Common Tip Amounts
Every amount is calculated to the exact cent. You type every figure: no tip percentage is suggested or preselected, no tax is assumed, no choice between before and after tax is made for you, and no charge is added unless you enter it. The tool does arithmetic only.
Bill & tip
The bill, the tax, the base of the tip and the voluntary tip, with any additional charge you enter. A service charge is a charge, not a tip: it is kept apart from the tip.
Split bill
Share the check and the tip among up to 50 people. When an amount does not divide into whole cents, the spare cents are given one at a time by the largest remainder, in a fixed order, so the shares always add up to the total exactly. If your own shares do not add up, the tool shows the gap and asks you to correct it: it never rebalances them silently.
Tip pool
Divide an amount of tips among the people you list, equally, by the hours you type or by the points you type. Hours, points, roles and eligibility are never assumed.
This tool performs a mathematical division. It does not check whether employees are eligible for a pool or whether your practices comply with the rules that apply to you, and the shares shown are not net pay.
Compare two scenarios
Scenario A is what you entered above for the thing you compare, and it is never changed. Describe scenario B by typing only what differs: an empty field keeps A’s value. A person or an employee can be changed or removed in B only, or added in B only; an added person is a new person, never a moved one.
The bill
Type either a percentage or an amount, not both. 0 is allowed. The voluntary tip is yours to decide: nothing is suggested.
Additional charges (optional)
Only if your check has them, for example a service charge or a delivery fee. Each is named and typed by you. A charge is never a tip, and it is in the tip base only if you tick the box.
The people
Equal sharing needs only the number of people. “By amounts” needs each person’s exact share and the shares must add up to the check exactly. “By weights” divides the check in proportion to the weights you type.
The pool
Scenario B: only what differs
For each person of A, type only what changes in B, or tick “Remove in B”. A person added with the button below exists only in B.
For each employee of A, type only what changes in B, or tick “Remove in B”. An employee added with the button below exists only in B.

What Is a Restaurant Tip Calculator?
A restaurant tip calculator works out the tip on a bill and the total once the tip is added. This one has two modes. Simple is the quick calculator at the top of the page: a bill, a tip percentage, optional tax and a split between people. Tip Studio is the advanced mode, with four separate spaces: Bill & tip, Split bill, Tip pool and Compare.
Studio counts in whole cents. A percentage is rounded once, to the nearest cent with halves rounded up, and an amount shared among people is split so the shares always add up to the amount, to the cent. Studio does not start from a tip percentage, a tax base or a pool method: you enter or choose each one, and it asks when one is missing.
Which part do you need?
- A tip and a total on one bill, or an even split between friends: Simple mode, or Bill & tip in Studio.
- A table where each person owes a different amount: Split bill, by amounts or by weights.
- A manager dividing tips between employees at the end of a shift: Tip pool, equally, by hours or by points.
- Two ways of doing the same thing, side by side: Compare.
Every figure on this page, in the examples and in the FAQ, is produced by the same calculation engine that Studio uses. The examples are illustrations, not recommendations, and the tool does arithmetic only: it is not legal, tax or payroll advice.
The math
Restaurant Tip Formula
A percentage tip is the tip base multiplied by the percentage. The total is the bill, plus any tax, plus any additional charge, plus the tip.
The formula
Tip Base × Tip Percentage = Tip Amount
Example: $80.00 × 20% = $16.00 tip, $96.00 total.
How to Calculate a Restaurant Tip
Four amounts are easy to mix up, so keep them apart. The bill is the food and drink on the check. The tax is the sales tax. The tip is the voluntary amount you add. The total is what is paid in the end.
Tip as a percentage
Multiply the tip base by the percentage, then add the result to the bill. An $80.00 bill with a 20% tip gives a $16.00 tip and a $96.00 total: $80.00 × 20% = $16.00, and $80.00 + $16.00 = $96.00. The percentage is yours to choose. Studio suggests none and starts empty.
Tip as a fixed amount
A fixed tip is a number of dollars you type. It has no percentage and no tip base. With a $100.00 bill and 8.25% tax, a fixed $18.00 tip gives a total of $126.25: the bill ($100.00), the tax ($8.25) and the tip ($18.00).
Bill, tax, tip and total in one example
| Line | Percentage tip: 20% of the bill | Fixed tip: $18.00 |
|---|---|---|
| Bill | $100.00 | $100.00 |
| Tax (8.25% of the bill) | $8.25 | $8.25 |
| Voluntary tip | $20.00 | $18.00 |
| Total | $128.25 | $126.25 |
The tax is the bill times the rate, rounded once to the cent. In Studio, enter it either as a rate or as the amount printed on your check, not both.
