Restaurant Food Cost Percentage (How to Get Yours Under 30%)
If you’ve ever looked at your food cost percentage and thought, “that can’t be right,” you’re probably not wrong.
Food cost is the number that sneaks up on restaurant owners the most, and it’s the one that quietly eats your margin while you’re busy running a full dining room.
Getting food cost under control doesn’t require a total menu overhaul or firing your kitchen staff.
It requires knowing the number, understanding what’s driving it, and making a few targeted changes that actually stick.
We work with restaurant owners across the country on exactly this, and we see the same culprits come up over and over.
Food Cost Percentage is The One Number That Can Make or Break Your Restaurant
Food cost percentage tells you what fraction of every dollar in food sales goes directly to buying the food you sold. If your food sales for the week are $20,000 and you spent $6,500 on food, your food cost percentage is 32.5%. That number is either your friend or your enemy, depending on where it lands.
Food cost also doesn’t live in a vacuum. It’s one half of prime cost, which is food cost plus labor cost combined. Our prime cost breakdown puts the target at 55-60% for full-service restaurants and 60-65% for quick-service, and once you drift above 65%, you’re working for your suppliers and staff, not for yourself. When food cost creeps up, prime cost follows, and margin compresses fast.
We walk through how the two numbers work together in prime cost vs food cost for restaurants.
Once you know what the number means, the next question is always: what should mine actually be?
What is a Good Food Cost Percentage for a Restaurant?
Most restaurants aim to keep food and beverage costs between 28% and 32% of food and beverage revenue, and that’s the range we point owners to. The best operators get below it, but only with tight portion control, smart ordering, and real-time tracking. Fine dining often runs a little lower because their labor % mix is much higher compared to quick-service concepts that can run higher on food too because portion sizes are non-negotiable, which they balance with leaner labor.
Where you land within that range matters less than whether your number is consistent and trending in the right direction. A restaurant running 31% every week and improving is in far better shape than one that was at 28% last month and has no idea it’s at 36% this month.
The math matters more than the percentage alone, too. A higher-ticket concept can run a food cost in the low 30s and still generate strong gross margin dollars per cover. That’s why we always look at food cost alongside actual margin dollars, not the percentage in isolation.
To use a benchmark, though, you have to know how to calculate the number correctly. That’s where a lot of restaurants slip up.
How Do You Calculate Food Cost Percentage?
Food cost percentage equals Food Costs divided by Food Revenue, multiplied by 100. Simple enough on paper, but getting an accurate COGS number is where most restaurants go wrong.
Accurate COGS requires tracking your beginning inventory, adding your purchases for the period, and subtracting your ending inventory. The formula: (Beginning Inventory + Purchases) – Ending Inventory = COGS. Divide that by food revenue for the period and multiply by 100.
The place most restaurant owners flinch is the inventory count. Counting inventory at least bi-weekly is the only way to get a real-time picture of what’s happening in your kitchen, especially for operations that have different seasonalities. Monthly counts leave too much time between data points. By the time you see a problem in a monthly P&L, it’s been going on for four weeks. We set all our restaurant clients up on Xero for accounting, which syncs with your POS and makes the COGS math a lot cleaner when your inventory adjustments feed in properly.
Once you’re calculating the number accurately, the next step is hunting down what’s inflating it. Portioning is usually the first place to look.
Portion Control is the Fastest Lever Most Restaurants Ignore
Inconsistent portioning is one of the leading causes of food cost creep, and it’s almost always invisible to ownership until someone runs a plate audit. When your line cook plates 6 oz of protein on a dish priced for 5 oz, you just added 20% to the cost of that item without changing a single thing on your menu or vendor invoice.
Run the math on a burger. It’s priced based on a 6 oz patty, but nobody’s weighed a patty since training month, and the line is actually plating 7.5 oz. That’s 25% more beef on every plate than you priced for, and since the patty is most of the plate cost, a burger you costed under 30% quietly lands in the mid-30s. If burgers are a big part of your sales mix, that one drift shows up in your overall food cost, even though your menu costing spreadsheet still looks clean.
The fix is portion specs, scales on the line, and a manager who’s actually checking. The solution isn’t complicated. The discipline to maintain it is the hard part, and addressing it naturally leads you to look at the next driver: what you’re paying for your products in the first place.
Purchasing and Vendor Relationships Drive Food Cost More Than Most Owners Realize
Your food cost starts before anything hits the kitchen. What you pay for product, how often you’re getting deliveries, and whether you’re actually comparing prices across vendors all show up in your cost percentage before the food ever touches a cutting board.
A few things we see consistently: restaurants that order too frequently in small quantities pay more per unit. Restaurants that never push back on vendor price increases absorb every market spike without a fight. And restaurants that don’t track what they’re actually receiving versus what was invoiced leave money on the table through short deliveries and substitutions they paid full price for.
A useful practice is to review your top 10 highest-cost ingredients quarterly and get competing quotes. You don’t have to switch vendors, but knowing the market price keeps your primary vendor honest. Using Syft Analytics on top of your accounting data turns the bills and totals in Xero into trend lines, so you can see where vendor cost increases are hitting your COGS instead of discovering it a month later on your P&L.
Getting purchasing under control brings your input costs down. But if your pricing and menu mix aren’t set up well, you can still leave margin on the table even with good vendor relationships.
Menu Engineering Turns Your Best Sellers into Your Most Profitable Items
Menu engineering is the process of categorizing every item by popularity and profitability, then using that information to adjust pricing, placement, and portion strategy. The core of it is a simple grid: high-margin/high-popularity items are your stars, low-margin/high-popularity items (plowhorses) need repricing or recipe rework, and low-margin/low-popularity items (dogs) get cut.
A menu engineering pass every six months is a realistic cadence for most independent restaurants. If you haven’t looked at your menu this way since you opened, there’s almost certainly margin sitting on the table. Our restaurant accounting clients often find that two or three recipe tweaks or price adjustments on top-selling items can close a meaningful gap in food cost without a single customer noticing.
Better menu mix helps your food cost percentage even when your purchasing costs stay flat. The other side of that coin is how often you’re actually looking at the number, which brings us to tracking cadence.
Tracking Food Cost Weekly Keeps You Ahead of the Problem
Monthly P&L reviews are better than nothing, but by the time you see a food cost spike in a monthly report, you’ve already lost four weeks of margin. Weekly food cost tracking is what separates restaurants that catch problems early from those that find out during a bad quarter.
The weekly rhythm doesn’t have to be complicated. Count your high-velocity items (proteins, cheese, bread), log your purchases for the week, and calculate a flash food cost. It won’t be as precise as a full inventory count, but it’ll tell you quickly whether you’re tracking above or below target and give you a week to investigate before the problem compounds.
The flash count lives with you and your kitchen manager, and your POS holds the item-level detail. On our side, Xero pulls in your daily sales totals and vendor bills, and Syft turns them into a trend you can check against your flash number. When something moves, you can trace it: did a vendor price jump? Did a line cook switch? Did a new menu item underperform on cost? Weekly data makes that conversation possible.

We’ll figure out where the leaks are.
Until next time!
