Appliance Depreciation Calculator

Everyday Life

The Appliance Depreciation Calculator uses straight-line depreciation to show how an appliance loses value over time. It divides the original cost by the useful life to get annual depreciation, then multiplies by the years used. The formula used is: Annual = Cost ÷ Life | Total = Annual × Years Used.

Formula

Annual = Cost ÷ Life | Total = Annual × Years Used
  • The Appliance Depreciation Calculator updates instantly as you change the cost, life, or years used.
  • Formula: Annual = Cost ÷ Life | Total = Annual × Years Used
  • Input definitions: • Original Cost: the price you paid for the appliance • Useful Life: how many years the appliance is expected to last • Years Used: how long you have owned it so far
  • This uses straight-line depreciation, spreading the cost evenly across the useful life.
  • Remaining value = original cost − total depreciation, and it should not be treated as resale or market value.
  • Useful life is an estimate; choosing a shorter life increases annual depreciation.

Example Calculation

Inputs
  • Original Cost (PKR): 1000000
  • Useful Life (years): 20
  • Years Used: 5

For an appliance costing 1,000,000 with a 20-year life used for 5 years: annual = 1,000,000 ÷ 20 = 50,000; total = 50,000 × 5 = 250,000; remaining value = 1,000,000 − 250,000 = 750,000.

Frequently asked questions

What is straight-line depreciation?
It spreads an asset's cost evenly over its useful life, so each year loses the same amount of value: cost ÷ useful life.
How is remaining value found?
Subtract the total depreciation so far from the original cost. It is a book value, not necessarily the resale price.
What useful life should I use?
Use a realistic expected lifespan for the appliance — often 10 to 20 years for large appliances. A shorter life means faster depreciation.
Does this match market value?
Not exactly. Straight-line depreciation is an accounting estimate; actual resale value depends on condition, brand, and demand.
Can I use this for taxes?
It gives a basic estimate, but tax depreciation rules vary by country and asset class. Check local guidance for official figures.
