Know the economics
before the offer goes live.
Eight practical calculators for the questions behind a promotion. All inputs stay in this browser. All worked examples are hypothetical.
Did the promotion add contribution
Compare a promotion's contribution with a no-promotion baseline. Include discounted prices, unit costs, campaign spending and supplier funding.
How much more must a discount sell
Calculate the additional unit sales a discount needs to preserve contribution, including fixed campaign spending.
The free item still has a cost.
Check contribution per buy-X-get-Y-free bundle, its effective discount and the bundle volume needed to match full-price unit sales.
Margin and markup use different denominators.
Convert between margin and markup, and calculate the selling price required for a target margin or markup.
What if demand responds differently to price
Explore price, quantity, revenue and contribution under an explicit constant-elasticity demand assumption.
How much funding makes the promotion work
Calculate the supplier support a promotion needs to match baseline contribution, with per-unit and fixed funding separated.
What happens outside the promoted SKU
Adjust a promotion's contribution change for displaced product sales, later-period payback and halo contribution.
Mark down now or hold for later
Compare marking down inventory now with holding it for a later price, accounting for expected sales, salvage and holding costs.
Put every campaign in context.
Import a CSV into the workbench to compare product–campaign rows, pressure-test the baseline, and produce a decision report.
