Budgeting
You can base one account's figures on another account's total, and pick the account from a list instead of typing its number.
Some costs are a proportion of another cost — a contingency on a department, an assistant paid a share of the principal's fee. `ACCOUNT` expresses that directly instead of you recalculating it by hand.
In a formula field, open the dropdown and take **Functions ▸ ACCOUNT**, then pick the account from the list that appears. The whole call is written for you:
Picking from the list rather than typing the number matters: a number typed from memory is the most common way to produce a formula that looks right and refers to the wrong line.
Ten per cent of account 1101. Put that in a Price/Unit with a Quantity of 1, and the account tracks the other one automatically.
The account's **total** — quantity × price × factor, and for an account with subaccounts the sum of them. Not its quantity: for that see [use quantities in formulas](/kb/article/use-quantities-in-formulas).
An account cannot reference itself, directly or through a chain that comes back to it. If two accounts each need the other, one of them needs a variable or a subtotal in between.
**When the account is deleted.** The formula keeps its reference and the cell shows a red frame. The reference has nothing at the other end; fix it by pointing at another account or removing the formula.
