Sales pages are built to make a number look good, not to help you compare it against your actual costs. These calculators exist so you can run your own numbers before you sign with a payment processor, a bank, or a payroll provider — what card processing really costs once per-transaction fees are counted, the fully-loaded cost of an employee, what idle cash could earn in a high-yield business account, and more. All free, all instant, all in your browser.
