Tip, total, and per-person split — all three numbers, instantly.
In the US, 15–20% is the standard range for table service (18% is the common middle), 20%+ for excellent service, and a dollar or two per drink at a bar. The calculator applies the percentage to the bill you enter — use the pre-tax subtotal if you want to tip strictly on the meal.
Do you tip on the tax? Custom says tip on the pre-tax amount, though many people tip on the total for simplicity. The difference on most bills is small.
How do I split unevenly? This tool splits evenly. For uneven splits, calculate each person’s share of the subtotal and tip on that share at the same percentage.
