How the calculator works and what it’s for▾

How the food budget is calculated

The tool estimates costs from the size of your household and the eating level you choose. Adults and children are counted separately, because a child eats on average about 60 percent of an adult portion.

The daily estimate is scaled up to weekly, monthly and yearly figures, and the amount you spend on eating out is added in so the total reflects your real spending.

What you enter and what you get

Enter the number of adults and children, choose your eating level, and add a rough monthly figure for restaurants and takeaway.

You get food costs per day, week, month and year. The monthly figure is usually the most useful for budgeting, while the yearly total reveals just how large a share groceries take of your annual finances.

Who it is for

The calculator is handy for families, couples and people living alone who want to get a grip on their food budget or plan the cost of moving and daily life.

It also suits anyone aiming to save money and curious about how cutting back on eating level or dining out would change the monthly bill.

Good to know

The estimate is based on an average eating level, and real costs depend on where you shop, your diet and food waste. In the US the average grocery spend is roughly 300–450 dollars per month per adult on a moderate-cost plan, before eating out.

Treat the result as a starting point and refine it by tracking your own receipts for a few weeks.
