What's the Real Cost Difference Between Cooking at Home and Buying Prepared Meals?
Updated July 10, 2026 · SmartRates Editorial Team
⚡ In short
The Bureau of Labor Statistics' Consumer Expenditure Survey and CPI data track food-at-home and food-away-from-home as separate categories, and food-away-from-home (including restaurant meals and prepared food) has generally carried a materially higher per-meal cost than grocery-based cooking, though the specific gap depends on the grocery items chosen, portion size, and which prepared-food category (fast food, sit-down restaurant, meal-kit service, or grocery deli) is being compared.
📌 Key facts
- The BLS tracks food-at-home and food-away-from-home as separate CPI categories, which historically show different price levels and inflation rates
- A meal-kit delivery service is priced between grocery cooking and restaurant dining in most cost comparisons, since it includes pre-portioned ingredients plus a delivery and service fee
- The comparison depends heavily on which specific grocery items and which specific prepared-food category are being compared
- Beyond ingredient cost, cooking at home also involves time, and prepared food often trades a cost premium for reduced preparation time

How the BLS tracks these two categories separately
The Consumer Price Index separately tracks 'food at home' (groceries) and 'food away from home' (restaurants, prepared meals, delivery), and the BLS Consumer Expenditure Survey publishes data on how much households spend across each category — this separation is what makes a data-based comparison between the two possible, rather than relying on a single combined food category.
Why the per-meal cost of groceries is usually lower
A grocery-based meal's cost generally reflects only the raw ingredient cost, without the labor, overhead, and profit margin built into a restaurant or prepared-food price — this structural difference is a primary reason grocery-based cooking has historically shown a lower per-meal cost across most comparisons, though the exact gap varies by the specific meal and ingredients involved.
Where meal-kit services fall in the comparison
A meal-kit delivery service — pre-portioned ingredients delivered with a recipe — is commonly priced between straight grocery shopping and restaurant dining, since the service includes a convenience premium (portioning, recipe selection, delivery) on top of the underlying ingredient cost, without the full labor and overhead of a restaurant meal.
How fast food compares to sit-down restaurant dining
Within the food-away-from-home category, fast food and quick-service dining generally carry a lower per-meal cost than full-service, sit-down restaurant dining, reflecting differences in labor cost, overhead, and service level — meaning 'restaurant food' isn't a single price point but spans a range depending on the specific dining format.
How grocery deli and prepared sections fit in
Many grocery stores also sell prepared or ready-to-eat food within the store itself — a rotisserie chicken, a deli sandwich, a hot bar item — which occupies a middle ground in the comparison, typically priced above cooking the equivalent meal from raw ingredients but below a comparable restaurant meal.
Why portion size and ingredient choice change the comparison
The specific ingredients chosen for home cooking significantly affect the comparison — a meal built around basic staples (rice, beans, seasonal vegetables) costs less per serving than one built around premium or specialty ingredients, meaning the grocery-cooking side of the comparison isn't a single fixed price point any more than the prepared-food side is.
Time as a factor separate from dollar cost
Cooking at home generally requires more time — shopping, preparation, cooking, and cleanup — than picking up or ordering prepared food, which is a separate consideration from the dollar-cost comparison itself, since the value placed on that time varies by individual circumstances and isn't captured in a pure ingredient-cost comparison.
How food waste affects the true cost of cooking at home
Grocery-based cooking can involve unused portions of purchased ingredients that go to waste, which increases the effective per-meal cost above the amount reflected in a receipt total divided by meals prepared — this is a cost factor sometimes underweighted in a simple grocery-versus-restaurant price comparison.
Where to check current category-level price data
The BLS publishes both the food-at-home and food-away-from-home CPI components on a monthly basis, along with the broader Consumer Expenditure Survey data on category-level household spending, providing an official, updated data source for comparing how these two categories are trending relative to each other over time.
How meal planning and batch cooking affect the per-meal cost
Preparing a larger batch of a single recipe and portioning it into multiple meals is a commonly described way to reduce the per-meal cost of home cooking further, since some fixed costs — active cooking time and certain recipe ingredients — are spread across more servings, distinct from cooking a single-serving meal from scratch each time.
How delivery fees change the prepared-food comparison
Ordering prepared food through a third-party delivery platform commonly adds delivery and service fees on top of the menu price itself, which further widens the per-meal cost gap compared to either cooking at home or picking up the same prepared food directly without using a delivery service.
Frequently Asked Questions
Is home cooking always cheaper per meal than restaurant food?+
In most published cost comparisons, yes on average, though the specific gap depends heavily on the ingredients chosen and which prepared-food category (fast food, sit-down dining, meal-kit) is used for the comparison.
Are meal-kit services cheaper than restaurants?+
Generally yes, meal-kits are commonly priced between grocery cooking and restaurant dining, since they include a convenience premium over raw grocery shopping but not the full overhead of a restaurant.
Does the BLS track restaurant and grocery prices separately?+
Yes — food-at-home and food-away-from-home are tracked as distinct CPI categories, which is what makes an official data-based comparison possible.
Does food waste affect the true cost of cooking at home?+
It can — unused portions of purchased ingredients effectively raise the per-meal cost above what a simple receipt-divided-by-meals calculation would suggest.
Is fast food cheaper than sit-down restaurant dining?+
Generally yes on a per-meal basis, reflecting differences in labor cost, overhead, and service level between the two dining formats.
Does time spent cooking factor into the cost comparison?+
It's a separate consideration from the dollar-cost comparison — cooking at home generally takes more time than picking up prepared food, and how that time is valued varies by individual circumstances.
Does batch cooking lower the per-meal cost further?+
It can — spreading certain fixed costs, like active cooking time, across more servings from a single larger batch is a commonly described way to reduce the effective per-meal cost of home cooking.
Do delivery fees widen the cost gap with home cooking?+
Yes — third-party delivery platforms commonly add fees on top of the menu price, further increasing the cost of prepared food relative to cooking at home or picking food up directly.
