Grocery Cost Calculator
Knowing your grocery total before you get to the checkout helps you stick to a budget and avoid uncomfortable surprises. This calculator works like a running tally: add each item from your shopping list, enter how many you are buying and the price per unit, and the calculator multiplies them out and adds up the rows. You can enter a tax rate if your state charges sales tax on groceries (many US states exempt unprepared food, but some do not). The calculator starts with four rows covering common categories and you can add as many rows as you need with the Add Item button, or remove any row with the X button. All totals update instantly as you type. When you are done, copy the result to share with a household member or use as a reference while shopping. The unit options cover the most common grocery measurements: each (for individual items such as a can or a loaf), lb (pounds), kg (kilograms), oz (ounces), and L (litres). Enter items however they are labeled at your store.

How to use this calculator for meal planning
Enter your full week's grocery list to see how well it fits your food budget before shopping. Group items by category (produce, proteins, dairy, pantry staples) and add them row by row. When you find the total exceeds your target, you can immediately see which items contribute most to the cost and decide where to substitute a cheaper alternative.
Price estimates for your grocery list can come from your store's weekly circular, the store's website or app, or receipts from previous shops. Prices vary by store and region; update the calculator with your local prices for the most accurate estimate.

Grocery calculator: frequently asked questions
How do I use this grocery calculator?
Enter each item on your grocery list with its name, quantity, unit (each, lb, kg, oz, or L), and the price per unit. The calculator totals each row (quantity x price) and sums all rows to give a subtotal. If your state charges sales tax on groceries, enter the tax rate in the box above the table. The calculator shows subtotal, tax, and total. Click Add Item to add more rows, and the X button to remove any row.
What is the average weekly grocery bill in the US?
According to the US Bureau of Labor Statistics Consumer Expenditure Survey, average US household food-at-home spending is approximately $475 to $520 per month (roughly $110 to $130 per week). Costs vary significantly by household size, location, dietary preferences, and whether you shop at discount or premium retailers. The USDA publishes monthly food plan cost reports showing low-cost through liberal plan spending by household type at usda.gov.
How do I include sales tax?
Most US states do not charge sales tax on unprepared grocery food (produce, meat, dairy, bread, etc.), but some states do. States that fully exempt groceries include California, New York, and Texas; states that tax groceries include Alabama, Mississippi, and South Dakota. Enter your applicable grocery tax rate in the tax rate field. If groceries are tax-exempt in your state, leave the tax rate at 0%.
What does "per unit" mean for groceries?
Per unit means the price for one of whatever unit you select. If you choose "lb" and enter $3.99, the calculator prices each pound at $3.99. If you choose "each" and enter $1.49, each individual item costs $1.49. For items sold in L (litres) or kg (kilograms), enter the price per litre or per kilogram respectively. For items sold by the ounce (oz), enter the price per ounce.
How can I reduce my grocery bill?
The USDA's MyPlate and consumer guidance suggest: plan meals for the week before shopping to avoid impulse purchases; buy generic or store-brand products where the quality is comparable; use a shopping list and stick to it; shop sales and use store loyalty programmes; buy produce in season when prices are lower; and consider frozen vegetables, which are nutritionally equivalent to fresh and often cheaper. Buying staples such as rice, beans, and oats in bulk also reduces per-unit cost significantly.
