About the Tip Calculator
A no-fuss tip calculator. Type your bill total and the page immediately shows what 10%, 15%, 18%, 20%, and 25% tips look like — both the tip amount and the resulting grand total — so you can pick whichever rate feels right. Useful for restaurants, takeout, food delivery, taxis and rideshare, salons, hotel staff, and any other situation where a percentage tip is expected and you'd rather not do mental arithmetic in front of the server.
How to use it
- Type the bill total into the input field (decimals are fine — e.g. 42.75).
- Read off the tip amount and grand total for whichever percentage you want to leave.
- Round up or down to a sensible number — most people round the total to a whole dollar or to the nearest five.
- If you're splitting the bill, divide the grand total by the number of diners.

Frequently asked questions
- How much should I tip?
- In the United States, the customary range for restaurant servers is 15–20%, with 18% being a common middle. Exceptional service often gets 20–25%. For takeout the expectation is lower (0–10%). Bartenders, taxi drivers, hairdressers and food-delivery riders typically expect 15–20%. Outside North America norms vary widely — in many European, Asian, and Australian restaurants a small round-up or no tip at all is normal, and in some countries (notably Japan) tipping can be considered rude.
- Should I tip on the pre-tax or post-tax amount?
- Technically tipping on the pre-tax subtotal is more 'correct' because the tax is a government charge, not a service charge — and many fine-dining guides recommend it. In practice, most diners tip on the total they see at the bottom of the bill (post-tax) because it's the easier number. Either approach is widely accepted; the difference is usually only a dollar or two.
- What about service charges or auto-gratuity?
- Some restaurants automatically add a service charge for large parties (usually 6+ people), or in tourist areas. If a service charge is already on the bill, you don't normally need to tip on top — but it's still polite to leave a small extra amount (a few percent) if the service was excellent. Always read the bill before adding a tip.
- Does the calculator store my entries?
- No. The bill total never leaves your browser. The number is briefly reflected in the URL query so you can bookmark or share a specific calculation, but nothing is sent to a server.
