Financial affidavit tools compared

Published October 27, 2026

If you need monthly figures for California's FL-150 or Florida's Form 12.902(b) or (c), there are several ways to get them, from a free calculator to attorney software to a spreadsheet. This page compares them. It is published by Financial Affidavit Numbers, so read it with that in mind; we have tried to say plainly what each of the others does better. Facts about other tools come from their own websites as we read them in October 2026, and prices change. This is general information, not legal advice.

What each one does better

californiafinancialdisclosure.com is free and California-specific, with county pages, a disclosure deadline tracker and an FL-142 tool, none of which we have. If you already know your monthly figures and only need to convert a pay schedule, its calculator is enough. The site also promotes a separate product, EvidenceCanvas by Casewright, that it says reads 12 to 24 months of statements; its sign-up link did not load when we checked on October 27, 2026.

Bankflow reads scans and photos of statements; we do not yet, so scanned months have to be typed in. It exports to twelve formats, including QuickBooks and Xero, and is built for bookkeepers handling many clients. It knows nothing about family law forms: you would still sort its output into the form's lines yourself.

SpendSum runs in the browser like we do, and its free plan needs no signup. For one account and the last 90 days of CSV it costs nothing. The FL-150 averages a year, so 12 months of several accounts would need Pro.

Instafill.ai puts your answers into the FL-150 PDF itself, which we do not do. It does not say it works out the figures from statements, so you bring the numbers.

SplitSheet is built for attorneys and does more on the investigative side: flags for possible dissipation, splitting shared expenses between the parties, and pricing per case. If you have a lawyer, ask whether they use it or something like it.

A spreadsheet is free and fully under your control. If your bank gives CSV downloads for the whole year and you are comfortable with a pivot table, it does the job. The spreadsheet guide has a step-by-step method.

Have your statements as PDF, CSV or OFX? Financial Affidavit Numbers reads them in your browser, checks that each statement reconciles, and sorts the transactions into the form's own lines. You confirm every category and decide every flagged item. The worksheet gives each line's monthly average and the statement lines behind it:
WORKSHEET: FL-150 ITEM 13, AVERAGE MONTHLY EXPENSES
13d Groceries and household supplies $612.40
average monthly, 12 months, 148 transactions, schedule p. 4
13e Eating out $187.15
average monthly, 12 months, 61 transactions, schedule p. 5
13f Utilities (gas, electric, water, trash) $241.08
average monthly, 12 months, 36 transactions, schedule p. 5
See your own figures free → $29 once, only if you want the full worksheet.

What to look for, whichever you use

Where a lawyer or self-help center fits

Which form to use, what counts as income and how to present a change in circumstances are legal questions, not arithmetic. No calculator answers them, ours included; a lawyer or your court's free self-help center can.

Financial Affidavit Numbers is a worksheet: monthly figures by form line and the statement lines behind them. It does not fill in, prepare or file the FL-150 or the Florida affidavit; you copy the numbers onto the court's form.

Common questions

Is there an FL-150 calculator?

Yes. californiafinancialdisclosure.com has a free FL-150 calculator that converts a pay amount and frequency to a monthly figure and adds four expense fields. You type the amounts in. Tools that read bank statements are listed on this page.

Is there an app that reads bank statements for a financial affidavit?

Generic statement tools such as Bankflow and SpendSum read statements, but they are not built around the forms' lines. SplitSheet reads statements for attorneys at $99 per case after a free first case. Financial Affidavit Numbers reads them and sorts transactions into the FL-150 or Florida form's own lines.

Can you use software to fill out the FL-150?

Instafill.ai says it fills the FL-150 from your answers or an uploaded document, at $19.99 a month after a 7-day trial. Financial Affidavit Numbers does not fill in the form; it gives the figures, and you copy them onto the court's form.

Is a spreadsheet good enough for a financial affidavit?

For many people, yes: export a year of CSV transactions, sort them into the form's lines, remove transfers and card payments, and divide by the number of months. Tools save time mainly with PDF statements, reconciliation and the schedule of transactions.
