Why use this tool?
Use Sale Item Per-Unit Cost Calculator to compare your entered sale-item 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. The entered regular price is a comparison assumption. The tool does not verify a discount claim, price history or availability. 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
Sale Item example: Currency = GBP; Total Price = 100; Quantity = 5. Result: £20.00.
Practical tip
Compare the final price with a meaningful regular price, with the same taxes and fees included.
