Split Bill Calculator — input your values
What does this everyday calculator do?
The split bill calculator divides a restaurant or group bill among any number of people, adding both tax and tip to the total before splitting.
It shows the tax amount, the tip amount and the final per-person share, plus a donut chart of how the total is composed, so everyone at the table can verify the math.
Formula and variables
When some people order more than others, an equal split still works — the group just accepts a shared average.
| Symbol | Meaning |
|---|---|
| Tax | bill × tax percentage ÷ 100 |
| Tip | bill × tip percentage ÷ 100 (pre-tax) |
| Per person | grand total ÷ number of people |
Worked example
A group of four dines out with a $160 bill, 8% tax and an 18% tip.
- Tax = $160.00 × 0.08 = $12.80.
- Tip = $160.00 × 0.18 = $28.80.
- Total = $160.00 + $12.80 + $28.80 = $201.60.
- Per person = $201.60 ÷ 4 = $50.40.
Answer: Each of the four diners pays $50.40.
Tips and common mistakes
Tips
- Round each person's share up to the nearest dollar and keep the difference as the tip if the group is happy with service.
- If one person had no alcohol or dessert, consider an itemized split rather than an equal split to keep it fair.
- Set the tax to the local rate for your area (many US states are between 5% and 10%) for an accurate total.
- When splitting with a payment app, use the per-person figure from the calculator and note any app fees.
Common mistakes to avoid
- Tipping on the post-tax total while the calculator uses pre-tax, which changes the total by a few dollars.
- Forgetting to include tax in the split, leaving the payer of the card to absorb it.
- Entering the number of people as the number of bills instead of the number of diners.
Split Bill Calculator — frequently asked questions
How do I split a bill fairly?
Add tax and tip to the bill, then divide by the number of people. The calculator does all four steps and shows the per-person share.
Should the tip be calculated before or after tax?
In the US, the tip is conventionally 15% to 20% of the pre-tax bill. This calculator follows that convention and notes it in the results.
What if people ordered different amounts?
An equal split is simplest, but for fairness you can mentally adjust the shares — the total including tax and tip stays the same.
How do I handle a service charge already on the bill?
If a gratuity is already included, set the tip percentage to 0 so you do not tip twice.
What is the difference between this and the tip calculator?
This calculator adds tax and tip together and splits the full total among a group. The tip calculator focuses on the tip amount itself, with splitting as an option.
Can I split unevenly between people?
Not directly — this tool divides evenly. For uneven splits, calculate the total here, then redistribute the shares however the group agrees.
