Meal Prep Container Portion Calculator
Macro calculators assume one meal - batch cooking means splitting one big cook into several containers evenly. Enter your total by weight or by macros, pick the number of containers, and get an exact even split with no container shortchanged. Nothing uploaded.

How even-split portioning works with remainders
When dividing a recipe across containers, perfect division isn't always possible. This calculator divides the total as evenly as possible, then pushes any remainder to the last container. For example, 500 grams across 3 containers yields 166g, 166g, and 168g. The same logic applies to macros and calories - protein, carbs, and fat are split independently so their totals match your original recipe exactly. This method ensures you use all ingredients with no loss or double-counting, which is crucial for accurate nutrition tracking across meal-prepped portions.
Using this for nutrition and diet tracking
If you're tracking protein intake, calories, or macros across multiple meals, entering your recipe's total nutrients and number of containers gives you the per-portion breakdown. The last container will be slightly larger by remainder amount, but across a week of meal prep, this difference averages out. For accurate tracking, weigh your containers when dividing the food - the calculator assumes perfect mathematical division, but real-world variation in portion sizes is normal.
FAQ
Why does the last container have a different amount than the others?
To ensure the sum of all portions equals your original total exactly, any remainder is added to the last container. For example, 1000 calories split into 3 meals is 333, 333, and 334. This prevents loss of calories or macros due to rounding.
Can I use this for weight-based portioning too?
Yes. The calculator works with any unit - grams, ounces, calories, grams of protein, etc. Enter your total weight or nutrients and divide by number of containers to get per-portion values. Weigh your actual containers after dividing to verify real-world portions match these calculations.
Do I need to enter every macro, or can I skip some?
You can enter just weight, or weight plus macros, or just calories - any combination. The calculator splits whatever fields you provide and ignores empty fields. This flexibility lets you track at the level of detail you prefer.
