Pro Tip

Always calculate tip on the pre-tax subtotal, not the total including tax. Most receipt-suggested tip amounts are based on the post-tax total — you can save 5-8% by calculating on the subtotal instead. For large groups (6+), many restaurants add 18-20% gratuity automatically — check your bill before adding more.
