Sum of the Years Digits Method
Unlock Audio Lesson
Today, we're going to learn about the Sum of the Years Digits method. This method helps us calculate depreciation based on the age of the asset. Can anyone explain what depreciation means?
Is it the reduction in value of an asset over time?
Exactly! Now, how do we use the Sum of the Years Digits method? If we have a machinery with a useful life of 9 years, what is the first step?
We need to calculate the total of the years, which is 1+2+3 and so on up to 9, right?
Correct! So, the total would be 45. If we consider the first year for depreciation, we would take 9 divided by 45. Can anyone tell me what this would give us?
That would be 0.2, or 20% of the depreciable base.
Well done! We multiply this by your initial cost minus any salvage value to find the depreciation for the year.
What happens in the ninth year, specifically?
Great question! For the ninth year, you would take 1 divided by 45 again. Can anyone calculate what that would represent?
That would just be a tiny fraction since it’s the last year.
Exactly! It emphasizes the declining factor of depreciation over the life of an asset. Let's recap: the SYD method gives more depreciation to early years and less as the asset ages.
Double Declining Balance Method
Unlock Audio Lesson
Now let’s talk about the Double Declining Balance method. What do you think makes it different from what we’ve just discussed?
It doesn’t consider salvage value when calculating yearly depreciation, right?
Exactly! We focus solely on the book value. For the first year, if our initial cost is ₹82,00,000 and we deduct the tire cost, what will be our book value?
It would be ₹76,00,000 after removing the tire costs!
Perfect! Now to find the first-year depreciation, we multiply the book value by 2 divided by the number of remaining years. Can anyone calculate that?
So for the first year that would be ₹76,00,000 multiplied by 2/9?
Right again! But remember, you need to keep monitoring that book value. What happens if, by year eight, the book value drops below the salvage value?
We have to back-calculate or switch methods, right?
Exactly! You would revert to the straight line method to ensure it doesn’t drop below the salvage value.
Comparison ofMethods and Application
Unlock Audio Lesson
Having learned both methods, let’s compare their effectiveness. Which method would typically yield higher depreciation in the early years?
I think the Double Declining Balance method would!
Absolutely! It provides accelerated depreciation. Why do businesses prefer higher depreciation early on?
Probably for tax benefits or better cash flow in those years?
Exactly! Now, can you summarize when it would be appropriate to switch from one method to another?
If the DDB depreciation is higher initially but might lead the book value below the salvage value, we switch to straight line!
Correct! So, remember, the goal is to manage book value wisely against salvage value. Excellent discussion today!
Introduction & Overview

Quick Overview
Standard
The section outlines two key depreciation methods: the Sum of the Years Digits Method and the Double Declining Balance Method. It demonstrates how to determine depreciation for each year, particularly the ninth year, and emphasizes the significance of ensuring that the book value does not fall below the salvage value.
Detailed
Detailed Overview of Depreciation Calculation for the Ninth Year
This section provides an in-depth exploration of depreciation calculations focusing on the ninth year of an asset's useful life. It discusses two primary methods: Sum of the Years Digits (SYD) and Double Declining Balance (DDB).
- Sum of the Years Digits Method: This method calculates depreciation by dividing the number of years remaining by the total number of years of life left. For instance, when calculating the depreciation for the ninth year, you would take 1 (year left) and divide it by the total years left, which is the sum of years from 1 to 9./
- Double Declining Balance Method: This method, contrastingly, does not factor in the salvage value in the depreciation calculations. Instead, it utilizes the book value at the start of the year and applies a twice-the-straight-line depreciation rate. During this process, care is required to monitor the book value, ensuring it does not drop below the salvage value, often necessitating a switch to another depreciation method.
In summary, understanding these methods is crucial, as they not only affect financial reporting but also have significant implications for tax liabilities and asset management.

Sum of the Years Digit Method: First Year Calculation

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, identify the total number of years for which the asset will be useful. In this case, it is 9 years. You need to divide the remaining years (which is 9 in the first year) by the sum of all the years in the useful life (1 through 9). The sum of these numbers is 45 (1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 = 45). Then, subtract the salvage value and tire cost from the initial cost and multiply by the fraction calculated. This will yield the depreciation amount for the first year.
Examples & Analogies
Imagine you bought a car for ₹8,200,000. You can expect it to be useful for 9 years. During each year, the value of the car declines. In the first year, you look at how long you’ll use it (9 years) and calculate how much it should lose in value by spreading the total expected loss over the timeframe. By the first year, you're estimating that it will lose ₹1,280,000 of its value.
Second Year Depreciation Calculation

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.
Detailed Explanation
For the second year, you again use the sum of the years digit method. Now, the number of years left in the recovery period is 8 (since one year has passed). You apply the same formula: divide 8 by the total sum of the years (still 45) and multiply the initial cost minus tire cost and salvage value by this fraction. The calculation will provide the depreciation amount for the second year.
Examples & Analogies
Returning to our car example, by the second year, the car isn’t as new. The valuation drop continues, so you calculate the loss in value for that year just like before, but now you have 8 years left instead of 9, which affects how much you say it lost this year.
Ninth Year Depreciation Calculation

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
For the ninth year, you are left with just 1 year of utilization. Using the sum of years digit method, the fraction is 1 divided by the sum of years, which is still 45. The formula remains the same where you subtract the salvage value and tire cost from the initial cost and multiply by this new fraction. This calculation provides the depreciation for the last year of the machine's useful life.
Examples & Analogies
It’s akin to the final stretch in a marathon. As you approach the end, your energy (value) diminishes less dramatically than it did at the start. For your car, now it’s just one last year of value loss you’re calculating as you watch its worth dwindle closer to what you’d get if you sold it.
Understanding Depreciation Estimates

So, this is all the estimated depreciation using sum of the years digit method.
Detailed Explanation
The sum of the years digit method allows for a structured, declining depreciation while recognizing that assets lose value more rapidly in their early years. By constantly recalculating based on remaining useful life, this method keeps depreciation amounts relevant to the current state and expected performance of the asset.
Examples & Analogies
Think of a new smartphone that loses a lot of value within the first year as new models come out; its depreciation aligns more closely with how quickly it loses worth initially rather than uniformly every year. This method mimics that pattern.

If a machine costs ₹82,00,000 with a salvage value of ₹12,00,000 and tire costs of ₹6,00,000, the first year’s SYD depreciation is calculated by using the formula: (9/45) * (₹82,00,000 - ₹12,00,000 - ₹6,00,000).
-
For DDB, starting with a book value of ₹76,00,000 for the first year and calculating depreciation as (2/9) * ₹76,00,000 gives ₹16,88,888 depreciation for that year.
