Free, instant calculators for online sellers. Work out PayPal, Stripe and Etsy fees, your true profit margin, and the ROAS you need to break even — no sign-up, no spreadsheets.
See the fee and your net on any PayPal payment — or reverse it: enter what you want to keep and we tell you what to charge.
Calculate →Stripe's 2.9% + 30¢ adds up fast. Check the fee on a charge, including international card and currency conversion surcharges.
Calculate →Listing, transaction, payment processing and Offsite Ads — the full Etsy fee stack on one sale, broken down line by line.
Calculate →Enter price and costs to get your profit, margin % and markup % — the numbers that decide whether a product is worth selling.
Calculate →Return on ad spend, plus your break-even ROAS from your margin — so you know the exact point where ads stop making money.
Calculate →Marketplace and payment fees typically take 8–15% of a sale before you have paid for the product, shipping or ads. A price that looks profitable at a glance can quietly lose money once the full fee stack is applied. These calculators use the published standard rates (checked November 2026) so you can price with the real numbers, not guesses.
Yes. Every tool on SellerCalc is free and works without an account.
We use each platform's published standard rates, listed on every calculator page with the date they were checked. Your account may have negotiated or legacy rates, and platforms change fees over time — treat results as close estimates and confirm against your own fee schedule.
Instead of asking "what do I keep from $100?", reverse mode answers "what must I charge to keep exactly $100 after fees?" It is the fastest way to price a product or invoice.
No. All calculations run in your browser; nothing you type is sent anywhere.
Standard commercial rates. Choose a direction: see what you keep from a payment, or what to charge to keep a target amount.
PayPal charges a percentage of the payment plus a fixed fee per transaction. The rate depends on how the payment is made and where your account is based. Fees are taken before the money reaches your balance, so the fee on a $100 payment at the standard US Checkout rate is $3.98 and you keep $96.02.
| Rate | Fee |
|---|---|
| US · PayPal Checkout / Venmo | 3.49% + $0.49 |
| US · Standard card payments | 2.99% + $0.49 |
| UK · Commercial transactions | 2.90% + £0.30 |
| International surcharge (US) | +1.50% |
Rates checked November 2026 against PayPal's published merchant fee schedule. Pay Later, micropayments and negotiated rates differ. Estimates only.
Stripe's standard online card pricing, with the surcharges that catch sellers out.
Stripe charges a percentage plus a fixed fee for every successful card payment. On a $100 US charge the fee is $3.20 and you keep $96.80. Because the fixed fee is the same on every payment, small charges lose a much bigger share: the same rate takes 5.9% of a $10 payment.
| Rate | Fee |
|---|---|
| US · Online card (domestic) | 2.90% + $0.30 |
| UK · Standard card | 1.50% + £0.20 |
| International cards | +1.50% |
| Currency conversion (US) | +1.00% |
Rates checked November 2026 against Stripe's published pricing. Stripe keeps the original fee on refunds; disputes cost extra. Estimates only.
The full Etsy fee stack for US sellers, line by line.
Every Etsy sale pays three core fees. The transaction fee (6.5%) and Etsy Payments processing (3% + $0.25) are charged on the total the buyer pays, including shipping — moving cost into shipping does not reduce them. The $0.20 listing fee applies per listing. If a sale came through Offsite Ads, add 12% or 15% depending on your shop's revenue tier.
| Fee | Rate (US) |
|---|---|
| Listing fee | $0.20 per listing |
| Transaction fee | 6.5% of price + shipping |
| Etsy Payments processing | 3% + $0.25 of the total |
| Offsite Ads (only on attributed sales) | 12% or 15% |
On a $25 item with free shipping, total fees are $2.83 and you keep $22.17. Rates checked November 2026 against Etsy's fees policy. Non-US sellers pay different processing rates and, in some countries, a regulatory operating fee. Estimates only.
Your real profit after product, shipping and fees.
Margin is profit as a share of the selling price — a $50 product with $20 profit has a 40% margin. Markup is profit as a share of your costs — the same product has a 66.7% markup. Sellers confuse the two constantly; pricing by markup when you meant margin quietly shrinks your profit. Tip: run your platform fees through the fee calculators above first, then enter the total here.
Return on ad spend — and the break-even point for your margin.
ROAS = revenue ÷ ad spend. A ROAS of 5 means $5 of revenue for every $1 of ads — but revenue is not profit. Your break-even ROAS is 1 ÷ margin: at a 40% margin you need a ROAS of at least 2.5 before ads make money, because only 40 cents of every revenue dollar is available to pay for them. Below break-even, more spend means more loss, however good the ROAS looks.
SellerCalc is a small set of free calculators built for online sellers — marketplace sellers, independent shops and digital product creators — who want to know what a sale is really worth after fees. Every calculator runs entirely in your browser, uses published standard fee rates, and shows its rates and sources on the page.