Before-Tax vs After-Tax Tips
The tip base is the amount the percentage is applied to. There are two common bases. Neither is required or universal: the choice is yours, so Studio asks for it as soon as you enter tax and never picks one for you.
- Before tax: the tip is calculated on the bill alone. Tax is added afterwards.
- After tax: the tip is calculated on the bill plus tax.
| Line | Tip before tax | Tip after tax | Difference |
|---|---|---|---|
| Tax | $8.25 | $8.25 | $0.00 |
| Tip base | $100.00 | $108.25 | $8.25 |
| Tip (20%) | $20.00 | $21.65 | $1.65 |
| Total | $128.25 | $129.90 | $1.65 |
Tax as a rate or as an amount
A tax rate is applied to the bill: 8.25% of $100.00 is $8.25. A tax amount is the figure printed on your check. Entering $8.25 as an amount gives exactly the same result here. Use the amount when the check shows a tax that a single rate would not reproduce, for example when several rates apply to different items.
How to Split a Restaurant Bill
Studio splits two things separately: the check (bill, tax and any additional charge) and the tip. You can share up to 50 people's checks in three ways.
- Equally: the check divided by the number of people.
- By amounts: you type what each person owes. The amounts must add up to the check.
- By weights: you type a weight for each person, and each share is that weight divided by the total of the weights.
The tip can be shared equally, in proportion to the check or by exact amounts you type.
Example with three people
A $90.00 bill with a 20% tip ($18.00), no tax, shared by three people.
| Method | Ana | Ben | Cy | Sum of totals |
|---|---|---|---|---|
| Check and tip equal | $36.00 | $36.00 | $36.00 | $108.00 |
| Check by amounts ($40, $30, $20), tip in proportion | $48.00 | $36.00 | $24.00 | $108.00 |
| Check by weights (1, 2, 3), tip equal | $21.00 | $36.00 | $51.00 | $108.00 |
Each total is a share of the check plus a share of the tip. The control sum is always shown: here, $90.00 of check plus $18.00 of tip, $108.00 in all.
When custom shares do not add up
If you type $40.00, $30.00 and $15.00 for a $90.00 check, the shares add up to $85.00. Studio shows that the shares are $5.00 short and asks you to correct them. It never rebalances them for you, because it cannot know who owes the difference.
How to Divide Tips Without Losing Cents
Money has no amounts smaller than a cent, so some divisions do not come out even. $100.00 divided by 3 is $33.333… Rounding every share on its own gives $33.33 three times, which adds up to $99.99: a cent has disappeared. The same happens in the other direction, when rounding creates a cent.
The method Studio uses
- Each person first gets their share rounded down to a whole cent.
- The cents left over, always fewer than the number of people, are given out one at a time to the people whose exact share had the largest fractions.
- If fractions are equal, the cents go in a fixed order that starts with the first person and moves on after each spare cent, so the same entries always give the same result.
This is one consistent convention. It is not presented as the only fair way to divide spare cents, and a group can agree on another.
| Example | First share | Second share | Third share | Sum |
|---|---|---|---|---|
| $100.00 bill among 3 people | $33.34 | $33.33 | $33.33 | $100.00 |
| $10.00 of tips among 3 employees | $3.34 | $3.33 | $3.33 | $10.00 |
In both examples one spare cent exists and goes to the first person. In Studio the table marks who received a spare cent, and says whether it came from the check or from the tip.
The simple calculator also keeps every cent. It shares the tip and the total each in whole cents, and gives the spare cents one at a time to the first people, so $100.00 among 3 people shows $33.34 for 1 person and $33.33 for each of the other 2, which adds up to exactly $100.00. The tip per person and the total per person are each shared on their own, and each set of shares adds up to its own amount.
How to Calculate a Tip Pool
A tip pool is an amount of tips divided among the people you list. In Studio, enter the pool total, the number of employees, and choose a method. No method is preselected.
- Equally: every listed person gets the same share.
- By hours: each share is that person's hours divided by everyone's hours.
- By points: each share is that person's points divided by everyone's points.
