Tip Breakdown
Should you tip on pre-tax or post-tax?
Pre-tax tip = Subtotal × Tip %
Post-tax tip = (Subtotal + Tax) × Tip %
The difference matters more than you think:
| Subtotal | Tax (8%) | 20% Pre-Tax Tip | 20% Post-Tax Tip | Difference |
|---|---|---|---|---|
| $50 | $4.00 | $10.00 | $10.80 | $0.80 |
| $100 | $8.00 | $20.00 | $21.60 | $1.60 |
| $200 | $16.00 | $40.00 | $43.20 | $3.20 |
Etiquette:
- Pre-tax is technically correct (you tip on food/service, not government tax)
- Post-tax is simpler and slightly more generous
- Many servers prefer post-tax
- Either way, 15–20% is the standard range
