How to Dispute Incorrect Bank Loan Charges in Nigeria: A Practical Guide
Taking a bank loan can help a business expand, purchase equipment, manage working capital, or overcome a temporary financial challenge. However, problems arise when a borrower discovers unexpected fees, unexplained deductions, incorrect interest calculations, or a loan balance that does not match the repayment records.
For Nigerian businesses and individuals, these discrepancies can create serious financial pressure. An unexplained charge may affect cash flow, increase the cost of borrowing, and make it difficult to determine how much is genuinely outstanding.
The good news is that borrowers do not have to accept every charge without an explanation. If you believe your bank has applied an incorrect loan charge, you can request a detailed account, challenge the disputed amount, and escalate the complaint through appropriate channels if the issue remains unresolved.
In this guide, Hardihood Associates explains how to dispute incorrect bank loan charges in Nigeria, what documents to gather, how to write an effective complaint and where to seek assistance.
What Are Incorrect Bank Loan Charges?
Incorrect bank loan charges are fees, interest amounts, deductions, or other entries that a borrower reasonably believes were applied contrary to the loan agreement, applicable rules, or the bank’s disclosed terms.
A charge is not necessarily incorrect simply because it is unexpected or expensive. The borrower should establish what was agreed, what was disclosed and how the amount was calculated.
Common examples include:
- Excess interest charges: Interest appears higher than the rate or calculation method stated in the loan agreement.
- Unexplained fees: The bank applies a fee that the borrower cannot identify in the facility letter, schedule of charges or other relevant documentation.
- Duplicate deductions: A fee, repayment or other debit appears to have been posted more than once.
- Incorrect repayment allocation: A payment is received but does not appear to have been credited correctly against the outstanding loan.
- Unexplained penalties: Default interest or late-payment fees appear inconsistent with the contractual terms or the actual repayment history.
- Incorrect loan balance: The outstanding amount does not reconcile with the original facility, repayments, interest and documented charges.
- Unauthorised deductions: Money is debited without an identifiable contractual or other lawful basis.
The key is to identify the particular entry in dispute rather than simply stating that the loan is too expensive.
Why You Should Challenge Unexplained Loan Charges
Incorrect or unexplained charges can affect both personal finances and business operations.
1. They can reduce business cash flow
Money deducted unexpectedly from a business account may have been intended for salaries, stock purchases, suppliers, rent or other operating expenses.
2. They can increase the apparent loan balance
If interest or fees have been calculated incorrectly, the balance shown by the bank may not accurately reflect the amount owed.
3. They can complicate financial reporting
Businesses need reliable records for bookkeeping, management accounts, tax preparation and financial decision-making. Unresolved loan discrepancies can make reconciliation difficult.
4. They can create repayment disputes
When a borrower and lender have different calculations, the disagreement can affect repayment negotiations and the planning of future payments.
5. They can distract management from running the business
Resolving a complex financial dispute can consume valuable time, particularly when the business has several facilities, accounts or repayment schedules.
Early investigation helps establish the facts before the disagreement becomes more difficult to resolve.
Seven Steps to Dispute Incorrect Bank Loan Charges in Nigeria
Step 1: Obtain your loan agreement and facility letter
Start with the documents governing the loan. Depending on the facility, these may include:
- The signed loan agreement.
- The facility or offer letter.
- The repayment schedule.
- Any document explaining fees and charges.
- Applicable interest-rate and default provisions.
- Statements showing loan disbursements and repayments.
- Relevant amendments, renewals or restructuring agreements.
Check the principal amount, interest rate, repayment dates, fees, default provisions and the circumstances under which the bank can change the applicable terms.
If the bank provided revised terms, request the relevant notices and documentation.
Practical tip: Do not rely solely on a verbal explanation or a summary shown in a banking application. Ask for the underlying terms and calculations in writing.
Step 2: Request a detailed loan statement and calculation
Ask the bank for a complete statement covering the period in which the discrepancy occurred.
Where necessary, request a breakdown showing:
- The original principal amount disbursed.
- The interest rate and calculation method used.
- The dates and amounts of repayments received.
- How each repayment was allocated.
- All fees, commissions and other charges.
- Any default interest or penalty calculations.
- The outstanding principal and interest.
- The calculation supporting the current settlement figure.
If the bank says a charge arose from a particular contractual clause, ask it to identify that clause and explain how the amount was calculated.
