How Do You Calculate a 20 Percent Tip?
Multiply the bill by 0.20, or find 10% by moving the decimal point one place left and double it. On a $50 bill, 10% is $5, so a 20 percent tip on $50 is $10 and the total is $60. On $85 the tip is $17.
| Bill | 15% tip | 18% tip | 20% tip |
|---|---|---|---|
| $20 | $3.00 | $3.60 | $4.00 |
| $30 | $4.50 | $5.40 | $6.00 |
| $50 | $7.50 | $9.00 | $10.00 |
| $60 | $9.00 | $10.80 | $12.00 |
| $85 | $12.75 | $15.30 | $17.00 |
| $100 | $15.00 | $18.00 | $20.00 |
How the Calculator Works
It multiplies the bill by the tip rate, adds the tip for the total, then divides by the number of people.
Formula: Tip = Bill × (Tip % ÷ 100); Total = Bill + Tip; Per-Person Total = Total ÷ People
- Bill: the bill amount before tip
- Tip %: the tip percentage, chosen from the 15/18/20/25% presets or entered as a custom value
- People: the number of people splitting the bill, defaulting to 1
Example Scenarios
| Bill Amount | Tip % | People | Tip Amount | Total | Per Person |
|---|---|---|---|---|---|
| $18.00 | 20% | 1 | $3.60 | $21.60 | $21.60 |
| $32.50 | 15% | 2 | $4.88 | $37.38 | $18.69 |
| $50.00 | 20% | 1 | $10.00 | $60.00 | $60.00 |
| $85.00 | 18% | 4 | $15.30 | $100.30 | $25.08 |
| $120.00 | 25% | 6 | $30.00 | $150.00 | $25.00 |
How to Calculate Tip in Your Head
Start from 10% and build up. Here is how much tip for an $85 bill at each common rate:
- Find 10% by moving the decimal: $85 becomes $8.50.
- Double it for 20%: $17.
- For 15%, add half of the 10%: $8.50 + $4.25 = $12.75.
- For 18%, take the 20% and subtract 2% ($1.70): $17 − $1.70 = $15.30.
Should You Tip on Pre or Post Tax?
Pre-tax is the traditional basis, though the difference is small. On an $80 meal with 8% tax, 20% of the pre-tax bill is $16, and 20% of the $86.40 total is $17.28. Enter whichever amount you want the tip based on.
- Check the bill for a service charge first. Many restaurants add one automatically for large groups, and tipping on top of it means paying twice.
- With coupons or discounts, many people tip on the original price, since the server did the same work.
Customs vary by country: tipping is uncommon in Japan, and in much of Europe people round up or leave a little. The gratuity article on Wikipedia summarises norms around the world.
When splitting, the total is divided evenly. If one person ordered much more, work out their share separately, then run the rest of the group through the tool.
