How much did your KitchenAid mixer actually cost you last year? Not what you paid for it — what it cost you to use it. Every batch of dough, every pound of butter creamed, every hour it ran brought that machine one step closer to the day it breaks down and needs replacing. That replacement cost doesn't appear on any receipt, so most makers never think about it. But it's real, it's significant, and it's almost certainly missing from your product pricing.
This is equipment depreciation — the gradual loss of value your tools experience over their useful life. Ignore it, and you're subsidizing every product you sell with money you'll need later. Account for it, and you unlock more accurate pricing, legitimate tax deductions, and the ability to plan equipment replacements before they become emergencies.
What Depreciation Actually Means (In Plain English)
Depreciation isn't an accounting trick. It's a simple idea: expensive equipment doesn't last forever, so you should spread its cost across the years you use it.
Say you buy a $2,000 convection oven for your home bakery. You expect it to last 7 years, at which point it'll be worth maybe $200 as a trade-in. That means you're consuming $1,800 of value over 7 years — roughly $257 per year, or about $21 per month.
That $21/month is a real cost of doing business, even though you're not writing a check for it. If you bake 200 items per month, depreciation adds about $0.11 to the cost of every single product. Doesn't sound like much — until you realize you have an oven, a mixer, baking sheets, a food processor, packaging equipment, and maybe a display setup. Suddenly you're looking at $0.40-0.80 per item in equipment costs you never accounted for.
Why Most Small Makers Skip It (And Why That's a Problem)
The honest answer: depreciation sounds like something only accountants care about. When you're running a small craft business, you're focused on materials, time, and sales — not abstract accounting concepts.
But skipping depreciation creates three concrete problems:
1. Your prices are too low. If your product costs $4.00 in materials and $3.00 in labor, you might price it at $12.00 thinking you have a healthy margin. But if equipment depreciation adds $0.60 per item and you're making 500 items a month, that's $300/month in costs you're absorbing without realizing it. Over a year, that's $3,600 straight out of your profit.
2. You're missing tax deductions. The IRS allows small businesses to deduct depreciation on business equipment. For many makers, this is one of the largest deductions available — and one of the most commonly missed. We'll cover the specific methods below, but the short version is: if you bought equipment for your business and you're not depreciating it, you're likely paying more in taxes than you need to.
3. Equipment failures blindside you. Without tracking depreciation, you have no system for knowing when equipment is approaching end-of-life. The replacement comes as a financial shock instead of a planned expense. Makers who track depreciation build replacement funds gradually — $50/month set aside is a lot less painful than a surprise $3,500 bill.
The Three Depreciation Methods You Need to Know
You don't need an accounting degree. For small maker businesses, three methods cover virtually every scenario.
Straight-Line Depreciation
The simplest and most common method. You spread the cost evenly across the equipment's useful life.
Formula:
Annual Depreciation = (Purchase Price - Salvage Value) ÷ Useful Life in Years
| Equipment | Purchase Price | Salvage Value | Useful Life | Annual Depreciation | Monthly Cost |
|---|---|---|---|---|---|
| Stand mixer | $500 | $50 | 10 years | $45.00 | $3.75 |
| Convection oven | $2,000 | $200 | 7 years | $257.14 | $21.43 |
| Pottery kiln | $3,500 | $300 | 15 years | $213.33 | $17.78 |
| 3D printer | $1,200 | $100 | 5 years | $220.00 | $18.33 |
| Sewing machine | $800 | $75 | 12 years | $60.42 | $5.03 |
| Heat press | $400 | $25 | 6 years | $62.50 | $5.21 |
Best for: Most small maker equipment. It's predictable, easy to calculate, and generally accepted for tax purposes.
Declining Balance Depreciation
This method front-loads the depreciation — you deduct more in the early years and less later. It reflects reality for equipment that loses value quickly (like technology).
The most common version is double declining balance, which depreciates at twice the straight-line rate each year, applied to the remaining book value.
Example: A $1,200 3D printer with a 5-year life.
| Year | Book Value (Start) | Depreciation (40%) | Book Value (End) |
|---|---|---|---|
| 1 | $1,200.00 | $480.00 | $720.00 |
| 2 | $720.00 | $288.00 | $432.00 |
| 3 | $432.00 | $172.80 | $259.20 |
| 4 | $259.20 | $103.68 | $155.52 |
| 5 | $155.52 | $55.52 | $100.00 |
Best for: Technology-heavy equipment (3D printers, laser cutters, CNC machines) that loses value or becomes obsolete faster in early years.
Section 179 / Bonus Depreciation
This is the one most small makers should know about but don't. Section 179 lets you deduct the full purchase price of qualifying equipment in the year you buy it, rather than spreading it over multiple years.
