What is a tip calculator?
A tip calculator works out the gratuity you want to leave on a bill. Enter the amount on your receipt and a percentage. You’ll see the tip, the total payment, and each person’s share. If your receipt already includes a service charge, check it before adding another tip.
How to use the tip calculator
- Start with the receipt. Choose its currency and enter the total before any additional tip. Include any tax already on the bill.
- Choose your tip. Tap a percentage or enter a custom rate. To tip on the pre-tax subtotal, open “Tax & rounding options,” enter the tax printed on your receipt, and select the before-tax option.
- Set the party size. Use one person if you’re covering the table. For an equal split, enter the number paying and read the per-person amount in the bill summary.
How it works and which formula it uses
The tip base is the bill amount. If you choose before-tax tipping, the calculator first subtracts the included tax from that base. Tax stays in the final payment.
Total payment = bill amount + tip
Average share = total payment ÷ number of people
The tip is rounded to the currency’s smallest listed unit. If the total cannot be divided evenly, the summary shows how many people pay one extra unit. Choosing “Round total up” adds the difference to the tip.
A practical example
Three friends receive a $78.00 bill, including $6.00 in tax. They choose a 20% tip. Here’s how the before-tax option changes their payment.
| Calculation | Tip on full bill | Tip before tax |
|---|---|---|
| Tip base | $78.00 | $72.00 |
| Tip at 20% | $15.60 | $14.40 |
| Total payment | $93.60 | $92.40 |
| Each of 3 pays | $31.20 | $30.80 |
Why use ProTipCalculator.com?
Compare three tip rates on the same receipt, see exactly who covers a rounding difference, and keep your currency selection when you open another calculator. If dinner was unevenly shared, the shared items bill splitter can divide an appetizer among only the diners who ordered it.
Choosing your inputs
A receipt can list a suggested tip beside a total that already includes tax. Decide which amount you want to tip on before choosing a percentage. If you enter the printed total and also enter the tax, tick the before-tax option to subtract that tax from the tip base.
How to interpret the result
If a party splits a small total many ways, the displayed average may leave a remainder. Collect the extra smallest units from the number of diners shown in the summary. Multiplying just the lower share by the party size can leave the bill short.
Frequently asked questions
Should I enter the subtotal or the final bill?
Enter the amount due before your new tip, including tax. To calculate a tip on the subtotal, enter the included tax separately and turn on before-tax tipping.
How do I handle gratuity already on the receipt?
Check the included amount first. The automatic gratuity calculator subtracts it from your target tip so you can see how much extra to leave.
What if an equal split leaves a cent over?
For a $100 total divided three ways, two people pay $33.33 and one pays $33.34. The same rule uses whole yen for JPY and thousandths of a dinar for KWD.
Does changing the currency convert the amount?
The selector sets the currency of the numbers you enter and the precision of each result. For a receipt in Pakistani rupees, select PKR and enter the rupee amount printed on it.
