What it means
A ledger account is just two columns of numbers, debits on the left and credits on the right. Adding each column gives you its footing, and the difference between the two footings is the account balance.
The mechanics are trivial but the purpose is not. Footings are how a bookkeeper converts a long list of individual transactions into a single meaningful number that can be carried into the trial balance and then into the financial statements.
An account with a larger debit footing carries a debit balance, which is normal for assets and expenses. A larger credit footing gives a credit balance, which is what you expect for liabilities, equity and revenue, so a balance falling on the wrong side is an instant flag that something has been posted incorrectly.
In manual bookkeeping the footing was often written small and in pencil beneath the column, which is why it was sometimes called a pencil footing. Accounting software calculates footings automatically now, but the concept survives because reviewers still check that column totals agree.
The term also appears in a wider sense. Analysts sometimes describe the total of one side of a balance sheet as its footing, and in banking the phrase total footings is occasionally used to mean total assets, so context matters when you hear it.
Cross-footing is the companion check worth knowing. It means adding across rows as well as down columns and confirming both grand totals agree, which is how spreadsheet errors in a schedule get caught before the numbers travel further.
In practice
Real-world examples.
Example
A bookkeeper at a plumbing firm foots the accounts receivable ledger and gets $184,300, but the control account shows $184,750. The $450 gap sends her back through the month's postings, where she finds an invoice entered twice.
Example
An auditor reviewing a stock schedule cross-foots it, adding both down the quantity column and across the location columns. The two grand totals differ by $2,100, revealing a formula that had not been extended to the final row.
Example
A charity treasurer foots the donations account at the year end and finds a credit footing of $312,000 against debits of $4,000 in refunds. The $308,000 credit balance flows straight into the income statement as recognised donation income.
Formula
Calculation
Debit footing = Sum of all amounts in the debit column
Credit footing = Sum of all amounts in the credit column
Account balance = Debit footing - Credit footing
A small consultancy's cash account shows six entries for the month.
Debits: $12,500 received from a client, $8,300 from a second client, $4,200 from a third.
Debit footing = $12,500 + $8,300 + $4,200 = $25,000
Credits: $6,750 of salaries paid, $3,400 of rent, $5,850 of supplier invoices.
Credit footing = $6,750 + $3,400 + $5,850 = $16,000
Account balance = $25,000 - $16,000 = $9,000 debit
The $9,000 debit balance is the closing cash figure that goes into the trial balance. Because cash is an asset, a debit balance is exactly what should appear, and a credit balance here would mean the account had been overdrawn or something posted the wrong way round.Case study
Seen in the real world.
Merrow Lane Bakery is an entirely fictional business used to illustrate why footings still matter in a software age. Its owner kept the books in a spreadsheet, and at year end the accountant found that the trial balance did not agree by $1,890.
Rather than search the whole file, the accountant footed each account individually and compared the result with the spreadsheet's own totals. The supplier ledger came out $1,890 higher when added by hand, and the cause was a sum formula whose range stopped one row short of the final entry, an error the spreadsheet reported without complaint.
The illustrative point is that automation moves errors rather than removing them. Merrow Lane now foots every ledger independently once a quarter and cross-foots its main schedules, a habit that has caught three further formula errors and takes under an hour each time.
Watch out
Common mistakes.
- Assuming software makes footing unnecessary. Spreadsheet totals depend on formula ranges that quietly break when rows are inserted, so an independent check still catches real errors.
- Confusing the footing with the balance. The footing is the total of one column, while the balance is the difference between the two footings.
- Ignoring a balance that sits on the unexpected side. A credit balance in an asset account is not a rounding quirk, it almost always means a posting has gone the wrong way.
Questions
People also ask.
What is cross-footing?
It is checking a table by adding across the rows as well as down the columns and confirming that both grand totals agree.
Does every account have two footings?
In principle yes, although an account with entries on only one side has a single footing that is also its balance.
Why is the word footing used at all?
Because the total was traditionally written at the foot of the column in a paper ledger, and the name stuck long after the paper disappeared.
