Things to Keep in Mind

These calculators do not fetch live carrier rates, marketplace fees, duty schedules, ad platform data, exchange rates, tax rates, or fulfillment provider pricing. Enter the current assumptions that apply to your store.

Tips & Best Practices

  • Use recent invoices, carrier bills, payment processor reports, and marketplace statements when available.
  • Separate variable costs from fixed overhead so unit margin is easier to compare across products.
  • Stress-test margin with higher shipping, lower conversion, higher waste, and deeper discount assumptions.

Glossary of Terms

Bundle price
The customer-facing selling price for the combined products.
Discount cost
The dollar value of a promotion or markdown included in the bundle margin model.

Frequently Asked Questions

Are these ecommerce margin results guaranteed?
No. Results are planning estimates based only on your entered assumptions. Actual profit can change because of refunds, taxes, chargebacks, carrier adjustments, promotions, inventory shrink, and marketplace rules.
Is my pricing or order data stored?
No. The calculator runs locally in your browser and does not store, transmit, or review the prices, costs, rates, or order assumptions you enter.
Can this model a free gift bundle?
Yes. Include the free gift cost in item costs or discount cost so the bundle profit reflects the promotion.
