A depreciation calculator turns an asset's original cost, its estimated salvage value, and its useful life into a clear, year-by-year depreciation schedule. NeftCal's tool supports three methods — straight-line, double-declining balance (200%), and 150% declining balance — so you can see exactly how much depreciation expense to record each year, what the asset's book value is at any point in its life, and how the choice of method changes the timing of the expense. It is built for business owners preparing financial statements, accountants running month-end and year-end closes, and finance teams budgeting around fixed assets like machinery, vehicles, computer equipment, and furniture.
Depreciation matters for two reasons. For accounting, it matches the cost of a long-lived asset against the revenue it helps generate across its useful life — the annual figure is the depreciation expense on the income statement, and the running total is accumulated depreciation on the balance sheet. For tax planning, depreciation is a non-cash expense that reduces taxable income each year, so the method and useful life you choose directly affect the taxes a business owes. An accelerated method shifts more expense into the early years, which can lower near-term tax bills, even though total depreciation over the asset's life is the same under any method.
Business owners tracking the value of their capital equipment, accountants preparing depreciation schedules for bookkeeping and tax work, finance teams modeling a capital purchase before it is made, and students or analysts learning how depreciation works. Pair the output with a business tax calculator to estimate the tax impact of the deduction, and a cash flow calculator to see how a non-cash expense like depreciation sits alongside actual cash movements.
Because total depreciation over an asset's life is always Cost − Salvage Value, the method you pick changes only the timing, not the total. Accelerated methods exploit this: larger deductions in the early years can free up cash for a growing business, while straight-line gives the even, predictable expense that is easiest to plan and report against. Knowing which method to apply, and to which assets, is a core part of asset management, financial reporting, and tax planning.
Straight-line spreads cost evenly across the asset's life; declining balance applies a fixed rate to the remaining book value
The simplest method — the same depreciation expense every year, easy to plan and forecast against.
Front-loads larger deductions early, better matching assets that lose value quickly and useful for accelerating tax benefits.
Depreciation lowers reported profit and taxable income but doesn't itself use any cash — the cash was already spent at purchase.
From asset details to a full depreciation schedule in under a minute
Input the original purchase price of the asset, including any setup, delivery, or installation costs that form part of its cost basis.
Input the estimated resale or scrap value at the end of the asset's useful life. The calculator requires this to be less than the asset cost.
Input the number of years the asset is expected to be in service, from 1 to 50 years. Choose a life that matches both your expected use and the class life your tax authority allows.
Select Straight-Line, Double-Declining Balance (200%), or 150% Declining Balance. Straight-line spreads cost evenly; the two declining balance methods accelerate the expense into the early years.
See the Year 1 depreciation expense, annual depreciation, total depreciation over the asset's life, and the final book value, which you can compare against the salvage value.
Use the year-by-year depreciation schedule and the book value chart to see how the asset loses value, and export a plain-text report if you need a record for your books.
A delivery vehicle depreciated under straight-line and double-declining balance, step by step
Suppose a company buys a delivery vehicle for $50,000 and expects it to be worth $5,000 at the end of a 5-year useful life. The depreciable base is $45,000. Under the straight-line method, the expense is spread evenly; under double-declining balance, a 40% rate is applied to the remaining book value each year.
Explanation: With straight-line, this vehicle produces an identical $9,000 expense in each of its five years and its book value declines in a straight line from $50,000 to exactly the $5,000 salvage value — a predictable schedule that is easy to budget against. With double-declining balance, the same vehicle produces a $20,000 expense in Year 1 that shrinks to $1,480 by Year 5. Note the final-year plug: without the cap, Year 5 depreciation would be $2,592 and book value would fall to $3,888, below salvage, so the calculator books only $1,480 to land exactly on $5,000. Total depreciation is $45,000 under both methods — the choice changes timing, not the total.
150% declining balance comparison: selecting the 150% method gives a rate of 1.5 ÷ 5 = 30%. Depreciation runs $15,000, $10,500, $7,350, $5,145, and $3,601.50, leaving a book value of $8,403.50 after Year 5 — because the un-capped amount stays above salvage, the asset is not written all the way down to salvage within five years.
