Restaurant Dinner for 4 — Splitting the Bill Evenly
You have just had dinner with three friends at a restaurant. The bill arrives and it is time to split it four ways, including the tip. This scenario walks through the entire process step by step, so everyone pays their fair share without any awkward maths at the table.
The Scenario
Four colleagues — Sam, Jordan, Alex, and Morgan — go to dinner at a mid-range Italian restaurant in New York. The food bill comes to $142.00 before tax. New York City sales tax is 8.875%, and the group wants to leave an 18% tip on the pre-tax amount.
Step 1: Calculate Tax
Tax: $142.00 × 0.08875 = $12.60 (rounded). Bill with tax: $142.00 + $12.60 = $154.60.
Step 2: Calculate Tip (Pre-Tax)
The group decides to tip on the pre-tax amount of $142.00. Tip: $142.00 × 0.18 = $25.56.
Step 3: Calculate Total
Total: $154.60 (bill with tax) + $25.56 (tip) = $180.16.
Step 4: Split Four Ways
Per person: $180.16 ÷ 4 = $45.04.

Key Takeaways
- Tipping on the pre-tax amount is common in the US and saves a few dollars for the group.
- Splitting evenly is the simplest approach — no one needs to track who ordered what.
- If one person had significantly more expensive items, consider splitting proportionally instead.
- Using a calculator prevents errors and speeds up the process.
Frequently Asked Questions
What if someone orders only drinks?
If one person's order is much cheaper, it may be fairer to split by amount ordered rather than evenly. Our calculator's standard mode can help each person calculate their individual share.
Should the person who pays the full bill get reimbursed differently?
If one person puts the entire bill on their card, each other person should Venmo or transfer their share ($45.04 in this case). The card-payer gets the card rewards as a small perk.
