About this tool
Why use this tool
Splitting a check with friends, roommates or coworkers is a routine but often confusing task in the US, especially when factoring in tax (varies 4-10% by state) and a 15-25% tip on top. This calculator instantly divides the total among any number of people. It's essential for group dinners, road trips, bachelor/bachelorette parties, roommate expenses, and office lunches. According to a 2024 Bank of America survey, 76% of Americans split expenses digitally at least monthly.
How it works
Per-person share = (Bill + Tip) / Number of people. The tip is calculated as a percentage of the pre-tax subtotal (standard US practice), then added to the total before dividing. Apps like Venmo, Zelle, Cash App and Splitwise have made splitting seamless — no more IOUs. Zelle transfers are instant and free between major US banks; Venmo charges 1.75% for instant transfers to your bank.
Real example
Dinner for 6 at a Brooklyn restaurant: subtotal $186, NYC sales tax 8.875% ($16.50), 20% tip on pre-tax ($37.20). Grand total: $239.70. Per person: $39.95. For a weekend Airbnb in Nashville for 4 people ($480 rental + $220 groceries + $95 gas): $198.75 each. For a $360 group gift for a colleague's retirement, split 15 ways: $24 per person.
Practical tips
Decide upfront how you'll split: evenly, or itemized (each person pays for what they ordered — helpful if some skip alcohol or dessert). Restaurants in many states will now split the check onto multiple cards automatically (up to 4-6 cards typically). Use Splitwise for multi-day trips with shared expenses. Under IRS rules, informal reimbursements between friends via Venmo or Zelle are NOT taxable income — but if you receive $5,000+ in business payments via a third-party app in 2026, the platform issues Form 1099-K to the IRS.
Disclaimer
This tool performs an equal split. It doesn't account for individual preferences (vegetarians, non-drinkers, allergies). For itemized splits down to the penny, use Splitwise or Tab. State-specific sales tax and tip norms may apply. This is not tax advice — consult a CPA for questions about IRS reporting thresholds on peer-to-peer payment apps (revised under the American Rescue Plan Act, with delayed enforcement through 2026).
