Calculate the merchandise margin retained after markdowns and allowances. Follow a category example from original ticket value to net sales, merchandise cost and the reconciliation back to initial margin.
The maintained margin formula is net sales minus merchandise cost of the goods sold, divided by net sales. It measures the merchandise profit retained after markdowns and allowances. Use actual selling prices and the costs of the same sold units, rather than the original ticket value or the cost of everything purchased.
Maintained merchandise profit = Net sales − Merchandise cost of goods sold
Maintained margin = Maintained merchandise profit / Net sales
Net sales = Original ticket value of sold merchandise − Markdowns − Other selling-price allowances
Show the final ratio as a percentage. The last equation is a sales bridge for merchandise with no unit returns; returned units need their own sales and cost reversals.
Retail texts often call this selling-price measure maintained markup. McGraw Hill's retail pricing chapter calculates maintained markup by subtracting cost from the reduced selling price and dividing by that selling price. This article calls that measure maintained margin and states the cost boundary explicitly.
It is the realized merchandise version of gross profit margin. It does not establish operating profit: store payroll, rent, advertising and corporate costs still need to be covered. If your ledger includes buying or occupancy costs in gross profit, reconcile those separately before comparing the two measures.
The denominator matters. Profit divided by merchandise cost is markup on cost, which answers a different pricing question. Neither ratio becomes a net profit percentage merely because the merchandise has sold.
Export the sales lines for one closed month. Retain the transaction date, sale or credit identifier, SKU, category, quantity, original ticket value, markdown, other allowance, net sales and merchandise cost. Keep a description of the cost basis alongside the review.
For a distributor with retail counters, merchandise cost might include the supplier invoice and allocated inbound freight. Use the posted cost of the sold units. Supplier payments and purchase orders are poor substitutes because they can relate to inventory still on the shelf.
The IRS explanation of cost of goods sold distinguishes beginning inventory, purchases and ending inventory. That distinction supports the matching check here; this management review is not a replacement for your financial reporting or tax inventory policy.
Confirm whether exported sales already reflect markdowns. If they do, use that net sales column in the ratio. Retain the markdown column to explain the difference from ticket value, rather than subtracting it again.
Consider an illustrative US homewares distributor's retail counters for September 2026. There are no unit returns in these rows. Other allowances are coupons and partial price credits; all sales values exclude sales tax.
The input amounts are:
| Category | Original ticket value (USD) | Markdowns (USD) | Other allowances (USD) | Merchandise cost (USD) |
|---|---|---|---|---|
| Kitchen | 120,000 | 12,000 | 3,000 | 63,000 |
| Storage | 80,000 | 12,000 | 2,000 | 42,000 |
| Bath | 50,000 | 2,500 | 2,500 | 27,000 |
| Total | 250,000 | 26,500 | 7,500 | 132,000 |
Subtract both reductions to reach net sales, then subtract merchandise cost. Percentages below are rounded to two decimals; calculate with unrounded amounts.
| Category | Net sales calculation (USD) | Net sales (USD) | Merchandise profit (USD) | Maintained margin |
|---|---|---|---|---|
| Kitchen | 120,000 − 12,000 − 3,000 | 105,000 | 105,000 − 63,000 = 42,000 | 40.00% |
| Storage | 80,000 − 12,000 − 2,000 | 66,000 | 66,000 − 42,000 = 24,000 | 36.36% |
| Bath | 50,000 − 2,500 − 2,500 | 45,000 | 45,000 − 27,000 = 18,000 | 40.00% |
| Total | 250,000 − 26,500 − 7,500 | 216,000 | 216,000 − 132,000 = 84,000 | 38.89% |
The total is $84,000 / $216,000 = 38.89%. Divide summed profit by summed sales. The University of Maine's pricing guidance likewise calculates the overall store percentage from total gross margin and total sales, allowing for different department margins.
For these same sold units, profit at original tickets would have been $250,000 − $132,000 = $118,000. The initial margin was $118,000 / $250,000 = 47.20%.
| Reconciliation step | Merchandise profit (USD) |
|---|---|
| Profit at original ticket value | 118,000 |
| Less markdowns | −26,500 |
| Less other allowances | −7,500 |
| Maintained merchandise profit | 84,000 |
That $84,000 must match the category profit total. Also check that net sales plus markdowns plus allowances equals ticket value: $216,000 + $26,500 + $7,500 = $250,000. Finally, the $216,000 sales and $132,000 merchandise cost must reconcile to the corresponding ledger lines or to an explained bridge.
The margin fell by 47.20% − 38.89% = 8.31 percentage points, using unrounded ratios before rounding. Do not divide the $34,000 of reductions by ticket value and call that the margin-point decline: the initial and maintained margins use different sales denominators.
Storage has the lowest maintained margin. Its reductions total $14,000 against $80,000 of ticket value, or 17.50%. Check the clearance lines and promotion approvals before changing the category's full-price strategy.
Suppose a revised promotion would recover $6,000 of selling price on the same units, with costs unchanged. Total net sales would become $222,000 and merchandise profit $90,000. The resulting maintained margin would be $90,000 / $222,000 = 40.54%.
That is a sensitivity, not a sales forecast. A higher selling price could reduce demand and leave additional inventory. Review the affected units and stock age before treating the possible margin improvement as an achievable result. The profit margin calculator helps distinguish this merchandise result from operating and net margins.
Bring a sales export with original tickets, reductions, net sales and matched merchandise costs; Covirage maps the columns, and its tools compute and check category margins while the external AI model explains the result with every figure traced to its rows.

Initial margin uses the original planned selling price. Maintained margin uses the actual net selling price after reductions. The difference shows how much the original pricing margin changed, but a fair comparison requires the same merchandise units and the same cost definition.
For the same sold units and unchanged merchandise cost, an additional dollar of markdown reduces merchandise profit by a dollar. The percentage effect differs because the markdown also reduces net sales, which is the denominator. Changing volume requires a separate calculation.
The merchandise measure used here excludes store payroll, rent and other operating expenses. A retailer may classify some costs differently in its reported gross profit. Document the boundary and reconcile the merchandise review to the ledger before comparing periods or businesses.
Reverse returned sales and apply the corresponding merchandise-cost reversal under your accounting policy. A partial price refund reduces net sales without necessarily reversing units. Keep damaged returned stock and inventory write-downs visible so the cost treatment does not disappear inside the sales adjustment.
