About the Tip Calculator
Work out the tip, add it to the bill, and split the result between however many people are paying. This calculator does all three, and shows the tip per person alongside the total per person so everyone can see what they are contributing.
The rounding option is the part people actually use. Round up per person and everyone pays a whole amount — no counting out small change at the table. Round up the total instead and the bill lands on a clean figure. Either way the tip adjusts to match, and the tool shows what it became.
It works in any currency, since percentages do not care about units. Enter the bill in whatever you are paying in.
How to use the Tip Calculator
- Enter the bill amount as printed, before any tip.
- Set the tip percentage with the slider, or tap one of the quick-pick buttons.
- Enter how many people are splitting the bill.
- Optionally choose a rounding mode to lift each share to a whole unit.
- Select Calculate tip. The effective tip shows what you actually ended up leaving after rounding.
The tip calculator formula
Tip = bill × (tip% ÷ 100)
Total = bill + tip
Per person = total ÷ number of people
Worked example
A bill of £87.40, tipping 18%, split between 4 people.
Tip: 87.40 × 0.18 = £15.73
Total: 87.40 + 15.73 = £103.13
Per person: 103.13 ÷ 4 = £25.78
£25.78 each — or £26 each with rounding, lifting the tip to £16.60
Quick tip percentages
| Bill | 10% | 15% | 18% | 20% | 25% |
|---|---|---|---|---|---|
| £25 | £2.50 | £3.75 | £4.50 | £5.00 | £6.25 |
| £50 | £5.00 | £7.50 | £9.00 | £10.00 | £12.50 |
| £75 | £7.50 | £11.25 | £13.50 | £15.00 | £18.75 |
| £100 | £10.00 | £15.00 | £18.00 | £20.00 | £25.00 |
| £150 | £15.00 | £22.50 | £27.00 | £30.00 | £37.50 |
Two mental shortcuts worth having. For 10%, move the decimal one place left. For 20%, do that and double it. Fifteen per cent is 10% plus half of it again.

No phone handy? Find your bill in the left column and read across. It works as a quick restaurant tip calculator and a 20% tip calculator in one.
| Bill | 15% | 18% | 20% | 25% |
|---|---|---|---|---|
| $20 | $3.00 | $3.60 | $4.00 | $5.00 |
| $30 | $4.50 | $5.40 | $6.00 | $7.50 |
| $40 | $6.00 | $7.20 | $8.00 | $10.00 |
| $50 | $7.50 | $9.00 | $10.00 | $12.50 |
| $60 | $9.00 | $10.80 | $12.00 | $15.00 |
| $75 | $11.25 | $13.50 | $15.00 | $18.75 |
| $100 | $15.00 | $18.00 | $20.00 | $25.00 |
| $150 | $22.50 | $27.00 | $30.00 | $37.50 |
| $200 | $30.00 | $36.00 | $40.00 | $50.00 |
For a 15% tip, take the 10% figure and add half of it again. For 25%, take a quarter of the bill.
How much to tip, and where
Tipping norms vary enormously by country, and getting them wrong in either direction is awkward. Broad guidance:
| Country | Restaurant norm | Notes |
|---|---|---|
| United States | 15–20% | Expected; staff wages often assume it |
| Canada | 15–20% | Similar to the US |
| United Kingdom | 10–15% | Often a discretionary service charge instead |
| Much of Europe | 5–10% | Frequently just rounding up |
| Japan | None | Tipping can cause genuine offence |
| Australia, NZ | Optional | Not expected; appreciated for good service |
Beyond restaurants, other services have their own conventions — hairdressers and barbers, tattoo artists, taxi drivers, delivery riders and hotel staff are all commonly tipped where tipping is customary at all, typically in the 10–20% range. When in doubt, ask a local rather than guessing.
These are broad norms, not rules, and they shift over time. In the US in particular, prompted tip suggestions on card terminals have pushed expected percentages upward in recent years. Tip what you think the service was worth, within local convention.
Tipping on the pre-tax or post-tax total
Both are defensible, and the difference is small. Tipping on the pre-tax amount is arguably more logical, since tax is not part of the service. Tipping on the post-tax total is simpler, because it is the number printed at the bottom of the bill.
On a £100 bill with 8% tax, tipping 20% pre-tax gives £20 and post-tax gives £21.60. A pound and change is not worth agonising over — but if you want the pre-tax figure, enter the subtotal rather than the total.
When service charge is already included
Check the bill before tipping again. Many restaurants add a service charge automatically, particularly for larger groups, and it is often 12.5% in the UK or 18–20% for parties in the US.
- If service charge is included, no further tip is expected. Adding more is a bonus for genuinely good service.
