Most bar owners think homemade syrup costs just the price of sugar - and wonder why their margins keep shrinking. You're paying for water, gas, labor, spoilage, and time, but only tracking the €1.20 worth of sugar. Here's how to calculate the real cost of every homemade cocktail ingredient.
Why calculate homemade ingredients differently?
A bottle of vodka has a fixed cost per pour. Homemade sugar syrup? That's where things get messy. You've got raw materials, energy costs, labor time, and spoilage eating into your margins.
⚠️ Watch out:
Most bars count only the sugar (€1.20/kg) and think syrup costs €0.60 per liter. But you're also paying for water, gas, time, and dealing with spoilage losses.
The real cost of homemade syrup
For accurate pricing, track these components:
- Raw materials: sugar, water, flavorings
- Energy: gas or electricity for cooking
- Labor: prep and bottling time
- Packaging: bottles, labels
- Loss: spoilage before use
💡 Example: Simple sugar syrup (1 liter)
For 1 liter sugar syrup (1:1 ratio):
- 500g sugar: €0.60
- 500ml water: €0.01
- Gas 15 minutes cooking: €0.25
- Labor 20 minutes at €15/hour: €5.00
- Bottle + label: €0.30
Total: €6.16 per liter = €0.62 per 10cl
Should you include labor costs?
Depends on timing. If your bartender's making syrup during slow periods, factor in labor. Making it at home on your own time? You might skip labor costs.
But here's what we recommend: always include a standard €15/hour labor rate. This gives you honest comparisons with store-bought alternatives and prevents you from fooling yourself about true costs.
Spoilage rates and shelf life
Homemade syrups don't last like commercial ones. Factor in these loss percentages - it's a pattern we see repeatedly in restaurant financials where bars underestimate spoilage:
- Sugar syrup: 4 weeks shelf life, 10% loss
- Fruit syrup: 2 weeks shelf life, 15% loss
- Herbal infusions: 6 weeks shelf life, 5% loss
💡 Example: Calculating loss percentage
You make strawberry syrup for €8.00 per liter, but 15% spoils:
Actual cost price: €8.00 / 0.85 = €9.41 per liter
Per 2cl (standard portion): €0.19 instead of €0.16
Compare with store-bought options
Don't assume homemade's always cheaper. Monin sugar syrup runs €6.50 per liter with zero labor costs or spoilage risk.
Homemade makes financial sense for:
- Unique flavors unavailable commercially
- High-volume usage (5+ liters weekly)
- Seasonal specialties (fresh strawberry syrup in summer)
Track it in your cost system
Treat homemade ingredients like any other purchase in your costing software. Build a "recipe" for each syrup including all cost components, then use that recipe as an ingredient in cocktail calculations.
💡 Example: Mojito with homemade mint syrup
Cocktail breakdown:
- 6cl white rum: €1.80
- 2cl mint syrup (homemade): €0.24
- 3cl lime juice: €0.45
- Fresh mint: €0.30
- Soda water: €0.15
Total ingredient costs: €2.94
At €12.00 selling price (excl. 21% VAT = €9.92): Pour cost 29.6%
How do you calculate the cost price of homemade syrup?
Gather all raw materials and costs
Note exactly what you need: sugar, water, any fruits or herbs. Also include energy (gas/electricity), packaging (bottles), and your time at €15 per hour.
Add up all costs per batch
For example, make 1 liter and add up all costs. Divide by the number of liters you get for the cost price per liter.
Include loss percentage due to spoilage
Divide your cost price by the yield (100% minus loss percentage). At 10% loss: divide by 0.90. This gives you the actual cost price per liter.
✨ Pro tip
Make 2-liter batches every 10 days to optimize labor costs per liter - any larger and spoilage costs exceed your labor savings.

Frequently asked questions
Should I always include labor time in homemade syrups?
For honest comparison with store-bought alternatives, absolutely. Calculate €15 per hour, even during slow periods. Otherwise homemade always looks cheaper than reality.
How long do homemade syrups actually keep?
Simple sugar syrup lasts 4 weeks, fruit syrups just 2 weeks, alcohol-based infusions up to 6 weeks. Refrigerate everything and factor 5-15% spoilage loss into your cost calculations.
How do I register homemade ingredients in my costing system?
Create a "recipe" for your syrup including all costs - raw materials, energy, labor, spoilage losses. Use this recipe as an ingredient in cocktail calculations, same as bottled spirits.
Should I include VAT on homemade ingredient costs?
No, calculate VAT only on your final cocktail selling price (21% on alcohol). Homemade ingredient costs are internal cost prices without VAT included.
