Ghee Yield Calculator

Ghee weight and yield from butter weight, butter fat, ghee fat, and process loss.

What it does

Butter is an emulsion of fat, water, and milk solids. Heating it drives off the water, browns and separates the solids, and leaves the fat. Ghee is that fat, which is why a kilogram of butter never becomes a kilogram of ghee.

The estimate here is a fat balance. All the fat that enters in the butter can stay in the ghee, minus whatever sticks to the residue or burns. Water and milk solids leave entirely. If butter is 81% fat and ghee is 99.6% fat, then each gram of butter fat ends up in slightly more than one gram of ghee.

The numbers default to common values. Salted butter in the USDA database runs 81.1% fat. Codex Alimentarius requires at least 80% milk fat in butter and at least 99.6% milk fat in ghee. Your brand may sit a little above or below, so check the label when the exact amount matters.

A small process loss covers ghee that stays with the residue, splashes, or browns onto the pan. Two percent is a reasonable home kitchen assumption. Commercial creamery butter methods report fat recovery around 88 to 92%, while small batch and indigenous methods run lower, so treat the loss field as your own dial.

The result is the weight of finished ghee, not its volume. Ghee is less dense than water, so a 399 g jar is roughly 434 mL. If you sell or label by volume, measure the filled jar rather than converting weight directly.

Starting with cultured or European style butter changes the flavor, not the fat balance. The same weight of fat leaves the same weight of ghee. What changes is how much water and solids you start with, which is why a higher fat butter gives more ghee per kilogram.

How to use

1. Pick Metric or Imperial for the butter weight.
2. Enter how much butter you plan to clarify.
3. Enter the butter fat percentage from the label or a reference.
4. Leave ghee fat at 99.6% unless your product states otherwise.
5. Set the process loss for your kitchen, usually 1 to 3%.
6. Read the ghee weight first, then the yield and the weight removed.

Formula

butter weight

Starting butter mass in grams or pounds.

butter fat

Fat fraction of the butter, such as 81.1%.

ghee fat

Fat fraction of the finished ghee, such as 99.6%.

loss

Percent of fat left behind in residue or lost in handling.

Fat is conserved through the process except for the loss term. Water and milk solids leave as steam, foam, and browned residue. A higher butter fat percentage or a lower process loss raises the yield. The formula does not account for added salt, which stays in the residue, or for flavoring added after clarification.

Limits

• Assumes all butter fat either becomes ghee or the stated loss; it ignores fat left in foam on the walls.
• Uses the fat percentages you enter, which may differ from your actual butter and finished ghee.
• Does not predict flavor, color, or whether the milk solids brown enough before the water is gone.
• Volume is not calculated, because ghee density changes with temperature.

Common mistakes

• Expecting a kilogram of butter to yield a kilogram of ghee.
• Using the net weight of salted butter without accounting for the salt and water.
• Setting butter fat at 100% and overstating the yield.
• Skimming too early and leaving fat in the residue.
• Judging doneness by time instead of by the sound and color of the solids.
