Today we will learn how to calculate hourly depreciation for machinery. This is crucial for understanding equipment costs. Does anyone know what depreciation means?
Isn't depreciation how much value something loses over time?
Exactly! Now, when we talk about hourly depreciation, we’re focusing on how much value is lost for each hour the equipment is in use. One essential formula we will use today is for the annualized cost, represented as \( A = \frac{i(1+i)^n}{(1+i)^n - 1} \).
What do the letters stand for?
Great question! \( i \) represents the interest rate, \( n \) is the number of years. In our example, the initial cost of the equipment is ₹2,89,00,000. Let's dive deeper!

Let’s apply the formula we discussed. For our case with an interest rate of 8% and a lifespan of 12.5 years, can someone calculate the annualized cost?
I think it would come to about ₹37,41,844.41!
Correct! This cost helps us understand how to distribute the initial investment over the lifetime of the machine. Now, let’s examine the salvage value and its importance in our calculations.
How does that work?
The salvage value is what we can recover at the end of the machine's life. We calculate it as a uniform annual cost too, using a similar formula. Let's compute that.
Deriving Hourly Depreciation

With our annualized initial cost and annualized salvage value, we can now determine the hourly depreciation. It's simply the annualized cost minus the salvage value divided by the total hours of usage per year.
So if I remember, it's ₹2159.92 per hour?
Exactly! And remember, this is just one aspect of the total cost. We must factor in insurance and taxes as well, calculated similarly.
How do these costs affect the overall ownership cost?
Great inquiry! When we sum up all these hourly costs, we arrive at our total hourly ownership cost, which was ₹3063.05. Understanding each component is crucial for accurate budgeting.

Let's recap the total costs involved. We need to consider everything, such as depreciation, insurance, and taxes. Can someone summarize these components?
Sure! We have hourly depreciation of ₹2159.92, insurance at ₹361.25, and taxes at ₹541.88.
Perfect! And combining those gives us our total hourly ownership cost of ₹3063.05. This total gives us a clearer picture of the machine's cost-effectiveness.
Why is it essential to understand all of these costs?
Excellent question! It helps businesses budget properly and make informed decisions about machine ownership and investment. Let's summarize everything we've learned today.
Introduction & Overview
Read summaries of the section's main ideas at different levels of detail.
Quick Overview
Standard
The section details how to calculate the hourly depreciation for machinery based on its initial cost, salvage value, and annual usage. It discusses the uniform series capital recovery factor and the conversion of costs and values into annual equivalents, before deriving the total hourly ownership cost.
Detailed
In this section, we explore the nuances of calculating hourly depreciation for machinery, critical for effective cost management in equipment ownership. The initial cost of equipment is expressed as an annualized cost through the uniform series capital recovery factor formula: \( A = \frac{i(1+i)^n}{(1+i)^n - 1} \). In the context given, an initial cost of ₹2,89,00,000 and an interest rate of 8%, over a useful life of 12.5 years, results in an annualized cost of ₹37,41,844.41. Additionally, the section covers transforming the future salvage value into an equivalent annual cost, leading to the formulation of hourly depreciation, which is derived from the total cost minus the salvage value divided by the annual usage hours. This results in an hourly depreciation of ₹2159.92. Other ownership costs, such as insurance and taxes, are then calculated similarly, leading to a total hourly ownership cost of ₹3063.05, incorporating all essential factors to consider for a comprehensive analysis.

Initial Cost and Its Annualized Equivalent
Chapter 1 of 5

Chapter Content
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.
Detailed Explanation
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.
Examples & Analogies
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.
Calculating the Salvage Value

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

Chapter Content
Hourly Depreciation = (Annualized Initial Cost - Annualized Salvage Value) / Annual Use in Hours
= (37,41,844.41 - 2,85,968.88) / 1600
= ₹ 2159.92/hr.
Detailed Explanation
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.
Examples & Analogies
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.
Calculating Additional Ownership Costs

Chapter Content
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.
Detailed Explanation
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.
Examples & Analogies
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.
Detailed Explanation
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.
Examples & Analogies
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.
