Tip & Total
💡 Expert Tip
Tip on PRE-tax amount, not total—saves 8-10% on every tip. $50 food + $4.50 tax = $54.50 total. 20% on $54.50 = $10.90. 20% on $50 pre-tax = $10. Difference: $0.90 per meal × 100 meals/year = $90/year saved without undertipping. I tipped on total for years before server friend explained standard is pre-tax. Now calculate: bill - tax = tip amount. Or use split check if available (usually shows pre-tax subtotal).
