Tip Calculator & Bill Splitter
Our free tip calculator makes it effortless to figure out the right gratuity for any restaurant bill. Enter your total, pick a tip percentage (10%, 15%, 18%, 20%, or 25%), set how many people are splitting the tab, and get instant results — no math required. All calculations run entirely in your browser; nothing is sent to any server.
Use the Equal Split tab for straightforward group meals where everyone pays the same share. Switch to Unequal Split when diners want to divide the bill by custom percentages — just assign a share to each person and the tool calculates exactly what each one owes, including their portion of the tip.
The optional Round up toggle rounds each person’s amount up to the nearest dollar, which is handy when paying in cash and you want to avoid counting coins.

Frequently Asked Questions
How do I use this tip calculator? Enter the bill total, choose a preset tip percentage or type a custom one, then set the number of people. The tip amount, total, and per-person share appear instantly.
What is the standard restaurant tip? In the United States, 15–20% is the widely accepted standard for sit-down restaurant service. 18% is increasingly common as a baseline. For takeout, 10% or a flat amount is typical.
How does the split bill calculator handle unequal shares? In the Unequal Split tab, add each person and assign them a percentage of the bill (e.g. 60% / 40%). Shares must add up to 100%. The tool then applies the chosen tip rate and divides the grand total by those percentages.
Should I tip on the pre-tax or post-tax amount? This gratuity calculator uses the pre-tax bill you enter. Tipping on the pre-tax total is common practice, though tipping on the after-tax amount is also widely accepted.
Can I use a custom tip percentage? Yes — type any value in the Custom input next to the preset buttons. The preset highlights clear automatically so the custom value takes over.
