adjusted costs and dividing by the total annual hours of operation to get hourly rates. Including these costs in the overall cost structure is critical for comprehensively understanding the total expenditure incurred in operating the machinery.

Consider you pay an annual insurance premium and property taxes for a house. If you allocate these costs over the number of hours you use your home (or the time it's rented out), you can determine how much your home 'costs' you per hour each year.

Total hourly ownership cost = ₹ 2159.92 + ₹ 361.25 + ₹ 541.88 = ₹ 3063.05/hr.

This chunk sums up all the ownership costs calculated earlier to derive the total hourly ownership cost, which is ₹ 3063.05. This figure represents all costs associated with owning and operating the machine on an hourly basis, crucial for budgeting and cost analysis.

If you run a coffee shop, the total cost of making one cup of coffee includes the cost of ingredients, labor, and operation, and you calculate this to see how much each cup really costs you, which ultimately affects your pricing.
