Questions
Is this tax or financial advice?
No. Marginly does arithmetic on the numbers you type. It does not know your taxes, payroll or rent. Check big decisions with your accountant.
Does my data leave this page?
No. All math runs in your browser. Marginly sends nothing anywhere. It only remembers your theme and language choice.
Why doesn't it fill in fees for my platform?
Fees change and depend on your plan, country and payment method. Copy the rates from your own account or invoice. The example uses made-up rates.
How are refunds counted?
Marginly assumes that on a refunded order you give back the item price and keep paying the product, shipping and fees. So refunds cost refund rate × price × units. If you get products back to resell, your real loss is smaller.
What is break-even ROAS?
ROAS is sales from ads ÷ ad spend. At the break-even ROAS, ads eat all of your profit. Above it you make money. Below it you lose money on each order.
Why per order and not per unit?
Ads buy orders, and many costs are per order, like shipping. If buyers often take more than one, set average units per order. Price and product cost are per unit.
Is Marginly part of Shopify, Etsy, Amazon or TikTok Shop?
No. Marginly is an independent tool. It is not made by, linked to or approved by any of them.
