How these calculators work

Every calculation runs in your browser. Nothing you type is sent anywhere. Payment fee defaults are copied from PayPal's and Stripe's public US pages, with the check date shown on each page, and you can edit every number. Hours calculators show results as hours and minutes and as decimal hours.
