How the Meal Prep Cost Calculator Works
This calculator helps you determine the true cost of meal prepping by accounting for proportional ingredient usage. Instead of counting the full package price, you specify how much of each ingredient you actually use, so you get an accurate cost per serving.
Ingredient Cost = Total Price × (Used Amount ÷ Total Amount)
Cost per Serving = Sum of All Ingredient Costs ÷ (Meals × Servings per Meal)

Frequently Asked Questions
How much does meal prepping actually save?
The average meal prep costs $3-5 per serving, while the average restaurant meal costs $13-15 and delivery averages $15-20 with fees and tips. If you meal prep lunch and dinner 5 days a week instead of eating out, you can save $150-250 per week or $600-1,000 per month. Even replacing just 5 meals per week with meal prep saves $40-75 weekly, or roughly $2,000-4,000 per year.
What are the cheapest meal prep proteins?
The most budget-friendly proteins per gram of protein are eggs ($0.08/10g protein), canned tuna ($0.10/10g), dried lentils ($0.06/10g), chicken thighs ($0.10/10g), and cottage cheese ($0.12/10g). Buying whole chickens and breaking them down yourself saves 40-50% compared to boneless skinless breasts. Buying proteins in bulk when they are on sale and freezing them is another significant cost-saving strategy.
How long do meal prepped foods last?
Most meal prepped foods last 3-5 days in the refrigerator when stored in airtight containers. Cooked proteins, grains, and roasted vegetables stay fresh for about 4 days. Some meals like soups, stews, and chili actually improve in flavor over 2-3 days. For longer storage, freeze meal prep containers for up to 3 months. Label everything with the date and contents for easy rotation.
