Many founders focus on ROAS when evaluating their campaigns, but revenue alone does not equal profit. Without understanding contribution margin and real costs, brands often scale ads that quietly destroy their margins.
Margin Engine is a simple collection of profitability tools designed for Shopify and ecommerce brands running paid advertising.
Margin Engine helps ecommerce brands calculate their true break-even ROAS and make better advertising decisions before scaling ad spend.
Why This Site Exists
Most advertising dashboards show ROAS, but they rarely show the real profitability behind those numbers.
In ecommerce, several factors affect profit:
- Product cost
- Shipping cost
- Payment processing fees
- Refund rates
- Discounts and promotions
Margin Engine was created to simplify these calculations and give founders a clearer view of their real margins.
