A gratuity calculator figures out how much to tip and the total bill. Enter the bill amount and the tip percentage, and it calculates the tip, the total and each person’s share if you’re splitting. It’s handy at restaurants, salons, rideshares, food delivery and anywhere tipping is customary.
The formula is tip = bill × tip percentage. For a $64 bill with an 18 percent tip, the tip is $11.52, and the total is $75.52. A quick mental trick: 10 percent is the bill with the decimal moved one place ($6.40), so 20 percent is double that ($12.80), and 15 percent is 10 percent plus half of 10 percent ($6.40 + $3.20 = $9.60).
Common US tipping customs: about 15 to 20 percent at sit-down restaurants, often more for excellent service; a similar percentage for hair and beauty services; and a smaller amount or flat tip for counter service, coffee or takeout. Delivery drivers are often tipped a percentage or a few dollars, more for bad weather or long distances. Customs vary by country, and some restaurants add an automatic service charge for large groups, so check your bill.
Tips: decide whether to tip on the pre-tax or post-tax amount; many people tip on the pre-tax subtotal. When splitting, calculate the total with tip first and then divide. Remember that many service workers rely on tips for a large part of their income.
