How to Calculate a Tip

The formula for calculating a tip is straightforward:

Tip = Bill Amount × (Tip Percentage / 100)

For example, a 20% tip on an $85 bill: $85 × 0.20 = $17.00, making the total $102.00.

Quick Mental Math Tricks

  • 10% tip: Move the decimal one place left. $85 → $8.50
  • 15% tip: Calculate 10%, then add half. $8.50 + $4.25 = $12.75
  • 20% tip: Calculate 10%, then double. $8.50 × 2 = $17.00
  • 25% tip: Calculate 10%, multiply by 2.5. Or find 25% by dividing by 4.
