How does this calculator work?
Enter a shopping list (one item per line: name price qty), an optional sales tax %, and a budget. Total = Σ(price × qty) × (1 + tax%). The calculator shows each line's subtotal, total tax, and whether you are over or under budget — adjust quantities until you fit your spend.
Formula
How this is calculated
Type or paste your shopping list, one item per line. Each line should contain the item name (optional), unit price, and quantity — for example "Milk 3.49 2" means two litres of milk at 3.49 each. If you omit the quantity the calculator assumes 1 unit. Lines starting with # are treated as comments and ignored. The calculator multiplies each item's unit price by its quantity to get the line subtotal, then sums all line subtotals to get the basket total before tax.
If you enter a sales tax rate, the tax amount is added on top of the subtotal. In the United States, state sales tax on groceries ranges from 0% (most states exempt food) up to around 7% for states that apply the full rate; check your local rules. In countries where prices include VAT, enter 0 in the tax field. If you set a budget, the calculator shows how much you are over or under it so you can decide which items to put back.
All figures are rounded to two decimal places for display, matching standard currency precision. Results update instantly as you type — you can paste a list from a note-taking app or build it up line by line.
Frequently asked questions
One item per line in the format "name price qty". The name is optional; if you omit it just write "price qty" (e.g. "3.49 2") or just a price (e.g. "3.49") for a single unit. The calculator reads the last two numeric tokens on each line as price and quantity.
Use the tax field when you want to add a percentage on top of listed prices — typical if you are shopping in the US and prices are shown before tax. If prices already include VAT or tax (as in most European countries), leave the tax field at 0.
It is the subtotal divided by the number of active line items, giving a rough indication of the average spend per product type. It is not the average price per unit — if you bought 2 litres of milk at 3.49 the line subtotal is 6.98, which is what goes into the average.