For 2026, the Section 179 deduction limit is well over $1 million — far more than any small maker will spend. Practically speaking, if you buy a $3,000 kiln for your pottery business, you can deduct the entire $3,000 on this year's taxes.
The catch: You need enough business income to offset the deduction, and the equipment must be used for business more than 50% of the time. Talk to a tax professional about whether Section 179 makes sense for your specific situation.
Best for: Years when you make significant equipment purchases and have enough income to absorb the deduction.
How to Calculate Your Per-Product Equipment Cost
This is where depreciation becomes directly actionable for pricing. Here's the process:
Step 1: List all your business equipment with purchase price, estimated salvage value, and useful life.
Step 2: Calculate annual depreciation for each piece using straight-line (or your preferred method).
Step 3: Sum the total annual depreciation across all equipment.
Step 4: Divide by your annual production volume.
Example for a home bakery:
| Equipment | Annual Depreciation |
|---|---|
| Stand mixer | $45.00 |
| Convection oven | $257.14 |
| Food processor | $35.00 |
| Sheet pans & bakeware | $40.00 |
| Packaging sealer | $28.00 |
| Display equipment | $50.00 |
| Total | $455.14 |
If you produce 4,800 items per year (about 400/month):
$455.14 ÷ 4,800 = $0.095 per item
Nearly ten cents per item. Across a year of production, that's $455 your prices need to cover — and that's for a relatively modest equipment setup. Makers with kilns, commercial ovens, or CNC machines often see per-item equipment costs of $0.30-0.50 or more.
Setting Up a Replacement Fund
Knowing your depreciation numbers unlocks one of the best financial habits a small business can develop: a planned replacement fund.
Take your total annual depreciation ($455 in our bakery example) and set aside that amount each year — about $38/month — in a separate savings account. When your oven dies in year 6 or your mixer gives out in year 9, the money is already there. No emergency. No scrambling. No putting a replacement on a credit card.
Some makers go a step further and adjust for inflation. If you expect equipment costs to rise 3-4% per year, add that percentage to your monthly set-aside. Your future self will thank you.
Tracking It Without Losing Your Mind
You could manage depreciation in a spreadsheet, but it gets unwieldy fast — especially when you're tracking multiple pieces of equipment with different purchase dates, useful lives, and methods.
Ardent Seller handles this automatically. When you add equipment to your inventory, you enter the purchase price, salvage value, useful life, and depreciation method. The system calculates current book value, monthly depreciation, and per-product cost allocations in real time. It also tracks maintenance history and flags equipment approaching end-of-life, so replacement planning is built into your normal workflow rather than a separate task you forget about.
Whether you use dedicated software or a spreadsheet, the important thing is that you're tracking it at all. Even a rough estimate is infinitely better than ignoring equipment costs entirely.
Common Questions
Do I depreciate equipment I already owned before starting my business? Yes, but you use the fair market value at the time you started using it for business — not what you originally paid. If you bought a $500 mixer three years ago for personal use and now use it for your bakery, its current fair market value might be $300. That's your starting basis for depreciation.
What about equipment I use for both personal and business purposes? You can only depreciate the business-use percentage. If you use your oven 60% for business and 40% for personal cooking, you depreciate 60% of the cost. Keep a usage log to support your deduction if you're ever audited.
Should I depreciate small tools and supplies? Generally, items under $200-300 are better expensed immediately (deducted in full the year you buy them) rather than depreciated over time. The IRS de minimis safe harbor allows businesses to expense items up to $2,500 per item. Spatulas, measuring cups, and hand tools — just expense them. Depreciation is for the big stuff.
What's a reasonable useful life for my equipment? The IRS publishes guidelines, but for small maker equipment, these are reasonable estimates:
| Equipment Type | Useful Life |
|---|---|
| Major appliances (ovens, kilns) | 7-15 years |
| Power tools & machinery | 5-10 years |
| Technology (3D printers, computers) | 3-5 years |
| Hand tools & small equipment | 3-7 years |
| Vehicles | 5-7 years |
| Furniture & displays | 7-10 years |
The Bottom Line
Equipment depreciation isn't glamorous, and it'll never be the reason you got into making things. But it's the difference between knowing what your products actually cost and guessing. It's the difference between a surprise $3,000 expense and a planned replacement. And it's the difference between paying the right amount of taxes and overpaying because you didn't know you had a deduction.
Start simple. List your equipment. Pick straight-line depreciation. Calculate the per-item cost. Fold it into your pricing. Set up a replacement fund. You can refine the details later — the important thing is getting the numbers on paper so they stop being invisible.
Your products are worth what they cost to make, and your equipment is part of that cost. Price accordingly.
