While most bar managers obsess over premium gin costs, they often ignore the mixer sitting right next to it. That €0.60 worth of tonic water actually represents 30-40% of your total drink cost. A 15% tonic price bump can quietly destroy your margins faster than you'd think.
Why tonic prices hit your margins hard
Here's what catches most bartenders off guard: a gin-tonic isn't just gin with a splash of mixer. The tonic, lime, and ice typically account for 35-40% of your ingredient costs. And when that tonic price jumps? Your cost per drink shoots up instantly.
💡 Example current situation:
Gin-tonic at €9.50 (incl. 21% VAT) with these costs:
- Gin (5cl): €1.20
- Tonic (20cl): €0.60
- Lime + ice: €0.15
Total costs: €1.95 | Pour cost: 25%
Crunch the numbers on that price hike
Let's say your supplier hits you with a 15% increase. Your tonic jumps from €3.00 per liter to €3.45. For each gin-tonic, you're using 20cl of that pricier tonic.
💡 Calculation of new costs:
- Old tonic: €3.00/liter = €0.60 per 20cl
- New tonic: €3.45/liter = €0.69 per 20cl
- Difference: €0.09 per gin-tonic
New total costs: €1.95 + €0.09 = €2.04
Your new pour cost reality
Stick with that €9.50 selling price, and watch your pour cost climb. But remember—always work with pre-VAT numbers for accurate margin calculations.
- Selling price excl. 21% VAT: €9.50 / 1.21 = €7.85
- New pour cost: (€2.04 / €7.85) × 100 = 26.0%
- Was: 24.8% → Now: 26.0% = 1.2 percentage point increase
⚠️ Note:
Always calculate pour cost with the price excluding VAT. Alcoholic beverages carry 21% VAT, not the 9% you see on food.
The yearly damage adds up fast
That measly €0.09 per drink? It's sneakier than you think. From years of working in professional kitchens, I've seen how these small increases compound. If you're moving 50 gin-tonics weekly:
- Per week: 50 × €0.09 = €4.50
- Per year: €4.50 × 52 = €234
Got a popular cocktail program pushing 150 gin-tonics weekly? You're looking at €702 in annual cost creep.
Fix your selling price
Want to maintain that original 25% pour cost? Time to bump your price. Here's your new minimum:
💡 New price calculation:
- Desired pour cost: 25%
- New costs: €2.04
- Minimum price excl. VAT: €2.04 / 0.25 = €8.16
- Price incl. 21% VAT: €8.16 × 1.21 = €9.87
Round to: €9.90 or €10.00
Smart alternatives to price hikes
Price increases aren't always possible. Here are your other moves:
- Switch tonic brands: Hunt down a supplier with better price-to-quality ratio
- Volume purchasing: Negotiate discounts on larger orders
- Portion adjustment: Drop to 18cl tonic instead of 20cl (saves €0.035 per cocktail)
- Dynamic pricing: Keep old prices during slow periods, implement new prices at peak times
Tools like a food cost calculator help you spot these margin impacts across your entire cocktail menu instantly.
How do you calculate the impact of a tonic price increase? (step by step)
Calculate current costs per cocktail
Add up all ingredient costs: gin, tonic, garnish and ice. Note the current tonic price per liter and calculate what 20cl (or your standard portion) costs.
Calculate new tonic costs
Multiply the old tonic price by the percentage increase. Calculate what your new tonic portion costs and add this to the other ingredients.
Calculate new pour cost percentage
Divide the new total costs by your selling price excluding 21% VAT and multiply by 100. Compare this with your desired pour cost of 18-25%.
✨ Pro tip
Track your tonic usage over the next 30 days—if you're moving more than 200 cocktails weekly with tonic, even a €0.05 cost increase per drink hits you for €520 annually.

Frequently asked questions
What's an acceptable pour cost range for gin-tonics?
Most profitable bars target 18-25% pour cost for cocktails. Gin-tonics typically land around 22-25% since quality tonic water costs more per serving than basic mixers.
Should I immediately raise prices when ingredient costs jump?
Not necessarily. First explore switching tonic brands, negotiating volume discounts, or slightly reducing portions. Sometimes absorbing a 1-2 percentage point pour cost increase makes more sense than risking customer pushback.
How do I factor VAT into pour cost calculations correctly?
Always calculate pour cost using pre-VAT prices. A €10.00 gin-tonic becomes €8.26 excluding the 21% VAT on alcoholic beverages. This gives you accurate margin data for decision-making.
