Editorial Policy
RotoCurve exists to publish useful calculator pages and plain-language decision guides. Pages should help users understand a real calculation, not just fill search results.
Content standards
- Every calculator page should explain the use case, key inputs, result limitations, and related tools.
- Pages should avoid misleading promises, fake earnings claims, copied content, and unsupported guarantees.
- Marketplace, carrier, payment, and tax assumptions should be presented as editable estimates, not official policy.
- Pages should be updated when a fee, rule, or calculator assumption needs correction.
Corrections
If a calculation, rate, page title, or explanation looks wrong, email help@rotocurve.com with the page URL and source. Corrections are prioritized when they affect user decisions.
Advertising independence
If advertising is added later, calculator pages and guides should remain useful without requiring users to click ads or enter sensitive information.
Quality and usage notes
This page is intended to help users make clearer planning decisions with transparent assumptions. Results are estimates and should be checked against official sources when money, taxes, shipping, or marketplace rules are involved.
How to use this page well
Use this page as a planning aid, not a final quote or official rule. Replace defaults with your own numbers, compare more than one scenario, and check any important fee, tax, carrier, or marketplace policy against the official source before acting.
- Use real costs instead of rounded guesses whenever possible.
- Review the result together with shipping, returns, discounts, taxes, and payment fees.
- Save or repeat the calculation when costs change, because small inputs can change profit quickly.
