As a bar owner or manager, you're buried in numbers. You track nightly sales, staff wages, supplier invoices, and utility bills. But there is one number that rises above all others in importance, one metric that defines the health and success of your entire beverage operation: Gross Profit (GP).

Here's the problem: most bar managers don't really know their GP. They know their sales, and they might have a target GP in their head (e.g., "we aim for 70%"). But they aren't accurately calculating their actual, achieved GP.

And if you aren't accurately calculating your Gross Profit, you aren't in control of your business. You're just guessing.

This guide will break down what your GP is, how to calculate it properly, what you should be aiming for, and how to fix it when it's not right.

What is Gross Profit, and Why Does it Matter More Than Sales?
Let's get this straight: Sales are vanity, GP is sanity.

You can have the busiest bar in Dublin, with sales through the roof, but if your GP is low, you could be making less money than the quiet pub down the street.

· Sales (Revenue): This is the total amount of money you take in at the tills. It's an impressive-sounding number, but it's not your profit.

· Gross Profit (GP): This is the money you have left over from your sales after you've paid for the products you sold (the kegs, the bottles, the wine).

This GP is the fund that pays for everything else: your rent, rates, staff wages, electricity, insurance, and—finally—your own net profit. If your GP is too low, you'll find yourself in a constant cash-flow struggle, no matter how busy you are.

The Simple Formula for an Accurate Bar GP Calculation
So, how do you calculate it? The formula is expressed as a percentage:

GP (\%) = \frac{\text{Total Revenue} - \text{Cost of Goods Sold (COGS)}}{\text{Total Revenue}} \times 100

Total Revenue is the easy part; that's your total "wet sales" from your POS system for the period (e.g., one month).

The difficult part, and the one most people get wrong, is the Cost of Goods Sold (COGS).

How to Actually Calculate Your Cost of Goods Sold (COGS)
Your COGS is not just the total of your supplier invoices for the month. That's a common, costly mistake. You might have bought €10,000 in stock, but you didn't sell all of it.

To find your true COGS, you must perform a physical stocktake.

The formula is:

COGS = Opening Stock Value + Purchases - Closing Stock Value

Let’s break that down:

Opening Stock Value: The monetary value of all the stock you had on-site (in the cellar, on the shelves, in the fridges) at the very start of the period.

Purchases: The total value of all beverage stock delivered and invoiced during the period.

Closing Stock Value: The monetary value of all the stock you have on-site at the very end of the period, based on a new, detailed physical stocktake.

Example:

· You start the month with €15,000 of stock (Opening Stock).

· You buy €10,000 of stock during the month (Purchases).

· You end the month with €13,000 of stock (Closing Stock).

Your COGS = €15,000 + €10,000 - €13,000 = €12,000

Your actual cost of the products you sold was €12,000.

Now, let's say your total wet sales (Revenue) for that month were €40,000.

Your GP = (€40,000 - €12,000) / €40,000 = 0.7

Your Gross Profit = 70%

This is the only way to get a true bar GP calculation. Without a physical stocktake at the start and end of the period, you are flying blind.

What is a "Good" Bar GP for an Irish Pub?
This is the golden question. The answer is "it depends," because not all products are created equal. You can't just have one GP target; you need a target for each category.

· Draught Beers & Ciders: These have the highest cost and therefore the lowest GP. You're typically aiming for 65% - 70%.

· Bottled Beers & Ciders: Similar to draught, the GP is lower. Aim for 68% - 73%.

· Wines (by the Glass): These should be a good earner. You're aiming for 70% - 75% or more, depending on your pricing.

· Spirits: This is your profit engine. With 19.7 measures in a 700ml bottle, your GP on spirits should be very high: 80% - 85%.

· Soft Drinks (Draught): This is often your highest GP category, potentially 85% - 95%.

Your overall "blended" GP will be an average of all these, weighted by what you sell the most of. For a typical wet-led pub, a healthy blended GP is between 70% and 75%. If you're below 70%, you have a leak.

The 5 "GP Killers" Hiding in Your Business
If you've done the bar GP calculation and your number is lower than the target, it's almost certainly due to one of these five "GP Killers":

Supplier Price Creep: Your supplier invoices go up by 3-5%, but your menu prices stay the same. This silently shaves your margin off every single drink you sell.

Inaccurate Pouring & Waste: Every over-poured spirit, every pint with a 2-inch head, and every unlogged spillage is stock you paid for but didn't get revenue for. It's a direct attack on your GP.

Poor Product Mix: You're pushing too many low-margin products. For example, if all your promotions are for bottled beers (low GP) and you're not upselling spirits (high GP), your overall blended GP will suffer.

Staff Theft & Unauthorised Comps: (Linked to Article 2) A "free" drink for a friend isn't free. It's a 100% loss, and it devastates your GP.

Flawed Pricing Strategy: Setting your prices based on what the pub down the road charges. You must set your prices based on your cost and your target GP for that specific product.

How to Protect and Improve Your Gross Profit
You cannot manage what you do not measure. A regular, professional beverage stocktake is the only way to protect your GP.

A professional stocktaker doesn't just give you one blended GP number. They provide a detailed breakdown: a GP report for draught, for spirits, for wine, and even for individual product lines.

This is your diagnostic tool. You can instantly see, "My overall GP is 68%, but why? Ah, my spirits GP is only 70% when it should be 82%."

You've found the leak. Now you know you have an over-pouring, theft, or pricing problem specifically with your spirits. You can stop guessing and start fixing the right problem. A professional stocktaker will not only give you this data but will also provide the expert advice on how to fix it.

Stop guessing what your profit is. It's time to know it. An accurate bar GP calculation is the first step to a healthier, more profitable business. Contact Hospitality Partners today, and let's find out exactly what your achieved GP is and build a plan to improve it.