Hours and points are only what you type. Studio does not assume hours, roles, points or eligibility.
| Employee | Hours typed | Share by hours | Points typed | Share by points |
|---|---|---|---|---|
| Ana | 30 | $120.00 | 3 | $85.72 |
| Ben | 20 | $80.00 | 2 | $57.14 |
| Cy | 0 | $0.00 | 2 | $57.14 |
| Total distributed | 50 | $200.00 | 7 | $200.00 |
With points the exact shares are not whole cents, so one spare cent goes to Ana, who had the largest fraction. The shares still add up to $200.00. The employee with zero hours has a weight of zero and gets $0.00. That is arithmetic, not a judgment on anyone.
When every weight is zero
If every hour value is 0, there is nothing to divide by. Studio shows an error and does not switch silently to an equal split. Type at least one value above 0, or choose the equal method.
This is a mathematical division. It does not check whether employees are eligible for a tip pool or whether your practices comply with the rules that apply to you. The shares are gross amounts of tips, not net pay: no wage, tax or withholding is calculated.
Compare Two Tip or Split Methods
The Compare space keeps your entries as scenario A and lets you type only what differs in scenario B. A is never changed. You can compare a bill with a tip, a split, or a pool, and Studio shows A, B and the difference in dollars.
Bill: tip before tax or after tax
With the $100.00 bill, 8.25% tax and 20% tip, A calculates the tip before tax and B after tax. The tip goes from $20.00 to $21.65 and the total from $128.25 to $129.90, a difference of $1.65.
Split: a different tip
With the $90.00 bill split equally among 3 people, A has a 20% tip and B a 25% tip. Each person pays $36.00 in A and $37.50 in B, $1.50 more. The totals are $108.00 and $112.50.
Pool: an employee removed and another added
| Employee | Hours in A | Share in A | Hours in B | Share in B | Status |
|---|---|---|---|---|---|
| Ana | 30 | $100.00 | 30 | $100.00 | unchanged |
| Ben | 20 | $66.67 | — | — | removed in B |
| Cy | 10 | $33.33 | 10 | $33.33 | unchanged |
| Dee | — | — | 20 | $66.67 | added in B |
| Total | 60 | $200.00 | 60 | $200.00 |
Dee receives the share Ben had, yet Dee is a new employee, not Ben moved: Ben stays in A, with no share in B, and Dee has no share in A. Studio keeps them apart so you do not read it as one person changing.
The limit of comparing by position
Studio matches people and employees by their place in the list, not by name. If B changes a name in a place, it is the same position with a new entry. People added in B come after the last place of A, and removing someone in B does not shift the others up. If you reorder the list in A, check the comparison again.
Tips vs. Service Charges
A voluntary tip is an amount the customer decides to add. A service charge is a charge the restaurant puts on the bill. They are different things, so Studio never turns one into the other.
In Studio, a charge appears only if you add it, with the name you give it. It has its own line, apart from the tip, and it is never counted as a tip. You decide whether it is part of the tip base. The tool decides nothing about its tax or legal treatment.
| Line | Charge not in the tip base | Charge in the tip base |
|---|---|---|
| Bill | $100.00 | $100.00 |
| Service charge (a charge, not a tip) | $15.00 | $15.00 |
| Tip base | $100.00 | $115.00 |
| Voluntary tip (20%) | $20.00 | $23.00 |
| Total | $135.00 | $138.00 |
Whether a restaurant's bill already includes a service charge, and what happens to it, depends on that restaurant and on the rules that apply to it. Check your bill and ask the restaurant. This page makes no claim about the rules.
Common Mistakes and Limitations
- Confusing the total with the amount before tax. A percentage applied to a total that already includes tax is a tip after tax. Choose the base on purpose.
- Forgetting to choose the tip base. Studio asks as soon as tax is entered, instead of assuming.
- Adding shares that were rounded separately. Three shares of $33.33 add up to $99.99. Share the amount with the spare cents, as in the section above.
- Treating a service charge as a tip. They are separate lines with separate meanings.
- Assuming a mathematical pool is automatically allowed. The tool divides numbers. It does not check eligibility or compliance.
- Reading a pool share as pay. A share is a gross amount of tips. It is not net pay and includes no tax or withholding.
- Expecting the simple calculator and Studio to match exactly. The simple mode starts with 20%, a pre-pressed 20% chip, 2 people and the tip after tax. Studio starts empty. Both count in whole cents, but the simple mode shares the tip and the total each on their own among equal shares, while Studio can also split a bill by amounts or weights. Results can differ when the starting values, the tip base or the split differ.
