How to Calculate Beverage Pour Cost from a Bottle or Keg
Calculate beverage cost per pour from container volume, measured loss, allocation model, mixer cost, and selling price.
A bottle or keg can produce a fractional number of pours, and the treatment of the remainder changes the cost assigned to each pour. The beverage pour calculator makes that choice explicit: continuous allocation keeps the remaining liquid in usable stock, while whole-pour allocation assigns the full container price across complete pours. This guide follows the whole-pour case through measured loss, mixer cost, and pour-cost percentage, then compares it with continuous allocation so the result is not misread.
How to cost a pour on the declared allocation model
- Use one matching volume unit. Enter container volume and pour volume in the same unit, such as milliliters or US fluid ounces. The calculator carries the label but performs no automatic conversion.
- Enter measured loss only once. Use a loss percentage only for a separately measured loss before portioning. If the container volume is already usable volume, leave loss blank; do not subtract the same loss twice.
- Choose continuous or whole-pour allocation. Continuous allocation divides the container price across the usable volume and the pour size. Whole-pour allocation divides the full container price by the number of complete pours and absorbs the remainder into those pours.
- Add mixer ingredients per pour. Enter already-costed mixer ingredients for one pour when applicable. Packaging, fees, and general operating costs are outside this calculator.
- Compare cost with the same selling price. Use T49 with the selected pour cost and the price charged for that same pour. A different glass size or price needs a separate calculation.
From container volume to pour-cost percentage
- Record Container and pour
Price, full volume, and one pour in matching units.
- Adjust Measured loss
Usable volume = container volume × (1 − loss fraction).
- Allocate Continuous or whole-pour
Choose whether the remainder stays in stock or is absorbed by complete pours.
- Compare Pour cost and ratio
Add mixer cost, then divide by the matching selling price.
Choose the allocation model before reading the cost
The same container can produce different per-pour results under the two declared remainder policies. The difference is a cost-allocation choice, not an automatic unit conversion.
| Model | Beverage-cost equation | Remainder treatment | Best use |
|---|---|---|---|
| Continuous | Container price × pour volume ÷ usable volume | Remaining liquid stays in usable stock | Costing liquid consumption while retaining stock value. |
| Whole-pour | Container price ÷ floor(usable volume ÷ pour volume) | Remainder is absorbed once into complete pours | Costing a service run where only complete pours are assigned. |
| Mixer addition | Selected beverage cost + mixer cost per pour | Mixer is already valued for one pour | Keep packaging and fees outside this input. |
| Pour-cost percentage | Pour cost ÷ selling price × 100 | Uses the selected pour cost | Price must match the same beverage pour. |
Measure the volume basis before dividing
Use the container volume and pour volume in the same dimension and unit. A 750 mL bottle with a 40 mL pour can be calculated directly; a fluid-ounce pour requires a container volume expressed in fluid ounces or a verified conversion before using the form. The calculator does not infer density or convert units.
Worked example: 750 mL bottle, 40 mL pour
A 750 mL bottle costs $24.00. The measured pour is 40 mL, measured loss is 10%, mixer ingredients cost $0.20 per pour, and the chosen model is whole-pour allocation. The beverage sells for $8.00 per pour.
Inputs
- Container price
- $24.00
- Container volume
- 750 mL
- Pour volume
- 40 mL
- Measured loss
- 10 %
- Mixer cost
- $0.20 per pour
- Selling price
- $8.00 per pour
- Usable volume = 750 mL × (1 − 0.10) = 675 mL.
- Theoretical pour equivalents = 675 ÷ 40 = 16.875; complete pours = floor(16.875) = 16, with a 35 mL remainder.
- Whole-pour beverage cost = $24.00 ÷ 16 = $1.50; total pour cost = $1.50 + $0.20 mixer = $1.70.
- Pour-cost percentage = $1.70 ÷ $8.00 × 100 = 21.25%, displayed as 21.3%.
- Usable volume: 750 mL × 0.90 = 675 mL
- Complete pours: floor(675 ÷ 40) = 16 pours
- Remainder: 675 − (16 × 40) = 35 mL
- Percentage: $1.70 ÷ $8.00 × 100 = 21.25% → 21.3%
Result: $1.70 / pour with 21.3% pour cost
Keep usable volume, theoretical pours, and the remainder unrounded until the complete-pour count is determined. T48 displays the final pour cost to cents; T49 displays the percentage to one decimal place. The whole-pour model absorbs the remainder once.
Choose what happens to the remainder
Continuous allocation prices the selected pour from the usable volume and leaves the remainder as usable stock. Whole-pour allocation assigns the full container price to complete pours and treats the final remainder as unavailable for that service calculation. The article example uses whole-pour because the service record is based on complete pours.
| Policy | Result for the example | Remainder status | Interpretation |
|---|---|---|---|
| Continuous | $24 × 40 ÷ 675 + $0.20 = $1.6222… | 35 mL remains in usable stock | Cost follows liquid volume consumed. |
| Whole-pour | $24 ÷ 16 + $0.20 = $1.70 | 35 mL is absorbed once | Cost follows 16 complete service pours. |
| No separate loss | Use only when volume is already usable | No extra reduction | Do not re-enter an already removed loss. |
| Mixer cost | Add the entered cost per pour | Not part of container allocation | Packaging, fees, and operating costs remain outside. |
Check the pour-cost percentage on the same serving
T49 divides the chosen pour cost by the beverage selling price and multiplies by 100. If the drink is sold in a different size, uses a different mixer, or has a different price, calculate that serving separately. The percentage describes the entered cost scope and does not include costs the form does not ask for.
Use the displayed cost for the price check
The whole-pour result is $1.70 per pour. Dividing $1.70 by the $8.00 selling price gives 21.25%, which the calculator displays as 21.3%. Keep the unrounded percentage for interpretation until display.
Beverage pour formula reference
Use positive matching volumes, a loss below 100%, and a declared allocation model. Whole-pour allocation requires at least one complete pour.
| Task | Equation | Condition |
|---|---|---|
| Usable volume | Container volume × (1 − loss ÷ 100) | Loss is separately measured and below 100%. |
| Theoretical pours | Usable volume ÷ pour volume | Volume units match. |
| Complete pours | floor(usable volume ÷ pour volume) | Whole-pour model requires at least one complete pour. |
| Continuous beverage cost | Container price × pour volume ÷ usable volume | Remainder remains usable stock. |
| Whole-pour beverage cost | Container price ÷ complete pours | Remainder is absorbed once. |
| Pour cost percentage | Pour cost ÷ selling price × 100 | Selling price is nonzero and matches the pour. |
Keep the service model with the beverage record
Record container product, volume unit, measured loss method, pour size, allocation model, mixer amount, and price basis. When the pour size or service policy changes, rerun the calculation rather than carrying the old cost percentage forward.
State the remainder policy with the pour cost
A beverage pour cost is only reproducible when the volume units, measured loss, allocation model, mixer scope, and selling price are explicit. Continuous allocation and whole-pour allocation can produce different results because they treat the remainder differently. Keep the selected model with the beverage record, then compare the resulting pour cost with the price for the same pour size.
