A committed facility can cost money even when it is not drawn. The commitment fee prices the lender’s standby capacity, so treasury should model unused headroom as a real financing cost rather than free insurance.
What commitment fees on undrawn facilities means in practice
A commitment fee is commonly charged on the available but undrawn part of a committed facility, while interest normally applies to amounts actually borrowed. In practice, the finance team should translate that rule into a specific amount, owner and deadline instead of relying on the product name alone.
The fee base can change after drawings, cancellations or expiry of an availability period, so the nominal facility size is not always the amount on which the fee is calculated. The important point for a business is that the operational treatment can change when the contract, currency, legal entity or transaction date changes.
How commitment fees on undrawn facilities changes the commercial position
Borrowers usually pay the fee periodically in arrears, and a facility agreement can contain separate arrangement, agency or security-agent fees alongside it. Treasury should therefore test the exact wording or processor response before assuming the same treatment applies to every transaction.
A low loan margin can still produce a meaningful all-in cost when a large revolving line remains unused for most of the year. That makes traceability essential: the bank record, internal approval and accounting entry should all point back to the same commercial event.
Documents, definitions and data to check
The fees clause and definitions of Available Commitment and Availability Period determine the contractual calculation and should be checked against lender invoices. A simple written control around this point can prevent a later cash, reconciliation or customer-service problem that is much harder to unwind.
Budget models often capture interest on forecast drawings but omit the cost of keeping standby capacity available, understating financing expense in low-utilisation periods. The practical objective is not more paperwork; it is to know what must happen next and who has authority to change the planned outcome.
Failure points and controls
Treasury should maintain a facility schedule with total commitments, drawings, cancellations, fee rates, payment dates and expiry so invoices can be independently reproduced.
Reducing an unnecessary commitment can save fees but also removes emergency liquidity, so the saving should be compared with payroll, working-capital and refinancing resilience.
Worked example: follow the cash and obligations
A company has a £10 million revolving facility, draws £4 million and leaves £6 million undrawn. At a 0.60% annual commitment fee, the unused portion costs about £36,000 a year before day-count and timing adjustments, while interest applies separately to the £4 million drawing.
Use the example as a method, not a universal rule. The article-specific control point is this: Borrowers usually pay the fee periodically in arrears, and a facility agreement can contain separate arrangement, agency or security-agent fees alongside it. The business should reproduce the numbers and timing from its own contract, bank service or processor record before acting.
How to manage commitment fees on undrawn facilities consistently
Implementation check: The fees clause and definitions of Available Commitment and Availability Period determine the contractual calculation and should be checked against lender invoices. The operating owner should convert that requirement into a named approval, a dated record and a reconciliation step so the intended treatment can be reproduced later.
Monitoring check: Treasury should maintain a facility schedule with total commitments, drawings, cancellations, fee rates, payment dates and expiry so invoices can be independently reproduced. Management reporting should show whether this control is working, including unresolved exceptions and material changes rather than only completed transaction volume.
Escalation check: Reducing an unnecessary commitment can save fees but also removes emergency liquidity, so the saving should be compared with payroll, working-capital and refinancing resilience. If the assumption behind that point changes after approval, treasury should stop and reassess the transaction before cash, credit exposure or customer outcome becomes irreversible.
Decision check: A low loan margin can still produce a meaningful all-in cost when a large revolving line remains unused for most of the year. The commercial choice should be made with that trade-off visible, then recorded together with the reason management accepted the remaining risk.
Editorial Verdict
BanksGB’s view starts with the underlying rule: A commitment fee is commonly charged on the available but undrawn part of a committed facility, while interest normally applies to amounts actually borrowed. For commitment fees on undrawn facilities, the business should be able to show how that rule connects to the amount, timing, legal entity and financial outcome of the transaction rather than relying on the product label.
The second test is operational: Budget models often capture interest on forecast drawings but omit the cost of keeping standby capacity available, understating financing expense in low-utilisation periods. A strong commitment fees on undrawn facilities process makes that failure mode visible early, preserves the evidence used for the decision and gives management a realistic escalation route before the position becomes expensive to unwind.
