An OurFamilyWizard alternative for the expense maths
Just need to settle shared kid costs from a list? One parent can do it in a browser, without a subscription for each of you.
OurFamilyWizard is a full co-parenting platform — messaging, calendar, records and an expense log. Its pricing page lists plans priced per parent, from $110 a year, and its plans article describes what each plan includes. (Both read 2026-11-04.) If you're ordered to use it, or want everything in one place, it's a sensible choice.
Kidtally is for the narrower job: you already keep receipts in a spreadsheet or notes, and want an exact settle-up at your agreed ratio. One parent can run it; nothing is uploaded.
Load one row per expense: which parent paid, the amount and who shares it — all splits it by your agreed ratio (Maria:60; Sam:40), Maria; Sam makes that row 50/50, and a single other name records a payment or reimbursement between you. Add an optional category (Childcare, Medical, School…) to get totals per category. Each share is split in whole cents, so both balances net to exactly zero.
Your expenses stay on your computer
Kidtally reads your file with JavaScript in this browser tab. Names and amounts are never uploaded and nothing is saved — close the tab and it's gone. Neither parent needs an account.
How it works
- List the kid costs — who paid, amount and who shares it — in the template, or try the sample.
- Enter your agreed ratio, or use 50/50.
- Share the statement: each parent's share and the amount still owed.
FAQ
Is my data uploaded?
No. Your files are read by JavaScript in your browser tab and never sent to us or anyone else. Expenses aren't stored, so closing the tab clears them. The currency, ratio and split can be saved in this browser if you ask; the statement name never is.
Where does the ratio come from?
Usually your parenting plan, separation agreement or support order — often each parent's share of combined income (for example $60,000 and $40,000 gives 60/40). Kidtally doesn't work out what you're required to pay; it applies the ratio you enter.
How do I write the split?
all (or blank) splits the row by your agreed ratio. Maria; Sam makes that row 50/50, and Maria:3; Sam:1 is a custom split. A single name other than the payer records a payment between you, like Sam paying Maria back.
How are reimbursements and insurance handled?
When one parent pays the other, enter a row paid by them with only the other parent in the split — it counts as a payment, not a shared cost. When insurance or a school pays something back, enter it as a negative amount on the row of the parent who got the money.
How are the cents handled?
Each share is worked out by rounding down and giving the leftover cents to the largest remainders, so shares always add up exactly to the expense and both balances net to zero.
How is this different from OurFamilyWizard?
OurFamilyWizard is a full co-parenting platform with messaging, calendars and an expense log, and its plans are priced per parent. Kidtally only does the expense maths from a list you already have, one parent can run it, and nothing is uploaded. If a court requires a specific app, use that.
What's free?
Both balances, the amount owed, every flag, 3 what-ifs and 12 expenses on screen and in print (with a footer). Pro shows every expense and every what-if and adds a statement for each parent, the Excel workbook and CSV exports.
Is this legal or financial advice?
No. Kidtally does the arithmetic on the expenses and ratio you enter. Your order or agreement decides which expenses are shared.
