About the tip calculator
This calculator takes the guesswork out of tipping at a restaurant, salon, or anywhere else a gratuity is customary. Enter your bill amount and a tip percentage, and it instantly shows the tip amount, the total you'll pay, and — if you're splitting the check — how much each person owes. It's the same math servers and diners have always done on a napkin, just faster and less error-prone.
The calculation itself has two steps. First, the tip amount is your bill multiplied by the tip percentage — a $50 bill at 18% comes to a $9 tip. Second, the total bill is simply the original bill plus that tip. If you're splitting the check between multiple people, the calculator divides the total (bill plus tip) evenly across however many people you specify, so everyone pays the same fair share.
In the United States, 15–20% is the most common tipping range at full-service restaurants, with 18–20% increasingly treated as the default for good service and 20%+ reserved for exceptional service. Some diners tip on the pre-tax subtotal, others on the post-tax total — the difference is usually small, but if you want to be precise, enter the pre-tax amount as your bill for a more conservative tip. Tipping norms vary considerably outside the US, where service charges are often included or tipping is far less customary, so it's worth checking local expectations when traveling.
Splitting a bill evenly is the simplest approach when everyone ordered roughly the same amount, but it isn't always the fairest — someone who ordered a salad and water might end up subsidizing a table-mate's steak and cocktails. For groups where orders vary a lot, consider having each person calculate their own item total plus a proportional tip, or use this calculator per-person after dividing up the itemized costs manually.
This tool is meant for quick, everyday math — splitting a dinner bill, checking a delivery tip, or double-checking a total before you sign a receipt. It doesn't know about service charges already included in your bill, so check your receipt for a line like "gratuity included" before adding another tip on top.

Tip calculator questions
How tipping and bill splitting work.
How do I calculate a tip?
Multiply your bill amount by the tip percentage (as a decimal) to get the tip amount. For example, a $50 bill at 18% comes to a $9 tip, for a $59 total.
What is a good tip percentage?
In the US, 15–20% is standard at full-service restaurants, with 18–20% common for good service and 20% or more for exceptional service. Bars, delivery, and salons often use similar ranges, though norms vary by service type and location.
How do I split a bill between multiple people?
Enter the total bill and tip percentage, then set the number of people. The calculator divides the total (bill plus tip) evenly across everyone, so each person pays the same amount.
Should I tip on the pre-tax or post-tax amount?
Either is common. Tipping on the pre-tax subtotal is slightly more conservative, while tipping on the post-tax total is simpler and common in practice. The difference is usually just a dollar or two on typical restaurant bills.
Is tipping mandatory?
In the US, tipping isn't legally required but is a strong social expectation for many services, since tipped workers are often paid a lower base wage. In many other countries, service charges are included or tipping is far less customary — check local norms when traveling.
What if the service was bad, or exceptional?
Many people adjust their tip percentage up or down based on service quality — for example, tipping 10–15% for poor service or 25%+ for outstanding service. This calculator lets you enter any percentage you choose.
Do I need to tip on takeout or delivery orders?
Norms vary — delivery drivers are commonly tipped 10–20% or a flat amount, while tipping on simple takeout pickup is more optional and often smaller. Check for a prompted tip screen, which often suggests typical ranges for that type of order.
Does this calculator account for service charges already on my bill?
No — check your receipt first. If a gratuity or service charge is already included (common for large groups), you generally don't need to add another tip on top unless you want to for exceptional service.
