The PreciEat Raw to Cooked Weight Calculator estimates how much food will weigh after cooking by combining raw weight, food type, cooking method, and servings. It is a fast starting point for meal prep, macro tracking, and portion planning when you want a practical cooked-yield estimate instead of a generic shrinkage chart.
Inputs
Choose the food, cooking method, raw weight, and servings to estimate cooked yield.
Method choices update automatically when you change the food type.
Results
Your cooked-weight estimate appears here after you calculate.
Select your inputs and click Calculate yield to see the cooked estimate.

Why this calculator exists
Raw ingredients do not all change weight the same way. Chicken, beef, pork, fish, rice, pasta, beans, and vegetables each behave differently because they lose or absorb water at different rates. The calculator gives you a realistic estimate that is easier to use than mental math when you are batching meals or dividing food into portions.
What the calculator estimates
The PreciEat Raw to Cooked Weight Calculator estimates cooked weight, yield percentage, weight change, and per-serving weight based on the food type and cooking method you choose.
- Estimated cooked weight in grams, ounces, or pounds
- Yield percentage and cooked-to-raw ratio
- Weight change so you can see shrinkage or gain at a glance
- Per-serving estimate for meal prep and macro tracking
How to use it
- Select the food type that matches your ingredient as closely as possible.
- Choose the cooking method you plan to use.
- Enter the raw weight and pick the unit that matches your scale.
- Add the number of servings, then click Calculate yield.
How to interpret the result
The estimate is most useful as a planning number. If the result is lower than the raw weight, the food has likely lost moisture. If the result is higher, the food has absorbed water during cooking, which is common with rice, pasta, beans, and some vegetables.
For the cleanest real-world reading, weigh the food after it has rested briefly. Surface steam can add noise to an immediate post-cook measurement, especially with rice and protein dishes.
Typical yield patterns
| Food group | Common cooked-weight pattern | What usually drives it |
|---|---|---|
| Chicken, beef, pork, fish | Usually weigh less after cooking | Moisture loss and fat rendering |
| Rice and pasta | Usually weigh more after cooking | Water absorption during cooking |
| Beans and lentils | Usually weigh more after cooking | Soaking and simmering absorption |
| Vegetables | Can go either direction | Water loss, steam retention, and cut size |
FAQ
Is this calculator exact?
No. It is a practical estimate based on common cooking behavior. Real results vary by cut, pan size, heat level, and how long the food is cooked.
Why does rice or pasta gain weight?
Rice and pasta absorb water during cooking, so the cooked portion usually weighs more than the dry raw ingredient.
Can I use this for meal prep?
Yes. The calculator is especially useful for portion planning, batch cooking, and splitting a cooked batch into evenly sized servings.
Should I weigh before or after cooking?
Weigh before cooking if you want a raw-to-cooked estimate. Weigh after cooking if you want to verify the final yield for a finished batch.
Does the cooking method matter?
Yes. Different methods change how much water stays in the food or leaves it, so roast, grill, steam, boil, and simmer can produce very different results.
