Let's start with the Sum of the Years Digit method. Can anyone tell me what depreciation means?
It’s how we account for the loss of value of an asset over time.
Exactly! This method calculates how much value we lose each year based on the remaining useful life of the asset. Does anyone know how the calculation works?
Is it related to the useful life of the asset?
Yes! We use the number of years left in the recovery period over a sum of years. The formula is `D = (n / Sum of Years) * (Initial Cost - Salvage Value - Tire Cost)`. Let's break it down!
What does 'Sum of Years' mean?
Great question! The 'Sum of Years' is the total of all the years in the asset's useful life. For example, in a 9-year lifespan, it equals 45. So, each year has a decreasing weight.
And that helps us get higher depreciation at first, right?
Exactly! Higher depreciation early on matches the asset's decrease in value. Great job! To summarize, we focus on the years left and calculate depreciation based on that.

Now, let's look at how to apply this method. Suppose an asset costs ₹8,200,000 with a salvage value of ₹600,000 and tire cost of ₹1,200,000. How would we find the year 1 depreciation?
First, we identify 'n', which is 9 years, right?
Exactly! So, we use the formula. What does that give us?
D equals (9 / 45) times (8,200,000 minus 600,000 minus 1,200,000). That gives ₹1,280,000 for year 1!
Spot on! Each subsequent year reduces 'n'. For year 2, 'n' would be 8. What will be the calculation?
So, it would be (8 / 45) times (the same amount), which is approximately ₹1,137,777.78!
Exactly! And this way, we continue calculating for each year until we reach the last. It's a consistent approach.

Quick Overview
Standard
This section details the Sum of the Years Digit method for calculating depreciation, illustrating the steps involved in determining depreciation for various years based on the number of years left in the recovery period. Several examples for each step highlight the calculations involved.
Detailed
The Sum of the Years Digit method is a technique employed to calculate a depreciable asset's depreciation over its useful life. The method allocates a greater portion of the asset's initial cost in earlier years, reflecting the accelerated wear and tear that many assets undergo. The formula given is:
Where:
- D = Depreciation for the current year
- n = Number of remaining years of useful life
- Sum of Years = Sum of all the years from 1 to 'N', with 'N' being the total useful life of the asset.
The section provides practical examples, such as:
1. For a 9-year recovery period, calculating depreciation for year 1 as follows:
- D = (9 / 45) * (8,200,000 - 600,000 - 1,200,000) = ₹ 1,280,000
2. Depreciation for the second year is calculated similarly, using the remaining years. This results in a decreasing depreciation value in subsequent years as 'n' reduces.
The chapter illustrates these principles, emphasizing the significance of using an appropriate method that best aligns with business strategies.

So, here, how do you calculate the depreciation for the first year when you calculate the number of years left in the recovery period is say n = 9. So, number of years left in the recovery period is 9 divided by the sum of the years in the useful life 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 multiplied by initial cost minus the salvage value minus tire cost.
Detailed Explanation
To calculate the depreciation for the first year using the Sum of the Years Digit method, you first identify the remaining recovery period, which is denoted by 'n'. In this case, 'n' is 9, meaning there are 9 years left in the asset's useful life. Next, you calculate the sum of the digits from 1 to 9, which equals 45. The formula for the first year’s depreciation is then:
\[ D = \frac{n}{1+2+3+...+n} \times (\text{initial cost} - \text{salvage value} - \text{tire cost}) \]
Here, the initial cost is the value at which the asset was purchased, the salvage value is the expected residual value at the end of its useful life, and the tire cost is considered separately. Substituting the respective values allows you to find the first year's depreciation amount.
Examples & Analogies
Imagine buying a car for ₹8,200,000, with an expected salvage value of ₹600,000 and tire replacement costs of ₹1,200,000. Think of the Sum of the Years Digit method as deciding how much value your car loses each year based on how old it is. In the first year, because your car has a lot of its value still intact, it depreciates a significant amount. By the 9th year, less of its value is left, thus resulting in a smaller depreciation amount.
Depreciation for the Second Year

Similarly, depreciation for the second year number of years left in the recovery period is nothing but number of years left in the recovery period from the beginning of the second year to the end of the useful life of the machine is 8 year. So divided by the sum of the years in the useful life multiply by a initial cost minus tire cost minus salvage value.
Detailed Explanation
For the second year, you adjust 'n' to reflect the new number of years remaining in the useful life, which is now 8. The formula remains the same, but this time it uses the updated 'n' value:
\[ D = \frac{8}{1+2+3+...+9} \times (\text{initial cost} - \text{tire cost} - \text{salvage value}) \]
This means you are evaluating how much depreciation to apply based on the fact that the asset is now older, and thus has less value to lose. You substitute into the formula to calculate the depreciation for the second year.
Examples & Analogies
Continuing with the same car example, think of it as if your car is now 1 year old. It has lost some of its initial value from the first year and will continue to lose value more gradually during the second year. Now, rather than losing a lot of value like on the first anniversary, it loses a bit less this time around.

Say for the example depreciation for the 9th year it should be number of years left in recovery period will be 1 divided by 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 multiplied by initial cost minus salvage value.
Detailed Explanation
When you reach the 9th year, only 1 year is left in the recovery period. You apply the same formula:
\[ D = \frac{1}{1+2+3+...+9} \times (\text{initial cost} - \text{salvage value}) \]
This reflects that the car is nearing the end of its useful life, and therefore its value drops significantly less compared to the earlier years. The pattern shows a gradual slowing down of depreciation as the asset ages.
Examples & Analogies
Think about your car as it approaches its last year before it's worth that salvage price. By this last year, the depreciation amount is minimal compared to previous years because most of its value has already decreased over time. You can picture it as reaching the final stretch of a marathon run, where the last part is slower and steadier.

So, this is all the estimated depreciation using sum of the years digit method.
Detailed Explanation
In summary, the Sum of the Years Digit method calculates depreciation based on the asset’s declining value over its useful life. The method produces larger depreciation expenses in the earlier years and smaller expenses as time goes on, aligning the depreciation with the asset's actual loss of value. This method serves businesses well by matching depreciation expense to revenues more accurately, particularly in industries where the asset wears down quickly.
Examples & Analogies
Think of it like a new truck used by a delivery company. Early on, it loses value rapidly due to wear and tear from lots of use. However, towards the end of its life, the same truck may be used less, and thus, it doesn't lose value as quickly. This method accurately represents that scenario.
Key Concepts
-
Sum of the Years Digit Method: A depreciation method that accelerates depreciation by applying a fraction of remaining years over the total sum of years.
-
Initial Cost and Salvage Value: The fundamental values from which depreciation calculations take place.
-
Calculation Process: Systematic approach involving the determination of 'n' and using it in a depreciation formula.
Examples & Applications
For an asset with ₹8,200,000 initial cost, ₹600,000 salvage value, and tire cost of ₹1,200,000 over 9 years, year 1 depreciation equates to ₹1,280,000.
In the second year, by calculating with 8 years left in recovery, the depreciation is ₹1,137,777.78.
