Split one bill the way Splitwise would — equally, by percentage, by exact amounts, or weighted by income and nights stayed — without an app, an account, or a group invite.
Every figure is worked out in whole cents, so the parts always add back up to the total. This is a calculator, not a ledger: it is built for the split you need right now.
Each person pays
Enter a total amount and how many people are splitting it.
Deciding between the two apps rather than splitting a bill?
Compare SuperDivide and SplitwiseThe result appears as you type. Nothing is submitted anywhere.
Type the bill, the rent, or the invoice into the total field. A dollar sign and thousands separators are both fine — "1,204.50" and "$1204.5" parse the same way.
Equal, by percentage, by exact amounts, or by share. The four options line up with the ones you would reach for inside a Splitwise expense.
An equal split only needs a headcount. The other three give you a row per person: a percentage, a dollar figure, or a share weight such as income or nights stayed.
The breakdown updates as you type, with each person shown as both a share of the total and a figure. The arithmetic runs in the page itself, so there is no submit step and no result to wait for.
If you already think in groups, balances, and shares, this is the whole map — and the two places where a calculator honestly cannot follow.
In Splitwise
Group
One calculation, no container
A Splitwise group holds many expenses and the balances between people. There is no equivalent here on purpose: you fill in one expense, read the answer, and close the tab. Nobody gets invited and nobody needs an account — not even you.
In Splitwise
Split equally
Equal split
Enter the total and a headcount, up to 100 people. On a total that will not divide cleanly, the leftover pennies are handed out one at a time rather than rounded away, so the parts add back up to the total exactly.
In Splitwise
Split by percentages
By percentage
A row per person, each with a percentage, and they have to reach 100. The running total sits under the list, because a column of numbers that should add to 100 but adds to 97 is a mistake you can only catch in aggregate.
In Splitwise
Split by exact amounts
Exact amounts
Type what each person owes. If the amounts fall short of the total, the gap is shown as unassigned; if they overshoot, that is shown too. Nothing is silently rescaled to force the numbers to agree — you are the one who knows which figure is wrong.
In Splitwise
Split by shares or adjustments
By share
Weight the split by any number: monthly income for rent, nights stayed for a rental, square footage for whoever took the big bedroom. Enter the weights and the arithmetic follows them.
In Splitwise
Balances
The "who pays what" list
The list under the result carries the same information a group balance screen does, for this one expense: each name, their share of the total as a percentage, and the amount they owe.
In Splitwise
Simplify debts and settle up
Not here, deliberately
Collapsing a tangle of debts into the fewest transfers needs a ledger of who paid what across many expenses. A one-expense calculator cannot do that and should not pretend to. What it produces — an exact per-person breakdown — is the input a settle-up starts from.
In Splitwise
Multiple currencies
Dollars on screen, currency-agnostic underneath
The arithmetic is all integer cents, so it is right in any currency, but the output is formatted in US dollars and there is no exchange-rate conversion. Splitting in euros gives you correct numbers with the wrong symbol in front of them.
Type any of these into the calculator above and you will get these figures back.
Equal split
A $147.85 restaurant bill, four people, nobody itemizing.
$147.85 does not divide by four. Rounding everyone to $36.96 would leave the table a penny short of the bill, so the odd cent goes to the first person in the list and the four figures come to $147.85 exactly.
By share
$2,400 of rent, three roommates earning $7,000, $5,000, and $4,000 a month. Enter the incomes as shares.
Everyone pays 15% of what they earn. This is usually what people mean by a "fair" split once incomes are far apart, and it is the one an equal split gets most wrong — a three-way even split would cost the lowest earner 20% of their income and the highest earner 11%.
By share
A $1,310 rental. Two people stay all seven nights, one stays four, one stays two. Enter the nights as shares.
That is $65.50 a night each — the figure the group would otherwise have argued about for twenty minutes on the drive home. Room quality can ride in the same weight: count a private room as more shares than a bunk and the split absorbs both variables at once.
Most pages that rank for “free splitwise calculator” put an email box between you and the number. This one puts the number first. The total, the method, and the per-person breakdown are worked out in the page as you type — no server computes them, and nothing about the calculation is written down.
The only field that asks for an email address is the optional SuperDivide early-access signup underneath the result, and it appears after you already have your answer. Beyond that, the page counts anonymous usage the way the rest of the site does — which method was used, how many people, and the total — and that is all.
A calculator is a smaller thing than an expense app, and pretending otherwise would waste your time.
Refresh the page and the numbers are gone. That is the right trade for a bill at a table and the wrong one for a household you are running month to month.
One expense at a time. Splitwise keeps a live balance per person across every expense in a group, which is the whole reason it is an app and not a page.
Nobody else sees the calculation, there is nobody to add to it, and nothing nudges anyone to pay. Getting the figures to the other three people is still your job.
You type the total. Splitwise offers receipt scanning and itemization on its Pro plan; SuperDivide does line-item extraction in the app.
Splitwise handles multi-currency groups with conversion. Here the arithmetic is currency-neutral but the formatting is not.
This runs in a browser tab. Splitwise has established iOS and Android apps with offline entry, which a web page cannot match.
And a calculator is not a reason to switch apps
Splitwise has a free tier, native iOS and Android apps, receipt scanning on its Pro plan, mature exports, payment hand-off in supported regions, and years of network effect — most of the people you split with already have it installed. If it is working for you, keep it and bookmark this page for the one-off splits it makes you open an app for.
Running balances that survive a closed tab, receipts turned into line items you can assign person by person, settlement records so a paid debt stays paid, spending analytics by category and person, comments when someone disputes a figure — that is an application, and it is what SuperDivide is.
It has no free tier: $3.99 a month or $29 a year, all features, after a 14-day trial that does not ask for a card. If what you actually want is a decision between the two products, the comparison is the longer and more honest read, migration caveats included.
