Understanding Appliance Depreciation (Straight-Line Method)
What is Depreciation?
Depreciation is the accounting method used to allocate the cost of a tangible asset over its useful life. Assets like appliances lose value over time due to wear and tear, obsolescence, or age. Calculating depreciation helps determine an asset's current book value.
Straight-Line Depreciation Method
The straight-line method is the simplest way to calculate depreciation. It assumes the asset depreciates by the same amount each year over its useful life.
Key Terms:
- Original Purchase Price (Cost): The initial cost of acquiring the asset.
- Salvage Value: The estimated resale value of the asset at the end of its useful life. This is the value the asset is expected to be worth after it has been fully depreciated.
- Useful Life: The estimated number of years an asset is expected to be productive or usable.
- Current Age: The current age of the appliance since purchase.
Formulas:
Annual Depreciation:
(Original Cost - Salvage Value) / Useful Life
Total Depreciation (to Date):
Annual Depreciation * Current Age
(Capped at Original Cost - Salvage Value)
Current Book Value:
Original Cost - Total Depreciation
(Cannot go below Salvage Value)
Example Calculation (Manual)
Suppose you bought a refrigerator for $1200 with an estimated useful life of 12 years and a salvage value of $200. It is currently 5 years old.
Annual Depreciation: ($1200 - $200) / 12 years = $1000 / 12 ≈ $83.33 per year.
Total Depreciation: $83.33/year * 5 years ≈ $416.65.
Current Book Value: $1200 - $416.65 = $783.35.

Example 1: New Refrigerator
Scenario: Calculate depreciation for a brand new refrigerator.
Inputs: Cost = $1500, Salvage = $150, Useful Life = 15 years, Age = 0 years.
Calculation:
- Annual Depreciation = ($1500 - $150) / 15 = $1350 / 15 = $90
- Total Depreciation = $90 * 0 = $0
- Book Value = $1500 - $0 = $1500
Result: Annual Dep: $90.00, Total Dep: $0.00, Book Value: $1,500.00.
Conclusion: A new appliance has not depreciated yet.
Example 2: Mid-Life Washing Machine
Scenario: A washing machine is halfway through its estimated life.
Inputs: Cost = $800, Salvage = $100, Useful Life = 10 years, Age = 5 years.
Calculation:
- Annual Depreciation = ($800 - $100) / 10 = $700 / 10 = $70
- Total Depreciation = $70 * 5 = $350
- Book Value = $800 - $350 = $450
Result: Annual Dep: $70.00, Total Dep: $350.00, Book Value: $450.00.
Conclusion: At 5 years old, its book value is estimated at $450.
Example 3: Fully Depreciated Dryer
Scenario: Calculate depreciation for a dryer that is past its useful life.
Inputs: Cost = $600, Salvage = $50, Useful Life = 12 years, Age = 15 years.
Calculation:
- Annual Depreciation = ($600 - $50) / 12 = $550 / 12 ≈ $45.83
- Max Depreciation = $600 - $50 = $550
- Since Age > Useful Life, Total Depreciation = Max Depreciation = $550
- Book Value = Cost - Total Depreciation = $600 - $550 = $50 (Equals Salvage Value)
Result: Annual Dep: $45.83, Total Dep: $550.00, Book Value: $50.00.
Conclusion: The dryer is fully depreciated, its book value is its salvage value.
Example 4: TV (considered an appliance)
Scenario: Calculate depreciation for a television.
Inputs: Cost = $900, Salvage = $80, Useful Life = 8 years, Age = 2 years.
Calculation:
- Annual Depreciation = ($900 - $80) / 8 = $820 / 8 = $102.50
- Total Depreciation = $102.50 * 2 = $205.00
- Book Value = $900 - $205.00 = $695.00
Result: Annual Dep: $102.50, Total Dep: $205.00, Book Value: $695.00.
Conclusion: The TV's book value after 2 years is $695.
Example 5: Dishwasher with Zero Salvage
Scenario: A dishwasher with no expected salvage value.
Inputs: Cost = $750, Salvage = $0, Useful Life = 10 years, Age = 4 years.
Calculation:
- Annual Depreciation = ($750 - $0) / 10 = $750 / 10 = $75
- Total Depreciation = $75 * 4 = $300
- Book Value = $750 - $300 = $450
Result: Annual Dep: $75.00, Total Dep: $300.00, Book Value: $450.00.
Conclusion: If salvage value is zero, the entire cost is depreciated over the useful life.
