Calculating accurate soft serve margins means tracking every cost beyond just the ice cream mix. Most shops overlook energy, water, and packaging expenses that quietly eat into profits. Here's exactly how to calculate your real margin per portion.
What does a portion of soft serve ice cream really cost?
Soft serve ice cream involves more than just the mix. There are hidden costs that add up:
- Ice cream mix: The base of your ice cream
- Energy: The machine runs continuously
- Water: For cleaning and cooling
- Packaging: Cone, cup or container
- Toppings: Chocolate sauce, nuts, sprinkles
💡 Example:
Portion of soft serve ice cream (150ml) with cone:
- Ice cream mix: €0.45
- Cone: €0.12
- Energy (per portion): €0.08
- Water and cleaning: €0.03
Total cost price: €0.68
Calculating the ice cream mix
Ice cream mix gets sold per liter or per kilo of powder. You'll get about 6-8 portions of 150ml from one liter, but this depends on overrun (how much air gets whipped in).
⚠️ Note:
Calculate with your actual portion size. A 'small' portion can easily become 180ml if your staff scoops generously.
Energy costs per portion
Soft serve machines consume 2-4 kW per hour on average. Say you serve 100 portions daily and run the machine 8 hours - you can break down energy costs per portion like this:
💡 Example energy costs:
Machine: 3 kW, runs 8 hours per day
- Consumption per day: 3 × 8 = 24 kWh
- Cost per day: 24 × €0.30 = €7.20
- At 100 portions: €7.20 ÷ 100 = €0.07 per portion
Packaging and toppings
Packaging costs add up fast. Waffle cones run €0.08 to €0.15 each. Plastic cups cost less, but you'll need wooden spoons. From years of working in professional kitchens, I've seen how toppings can make or destroy your margins:
- Chocolate sauce: €0.05-0.10 per portion
- Nuts: €0.15-0.25 per portion
- Sprinkles: €0.03-0.06 per portion
From cost price to selling price
Once you've got your total cost price, you can figure out your margin. For soft serve, aim for 25-35% food cost. Higher percentages mean you're not earning enough to cover other expenses.
💡 Example margin calculation:
Cost price: €0.68, Selling price: €2.50 (incl. 9% VAT)
- Selling price excl. VAT: €2.50 ÷ 1.09 = €2.29
- Food cost: (€0.68 ÷ €2.29) × 100 = 29.7%
- Margin per portion: €2.29 - €0.68 = €1.61
Accounting for seasonal fluctuations
Summer might bring 200 portions daily, winter just 20. Your energy costs per portion will spike because the machine still needs to run. So calculate using yearly averages. A food cost calculator (like KitchenNmbrs) can help track these seasonal variations automatically.
How do you calculate the margin on soft serve ice cream?
Calculate the cost price of the ice cream mix
Divide the price of a liter of mix by the number of portions you get from it. Calculate with 6-7 portions of 150ml per liter of mix, depending on your machine.
Add up all extra costs
Add: packaging (cone/cup), energy costs per portion, water for cleaning, and any toppings. These costs are often forgotten but add up.
Calculate your margin
Subtract the total cost price from your selling price (excl. VAT). For soft serve ice cream, a food cost of 25-35% is normal. Above 35% you're not earning enough.
✨ Pro tip
Weigh every 15th portion during your busiest 3-hour period for two weeks straight. Most shops serve 25-40% larger portions than calculated, which destroys margin projections.

Frequently asked questions
How many portions do I get from a liter of ice cream mix?
You'll get 6-7 portions of 150ml on average, depending on your machine's overrun. Modern machines typically achieve 40-60% overrun, which affects your yield calculations.
Should I include VAT in my margin calculation?
No, always work with selling prices excluding VAT. Soft serve falls under 9% VAT, so divide your menu price by 1.09 to get the pre-tax amount.
What are realistic energy costs per portion?
Expect €0.05 to €0.12 per portion, depending on your machine and daily volume. Lower sales mean higher per-portion costs since fixed energy expenses get spread across fewer servings.
How do I handle seasonal sales fluctuations in my calculations?
Create yearly averages for your sales volume. Summer sales help offset winter's higher per-portion fixed costs like energy and equipment depreciation.
What food cost percentage should I target for soft serve?
Aim for 25-35% of your selling price excluding VAT. Higher percentages leave too little margin to cover labor, rent, and other operational expenses.
How do I calculate overrun impact on my costs?
Measure your actual output versus mix input over a full day. If 1 liter of mix produces 1.5 liters of finished product, you have 50% overrun, which reduces your per-portion mix cost.
Should I factor in machine depreciation costs?
Yes, especially for expensive commercial machines. Divide your machine cost by expected lifespan (usually 5-7 years) and daily portions to get depreciation per serving.
