Bill splitter & tip calculator
Split the check and work out the tip in seconds. Private — in your browser
Tips
Enter the pre-tip bill, pick a tip percentage (or drag the slider), and how many people are splitting it. “Round up” bumps each person's share up to the next whole dollar — handy for cash — so the group leaves a little extra. Everything is calculated locally; nothing is uploaded.
How to use the bill splitter
- Enter the bill amount — normally the pre-tip total from the check (cents welcome, e.g.
84.60). - Set the tip: tap a preset button (15 / 18 / 20 / 25%) or drag the slider anywhere from 0 to 40% in whole-percent steps.
- Enter the number of people splitting. It must be at least 1 — solo works fine if you only want the tip math.
- Read the three figures, updated live: tip amount, total (bill + tip), and per person. For an $84.60 check at 18% split four ways, that's a $15.23 tip and $24.96 each.
- Paying cash? Tick round up to whole dollars per person — each share bumps to the next dollar ($24.96 → $25.00) and the extra is counted toward the tip, so you can see what the group actually left.
Common uses
- Settle a restaurant check in seconds instead of passing a phone calculator around — everyone sees the same per-person figure.
- Split a group delivery or takeout order evenly, tip included, before anyone sends their share.
- Do quick tip math when dining alone: set people to 1 and use the presets to compare what 18% vs 20% actually costs.
- Handle a cash night out — the round-up option lands each share on a whole dollar so nobody's hunting for coins, and the overage becomes tip rather than vanishing.
- Divide a shared taxi, bar tab or hotel-breakfast bill where an even split is close enough.
Tips & limitations
- It splits evenly only — there's no itemizing who ordered the lobster. For uneven splits, run the tool once per person's subtotal, or accept the classic even-split compromise.
- The tip slider runs 0–40% in whole percents — no 12.5% or exact-dollar tips. For a precise amount, nudge the percentage until the tip figure matches.
- Pre-tax or post-tax tipping is custom, not math — the percentage applies to whatever bill figure you enter, so enter the subtotal you want to tip on.
- With round-up on, the numbers reconcile exactly: per-person × people = total, and the tip absorbs the rounding, showing the group's true effective tip.
- Nothing is saved between visits — reload and the bill is blank. Snap a photo if you need to remember who owed what.
How it's built & why it's safe
The math is three lines of arithmetic in your browser: tip = bill × percent / 100, total = bill + tip, per-person = total ÷ people. The round-up option applies Math.ceil to the per-person share, then recomputes the total and tip from there so all three figures stay consistent. Invalid people counts are caught (anything under 1 is corrected with a warning). It's a single small script — no server, no account, no storage: the bill amounts you type are never uploaded or remembered, and refreshing the page clears them completely.

Frequently asked questions
How is the tip calculated?
As a straight percentage of the bill amount you entered: the tip is bill x percent / 100, the total adds it on, and the per-person share divides that total by the head count. All three update live as you change any input.
What exactly does "round up to whole dollars per person" do?
It raises each person's share to the next whole dollar, then rebuilds the total from those rounded shares. The few extra cents per person are added to the displayed tip rather than lost, so the tip figure shows what the table actually leaves.
Should I enter the bill before or after tax?
That's etiquette, not arithmetic — many people tip on the pre-tax subtotal, others on the final total. Enter whichever number you want the percentage applied to and the tool does the rest.
Can it split the bill unevenly, by what each person ordered?
No — it divides the total equally. For an itemized split, total each person's items plus their share of anything shared, and run the calculator once per person.
Why does the tip stop at 40%?
The slider covers 0 to 40 in whole-percent steps, which spans normal tipping from counter service to exceptional service. Beyond that, add the extra to the bill yourself.
Does the page remember my bill or send it anywhere?
Neither. The calculation runs locally in your browser, nothing is written to storage, and no data leaves your device — reload the page and every field is back to its default.
