What should be included in COGS?
COGS includes all direct costs- raw ingredients, packaging, and supplies used in each menu item. Labor, rent, utilities, and marketing are not part of COGS.
COGS Analysis for Quick Service Restaurants
Overview
In a quick service restaurant, it's easy to focus on serving customers fast and keeping them happy. But behind the scenes, one number can make or break your profits - your Cost of Goods Sold (COGS). This is the total cost of the food, packaging, and other ingredients you use to make every order. Think of it as the "price tag" on your menu items before you even sell them.
For many QSR owners, keeping COGS under control is a constant challenge. Ingredient prices go up and down, food sometimes gets wasted, and portions aren't always consistent. Even small changes can have a big impact - according to industry research, lowering food waste by just 2% can increase profits by as much as 4%. That's money you could be putting back into your business.
This is where COGS analysis comes in. By looking closely at what you're spending on each menu item compared to what you're selling it for, you can spot where costs are creeping up and take action before they eat away at your profits. It's not about complicated accounting - it's about understanding your numbers so you can make smarter, faster decisions every day.
The Components of COGS
Before you can control your COGS, you need to know exactly what's included in it. For a quick service restaurant, COGS covers all the direct costs of making and serving your menu items. This means the raw ingredients - meat, vegetables, sauces, seasonings - as well as packaging materials like cups, lids, wrappers, and takeaway boxes. If it's used up every time you make a sale, it's part of your COGS.
What's not included? Things like staff wages, rent, electricity, marketing, and equipment repairs. These are still important business costs, but they fall under different expense categories. Mixing them in with COGS can make it harder to see the true cost of your food.
The basic formula for COGS is -
COGS = Starting Inventory + Purchases During the Period - Ending Inventory
For example, if you start the week with $5,000 worth of food, buy another $2,000 in supplies, and end the week with $4,000 in stock, your COGS is $3,000.
Breaking COGS down into smaller parts is where the real insights come from. For instance, if chicken accounts for 35% of your total food cost, a sudden price increase or portion-size issue can push your overall COGS higher. By tracking each category separately - meat, produce, dairy, dry goods, beverages - you can spot exactly where costs are rising.
Understanding these components also helps when you're pricing your menu. If you know a burger costs you $2.50 to make, you can set a price that covers not only the food cost but also contributes to your overall profit. This clarity is the first step toward better control and bigger margins.
Gathering Accurate Data for COGS Analysis
A COGS analysis is only useful if the numbers you're working with are correct. Even small mistakes in your data can lead to wrong conclusions and poor business decisions. To get reliable results, follow these four key steps -
1. Count Your Inventory Regularly
Do a full inventory at least once a week, always using the same method. Count every item - from the boxes of fries in your freezer to the sleeves of cups in your storage room. Use consistent units (weight, volume, or pieces) so your measurements stay accurate over time.
2. Track All Purchases Accurately
Record every delivery and supplier invoice as soon as you receive it. Ingredient prices can change quickly, and using outdated costs will make your COGS calculation inaccurate. Keep your records organized so nothing slips through the cracks.
3. Keep Sales Data Clean
Your POS system should give you detailed sales numbers for each menu item. Clean, accurate sales data lets you compare what you're selling to how much you're using, helping you catch waste, theft, or over-portioning.
4. Avoid Common Mistakes
Don't double-count stock, skip "small" items like sauces or napkins, or rely on guesses instead of actual counts. These errors add up and make your analysis less reliable.
When your data is complete and correct, your COGS analysis becomes a clear roadmap - showing exactly where your money is going and where you can save.
Analyzing Trends and Identifying Problem Areas
Once you have accurate data, the next step is to look for patterns in your COGS over time. This isn't just about checking a single week's numbers - it's about spotting trends that show where your costs are heading. Tracking COGS as a percentage of sales is one of the easiest ways to do this. For most quick service restaurants, food costs often fall between 25% and 35% of sales, though this can vary by concept. If your percentage starts creeping up, it's a sign something needs attention.
Look for Red Flags -
1. Rising ingredient costs - If the price of a key item like chicken or cheese jumps, it can push your COGS up quickly.
2. Inconsistent portion sizes - Even small over-portioning adds up over hundreds of orders.
3. Increased waste - Spoiled or unused ingredients directly inflate your costs.
4. Seasonal spikes - Certain ingredients cost more during off-season months.
Compare and Drill Down
Break your COGS into categories - meat, produce, dairy, dry goods, beverages - and compare current costs to past weeks or months. This makes it easier to see which areas are causing the increase.
Act Quickly
The sooner you spot a problem, the easier it is to fix. That might mean adjusting your ordering, training staff on portion control, or promoting higher-margin menu items to offset costs.
When you make trend analysis part of your regular routine, you stop reacting to surprises and start making proactive changes that protect your profits.
Inventory Management and Waste Reduction Strategies
Good inventory management is one of the most effective ways to keep your COGS under control. Every ingredient you store is money sitting on your shelves, and if it goes unused or spoils, that money is gone. The goal is to keep the right amount of stock on hand - enough to meet demand, but not so much that waste becomes a problem.
Use the FIFO Method (First In, First Out)
Arrange your storage so that older stock is used before newer deliveries. This prevents ingredients from expiring at the back of the shelf. Clearly label items with delivery dates to make rotation easy for your team.
Track Inventory in Real Time
If possible, use an inventory management system that updates automatically when sales are made. This helps you spot when ingredients are running low or when certain items are moving slower than expected.
