Bill Splitting
Dividing a shared check fairly and fast
Splitting a restaurant bill evenly is straightforward math — total plus tip, divided by the number of people — but it stops being simple the moment the group didn't order evenly. Someone had one drink, someone shared an appetizer, someone left early. That's where a basic even-split calculator and an item-level split diverge: even splitting is fast and fair when everyone ordered roughly the same; itemized splitting (assigning specific dishes to specific people) is fairer when they didn't, at the cost of more setup at the table.
Most bill-splitting situations are actually well served by the fast, even-split path — type the total, pick a tip, set the headcount, done. Tine is built around making that fast path as close to instant as possible, with the result updating live as you type, plus an item-level split for the times an even split genuinely isn't fair.

Frequently asked questions
What's the fastest way to split a bill fairly?
For a group that ordered roughly similar amounts, an even split — total plus tip divided by headcount — is both the fastest and fairest method. It only becomes unfair when order sizes vary significantly, at which point an itemized split (assigning specific items to specific people before dividing) better reflects what each person actually owes.
Should tip be calculated before or after splitting?
Mathematically it's equivalent either way — (bill + tip) ÷ people gives the same per-person total as splitting the bill first and adding each person's share of the tip separately — as long as the split is even. The two approaches only diverge once you're doing an itemized split, where tip is typically calculated on the full bill and then distributed proportionally or evenly across people.
Why do people round up bill splits instead of using the exact figure?
Exact division often produces an amount with odd cents that's awkward to pay in cash or that doesn't match a clean card charge. Rounding each person's share up to the nearest dollar (or other round unit) trades a small amount of mathematical precision for practical ease of actually settling up.
