How is Bill Split Calculated? (Formula Explained)

The calculator uses the following formulas to determine each person's share:

Total with Tip & Tax = Bill Amount + (Bill Amount × Tip %) + (Bill Amount × Tax %)

Per Person Share = Total with Tip & Tax / Number of People

Bill Amount: The original total before tip and tax.
Tip %: The percentage of the bill added as a tip (e.g., 15%).
Tax %: The percentage of the bill added as tax.
Number of People: How many people are splitting the bill.
Custom Split: Optionally assign specific amounts to each person (must sum to the total).

Example: Bill Split Calculation Step-by-Step

Let's say four friends have a restaurant bill of $120. They want to leave a 20% tip and the tax is 8%.

Bill Amount: $120
Tip: 20% of $120 = $24
Tax: 8% of $120 = $9.60
Total with Tip & Tax: $120 + $24 + $9.60 = $153.60
Number of People: 4
Per Person Share: $153.60 / 4 = $38.40

Each friend pays $38.40. If using custom split, you can assign different amounts for each person based on what they ordered.
