Calculate a custom tip, choose whether it applies before or after tax, account for a service charge, round the result and split the final bill equally between multiple people.
Enter the amounts shown on the receipt, choose a tip percentage and decide what amount the tip should be based on. The calculator immediately shows the tip, final total and each person's equal share.

What the Tip Calculator Does
This calculator separates the receipt into subtotal, tax, mandatory service charge and voluntary tip. It can calculate the tip from the pre-tax subtotal, the after-tax amount or the complete pre-tip bill, then divide the final total equally.
Calculate gratuity
Use a quick percentage or enter any custom rate, including zero.
Check added charges
Keep tax and mandatory service charges visible instead of silently treating them as a tip.
Split the total
See the bill share, voluntary tip and final payment for each person.
The result updates as values change and runs entirely in the browser. No receipt or payment information is sent to 1Dollars.
How to Calculate a Tip
The basic formula multiplies the chosen tip base by the selected percentage:
Next, add the tip to the complete pre-tip bill:
To divide the bill equally, divide both the final total and tip by the number of people. The displayed per-person total is rounded to two decimal places, so collecting individually rounded shares can differ from the exact total by a few minor currency units.
Should a Tip Be Calculated Before or After Tax?
There is no single worldwide convention. Some customers calculate a percentage from the pre-tax subtotal, while others use the after-tax total shown on the receipt. This tool supports both methods without choosing one for you.
- Subtotal only: excludes tax and mandatory service charges from the percentage base.
- Subtotal plus tax: applies the percentage to the after-tax amount.
- All charges: applies it to subtotal, tax and the entered service charge.
Before paying, verify whether the receipt's suggested tip figures are based on the pre-tax or after-tax amount. Two receipts with the same subtotal can produce different suggested tips when their tax treatment differs.
Tips and Mandatory Service Charges Are Different
A voluntary tip is chosen by the customer. A mandatory service charge or automatic gratuity is imposed by the establishment. Under U.S. federal labor guidance, a compulsory charge is not considered a tip under the Fair Labor Standards Act. The U.S. Department of Labor's tipped-employee fact sheet explains this distinction.
The IRS similarly distinguishes customer-controlled voluntary tips from required service charges. Distribution to workers can vary, so the calculator never subtracts an entered service charge from the voluntary tip automatically. Check the receipt or ask the establishment what the charge covers.
Practical check: Look for terms such as “service charge,” “automatic gratuity,” “hospitality charge” or “large-party charge.” Decide whether to add a separate voluntary tip only after understanding the existing charge.
How to Split a Restaurant Bill Equally
- Enter the full bill subtotal, tax and mandatory service charge.
- Select a tip base and percentage.
- Enter the number of people sharing the payment.
- Use “Each person pays” for an equal split.
An equal split is simple but may not feel fair when individual orders differ substantially. In that situation, calculate each person's items and share of tax/service charge separately, then apply the chosen tip method to each portion.
Rounding a Tip or Final Total
The calculator offers two optional upward-rounding methods:
- Round tip up: raises only the tip to the next whole currency unit.
- Round final total up: increases the tip just enough to make the complete total a whole currency unit.
The result card shows the difference between the unrounded percentage tip and the final rounded tip. When splitting a bill, rounding the combined total first is usually clearer than independently rounding every person's amount.
Tip Calculation Examples
| Scenario | Tip base | Rate | Tip | Final total |
|---|---|---|---|---|
| USD 85 subtotal + USD 7.23 tax | USD 85.00 subtotal | 20% | USD 17.00 | USD 109.23 |
| EUR 60 subtotal + EUR 6 tax | EUR 66.00 after tax | 15% | EUR 9.90 | EUR 75.90 |
| GBP 120 subtotal + GBP 15 service charge | GBP 120.00 subtotal | 10% | GBP 12.00 | GBP 147.00 |
Default equal-split example
For a USD 85.00 subtotal, USD 7.23 tax, no service charge and a 20% tip on the subtotal:
Tipping Practices Vary by Place and Service
The preset percentages are arithmetic shortcuts, not a statement that a particular rate is required. Customs vary by country, city, venue, service type, party size and whether a service charge is already included. Some places discourage tipping; others commonly display suggested percentages.
Use the selected currency code only for labeling—it does not establish a local tipping custom or perform foreign-exchange conversion. Travelers can find additional country-specific tools in the Global Calculators directory.
Methodology and Accuracy
The calculator uses decimal arithmetic from the entered values, applies the selected percentage to one of three bases, optionally rounds upward, and divides the final amount equally. Displayed money values use two decimal places, while internal calculations retain additional precision until output.
It does not determine local etiquette, employee distribution, tax consequences, card-processing treatment or whether a service charge replaces a tip. The service-charge distinction was reviewed against current U.S. Department of Labor and IRS guidance on July 19, 2026.
Editorial review: Formula cases were tested for zero tip, custom percentages, before-tax and after-tax bases, service charges, rounding and multi-person splits. Calculations are educational and should be checked against the actual receipt.
Tip Calculator FAQs
How do I calculate a 20% tip?
Multiply the chosen tip base by 0.20. For a USD 85 subtotal, the calculation is 85 × 0.20 = USD 17. Add that tip to tax, service charge and subtotal for the final total.
Should I calculate the tip before or after tax?
Practices vary. Choose “Bill subtotal only” for a pre-tax tip or “Subtotal plus tax” for an after-tax calculation. Check what the receipt's suggested figures use.
Is a service charge the same as a tip?
Not necessarily. A mandatory service charge is imposed by the establishment, while a tip is voluntarily chosen by the customer. Confirm what the charge covers and whether workers receive it.
How do I split a bill with a tip?
Add subtotal, tax, service charge and tip, then divide the final total by the number of people. This tool also shows each person's equal bill share and tip share.
Can I enter a custom tip percentage?
Yes. Enter any nonnegative percentage in the custom field. The quick buttons simply provide common calculation values and are not recommendations.
What does “round tip up” mean?
It increases the calculated tip to the next whole currency unit. A calculated tip of 17.01 becomes 18.00 in the selected currency.
What does “round final total up” mean?
It increases the voluntary tip enough to make the complete bill a whole currency unit. A total of 109.23 becomes 110.00.
Does the calculator convert currencies?
No. The selected currency code labels results only. Enter every amount in the same currency and use a separate exchange-rate tool when conversion is needed.
Why can the per-person shares differ slightly from the total?
Each displayed share is rounded to two decimal places. Multiplying a rounded share by the number of people can differ from the exact total by a few minor currency units.
Are tips taxable income in the United States?
The IRS generally treats tips received by workers as income and provides reporting rules. This customer-facing calculator does not calculate worker taxes or employer payroll obligations.
