Meal Prep Portioning Calculator

Choose what you're dividing by, enter your batch total and container count, to see the amount to put in each container.

How this works

Meal prep portioning is simple division: whatever total amount you cooked — measured by weight, calories, or servings — gets divided evenly across however many containers you're filling. This calculator handles that division for whichever unit you're measuring by.

Source: Standard batch-portioning arithmetic (total ÷ number of containers), the same method used in commercial and home meal-prep planning.

Frequently asked questions

Can I portion by weight instead of calories?

Yes — choose whichever measurement you have for your batch (total weight in ounces, total calories, or total servings) and the calculator divides that figure evenly across your container count.

Does this account for container size?

No — this calculator tells you how much of your batch goes in each container by weight, calories, or servings; it doesn't check whether that amount physically fits your specific container size.

How many meal-prep containers do I need for a week of lunches?

For one lunch a day, 5 containers covers a workweek and 7 covers every day — enter your container count here to see how much of your batch goes in each.
