How it works
Turn quantity and unit price into a transparent total with waste, contingency and tax allowances.
Formula:
Adjusted quantity = Q × (1+waste); direct cost = adjusted quantity × unit price; total = (direct + contingency) × (1+tax).
Adjusted quantity = Q × (1+waste); direct cost = adjusted quantity × unit price; total = (direct + contingency) × (1+tax).
