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
Tip from a bill, a percent, and a split. Header currency only formats the amounts, with no exchange rate. Not a tax authority, not sales tax on the service, and not a tipping-custom card.

How it works
This tip calculator multiplies a base by a percent and adds the result to the bill. On the full bill, 100 and 10% give a tip of 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. A bill of 80 and 20% for four people give 16 of tip, 96 together, 24 each. Zero percent leaves the bill alone: 50 and 0% is 50.
If you tip on the pre-tax amount, the base is bill minus tax. Bill 110, tax 10, 10% gives a base of 100 and a tip of 10, and the amount to pay is still bill plus tip, so 120. When tax is greater than or equal to the bill, that mode is an error, because the base cannot be zero or negative. On a full-bill base, a tax in the field is not subtracted: it only matters when you pick before-tax.
Blank people means 1. Typed 1.0 passes as one person. 1.5 people is an error, because we do not split a half person in this formula. 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.
Header currency 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 and US switch does not change the tip. This is not a tax authority, not a receipt feed, and not a custom card for the United States or Japan. You type the percent. The page does not guess whether 10% is polite.
How to use
- Type the bill amount and the tip percent. Both values are required before a result.
- Leave people blank if you pay alone; an empty people field 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.
- Read the tip, the amount to pay, and the per-person figure in the header currency.
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.
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
- Bill 120
- 10%, 3 people
tip 12.00; total 132.00; each 44.00
120 × 10% gives 12, 132 across three people gives 44 each.
Example 6
- Bill 110, tax 10
- 10%, base before tax
tip 10.00; total 120.00; each 120.00
Base 110−10=100, 10% gives 10, total 120 to pay.
Example 7
- Bill 75.50
- 18%, 1 person, on the full bill
tip 13.59; total 89.09; each 89.09
75.50 × 18% gives 13.59 of tip, total about 89.09.
Example 8
- Bill 240
- 12.5%, 2 people
tip 30.00; total 270.00; each 135.00
240 × 12.5% gives 30, 270 across two people gives 135 each.
Frequently asked questions
Does a blank people field count as zero guests?
No. Blank people means 1. Zero people is an error. Typed 1.0 passes. 1.5 does not, because we do not split a fraction of a person in this formula.
When do you subtract tax from the bill before the tip?
Only 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.
What if tax is equal to or larger than the bill?
In before-tax mode that is an error, because the base cannot be zero or negative. On a full-bill base tax never enters the base, so that error does not apply there.
Does switching USD to PLN in the header convert a bill of 100?
No. 100 stays 100. The symbol changes. To work in another currency economically, type the amounts in that 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 and no receipt feeds. You type the tip percent yourself.
Is zero percent an error, or a bill with no extra?
It is a valid result. 50 at 0% gives a tip of 0 and a total of 50. An empty percent computes nothing. You must type zero if you want no extra.
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. An uneven split where one person takes the wine is not in this form.
Does the metric and US switch change 10 of tip?
No. Tip is an amount. Length and mass units do not multiply the bill. The same number stays in the header currency.
Does a comma in 75.50 work the same as a dot?
Yes. 75.50 times 18% gives 13.59. Skip spaces inside thousands. Type 2400, not 2 400, if you ever enter a larger bill.
Does the page guess a polite percent for the restaurant?
No. You type the percent. 10, 12.5, 15, or 20 is your call. There is no custom card for the United States, Japan, or Poland in this form.
