About this Meal Prep Cost Calculator
Meal prep usually saves money, but the real cost includes more than groceries. Containers, wasted ingredients, and your prep time can change the cost per serving.
Who this calculator is for
- Households planning weekly grocery budgets.
- Meal preppers comparing homemade meals with takeout or prepared meals.
- Fitness and nutrition planners estimating cost per serving.
When to use it

- Review total batch cost and cost per serving.
Key assumptions
- Waste percent is applied to ingredient cost, not containers or labor.

How this calculator works
Adjusted food cost = ingredient cost x (1 + waste percent). Total batch cost = adjusted food cost + container cost per serving x servings + prep hours x hourly value. Cost per serving = total batch cost / servings.
Adjusted food cost = ingredient cost * (1 + waste percent / 100). Labor cost = prep hours * hourly value. Total batch cost = adjusted food cost + container cost per serving * servings + labor cost. Cost per serving = total batch cost / servings.
