• sellerprofit_ads_breakeven

  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, 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.

• sellerprofit_ads_roas_breakeven

  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 the most an ad can cost per order. It fits a seller who asks what ROAS they need, why ads with a ROAS of 3 still lose money, or whether to pause Meta or Google ads. Takes the item price, product cost and label; optionally the platform (shopify default), shipping charged, packaging ($1 typical, flagged), the refund share, and the platform's own field (Shopify plan, Amazon category and fulfillment fee). The monthly ad spend with the reported ROAS or ad revenue adds the monthly gain or loss and the fix; all orders a month check the ad platform's count against the seller's own orders. Returns the order line by line, what an ad order keeps, the margin, the break-even ROAS, and with spend the monthly gain or loss. Says that Meta and Google count purchases with their own attribution windows, so their ROAS can differ from the store's own orders. US dollars; dated rates with sources. Free, no sign-in. Takes numbers only; nothing is stored.

  shallow
• sellerprofit_amazon_ads_breakeven

  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 fits a seller who asks what ACoS they need, whether their Amazon ads pay, or what to bid. Takes the price, category, fba or fbm, the packed size and weight bands or the packed dimensions (FBA) or shipping charged (FBM), and the landed cost. Optional: the monthly ad spend with the ACoS (or the ad sales) for the monthly gain or loss and the fix, and the conversion rate for the highest cost per click that pays. Amazon publishes no ACoS benchmark: the seller's own break-even is the test. The FBA fee and storage are estimates (estimate: true); Amazon's Fee Preview shows a seller's real fee. Assumes the Professional plan. Dated rates with sources. Free, no sign-in. Takes numbers only; nothing is stored.

  shallow
• sellerprofit_amazon_fees

  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 seller who asks what Amazon takes on a sale, what FBA costs for an item, whether a price sits just over a fee line, or whether FBA or shipping it themselves costs less. Takes 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. Or takes both (with packed, labelCost and, optionally, packaging, minutesPerOrder with hourlyValue, unitsPerMonth, inboundSplit and freightToAmazon) and compares Amazon shipping it with the seller shipping it for the same item, outside peak and from October 15 to December 31: each side's costs and what's left per unit, storage from the packed size, monthly totals, and the label + packaging + time where the answer flips. Assumes the Professional selling plan (the Individual plan adds $0.99 an item). 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; Amazon's Fee Preview shows a seller's real fee. Dated rates with sources. Free, no sign-in. Takes numbers only; nothing is stored.

  shallow
• sellerprofit_box_billing

  Works out the billable weight of one box with USPS (Priority Mail, Ground Advantage), UPS (Daily Rates and Retail Rates) and FedEx, from its outside size in inches and its actual weight, with each carrier's 2026 dimensional weight rules: sides rounded up to whole inches, cubic inches ÷ the divisor (139 for USPS since July 12, 2026, only for boxes over 1 cubic foot; UPS 139 Daily, 166 Retail; FedEx 139), rounded up to a pound, and the larger of that and the actual weight. It fits a seller who asks why a label cost more than the weight suggests, whether a box is too big, what dimensional weight a box has, or whether a smaller box would bill less. Takes lengthIn, widthIn, heightIn and weightLb or weightOz; optionally otherBox (a second box size) to compare. UPS and FedEx bill a large box (over 96 in long or over 130 in length plus girth) at least 90 lb; USPS prices by weight up to 108 in length plus girth (Ground Advantage commercial takes up to 130 in at a flat oversized price), and its row shows no billable weight past that; a box over 165 in length plus girth is refused. Returns per carrier the size weight, the billable weight, whether it bills on actual or size weight, and the largest box that still bills on the actual weight; USPS Ground Advantage cubic fit as information; warnings; and notes. No label prices (they depend on zone and account); divisors can differ by account. Dated carrier rules with sources. Free, no sign-in. Takes numbers only; nothing is stored.

  shallow
• sellerprofit_checkup

  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 where their money goes, whether their shop is healthy, or what to fix first. Takes platform (etsy is the default) and that platform's Quiz v1 answers; each field says what it takes. Bands and "not-sure" are accepted: every default used is listed (isDefault). 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 a grade needs; 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.

  shallow
• sellerprofit_compare_fees

  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 Professional plan are spread over each order. It fits a seller who asks which platform takes less of a sale, Etsy vs Shopify vs Amazon fees, or which is cheaper to sell on. Takes the item price and shipping charged; optionally orders a month, the Offsite Ads rate, the Shopify plan, the Amazon category, plan and FBA fee. Returns each platform's fee lines, fixed cost per order, total, what's left and its share of the sale, and which costs least at these numbers, with the caveat that fees are one part of the choice. US dollars; dated rates with sources. Free, no sign-in. Takes numbers only; nothing is stored.

  shallow
• sellerprofit_etsy_fees

  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. Takes 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.

  shallow
• sellerprofit_offsite_ads

  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. Takes 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.

  shallow
• sellerprofit_price_for_margin

  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 profit, or what their break-even price is on Etsy. Takes 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.

  shallow
• sellerprofit_rates

  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). It serves 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.

  shallow
• sellerprofit_sale_breakeven

  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. On Amazon the sale is a coupon plus the 2.5% coupon fee (third-party estimate); Amazon's public pages don't state whether the referral fee is on the price before or after the coupon, so both readings are returned. It fits a seller who asks whether 25% off is worth it, how many more sales a discount needs, or whether to join a sales event. Takes the platform, the item price, the discount percent, materials and label; optionally shipping charged, packaging ($1 typical, flagged), orders a month, and the platform's own field: Etsy Offsite Ads, Shopify plan, Amazon category and fulfillment fee. Returns one order at full price and on sale (price, each fee, costs, kept), the fee change, the extra orders needed and, with orders a month, the orders needed and what the sale costs if orders don't rise. When the sale price keeps nothing, it says no number of orders makes the sale pay. US dollars; dated rates with sources. Free, no sign-in. Takes numbers only; nothing is stored.

  shallow
• sellerprofit_shipping_gap

  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 less for shipping than the label costs, offers free shipping, or asks how to price shipping on Etsy. Takes 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.

  shallow
• sellerprofit_shopify_order_fees

  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 Payments is the main processor. It fits a seller who asks how much Shopify takes per sale, what one order costs in fees, or what's left of an order. Takes the item price, shipping charged, the plan (basic, grow, advanced) and how the order was paid; orders a month, billing and the app bill put the plan price and apps on each order. Returns each fee with its working, the total, its share of the order and what's left, and with orders the plan and apps per order. US dollars; dated Shopify rates with sources. Free, no sign-in. Takes numbers only; nothing is stored.

  shallow
• sellerprofit_shopify_plan_fit

  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 downgrade their Shopify plan, whether yearly billing is worth it, or why a bigger plan costs them more. Takes 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.
