Boutique COGS Calculator

Why COGS isn't the same as what you spent on inventory

This is the trip-up that quietly wrecks a boutique's profit number. You place a $12,000 wholesale order in March and, understandably, treat $12,000 as March's cost. But if $5,000 of that order is still hanging on the rack on March 31, it hasn't cost you anything yet — it is an asset sitting in your stockroom, not an expense. Your COGS for March is the merchandise that actually walked out the door.

Cash flow and profit are two different stories, and the inventory figures are what separate them. Spending is a cash event that hits your bank account the day the invoice clears. COGS is an accounting match between the cost of an item and the sale of that same item. A boutique can have a wildly profitable month on paper and a terrifying bank balance, or the reverse, purely because of when inventory was bought versus when it sold.

What belongs in cost of goods sold

The rule of thumb: if the cost exists because you acquired the merchandise, it's COGS. Wholesale unit cost, inbound freight, duties and customs, and inbound handling all qualify. If the cost exists because you're running a business — the Shopify plan, ads, the photographer, packaging and outbound shipping, payment processing, rent, payroll, your own pay — it's an operating expense and lives below the gross-margin line.

The two most commonly misfiled items are shipping and processing fees. Inbound shipping is COGS; outbound shipping is a selling expense. Payment processing is never COGS, even though it scales with sales. If you want the fully loaded per-unit number including freight and duties before you set a retail price, run the landed cost calculator first and use its result as your unit cost.

Reading your COGS percentage

COGS as a share of net sales is the mirror image of gross margin: 45% COGS means a 55% gross margin. Most apparel boutiques sit somewhere in the 40–60% COGS band, but the benchmark matters far less than the trend. Compare this period to the last three. If the percentage is drifting up while your pricing hasn't changed, the usual culprits are markdown depth, freight increases that never got passed into retail prices, or a vendor whose costs crept while your price tags stayed put.

Once you have COGS, the two questions worth asking next are how fast the inventory is moving and how hard the money tied up in it is working. Those are the inventory turnover calculator and the GMROI calculator, both of which take the COGS figure above as their starting input.
