Cooked Broccoli Portion and Yield Calculator
A cooked batch is easier to divide when you weigh it first. Enter the prepared raw weight and the finished cooked weight, then choose equal servings or a portion weight. The calculator uses your batch measurements to show portions, leftovers and the weight change during cooking.
Portions and yield use your entered weights. Weight-ounce conversions follow NIST mass conversion factors.
Divide your actual cooked batch
Weigh the prepared broccoli before cooking and the drained batch afterward. The filled amounts are a worked example, not a fixed cooking-loss rule.

Weigh drained broccoli without the pot or bowl.

Weight yield is not nutrient retention. Water gain or loss does not establish how much protein, vitamins or energy remained.

What does this calculator work out?
This tool answers a kitchen question: how much of this finished broccoli belongs in each container or on each plate? It does not calculate calories or decide how much someone should eat. Your portion size is a choice, and the calculator handles the division.
The raw and cooked weights also give a measured yield ratio. This describes this particular batch, prepared and drained in this particular way. It is useful for repeating a meal, but it is not a standard shrinkage rate for every broccoli head or cooking method.
Weigh the same usable broccoli before and after cooking
Start with trimmed, usable broccoli. Remove the parts you are not cooking, wash the vegetable and let surface water drain before taking the starting weight. Weighing a whole untrimmed head and comparing it with cooked florets mixes trimming loss with cooking change.
For the finished weight, put an empty bowl on the scale, tare it to zero, and add the cooked broccoli. Use the food weight without the bowl, basket or tray. Drain in the same way each time. A puddle of cooking water changes the result even though it is not another floret.
Choose equal servings or a fixed portion weight
Use equal servings when you have a known number of plates or lunch boxes. Divide the entire cooked weight by that number. This mode shares the batch mathematically; weigh the food into each container if you want those portions to match the result closely.
Use a fixed portion weight when your containers need a particular amount. The calculator counts whole portions and leaves any remainder separate. It does not quietly round a partial portion up to another full meal. You can combine that remainder with another side or divide it among the finished plates.
Worked example: one batch, two ways to divide it
Suppose your trimmed raw broccoli weighs 600 g and your cooked, drained batch weighs 510 g. These are example measurements, not a promised cooking result. Dividing 510 by 600 gives a yield ratio of 0.85, or 85%. The cooked batch weighs 15% less.
If you choose four equal servings, each receives 127.5 g cooked broccoli. If you instead choose 100 g portions, you can fill five complete portions and have 10 g left. Both answers describe the same batch; the difference is the serving rule you selected.
| Choice | Calculation | Result |
|---|---|---|
| Four equal servings | 510 g ÷ 4 | 127.5 g each |
| 100 g fixed portions | Five × 100 g | Five portions and 10 g left |
| Measured yield | 510 g ÷ 600 g | 0.85, or 85% |
How should you read the raw-equivalent result?
Raw equivalent means the share of your starting broccoli associated with one cooked portion. In the four-serving example, each equal serving corresponds to one quarter of the 600 g starting weight, or 150 g raw. That is an accounting relationship within the measured batch.
It is not a statement that 150 g raw broccoli always becomes 127.5 g cooked. A different tray, cut size, draining period or cooking method can produce another ratio. Use a new pair of weights when the process changes rather than carrying the old figure into every recipe.
A weight change is not a nutrient-retention measurement
Broccoli can lose water while roasting or carry more water after cooking and draining. The scale records the resulting food mass. It cannot tell you how much vitamin C, fiber, protein or another nutrient survived the cooking process.
Do not use the yield percentage as a nutrient-retention percentage. For a food log, the broccoli calorie calculator uses a matching food entry and measured amount. For a mixed dish, the recipe calculator accounts for the ingredients added. Neither needs a made-up assumption that weight loss equals calorie loss.
Keep sauces and other ingredients consistent
For a broccoli-only yield, weigh the plain vegetable before adding cheese sauce, butter or oil. Adding a sauce after the starting weigh-in makes the final weight include food that was absent from the raw measurement. The resulting ratio no longer describes broccoli cooking yield alone.
If you want to portion a finished mixed dish, the cooked weight still helps divide the food. Use the recipe calculator for its nutrition. When sharing pieces coated unevenly in sauce, stir or distribute them thoughtfully before weighing portions; equal weight does not automatically mean identical ingredients.
Why do the numbers look unexpected?
A final weight above the starting weight is possible. Check for retained water, additions, an untared container or different ingredients. The tool allows a gain because it is reporting your measurements, rather than forcing every batch into a loss assumption.
If a result seems wildly wrong, check the units first. A number read in ounces must not be entered as grams. Then check that the raw amount excluded trimmings and the cooked amount excluded its vessel. A simple note of the method and weighing stage makes the next comparison more useful.
Frequently asked questions
Can I use this without weighing the raw broccoli?
You can divide a cooked batch by its weight alone with ordinary arithmetic, but a measured raw-to-cooked yield needs both weights. Do not invent the starting amount to obtain a ratio.
Does a smaller cooked portion mean fewer calories?
Not by itself. Water change affects food weight. The food entry, ingredient amounts and preparation matter. Use a matching raw or cooked entry in the calorie calculator instead of converting calories with the yield percentage.
What if there is not enough food for one fixed portion?
The whole-portion count is zero and the batch remains a remainder. Lower the chosen portion weight or use equal servings if you want to share everything. The calculator should not label a smaller portion as a full one.
Can I reuse the ratio when shopping next week?
Use it as your own planning reference for a similar preparation, then check the next batch. Broccoli size, trimming and cooking conditions vary. A measured history is more useful than treating one example as a universal conversion.
Why can the cooked weight be higher than the raw weight?
The tool allows a weight gain because food can retain water or include additions. Check that both weights cover the same usable broccoli and exclude containers. A gain in mass is not evidence that the broccoli gained calories or retained every nutrient.
Can I enter a fractional number of equal portions?
Use a whole number in equal-portion mode, such as four containers. If you want a specific amount rather than a container count, choose Count portions by weight. That mode counts complete portions and reports the remaining cooked food separately.
