Treasury Bank Reconciliation: Complete Excel Guide for Treasurers
# Treasury Bank Reconciliation: Master Your Cash Position with Excel Bank reconciliation is one of your most critical responsibilities. Every month, discrepancies between your company's records and bank statements can hide errors, fraud, or timing issues that directly impact your cash flow visibility and financial reporting accuracy. Without a systematic reconciliation process, you risk overlooking unauthorized transactions, duplicate charges, or missing deposits—problems that compound quickly and undermine stakeholder confidence in your financial controls. This is where Excel becomes your strategic advantage. Rather than manually comparing line items in spreadsheets, a well-designed reconciliation template automates the matching process, flags discrepancies instantly, and creates an audit trail that satisfies both internal and external auditors. In this guide, you'll discover how to build a robust bank reconciliation workflow in Excel that saves hours each month while strengthening your internal controls. Whether you're managing a single account or multiple bank relationships, the formulas and techniques covered here will streamline your process and eliminate reconciliation bottlenecks. We've also prepared a free Excel template you can download immediately to get started—no complex setup required. Let's transform bank reconciliation from a time-consuming chore into a controlled, efficient process.
The Problem
Bank reconciliation is a treasurer's monthly headache. You receive statements from multiple banks, each with different timing formats and transaction descriptions. Deposits show up on different dates in the bank system versus your internal records. Checks clear unpredictably. Wire transfers, ACH payments, and service fees scatter across statements without clear categorization. You're manually matching hundreds of transactions, cross-referencing dates and amounts, hunting for that frustrating $0.47 discrepancy that throws off your entire reconciliation. Outstanding checks from last month still haven't cleared. Deposits in transit create confusion. You're spending hours in spreadsheets, copying figures, recalculating, and verifying—work that's repetitive, error-prone, and takes you away from strategic financial decisions. By month-end, you're stressed, exhausted, and the reconciliation still isn't complete. You need a smarter system that automates matching, flags discrepancies, and saves you days of tedious work.

Step-by-Step Tutorial
Create the Bank Statement section
Set up the first section to capture bank statement data. Create columns for Transaction Date, Description, Bank Debit, Bank Credit, and Running Balance. This section represents the official bank statement provided by your financial institution.
Start in cell A1 and leave row 1 for headers. Use a light blue background color to distinguish the bank statement section from the general ledger section below.
Create the General Ledger section
Below the bank statement section (around row 20), create a similar table structure with columns for Transaction Date, Description, GL Debit, GL Credit, and Reference Number. This represents your company's internal accounting records that need to be reconciled against the bank statement.
Use a light green background to visually separate the GL section. Leave at least 3 rows between sections for clarity.
Add summary sections for both sides
Create summary rows at the bottom of each section to calculate total debits and credits. These totals will help identify discrepancies quickly. Add rows for 'Total Debits' and 'Total Credits' with SUMIF formulas to automatically calculate column totals.
=SUMIF(A2:A15,">0",C2:C15)Place summary rows immediately below each section's data for easy reference and comparison.
Create a reconciliation adjustment section
Add a new section dedicated to recording timing differences and adjustments such as outstanding checks, deposits in transit, bank fees, and interest earned. Include columns for Adjustment Description, Amount, and Reconciling Item Type (Outstanding Check, Deposit in Transit, etc.).
Use data validation dropdown lists for the 'Reconciling Item Type' column to ensure consistent categorization of adjustments.
Calculate adjusted balances using IF formulas
Create formulas to calculate the adjusted bank balance and adjusted GL balance by adding or subtracting reconciliation items. Use IF statements to properly categorize whether each adjustment increases or decreases the balance based on its type.
=IF(E5="Outstanding Check",Bank_Total-F5,IF(E5="Deposit in Transit",Bank_Total+F5,Bank_Total))Create a summary cell that shows 'Reconciliation Complete' only when adjusted balances match using an IF statement: =IF(Adjusted_Bank=Adjusted_GL,"Reconciliation Complete","Variance: "&Adjusted_Bank-Adjusted_GL)
Add a matching reference table with VLOOKUP
Create a helper table that tracks which GL transactions have been matched to bank transactions using VLOOKUP. Add a 'Matched' column in the GL section that references bank transaction dates to identify unmatched items automatically.
=IF(ISNUMBER(MATCH(A2,Bank_Dates,0)),"Matched","Unmatched")Use conditional formatting to highlight unmatched transactions in red, making it easy to spot reconciliation gaps at a glance.
Create variance analysis with SUMIF formulas
Build a variance analysis section that uses SUMIF to automatically sum unmatched debits and credits from both the bank and GL sections. This helps quickly identify the source and amount of discrepancies requiring investigation.
=SUMIF(Matched_Status,"Unmatched",GL_Debit_Column)-SUMIF(Matched_Status,"Unmatched",Bank_Debit_Column)Add a comment box next to the variance amount to document the reason for any discrepancy and the date it was identified for audit trail purposes.
Add reconciliation sign-off section
Create a final section with fields for Preparer Name, Preparer Date, Reviewer Name, Reviewer Date, and Approval Status. Include a formula that prevents approval unless the reconciliation is complete and balanced.
=IF(AND(Adjusted_Bank=Adjusted_GL,Preparer_Name<>""),"Ready for Review","Incomplete")Use data validation to create a dropdown for Approval Status with options: 'Pending', 'Approved', or 'Rejected' to maintain proper workflow control.
Format and protect the template
Apply professional formatting including borders, number formatting for currency, and freeze panes at the header row. Protect the formula cells while leaving data entry cells editable to prevent accidental formula corruption.
Use Format > Cells to apply currency format with 2 decimal places. Freeze panes at row 2 for easy scrolling. Protect the sheet with Format > Protect Sheet, allowing users to edit only unprotected cells.
Create a dashboard summary tab
Add a new worksheet tab that summarizes key metrics from the reconciliation including reconciliation date, total variance, number of unmatched items, and reconciliation status. Use formulas to pull data from the main reconciliation sheet for executive reporting.
=COUNTIF(Matched_Status,"Unmatched")&" items require attention"Add a timestamp formula =NOW() in the dashboard to automatically record when the reconciliation was last updated, ensuring stakeholders know the currency of the data.