How straight-line and declining balance change the pattern of the same $50,000 asset
For the $50,000 vehicle with a $5,000 salvage value and 5-year life, the two methods produce the same total depreciation but very different year-by-year expenses. The table below walks the schedule year by year. These are the actual figures the calculator computes for these inputs.
| Year | Straight-Line Depreciation | Straight-Line Book Value | Double-Declining Depreciation | Double-Declining Book Value |
|---|---|---|---|---|
| 1 | $9,000 | $41,000 | $20,000 | $30,000 |
| 2 | $9,000 | $32,000 | $12,000 | $18,000 |
| 3 | $9,000 | $23,000 | $7,200 | $10,800 |
| 4 | $9,000 | $14,000 | $4,320 | $6,480 |
| 5 | $9,000 | $5,000 | $1,480 | $5,000 |
Reading the Year 1 and Annual boxes: under straight-line, the annual depreciation is the same every year, so the Year 1 and Annual boxes both show $9,000. Under double-declining balance, the "Annual Depreciation" box shows the Year 1 figure of $20,000, and every later year is smaller — use the schedule table for the exact amounts.
Reading Total Depreciation: for straight-line and double-declining balance this equals Cost − Salvage Value ($45,000 here), because both methods force the final book value onto the salvage floor. Under 150% declining balance, the total can be lower and the final book value can sit above salvage, as the worked example shows.
Reading Final Book Value: a result equal to the salvage value means the asset has been fully depreciated to its residual worth. A result above salvage (possible under 150% declining balance) simply means the accelerated rate never pulled book value down to salvage within the useful life.
Typical useful-life assumptions: general reference ranges used in bookkeeping — not a formal standard, and your tax authority's class lives take precedence. Computer equipment 3–5 years, vehicles 5 years, office furniture 5–7 years, machinery 5–10 years, purchased software 3–5 years, buildings 25–40 years.
Risk considerations: this schedule assumes a fixed salvage value, a whole-year useful life, and no partial-year convention or mid-life asset additions. For US tax reporting, the IRS generally requires MACRS, which assigns assets to recovery classes and applies its own rates and conventions — the straight-line and declining balance methods here are book-accounting and planning tools, not MACRS deductions. Confirm the method, useful life, and convention that apply to your actual filing with a licensed tax professional.

Where a depreciation schedule earns its keep in a business
Accelerate depreciation on trucks and vans that lose value quickly, matching the expense to the vehicle's early life.
Short useful lives (3–5 years) make an accelerated method a natural fit for laptops, servers, and office tech.
Model large capital purchases, comparing methods before committing to the spend.
Spread the cost of long-lived property and fit-outs over decades with straight-line.
Plan the write-off of business software and licenses over their 3–5 year useful life.
Produce the depreciation expense for the income statement and accumulated depreciation for the balance sheet.
Compare how much taxable income each method reduces in the early years of an asset's life.
Use the predictable straight-line expense in multi-year budgets and pricing decisions.
Book value is a common input when lenders assess asset-backed credit lines and equipment loans.
Compare the full cost of owning an asset — including depreciation — against leasing it.
Run the same asset under two methods to see the book-versus-tax timing difference before it surprises you.
Know the remaining book value before selling, replacing, or scrapping an asset, and budget for the gain or loss.
What this depreciation calculator does well, and where it can't replace professional accounting or tax work
How the main depreciation approaches differ on the same asset
| Method | How It Works | Expense Pattern | Best For |
|---|---|---|---|
| Straight-Line | (Cost − Salvage) ÷ Useful Life each year | Even and predictable | Assets that lose value steadily — furniture, buildings, long-life equipment |
| Double-Declining Balance | Book Value × (2 ÷ Useful Life), floored at salvage | Front-loaded, heaviest in Year 1 | Assets that lose value quickly — vehicles, computers, machinery |
| 150% Declining Balance | Book Value × (1.5 ÷ Useful Life), floored at salvage | Accelerated but more moderate than double-declining | A middle-ground acceleration for fast-wearing assets |
| Units-of-Production | (Cost − Salvage) × units produced ÷ estimated total units | Varies with actual use | Equipment and vehicles where wear tracks usage (not offered by this calculator) |
Straight-line and both declining balance methods are offered by this calculator, and all write the asset down to the same total over its life. Units-of-production spreads the cost by actual output rather than time, which suits usage-driven assets, but is not part of this tool.
