How it's calculated

Frequently asked questions
Which method should I use?
Straight-line is simplest and common for financial statements. Accelerated methods front-load expenses for assets that lose value quickly, like vehicles and computers.
Is this MACRS for US taxes?
No. MACRS uses IRS-specific tables and conventions; ask your tax preparer or use IRS Publication 946.
What's salvage value?
What you expect the asset to be worth at the end of its useful life.
