What Is Bank Reconciliation?
Bank reconciliation is the process of comparing a bank statement balance with the company’s internal book or cash ledger balance and explaining the differences. The goal is to find the correct cash balance after accounting for timing differences, unrecorded bank transactions, errors, and adjustments. A bank reconciliation statement acts as a bridge between what the bank shows and what the company’s accounting records show.
Bank reconciliation supports accurate financial reporting, cash control, fraud detection, and clean bookkeeping. Modern businesses may reconcile daily, weekly, or monthly depending on transaction volume and risk. NetSuite describes bank reconciliation as the process of comparing a company’s bank statement with its cash records to make sure balances and transactions match, and notes that it helps cash-flow management, error detection, and fraud review. :contentReference[oaicite:1]{index=1}
Bank Reconciliation Formula
The calculator uses two sides: adjusted bank balance and adjusted book balance.
\[ Adjusted\ Bank = Bank\ Statement\ Balance + Deposits\ in\ Transit - Outstanding\ Checks + Bank\ Errors\ Add - Bank\ Errors\ Deduct \]
\[ Adjusted\ Book = Book\ Balance + Interest + Bank\ Collections - Bank\ Fees - NSF + Book\ Error\ Add - Book\ Error\ Deduct + Other\ Adds - Other\ Deductions \]
The reconciliation is complete when:
\[ Adjusted\ Bank = Adjusted\ Book \]
If the adjusted balances do not match, the difference is:
\[ Difference = Adjusted\ Bank - Adjusted\ Book \]
Bank-side Adjustments
Bank-side adjustments usually involve timing differences. These are items the company has recorded but the bank has not yet processed. They usually do not require journal entries because the books already include them.
Deposits in Transit
A deposit in transit is a deposit recorded by the company but not yet shown on the bank statement. Since the company has already added the deposit to its books, the deposit is added to the bank statement balance during reconciliation.
\[ Adjusted\ Bank = Bank\ Balance + Deposits\ in\ Transit \]
For example, if the bank balance is \(25,000\) and deposits in transit are \(3,000\), the adjusted bank side increases to \(28,000\) before other adjustments.
Outstanding Checks
Outstanding checks are checks or payments recorded by the company but not yet cleared by the bank. Since the company has already reduced its book cash balance, these checks are subtracted from the bank statement balance.
\[ Adjusted\ Bank = Bank\ Balance - Outstanding\ Checks \]
For example, if outstanding checks total \(4,200\), subtract \(4,200\) from the bank side.
Book-side Adjustments
Book-side adjustments are items the bank has recorded but the company has not yet recorded. These usually require journal entries.
Bank Fees
Bank service charges reduce cash but may not be recorded in the company books until the bank statement is received.
\[ Book\ Balance = Book\ Balance - Bank\ Fees \]
Interest Earned
Interest credited by the bank increases cash and interest income. If the company has not recorded the interest, it is added to the book balance.
\[ Book\ Balance = Book\ Balance + Interest\ Earned \]
NSF Checks
NSF means non-sufficient funds. If a customer payment is returned by the bank, cash must be reduced in the books and the receivable may need to be restored.
\[ Book\ Balance = Book\ Balance - NSF\ Checks \]
Bank Collections
Sometimes the bank collects money directly for the business, such as notes receivable, lockbox collections, or card settlements. If not yet recorded in the books, these amounts are added to the book balance.
\[ Book\ Balance = Book\ Balance + Bank\ Collections \]
Common Bank Reconciliation Format
| Side | Additions | Deductions | Usually needs journal entry? |
|---|---|---|---|
| Bank side | Deposits in transit, bank errors that understated balance | Outstanding checks, bank errors that overstated balance | No, unless correcting bank error in books is needed later |
| Book side | Interest earned, bank collections, direct deposits, book errors increasing cash | Bank fees, NSF checks, automatic payments, book errors decreasing cash | Yes, usually |
Worked Example
Suppose the bank statement balance is \(25,000\), deposits in transit are \(3,000\), and outstanding checks are \(4,200\). The adjusted bank balance is:
\[ Adjusted\ Bank=25,000+3,000-4,200=23,800 \]
Suppose the book balance is \(23,150\), interest earned is \(75\), bank collections are \(1,000\), and bank fees are \(25\). The adjusted book balance is:
\[ Adjusted\ Book=23,150+75+1,000-25=24,200 \]
The difference is:
\[ Difference=23,800-24,200=-400 \]
A difference of \(-400\) means the adjusted book balance is \(400\) higher than the adjusted bank balance. The accountant should investigate missing checks, missing deposits, posting errors, bank errors, duplicate entries, or incorrect inputs.
