What This Calculator Does
This depreciation calculator helps accountants, bookkeepers, tax preparers, and business owners calculate asset depreciation using three methods: straight-line, 200% declining balance, and MACRS (Modified Accelerated Cost Recovery System). It generates a full year-by-year depreciation schedule showing annual depreciation, accumulated depreciation, and book value. The MACRS method includes all standard IRS property classes (3, 5, 7, 10, 15, and 20-year) with half-year convention rates and optional 2026 bonus depreciation at 20%.
The Formula
Straight-line depreciation spreads the depreciable cost evenly over the asset's useful life. Declining balance front-loads depreciation by applying a fixed rate (200% of straight-line) to the remaining book value each year. MACRS is required for federal tax purposes and uses IRS-published percentage tables based on property class and convention. MACRS assumes zero salvage value. Bonus depreciation allows an additional first-year deduction, which is 20% for assets placed in service in 2026 (phasing down from 100% in 2022).
Step-by-Step Example
Enter asset details
Asset cost: $50,000. Select MACRS method with 5-year property class (computers, vehicles, office equipment).
Apply bonus depreciation
Enable 2026 bonus depreciation (20%). First-year bonus: $10,000. Remaining MACRS basis: $40,000.
Review the schedule
Year 1: $10,000 bonus + $8,000 MACRS = $18,000. Year 2: $12,800. Year 3: $7,680. Year 4: $4,608. Year 5: $4,608. Year 6: $2,304.
Verify total depreciation
Total depreciation equals the full $50,000 cost basis. Book value at end of schedule: $0.

Common Mistakes to Avoid
Using MACRS for financial statement (book) purposes. MACRS is a tax method only. GAAP requires straight-line or another systematic method for financial reporting.
Forgetting the half-year convention in MACRS. The first and last years of the MACRS schedule reflect a half-year of depreciation, which is why a 5-year property has 6 rows in the schedule.
Not tracking the bonus depreciation phase-down. Bonus depreciation is 20% for 2026, down from 40% in 2025, 60% in 2024, and 80% in 2023. It drops to 0% for 2027 unless Congress extends it.
Depreciating land. Land is not a depreciable asset. Only the building and improvements on the land can be depreciated.
Exceeding the Section 179 deduction limit. The 2026 Section 179 limit is $1,250,000 with a phase-out beginning at $3,130,000 in total asset purchases.
