Model a discount’s effect on order contribution and create UTM links to track your campaigns.

Discount and contribution per order

Enter consistent pre-tax amounts in one currency. The result subtracts only entered costs; it is not accounting profit. Initial values illustrate the calculation.

Formula: price × (1 − discount/100) − product cost − fulfilment/delivery − variable fees − acquisition.
