Interpreting Results
Start with Tip Amount. Then compare Total Amount and Per Person Bill before deciding what changes the answer most.
Input Steps
Field by field
- 1
Bill Amount
Enter the bill amount, tip percent, number of people, and whether the split is even or custom. Use custom shares when alcohol, appetizers, or entrees were not shared equally.
- 2
Tip Percent
Read tip amount, total amount, and each person's share. In the U.S., about 15% is a lower casual baseline, 18%-20% is common for full-service dining, and service charges should not be tipped twice unless you mean to.
- 3
Number Of People
Rounding up is a convenience choice, not a budgeting principle, but it matters when several people are settling small transfers. Weighted splits avoid one diner subsidizing the table.
- 4
Split Mode
Send each person's exact share immediately and note whether gratuity was already included. If group dining is frequent, keep a standard tip-and-split rule so the decision is fast next time.
- 5
Custom Shares
Re-run whenever service charge, party size, or split method changes. Track only the final per-person amount, because that is the number people actually need to pay.
- 6
Round Up
Enter round up with realistic baseline assumptions before moving to sensitivity checks.
Run one base case and one sensitivity case before trusting a single output.
