Weekly Meal Prep Estimator

Before the grocery run: how many eaters, how many days, and how many meals you batch per day. Get container count, protein to buy, rice and veg scale, and a realistic prep-time range.

Portion size

Main protein

Sunday prep shopping scale

5 containers

Chicken / turkey breast: 2.1 lb (33 oz raw)

2.5 cups dry rice (≈ 8 cups cooked)

5 cups vegetables (raw chop volume)

Plan mostly 3-cup (24 oz) containers; keep a few 16 oz for snacks

Active kitchen time: under 1 hour (batching helps)

Per-container breakdown: meal prep portion calculator. Starch alternatives: rice · pasta.

Assumes similar bowls each day with rice as the default starch. Mixed proteins average shopping weight — buy per the heaviest day if you rotate cuts.

How to read the numbers

Totals assume similar bowls all week — rotate sauces or vegetables without changing the protein math much. Buy slightly extra if you snack from the batch. Container hints follow standard 16 oz and 24 oz meal-prep lids sold in US stores.

FAQ

How many meal-prep containers do I need for the week?
Multiply people × days you want covered × how many meals per day you prep (usually 1 for lunch-only, or 2 if lunch and dinner). One person, five workdays, lunch only = five containers.
Why does the shopping list assume rice?
Rice is a common batch-cook starch for bowls. Use the rice or pasta portion calculators if you swap starches — protein and veg totals still help for shopping.
Is the prep time accurate?
It is an active-kitchen estimate that improves when you batch chop and cook — not calendar time with oven waiting. First-time preppers often take longer until their assembly line is set.
Can two people share one prep day?
Enter the number of people eating the prep. The tool scales raw protein and starch for everyone; you can split cooking tasks, but shopping totals are for the household.
