What is a Tip?
A tip (gratuity) is a voluntary payment made to service workers in addition to the bill. In the US, tipping is customary at restaurants, bars, salons, and for delivery services. Tips often make up a significant portion of service workers' income, as base wages are typically below minimum wage.
Tip Calculation Formula
Tip Amount = Bill Amount * Tip Percentage. Total = Bill Amount + Tip Amount. Per Person = Total / Number of People. For example, a $60 bill with 20% tip: Tip = $60 * 0.20 = $12. Total = $72. Split among 4 people: $18 each.
Standard Tip Percentages
- •Restaurants: 15% (adequate), 18% (good), 20%+ (excellent). Bars: $1-2 per drink or 15-20% of tab. Delivery: 10-15% ($2-5 minimum). Hair salons: 15-20%. Hotel housekeeping: $2-5/night. Valet: $2-5. These are guidelines—adjust based on service quality and local customs.
How to Split a Bill with Tip
Calculate the tip on the total pre-tax bill. Add tip to the total. Divide by the number of people. Example: $120 bill, 20% tip = $24 tip. Total = $144. Split among 6 people = $24 each. If people ordered different amounts, calculate individual shares proportionally.
Tipping Mistakes to Avoid
Tipping on the post-tax amount (tip on pre-tax only). Not tipping for poor service instead of addressing it with management (10% minimum is standard). Forgetting to tip for takeout (10% is appreciated). Not adjusting for large groups (many restaurants auto-add 18-20% for parties of 6+).
