How Much Does Meal Prepping Actually Save? (We Did the Math)

By Sarah Mitchellยทยท5 min read

Meal prepping has exploded in popularity over the past decade, promoted as a way to save money, eat healthier, and reclaim time during busy weekdays. But does meal prepping actually save significant money, or is it just an Instagram trend? We ran the numbers using real grocery prices and restaurant costs, and the savings are substantial โ€” potentially thousands of dollars per year depending on how often you currently eat out.

The True Cost of Eating Out

According to the Bureau of Labor Statistics, the average American household spends $3,639 per year on food away from home, which includes restaurants, fast food, delivery, and cafeteria meals. For a single person eating lunch and dinner out 5 days per week, the math is even more striking.

A typical fast-casual lunch costs $12-15 including a drink. Dinner at a casual restaurant averages $15-25 per person. Delivery adds $5-10 in fees and tips per order. Even fast food averages $9-12 per meal once you add a drink and side.

If you eat lunch out 5 days per week at $13 average and dinner out 3 times per week at $18 average, that is $65 per week for lunches and $54 for dinners โ€” $119 per week or $6,188 per year just for those meals.

The True Cost of Meal Prepping

Meal prep costs depend heavily on what you are cooking, but here are realistic per-serving costs for common meal prep staples based on current grocery prices. Chicken breast with rice and roasted vegetables costs approximately $2.50-3.50 per serving. Ground turkey chili with beans runs about $2.00-2.75. Pasta with meat sauce and a side salad costs $1.75-2.50. Egg muffins with vegetables for breakfast come in at $1.00-1.50.

Average meal prep cost per serving across a variety of recipes: $2.50-4.00. Calculate your specific recipes using our [Meal Prep Cost Calculator](/calculators/meal-prep-cost-calculator) for exact per-serving breakdowns.

The Savings Breakdown

Replacing the same 5 lunches and 3 dinners from our earlier example with meal prep at an average of $3.50 per serving saves significant money. Meal prep lunches: 5 ร— $3.50 = $17.50 per week versus $65 eating out. Meal prep dinners: 3 ร— $3.50 = $10.50 per week versus $54 eating out.

Weekly savings: $91 per week. Monthly savings: $394 per month. Annual savings: $4,732 per year.

Even if you only replace weekday lunches with meal prep and continue dining out for dinner, you save $47.50 per week or $2,470 per year. That is enough for a vacation, a significant emergency fund contribution, or 6 months of extra debt payments.

Pair this savings with a comprehensive spending plan from our [Budget Calculator](/calculators/budget-calculator) to see how meal prep transforms your overall financial picture.

Factoring In Hidden Costs

Fair meal prep cost analysis should include some hidden costs that pure per-serving calculations miss. Containers cost $15-30 initially for a quality set of glass or BPA-free plastic containers that last years. Spices and pantry staples โ€” an initial stock of basic spices, oils, and seasonings runs $30-50 but lasts months. Energy costs for cooking add roughly $0.15-0.25 per meal for electricity or gas. Time cost is the most subjective factor: a typical meal prep session takes 2-3 hours to prepare 10-15 meals.

Even accounting for all hidden costs, the per-serving price of meal prep remains dramatically lower than eating out. The time investment of 2-3 hours produces meals for an entire week, saving you the daily time spent deciding what to eat, traveling to restaurants, and waiting for food.

Budget Meal Prep Strategies

To maximize savings, buy proteins in bulk when on sale and freeze them. Chicken thighs ($1.50-2.50/lb) are more affordable and flavorful than breasts ($3.50-5.00/lb). Use our [Grocery Budget Calculator](/calculators/grocery-budget-calculator) to set your overall food spending target.

Rice, beans, oats, and pasta are the cheapest calorie sources and should form the base of budget meal prep. Buy frozen vegetables โ€” they are flash-frozen at peak ripeness, often more nutritious than out-of-season fresh produce, and cost 50-60% less. Cook in batch โ€” making a large pot of chili costs barely more than making a small one but yields 8-10 servings instead of 2-3.

Plan meals around weekly grocery sales. Check your store's circular before deciding what to prep. Base your protein choices on what is on sale that week rather than following rigid recipes.

The Nutritional Bonus

Beyond saving money, meal prepping gives you complete control over portion sizes, macronutrients, sodium, and ingredient quality โ€” things you have zero control over when eating out. Restaurant meals contain an average of 1,200 calories per plate and significantly more sodium, sugar, and fat than home-cooked equivalents.

When you meal prep, you decide exactly how much rice goes in each container, how much oil is used in cooking, and whether vegetables or fries accompany your protein. This nutritional control is why meal prepping is popular among fitness enthusiasts โ€” it makes hitting macro targets effortless.

Getting Started: Your First Meal Prep

If you have never meal prepped before, start simple with just 5 identical lunches for the work week. Pick one protein (chicken thighs), one carb (rice), and one vegetable (broccoli). Season simply with salt, pepper, garlic powder, and olive oil. Cook everything in bulk, portion into 5 containers, and refrigerate.

Total cost for 5 chicken and rice lunches: approximately $12-15. Total time: about 1 hour including cleanup. Cost per meal: $2.40-3.00.

Compare that to 5 lunches out at $13 each ($65 total), and your first week of meal prepping saves you $50 with about an hour of effort. That is a $50/hour return on your time โ€” better than most side hustles.

Once you are comfortable with the routine, expand to 2-3 different recipes per week, add breakfasts, and experiment with freezer-friendly meals that extend your prep to 2 weeks. The financial and health benefits compound over time, making meal prepping one of the highest-impact habits you can build.
