Think of your ingredient purchases like a wardrobe – 20% of your clothes get worn 80% of the time. ABC analysis works the same way, helping you identify which ingredients consume most of your budget. You'll discover where your money actually goes and where smart negotiations create the biggest savings.
What is an ABC analysis?
An ABC analysis divides your ingredients into three groups based on their financial impact:
- A-category: 20% of your ingredients that represent 80% of your purchasing value
- B-category: 30% of your ingredients that represent 15% of your purchasing value
- C-category: 50% of your ingredients that represent only 5% of your purchasing value
This principle follows the 80/20 rule, also called the Pareto principle.
💡 Example ABC distribution:
Restaurant with €15,000 monthly purchases:
- A-category: Beef, fresh fish, truffles (€12,000)
- B-category: Vegetables, dairy, spices (€2,250)
- C-category: Salt, pepper, toothpicks (€750)
Why an ABC analysis matters
Categorizing ingredients lets you focus energy where it creates real impact. A-ingredients need intensive control and sharp negotiation, while C-ingredients can be stocked with minimal oversight.
- Save time by focusing on the most critical 20% of your ingredients
- Negotiate better prices for A-category items
- Prevent overstocking of expensive ingredients
- Optimize your cashflow
Gathering data for your analysis
You need at least 3 months of purchasing data for reliable results. Collect this information per ingredient:
- Total purchasing value over the period
- Number of times ordered
- Average order quantity
- Price per unit
⚠️ Note:
Use purchasing value, not sales value. You're tracking what you spend on purchases, not what you earn from them.
Calculation and categorization
After gathering your data, sort all ingredients by purchasing value from high to low. Then calculate the cumulative percentage:
Cumulative percentage = (Running total / Total purchasing value) × 100
💡 Example calculation:
Top 5 ingredients of a restaurant with €10,000 total purchases:
- Beef: €3,000 (30% cumulative)
- Fresh fish: €2,500 (55% cumulative)
- Veal: €1,500 (70% cumulative)
- Lobster: €1,000 (80% cumulative) ← A-boundary
- Vegetables: €800 (88% cumulative)
The first 4 ingredients form the A-category (80% of value).
Practical application per category
A-category management:
- Daily inventory control
- Negotiate annual contracts with fixed prices
- Research alternative suppliers
- Keep minimal stock to optimize cashflow
B-category management:
- Weekly inventory control
- Periodic price comparisons
- Maintain average inventory levels
C-category management:
- Monthly control
- Bulk purchasing for economies of scale
- Higher inventory levels allowed
💡 Real restaurant P&L data:
Based on actual bistro data, ABC analysis revealed:
- 5 ingredients represented 75% of their purchases
- Negotiating better on these 5 items saved €400/month
- This generated €4,800 extra profit per year
Digital tools for ABC analysis
Manual ABC analysis in Excel consumes hours and invites errors. Modern systems automate this process by analyzing your purchasing data and automatically categorizing ingredients.
Systems can keep your purchasing data centralized and automatically reveal which ingredients consume most of your budget. This saves you hours of work monthly.
How do you perform an ABC analysis? (step by step)
Gather 3 months of purchasing data
Make a list of all ingredients with their total purchasing value over the past 3 months. Only include actual purchasing costs, no VAT or other surcharges.
Sort by purchasing value
Rank all ingredients from high to low based on their total purchasing value. The most expensive ingredients appear at the top of your list.
Calculate cumulative percentages
Calculate the cumulative percentage of your total purchases for each ingredient. Ingredients that together represent 80% form your A-category.
Divide into A, B and C categories
A-category: 0-80% of value, B-category: 80-95% of value, C-category: 95-100% of value. Adjust your purchasing strategy per category.
✨ Pro tip
Start with your top 8 A-category ingredients over the next 30 days. Negotiating just 7% better pricing on these items typically delivers more profit impact than optimizing your entire C-category.

Frequently asked questions
How often should I update my ABC analysis?
Update your ABC analysis every 3-6 months. Seasons, menu changes, and price fluctuations can shift the proportions significantly.
What if an ingredient suddenly jumps from C to A category?
This happens with seasonal products or new popular dishes. Adjust your purchasing strategy immediately and start monitoring and negotiating more intensively.
Should I include beverages in my ABC analysis?
Yes, but create a separate analysis for beverages. The proportions differ and your purchasing strategy for alcohol varies from food items.
Can I adjust the ABC boundaries for my restaurant type?
Absolutely – the 80/15/5 distribution serves as a guideline. Some restaurants use 70/20/10 or other proportions that better match their concept and volume.
How do I handle rarely-ordered but expensive specialty ingredients?
These often fall into A-category due to their high value. Order them only for confirmed guest requests or find cheaper alternatives for your standard menu offerings.
What's the minimum purchase volume needed for meaningful ABC analysis?
You need at least €5,000 monthly purchases across 50+ different ingredients. Smaller operations might not see clear category distinctions and should focus on their top 10 most expensive items instead.
