How to Calculate Pour Cost: The Formula Bar Managers Use

It is Sunday night, the variance sheet does not add up, and your GM wants answers by Monday morning. You need to know how to calculate pour cost, not sit through a lecture about it. Start here.

Pour cost is the percentage of a drink’s menu price that gets spent on the liquid inside the glass. That is it. Everything else below is either the formula, a worked example, or a fix for when the number is uglier than you want.

What is pour cost and why does it matter?

Pour cost tells you how much of every dollar a customer hands over is walking back out the door as product cost. If your pour cost is 22%, you are keeping 78 cents on the dollar in gross margin before labor, rent, and the rest of the overhead pile.

Get pour cost wrong and every other number on the P&L bends with it. Labor percentages look worse because the denominator is smaller. Prime cost creeps. Owners start asking questions you do not want to answer on a Sunday night.

Most bar operators run inside an 18% to 24% overall beverage cost window. Spirits tend to land between 18% and 20%, draft beer around 20%, bottled beer near 25%, and wine anywhere from 30% to 40% depending on the list. Those ranges come from Backbar’s liquor cost guide and line up with the Sculpture Hospitality benchmark data citing Restaurants Canada. Want the full breakdown by category? See our guide to what a good pour cost percentage looks like.

What is the pour cost formula?

Here is the whole thing. One line. Memorize it.

Pour Cost % = (Liquor Cost ÷ Menu Price) × 100

That is the formula for a single drink. When you run it across a whole bar for a period, swap “liquor cost” for your total cost of goods sold over that period and “menu price” for total beverage sales. Same math, bigger numbers.

Worked example: a vodka soda

Let’s price out a standard vodka soda using Tito’s. You need three inputs:

1. Bottle cost
2. Bottle size in ounces
3. Pour size

Say you pay roughly $20 wholesale for a 750ml bottle of Tito’s. Wholesale prices shift by state and distributor, so use your invoice, not this number. A 750ml bottle holds 25.36 ounces. Your pour is 1.5 ounces.

Cost per ounce: $20 ÷ 25.36 = $0.789 Cost per 1.5oz pour: $0.789 × 1.5 = $1.18 Menu price: $9.00 Pour cost: ($1.18 ÷ $9.00) × 100 = 13.1%

That is a good-looking number on a simple spirit and soda. But most of your bar does not sell pure spirit. It sells cocktails. Here is where the math gets honest.

Worked example: a vodka cocktail with modifiers

Same Tito’s pour, but now it is a cosmo. Add cranberry juice, triple sec, fresh lime. The figures below are illustrative. Plug in your own invoice prices to get a real number for your bar.

Ingredient	Cost per pour
Tito’s, 1.5oz	$1.18
Triple sec, 0.5oz ($12 bottle)	$0.24
Cranberry, 1oz (from $4 half gallon)	$0.06
Fresh lime, 0.5oz (from $0.50 lime)	$0.15
Garnish and waste allowance	$0.10
Total liquor cost	$1.73

Menu price: $11.00. Pour cost: ($1.73 ÷ $11.00) × 100 = 15.7%.

Now run that math across every drink on your menu, weight each one by how often it sells, and you have your true blended pour cost. The reason most bar managers do not do this by hand is because it takes forever. That is the entire value proposition of a pour cost calculator that already knows your price book.

What is a good pour cost percentage for a bar?

“Good” depends on category. A dive pushing domestic drafts and well shots should run leaner than a craft cocktail lounge using housemade shrubs and $60 amaros. Here are the benchmarks most operators target:

Category	Target pour cost	Notes
Well spirits	18-20%	High volume, low-cost rail
Call spirits	20-22%	Mid-tier brands, the bulk of most menus
Premium / top shelf	22-25%	Customers trade cost for brand
Draft beer	22-24%	Waste and foam matter more than you think
Bottled and canned beer	24-28%	Less margin, less spillage
BTG wine	28-32%	Narrower margins, glass by glass
Bottle wine list	30-40%	The classic high-cost, high-ticket category

Your blended target should land somewhere between 18% and 22% for most neighborhood bars. High-volume dives can go lower. Craft cocktail rooms can profitably run 24% to 26% because their ticket averages and check spends are higher. Do not copy a number off a blog post and call it your goal. Set the target against your own P&L.

Why is my pour cost higher than it should be?

When the number on Monday morning looks wrong, it is almost always one of these five.

1. Free-pouring. A bartender counting in their head is not a measuring device. Industry trainers and consultants have been making the same point for years: a free-pour on a busy night routinely lands a quarter to a half ounce over target. On a 1.5oz spec, that is a 15% to 30% overpour, and it is pure margin walking out the door in ice.