Standardize Portion Sizes
Inconsistent portions lead to hidden waste. Train staff to use measuring tools - like scoops, ladles, or portion scales - so every dish is made the same way. Even a small difference in serving size can add up to hundreds of dollars over time.
Identify and Reduce Waste Points
Keep an eye on common waste sources - over-prepping, incorrect orders, or spoilage due to poor storage. Track waste in a log so you can pinpoint repeat issues.
By combining strong inventory controls with waste reduction habits, you not only lower your COGS but also make your kitchen run more smoothly. Less waste means more profit, and that's a win every day.

Negotiating with Suppliers and Optimizing Purchasing
Once you understand your COGS and have accurate data on your ingredient costs, you can use that information to make smarter purchasing decisions. Supplier negotiation isn't just for large chains - every quick service restaurant can benefit from reviewing contracts, comparing prices, and finding ways to reduce costs without compromising quality.
1. Know Your Numbers
Before negotiating, make sure you have a clear picture of how much each ingredient costs and how much it contributes to your overall COGS. Suppliers respond better when you can demonstrate that you're aware of market prices and that you're making informed purchasing decisions.
2. Compare Multiple Suppliers
Don't rely on just one supplier for all your ingredients. Even a small difference in price per pound or per case can add up quickly across hundreds of orders. Comparing options regularly ensures you're getting competitive pricing.
3. Consider Volume and Frequency
Ordering in larger quantities can sometimes lower the unit cost, but it also increases the risk of waste if items aren't used quickly. Conversely, more frequent, smaller orders can reduce spoilage but may have higher per-unit costs. Use your COGS data to find the balance that fits your menu and sales volume.
4. Look for Flexibility in Terms
Negotiate delivery schedules, payment terms, or discounts for bundled orders. Flexibility can help you adjust to fluctuating sales or ingredient price swings without hurting your bottom line.
5. Monitor Regularly
Prices and availability change constantly. Make supplier review and renegotiation a regular part of your process to ensure you're always getting the best deal.
Using these strategies, you turn COGS analysis into actionable savings. By being proactive and data-driven, you can lower costs, reduce waste, and protect your profits without sacrificing quality or customer experience.
Using COGS Analysis for Menu Engineering
Your menu is more than a list of items - it's a powerful tool for controlling costs and maximizing profits. By using COGS analysis, you can understand which menu items are driving your expenses and which ones are contributing the most to your bottom line. This allows you to make smart decisions about pricing, portion sizes, and even which items to promote or adjust.
1. Identify High- and Low-Margin Items
Break down your menu and calculate the COGS for each item. Compare this to the selling price to determine the profit margin. Items with high costs relative to their price are low-margin and can hurt overall profitability if they sell in large volumes. Conversely, high-margin items provide more flexibility to cover other costs.
2. Adjust Pricing Strategically
Once you know the true cost of each menu item, you can price items to ensure they contribute fairly to profit. This doesn't always mean raising prices - sometimes it's about creating bundles, upsells, or promotions that increase average ticket value while keeping food costs manageable.
3. Standardize Portions
Portion size directly affects your COGS. Using standardized measurements for each ingredient ensures consistent quality and predictable costs. Even small adjustments, like reducing a sauce portion slightly, can add up to significant savings across hundreds of orders.
4. Promote High-Margin Items
Highlighting items that generate higher profits encourages customers to choose them, indirectly lowering your overall COGS percentage. Menu placement, visual cues, and staff recommendations can all play a role.
5. Monitor and Update Regularly
Ingredient prices fluctuate, and customer preferences change. Review your COGS and menu performance regularly to ensure your pricing, portions, and promotions remain effective.
By linking COGS analysis to menu decisions, you turn raw data into actionable strategies that improve profitability while keeping your offerings appealing and consistent.
Ongoing Monitoring and Profit Optimization
COGS analysis is not a one-time task - it's a continuous process that keeps your quick service restaurant profitable and efficient. Regular monitoring allows you to respond quickly to changes in ingredient prices, waste patterns, or sales trends, preventing small issues from turning into big losses.
1. Set Clear Targets
Establish target COGS percentages for your overall business and for individual menu items. For most QSRs, keeping food costs between 25% and 35% of sales is typical, but your targets should reflect your menu, pricing, and location. Clear targets give your team a benchmark to aim for.
2. Track COGS Consistently
Review your COGS weekly or monthly, depending on your sales volume. Compare current numbers to historical data to identify trends. Consistent tracking highlights areas where costs are creeping up, helping you make proactive adjustments.
3. Adjust Operations Based on Data
Use your findings to make informed decisions - whether it's adjusting portion sizes, reordering ingredients in different quantities, or revising menu pricing. These small operational tweaks can have a big impact on your profit margins.
4. Train Your Team
Staff play a crucial role in controlling costs. Train them on proper portioning, waste reduction, and accurate inventory handling. When your team understands how their actions affect COGS, they can contribute directly to profit optimization.
5. Review Regularly and Adapt
Ingredient prices fluctuate, customer preferences change, and sales patterns evolve. Schedule regular reviews of your COGS analysis and adjust your operations accordingly. The goal is to make data-driven decisions that maintain efficiency and protect profits.
Ongoing monitoring turns COGS analysis from a simple accounting exercise into a practical tool for managing your restaurant. By keeping a close eye on costs, making small but consistent improvements, and involving your team, you ensure that your restaurant stays profitable while serving quality food efficiently.