Suggested Journal Entries
Bank-side timing items, such as deposits in transit and outstanding checks, usually do not need journal entries because the company already recorded them. Book-side items usually require journal entries.
| Item | Possible entry | Explanation |
|---|---|---|
| Bank fee | Debit Bank Charges Expense; Credit Cash | Reduces book cash |
| Interest earned | Debit Cash; Credit Interest Income | Increases book cash |
| NSF check | Debit Accounts Receivable; Credit Cash | Reverses failed customer payment |
| Bank collection | Debit Cash; Credit Notes Receivable / Accounts Receivable / Revenue | Records cash collected directly by bank |
| Book error | Depends on error | Corrects wrong amount, account, or direction |
Why Bank Reconciliation Matters
Bank reconciliation matters because cash is one of the most sensitive accounts in accounting. Errors, duplicate payments, missing deposits, fraud, bank charges, failed customer payments, and timing differences can all distort the cash balance. Washington State Auditor guidance states that the purpose of bank reconciliation is to compare bank cash and investment balances with accounting records and reconcile or follow up on differences. :contentReference[oaicite:2]{index=2}
A clean reconciliation gives managers, owners, auditors, and accountants more confidence that the reported cash balance is accurate. It also helps identify unauthorized transactions, late deposits, checks that have not cleared, and possible bookkeeping mistakes.
Bank Reconciliation Checklist
- Start with the ending bank statement balance.
- Add deposits in transit.
- Subtract outstanding checks and uncleared payments.
- Correct bank errors if identified.
- Start with the ending book cash balance.
- Add bank credits such as interest and collections.
- Subtract bank fees, NSF items, automatic withdrawals, and unrecorded payments.
- Correct book errors.
- Compare adjusted bank balance and adjusted book balance.
- Investigate any difference.
- Record necessary journal entries for book-side adjustments.
Common Causes of Differences
| Difference | Typical side | Reason |
|---|---|---|
| Deposit in transit | Bank side | Company recorded deposit; bank has not processed it yet |
| Outstanding check | Bank side | Company recorded payment; bank has not cleared it yet |
| Bank service charge | Book side | Bank deducted fee; company has not recorded it |
| Interest income | Book side | Bank credited interest; company has not recorded it |
| NSF check | Book side | Customer payment failed after company recorded receipt |
| Autopay or ACH debit | Book side | Bank processed payment not recorded in books |
| Book error | Book side | Wrong amount, duplicate entry, or wrong direction posted |
| Bank error | Bank side | Bank posted wrong amount or transaction to account |
Best Practices
Reconcile regularly. Monthly reconciliation is common, but high-volume businesses often reconcile weekly or daily. Save bank statements, reconciliation reports, support for outstanding items, and evidence of journal entries. Review old outstanding checks and deposits. Separate duties where possible so the person reconciling the account is not the same person authorizing payments. Investigate unusual differences quickly.
Small differences should not be ignored without review. A small difference may reveal a data-entry mistake, a bank fee, a duplicated transaction, or an incorrect posting. Large differences require immediate investigation.

Why This Page Does Not Include Exam Score Tables
A Bank Reconciliation Calculator is an accounting and bookkeeping tool, not an exam score calculator. Score guidelines, score tables, and next exam timetables do not apply directly to this page. The equivalent useful material is reconciliation formulas, bank-side and book-side adjustment logic, journal entries, worked examples, internal control notes, and a practical reconciliation checklist.
Bank Reconciliation Calculator FAQs
What is bank reconciliation?
Bank reconciliation is the process of comparing the bank statement balance with the book cash balance and explaining differences until the adjusted balances match.
What is the adjusted bank balance formula?
\(Adjusted\ Bank=Bank\ Balance+Deposits\ in\ Transit-Outstanding\ Checks\pm Bank\ Errors\).
What is the adjusted book balance formula?
\(Adjusted\ Book=Book\ Balance+Interest+Collections-Fees-NSF\pm Book\ Errors\).
What are deposits in transit?
Deposits in transit are deposits recorded in the books but not yet shown on the bank statement.
What are outstanding checks?
Outstanding checks are checks or payments recorded by the company but not yet cleared by the bank.
Do deposits in transit need journal entries?
Usually no. They are timing differences already recorded in the books.
Do bank fees need journal entries?
Usually yes. Bank fees reduce cash and must be recorded in the books if not already posted.
What does it mean if adjusted balances do not match?
It means there is still an unreconciled difference. Check missing deposits, checks, bank charges, NSF items, errors, duplicate postings, or incorrect inputs.
