Start with the decision
The question is not only how to calculate a number. It is what to charge, what a fee means, or whether a sale still works.
About FeeProofed
Pricing decisions should be checked before they cost you money.
FeeProofed helps sellers price products, understand platform fees, check profit, and decide whether ads can work. The goal is simple: show the math clearly enough that a non-technical user can make a better money decision.
Why it exists
Most pricing mistakes come from missing one line item.
A product can look profitable until processing fees, shipping labels, labor, packaging, discounts, or ad spend are added. FeeProofed is built for that moment. Instead of giving one isolated answer, it shows the parts of the decision that usually get skipped.
Show the math
Important pages show the formula, assumptions, worked example, and the inputs that change the result.
Keep defaults editable
Marketplace fees, labor rates, shipping costs, and ad targets are starting points. Your own numbers should be easy to test.
Connect the next step
A pricing answer should lead to profit, fee, discount, or ad math when that is the next decision a seller needs.
Who it helps
Built for people making real selling decisions
Marketplace sellers
Etsy, Shopify, Stripe, PayPal, Square, and other fee decisions where payout and profit are easy to mix up.
Handmade sellers
Products where materials, labor, packaging, waste, and platform fees all belong in the price.
Small ecommerce teams
Catalog and ad-spend decisions that need contribution margin, break-even ROAS, and discount checks.
Service businesses
Quotes and packages where time, delivery work, overhead, and target margin matter more than a simple hourly rate.
How the work is maintained
FeeProofed is built and maintained by the FeeProofed team. Fee-sensitive pages are checked against primary platform sources such as Etsy, Stripe, PayPal, Google Ads, and Amazon Ads, not copied from old summaries.
Default rates are editable starting points. The full source and review process is covered in the methodology.
Limits
FeeProofed calculators are estimates for planning and comparison. Platform rules, payment fees, taxes, refunds, discounts, fulfillment costs, and local requirements can change the final result.
The pages do not replace accounting, tax, legal, or financial advice. If you spot an outdated fee or unclear assumption, email mailtouseoo7@gmail.com.
