Tip is conventionally computed on the pre-tax subtotal while tax applies to the subtotal: $85 at 18% tip ($15.30) plus 8.5% tax ($7.23) totals $107.53. Some diners tip on the post-tax total — the difference here is $1.30, small per meal but systematic across a year of dining.
US tipping norms by venue: 18–20% full-service pre-tax, 15% adequate, 20%+ excellent; bars $1–2 per drink; delivery 15–20% with minimums; fast-casual tip screens are optional (10%+ is generosity, not obligation); hotels, valets and guides carry their own $2–5 conventions. Europe typically includes service — rounding up suffices except tourist zones.
Tax mechanics vary by locality: US sales tax 0–10%+ added at register (this calculator's model), VAT-inclusive pricing in Europe and much of Asia (no math needed), Canadian GST/PST/HST split by province, and delivery/platform fees that may or may not be taxable depending on jurisdiction. Enter the rate actually printed on local receipts.
Splitting fairly: even splits divide the total, itemized splits assign dishes plus proportional tax and tip. Mixed groups (drinkers vs non-drinkers, appetizers shared unevenly) deserve itemization — apps that split evenly overcharge the light orderers every time. Large parties often face 18–20% auto-gratuity; check before double-tipping.
Business and tax angles: business meals deduct 50% for self-employed (with documentation: who, where, business purpose), employer per-diems cap differently, and tip income is taxable to staff — no bearing on your math, but context for why service charges (mandatory, house-kept) differ legally from tips (voluntary, staff-kept).
Tipping creep is real: tablet prompts at 25–30% for counter service reset anchors upward yearly. A personal policy (e.g. 20% full-service, 10% counter, $0 coerced fast-food screens) beats in-the-moment guilt math — decide once, apply always.
Calculate total bill with tip and tax: enter subtotal, tip percent and tax rate to see tip, tax, total and per person. Formula: Tip = subtotal*tipPct. Example: With $85 subtotal, 18% tip $15.30, 8.5% tax $7.23: total $107.53, three people $35.84 each.
