Tip Calculator

What the tip calculator does

This tip calculator works out the gratuity on a bill and tells you the total to pay, instantly. Enter the bill amount, choose a tip percentage (15%, 18%, 20%, or any number you like), and it shows the tip and the grand total. Add the number of people splitting and it divides everything evenly, including the tip, so each person knows exactly what they owe. It is a clean, browser-based online tip calculator with no signup, built for the quick moment at the end of a meal when you just want the math done.

This page focuses on the tip itself calculated on the pre-tax bill, which is how most people and most etiquette guides recommend tipping. If your receipt already includes sales tax and you would rather tip on the after-tax amount, use the Tip Calculator with Tax, which is built specifically for that. Keeping the two separate means you always get the answer you actually want.

How to use the tip calculator

Three inputs and you are done. The result updates as you type:

1. Enter the bill amount. Use the pre-tax subtotal if you want to tip the standard way, or the total shown if you prefer to tip on the full figure.
2. Choose a tip percentage. Tap a common preset like 15%, 18%, or 20%, or type a custom rate.
3. Set the number of people (optional). Leave it at 1 for a solo bill, or enter the group size to split.
4. Read the result. The calculator shows the tip amount, the total with tip, and the per-person share when you split.

Because it is a fast online tool, it is easy to try a couple of percentages side by side, for example comparing what 18% and 20% add to the same bill before you decide.

The tip formula and a worked example

The core method is one multiplication and one addition:

• Tip = bill × (tip percent ÷ 100)
• Total = bill + tip
• Per person = total ÷ number of people

Say the bill is 60 and you want to leave 20%. The tip is 60 × 0.20 = 12, the total is 60 + 12 = 72, and split between three people that is 72 ÷ 3 = 24 each. The table below shows the tip and total for common bill sizes at the percentages most people use, so you can eyeball a fair amount even without entering anything.

How much to tip: a quick guide

Tipping norms vary by service, and this restaurant tip calculator works for all of them. As a general guide in the United States:

• Sit-down restaurants: 15% to 20% of the pre-tax bill, with 20% considered standard for good service.
• Counter service and takeout: optional, often 10% or a small flat amount.
• Bartenders: around 1 to 2 per drink, or 15% to 20% of the tab.
• Food delivery: 15% to 20%, with a minimum of a few units for small orders.
• Taxis and rideshare: 10% to 20%.
• Hairdressers and personal services: typically 15% to 20%.

The table below shows per-person amounts for a split bill at 18%, which is a common middle-ground tip for groups.

Tipping by country: a quick orientation

The "normal" tip depends heavily on where you are eating, and getting it wrong in either direction is easy when you travel. The United States leans on tipping the most; many European countries fold service into the price and tipping is a modest round-up; and a few places consider tipping unusual or even unwelcome. The table below is a rough orientation for sit-down restaurants, and this calculator lets you plug in whatever local norm applies.

When in doubt, check whether a service charge already appears on the bill before deciding what to add. The calculator handles any percentage, including zero, so you are never locked into a default.

Common mistakes to avoid

A handful of slip-ups lead to tipping too much, too little, or an awkward split:

• Tipping on the after-tax total by accident. Standard practice is to tip on the pre-tax subtotal. If your receipt shows tax and you want to handle it deliberately, use the Tip Calculator with Tax.
• Forgetting an auto-gratuity. Large groups often have a service charge already added. Check the bill before adding more, or you will tip twice.
• Rounding the split unevenly. When a per-person figure has odd cents, round up slightly so the total is covered, not under.
• Splitting before adding the tip. Add the tip to the bill first, then divide, so the gratuity is shared fairly.
• Confusing percent and amount. Entering 20 as a flat amount instead of 20% gives a very different result on a small bill.

Tip percentages at a glance

Most people settle on a tip percentage out of habit, but it helps to see what each rate actually costs across a range of bills. The table below lays out the common rates so you can pick a level of generosity and read off the amount, or work backwards from a round total you have in mind. It also doubles as a fast sanity check on a result the calculator gives you.

The 10% column is the easiest to compute in your head and forms the basis for the others: 20% is double it, 15% is 10% plus half again, and 25% is 10% doubled plus another half. Once that anchor is set, every other rate is a quick adjustment.

Tips and related calculators

To split fairly when one person ordered far more, calculate each person's items separately and apply the same tip percentage to each, rather than dividing the whole bill evenly. For quick mental math, 10% is just moving the decimal one place left, and 20% is double that, so a fast 20% estimate is "first digit doubled." And when in doubt about service quality, round to a comfortable total.

This tool is part of the Online Calculators hub. For receipts where you want to tip on the taxed amount, the Tip Calculator with Tax is the right companion. The Percentage Calculator handles any percentage question beyond tipping, the Average Calculator helps when everyone chips in different amounts, and the Age Calculator is there whenever you need it.

Frequently asked questions

How does the tip calculator work? Enter the bill, pick a tip percentage, and optionally the number of people. It multiplies the bill by the percentage to find the tip, adds that to the bill for the total, and divides by the group size for each person's share.

Should I tip on the bill before or after tax? Standard etiquette is to tip on the pre-tax subtotal. This calculator uses whatever bill figure you enter, so enter the subtotal for the conventional approach. To tip on the taxed total deliberately, use the Tip Calculator with Tax.

What is a normal tip at a restaurant? In the United States, 15% to 20% of the pre-tax bill is normal for sit-down service, with 20% widely treated as the standard for good service.

How do I split a bill with the tip included? Enter the number of people. The calculator adds the tip to the bill first, then divides the total evenly, so each person's share already includes their part of the gratuity.

Can I use a custom tip percentage? Yes. Beyond the 15%, 18%, and 20% presets, you can type any percentage you want, which is useful for exceptional service or for places with different norms.

What if the bill already has an auto-gratuity? Many restaurants add a service charge for large groups. Check the receipt first; if a gratuity is already included, you usually do not need to add more on top.

Is this online tip calculator free? Yes. It runs entirely in your browser with no signup, and nothing you enter is stored or sent anywhere.

How do I quickly estimate a 20% tip in my head? Take 10% of the bill by moving the decimal one place left, then double it. On a 45 bill, 10% is 4.50 and 20% is 9.00.
