Tip Calculator

What the Tip Calculator Does

The Tip Calculator works out how much tip to leave, your total bill including the tip, and how much each person pays when you split the bill. It is useful at restaurants, cafes, bars, for food delivery, taxis, and personal services where tipping is customary.

It uses three simple formulas:

• Tip amount = Bill amount x Tip percentage
• Total to pay = Bill amount + Tip amount
• Each person’s share = Total to pay / Number of people

Results are an estimate only, not financial advice. Tip customs vary by country and service, so use the result as a guide and adjust for the service you received.

How to Use the Tip Calculator

1. Enter the bill amount before the tip, for example 80.00. If your bill already includes tax, decide whether you want to tip on the pre-tax or post-tax amount and enter that figure.
2. Choose a tip percentage, for example 15%, 18%, or 20%, or enter your own percentage.
3. Enter the number of people splitting the bill. Leave it at 1 if one person is paying.
4. Read the tip amount, total to pay, and per-person share. Adjust the percentage or number of people to compare options.

Worked Example

Bill: $80.00. Tip: 18%. People splitting: 4.

• Tip amount = $80.00 x 0.18 = $14.40
• Total to pay = $80.00 + $14.40 = $94.40
• Each person pays = $94.40 / 4 = $23.60

So you would leave a $14.40 tip, pay $94.40 in total, and each of the four people would pay $23.60.

Limitations

• The calculator does not know whether tax, a service charge, or a delivery fee is already included in the amount you entered. Check your receipt before tipping on top of a service charge.
• Results are rounded to the nearest cent. Splitting can leave a few cents of rounding difference, so one person may need to pay a cent or two more to match the total exactly.
• It does not convert currencies. Enter the bill in the currency shown on your receipt.
• It does not judge service quality. The percentage you choose is your decision.

Frequently Asked Questions

How much should I tip at a restaurant?

It depends on where you are and the service. In the United States, 15% to 20% of the pre-tax bill is common for sit-down restaurants. In many other countries, a smaller tip or rounding up is normal, and in some places tipping is not expected. When in doubt, check local custom.

Should I tip on the amount before or after tax?

Many people tip on the pre-tax subtotal. If you enter the post-tax total instead, the tip will be slightly higher. Either approach is acceptable; just be consistent and check whether a service charge is already added.

How do I split the bill fairly?

Enter the number of people splitting equally and use the per-person share. If people ordered very different amounts, calculate each person’s share separately instead of splitting the total equally.

What if a service charge is already on the bill?

If a service charge or gratuity is already included, you do not normally need to add a full tip on top. Check the receipt, and if you want to add extra for excellent service, tip a smaller additional amount.