2. Untracked comps and spills. Every manager comp, buyback, broken bottle, and rejected drink is product you already paid for. If it is not logged, your variance report will blame the bartender instead of the process.

3. Spillage and waste. Draft beer is the worst offender. Bad tap temperature, dirty lines, and aggressive pours can easily push draft waste into the double digits before you count foam chased down the drip tray.

4. Outdated menu prices. Distributors raise prices a couple of times a year. If you are not updating your cost per ounce and your menu price in parallel, your pour cost is drifting upward quietly every quarter.

5. Shrinkage. Inventory disappearing between counts. Could be theft, could be over-pouring, could be a delivery that never got checked in. You cannot fix what you cannot see, which is why weekly variance matters more than monthly.

One more honest note. Every bar carries some variance. As a rough industry rule of thumb, a healthy operation lives inside about 2% variance between expected and actual usage, and anything north of 5% starts looking like a process problem. If you are running double digits, the issue is almost never a single bad bartender. It is the system around them.

How do I lower pour cost without raising menu prices?

Raising prices is the lazy fix. It works until your regulars stop showing up. Here are five fixes that do not touch the menu board.

1. Jiggers, not jigger-free. Put jiggers on the bar and actually use them. Your bartenders will grumble for a week. Then they will adjust, and your pour cost will usually drop two to four points. Biggest fix on the list, and it costs about $40 in jiggers.

2. Weekly variance reports. Not monthly. Weekly. You need to catch a spike while the week it happened is still fresh. Monthly variance reports tell you something went wrong three weeks after you could have stopped it. A simple bar inventory spreadsheet template is enough to start.

3. Pour training and test pours. Every new bartender does a blind pour test on shift one. Every three months, every bartender on staff does another one. If they are more than a quarter ounce off spec, they retrain. This is not punitive. It is quality control.

4. Menu engineering. Run a sales mix report and look at which drinks print money and which do not. Kill the low-margin losers. Feature the high-margin winners in the middle of the menu where eyes land. See our features page for how PourIQ surfaces this automatically.

5. Tenthing discipline. End-of-night counts should be to the tenth of a bottle, not whole bottles. Whole-bottle counts make variance impossible to spot. Tenthing turns inventory into something you can actually audit.

One bonus fix that does not get enough attention: ice discipline. Bartenders who underfill glasses with ice end up overpouring spirit to hit the right liquid line. A properly filled rocks glass with quality ice locks the pour in at 1.5 ounces and keeps the drink cold longer. Cheap half-melted ice forces the bartender to compensate with more liquid, and that compensation comes straight out of your margin.

How often should I check pour cost?

Two cadences. Run them both.

Weekly variance. Fast inventory count, fast sales report, fast variance calculation. This is your early warning system. It takes 30 to 45 minutes if your system is halfway organized. Anything that spikes more than 2% over the prior week gets investigated on Monday.

Monthly deep review. Full count, full P&L reconciliation, full category breakdown. This is where you look at category mix, pricing drift, and trends across the quarter. You are not firefighting here. You are steering.

Owners who only check monthly are flying blind for three weeks at a time. Weekly variance is the difference between catching a problem and eating it.

A useful rule of thumb: if your weekly variance swings more than 2% in either direction, stop what you are doing and investigate. Two percent on a $30,000 weekly beverage sales number is $600 walking out the door. Miss that for a month and you are down $2,400 before anyone notices.

What tools track pour cost automatically?

You can do all of this in a spreadsheet. Plenty of bar managers do. But the spreadsheet does not flag variance spikes at 2am on a Saturday, it does not update when your distributor changes the Tito’s price, and it does not know which bartender was on shift when the shrinkage happened.

That is what inventory software is for. The category has a wide price range. MarketMan and Bar-i sit at the top end, roughly $200 to $450 per month, with deep feature sets aimed at multi-unit operators. Backbar lives in the middle. Partender and Bevager round out the space.

PourIQ was built to cover the same feature depth at a flat $75 per month with no hardware required. Weekly variance reports, tenthing support, recipe costing, menu engineering, and category-level pour cost tracking all ship in the base plan. See the full feature list or check pricing.

If you just want to run the numbers on a napkin version of this article, use the PourIQ pour cost calculator. Plug in bottle cost, pour size, and menu price, and it gives you the answer in seconds.

Run the math, then fix the problem

Pour cost is not a once-a-quarter number. It is a daily operating metric that tells you whether the bar is making money or leaking it. Calculate it weekly, benchmark it against the table above, and when it drifts, work the five fixes before you touch menu prices.
