Pour cost is the percentage of your liquor revenue that goes toward the liquor itself. The formula is simple: divide the cost of liquor used during a period by the liquor revenue for that same period. If you used $3,000 worth of liquor and brought in $15,000 in liquor sales, your pour cost is 20%. A well-run bar typically falls between 18% and 24%, depending on your drink mix and pricing strategy.

The important word in that formula is “used,” not “purchased.” You need beginning and ending inventory counts to calculate what was actually consumed. Take the beginning inventory value, add purchases during the period, then subtract the ending inventory value. That gives you cost of liquor used. Most bars should do this weekly or biweekly. Monthly is the bare minimum, but waiting that long means a problem could drain profits for weeks before you catch it.

Once you have your actual cost of liquor used, compare it to what your POS system says you sold. Your POS tracks every drink rung up, so you can calculate what your theoretical liquor cost should have been based on recipes and pricing. The gap between theoretical cost and actual cost is your variance. Anything under 3% is normal and accounts for spillage, minor measurement differences, and the occasional broken bottle. When you’re consistently running above 3-5%, something needs attention.

The usual suspects behind high variance are overpouring, unrecorded comps, incorrect ring-ups (bartender rings a well drink but pours premium), theft, and simple waste. You won’t know which one it is from the numbers alone, but the numbers tell you where to look. If your spirits pour cost is way off while beer and wine are fine, the problem is at the bar during service, not in receiving or storage.

This is where your bookkeeping setup matters. If your books lump all alcohol purchases into one account, you can’t break pour cost down by category. Your overall pour cost might look acceptable at 22% while spirits are quietly running at 30%. Set up your chart of accounts to separate liquor, beer, and wine at minimum. Track purchases by category and count inventory by category. That level of detail is what turns pour cost from a rough gauge into a real management tool.

Restaurants and bars lose more money from sloppy inventory tracking than most owners realize. A few percentage points of variance on a bar doing $30,000 a month in liquor sales adds up to thousands of dollars walking out the door every year. The math is not complicated, but it requires consistent counts, clean purchase records, and accurate POS data.

If your books are behind or your categories are a mess, start by getting the financial side organized so the inventory tracking actually works. Bookkeepers in Orlando who understand food and beverage operations can set up your accounts to support pour cost analysis from day one, rather than forcing you to guess where the money is going. Once the structure is right, running these numbers becomes a weekly habit instead of a frustrating guessing game.
