After-Tax Salvage Value Calculator

Enter the salvage value, book value and tax rate to get the after-tax salvage value.

How it is calculated

The tool computes tax = (salvage − book value) × tax rate ÷ 100 and after-tax salvage = salvage − tax. Salvage is the cash you expect from selling the asset, book value is its remaining depreciated value on the books, and the tax rate is a percentage between 0 and 100. The same tax rate is applied to the whole difference. When the sale price is below book value there is a loss, so the tax shows as a negative number and the after-tax figure is higher than the sale price, treating the loss as a tax saving. Whether that is allowed depends on the country, the asset type and the company's other income, and some jurisdictions tax asset sales differently, so check the local rules. Inputs cannot be negative.

Worked example

An asset can be sold for 50,000 and has a book value of 30,000, with a 25% tax rate. The gain is 50,000 − 30,000 = 20,000, so tax = 20,000 × 0.25 = $5,000.00. After-tax salvage = 50,000 − 5,000 = $45,000.00. If the sale price were only 20,000, the loss of 10,000 would give a tax of −2,500 and an after-tax value of 22,500.

Common mistakes

  • Entering the original purchase cost as book value. Book value is cost less accumulated depreciation, and using cost can show a loss where there is really a taxable gain.
  • Typing the tax rate as 0.25. The field is a percentage, so 25 is correct and 0.25 would mean 0.25%.
  • Applying tax to the full salvage value. Only the amount above book value is taxed in this method, not the whole sale price.
  • Ignoring that a loss shows as negative tax. The tool credits it as a tax saving, which may not apply when the company cannot use the loss.
  • Mixing depreciation methods: the book value must match the method used for tax, which may differ from the accounting books.

About this calculator

When a company disposes of an asset at the end of its useful life, the cash it actually keeps isn't the full salvage (resale) value — if the sale price exceeds the asset's remaining book value, that gain is taxable, and if it falls short, the loss produces a tax saving. The after-tax salvage value is salvage value − [tax rate × (salvage value − book value)], giving the true net cash the company pockets.

This figure is a required input in capital budgeting analyses like NPV and IRR, where it forms the terminal cash flow at the end of a project's life. Corporate finance analysts use it to avoid overstating a project's profitability by ignoring the tax owed on any gain over depreciated book value.

    Book value is the figure that matters most here, and it should come from your depreciation schedule, not the purchase price. The tool taxes only the difference between the sale and book value, so a sale at exactly book value shows no tax. When the sale is below book value the tax line turns negative, which only helps if your jurisdiction lets a loss offset other income. Do you treat gains on asset sales as ordinary income?
