About this calculator

How it works

You enter asset cost, salvage value, useful life, method and the year to evaluate. Straight-line: (cost − salvage) ÷ life each year. Double declining balance: book value × 2 ÷ life, never below salvage. Sum-of-years-digits: (life − year + 1) ÷ (life × (life + 1) ÷ 2) × (cost − salvage).

Worked example (illustrative inputs)

Cost $50,000, salvage $5,000, 10 years. Straight-line: $4,500 per year. DDB year 1: 50,000 × 0.2 = $10,000. SYD year 1: 10 ÷ 55 × 45,000 ≈ $8,182.

How to read the result

The tool shows the year's depreciation, accumulated depreciation and end-of-year book value. DDB and SYD put more expense in the early years; all methods reach the same salvage value by the end of life.

When to use it

Use it to compare book value schedules for planning and replacement decisions. Which method applies in your accounts is set by your own accounting policy.

Fonctionnement

Vous saisissez le coût de l'actif, la valeur résiduelle, la durée d'utilité, la méthode et l'année à évaluer. Linéaire : (coût − résiduel) ÷ durée chaque année. Dégressif double : valeur comptable × 2 ÷ durée, jamais sous le résiduel. Somme des chiffres des années : (durée − année + 1) ÷ (durée × (durée + 1) ÷ 2) × (coût − résiduel).

Exemple chiffré (valeurs d'illustration)

Coût 50 000 $, résiduel 5 000 $, 10 ans. Linéaire : 4 500 $ par an. Dégressif double année 1 : 50 000 × 0,2 = 10 000 $. Somme des chiffres année 1 : 10 ÷ 55 × 45 000 ≈ 8 182 $.

Lire le résultat

L'outil affiche l'amortissement de l'année, l'amortissement cumulé et la valeur comptable en fin d'année. Les méthodes accélérées concentrent la charge sur les premières années ; toutes atteignent la même valeur résiduelle en fin de vie.

طريقة الحساب

تُدخل تكلفة الأصل والقيمة المتبقية والعمر الإنتاجي والطريقة والسنة المراد تقييمها. القسط الثابت: (التكلفة − المتبقية) ÷ العمر كل سنة. القسط المتناقص المضاعف: القيمة الدفترية × 2 ÷ العمر، دون النزول تحت القيمة المتبقية. مجموع أرقام السنوات: (العمر − السنة + 1) ÷ (العمر × (العمر + 1) ÷ 2) × (التكلفة − المتبقية).

مثال محسوب (قيم توضيحية)

تكلفة 50,000 $، ومتبقية 5000 $، و10 سنوات. القسط الثابت: 4500 $ سنويًا. المتناقص المضاعف في السنة 1: ‏50,000 × 0.2 = 10,000 $. مجموع الأرقام في السنة 1: ‏10 ÷ 55 × 45,000 ≈ 8182 $.

قراءة النتيجة

تعرض الأداة استهلاك السنة والاستهلاك المتراكم والقيمة الدفترية في نهاية السنة. الطرق المعجّلة تحمّل السنوات الأولى أكثر؛ وكل الطرق تصل إلى القيمة المتبقية نفسها في نهاية العمر.

Frequently asked questions

Which depreciation method should I use?

Straight-line is the standard choice for financial statements because it is simple and predictable. Double-declining balance or sum-of-years-digits make sense when you want to match the expense to an asset that loses value or usefulness quickly (like technology or vehicles), and they also front-load tax deductions.

What is the difference between DDB and SYD?

Both accelerate depreciation into earlier years, but they use different math: DDB applies a fixed percentage to the shrinking book value each year, while SYD allocates a shrinking fraction of the original depreciable base. DDB is typically more aggressive in year one; SYD declines more smoothly.

What happens if I set salvage value to zero?

The full asset cost becomes depreciable. Straight-line and SYD simply divide or allocate the entire cost; DDB still floors the calculation so book value cannot go negative, which effectively means the last year or two absorbs whatever is left.

Why does book value stop changing once it reaches salvage value?

An asset should never be depreciated below its salvage value under any of these methods — once accumulated depreciation reaches cost minus salvage, no more expense is recognized even if useful life remains, because the remaining value represents what you still expect to recover.
