Calculating the appropriate tip percentage is essential when determining the amount to tip at a restaurant. While customary tip percentages differ by region or country, the following guidelines may assist in determining the appropriate tip percentage:

  1. Standard Tip Percentage: Generally, the standard tip percentage ranges between 15% and 20% of the total bill before tax. This is a good starting point for calculating the tip.
  2. Service Quality: The quality of service you received during your dining experience should be considered when tipping. If you received exceptional service, you may want to tip higher than the standard tip range or even go above it. However, tip is lower if the service is substandard.
  3. Adjustments for Special Situations: Generally, the tip percentage may be adjusted in certain circumstances, such as large parties or groups. Some restaurants automatically add a gratuity to the bill for larger groups. However, if it is not included, it may be advisable to increase the tip percentage to account for the additional effort and service provided.
  4. Local Customs: Research tipping customs in your particular region or country. Tipping practices may vary from area to area, so it is vital to be aware of the local norms to avoid overtipping.

In general, tipping is a way of showing appreciation for a service provided, so when determining how much to tip, it is essential to consider the abovementioned factors.

Calculate the pre-tax tip.

To calculate a pre-tax tip, you must determine the amount based on the total bill before applying taxes. Here is a simple guide to assist you:

  1. Obtain the Total Bill Amount: The amount to be included in the pre-tax tip will be determined based on the total bill amount shown on your restaurant receipt.
  2. Determine the Tip Percentage: Select the tip percentage you wish to use. The tip percentage is usually a percentage of the pre-tax total bill amount. Typical tip percentages range between 15% and 20%.
  3. Convert the Tip Percentage to Decimal Form: You should convert the tip percentage to decimal form to make calculations easier. For example, if you choose a 15% tip, you should convert it to 0.15.
  4. Calculate the Pre-Tax Tip: You can calculate the pre-tax tip amount by multiplying the pre-tax total bill amount by the tip percentage in decimal form. 

For example: if the pre-tax total bill is $50 and a 15% tip is left, multiply $50 by 0.15 to get a $7.50 pre-tax tip.

The pre-tax tip ensures that the tip is based on the amount you were initially charged before taxes were added. It is essential to remember that local customs and individual preferences may differ, so adjust your tip percentage accordingly to reflect your personal preferences and the level of service you received.

Adjust for exceptional circumstances.

The tip amount may need to be adjusted in certain exceptional circumstances. Here are a few examples of situations in which you might consider adjusting the tip amount:

  1. Large Parties or Group Dining: It is common for restaurants to add an automatic gratuity to the bill when dining with a large group. However, if the gratuity is not included, the tip percentage should be increased to account for the additional effort in serving a larger group.
  2. Extraordinary Service: When the service the restaurant staff provides exceeds your expectations, you may consider increasing the tip amount as a token of appreciation. You can do this by increasing the tip percentage or adding a discretionary amount.
  3. Discounts, Promotions, or Gift Cards: If you are using a discount coupon, participating in a promotional offer, or paying with a gift card, it is crucial to calculate the tip based on the original price of the items before any discounts are applied. The tip should reflect the total value of the service provided in this manner.

It is important to remember that adjusting the tip in exceptional circumstances is a personal choice based on your assessment of the situation and the level of service. Being fair and considerate when determining the final tip amount is essential.

Splitting the tip

When you dine with others, it is essential to determine how the tip will be split relatively among all parties involved. Below are some approaches you may wish to consider:

  1. Equal Split: There is a standard method for dividing the total tip amount equally among the members of the dining party, which can be effective when everyone consumes a similar amount or when the service received is consistent.
  2. Individual Orders: Alternatively, if each person in the group has a separate check or has ordered items at different prices, it is possible to calculate the tip based on individual orders. The individual would then be responsible for tipping according to their bill.
  3. Proportional Contributions: It may be appropriate to split the tip proportionally when one or more individuals have made significant contributions or ordered more expensive items; in this case, each individual’s tip would be calculated on their expenditures.
  4. Agreement addition: To avoid any misunderstanding or disagreement, discussing and agreeing on splitting the tip with your dining companions before calculating and paying is crucial. This ensures that everyone is on the same page and that any misunderstandings or conflicts can be avoided.

Choose the best method for your situation and ensure everyone is comfortable. The goal is to find a fair and agreeable method for splitting the tip.

How to Calculate Restaurant Tips | Final considerations

Here are a few considerations to keep in mind as you complete the process of calculating the restaurant tip:

  1. Rounding Up: Tipping is customarily rounded up to the nearest whole number or to a more generous amount to demonstrate goodwill and acknowledge the service provided.
  2. Leaving Feedback: Whether you experienced exceptional service or encountered problems during your dining experience, consider leaving feedback or reviews. Positive feedback can encourage the staff, while constructive criticism can help the restaurant improve its service in the future.
  3. Local Customs: Consider the tipping customs in your region or country. Different places may have different expectations. Make sure you understand the local norms to ensure you are following them correctly.
  4. Gratitude: The purpose of tipping is to express gratitude for the service provided. It is also a way to acknowledge the hard work of the restaurant staff. When interacting with the staff, remember to be respectful and appreciative.

When you consider these five final points, you can guarantee that your tip will be thoughtful, respectful, and representative of the quality of service you have received.


What is the formula for tipping restaurants?

If you wish to leave a tip, you can multiply your total check by one plus the decimal percentage of the tip you wish to leave. For example, if you want to leave a 20% tip, add 1 to 0.20, resulting in 1.20. To determine the amount you will leave, including the tip, multiply the bill by 1.20.

How do you tip 20% at a restaurant?

At Eater NY, Ryan Sutton, chief critic, recommends tipping a minimum of 20 percent before tax. However, he recommends tipping 20 percent after-tax rather than before tax-for exceptional service. In addition, it is recommended that you consider the full price of a complimentary drink or item when calculating the tip if a restaurant offers you a complimentary drink or item.

How do you calculate cash tips?

The tip amount is generally calculated by multiplying the cost of the service by 0. XX, where XX represents the percentage you intend to leave as a tip. The total service cost, including the service and tip, can be calculated by multiplying the cost by 1.

What is the right amount of tips?

When determining the appropriate tip amount at a restaurant, Robin DiPietro, Ph.D., professor and program director at the College of Hospitality, Retail, and Sport Management at the University of South Carolina, recommends tipping between 15 percent (for average service) and 20 percent (for excellent service).

What are the new rules for tipping?

Dr. Peters explains that sometimes, 20% is not the revised minimum tip. If you receive exceptional or exceptionally prompt service, you may add a few additional dollars to show your appreciation. Some people recommend a 10% tip, while others consider $1 or $2 a reasonable tip for good service.


In conclusion, knowing how to calculate the restaurant tip is an important skill that ensures you leave an appropriate gratuity for the service received. You can be confident in tipping by considering several factors, such as the tip percentage, adjusting for exceptional circumstances, splitting the tip, and rounding up. Be mindful of local customs and communicate openly with your dining companions when dividing tips. By tipping, you express your gratitude and support to the hardworking restaurant staff.
