How This Tool Works
Input Base Bill — Enter the total cost of the meal, utility, or expense before any tips or additional taxes.
Choose Tip & Tax Formats — Use the toggle buttons to apply tips and taxes as either a percentage (%) or a flat dollar amount ($).
Calculate Grand Total — The engine adds the tip and tax to your base amount to figure out the exact final charge.
Split It Up — The grand total is divided evenly by the number of people you entered, down to the exact penny.
The Math & Etiquette Behind the Tool
Tip Amount = Base Bill × (Tip % / 100)
Per Person Cost = (Base Bill + Tip Amount + Tax Amount) / Number of People
Real-World Examples
4 Friends at a Restaurant
Base Bill: $150.00
Tip (20%): $30.00
Tax (8%): $12.00
The total comes to $192.00. Divided by 4 people, everyone needs to Venmo exactly $48.00.
Splitting Monthly Utilities
Base Bill: $240.00
Tip / Tax: $0.00
People: 3 Roommates
Because this is a fixed utility bill, there is no tip or tax. The calculator simply divides the $240 by 3, making each roommate's share exactly $80.00.
