Most restaurant owners think par levels are just fancy inventory numbers, but that's completely wrong. These standards actually control if you throw away €500 worth of vegetables or run a tight, profitable kitchen. Par levels tell you exactly how much of each ingredient to keep in stock and when to reorder.
What are par levels and why are they crucial?
Par levels are inventory standards per ingredient. They tell you:
- Minimum level: At this quantity you need to order
- Maximum level: You never need more than this
- Order frequency: How often you receive deliveries
Without par levels you're buying on gut feeling. That creates overordering, waste and cash flow problems. With solid par levels you avoid throwing away €500 worth of vegetables because you ordered way too much.
💡 Example:
Restaurant with 80 covers per day, 6 days per week:
- Salmon: consumption 3 kg per week
- Minimum level: 2 kg (for 5 days)
- Maximum level: 5 kg (never more than 10 days inventory)
- Order when: 2 kg or less
Result: Never more than €200 worth of salmon in the cooler
Calculate your weekly consumption per ingredient
The foundation of par levels is knowing exactly how much you use. For your top 20 ingredients, track:
- How many portions do you make per week of each dish?
- How many grams per portion do you use of this ingredient?
- Add up: total consumption per week
💡 Example calculation beef tenderloin:
- Steak: 25 portions per week × 220g = 5.5 kg
- Carpaccio: 15 portions per week × 80g = 1.2 kg
- Stew: 20 portions per week × 150g = 3.0 kg
Total beef per week: 9.7 kg
The 3-5-7 rule for par levels
A practical rule that works for most kitchens:
- Minimum level: 3 days consumption
- Order quantity: 5 days consumption
- Maximum level: 7 days consumption
For perishable products (fish, meat, fresh vegetables) you'll use shorter periods. For shelf-stable products (rice, pasta, canned goods) you can use longer periods.
⚠️ Note:
Always calculate with your busiest days, not your average. If you're 2× as busy on Saturday as on weekdays, calculate with that peak.
Adjust par levels per delivery schedule
Your par levels depend on how often your supplier delivers:
- Daily (fish, bread): Minimum 1 day, maximum 2 days
- 3× per week (fresh vegetables): Minimum 2 days, maximum 4 days
- 1× per week (meat): Minimum 3 days, maximum 10 days
- 1× per month (dry goods): Minimum 1 week, maximum 6 weeks
💡 Example meat (1× per week delivery):
Beef tenderloin consumption: 9.7 kg per week
- Minimum level: 4.2 kg (3 days × 1.4 kg/day)
- Order quantity: 10 kg (slightly more than weekly consumption)
- Maximum level: 14 kg (10 days inventory)
Order when inventory drops below 4.2 kg.
Factor in seasons and trends
Adjust your par levels for:
- Seasons: More soup in winter, more salad in summer
- Events: World Cup football, Valentine's Day, Mother's Day
- Holiday periods: Fewer guests during school holidays
- New dishes: Increase par level of new ingredients
Review your par levels every 3 months. Are they still realistic? Most kitchen managers discover too late that their spring par levels don't work for busy summer months, leading to constant stockouts or massive waste.
Digital tracking vs. Excel
Many kitchens track par levels in Excel or on paper. Problems:
- Forgotten updates after menu changes
- No link to actual inventory
- Difficult to share with team
An inventory app links your recipes to your ingredients. If you sell a dish more often, the recommended par level automatically increases. This keeps your standards current without manual updates.
⚠️ Note:
Par levels are guidelines, not absolute rules. If your supplier is a day late, or you have an unexpectedly busy evening, you need to be able to adjust.
Cost of incorrect par levels
Too high par levels cost you money in 3 ways:
- Waste: Products spoil before you use them
- Cash flow: Your money is tied up in inventory instead of in the bank
- Space: Full coolers mean less overview and control
💡 Cost savings example:
Restaurant reduces par levels by 20%:
- Inventory value drops from €8,000 to €6,400
- Waste drops from 12% to 8%
- On €200,000 annual revenue: €8,000 less waste
Total savings: €10,000+ per year
How do you set par levels? (step by step)
Measure your current consumption for 2 weeks
Note for your 20 most important ingredients how much you use each day. Add up what you use in total per week. This becomes your basis for the calculation.
Determine your delivery schedule per supplier
Write down how often each supplier delivers: daily, 2× per week, weekly. This determines how many days of inventory you need between deliveries.
Calculate minimum, order and maximum levels
Minimum = 3 days consumption, order quantity = 5 days consumption, maximum = 7 days consumption. Adjust for shelf life and delivery frequency.
Test and adjust for 1 month
Track whether your par levels are correct. Running into shortages? Increase the minimum. Throwing away a lot? Lower the maximum. Adjust until it works.
✨ Pro tip
Track your 6 highest-cost ingredients for 10 days straight before setting any par levels. You'll be shocked at how much your actual usage differs from what you thought you were using.

Frequently asked questions
What if my supplier is unreliable?
Increase your minimum level with 1-2 extra days of inventory as a buffer. Better to have slightly too much than to run out during service.
Do I need to set par levels for all ingredients?
Start with your 20 most expensive or most used ingredients. That gives you 80% of the results with 20% of the work.
How do I handle seasonal ingredients?
Create separate par levels for summer and winter menus. Asparagus has different par levels in May than in October.
