Methodology
The site focuses on practical pricing, profit, payout, and quoting math that can be reused across sellers, freelancers, and small service businesses.
The goal is not to simulate every possible business rule. The goal is to keep the core decision visible, show the assumptions plainly, and make it easy to test the numbers with your own inputs.
Formulas
Pricing, margin, contribution, break-even, invoice, and payout tools are built from typed shared formulas instead of hidden spreadsheet logic. That keeps the calculators easier to reason about, easier to maintain, and easier to compare across related pages.
Assumptions
Some fee structures change by plan, country, category, promotion, or payment source. In those cases, the site uses a conservative baseline and keeps the controls editable so the page is still useful without pretending there is one perfect default for everyone.
Verification
Calculator builder
The builder exists so a useful calculator can become a starting point instead of a fixed endpoint. Templates explain the use case, and the builder lets you edit the fields, formulas, and outputs for your own workflow.