Example 6: Microwave Oven
Scenario: Calculate depreciation for a microwave.
Inputs: Cost = $200, Salvage = $20, Useful Life = 7 years, Age = 6 years.
Calculation:
- Annual Depreciation = ($200 - $20) / 7 = $180 / 7 ≈ $25.71
- Total Depreciation = $25.71 * 6 ≈ $154.26
- Book Value = $200 - $154.26 = $45.74
Result: Annual Dep: $25.71, Total Dep: $154.29, Book Value: $45.71.
Conclusion: The microwave's book value after 6 years is about $45.71.
Example 7: Oven/Stove Range
Scenario: Calculate depreciation for a kitchen range.
Inputs: Cost = $1100, Salvage = $120, Useful Life = 14 years, Age = 8 years.
Calculation:
- Annual Depreciation = ($1100 - $120) / 14 = $980 / 14 = $70
- Total Depreciation = $70 * 8 = $560
- Book Value = $1100 - $560 = $540
Result: Annual Dep: $70.00, Total Dep: $560.00, Book Value: $540.00.
Conclusion: The range's book value after 8 years is $540.
Example 8: Air Conditioner (Window Unit)
Scenario: Calculate depreciation for a window AC unit.
Inputs: Cost = $300, Salvage = $30, Useful Life = 9 years, Age = 9 years.
Calculation:
- Annual Depreciation = ($300 - $30) / 9 = $270 / 9 = $30
- Max Depreciation = $300 - $30 = $270
- Since Age = Useful Life, Total Depreciation = Max Depreciation = $270
- Book Value = Cost - Total Depreciation = $300 - $270 = $30 (Equals Salvage Value)
Result: Annual Dep: $30.00, Total Dep: $270.00, Book Value: $30.00.
Conclusion: The AC unit is fully depreciated at the end of its useful life.
Example 9: Vacuum Cleaner

Inputs: Cost (Used) = $500, Salvage = $50, Useful Life (Remaining) = 7 years, Age (Since Used Purchase) = 3 years.
Calculation: (Apply calculation based on your purchase cost and remaining useful life)
- Annual Depreciation = ($500 - $50) / 7 = $450 / 7 ≈ $64.29
- Total Depreciation = $64.29 * 3 ≈ $192.87
- Book Value = $500 - $192.87 = $307.13
Result: Annual Dep: $64.29, Total Dep: $192.86, Book Value: $307.14.
Conclusion: Depreciation can be calculated from the point of purchase, using the remaining useful life and salvage value from that point.
Frequently Asked Questions about Appliance Depreciation
1. What is depreciation?
Depreciation is how businesses and individuals account for the loss of value of an asset over time due to usage, age, or becoming outdated. It spreads the cost of the asset over its useful life.
2. Why should I calculate appliance depreciation?
For businesses, it's crucial for accounting, taxes, and understanding the true cost of owning assets. For individuals, it helps estimate the current value of an appliance for insurance purposes, potential resale, or simply understanding wealth.
3. What is the "Straight-Line Method"?
It's the simplest depreciation method, assuming an asset loses the same amount of value each year over its useful life until it reaches its salvage value.
4. What is "Useful Life"?
Useful life is the estimated period (in years or usage hours) an asset is expected to be functional and productive. For appliances, it's typically an estimate based on average lifespan.
5. What is "Salvage Value"?
Salvage value is the estimated value of an asset at the end of its useful life. It's what you expect to sell it for, sell for parts, or its scrap value after you are done using it.
6. What is "Book Value"?
Book value is the asset's value recorded on the balance sheet (or in your personal records). It's the original cost minus the accumulated depreciation calculated up to a specific date.
7. How does this calculator handle an appliance older than its useful life?
If the current age is equal to or greater than the useful life, the calculator assumes the appliance is fully depreciated. Its total depreciation will be capped at the original cost minus the salvage value, and its book value will be equal to the salvage value.
8. Is this the only way to calculate depreciation?
No, other methods exist, like the declining balance method or sum-of-the-years'-digits method, which depreciate assets faster in the early years. The straight-line method is the most basic and often used for simplicity.
9. Can I use this for any type of asset?
While designed for appliances, the Straight-Line method can be applied to many tangible assets (vehicles, furniture, equipment), provided you can estimate the cost, salvage value, and useful life.
10. Does this calculator predict the market resale value?
No, book value is an accounting concept. The actual market value or resale price of an appliance can be higher or lower than its book value, influenced by condition, demand, brand, etc.