Studio limits: bills up to $1,000,000,000,000.00, percentages from 0 to 1000 with at most four decimals, 50 people, 50 employees and 5 additional charges. Amounts with more than two decimals, negative amounts and exponents are refused rather than rounded.
For restaurant teams
Tip Math for
Operators
Managers use the same arithmetic to check a bill, to divide an amount of tips at the end of a shift or to test a scenario before changing a practice. The tool only does the math. It does not decide who is eligible, which methods the rules that apply to you allow, or how amounts are paid.
Dividing a tip pool and analyzing labor costs are two different uses. The Restaurant Labor Cost Calculator has its own definition of total labor cost, and this page draws no conclusion about how tips are treated for accounting, tax or legal purposes. To look at your results as a whole, use the Restaurant Profit Calculator. To price a dish, use the Menu Price Calculator.

Good to know
Frequently Asked Questions
How do you calculate a restaurant tip?
Multiply the tip base by your percentage, or type a fixed dollar amount, then add the tip to the bill and any tax. A 20% tip on an $80.00 bill is $16.00, so the total is $96.00. Tip Studio suggests no percentage: it starts empty and uses the one you enter.
Should a tip be calculated before or after tax?
Both are used, and neither is required everywhere. On a $100.00 bill with 8.25% tax, 20% before tax is $20.00 and 20% after tax is $21.65, a difference of $1.65. Tip Studio asks you to choose the base whenever tax is entered, and never picks one for you.
Should I enter tax as a rate or as an amount?
Either. A rate is applied to the bill and rounded once to the cent: 8.25% of $100.00 is $8.25. An amount is the figure printed on your check, useful when one rate would not reproduce it. Entering both for the same tax is refused, so the tool never chooses between them.
How do I split a bill when people ordered different amounts?
Choose custom amounts and type what each person owes, or give each person a weight. Custom amounts must add up to the check. If $40.00, $30.00 and $15.00 are entered for a $90.00 check, Studio reports the $5.00 gap and waits for a correction instead of adjusting anyone's share.
How can the tip be shared when a bill is split?
Three ways: equally, in proportion to each person's share of the check, or by exact amounts you type. With an $18.00 tip and checks of $40.00, $30.00 and $20.00, the proportional tips are $8.00, $6.00 and $4.00. Exact amounts must add up to the tip, as custom check shares must add up to the check.
What happens to the leftover cents when a division is not exact?
$100.00 among 3 people cannot be three equal amounts, so Studio shows $33.34, $33.33 and $33.33. Everyone gets their share rounded down, then spare cents go one at a time to the largest fractions in a fixed order. The shares always add up to the amount. It is one consistent convention, not the only fair one.
Is a service charge the same as a tip?
No. In Studio a service charge is a charge you name and enter, shown on its own line and kept out of the tip. Whether it joins the tip base is your choice: with a $15.00 charge on a $100.00 bill, a 20% tip is $20.00 without it and $23.00 with it. The tool does not decide its tax or legal treatment.
How does a tip pool calculation work?
Enter the pool total, list the employees and choose equally, by hours or by points. Each share is a person's hours or points divided by everyone's. A $200.00 pool with 30, 20 and 0 hours gives $120.00, $80.00 and $0.00. With points of 3, 2 and 2 it gives $85.72, $57.14 and $57.14.
What happens when hours or points are zero?
A person with zero hours or points has a weight of zero and gets $0.00. If every weight is zero, no division is possible, so Studio reports an error and does not fall back to an equal split. Hours and points are only what you type. Nothing is assumed about roles or schedules.
Can I compare two ways of splitting or pooling?
Yes. In the Compare space your entries stay as scenario A, and you change only what differs in B. B never alters A. People and employees are matched by their place in the list, so one removed and another added in B appear as removed and added, not as a single person who changed.
Does the calculator check whether a tip pool is allowed?
No. It divides numbers. It does not check who may take part in a pool, whether a method complies with the rules that apply to you, or what tax is owed. A pool share is a gross figure of tips, never net pay. For those questions, ask the authority or adviser that applies to you.
Why can the simple calculator and Tip Studio show different results?
The simple calculator starts with a 20% preset and the tip after tax, and Studio starts empty, so the same bill can differ when the percentage or the tip base differs. Both keep every cent: split three ways, a $100.00 total gives one person $33.34 and the two others $33.33 in either mode, for exactly $100.00. In the simple calculator, the spare cents go to the first people. Neither is a recommendation.
