About this calculator

Calculate how much liquor cost is lost or saved based on actual pour size versus your standard recipe pour.

What is an acceptable pour variance?

Most bars aim for pours within 0.1-0.2 oz of the standard recipe. Larger variances consistently add up to significant cost leakage over time.

How can I reduce overpouring?

Use jiggers or metered pour spouts, train staff on standard recipes, and periodically audit pour consistency during service.
