Milk Waste Calculator

Litres bought against litres that reached a cup. What goes down the sink every week and every year.

Milk bought per week

All of it, dairy and alternatives, from the invoices.

Milk drinks sold per week

From the till: lattes, flat whites, cappuccinos, hot chocolates.

Milk that ends up in the cup

Not what you steam. What fits in the cup. 190 for a 12 oz latte.

Dairy price per litre

Share of drinks on oat / almond / soy

Alternative milk price per litre

How this is calculated

Litres used = drinks × ml in the cup ÷ 1000. Waste = litres bought − litres used.

Blended price = dairy × (1 − alt share) + alternative × alt share. Weekly cost = waste × blended price.

Under 10% is a tight bar. 10 to 20% is normal and fixable with smaller jugs. Over 20% is a training problem.

Prices are before GST/HST. Add tax on top of the price shown, never inside your margin. Estimates, not advice.
