Free bill splitter: split shared expenses and settle up in the fewest payments
Record who paid for what, split equally or by percentage, custom amount, or item, and reduce the group to a short list of clear repayments. Your own budget, income and balances are never part of a group.
What a bill splitter is actually for
Four people share a holiday. One books the flights, another puts the house on their card, a third covers most of the food, and the fourth pays for the car and the fuel. By the end nobody can say who is up and who is down, and the group settles it by guessing, or by nobody mentioning it again.
A bill splitter exists to end that. You record what each expense cost and who actually paid it. The tool works out what each person owes against what they already put in, and turns the difference into a short list of repayments. Nobody has to remember anything, and nobody has to be the person who brings it up.
Four ways to divide an expense
Equally is the default and it covers most of a trip: one bill, everyone in, split down the middle. Wiggle Budget also handles the three cases where equal is wrong.
By percentage, when the shares are fixed but unequal, two people on a joint tenancy paying 60/40 because one has the bigger room. By custom amount, when you already know the exact figures and want them recorded rather than derived. By item, when one receipt contains several things and different people are on the hook for different lines, which is what a restaurant bill or a supermarket shop actually looks like.
A single group can mix them. The holiday house splits by percentage, the supermarket run splits by item, the taxi splits equally, and the settlement at the end accounts for all three together.
Why the pennies come out right
Splitting $10 three ways does not produce three equal shares, and a tool that rounds each one to $3.33 quietly loses a penny. Over a long trip that error compounds into a balance nobody can reconcile against the receipts.
Wiggle Budget does the arithmetic in whole cents and hands out the remainder a cent at a time, so the shares always add back to exactly what was spent. If you total the split, you get the bill. That is not a nice detail, it is the difference between a settlement people trust and one they argue about.
The fewest repayments, not the most
Once everyone’s balance is known there are many ways to clear it, and most of them are bad. Paying each person back for each expense they covered turns a weekend away into fifteen bank transfers.
Instead the group is reduced to a settlement plan: the person owed the most is paid by the person who owes the most, repeatedly, until every balance is zero. A four-person trip with a dozen expenses usually collapses into two or three transfers. Payments you have already made are recorded, so the plan shrinks as people settle up rather than resetting.
Your budget stays yours
This is the part most shared-expense apps get wrong. Splitting a bill with someone should not give them a window into your finances.
A group in Wiggle Budget sees the shared expenses and the repayments between them. It does not see your accounts, your income, your debts, or your safe-to-spend number, and there is no setting that would let it. Financial fields are encrypted before they are stored, and there is no bank connection anywhere in the product to expose in the first place.
What happens after the split
Every splitter can tell you that you owe a friend $180. Almost none of them can tell you whether paying it this Friday is a good idea.
That is the part Wiggle Budget adds. Once you know what you owe, the same app can place that repayment on your own timeline, beside rent, payday and everything else already committed, and show you the lowest point your balance reaches before and after you send it. The group sees a settled bill. You see whether settling it on Friday leaves you short on the 28th. Nobody else sees the second half.
Budget questions from real discussions
These public discussions describe individual experiences, not a survey or endorsements of Wiggle Budget. The examples below are illustrative.
Equal shares can still put someone over budget.
In r/poor, a reader described ordering less to stay within budget, then receiving an equal share of a larger restaurant bill. Several replies suggested agreeing on separate checks before ordering.
Agree on the split before someone pays. Equal shares suit a shared purchase; itemized or custom shares can suit different orders. Include tax, tips and shared items in that agreement. A calculator can apply the shares, but it cannot decide what everyone considers fair.
Example: two agreed shares are $18 and $42, including all charges. Splitting the $60 total equally asks the first person for $12 more than their agreed share. If that person pays the whole bill, the other owes $42. Until repayment arrives, the payer has funded the full $60.
Bill splitting questions
- What does the bill splitter cost?
- Every new account starts with a 30-day Pro Max trial and no card is required to begin it, so you can run a whole trip through the splitter before deciding anything. After the trial it is part of the paid plans; the pricing page always shows what is current. There is never a per-group or per-person charge.
- Do the other people in the group need an account?
- You can add people as participants and record everything yourself, which is what most groups do for a one-off trip. Nobody has to sign up for the split to be tracked and settled correctly.
- Can the group see my budget, income, or bank balance?
- No. A group shows the shared expenses and the repayments between its participants. Your accounts, income, debts, and safe-to-spend figure are never part of a group and cannot be shared into one. Financial fields are encrypted before they are stored, and Wiggle Budget has no bank connection at all.
- How do you split a bill when people owe different amounts?
- Use percentage mode when the shares are fixed but unequal, such as roommates paying 60/40 for different rooms. Use custom amounts when you already know each figure. Use itemised mode when one receipt covers several things and different people are responsible for different lines. A group can mix all of these across different expenses.
- What if the split does not divide evenly?
- The maths runs in whole cents and distributes the remainder one cent at a time, so the shares always add back to exactly the amount spent. Splitting $10 between three people produces $3.34, $3.33 and $3.33, not three shares that quietly lose a penny.
- How does it decide who pays whom?
- It reduces the group to the fewest transfers that clear every balance, repeatedly matching the person owed the most with the person who owes the most. A dozen shared expenses across four people usually settles in two or three payments rather than a dozen.
- Is this a Splitwise alternative?
- It covers the same ground: shared expenses, unequal shares, itemised receipts, and a minimised settlement. The difference is what sits behind it. Wiggle Budget is a forward-looking budgeting app first, so once you know what you owe you can also see what paying it does to your own month. And it has no bank connection to give away.
- Can I record a repayment that has already happened?
- Yes. Recorded payments are subtracted from the outstanding balances, so the settlement plan shrinks as people pay each other back instead of showing the original amounts forever.
