The Tip Formula Explained

If you find yourself without a phone and need to calculate a tip manually, the math is straightforward. Here is how you do it step-by-step:

Formula: Calculating the Tip Amount

  1. Convert the tip percentage into a decimal by dividing by 100. (e.g., 20% becomes 0.20)
  2. Multiply the total bill amount by this decimal.
Example: A $50 meal with a 20% tip.

Tip Amount: $50 × 0.20 = $10.00
Total Bill: $50 + $10 = $60.00

The 10% Mental Math Trick

You can easily calculate a 20% tip in your head without a calculator:

  1. Move the decimal point on your bill one place to the left. This gives you 10%.
  2. Double that number to get 20%.
Example: Your bill is $45.00.

10% = $4.50
20% = $4.50 × 2 = $9.00 Tip
