Nearly 40% of care catering contracts fail within their first year due to calculation errors that could've been prevented. Suppliers repeatedly forget hidden costs, miscalculate portion sizes, or estimate occupancy rates far too optimistically. Here are the 7 most common mistakes and how to avoid them.
The 7 biggest calculation errors in care catering
⚠️ Heads up:
One calculation error can ruin your entire quote. In care catering, margins are often tight, so every euro counts.
1. Incorrect VAT calculation for care catering
Most care caterers forget that care catering has 0% VAT if it's medically necessary. But not all care catering falls under this category.
💡 Example VAT difference:
Meal at €8.00 per person:
- Hospital (medical): €8.00 (0% VAT)
- Care home (comfort): €8.72 incl. 9% VAT
- Actual price excl. VAT: €8.00
Difference in cost price: €0.72 per meal
2. Too optimistic occupancy rate
Many caterers calculate with 95% occupancy, but reality's often lower. Residents get sick, visit family, or end up in the hospital - it's the kind of thing you only learn after closing your first month at a loss.
💡 Example occupancy rate:
Care home with 100 residents:
- Calculated: 95 meals per day
- Actual: 87 meals per day
- Difference: 8 meals × €8 = €64/day
Annual loss: €23,360
3. Forgetting special diet costs
Care catering involves many special diets: diabetes, heart disease, swallowing disorders. These cost 20-40% more than standard meals.
- Diabetes diet: +25% costs (sugar-free products)
- Heart-friendly: +30% costs (less salt, better oils)
- Finely chopped: +40% costs (extra preparation time)
4. Underestimating food waste
Food waste runs higher in care catering than restaurants. Residents eat less, have varying appetites, or receive unexpected visitors.
💡 Example food waste:
Daily production 100 meals at €5 ingredient costs:
- Restaurant waste: 8% = €40
- Care catering waste: 15% = €75
- Extra loss per day: €35
Annual extra loss: €12,775
5. Incorrect calculation of labor costs
Care catering requires more staff per meal. You'll need to portion, distribute across departments, and often serve individually.
⚠️ Heads up:
Calculate with 1.5-2x more staff time than regular catering. Don't forget to include breaks and sick leave.
6. Incorrect calculation of transport costs
Transport in care catering costs more because you often deliver multiple times per day and need special insulated containers.
- Fuel: Multiple trips per day
- Insulated equipment: Rental €50-100/month per container
- Extra time: Unloading and distributing across departments
7. Not accounting for seasonal variations
Residents eat more in winter, less in summer. Many caterers calculate with an average, but reality fluctuates significantly.
💡 Example seasonal variation:
Care home 100 residents:
- Winter: 92 meals/day
- Summer: 78 meals/day
- Difference: 14 meals × €8 = €112/day
3 summer months: €10,080 less revenue
How do you prevent these errors?
The solution is working systematically with realistic figures. Use historical data from comparable locations and always calculate with a safety margin.
- VAT: Check per location whether 0% or 9% applies
- Occupancy: Calculate with 85-90% instead of 95%
- Special diets: Count 30% of residents as having a special diet
- Waste: Calculate with 12-15% instead of 8%
- Staff: Plan 1.8x more time than regular catering
Systems like KitchenNmbrs let you record these variables per location and automatically calculate them into your cost price.
How do you calculate care catering cost price correctly?
Determine your actual occupancy rate
Take historical data from 6 months and calculate the average number of meals delivered per day. Don't calculate with the maximum number of residents, but with actual consumption.
Calculate ingredient costs including special diets
Add up all ingredient costs and add 25-30% for special diets. Also include 12-15% food waste instead of the usual 8% in regular catering.
Calculate labor and transport costs realistically
Plan 1.8x more staff time than normal catering and include all transport costs including insulated equipment. Divide this by your actual number of meals per day.
✨ Pro tip
Track actual vs. projected costs for your first 30 days on any new contract. Document the variance in occupancy rates, waste percentages, and special diet requests to refine future quotes.
