Residual Value Calculator
Estimate an asset's residual value from its original cost, annual depreciation and useful life. Enter three figures to see the remaining value at the end of the asset's service period.

Residual Value Formula
Where:
- \(C\) — original cost of the asset (purchase price)
- \(D\) — annual depreciation expense
- \(Y\) — useful life of the asset in years
The formula assumes straight-line depreciation: the asset loses the same amount of value each year, so the residual value is the original cost minus the total depreciation accumulated over its useful life.
Residual Value – Calculation Example
Example: a company buys a machine for $10,000, depreciates it by $1,000 per year, and expects to use it for 5 years.
\[ \text{Residual Value} = 10{,}000 - (1{,}000 \times 5) = 10{,}000 - 5{,}000 = 5{,}000 \]
Result: the residual value is $5,000 — the machine's estimated worth after 5 years of use.
How to use the calculator
- Enter the Original cost of asset — the initial purchase price, including installation or delivery costs if they were capitalized.
- Enter the Annual depreciation — the depreciation expense charged per year under the straight-line method.
- Enter the Useful life (years) — the total number of years the asset is expected to remain in service.
- Read the Residual Value in dollars, together with the interpretation line that tells you whether the asset still holds value, is fully depreciated, or has been over-depreciated.
What is residual value?
Residual value (also called salvage value or scrap value) is the amount an asset is expected to be worth at the end of its useful life or lease term. It is what you could realistically sell the asset for once it has served its purpose — whether that is a vehicle coming off a lease, a machine being replaced, or equipment being resold on the second-hand market.
Residual value matters because it anchors several financial decisions. In accounting, it determines how much of an asset's cost must be depreciated: total depreciation equals original cost minus residual value. In leasing, the residual value is one of the main drivers of the monthly payment — the higher the expected value at lease end, the less value the lessee consumes and the lower the payments. In capital budgeting, terminal or residual values feed directly into project valuations and return calculations.
Interpreting the result is straightforward. A positive residual value means the asset should still be worth something after its useful life. A result of zero means the asset is expected to be fully depreciated with no recoverable value. A negative result is a warning sign: your annual depreciation times the useful life exceeds the original cost, which is not possible under straight-line depreciation — the annual depreciation should be at most \(C / Y\), or lower if you expect a salvage value.
To estimate annual depreciation yourself when you know the expected residual value, you can rearrange the formula: \(D = (C - \text{Residual Value}) / Y\). For a fuller picture of how depreciation builds up over time — including methods that front-load the expense — see our Asset Depreciation and Accelerated Depreciation calculators.
Assumptions, limitations and practical tips
- Straight-line method only. The calculator assumes the asset loses an equal amount of value each year. Under declining-balance or sum-of-years-digits methods, the book value at a given year differs from this result — use the Accelerated Depreciation calculator for those cases.
- Residual value is an estimate. Actual resale prices depend on market conditions, wear, technology changes and demand. For vehicles and equipment, compare against current second-hand market prices for similar assets of the same age.
- Check the negative-result warning. If the calculator returns a negative residual value, your inputs are inconsistent: reduce the annual depreciation or shorten the useful life so that \(D \times Y \le C\).
- Tax rules may cap residual value. Many tax jurisdictions set minimum salvage values or prescribe depreciation schedules; confirm your inputs against the rules that apply to your asset class.
- Use it for leases too. In leasing, residual value often means the projected value of the asset at lease end rather than zero — the same formula applies when estimating a buyout price or a lease's depreciation component.
For natural-resource assets, where value is consumed through extraction rather than use over time, the equivalent concept is covered by our Depletion Expense calculator.
Frequently Asked Questions
What is a good residual value percentage?
It depends on the asset class. New cars typically retain about 50–60% of their price after 3 years and 35–45% after 5 years. Industrial machinery often ends up at 10–20% of original cost, while computers and phones can fall below 10% quickly due to obsolescence. Divide the residual value by the original cost and multiply by 100 to get the percentage, then compare it with typical figures for similar assets of the same age.
Is residual value the same as salvage value and book value?
Residual value, salvage value and scrap value are essentially synonyms — the estimated worth of an asset at the end of its useful life. Book value is different: it is the asset's value on the balance sheet today, i.e. original cost minus accumulated depreciation so far. Book value equals residual value only on the final day of the asset's service life, and only if the estimate was accurate.
How do I express residual value as a percentage of cost?
Divide the residual value by the original cost and multiply by 100: \( \text{Residual \%} = \frac{\text{Residual Value}}{C} \times 100 \). For example, a $10,000 machine with a $5,000 residual value keeps 50% of its value. This percentage is handy for benchmarking against industry norms and for setting depreciation rates in leases.
Can I use this calculator to estimate a car lease buyout price?
Yes, with care. Enter the vehicle's original price, the annual depreciation implied by your lease (total depreciation divided by the lease term), and the number of years in the lease. The result approximates the projected value at lease end — the basis of a buyout. However, actual buyout prices in real contracts are set by the leasing company and may include fees, so treat this as an estimate, not a contractual figure.
Should removal or disposal costs be subtracted from residual value?
In accounting, yes — if you will incur costs to dismantle, remove or dispose of the asset, many frameworks allow (or require) netting them against the salvage estimate. That lowers the residual value and increases total depreciation. For a quick market estimate, though, most people use gross resale value. If disposal costs are significant, subtract them before entering the figure into any valuation.
I only know the depreciation rate, not the annual amount. How do I use the calculator?
Convert the rate into an annual amount first: multiply the original cost by the rate. A 20% declining rate on a $10,000 asset means roughly \(10{,}000 \times 0.20 = 2{,}000\) per year — but note that percentage rates usually imply declining-balance depreciation, where the yearly amount shrinks over time. For declining-balance or double-declining methods, use a dedicated accelerated depreciation calculator instead of this straight-line one.
Why does my actual resale price differ from the calculated residual value?
Because residual value is a forecast, not a guarantee. Real sale prices shift with market demand, wear and tear, technology obsolescence, and timing — a forced quick sale usually brings less. Before selling, check current listings for the same asset model and age. If the gap is large and consistent, update your depreciation assumptions for future purchases; for tax reporting, follow the rules that apply in your jurisdiction rather than market quotes.
