Ice Cream Overrun Calculator
Overrun is the air whipped into ice cream as it churns, and it changes everything from texture to yield. Measure yours by weighing a cup of mix and the same cup of ice cream, or from volumes.
How to use it
- Choose to measure by weight (most accurate) or by volume.
- Weigh a cup of the liquid mix and the same cup filled level with fresh ice cream, or enter the volumes.
- Compare the overrun with the ranges for gelato, homemade and store-bought ice cream.
How it works
By weight: overrun = (weight of mix − weight of the same volume of ice cream) ÷ weight of ice cream × 100. By volume: (ice cream volume − mix volume) ÷ mix volume × 100.
Gelato runs about 20 to 35%, homemade ice cream 20 to 40%, premium store-bought 25 to 50% and economy brands up to 100%.
Assumptions and limits
- Measure right after churning, before the ice cream hardens or melts.
- Use the same container for both weights.
Tips
- Less air means denser, richer ice cream; churning colder and faster adds more.
- Weigh pints of store-bought ice cream: heavier pints have less air.
- Track overrun when you tune a recipe; it explains texture changes.

Questions
What is ice cream overrun?
The increase in volume from air churned into the mix, as a percentage. 50% overrun means 1 quart of mix makes 1½ quarts.
What overrun does homemade ice cream have?
Usually 20 to 40% from home machines.
How much air is in store-bought ice cream?
Premium brands about 25 to 50%; economy brands can reach 100%.
How do I reduce overrun?
Churn a little less long, or use a machine with a slower dasher; gelato machines whip in less air.