Monthly Corporate Bank Account Reconciliation
Thomas, treasurer at a mid-size manufacturing company, must reconcile the company's main operating account every month-end. He receives bank statements with 150+ transactions and needs to match them against the accounting ledger to identify discrepancies before closing the books.
Bank statement balance: $287,450 | Ledger balance: $289,200 | Outstanding checks: Check #4521 ($1,200), Check #4523 ($850) | Deposits in transit: $2,000 (deposited 3/31, cleared 4/2) | Bank fees charged: $150 (not yet recorded)
Result: Reconciliation showing: Bank balance $287,450 + Deposits in transit $2,000 - Outstanding checks $2,050 = Adjusted bank balance $287,400. Ledger balance $289,200 - Unrecorded bank fees $150 - Duplicate entry correction $1,650 = Adjusted ledger balance $287,400. Both sides match, confirming accurate accounting.

Pro Tips
Master SUMIF for Instant Reconciliation Status
Create a dynamic reconciliation summary that automatically calculates unmatched transactions. Use SUMIF to compare bank statements against your ledger in seconds. This eliminates manual counting and reveals discrepancies instantly. Set up two columns: one for bank totals, one for ledger totals, then use SUMIF to flag differences by transaction type or date range.
=SUMIF(BankStatement!$A:$A,LedgerData!A2,BankStatement!$C:$C)-SUMIF(LedgerData!$A:$A,LedgerData!A2,LedgerData!$C:$C)Use Conditional Formatting to Spot Unmatched Items Instantly
Apply conditional formatting rules (Home > Conditional Formatting > Highlight Cell Rules) to color-code unreconciled transactions in red and cleared transactions in green. This visual approach saves time during month-end closes and makes audit trails immediately obvious. Create a 'Status' column with values like 'Matched', 'Pending', or 'Discrepancy'.
Build a Two-Way Lookup Matrix with INDEX-MATCH
Instead of manually searching for matching transactions, create a helper column using INDEX-MATCH to automatically find corresponding entries between bank and ledger. This reduces human error and accelerates reconciliation. Match on amount + date combination for precision.
=IFERROR(INDEX(BankData!$C:$C,MATCH(1,(BankData!$B:$B=LedgerData!B2)*(BankData!$C:$C=LedgerData!C2),0)),"No Match")Create a Pivot Table Dashboard for Variance Analysis
Use a Pivot Table to instantly summarize reconciliation variances by account, transaction type, or date range. This executive-level view reveals patterns (e.g., timing differences, recurring errors) and supports faster decision-making. Refresh with Ctrl+Shift+F5 after updating source data.
