How to use this calculator

Calculation method — version 1

Planned quantity = required quantity × (1 + allowance / 100). Packages = planned quantity / package contents, rounded upward. Cost = whole packages × tax-inclusive package price + delivery. Both prices allow at most 2 decimal places; money calculations use integer cents or grosze.

Data and scope

Use the supplier's current tax-inclusive price and the same quantity unit in both fields. Apply allowance once. Labour, taxes, discounts and currency exchange are not added.