- If it is discretionary, you can usually ask for it to be removed — and tip in cash instead if you prefer the staff receive it directly.
- Ask where it goes. Practice on whether service charge reaches staff varies by venue and jurisdiction.
How rounding changes the tip
Rounding up per person is convenient but it is not free — it raises the tip, sometimes noticeably. On the £87.40 bill split four ways, rounding £25.78 up to £26 each adds £0.87 to the tip, taking the effective rate from 18% to 19%.
With more people the effect grows, since each person rounds up separately. Split ten ways, the same rounding could add several pounds. The calculator always shows the tip after rounding so you can see where you have landed.
For percentage work generally, the percentage calculator covers increases, decreases and reverse calculations. For adding or removing sales tax, see the VAT calculator.
How much to tip for services (US guide)
Restaurants are only part of the story. Here are common US tipping ranges for other services. Use the slider above to apply any percentage.
| Service | Typical tip | Example on $60 |
|---|---|---|
| Haircut or hair stylist | 15–20% | $9–$12 |
| Nail salon, manicure, pedicure | 15–20% | $9–$12 |
| Tattoo artist | 15–25% | $9–$15 |
| Food delivery | 15–20%, at least $3–$5 | $9–$12 |
| Taxi or rideshare | 15–20% | $9–$12 |
| Restaurant table service | 15–20% | $9–$12 |
For a hair colour or long tattoo session, tip on the full price, not just the cut or one hour. If several people worked on you — say a washer and a stylist — split the tip between them.
Tax and tip calculator: which total to use
Etiquette guides generally say to tip on the pre-tax amount, since tax is not part of the service. Many people tip on the after-tax total anyway because it is the number printed at the bottom. The difference is small — on a $60 meal with 8% tax, a 20% tip is $12.00 pre-tax or $12.96 after tax.
- Enter the bill before tax.
- Set your tip percentage.
- Add the tax from your receipt to the total shown.
How to calculate tip percentage
Already left a tip and want to know what percentage it was? Use this formula:
Tip percentage = tip ÷ bill × 100
A $9 tip on a $45 bill is 9 ÷ 45 × 100 = 20%. The percentage calculator can do this for any two numbers.
The easy way to calculate a tip in your head: find 10% by moving the decimal point one place left, then build from there. On a $64 bill, 10% is $6.40, so 20% is $12.80 and 15% is $6.40 + $3.20 = $9.60.
Tip-out calculator for restaurant staff
In many US restaurants, servers share part of their tips with bussers, bartenders and food runners. This is called a tip-out. Restaurants usually set it in one of two ways:
- A share of sales — for example 2% of the server’s total food and drink sales.
- A share of tips — for example 20% of the tips the server took home.
Say a server sold $1,200 in a shift and earned $220 in tips. A 2% tip-out on sales is $24. A 20% tip-out on tips is $44. Use the percentage slider above with the sales or tip total as the “bill” to work out either one.

Frequently asked questions
It depends where you are. In the US and Canada, 15–20% is expected in restaurants and staff wages often assume it. In the UK, 10–15% is typical where no service charge applies. Much of Europe tips 5–10% or simply rounds up. In Japan, tipping is not customary and can cause offence. Check local convention rather than applying a single habit everywhere.
Either is defensible and the difference is small. Tipping on the pre-tax subtotal is arguably more logical, since tax is not part of the service you received. Tipping on the post-tax total is simpler because it is the figure at the bottom of the bill. On a £100 bill with 8% tax, 20% comes to £20 pre-tax or £21.60 post-tax.
It raises it, and by more than people expect when splitting between several people. On a £87.40 bill split four ways at 18%, rounding each share from £25.78 up to £26 adds £0.87 to the tip and lifts the effective rate to about 19%. With ten people rounding separately the effect is larger. The calculator shows the adjusted tip so you can see the result.
Then no further tip is expected. Many restaurants add service automatically — commonly 12.5% in the UK, or 18–20% for larger parties in the US. Check the bill before adding anything. If the charge is discretionary you can normally ask for it to be removed, and some people prefer to tip in cash instead so staff receive it directly.
In the US, 15% to 20% of the service price is normal for haircuts, colour, manicures and pedicures. On a $60 service that is $9 to $12. Tip more for great work or a tricky job.
Divide the tip by the bill and multiply by 100. A $9 tip on a $45 bill is 20%. To go the other way, multiply the bill by the percentage and divide by 100.
A 20% tip on $50 is $10, making the total $60. The quick way: 10% of $50 is $5, so double it. For 15% the tip is $7.50, and for 18% it is $9.
Divide the tip by the bill and multiply by 100. A $12 tip on a $60 bill is 12 divided by 60, times 100, which is 20%. Use the pre-tax bill if you want the standard etiquette figure.
