• Working out a tip and splitting a restaurant bill.
• Checking a suggested gratuity on a card machine.
• Dividing a total fairly across a group.

Tip Calculator: limits and things worth knowing

• Tipping norms vary enormously and are cultural rather than arithmetic: 15-20% is standard in the US, 10-15% is generous in the UK, and tipping is uncommon or even unwelcome in Japan.
• Check whether service is already included before adding a tip — many restaurants add 12.5% automatically and a card machine may still prompt for more on top.
• Card terminals sometimes calculate the suggested tip on the tax-inclusive total rather than the pre-tax subtotal, which quietly raises the effective rate.
• Splitting evenly is simplest; splitting by item is fairer when the orders differ significantly.

Is it private and secure?

Your privacy is built in. Tip Calculator runs completely on your device, so whatever you enter stays in your browser and is never transmitted, logged or stored on any server.

Network activity: none. Nothing is sent and nothing is fetched. This tool makes no network request at all once the page has loaded — which is why it keeps working if your connection drops.

You do not have to take that on trust — our privacy proof page publishes the Content-Security-Policy that enforces it, lists every third party it permits, and shows how to verify the whole claim yourself.
