Estimate how much food your household needs before shopping, batch cooking or preparing meals for the week. The Family Meal Quantity Planner converts people, planning days, meals per day and portion size into a total cooked-food target. Optional yield, package and price inputs help turn that serving plan into a more practical purchase estimate.
Use this calculator alongside the Velora Foods Meal Planning Tools collection to plan quantities and keep your shopping estimates consistent.
Results are estimates based on the values you enter. Nothing you type is sent to or stored on our servers.
What the Family Meal Quantity Planner Calculates
The calculator separates the number of portions from the mass required to prepare them. First, it calculates how many individual meal portions are planned. It then multiplies that count by the cooked portion weight and adds an optional preparation allowance. If you enter cooking and trimming yields, it estimates the raw ingredient mass needed to deliver that cooked target.
- Total planned portions for the household and selected number of days.
- Cooked food target, including the preparation allowance.
- Estimated raw purchase weight after cooking and trimming losses.
- Whole-package quantities when a package size is supplied.
- Estimated ingredient cost and cost per planned portion when a price is entered.
How to Use the Calculator
Enter household size and planning period
Enter the number of people who will eat the planned meals, then choose the number of days covered by the plan. The calculator accepts 1 to 500 people and 1 to 31 days. For a one-day family dinner, use one day; for a weekly plan, use seven days.
Set meals per person per day
Enter how many meals each person is expected to eat from the batch each day. Use two if the prepared food covers two meals per person per day, or one if it covers only a single meal. Do not enter the total number of meals for the entire household in this field; the calculator multiplies this value by people and days.
Choose portion weight and unit
Enter the cooked portion weight for one person. Select grams, kilograms, ounces or pounds from the unit list. Use the same portion basis throughout a plan. A cooked portion weight should represent the prepared food served to one person, not the raw weight purchased before cooking.
Add allowance and yield assumptions
The extra preparation allowance is an optional percentage added to the cooked target. Cooking yield represents the share of raw, trimmed ingredient mass remaining after cooking. Usable trimming yield represents the share of purchased ingredient mass remaining after trimming or cleaning. Leave either yield blank to use 100%, which means no loss is assumed at that stage. Enter measured values from your own recipe or kitchen records whenever possible.
Estimate packages and cost
For package planning, enter the net package size in grams. The calculator rounds the raw purchase requirement upward to a whole number of packages and reports the estimated remainder. To estimate cost, enter the purchase price per kilogram and choose a currency. Cost is based on the rounded package quantity when package size is supplied; otherwise it uses the unrounded purchase estimate.
Formula and Calculation Method
The model uses a sequence of transparent mass-balance calculations. Let P be the number of people, D the number of days, M the meals per person per day, W the cooked portion mass in grams, B the preparation allowance as a percentage, Yc the cooking yield as a fraction, and Yt the usable trimming yield as a fraction.
1. Planned portion count
N = P × D × M. This gives the total number of individual portions covered by the plan.
2. Cooked food requirement
Base cooked mass = N × W. The allowance-adjusted cooked target is C = N × W × (1 + B/100). The allowance is applied to cooked demand before converting that target into a raw purchase quantity.
3. Raw purchase requirement
Raw purchase mass = C ÷ Yc ÷ Yt. Enter yields as percentages from 1% to 100%. For example, a 75% cooking yield is represented by 0.75 in the calculation. A lower yield increases the raw amount required to produce the same cooked quantity.
4. Package count and estimated cost
If package size S is entered in grams, packages required = ceiling(raw purchase mass ÷ S). Rounded purchase mass equals package count multiplied by package size. Estimated cost equals purchase mass in kilograms multiplied by the entered price per kilogram.
Worked Example: A Family of Four
Suppose four people are planning three meals, with a cooked portion of 350 g per person and a 5% allowance. The plan contains 4 × 3 = 12 portions. Base cooked mass is 12 × 350 g = 4,200 g. The 5% allowance adds 210 g, giving a cooked target of 4,410 g, or 4.41 kg.
If the cooking yield and trimming yield are both left at 100%, the raw purchase estimate remains 4.41 kg. If you enter a 75% cooking yield and a 90% usable trimming yield, the raw purchase estimate increases to about 6.53 kg. The higher value reflects the assumed preparation losses; it is not a universal yield for every food.
Understanding the Results
- Cooked food target is the amount the plan aims to serve after preparation, including the allowance.
- Raw purchase requirement estimates the ingredient mass needed before the entered cooking and trimming losses.
- Package count is rounded upward, so the purchased amount may exceed the calculated requirement.
- Estimated remainder is the difference between the rounded package quantity and the calculated raw requirement.
- Estimated cost is an arithmetic estimate only; it does not include taxes, delivery charges, discounts or price changes unless you include them in the entered price.
Accuracy, Food Safety and Practical Limitations
The result depends on the portion size, yield percentages and preparation allowance you enter. Food type, cut, recipe, cooking method, moisture loss, trimming technique and supplier specifications can all affect actual yield. Do not apply one yield assumption to every ingredient. Where possible, weigh a representative raw batch and its prepared output, then calculate the yield from your own records.
This calculator estimates quantities; it does not determine whether a meal is nutritionally balanced or suitable for a particular person. It also does not replace food-safety controls. Follow local food-safety guidance for cooking temperatures, cooling, storage, reheating, allergen handling and use-by dates. Keep raw and cooked weights clearly distinguished when recording recipes.
Frequently Asked Questions
Can I use the planner for a full week?
Yes. Set the planning period to seven days and enter the number of meals each person will receive from the batch per day. If you are planning only selected dinners or lunches, enter only those meals rather than all meals eaten in the week.
What happens if I leave the yield fields blank?
Blank cooking and trimming yield fields default to 100%. This assumes no mass loss at that stage, so the raw purchase estimate will not increase for that step. Enter realistic measured yields when you want a more useful purchase estimate.
Why is the package quantity higher than the raw requirement?
The planner rounds the package count upward because most packaged ingredients are purchased in whole packs. The extra amount is shown as an estimated remainder. If you buy loose-weight ingredients, leave package size blank.
Can I enter pounds or ounces?
Yes. Select ounces or pounds as the portion unit. The calculator converts the entered portion mass to grams internally, while the final food and purchase quantities are reported in grams and kilograms.
Does the calculator save household information?
The calculator performs its calculations in your browser. Do not enter personal or sensitive information; household size and meal quantities are all that is needed for the estimate.

Calculation Notes and Disclaimer
The equations use mass conservation with user-supplied yield fractions and an optional allowance. All conversions are arithmetic estimates. Results should be checked against actual recipes, measured batch yields, package labels and current supplier prices before placing a large order.
