How to Calculate COGS for Your Handmade Business

Cost of goods sold — COGS — is one of those accounting terms that sounds intimidating but is actually the most useful number in your handmade business. It tells you what it really costs to make the things you sell, which means it tells you whether you're making money. This guide explains COGS in plain language and shows you how to calculate it.

What COGS actually means

COGS is the direct cost of producing the goods you sold in a period. For a handmade shop, that's mainly the materials and the direct labor that went into the products customers bought.

It does not include the general costs of running your business — advertising, your website subscription, the time you spend answering messages. Those are operating expenses. The line is simple: if the cost was needed to physically make a sold product, it's COGS; if it was needed to run the business in general, it's an operating expense.

Your gross profit is Revenue − COGS. That single subtraction is the clearest signal of whether your products are priced right.

The three components of handmade COGS

1. Materials

Every physical input consumed making the products you sold: wax, fabric, beads, oils, jars, packaging, labels. The key word is consumed — COGS is about what went into sold items, not everything you bought. If you bought 10 kg of wax but only used 4 kg in sold candles this month, only the 4 kg belongs in this period's COGS (the rest is still inventory).

2. Direct labor

If you pay yourself or someone else to actually make the product, that labor is part of COGS. Many solo makers leave this out because they don't cut themselves a paycheck — but ignoring it hides your true cost and makes a barely-profitable product look healthy.

3. Direct overhead (optional but smart)

Some makers also allocate a small share of production-specific overhead (equipment, a portion of studio costs) into COGS. For a small shop, materials and labor are the big two; add overhead once those are solid.

The basic COGS formula

Over an accounting period, the standard formula is:

COGS = Beginning inventory + Purchases − Ending inventory

In other words: what you started with, plus what you bought, minus what's left tells you what was used. For a handmade shop tracking finished products and materials, you can also build COGS bottom-up from each sold item's recipe cost — which is more precise and more useful day to day.

Per-product COGS: the version that helps you decide

The period formula is what your accountant wants at tax time. But the version that helps you run the shop is per-unit COGS: the material + labor + overhead cost baked into one finished product.

For our earlier candle example: $5.30 materials + $2.00 labor + $1.00 overhead = $8.30 unit COGS. If you sell it for $16.99, your gross profit per unit is $8.69, a margin of about 51%.

Knowing per-unit COGS lets you answer the questions that actually matter: Which products are most profitable? Which are barely breaking even? Which need a price increase?

The hardest part: keeping material costs current

The reason COGS is hard for makers isn't the formula — it's that material prices keep changing. You buy fragrance at one price in January and a higher price in March. Which cost belongs in the candle you made in April?

The cleanest method is weighted-average cost: every time you buy more of a material, the system blends the new price with the old stock to give one current average cost. That average then flows into every recipe automatically. Doing this by hand in a spreadsheet is tedious and error-prone, which is why most makers' COGS numbers are out of date.

A tool like Mavenory maintains weighted-average material costs for you: you log a purchase, and every recipe that uses that material — and therefore every product's COGS — updates instantly. No manual recalculation, no stale numbers.

Why accurate COGS pays off

Three concrete benefits: you price correctly (because you know your real floor), you spot unprofitable products early (before they eat a season's profit), and you have clean numbers at tax time (gross profit is just revenue minus COGS).

The takeaway

COGS is simply the direct cost of what you sold — materials plus direct labor, optionally a slice of overhead. Track it per product and keep material costs current, and you turn a scary accounting term into your sharpest decision-making tool.
