Every tip percentage on a $75 bill
| Tip % | Tip Amount | Total Bill |
|---|---|---|
| 15% | $11.25 | $86.25 |
| 18% | $13.50 | $88.50 |
| 20% | $15.00 | $90.00 |
| 22% | $16.50 | $91.50 |
| 25% | $18.75 | $93.75 |
| 30% | $22.50 | $97.50 |
The spread from 15% to 25% on a $75 bill is $7.50 — the difference between $11.25 and $18.75. On a single meal, that range is unlikely to affect your budget either way. Choose the percentage that matches the service you received and the standard you want to maintain.
When 18% is the right call
The tipping landscape has shifted over the past decade. 15% used to be standard; now many etiquette guides and surveys indicate 20% has become the new baseline for good service. Where does 18% fit?
18% is perfectly appropriate for: Standard, competent service that met your expectations without anything exceptional. Your server took your order, brought your food in a reasonable time, refilled drinks when asked, and handled the check efficiently. That's the 18% tier — service that was professional and adequate.
Consider 20-25% when: Your server was attentive, friendly, remembered details, handled a complicated order well, or provided a particularly enjoyable experience. For large groups (which require more coordination), 20%+ is appropriate regardless of service quality.
Quick mental math for 18% on any bill
🧮 Two methods to calculate 18% in your head
Method 1 is faster for most people: calculate 20% (just move the decimal and double), then subtract a small amount. Method 2 is more precise if you're comfortable with mental multiplication. Either way, you don't need a calculator for 18% — it's a quick adjustment from the easy 10% or 20% calculation.
