One of the biggest mistakes makers make isn't charging too little. It's not knowing what their products actually cost to make.
Whether you sell on Etsy, Shopify, at craft fairs, through your own website, or on social media, every profitable product starts with accurate costs. If you're guessing, you may be leaving money on the table without realizing it.
The good news is that you don't need complicated accounting to get started.
Imagine selling a product for $35.
It feels like a great sale. But after materials, packaging, marketplace fees, shipping supplies, and the time you spent making it, you discover that you earned only $4.
Without tracking your costs, it's easy to mistake revenue for profit.
Knowing your costs helps you:
- Set prices that leave room for profit
- Identify products that aren't worth making
- Make smarter purchasing decisions
- Grow your business with confidence
1. Track Every Material
This is the obvious place to start, but material costs are often incomplete.
Don't count only the largest or most expensive pieces. Include everything that becomes part of the finished product, such as:
- Wood
- Resin
- Fabric
- Leather
- Filament
- Acrylic
- Paint
- Hardware
- Glue
Calculate the amount used for one product rather than assigning the cost of an entire package to a single item. If a $24 sheet of plywood makes eight signs, the plywood cost is $3 per sign.
Even inexpensive materials add up across dozens or hundreds of orders.
2. Count Consumables
Consumables are supplies used during production that don't necessarily become part of the finished product. Because customers rarely see them, they're easy to overlook.
Examples include:
- Sandpaper
- Masking tape
- Painter's tape
- Laser masking
- CNC bits
- Printer nozzles
- Cleaning supplies
- Paper towels
- Shop rags
You may use only a few cents' worth each time. Across hundreds of products, however, those pennies become real money.
You don't need to measure every strip of tape. A reasonable per-product estimate is far more useful than treating the cost as zero.
3. Include Packaging
Customers don't receive only your product. They receive an experience, and the packaging that creates that experience has a cost.
Remember to include items such as:
- Shipping boxes
- Bubble wrap
- Tissue paper
- Packing paper
- Labels
- Stickers
- Thank-you cards
- Tape
These small items can add several dollars to every order. If they're missing from your calculation, your expected profit will look better than the profit you actually earn.
4. Keep Supplier Prices Current
Material prices change constantly. Plywood gets more expensive, filament goes on sale, and shipping costs increase.
If you haven't updated your material costs in six months, your product pricing may already be out of date. A product that was comfortably profitable last season could be underpriced today.
Set a reminder to review important supplier prices every month or two. Prioritize the materials you use most often and the products that generate the most sales.
5. Review Your Costs Monthly
Your business changes too. You find new suppliers, introduce new products, change your packaging, and sell through marketplaces with different fees.
Take 15–30 minutes once a month to review:
- Frequently used material prices
- Packaging and shipping supplies
- Marketplace and payment-processing fees
- The time required to make your best-selling products
- Products with unexpectedly low profit
Think of it as routine maintenance for your business. A short monthly review can prevent months of accidental underpricing.
If you're new to tracking costs, don't aim for perfection. Start with three numbers:
- Material cost
- Packaging cost
- Time spent making the item
Those three numbers alone will give you a much clearer picture than guessing.
For your time, choose an hourly rate and multiply it by the active time needed to make and package one item. If a product takes 30 minutes and your target rate is $24 per hour, its labor cost is $12.
As your business grows, you can add marketplace fees, shipping estimates, machine costs, and overhead. The goal is not to build a perfect system on day one. It's to replace guesses with useful information.
Many makers begin with a spreadsheet, and that's a fantastic place to start.
As your catalog grows, though, spreadsheets become harder to maintain. Material prices change, products share components, marketplace fees vary, and updating every formula manually takes time.
Maker Forge keeps that information connected in one place. You can:
- Track materials and reusable components
- Store packaging costs
- Calculate product costs automatically
- Estimate marketplace fees
- See expected profit before publishing a listing
- Update a material price once and have every affected product reflect the change
Instead of wondering whether a product is profitable, you'll know.
Successful makers know their numbers.
You don't need expensive software or an accounting degree to build a profitable business. Start by understanding what each product truly costs to make. Review those costs regularly, improve your estimates as you learn, and let the numbers guide your pricing decisions.
Once you know your costs, you can price with confidence—and that's the foundation of a sustainable maker business.
