Privacy
The calculator runs entirely in your browser. The amount and rate you last used are kept in your browser's local storage on your own device so they are still there next time. There is no account, no server-side database and nothing is transmitted to us.
Analytics
This site uses Google Analytics to count visits and see which pages are useful. It records the page you viewed, a rough location derived from your IP address (which is truncated before storage), and general device and browser details. It does not receive the values you type in — those stay in your browser. Google explains its part at policies.google.com/technologies/partner-sites.
Advertising
This site is funded by Google AdSense. Google and its partners may use cookies or device identifiers to serve and measure ads, including personalised ads where you have consented. Manage your choices at myadcenter.google.com and read how Google uses data from sites using its services at policies.google.com/technologies/partner-sites.
Affiliate links
Some outbound links to accounting software are affiliate links. If you sign up through one we may earn a commission at no extra cost to you.
