Terms of Use

No PayPal affiliation

SellerMaths is independent and is not affiliated with, sponsored by, or endorsed by PayPal. PayPal product names are used only to describe the calculators and source material.

Allowed use

You may use the calculators to plan prices, compare PayPal fee scenarios, check invoice math, and understand how different inputs change the estimate.

No misuse

Do not present SellerMaths as PayPal, use results as fake official quotes, attack the site, or use automated scraping in a way that harms availability.

Content limits

The formulas and explanations are provided for estimates and learning. They do not guarantee a PayPal charge, approval decision, payout, exchange rate, tax result, or business outcome.

Content and intellectual property

The page text, calculator layout, examples, and site structure belong to SellerMaths unless otherwise stated. You may link to pages and use the results for your own planning, but you may not copy the site as a competing calculator without permission.

Liability limits

Use the site as a planning aid. For pricing, tax, legal, accounting, or credit decisions that matter, check PayPal, your records, and a qualified professional.

Availability and changes

The site can change, pause, or remove calculators, pages, examples, source links, or stored assumptions at any time. SellerMaths does not guarantee uninterrupted access or that every PayPal product is covered in every country.
