Seller Profit Doctor

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. Call it when a seller asks whether Etsy Ads are worth it, what ROAS they need, or whether to turn ads off. Pass the item price, shipping charged, materials, label cost, and the daily budget or exact monthly spend; packaging is optional ($1 typical, flagged) and ROAS from the Etsy Ads page adds the monthly gain or loss and the fix. Returns the margin, break-even ROAS, ad sales and earnings, the monthly gain or loss and, when the ads lose money, the fix and what it's worth. US dollars; dated Etsy rules with sources. Free, no sign-in. Takes numbers only; nothing is stored.

Works out Amazon's fees on one unit at a price: the referral fee for the category (official, with the $0.30 minimum), 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. Call it when a seller asks what Amazon takes on a sale, what FBA costs for an item, or whether a price sits just over a fee line. Pass the price, category, fba or fbm, and for FBA the packed size and weight bands (or the packed dimensions); for FBM, the shipping the buyer pays. Returns each fee, the total outside and in peak, what's left, and the price lines where a fee steps; a line whose reading Amazon doesn't confirm is marked verified: false. The FBA figure is estimate: true: say "about", and point the seller to Fee Preview for their real fee. Dated rates with sources. Free, no sign-in. Takes numbers only; nothing is stored.

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. Call it when a seller asks where their money goes, whether their shop is healthy, or what to fix first. Set platform (etsy is the default) and pass that platform's Quiz v1 answers; each field says what it takes. Bands and "not-sure" are fine: every default used is listed (isDefault), so ask for the real number. There may be no grade yet: with too few answers, level is null, word is "Not enough answers yet", and grade.missing lists the answers to get a grade. Ask for them and call again; losses found still show. Amazon: fulfillment, storage and returns dollars are estimates from third-party rate cards (estimate: true, in estimatedLeakTotal, apart from leakTotal); a typed fbaFee from Fee Preview makes that fee the seller's own. Money is US dollars; shares are fractions (0.1 is 10%). Every result carries the dated rates with sources. Free, no sign-in. Takes numbers only; nothing is stored.

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. Call it when a seller asks what Etsy takes from a sale, or what they keep from it before costs. Pass the item price and shipping charged; optionally the sales tax rate, whether it was an Offsite Ads sale and at which rate, and a currency mismatch. Returns each fee, the total, its share of the order and what's left, in US dollars, with the dated Etsy rules and their sources. Free, no sign-in. Takes numbers only; nothing is stored.

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. Call it when a seller asks what Offsite Ads cost them, whether to price them in, or whether to opt out. Pass the item price, shipping charged, the shop's Offsite Ads rate (12-percent past $10,000, 15-percent under, or off), orders a month, and the share of sales from Offsite Ads if the seller knows it (else Etsy's typical 10%, flagged). Materials and label cost are optional and add how far orders could fall before the price rise leaves the seller worse off. Returns the fee per attributed order and on average, the monthly and yearly cost, the price fix and its value if orders hold, and when opting out is possible. US dollars; dated Etsy rules with sources. Free, no sign-in. Takes numbers only; nothing is stored.

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. Call it when a seller asks what to charge, how to price for a profit, or what their break-even price is on Etsy. Pass materials, label cost, shipping charged and the shop's Offsite Ads rate (12-percent, 15-percent or off); packaging, the Offsite share, ad spend with orders, and targetProfitPerOrder or targetMargin are optional. Returns the price, the order at that price line by line, the break-even price and what each extra dollar keeps. US dollars; dated Etsy rules with sources. Free, no sign-in. Takes numbers only; nothing is stored.

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. Etsy: listing, transaction, processing, Offsite Ads, Etsy Ads minimums, shipping lines, Etsy Plus, tax facts. Shopify: plan prices on both billings, card rates, the third-party processor fee, currency, chargebacks, Shopify Tax. Amazon: plans, referral by category and the media closing fee (official), and FBA, storage, returns, peak and coupon fees (third-party estimates: Amazon's own tables sit behind the Seller Central login). Call it to cite a platform's fees, to answer what a fee is, or to check how current the numbers are. Takes no figures; platform defaults to etsy. Free, no sign-in. Nothing is stored.

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. Call it when a seller charges less for shipping than the label costs, offers free shipping, or asks how to price shipping on Etsy. Pass the item price, shipping charged, label cost and orders a month; packaging (else $1 typical, flagged), the share of orders shipping free, the Offsite Ads rate and share, and materials are optional and sharpen the fix. Returns the gap, the fix price, every fix's monthly value and how far orders could fall before it leaves the seller worse off. US dollars; dated Etsy rules with sources. Free, no sign-in. Takes numbers only; nothing is stored.

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. Call it when a seller asks whether to upgrade or downgrade their Shopify plan, whether yearly billing is worth it, or why a bigger plan costs them more. Pass monthly card sales (US dollars), the current plan, billing and processor; with both processors, the share Shopify Payments handles. Returns every plan's cost, the cheapest plan on the current billing and on either billing, the break-even sales, and the yearly-billing difference, with the dated Shopify rates and sources. A move's value holds at these sales; below the break-even the bigger plan costs more. Free, no sign-in. Takes numbers only; nothing is stored.
