Food cost is the expense category in NZ hospitality where operators have the most direct control and the most consistent opportunity to improve margin. Unlike rent or labour, food cost responds directly to management attention. A venue that tracks it closely, reviews it weekly, and acts on the variances runs 3–5 percentage points better food cost than one that reviews it monthly and treats the number as a reporting exercise rather than a management tool.
What your food cost percentage should be
Food cost percentage — cost of goods sold as a percentage of food revenue — varies by category:
- Full-service restaurant kitchen: 28%–35% is the target range. Below 28% often means portion sizes or quality have been compromised. Above 35% means the pricing, purchasing, or waste position needs attention.
- Cafe kitchen: 28%–38% depending on the menu mix. Cabinet food tends to run higher cost percentage than cooked dishes; beverage cost is typically lower.
- Coffee: 12%–20% gross cost percentage. If your coffee cost is above 20%, your bean price, yield, or pricing structure needs review.
- Alcohol: 18%–28% for wine and spirits. Draft beer runs 22%–30% depending on your keg deal and portion management.
A mixed-service NZ venue — food, coffee, alcohol — should be targeting a blended food and beverage cost of 28%–33%. If you are running above 35% consistently, the causes are specific and addressable.
STAT: 3.2% · Average difference in food cost percentage between NZ venues that track daily and those that track monthly. Three percentage points on a $600,000 annual food revenue business is $19,200 in additional gross profit.
The tracking system that actually works
Accurate food cost tracking does not require specialist software. It requires consistent inputs.
Weekly food cost tracking:
- Opening stock value (counted at the start of the week)
- Plus all purchases received that week (invoice values, not payment dates)
- Minus closing stock value (counted at the end of the week)
- Divided by food revenue for the week
- The result is your actual weekly food cost percentage
This calculation takes 30 minutes per week if stock is organised and invoice records are current. It gives you a number that tells you whether your kitchen is running as expected or whether something needs attention.
The variances that matter:
- Actual cost more than 2 percentage points above target: investigate before it compounds
- Significant unexplained week-on-week movement: usually indicates a waste problem, a receiving problem, or a portioning issue
- Consistent seasonal movement: often reflects produce price changes and may require menu price adjustment
A food cost percentage that you look at monthly is a historical record. One you look at weekly is a management tool. The difference is whether you find out about problems before or after they have compounded.
The waste problem: the biggest driver of food cost variance in NZ hospo
Food waste is the largest controllable contributor to high food cost in most NZ restaurants and cafes. It takes three forms:
Prep waste: over-ordering, over-prepping, and trimming waste that exceeds recipe standards. A fish dish that yields 60% of the purchase weight is running at a different cost per portion than one calculated on 70% yield. The recipe costing and the actual kitchen practice need to be the same number.
Plate waste: portion sizes that diners cannot finish. If the garnish plate comes back half-eaten consistently, the portion is too large or the dish is not landing. Either reduce the portion and adjust the price, or fix the dish.
Spoilage: produce that goes off before it is used. This is almost always a purchasing discipline problem — ordering too much, not rotating stock, or not adjusting purchase quantities based on the actual cover count for the week ahead.
The intervention: a daily waste log, tracked by category, reveals which of these three sources is driving your variance. The kitchen hand noting “two portions of salmon trimmings, half-batch of soup stock” takes three minutes per day and produces a week’s worth of data that points directly at the problem.
NOTE: Before adjusting menu prices to address high food cost, spend one week tracking your kitchen waste in detail. In most cases, a 2–3 percentage point improvement is achievable through waste reduction alone without touching the pricing structure.
Supplier management as a food cost lever
The purchase price of your ingredients is a direct input to food cost. NZ venue operators who review their supplier arrangements quarterly, understand their actual usage volumes by ingredient, and negotiate based on commitment rather than one-off orders consistently run lower food cost than those who order from whoever is convenient.
Practical supplier management for NZ hospo:
- Know your top ten ingredients by spend and review the pricing on each quarterly
- Consolidate supplier count where quality allows — fewer suppliers means stronger individual relationships and better leverage
- Understand seasonal pricing patterns for produce and adjust menus to use what is at price, not what you have always served
- Ask for the trade price, not the listed price — most NZ food service suppliers have room in their pricing for consistent customers who ask directly

FACT: Zero commission on food revenue. $10/week after 20 bookings. 75% of no-show fees go to the venue.
Food cost control is a discipline, not a one-time exercise. The venues running the tightest food cost in NZ hospo are not working with better suppliers or smarter chefs than their competitors. They are tracking more carefully, reviewing more frequently, and acting on the variances before they compound. Three percentage points of improvement on a $500,000 food revenue business is $15,000 in annual gross profit. That number is worth the weekly 30-minute tracking exercise.