For example, a company may have taken a ₦10 million facility and later noticed an additional charge it cannot reconcile with its repayment schedule. Rather than assuming the entire charge is unlawful, the company should obtain the relevant transaction entries and request a written explanation.
This creates a factual basis for the dispute.
Step 3: Reconcile the bank’s figures with your records
Compare the bank’s statement against your own repayment records, receipts, transfer confirmations and accounting entries.
A simple reconciliation table can help:
| Item | What to check |
|---|---|
| Loan principal | Does the disbursed amount match the agreement? |
| Interest | Does the calculation follow the agreed terms? |
| Repayments | Are all payments reflected correctly? |
| Fees | Can each charge be traced to a disclosed or agreed basis? |
| Penalties | Do the dates, rates, and calculations support the amount? |
| Outstanding balance | Does the final figure reconcile with the transactions? |
Record the date of each disputed transaction, the amount, the bank’s description and your reason for questioning it.
If the calculation is complicated, an accountant or qualified financial professional may help identify discrepancies. For larger disputes, an independent review may be worthwhile.
Step 4: Submit a formal written complaint to the bank
The first formal step is to complain directly to the bank. Use its official complaints channel, branch or customer service process and retain proof that the complaint was received.
Your letter should contain:
- Your name or registered business name and contact details.
- The bank’s name and the relevant account or facility reference.
- The date and description of each disputed charge.
- The amount in dispute.
- A brief explanation of why you believe the charge is incorrect.
- Supporting documents.
- The specific resolution you want.
- A request for a written response and complaint reference number.
Be clear about the remedy you are requesting. Depending on the evidence, this might include a detailed explanation, correction of an entry, recalculation of interest, reversal of a charge or a refund.
Avoid making unsupported accusations. A factual complaint is easier to investigate and gives the bank a clear issue to address.
Step 5: Keep a record of every communication
Save copies of your complaint, acknowledgement, emails, letters, statements and any response from the bank.
Record the date you submitted the complaint, the complaint reference number and the date by which you expect a response under the applicable complaint-handling process.
The Central Bank of Nigeria’s official guidance states that complaints concerning excess charges and loans are to be resolved by the bank within 30 days. If the complaint remains unresolved after the applicable period, you can consider escalating it to the CBN.
Check the latest official guidance for any changes to the applicable process.
Official reference: CBN — Complaint Lodgement.
Step 6: Escalate the complaint if the bank does not resolve it
If you have first complained to the bank and the issue remains unresolved, you may be able to escalate the matter to the appropriate regulator or consumer-protection body.
Central Bank of Nigeria (CBN)
The CBN provides a complaint process for financial institutions within its regulatory scope. Follow its current instructions and submit evidence that you first complained to the bank.
Visit: CBN Complaint Lodgement.
The CBN also provides official contact information on its Contact Us page.
Federal Competition and Consumer Protection Commission (FCCPC)
The FCCPC provides a consumer complaint-handling process for complaints involving products and services. Its official guidance asks complainants to engage the service provider first and submit relevant supporting documents.
Visit: FCCPC Complaint Handling Procedure.
The FCCPC reported in April 2026 that a Federal High Court had upheld its authority to investigate consumer-protection complaints involving banks. The appropriate route for a particular dispute can depend on its facts, the relief sought and the applicable regulatory framework.
Official reference: FCCPC — Banks Answerable to FCCPC, Court Rules.
When escalating, provide the original complaint, the bank’s response if any, the disputed calculations and evidence of the loss or correction requested. Do not assume that contacting a regulator automatically suspends contractual repayment obligations.
Step 7: Consider professional or legal assistance for complex disputes
Some disputes are straightforward, such as a duplicated debit or a repayment that was not recorded. Others involve complex interest calculations, multiple loan facilities, collateral, guarantees, restructuring agreements or significant sums.
Consider obtaining professional assistance if:
- The bank’s calculations remain difficult to understand.
- The dispute involves a substantial amount.
- You have received a demand letter or legal proceedings have commenced.
- The disagreement involves enforcement against collateral or a guarantee.
- The bank’s records conflict with your accounting records.
- You need advice on the contractual or legal consequences of withholding a disputed payment.
An accountant or financial adviser may help with reconciliation and quantification. A qualified Nigerian lawyer can advise on contractual rights, available remedies and litigation risks.
