It depends on local norms. Many people tip on the pre-tax subtotal, but some tip on the total. This calculator supports both.

Q: What if I’m splitting but one person pays more?

Use the per-person result as a baseline and then adjust manually for uneven splits.

Calculate tip, total, and per-person split in seconds — with service-quality presets, a tip slider, rounding options, and a mini tip vs. bill visual.

Background

A tip is usually a percentage of your bill. This calculator lets you include optional tax, decide whether to tip on tax, split the total, and round in a way that feels practical (like “round the total to a whole dollar”).

Enter your bill

Currency

This controls how results are displayed (symbol + formatting).

Bill amount

Enter the pre-tax or post-tax bill — your choice (tax is optional below).

Service quality

Choosing a preset updates the tip percent + slider.

Tip method

Tip by percent

Tip by amount

Percent is best for quick norms (15–20%). Amount is best when you want an exact tip.

Tip amount

Enter the exact tip you want to leave. The calculator will still apply tax / split / rounding options.

Tip percent (when using percent)

0% 18% 30%

Common tips: 15%, 18%, 20%.

Split between (people)

Use 1 if you’re not splitting.

Tax percent (optional)

Leave blank if your bill already includes tax or you don’t want to include it.

Tip calculation

Tip on (bill + tax)

If unchecked, tip is calculated on the bill amount only (before tax).

How this calculator works

Tax: tax = bill × (tax%/100)
Tip base: bill only or bill + tax
Tip: tip = tipBase × (tip%/100)
Total: total = bill + tax + tip
Split: perPerson = total / people

Formula & Equation Used

Tax: tax = bill × (tax%/100)

Tip base: tipBase = bill or bill + tax

Tip: tip = tipBase × (tip%/100)

Total: total = bill + tax + tip

Per-person: perPerson = total / people

Tip (amount mode): tip = tipAmount

Effective tip % (amount mode): effective% = (tip / tipBase) × 100

Example Problem & Step-by-Step Solution

Example 1 — Basic tip (no tax)

Bill: 48.75, Tip percent: 18%.
Tip: tip = 48.75 × (18/100) = 48.75 × 0.18 = 8.775.
Total: total = bill + tip = 48.75 + 8.775 = 57.525.
Rounded to cents: Tip ≈ 8.78, Total ≈ 57.53.

Example 2 — Split the total

Bill: 82.40, Tip percent: 20%, People: 2.
Tip: tip = 82.40 × 0.20 = 16.48.
Total: total = 82.40 + 16.48 = 98.88.
Per-person: perPerson = 98.88 / 2 = 49.44.

Example 3 — Add tax (and don’t tip on tax)

Bill: 56.00, Tax: 8%, Tip percent: 18%.
Tax: tax = 56.00 × 0.08 = 4.48.
Tip base (tip-on-tax unchecked): tipBase = bill = 56.00.
Tip: tip = 56.00 × 0.18 = 10.08.
Total: total = bill + tax + tip = 56.00 + 4.48 + 10.08 = 70.56.

Example 4 — Tip by amount (flat tip)

Bill: 50.00, Tip amount: 10.00.
Tip: tip = 10.00 (amount mode).
Total: total = 50.00 + 10.00 = 60.00.
Effective tip % (optional): effective% = (10.00 / 50.00) × 100 = 20%.

Frequently Asked Questions

Q: Should I tip on tax?

Depends on local norms. Many people tip on the pre-tax subtotal. This calculator supports both.

Q: Why does rounding change the tip?
