How much money does your family throw away?
Direct answer: this calculator covers household sizes, not only a family of four. It estimates uneaten groceries from your weekly spend and a waste-rate scenario, and it shows the EPA per-person benchmark ($728 a year) beside that estimate. It does not promise a lower bill. The statistics page explains the sources. The meal planning guide is the dinner sequence. For the broader picture, read our food waste statistics.
Your best guess is fine. This sets the grocery budget the waste estimate is based on.

How this food waste calculator works
The calculator estimates how much of your weekly grocery spend may go uneaten, then projects it across a month and a year. It is a planning estimate, not an exact accounting of your kitchen.
We start from the EPA's 2025 estimate that the average consumer loses about $728 per year — roughly $14 per week — to food that is bought but never eaten. We use that as the reference baseline for your household size.
Your personalized estimate multiplies your weekly grocery spend by a waste-rate assumption you choose (5% if you rarely waste food, up to 20% if food regularly expires), then scales the weekly figure by 4.33 for a month and 52 for a year.
These waste rates are scenario assumptions, not measured household data. The goal is to make an invisible cost feel concrete so you can decide whether to change how you plan and shop.
Food waste cost by household size
EPA per-person baseline scaled to common household sizes. These are reference estimates, not personal figures.
| Household size | EPA baseline (weekly) | EPA baseline (annual) |
|---|---|---|
| 1 person | $14 | $728 |
| 2 people | $28 | $1456 |
| 3 people | $42 | $2184 |
| 4 people | $56 | $2912 |
| 5 people | $70 | $3640 |
| 6+ people | $84 | $4368 |
Annual figures are the EPA per-person estimate ($728) multiplied by household size. See our food waste statistics for the full source list.
Turn the number into a plan
A calculator cannot know whether your spinach, chicken, or herbs will get used twice. That is the meal-plan layer. Build a week where ingredients repeat on purpose, leftovers become a second dinner, and one tired night has a planned fallback.

How much money does the average person waste on food?
The EPA estimates the average American consumer loses roughly $728 per year — about $14 per week — to food that is purchased but never eaten. That figure comes from the EPA's 2025 report on the cost of food waste to consumers.
How much food does a family of four waste?
Scaled from the EPA per-person estimate, a household of four may waste roughly $2913 of food per year, or about $56 per week. This is a SummitPlate estimate derived from the EPA per-person figure, not a separately published household number.
What causes the most food waste at home?
The biggest home drivers are produce that spoils before it is used, leftovers that never become another meal, ingredients bought for a single recipe, duplicate purchases because no one checked the pantry, and unplanned takeout nights that leave planned groceries unused.
Can meal planning reduce food waste?
Yes. Meal planning reduces waste by giving every ingredient a destination before you shop, reusing ingredients across multiple dinners, and planning a fallback meal so a tired night does not turn into takeout. The impact depends on your current habits, so we frame any savings as an estimate rather than a guarantee.
How do I stop throwing away groceries?
Start by planning the week's dinners before you shop, building the grocery list from that plan, and choosing recipes that share ingredients. Check the fridge and pantry first so you do not rebuy what you already have, and store perishables properly so they last long enough to be cooked.
What foods are wasted most often?
Highly perishable items lead the list: leafy greens, fresh herbs, berries, bread, and dairy. Cooked proteins and leftovers are also commonly tossed. The more perishable an item is, the more important it is to have a specific meal planned for it before you buy.
