Asset & Debt Inventory
An itemised list with honest subtotals: every currency kept apart, every blank counted as unknown rather than as nothing.

What you own
Use a label you would recognise. Never write a full account number — the last few digits are enough to tell two accounts apart, and this tool never asks for more.
What you owe
Enter what is still outstanding, as a positive amount. Linking a debt to an item is context for whoever reads this; it is not a second deduction, and the totals do not count it twice.
Inventory
A separate figure you can enter yourself for a share you consider yours. It is never derived from the whole-item value, and the word “joint” divides nothing here.
How the totals are worked out
Three lines per currency, and nothing else:
known asset subtotal = the asset estimates you entered
known debt subtotal = the outstanding balances you entered
listed balance estimate = assets − debts
Every figure is held as an exact decimal rather than as a floating-point number, so a hundred entries of 0.10 come to exactly 10.00 and the printed total always matches the column above it.
A negative result is a normal answer, and it prints as one: owing more than you own is a fact, not an error. Negative entries are refused instead, with a note explaining that a debt is recorded as a balance owed rather than as a minus figure.
What this is not: it is not the value of your estate for probate, for settlement, or for tax anywhere. What counts, what is exempt and what is valued differently are all questions for someone qualified where you live. This is a list, with subtotals.
