How to use this calculator
- Enter the bill amount EXACTLY as it appears on the receipt (subtotal line for US standard).
- Enter the tip line from the receipt (or compute it as total − subtotal).
- If your receipt shows tax-inclusive subtotal, switch the "How is bill measured" dropdown to match.
- Compare your % to the 15 / 18 / 20% reference lines below — the calculator shows whether you were over or under each band.
About this calculator
Restaurant-receipt analysis: you already paid the tip, you want to know what percentage that worked out to. Standard US tipping benchmarks are baked in for comparison (15 / 18 / 20 / 22 / 25%). Pick the right "base" mode: most US servers tip on the pre-tax subtotal, but if your receipt shows tax-inclusive subtotal (some POS systems) or you entered a total that already includes the tip, switch modes. The result includes the implied percent to 2 decimals plus an etiquette-band label calibrated to the US Emily-Post-Institute convention (15-20% for sit-down service).
Frequently asked
US Emily-Post-Institute etiquette guidance: tip on pre-tax subtotal — that's what the service is for. Some servers prefer the post-tax total (it's ~6-10% more depending on state tax). Both are defensible; the calculator handles either via the mode dropdown.
