Financial Fact Sheet

Mine is a simple (ish!) Google Docs file that I share with my wife. It's broken down into subheadings and under each is a table of information summarising account information. Here's what I've currently got:

Current Accounts: Account Name; Sort Code and Account Number; Account Holder (me, wife, joint); Minimum monthly pay in; How it is funded (e.g. salary, standing order from another account)

Savings Accounts: Account Name; Sort Code and Account Number; Account Holder, how it is funded (if anything)

Credit Cards: Account Name, Credit Limit, Account Holder, Whether it's paid off in full or how much is paid off and when 0% ends

Utilities and Bills: Type (e.g. Gas and Electric, Mobile Phone, Council tax), Supplier, Typical monthly cost, Renewal date

Vehicles: Type of Bill (e.g. Insurance, MOT, Tax, Breakdown cover), Supplier, Annual Cost, Renewal date

Mortgage: Supplier, Interest Rate and fixed period end, Account Number, Monthly amount

There are a few other headings but they're getting increasingly specific to us, e.g. a table of passport numbers and expiry dates.

Hope that helps and would be very interested to hear what other people do.
