Free seller profit calculator

See what you actually keep.

Revenue is not profit. MarginFern subtracts Etsy or Shopify fees, payment processing, shipping, ads, and returns — then shows your true profit per order and the price you need to charge to break even.

Why sellers get surprised

The dashboard shows revenue. Your bank account shows the truth.

A $35 sale does not put $35 in your pocket. Between marketplace fees, payment processing, ad spend, and the occasional return, a “profitable” product can quietly lose money.

01

Fees are not the whole story

Etsy charges its 6.5% transaction fee on shipping too. Payment processing adds a percentage plus a fixed fee. Offsite Ads can take another 15%.

02

Break-even, not guesswork

See the exact price where an order stops losing money — after returns and ad costs, not just the product cost.

03

Returns are a real cost

A 5% return rate is not a rounding error. The calculator spreads expected refunds and handling costs across every order.

04

Every fee is editable

Use the presets as a starting point, then enter the rates from your own seller dashboard. Rates vary by country, plan, and category.

05

No signup, no store access

Nothing is uploaded. The math runs in your browser. No account, no trial, no “connect your store” prompt.

06

Share it or print it

Copy a link that restores every input, or print a clean one-page PDF report for your records or a business partner.

The calculator

What do you actually keep on this order?

Pick a preset, then adjust any number. Results update as you type. All amounts are in the market selected in the top-right of the calculator.

MarginFern is an independent tool and is not affiliated with Etsy, Shopify, Printful, or Printify. Defaults are estimates for the US market and may not match your account. Fees and tax rules change; confirm current rates with Etsy’s fee help and Shopify’s pricing page. Nothing here is financial advice.

How it works

Three inputs, one honest number.

1 Pick a preset

Start with your platform

Etsy, Shopify, or print on demand. The presets load typical fees, then let you change anything that does not match your account.

2 Add your real costs

Include the awkward parts

Product cost, shipping you pay, packaging, average ad spend, and your return rate. These are the numbers dashboards usually miss.

3 Read the result

Profit, margin, break-even

See profit per order, margin, break-even price, and a monthly projection after fixed costs. Share the scenario or print it.

Common questions

What sellers ask before trusting the number.

How much does Etsy take from a sale?

Etsy charges a 6.5% transaction fee on the item price, shipping, and gift wrap. Etsy Payments adds a processing fee that varies by country — commonly 3% + $0.25 in the US. There is also a $0.20 listing fee, and Offsite Ads take 15% (12% for sellers above $10k in yearly sales) on orders attributed to those ads.

That is before your product cost, the shipping you pay, packaging, and returns. The calculator includes all of them.

What is a good profit margin for an Etsy shop?

Aim for 20–30% net margin after every cost. Under 10% is fragile: one return or a small increase in ad spend can turn a “profitable” order into a loss. The badge in the results panel uses these bands.

Does this include ads and returns?

Yes. Enter your average ad spend per order and your return or refund rate. The calculator subtracts expected refunds and return-handling costs from profit, and includes them in the break-even price. Offsite Ads can be entered as a percentage fee.

Do I need an account or a store connection?

No. The calculator runs entirely in your browser. Nothing is uploaded or stored. The share link contains your numbers in the URL so you can bookmark a scenario or send it to someone.

Are the fee defaults accurate for my country?

The defaults use common US rates. Etsy payment processing, currency conversion, and regulatory fees vary by country, and Shopify plan prices vary by region and billing cycle. Choose your market and edit any fee to match your seller dashboard.

How is the break-even price calculated?

The calculator adds fixed fees (listing, payment fixed fee), product costs, shipping, packaging, ads, and return handling, then divides by one minus your percentage fees and return rate. It then subtracts the shipping you charge the buyer. Sell below that price and the order loses money.
