Seller-fee calculator alternative
A transparent marketplace fee calculator alternative for sellers
Use BoringToolsKit when you want editable fee assumptions, profit math, and a reproducible marketplace comparison dataset that can be cited or downloaded.
Quick comparison
| Need | BoringToolsKit fits when | Consider another workflow when |
|---|---|---|
| Etsy, eBay, Amazon, and Shopify fees | Dedicated calculators plus one cross-platform marketplace seller-fee comparison. | Use platform dashboards for account-specific promotions or category exceptions. |
| Citation and data | CSV dataset and how-to-cite blocks are built for references. | Use paid seller software if you need inventory sync. |
| Privacy | No product catalogue upload required. | Use marketplace-native tools for live order reconciliation. |
Choose the workflow that fits the job
This comparison is intentionally narrow. BoringToolsKit fits when the visible inputs, local calculation, and stated capability boundary match your task; a larger or account-connected service can fit better when you need its specific connected workflow.
Where this workflow fits
This workflow fits when you are pricing a listing before you post it: platform fees per channel, shipping and payment costs, and the profit left at your asking price. The cross-platform comparison dataset is downloadable and citable, which is what paid fee-scanner tools rarely offer.
Honest limits
BoringToolsKit does not read your live seller account, promotions, or category-specific exceptions. Fee schedules change; the datasets state their verification date, and account-specific pricing always belongs to the marketplace dashboard.
Common questions
Which marketplaces are covered?
Etsy, eBay, Amazon, and Shopify each have a dedicated fee calculator, plus a single comparison that prices the same example listing across all four.
Are the fee rates current?
Each dataset states when it was verified against the marketplace's published schedule. Marketplaces change fees several times a year — always confirm against the platform before pricing a live listing.
Can I model my own shipping cost?
Yes. Shipping and payment processing are editable inputs, so you can enter the actual label cost you pay rather than a platform default.
Does it include listing renewal or subscription fees?
The calculators cover per-sale fees. Shop-level subscriptions and listing renewals are fixed costs you should add separately when computing monthly profitability.