If a repayment deadline is approaching, seek advice promptly. Do not assume that a complaint alone prevents default interest, collection activity or other consequences under the loan agreement.
What Documents Should You Prepare?
A well-documented complaint is generally easier to investigate than one based only on a verbal disagreement.
Prepare the documents relevant to your case:
- Loan agreement and facility letter.
- Repayment schedule.
- Bank statements covering the disputed period.
- Receipts and proof of repayments.
- Screenshots or transaction alerts where relevant.
- Correspondence about interest rates, fees or changes to the facility.
- Your reconciliation of the disputed amount.
- The complaint submitted to the bank.
- The bank’s response or acknowledgement.
- Evidence supporting the correction, reversal or refund you are requesting.
Keep the originals safely stored and send copies unless an original is specifically required through a verified process.
Security reminder: Never include your banking PIN, password, one-time password (OTP) or other authentication credentials in a complaint. Use official bank and regulator contact details.

What If the Bank’s Charges Are Correct but the Loan Is Difficult to Repay?
Not every loan dispute results from an incorrect calculation. Sometimes the charges are contractually supported, but the business is struggling with cash flow or the overall cost of borrowing.
In that situation, consider discussing a possible restructuring or revised repayment arrangement with the bank. Depending on the lender’s assessment and the terms involved, options may include a revised repayment schedule or another agreed arrangement.
Before accepting a restructuring offer, review the total repayment cost, additional fees, interest treatment, collateral requirements and consequences of missing future payments. A lower monthly instalment does not necessarily mean the loan will cost less overall.
If the dispute concerns both the accuracy of the balance and the affordability of repayment, document the two issues separately. Ask the bank to investigate the disputed figures while you explore any repayment arrangement that may be appropriate.
How Businesses Can Prevent Future Loan-Charge Disputes
Prevention starts before a loan is accepted and continues throughout the repayment period.
Review loan terms before signing
Ensure that the interest rate, fees, repayment dates, default provisions and other material conditions are clearly understood. Ask questions about any unclear or variable terms.
Maintain a dedicated loan file
Store the facility letter, signed agreement, repayment schedule, statements and correspondence in one organised location.
Reconcile loan statements regularly
Compare the bank’s figures with your accounting records at agreed intervals. Investigating a small discrepancy early may be easier than reconstructing several years of transactions.
Record every repayment
Retain transfer confirmations, receipts and other proof of payment. Check that each payment appears correctly in the bank’s records.
Review loan costs during financial reporting
Ensure that loan balances, interest expenses and fees are properly reflected in management accounts and other relevant financial records.
Request explanations promptly
If a new charge appears, ask the bank to explain it rather than allowing the discrepancy to remain unresolved.
These practices help business owners maintain better financial control and make informed borrowing decisions.

The CBN’s published complaint guidance states that complaints relating to excess charges and loans should be resolved within 30 days. Check the official CBN guidance for the current procedure and applicable requirements.
3. Can I complain to the CBN about my bank?
Yes. The CBN provides a complaint process for financial institutions within its regulatory scope. You should first lodge the complaint with the bank and retain evidence of that submission before escalating an unresolved matter.
4. Can I report a bank to the FCCPC?
The FCCPC accepts consumer complaints through its official complaint-handling process. Engage the service provider first and provide relevant documents. Whether the FCCPC or another channel is best suited to your particular issue depends on the circumstances.
5. What evidence do I need to dispute a loan balance?
Useful evidence includes the signed loan agreement, facility letter, repayment schedule, bank statements, repayment receipts, correspondence and a reconciliation showing the specific amount you dispute.

The answer depends on the applicable agreement, disclosure requirements, relevant rules and the circumstances of the charge. Ask the bank to identify the contractual or other lawful basis and explain its calculation. An unexplained charge should be investigated, but it should not automatically be assumed to be unlawful.
7. Should I stop repaying my loan while a complaint is being investigated?
Do not assume that submitting a complaint suspends your repayment obligations. Stopping payments may have contractual and financial consequences. Seek qualified advice about your specific facility, especially if a payment deadline is near or legal action has been threatened.
8. Can a financial consultant help with a bank loan dispute?
A financial consultant or accountant may help review records, reconcile balances, quantify discrepancies and organise supporting evidence. Questions requiring legal interpretation or court action should be referred to a qualified lawyer.
