PlainCalc provides general-purpose calculators and educational explanations. Nothing on this site is financial, investment, tax, legal, accounting, or employment advice.

Marketplace fee tools

Etsy, Amazon, and other platform fee schedules change and depend on category, country, order details, ads, and promotions. Our constants are dated approximations for planning. Official seller policies and dashboards control what you are charged. PlainCalc is not affiliated with Etsy, Amazon, or any marketplace.

Pay & overtime tools

Overtime and salary conversions are illustrative arithmetic. Eligibility for overtime, regular-rate calculations, exemptions, and state rules vary. Do not rely on these tools to resolve wage disputes; consult your employer, a state labor agency, or a qualified attorney.

Energy tools

Electricity and EV cost estimates depend on your utility rate, device duty cycle, and charger pricing. They are not guarantees of bill amounts.

No warranties

The site is provided “as is” without warranties of accuracy, completeness, or fitness for a particular purpose. To the fullest extent permitted by law, operators are not liable for decisions made using these estimates.

Ads

Advertising — when enabled — does not constitute an endorsement of advertised products or services.
