Runs the free profit check-up for an Etsy shop, a Shopify store or an Amazon seller. Returns the grade (a word such as Watch, with level 1 Healthy to 5 Losing money), what one order (Amazon: one unit) and the month keep after fees, ads and costs, the loss total, and the top 3 losses, each with its fix and what it's worth a month at the seller's numbers if orders hold. It fits a seller who asks whe

Works out Etsy's fees on one sale, line by line: the $0.20 listing fee, the 6.5% transaction fee, the 3% + $0.25 payment processing fee (also charged on sales tax), the 2.5% currency conversion when it applies, and the Offsite Ads fee (12% or 15%, at most $100) when the sale came from an Offsite Ad. It fits a seller who asks what Etsy takes from a sale, or what they keep from it before costs. Take

Works out what Etsy's Offsite Ads cost a shop at its share of sales (12% or 15% of an attributed order, at most $100 an order), per order and per month, and the item price that covers the fee. It fits a seller who asks what Offsite Ads cost them, whether to price them in, or whether to opt out.

Works out the shipping gap for an Etsy shop: what the label and packaging cost beyond what the buyer pays, per order and per month, and the fixes: the item price that covers the gap with shipping kept under Etsy's $6 search line, calculated shipping, and (for free-shipping shops) building shipping into items of $35 and up, each worth so much a month if orders hold. It fits a seller who charges les

Works out the ROAS at which an Etsy shop's Etsy Ads pay for themselves (break-even ROAS = order ÷ what an ad order keeps after Etsy's fees and costs), the most an ad can cost per sale, and, with the shop's ROAS, what the ads gain or lose a month. It fits a seller who asks whether Etsy Ads are worth it, what ROAS they need, or whether to turn ads off. Takes the item price, shipping charged, materi

Works out the item price at which one Etsy order keeps a target profit after Etsy's fees (listing, 6.5% transaction, 3% + $0.25 processing), the average Offsite Ads fee, Etsy Ads spread over orders, materials, packaging and the label. The target is dollars per order or a share of the order; with neither, it returns the break-even price. It fits a seller who asks what to charge, how to price for a

Works out how many more orders a sale or coupon needs just to keep the same profit a month, for one item on Etsy, Shopify or Amazon. Each platform's fees are worked out at the full price and again at the sale price: percentage fees fall with the price and fixed fees stay (Etsy's listing and processing fees, Shopify's 30¢), so the answer is extra orders = kept at full price ÷ kept on sale − 1.

Works out the fees on one sale on Etsy (listing, transaction, processing; Offsite Ads optional), on a Shopify store (card fee by plan through Shopify Payments) and on Amazon (referral fee by category, the Individual plan's per-item fee, an optional FBA fee the seller types), side by side, each column equal to that platform's single fee tool; with orders a month, Shopify's plan and Amazon's Profess

Works out the ROAS (ad revenue ÷ ad spend, as Meta or Google reports it) at which Facebook, Instagram or Google ads pay for themselves, when the ad sends buyers to a Shopify store, an Etsy listing or an Amazon listing, with that platform's own fees on the order. Break-even ROAS = order ÷ what one ad order keeps after the platform's fees, product, label, packaging and refunds; that amount is also

Works out which Shopify plan (Basic, Grow, Advanced) costs least at a store's card sales: each plan's price plus the card fees that change with the plan (or Shopify's third-party fee on sales through another processor), the card sales above which each move up pays for itself, on monthly and yearly billing, and what yearly billing takes off the price. It fits a seller who asks whether to upgrade or

Works out every fee on one order of a US Shopify store, line by line: the Shopify Payments card fee by plan (premium cards optional), the international card and currency conversion fees, the 1.25% for mixing Shopify Payments with another card processor, another processor's own fee and Shopify's third-party fee on top (2%, 1% or 0.6% by plan), and the PayPal exemption from that fee when Shopify Pay

Works out Amazon's fees on one unit at a price: the referral fee for the category (official, with the $0.30 minimum where the category has one), the $1.80 media closing fee (official), and for FBA an estimate of the fulfillment fee from third-party 2026 rate cards by size tier and weight, with the 3.5% fuel and logistics surcharge, and the peak-season fee from October 15 to January 14. It fits a s

Works out the ACoS (ad spend ÷ the sales the ads bring) at which Amazon Sponsored Products pay for themselves: what a unit an ad brings keeps before the ad (after the referral fee, the FBA fee estimate or the label and packaging, storage and the landed cost) as a share of what the buyer pays. Gives it outside peak season and in peak (October 15 to January 14), when the FBA peak fee lowers it. It

Returns one platform's fee table, the one this server's numbers use: every fee and rule with its value, a plain label, its source link and the day it was checked, whether it's official or a third-party estimate, and both values where sources disagree, plus when the table is due for its next check.
