Why use this tool?

Use Grocery Basket Per-Unit Cost Calculator to compare your entered grocery-basket price assumptions with a stated formula and a reproducible example.

How the calculation works

Unit cost = total price ÷ quantity. Quantity must be positive and on one stated item, mass, volume, use or period basis. Fractional quantities are permitted. The rounded unit price may not reproduce the original total when multiplied back. Basket averages can hide different pack sizes, ingredients and product quality. Promotions and delivery are included only if you enter them. Choose one currency for every monetary input. The selector labels and formats amounts; it does not apply an exchange rate. Money displays use the selected currency’s standard minor units, including whole yen for JPY. Exact decimal arithmetic precedes rounding; halfway minor units round away from zero. Numeric input/result magnitudes are bounded by 9,007,199,254,740,991.

Example

Grocery Basket example: Currency = GBP; Total Price = 24; Quantity = 3. Result: £8.00.

Practical tip

Use a consistent quantity such as kilograms, litres or identical items. A mixed basket needs an explicitly chosen comparison unit.
