Is this calculator specific to Shopify?

The math is ecommerce-specific and works especially well for Shopify stores because it includes the costs Shopify merchants usually need to model: COGS, payment fees, shipping, returns, ad spend, inventory, conversion rate, or repeat purchases depending on the tool.

Should I use gross margin or contribution margin?

Use contribution margin when you are making advertising, discount, or growth decisions. Gross margin is useful, but contribution margin is stricter because it accounts for variable costs like payment fees, fulfillment, shipping, returns, and app costs.

Why does the tool use default values?

Defaults make the calculator useful immediately and show the shape of the result before you enter your own numbers. Replace them with your store's actual numbers before making a final decision.

How to use the result

The calculator compares current orders against projected orders from the new conversion rate, then multiplies incremental orders by AOV and margin.

Use incremental profit to decide how much design, copy, offer, or checkout work the lift can justify.
