What is Sales Mix?
Sales mix is the share of your total sales that each menu item or category makes up, measured in units sold or in revenue.
It answers a simple question: of everything you sold, how much was each thing? Your POS usually calls this the product mix report, or PMIX.
The Formula
Item Sales ÷ Total Sales = Sales Mix %
You can run it two ways, and they give different answers:
Unit mix: items sold ÷ total items sold
Revenue mix: item revenue ÷ total revenue
Quick Example
One week at the bar:
| Item | Sold | Price | Revenue | Unit Mix | Revenue Mix |
|---|---|---|---|---|---|
| Draft Beer | 300 | $7 | $2,100 | 42.9% | 30.8% |
| Margarita | 200 | $11 | $2,200 | 28.6% | 32.3% |
| Old Fashioned | 120 | $13 | $1,560 | 17.1% | 22.9% |
| Spritz | 80 | $12 | $960 | 11.4% | 14.1% |
| Total | 700 | — | $6,820 | 100% | 100% |
Beer is 43% of what you poured but only 31% of what you brought in. Both numbers are true; they answer different questions.
Unit Mix vs Revenue Mix
Pick the one that matches the question:
Revenue mix for weighting percentages, like Weighted Pour Cost. A drink's pour cost is a share of its price, so it should be weighted by its share of revenue.
Unit mix for weighting per-drink numbers, like average Contribution Margin, and for inventory, pars, and prep. Your bar goes through bottles one pour at a time, not one dollar at a time.
Using the wrong one won't throw an error. It just quietly gives you the wrong number.
How Sales Mix Moves Your Numbers
Say those four drinks run these pour costs: Old Fashioned 20%, Margarita 30%, Spritz 22%, Draft Beer 25%. Weighted by revenue mix, the bar runs a 25.1% pour cost.
Next week, a margarita special shifts 100 sales from beer to margaritas. No recipe or price changed. Here's what moved:
Weighted pour cost: 25.1% → 25.8%
Revenue: $6,820 → $7,220
Total contribution margin: $5,112 → $5,357 (+$245)
Pour cost went up, and the bar made more money. That's the point: a pour cost that rises because of mix isn't the same problem as one that rises because of overpouring or price increases. Sales mix is how you tell them apart.
Why It Matters
It drives your Weighted Pour Cost. Same recipes, different mix, different number.
It shows what your guests actually order, not what you think they order.
It sets your Par Levels and prep. The items that sell most need the most stock and the most batched components.
It's the popularity side of menu engineering. Paired with contribution margin, it shows which drinks to feature, reprice, or cut.
Common Mistakes
Using the wrong kind of mix Weighting pour cost by units instead of revenue overweights cheap drinks and skews the result.
Reading one week as the trend A private event, a game night, or a snowstorm can swing a week's mix. Compare the same periods over time.
Lumping categories together Beer, wine, and cocktails behave differently. A cocktail-only mix tells you far more about your cocktail menu.
Messy POS buttons If "Margarita," "Spicy Marg," and "Marg - HH" are three buttons, combine them before you read the mix. Otherwise your top seller looks like three middling ones.
Mixing in happy hour without noticing The same drink at two prices has two different pour costs. Split happy hour sales out, or your numbers blur.
Sales Mix vs Weighted Pour Cost
Sales mix = what share of sales each item makes up
Weighted pour cost = your overall pour cost, using that mix as the weights
Sales mix is an input. Weighted pour cost is one of the results.
FAQ
Is sales mix the same as product mix? Yes. Most POS systems call the report "product mix" or "PMIX." Same thing.
How often should I check my sales mix? Weekly is enough for most bars. Compare it to the same week last month or last year, not just last week, and always after a menu change.
Can I change my sales mix? Yes. Menu placement, names, pricing, and what your staff recommends all move it. See Using Menu Engineering To Increase Revenue.
Should I track sales mix by item or by category? Both. Category mix (beer, wine, spirits, cocktails) shows where your revenue comes from. Item mix shows which drinks carry each category.
Do This in Spec
Spec keeps an up-to-date cost and menu price for every drink. Pair that with your POS product mix report and you have everything you need for weighted pour cost and contribution margin, without rebuilding a spreadsheet every week.

Bottom Line
Sales mix is the bridge between individual drinks and your bar's overall numbers. When pour cost or margins move, check the mix before you assume something went wrong.
