Disclosure and disclaimer
How this site makes money
MarkupMath earns affiliate commissions. Some links to software and services pay us a commission if you sign up. It costs you nothing extra, and it is how the calculators stay free with no account and no email wall.
Where a page contains links that can earn a commission, that is stated on the page itself, above the links — not only here.
What that does and doesn't buy
- No vendor pays for a ranking or a recommendation. Commission rates differ between products, and we will not order a comparison by what pays best.
- Prices and features are checked, with dates shown. Vendors change pricing without notice; a figure here is accurate as of the date printed beside it and no later.
- We are not customers of every product listed. Where a comparison is drawn from public pricing pages and documentation rather than hands-on use, the page says so.
Disclaimer
The calculators on this site produce estimates for business planning. They are not tax, accounting, legal or financial advice, and no professional relationship is created by using them.
Pricing decisions depend on facts this site cannot see — your actual overhead, your local market, your contracts, your insurance and your obligations. Check the output against your own books, and talk to your accountant before making a decision that matters. You are responsible for what you charge.
Your figures stay yours
Every calculation runs in your browser. The numbers you type are never transmitted to this site or to anyone else, and nothing is stored. See the privacy page for the full picture.
