Question 1

Which depreciation method should I use?

Accepted Answer

Straight-line is simplest; DDB accelerates early write-offs; SYD is a middle ground; Units-of-production ties expense to usage.

Question 2

How is salvage value handled?

Accepted Answer

Depreciation stops once the book value reaches the estimated salvage value.

Question 3

Can I switch methods?

Accepted Answer

Some policies allow switching from accelerated (DDB) to straight-line when it yields higher expense; follow your accounting policy.

Question 4

What about partial-year assets?

Accepted Answer

Prorate the first/last year by months in service or use a convention (e.g., half-year).

Question 5

Is this tax advice?

No—this tool is for general planning; consult your accountant for tax rules.
