Example 1
- Bill 100
- Tip 10%, 1 person, on the full bill
tip 10.00; total 110.00; each 110.00
100 × 10% gives 10 of tip, total 110 for one person.
Tip calculator
Type the bill, a percent, and an optional split. The calculator multiplies the base by the percent and adds it to the bill. 100 and 10% give a tip of 10, total 110. You can count from the full bill or from the amount before tax.
Tip from a bill, a percent, and a split. The base can be the full bill or the bill minus tax. VAT: net and gross. Percent alone: percentage of a number.
Result
Bill amount ({{currency}}), Tip %, Number of people (blank = 1) and Tax on the bill ({{currency}}, optional). Tip shows up here.
How it works
A tip is the base times the percent over 100. On a full-bill base, 100 and 10% give 10, a total of 110, and 110 for one person. A bill of 200 and 15% for two people give a tip of 30, a total of 230, and 115 each. Eighty and 20% for four people give 16, 96 together, 24 each. Zero percent leaves the bill alone: 50 and 0% is 50. One hundred twenty and 10% for three people give 12, 132 together, 44 each.
When you pick the amount before tax, the base is the bill minus tax. Bill 110, tax 10, 10% give a base of 100 and a tip of 10. The amount to pay is still bill plus tip, so 120, not base plus tip. When tax is greater than or equal to the bill, that mode refuses, because the base cannot be zero or negative. On a full-bill base, typed tax is not subtracted: it only matters in before-tax mode.
Blank people means 1. Typed 1.0 passes as one person. 1.5 people is refused, because we do not split a half person here. Blank tax is 0. Percent is non-negative: 12.5% of 240 for two people gives a tip of 30, a total of 270, 135 each. 18% of 75.50 gives 13.59 of tip and 89.09 together. We divide the total with the tip, not the bill alone.
The header symbol puts zloty, dollars, euros, or pounds on the same number. There is no exchange rate: 100 stays 100 after you switch USD to PLN. The metric/US switch does not move the amounts. Authority rates, a receipt feed, and tipping habits from another country are not in the form. You type the percent. The page does not guess whether 10% is polite.
The bill and the percent need values. An empty percent does not insert 10 from the example. Type 100 and 10, leave people blank, click Calculate, and match 10, 110, and 110. Then switch to before tax, add tax 10 on a bill of 110, and see a tip of 10 with a total of 120.
VAT net-gross next door applies a rate to a net amount, not a tip for the server. Percentage of a number is the product alone, with no split. Here you keep the bill, optional tax, a percent, and a split.
How to use
- Type the bill amount and the tip percent. Both values are needed before a result.
- Leave people blank if you pay alone. Empty people means one person.
- Tax is optional. Fill it when the tip should use the amount before tax.
- Pick the base: amount before tax, or the full bill including tax.
- Click Calculate. 100 and 10% give 10 of tip, total 110. At 110, tax 10, and a before-tax base the total is 120.
Formula
base = bill − tax when the mode is before tax, otherwise base = bill
tip = base × percent / 100
total = bill + tip; each = total / people. Bill > 0. Percent ≥ 0. People ≥ 1, whole (1.0 is allowed). Blank people = 1. Blank tax = 0. On a before-tax base: tax < bill.
Bill, percent, and tip
Tip = base × percent / 100. 100 and 10% give 10, total 110. Before-tax base: 110 minus 10, base 100.
- Bill
- The receipt amount. 100 at 10% is tip 10 and total 110. 80 and 20% for four people is 16, 96, and 24.
- Tip
- The percent of the base. 10 from 100 and 10%. 0% on 50 leaves tip 0 and total 50.
- people
- A split of the total with the tip. Blank people means 1. Zero is refused. 1.5 does not pass.
Examples
Example 2
- Bill 200
- 15%, 2 people, on the full bill
tip 30.00; total 230.00; each 115.00
200 × 15% gives 30, total 230, about 115 each.
Example 3
- Bill 80
- 20%, 4 people
tip 16.00; total 96.00; each 24.00
80 × 20% gives 16, 96 across four people gives 24 each.
Example 4
- Bill 50
- 0%, 1 person
tip 0.00; total 50.00; each 50.00
50 × 0% gives 0 of tip, the bill stays 50.
Example 5

Frequently asked questions
What do 100 and 10% give for one person?
Tip 10, total 110, 110 each. 200 and 15% for two people give 30, 230, and 115.
When do you subtract tax from the bill before the tip?
When you pick the before-tax base. Then 110 minus 10 gives a base of 100. On a full-bill base, typed tax is not subtracted from 110.
How do I calculate tax and tip together?
Enter the bill, the tax and the tip percent. On a bill of 110, tax 10 and 10% in before-tax mode the base is 100, the tip is 10, and you pay 120 (bill plus tip). The calculator does not reverse a tip from an amount already paid.
What if tax is equal to or larger than the bill?
In before-tax mode the calculator refuses, because the base cannot be zero or negative. On a full-bill base tax never enters the base.
Does a blank people field count as zero guests?
No. Blank people means 1. Zero people is refused. Typed 1.0 passes. 1.5 does not.
Does switching USD to PLN in the header convert a bill of 100?
No. 100 stays 100. The symbol changes. Type amounts already in the chosen currency. The formula has no exchange rate.
Does this compute VAT, sales tax, or tax on the tip?
No. The tax field is an amount from the bill that you may subtract from the base. There are no authority rates. You type the tip percent.
Is zero percent no extra, or a refusal?
A valid result. 50 at 0% gives a tip of 0 and a total of 50. An empty percent does not insert zero. You must type zero.
How does a four-way split work at 80 and 20%?
Tip 16, total 96, 24 each. We divide the total with the tip, not the bill alone.
What do 75.50 and 18%, and 240 and 12.5% for two people, give?
13.59 of tip and 89.09 together. The second example: 30, 270 together, 135 each.
Does the page guess a polite percent?
No. You type the percent. 10, 12.5, 15, or 20 is your call. There is no custom card for the restaurant.
Knowledge sources
The tip is the percent of the bill you type. This is not a tax rule.
