Monster Free Tip Calculator
Enter the bill, pick a tip percentage, and split the total evenly between everyone at the table — in seconds.
| Tip amount (20%) | $0.00 |
| Total bill with tip | $0.00 |
| Split between | 1 person |
How it works
Tip = bill × tip %. Total = bill + tip. Per-person = total ÷ number of people. Everything updates live as you type — no calculate button needed.
Formula & worked example
Formula: Tip = bill × tip %. Total = bill + tip. Per-person share = total ÷ number of people.
Worked example: An $86 bill with a 20% tip: tip $17.20, total $103.20, and split 4 ways that is $25.80 per person.
When to use this
- The bill lands and the table needs tip, total and per-person amounts without a phone-argument.
- You are splitting unevenly — one person had the lobster — and need a fair framework fast.
- Takeout, bar or delivery norms differ from sit-down and you want the math for a chosen percent.
- You are checking what 'just add tax' mental shortcuts get wrong.
How to use it, step by step
- Enter the bill amount.
- Choose the tip percent (the presets cover the standard 15/18/20/25%).
- Set the number of people splitting.
- Read tip, total and each person's share.
- Round your own share up if you ordered the extra appetizer — the table will notice.
What the inputs mean
| Input | What it is | Typical values |
|---|---|---|
| Bill amount | The check total (pre-tip) | Use the pre-tax subtotal for the classic method |
| Tip % | The rate you choose | 15% standard, 18–20% good service, 25%+ generous |
| People | Ways the total splits | Even split assumed |
Another worked example
An $86.40 bill at 20% split three ways: the tip is $17.28, the total $103.68, and each person owes $34.56. The classic shortcut — double the tax on a ~10% tax bill — lands within a dollar of the 20% figure, which is why it survives as a rule of thumb.
Frequently asked questions
What is the standard tip at a restaurant?
In the US, 18–20% is the standard for good sit-down service, 15% for adequate service, and 20–25% for exceptional service. For bars, $1–2 per drink is typical.
Should we split the bill evenly or itemize?
Even splits are fastest and fairest when everyone ordered similarly. If one person ordered far more, itemize their share first, then split the rest evenly.
Do I tip on the pre-tax or post-tax amount?
Traditionally you tip on the pre-tax subtotal, though many people tip on the total for simplicity. The difference is small — pick one and stay consistent.
Do I tip on the pre-tax or post-tax amount?
Tradition says pre-tax subtotal; many people tip on the total for simplicity. On an $86.40 bill with 8% tax the difference at 20% is about $1.28 — consistency and generosity matter more than the convention.
What about tipping on takeout or coffee?
Customs have shifted toward small tips (10% or a dollar or two) for counter service, but they remain optional in a way table service is not — no server is working your table for a sub-minimum tipped wage. Set the percent here to whatever you decide; the math is neutral.
