Calculate moisture loss from the weight before and after drying, curing or dehydrating.
Usage Tip
Track weight to a target loss rather than guessing by time alone.
What Is Moisture Loss?
Moisture loss – or cooking shrinkage – is the weight food loses during cooking as water and rendered fat cook off. A raw chicken breast can lose a quarter of its weight; a smoked brisket can lose nearly half. For anyone selling food, that shrinkage is the difference between a costed plate and a loss.
yield % = cooked weight ÷ raw weight × 100
The calculator above works both ways: measure actual loss from raw and cooked weights, or estimate the cooked yield before you buy.
Meat Moisture Loss
Meat loses the most, especially fatty, slow-cooked cuts. Typical losses:
| Food | Typical moisture loss |
|---|---|
| Chicken breast | 20–30% |
| Pork butt | 30–40% |
| Brisket | 35–50% |
| Beef (general) | 25–35% |
| Turkey | 25–30% |
| Fish | 10–25% |
| Vegetables | 10–40% |
| Food | Cooked yield |
|---|---|
| Brisket | 50–65% |
| Pork butt | 55–70% |
| Chicken | 70–80% |
| Turkey | 70–75% |
Seafood Moisture Loss
Fish loses less than meat – usually 10–25% – because it has less connective tissue and cooks quickly. Shrimp shrink about 20–25% and curl tightly. Overcooking is the main driver of seafood loss; pull it early to keep more weight and moisture.
Baking Moisture Loss
Bread and baked goods lose moisture as steam during baking – typically 10–20% of the dough weight (this is the “bake loss” bakers track). Lean, crusty breads lose more than enriched, soft ones. Bakers weigh dough in and loaves out to dial in oven time and hydration.
Cooking Method Comparison
How you cook changes the loss as much as what you cook:
| Method | Relative loss | Why |
|---|---|---|
| Smoke | Highest | Long, low – hours of evaporation |
| Roast | Moderate-high | Dry heat, longer times |
| Grill | Moderate-high | High direct heat |
| Fry | Moderate | Fast, but high heat |
| Bake | Lower | Often covered or moister |
BBQ Shrinkage Examples
Low-and-slow barbecue is the shrinkage champion. A 16 lb packer brisket commonly cooks down to 8–10 lb – a 40–50% loss. A 9 lb pork butt yields about 5–6 lb of pulled pork. Competition and catering cooks buy by the cooked pound and work backward, or they run short.
Yield & Cost Planning
Shrinkage drives real food cost. If brisket costs $4/lb raw but yields 55%, the cooked cost is about $7.27/lb ($4 ÷ 0.55) before labour. Caterers and restaurants price from cooked yield, not raw purchase weight – ignoring shrinkage is how a menu quietly loses money.
Commercial Kitchen & Food Service Examples
- Caterer: needs 100 6-oz cooked chicken portions (37.5 lb cooked); at 75% yield, buy 50 lb raw.
- BBQ joint: sells pulled pork by the cooked pound; tracks yield per cook to set portions and price.
- Meal prep: standardises raw-to-cooked ratios so macros on the label match the cooked portion.
- Restaurant: builds plate cost from cooked yield plus trim loss, not sticker price.
Moisture Retention Tips
- Cook to temperature, not time – overcooking is the biggest cause of loss.
- Brine or marinate to hold more water (see the linked calculators).
- Rest meat so juices redistribute instead of running out.
- Lower, gentler heat loses less than blasting high heat.
- Cook fattier cuts to render gradually; don’t rush them.
Common Shrinkage Mistakes
- Pricing or portioning from raw weight instead of cooked yield.
- Assuming one shrinkage number fits every cut and method.
- Overcooking, then wondering where the weight went.
- Ignoring carryover cooking during the rest.
- Not tracking your own yields – every oven and cut differs.
Frequently Asked Questions
How do you calculate moisture loss?
Subtract cooked weight from raw weight, divide by raw weight, and multiply by 100. Yield is simply cooked divided by raw.
How much weight does meat lose when cooked?
Usually 20–50% depending on the cut and method – chicken breast 20–30%, pork butt 30–40%, brisket 35–50%.
How much does a brisket shrink?
About 35–50%. A 16 lb raw brisket typically finishes around 8–10 lb.
How do I figure out raw weight from cooked?
Divide the cooked weight you need by the yield. For 20 lb cooked at 60% yield, buy about 33 lb raw.
Does cooking method affect shrinkage?
Yes – smoking and roasting lose the most, baking and gentle methods the least, for the same food.
How do I reduce moisture loss?
Cook to temperature not time, brine or marinate, use gentler heat, and rest the meat before slicing.
