Why SellerGauge

We show you how the number was calculated, not just the answer.

Get answers fast

Every tool is built to answer a real pricing or payout question in seconds — no sign-up, no fluff.

See what is behind the number

We show you the formula, the example math, and the exact rate assumptions so nothing feels like a black box.

Check the sources yourself

Platform fees and tax references link to official docs so you can verify the math, not just trust it.

Worked Examples

Real scenarios beat empty input fields.

Every calculator comes with worked examples, assumptions, and practical caveats so you can see how the math plays out before you plug in your own numbers.

01

A $100 sale through PayPal

How much does PayPal take? What do you keep? And what should you charge if you want to net exactly $100?

02

Pricing an Etsy product with margin in mind

After shipping, transaction fees, and offsite ads, is there still enough room to make the listing worthwhile?

03

Finding break-even before you lower a price

How many orders do you actually need to cover fixed costs once variable costs and per-order fees are in the mix?

04

Comparing channel fees on the same order

Run one realistic order through multiple marketplaces and compare the actual payout instead of trusting headline fee tables.

05

What a cross-border payout really leaves you

Receive fees, withdrawal fees, and FX costs can stack up fast. See what actually reaches your bank before you rely on the number.

06

Does a payout delay create a cash gap?

Reserve holds and settlement timing can leave you short if you are counting on that money for inventory, ads, or contractors.

07

The FX rate you see vs. the rate you keep

Markup and fixed conversion costs quietly shrink the converted amount. See the gap before you lock in a quote.
