TOOL DIRECTORY FAQ

Choose the right tool for the decision.

Which calculator should I use?

Use Landed Cost for imported unit cost, Shopify & Stripe Profit Margin for order economics, ROAS & Max CPA for ad thresholds, and Gateway Fees for processing costs. Use Free Shipping Threshold for a shipping subsidy and Discount & Margin Impact for promotion volume. For product SEO, use the Schema Generator for JSON-LD and the Title & Meta Description Checker for search-result copy.

Can I use my own rates and costs?

Yes. Enter your own product, freight, fulfillment, ad and payment-fee assumptions. The gateway calculator also offers Stripe and PayPal Checkout presets plus custom percentage and fixed-fee inputs. Treat presets as starting points and verify rates with your provider.

Does the break-even ROAS calculator include fixed payment fees?

It uses a percentage gateway fee and does not model a fixed per-transaction charge. Use the Shopify & Stripe Fee / Profit Margin Calculator when you need to include percentage and fixed order fees together.

Can the Product Schema Generator publish markup to my Shopify store?

No. It creates a script you can copy. Check whether your theme already outputs Product markup, publish through the correct theme or app workflow, then test the live product page with Google.
