Depreciation Rate for Commercial Ovens in Australia (2026 ATO Guide)
What Is the Depreciation Rate for a Commercial Oven in Australia?
According to the Australian Taxation Office (ATO), commercial ovens have a effective life of 12 years. This gives you two depreciation rate options:
| Method | Rate | How It Works |
|---|---|---|
| Diminishing Value | 16.67% | Higher deductions in earlier years |
| Prime Cost | 8.33% | Equal deductions each year |
Diminishing value rate = 200% ÷ effective life (200% ÷ 12 = 16.67%). Prime cost rate = 100% ÷ effective life (100% ÷ 12 = 8.33%).
Worked Example: $6,000 Commercial Oven
Purchase a commercial oven for $6,000 on 1 July 2025 (start of the financial year) for a full-year deduction:

Which method is better? Diminishing value gives you $1,000 in Year 1 vs $500 with prime cost. Most small businesses prefer diminishing value for the bigger upfront deduction.
First-Year Pro-Rata Rule
If you purchase the commercial oven partway through the financial year, your first-year deduction is pro-rated based on the number of days you held the asset.
Example: Buy a commercial oven for $6,000 on 1 January 2026 (181 days remaining in the FY).
- Diminishing value: $6,000 × 16.67% × (181/365) = $496
- Prime cost: $6,000 × 8.33% × (181/365) = $248
Instant Asset Write-Off
If your commercial oven costs less than the instant asset write-off threshold ($20,000 for the 2024–25 income year), you may be able to deduct the entire cost immediately rather than depreciating over 12 years. This applies to small businesses with aggregated turnover under $10 million.
Always check the current ATO guidance as thresholds can change each financial year.
What Counts as “Commercial Ovens” for ATO Purposes?
The ATO’s 12-year effective life applies to:
- Convection ovens
- Combi ovens
- Pizza ovens
- Deck ovens
- Commercial ranges with built-in ovens
Commercial fridges share the same 12-year effective life. Dishwashers have a 7-year effective life.
How to Claim Depreciation
- Must be used for business purposes. Only claim the business-use percentage. If you use the commercial oven 70% for work, claim 70% of the depreciation.
- Choose your method — diminishing value or prime cost. You must stick with the same method for the life of that asset.
- Keep records — purchase receipt, proof of business use percentage, and your depreciation schedule.
- Report in your tax return — include the deduction amount in your business expenses or work-related deductions.

Frequently Asked Questions
What is the ATO effective life for commercial ovens?
The ATO sets the effective life at 12 years for commercial ovens.
Should I use diminishing value or prime cost?
Most small businesses use diminishing value because it gives a bigger deduction in the first year ($1,000 vs $500 on a $6,000 commercial oven).
Can I claim the full cost as an immediate deduction?
If the commercial oven costs less than the instant asset write-off threshold and you are an eligible small business, yes — you can deduct the full cost in the year of purchase. If you also use it personally, only claim the business-use percentage.
What if I sell or dispose of the commercial oven before it’s fully depreciated?
You’ll need to do a balancing adjustment. If you sell it for more than the written-down value, the difference is assessable income. If you sell for less, you can claim the remaining amount as a deduction.
