Tip Calculator
Calculate gratuity, service charge, total bill, and per-person split without mixing up subtotal, tax, and tip basis.
Tip Calculator
A tip calculator helps you separate the parts of a bill that often get mixed together: subtotal, tax, service charge, and the extra gratuity you actually choose to add. That matters because a service charge is not always the same thing as a voluntary tip, and a group split is easier when everyone can see the full breakdown.
What This Calculator Covers
- Percentage-based tipping.
- Fixed-amount tipping.
- Even bill splitting across one or more people.
- Separate tax and service-charge handling.
- Different tip bases such as subtotal only, subtotal plus tax, or a custom base.
How to Use the Tip Calculator
- Enter the subtotal for the bill.
- Add tax if you want the calculator to keep the tax portion separate.
- Enter a service charge amount or service-charge rate if one is already added.
- Choose whether you want to leave a percentage tip or a fixed tip.
- Pick the tip basis and the number of people sharing the bill.
- Review the additional tip, grand total, and per-person amount.
Tip Formulas
Service charge = Fixed service charge amount
or
Service charge = Subtotal x (Service charge rate / 100)
Additional tip = Tip base x (Tip percent / 100)
or
Additional tip = Fixed tip amount
Grand total = Subtotal + Tax + Service charge + Additional tip
Per person = Grand total / Split count
Example Tip Calculation
Suppose the subtotal is $84.00, tax is $6.72, service charge is 10%, and you want to leave an 18% tip on subtotal + tax.
| Item | Value |
|---|---|
| Subtotal | $84.00 |
| Tax | $6.72 |
| Service charge | $8.40 |
| Additional tip | $16.33 |
| Grand total | $115.45 |
If 4 people split that total evenly, each person pays $28.86.
Why the Breakdown Matters
Service charge is not always the same as a tip
Some venues add service automatically before you decide whether to leave anything extra.
Tip basis changes the result
Tipping on subtotal only produces a different number than tipping on subtotal plus tax.
Group splits are easier when the total is explicit
A clear per-person amount reduces awkward rounding and double counting.
Local custom still matters
The calculator handles the arithmetic, but etiquette depends on where you are and what service you received.

FAQs
What does the service charge field do?
It lets you separate an amount already added to the bill from the extra gratuity you may still want to leave.
Should I tip on tax too?
That depends on local practice and personal preference. The calculator supports subtotal-only and subtotal-plus-tax approaches so the basis stays explicit.
Can I leave a flat tip instead of a percentage?
Yes. Fixed-tip mode is useful when you want to add a specific amount regardless of the bill percentage.
What if only one person is paying?
Set the split count to 1. The calculator will still show the full total without changing the math.
Why does my final split not match a receipt exactly?
The venue may round differently, include other charges, or split items unevenly before the gratuity is applied.
