Promotion simulator
Compare discount levels and save a proposal. Nothing changes in your store.
Simulations and saved proposals don’t change your store. Creating discounts in Shopify isn’t part of this version, so you create the discount yourself if you decide to run it.
Run a simulation
- Open Promotions and pick a product.
- Read the scenarios for no discount, 5%, 10% and 15%, up to your maximum discount.
- Add another whole-percent level if you want to compare one.
- Add an ad cost per order to see contribution after ad cost. This is your own estimate.
You can also try it in the demo.
The columns
| Column | Meaning |
|---|---|
| Price | Current price minus the discount. Compare-at prices are never the starting point. |
| Contribution per unit | Price minus unit cost and fees |
| Margin | Contribution as a share of the discounted price |
| After ad cost | Contribution minus your ad cost per order |
| Units to match | Units over 30 days that earn the same total contribution as current sales at full price |
| Your limits | Whether the scenario fits your promotion limits |
Units to match is arithmetic, not a forecast.
When you can’t save a proposal
A scenario can only be saved if it fits your limits and the product has:
- a known unit cost
- stock above your minimum
- product data less than 48 hours old
