The Trial Balance
List every account balance and confirm total debits equal total credits before you build statements.
TL;DR
- List every account's balance in a
trialBalance, debits and credits. - Confirm the two column
totalsare equal. - Treat a matching
trialBalanceas a checkpoint, not a guarantee.

- Run a

Warnings
- A balanced
trialBalancedoes not prove the books are correct; it can still hide an entry posted to the wrong account. - It also misses a transaction left out entirely, since a missing
entrynever unbalances the two columns.
In Practice
Total the debit and credit balances and confirm they match.
Your ledger shows Cash $12,000, Equipment $8,000, and Rent Expense $3,000 as debit balances, and Accounts Payable $3,000, Loan Payable $10,000, Owner's Capital $5,000, and Sales $5,000 as credit balances.
- Debit balances: $12,000 + $8,000 + $3,000 = $23,000.
- Credit balances: $3,000 + $10,000 + $5,000 + $5,000 = $23,000.
- Compare the totals: $23,000 versus $23,000.
- They match, so the ledger is arithmetically in balance.
Both columns total $23,000, so the trial balance is in balance.
Equal totals confirm the math, but not that every entry is in the right account.
FAQ
A trial balance is a list of every account in the ledger with its ending balance, placed in a debit column or a credit column. You total both columns, and they should be equal. It is a periodic checkpoint that confirms the ledger is arithmetically in balance before you use it to build financial statements.
Because double-entry records equal debits and credits for every transaction. When you add up all the debit balances and all the credit balances, the two sums should match. If they do not, an entry was posted to only one side, entered twice on one side, or recorded with a typo, so the totals reveal that a problem exists.
Several. It will not catch a transaction you forgot to record, an entry posted to the wrong account of the same type, or two mistakes that happen to cancel out. Because these leave the two columns equal, the trial balance still looks fine. It proves the math balances, not that every entry is right.
It is the trial balance run again after adjusting entries, the end-of-period updates for things like depreciation, accrued wages, and prepaid expenses. The unadjusted version comes first, then adjustments are added, and the adjusted trial balance is what the financial statements are actually built from.
