Tip Calculator & Bill Splitter
To calculate a tip, multiply the bill by the tip percent as a decimal. An 18% tip on a $50 bill is 0.18 × 50 = $9, for a total of $59. Split three ways, that is $19.67 each.

Turn the tip percent into a decimal
18 ÷ 100 = 0.18
“Percent” means “per hundred”, so divide by 100.
= 0.18
Read the steps as text
- Turn the tip percent into a decimal. 18 ÷ 100 = 0.18 “Percent” means “per hundred”, so divide by 100.
- Work out the tip. 0.18 × $64.50 = $11.61 The tip is the percent applied to the whole bill.
- Add the tip to the bill. $64.50 + $11.61 = $76.11
- Split evenly between 2 people. $76.11 ÷ 2 = $38.06 Each person pays the same share, including their part of the tip.
How the tip and total are calculated
A tip is a percentage of the bill, so the maths is the same as any percentage problem: turn the percent into a decimal by dividing by 100, then multiply by the bill. Add that tip to the bill to get the total you pay. For $50 at 18%, that is 18 ÷ 100 = 0.18, then 0.18 × $50 = $9 tip, for a $59 total.
To split the total evenly, divide it by the number of people. Everyone pays the same amount, and that amount already includes their share of the tip, so nobody needs to work out their own tip separately.
Rounding the tip
Turning on “round the total up to a whole dollar” raises the total (and therefore the tip) to the next whole dollar, which is handy when paying in cash or splitting a card bill into round numbers. It never rounds down, so the tip only ever increases, by less than a dollar in total.
How much should you tip?
In the United States and Canada, sit-down restaurant tipping of 15–20% of the pre-tax bill is standard, with 20% common for good table service. Food delivery and rideshare tips are usually 10–20% or a flat few dollars, and many people round up for a haircut, taxi or bar tab rather than doing exact percentages.
Tipping norms vary a lot by country. In much of Europe, Australia and New Zealand a service charge is often already included and tipping is optional or a small rounding-up; in Japan and South Korea tipping is unusual and can even seem confusing to staff. When travelling, it is worth checking local etiquette before assuming US-style tipping applies.
Splitting a bill fairly
An even split is simplest and works well when everyone ordered roughly the same amount. If people had very different meals, a fairer approach is to add up each person's own items first, then split only the shared tax and tip evenly across the group — you can still use this calculator for that last part by entering just the shared extras as the bill.
Frequently asked questions
- What is a normal tip percentage?
- In the US, 15–20% of the pre-tax bill is typical at a sit-down restaurant, with 20% common for good service. Delivery and rideshare tips are often 10–20% or a flat amount.
- Do you tip on the amount before or after tax?
- Most etiquette guides say tip on the pre-tax subtotal, but many people simply tip on the total shown on the receipt for simplicity. Either is common; consistency matters more than which one you pick.
- How do I split a bill fairly when people ordered different amounts?
- Add up each person's own food and drink first, then split only the shared tax and tip evenly. This calculator handles the equal-split maths; itemising who owes what for their own order is done separately.
- Is it rude not to tip?
- In the US it is generally considered inappropriate not to tip for table service, since service staff often rely on tips as a large part of their income. In many other countries tipping is optional or already included as a service charge.
- Why does rounding up change the tip percentage slightly?
- Rounding the total up to a whole dollar adds a few extra cents to the tip so the total lands on a round number. The percentage shown is your starting choice; the actual tip paid is a little higher once rounded.
