Tip Calculator
A tip calculator turns a fast dinner-table decision into an exact number instead of a guess. Enter the bill amount and a tip percentage, and this tip calculator returns the tip amount and the total bill right away, so you know what to add before the server brings the check back. Switch to Split Bill + Tip mode when the check is shared, and the calculator divides that same total, tip included, evenly across everyone at the table. Use Tip Only mode for a solo bill, a coffee run, or any time you just need the tip amount and the new total. Use Split Bill + Tip mode for group dinners, a shared cab fare with a driver tip, or any bill where several people are covering one check and want an even split of both the bill and the gratuity. The tool works the same way for restaurants, bars, delivery orders, salons, and any other service where a percentage-based tip applies.
Quick answer
The tip amount is based on the bill total you entered, before adding the tip.
Calculate the tip and final bill total.

What this tells you
- •The tip amount is based on the bill total you entered, before adding the tip.
- •Total bill includes both your original bill and the calculated tip.
- •In split mode, each person's share includes their portion of both the bill and the tip.
- •This estimate assumes your entered bill amount is the base used for tip calculation.
- •Tip percentage is treated as a flat rate applied once. It does not compound or change based on party size.
- •Split Between accepts any whole number of people from 1 up to 100, which covers everything from a two-person dinner to a large group reservation.
- •If you leave the tip percentage blank, the calculator treats it as 0% and only totals the bill amount you entered.
How to Use
- 1Enter the bill amount shown on your receipt or check, using dollars and cents, for example 84.50.
- 2Add the tip percentage you want to leave. The field starts at 18%, a common default, but you can change it to any value from 0 to 100.
- 3Choose mode: Tip Only for tip + total, or Split Bill + Tip to divide the full total, tip included, across a group.
- 4If you select Split Bill + Tip, enter how many people are sharing the bill.
- 5Review the results shown below the form: tip amount, total bill, total per person, tip per person, and the original bill before tip.
- 6Adjust any input and the results update immediately, so you can compare a few tip percentages before deciding what to leave.
How It Works
Formula
Tip Amount = Bill Amount × (Tip % ÷ 100)
Total Bill = Bill Amount + Tip Amount
Total Per Person = Total Bill ÷ Number of People
Tip Per Person = Tip Amount ÷ Number of PeopleThe calculator multiplies your bill amount by the tip percentage, expressed as a decimal, to get the tip amount. It then adds that tip to the original bill to get the total bill. Both numbers stay the same whether you are in Tip Only or Split Bill + Tip mode. In Split Bill + Tip mode, the calculator divides the total bill, which already includes the tip, by the number of people entered in Split Between. That gives Total Per Person, the full amount each person owes. It also divides the tip amount alone by the same number of people to show Tip Per Person, which is useful when one person is covering the bill and everyone else just needs to pay back their share of the gratuity. The formula assumes an even split. It does not adjust for people who ordered more expensive items, shared appetizers unevenly, or skipped alcohol, and it does not separate tax from the bill amount. If your receipt lists tax as a separate line, decide whether you want to tip on the subtotal or the post-tax total, then enter that figure as the bill amount.

Worked Examples
Example 1: Solo dinner, tip only
Tip amount = $48.00 × 0.15 = $7.20. Total bill = $48.00 + $7.20 = $55.20. Use Tip Only mode like this when one person is paying and you just need the tip amount and the final number to hand over.
Example 2: Group dinner, split four ways
Tip amount = $96.00 × 0.18 = $17.28. Total bill = $96.00 + $17.28 = $113.28. Split four ways, total per person = $113.28 ÷ 4 = $28.32, and tip per person = $17.28 ÷ 4 = $4.32. This mode is useful when a group wants to split the whole restaurant bill fairly.
Example 3: Large group at a shared table
Tip amount = $310.40 × 0.22 = $68.29. Total bill = $310.40 + $68.29 = $378.69. Split seven ways, total per person = $378.69 ÷ 7 = $54.10, and each person's share of the tip is $68.29 ÷ 7 = $9.76. This is a common setup for a birthday dinner or a team meal where the group agrees to split evenly regardless of what everyone ordered.
Example 4: Coffee run, tip only
Tip amount = $22.50 × 0.10 = $2.25. Total bill = $22.50 + $2.25 = $24.75. Counter-service orders like coffee or takeout often use a lower tip percentage than a full sit-down meal, and Tip Only mode gives the exact total without needing a split.
Example 5: Celebration dinner, split three ways
Tip amount = $150.00 × 0.25 = $37.50. Total bill = $150.00 + $37.50 = $187.50. Split three ways, total per person = $187.50 ÷ 3 = $62.50, and tip per person = $37.50 ÷ 3 = $12.50. A 25% tip like this is typical when a group wants to reward standout service on a special occasion.
Common Tip Percentages by Bill Amount
How standard tip percentages translate into dollar amounts on a few typical bill sizes.
| Bill amount | 15% tip | 18% tip | 20% tip | 25% tip |
|---|---|---|---|---|
| $20.00 | $3.00 | $3.60 | $4.00 | $5.00 |
| $50.00 | $7.50 | $9.00 | $10.00 | $12.50 |
| $100.00 | $15.00 | $18.00 | $20.00 | $25.00 |
These figures show the tip amount only, not the total bill. Add the tip to the bill amount to get the full amount you will pay.
How much should you tip?
Standard sit-down restaurant tips in the United States usually run between 15% and 20% of the bill for typical service. Many diners use 20% as a default and move toward 25% for standout service or down toward 15% when service was slow or incomplete. These are customs, not fixed rules, and they vary by region, restaurant type, and personal budget.
Whether to tip on the pre-tax subtotal or the post-tax total comes down to personal preference. Tipping on the pre-tax subtotal is the more traditional guidance, but many people find it simpler to tip a round percentage of whatever total is printed at the bottom of the receipt. This calculator uses whichever bill amount you enter, so that choice is yours to make before you type in a number.
Large parties often already have gratuity built into the bill. Many restaurants automatically add an 18% to 20% service charge for groups above a set size, commonly six or eight guests. Check the bottom of the receipt for a line labeled service charge or gratuity before adding another tip on top, since tipping twice on the same service is a common and avoidable mistake.
Tipping expectations also shift by service type. Delivery drivers, bartenders, hairdressers, and taxi or rideshare drivers each tend to follow their own typical ranges, and many people apply a lower percentage for counter service or takeout than for a full sit-down meal. Use this calculator any time you need to turn a chosen percentage into an exact dollar figure, regardless of which service you are tipping for.
Common mistakes
- Entering the tip percentage as a whole money amount instead of a percent
- Forgetting to switch between Tip Only and Split Bill + Tip
- Assuming the split is for the tip only instead of the full bill including tip
- Using the wrong number of people when splitting the bill, especially forgetting a guest who left early or a child who does not need a full share
- Mixing up the total bill with the per person result when reading the numbers back to the table
- Adding a tip on top of a bill that already includes an automatic gratuity or service charge for a large party
