Common Mistakes
Problem
Expecting an uneven or itemized split
Solution
This calculator only splits the bill evenly across the Number of People field - there is no way to assign different amounts to people who ordered differently.
Problem
Not deciding pre-tax vs. post-tax before entering the bill
Solution
There is no tax field or toggle - the tool tips on whatever amount you type into Bill Amount, so decide up front whether that figure already includes tax.
Problem
Expecting a rounding option
Solution
Results are formatted to 2 decimal places for display only - there is no round-up-to-nearest-dollar or similar rounding mode.
Problem
Missing the per-person cards on a single-person bill
Solution
Tip Per Person and Total Per Person only appear when Number of People is greater than 1.
Tips & Best Practices
Decide pre-tax or post-tax before you start
Since the calculator has no tax field, be consistent about entering either the pre-tax or post-tax bill amount depending on your own convention.
Use Custom for percentages between the presets
If you want something like 12% or 22%, click Custom instead of rounding to the nearest preset button.
Double-check the people count for uneven groups
The Number of People field rounds to the nearest whole number, so entering a fraction like 2.5 will not produce a partial split.
Compare presets side by side before deciding
Click through the 10-25% presets to see how the total changes before settling on what to leave.
Limitations
Even split only
The tool divides the bill and tip equally across the number of people entered - it has no itemized or unequal per-person split mode.
No tax handling
There is no tax field or pre-tax/post-tax toggle - the tip is calculated on exactly the bill amount you enter, with no adjustment for sales tax.
No rounding mode
Results are shown to 2 decimal places for display only - there is no option to round the total or per-person amounts up or down.
No currency selector
Results are displayed with a fixed $ symbol - there is no dropdown to switch to another currency.
No saved history
Each calculation is a one-time result on the page - nothing is saved between visits or across bills.
Comparisons
Preset Tip vs. Custom Tip
Both calculate the same way - only how you enter the percentage differs.
| Preset (10/15/18/20/25%) | Custom Percentage | |
|---|---|---|
| How you set it | Click one of five preset buttons | Click Custom and type any percentage |
| Best for | Common tip rates without typing | Non-standard rates like 12% or 22% |
| Calculation used | Same formula: bill × percentage ÷ 100 | Same formula: bill × percentage ÷ 100 |
Which should you use?
The presets exist purely for convenience - a custom percentage produces results through the identical calculation, so use whichever entry method is faster for the rate you want.
FAQs
The most common question is what tip percentage to leave. In the US, a commonly cited range is roughly 10% for basic service, 15–18% for standard service, 20% for great service, and 25% for exceptional service - though this varies by region, service type, and personal judgment. In many other countries, tipping is not standard at all, so check local customs before assuming a US-style percentage applies.
What tip percentages are standard?
Common tip rates are 10% for basic service, 15–18% for standard service, 20% for great service, and 25% for exceptional service.
Can I use a custom tip percentage?
