How it's calculated

Fixings = locations × fixings per location × (1 + waste ÷ 100), rounded up. Packs are rounded up separately.

Calculations use consistent units for your selected measurements. The waste allowance is applied once to the measured requirement. Whole purchase quantities are rounded up.
