How to Use the Restaurant Bill Splitter
Enter the pre-tip total, number of diners, tip percentage, and any shared extras (like a delivery fee) to instantly calculate tip amount, grand total, and exact per-person cost — with a rounded-up option for easy cash handling.
Standard US tipping is 18–20% for sit-down restaurant service. Tip is calculated on the pre-tax subtotal in most cases, though tipping on the post-tax total is also widely accepted. The default tip here is set at 18% — adjust to your preference.
The rounded-up result uses $0.25 increments to make cash payment easier. For Venmo or Zelle, the exact amount is more appropriate.
Frequently Asked Questions
15% is the minimum for adequate service in the US; 18–20% is standard; 22–25% is for excellent service. For delivery, 10–15% is typical. Counter service and takeout: 10–15% is optional but appreciated.
For an equal split, use this calculator with the full total. For an unequal split, calculate each person's share separately: their food cost × (1 + tip/100). Then add shared items (appetizers, wine) divided by the party size.
In the US it's generally acceptable to request separate checks at the start of the meal, before ordering. Asking to split after the bill arrives is more awkward and may not be possible at busy restaurants. Ask your server early.
