About This Tip Calculator
A tip calculator helps you quickly figure out how much to leave for service
and how much each person owes when splitting the bill. Enter your bill
amount, choose a tip percentage using the quick preset buttons (10%, 15%,
18%, 20%) or type a custom value, and optionally divide the total by the
number of people. The results update instantly — no need to click a button.
Use the round-up switch to bump the total bill to a whole dollar amount,
which makes paying in cash and splitting simple.
Tipping norms vary widely. In the U.S., 15–20% is common for sit-down
restaurants, while counter service and takeout may call for less. In many
other countries, tipping is not expected or a small round-up is enough.
This calculator runs 100% client-side in your browser. Your bill amount,
tip percentage, and party size are never uploaded, transmitted, or stored
on any server, so your financial data stays private.
How much should I tip at a restaurant?
In the United States, 15–20% is standard for sit-down restaurants. 15% is considered the baseline for adequate service, 18–20% for good service, and 20%+ for excellent service. Counter service and takeout often require less or no tip.
Is it rude to tip 10%?
In the U.S., 10% is generally considered low for sit-down service, though it may be appropriate for counter service or poor service. In many other countries, 10% is generous or tipping is not expected at all.
Should I tip on the pre-tax or post-tax amount?
Etiquette experts often suggest tipping on the pre-tax subtotal, but many people tip on the post-tax total. Either is acceptable — the difference is usually small.
How does bill splitting work?
Enter the number of people in the bill split field. The calculator divides the total (bill plus tip) evenly by that number to show each person's share.
What does the round-up button do?
Round up adjusts the tip so the total bill becomes a whole dollar amount. This makes paying in cash and splitting simpler.
