Premium tonic can slash your cocktail profits by 6+ percentage points if you don't calculate properly. Most bar managers upgrade without knowing the real cost impact. Here's exactly how to calculate what that expensive tonic does to your bottom line.
Why a tonic upgrade can destroy your margin
Tonic might seem minor, but it represents 30-40% of your cocktail costs. A gin and tonic has just two main ingredients—every cost increase hits hard.
- Standard tonic: €0.35 per glass
- Premium tonic: €0.85 per glass
- Difference: €0.50 per cocktail
Serving 200 gin and tonics weekly? You're looking at €5,200 extra annually. Without raising prices, your profit disappears.
💡 Example: Gin and tonic upgrade
Standard gin and tonic (€9.50 excl. VAT):
- Gin (5cl): €1.20
- Standard tonic: €0.35
- Garnish: €0.15
Total: €1.70 → Pour cost: 17.9%
💡 Example: Premium upgrade
Premium gin and tonic (€9.50 excl. VAT):
- Gin (5cl): €1.20
- Premium tonic: €0.85
- Garnish: €0.15
Total: €2.20 → Pour cost: 23.2%
The formula for cocktail pour cost
Pour cost shows what percentage of your selling price goes to ingredients. It's your cocktail profitability metric.
Pour cost % = (Total ingredient costs / Selling price excl. VAT) × 100
Always calculate alcoholic beverages excluding 21% VAT. That €11.50 gin and tonic becomes €9.50 for calculations.
⚠️ Note:
Alcohol carries 21% VAT, not 9%. Calculate: €11.50 / 1.21 = €9.50 excl. VAT.
Calculate impact on annual basis
Small per-cocktail differences compound fast. After managing kitchen operations for nearly a decade, I've seen operators shocked by annual ingredient cost increases. Here's your calculation:
Annual impact = Difference per cocktail × Weekly volume × 52
💡 Example: Annual impact calculation
Premium tonic adds €0.50 per cocktail:
- 200 gin and tonics weekly
- 52 weeks annually
- €0.50 × 200 × 52 = €5,200 per year
Extra costs: €5,200 without price adjustment
When premium tonic pays for itself
Premium ingredients can boost profits if you raise prices and customers accept the increase.
- Increase price by €1.50 (€11.50 to €13.00)
- Extra revenue per cocktail: €1.24 excl. VAT
- Extra costs: €0.50
- Additional profit: €0.74 per cocktail
You'll earn €0.74 more per cocktail despite higher tonic costs. But only if customers accept the premium pricing.
Calculate different tonic options
Compare all options before deciding. Create a cost overview for each tonic tier.
💡 Example: Tonic comparison
At €9.50 selling price excl. VAT:
- Budget tonic (€0.25): Pour cost 16.8%
- Standard tonic (€0.35): Pour cost 17.9%
- Premium tonic (€0.85): Pour cost 23.2%
Gap between budget and premium: 6.4 percentage points
Tools to keep track of this
Manually calculating cocktail variations eats up time. Systems like KitchenNmbrs automatically show how ingredient changes affect pour costs.
Enter new tonic pricing and instantly see the impact across all cocktails. You can quickly determine which upgrades make financial sense.
How do you calculate the impact of more expensive tonic? (step by step)
Calculate current pour cost per cocktail
Add up all ingredient costs (gin, tonic, garnish). Divide by selling price excl. 21% VAT and multiply by 100 for percentage.
Calculate new pour cost with premium tonic
Replace the tonic price with the more expensive variant. Recalculate the total ingredient costs and new pour cost percentage.
Calculate impact on annual basis
Multiply the cost difference per cocktail by the number of cocktails sold per week and 52 weeks. This gives you the total annual impact.
✨ Pro tip
Track your top 3 gin-based cocktails for 2 weeks before switching tonics. If those maintain healthy 20% pour costs with premium tonic at current prices, you've got room to upgrade without repricing.

Frequently asked questions
Should I calculate 9% or 21% VAT for cocktails?
Alcoholic beverages always carry 21% VAT. So a €11.50 gin and tonic equals €9.50 excl. VAT for calculations. Non-alcoholic cocktails use 9% VAT.
What's a healthy pour cost for cocktails?
Target 18-25% pour cost for cocktails. Simple drinks like gin and tonic can run lower, while complex multi-ingredient cocktails may push higher.
How often should I adjust cocktail prices?
Review ingredient prices quarterly minimum. Spirit and premium mixer costs can spike without warning, silently eroding your margins.
Can I pass premium tonic costs to customers without losing them?
Depends on your positioning and clientele. Test with a limited cocktail selection first and monitor customer response before rolling out broadly.
Should garnish be included in cost calculations?
Absolutely include garnish costs. That lime wheel or olive seems negligible, but high-volume operations see significant impact over time.
What if my pour cost exceeds 25% after the tonic upgrade?
Either raise your selling price or reconsider the upgrade. Pour costs above 25% typically signal pricing problems that need immediate attention.
How do I calculate the break-even price increase for premium tonic?
Add the tonic cost difference to your target profit margin, then multiply by 1.21 for VAT. This gives you the minimum menu price increase needed.
