What it means
Banks and other lenders do not wait for a borrower to default before recognising a loss. Accounting rules require them to estimate expected credit losses in advance and charge that estimate against profit, and that charge is the provision for credit losses.
Two related items are constantly confused. The provision is an income statement expense for the period, while the allowance for credit losses is the cumulative balance sheet reserve that successive provisions build up.
The size of the provision moves with three things: the size and mix of the loan book, the credit quality of the borrowers and the economic outlook. Under expected loss models, lenders must build in forecasts, so a worsening unemployment or property price forecast can raise provisions even when nobody has missed a payment.
Investors watch this line closely because it is a matter of judgement. A lender that under-provides looks more profitable now and takes the pain later, while heavy provisioning in a bad quarter can be released back into profit if conditions improve, which flatters future results.
Lenders rarely calculate a single number for the whole book. They split their lending into segments such as mortgages, credit cards and small business loans, apply a different expected loss rate to each, and then add specific provisions for individually large or troubled exposures.
The figure that reaches the income statement is the sum of all of those pieces. Businesses outside banking meet the same idea under a different name.
Any company selling on credit runs a bad debt expense and an allowance for doubtful accounts, which works identically, just with trade receivables in place of loans.
In practice
Real-world examples
Example 1
A bank with a $2,000,000,000 loan book raises its expected loss rate from 1.0% to 1.4% after its economists cut their growth forecast. The required allowance rises from $20,000,000 to $28,000,000, so with no charge-offs in the quarter the bank books an $8,000,000 provision and reports a sharply lower profit even though no new loan has defaulted.
Example 2
A car finance company notices arrears climbing among borrowers who took loans in one particular quarter. It lifts the provision on that vintage from 3% to 5% of the $60,000,000 advanced, adding $1,200,000 of expense, and tightens approval criteria for new applicants.
Example 3
After two strong years, a lender finds actual losses running below forecast and reduces its required allowance by $4,500,000. The release flows back through the provision line as a credit, lifting pre-tax profit by $4,500,000, and analysts strip it out when judging underlying performance.
Think of it
Imagine running a local fruit shop and letting regular neighbours take fruit home to pay on Friday. Knowing that a couple of people will forget or run out of cash each week, you put aside a few coins from your till daily so you are never caught short when the tally does not add up.
Formula
Calculation
Provision for Credit Losses = Required Ending Allowance - Beginning Allowance + Charge-Offs - Recoveries. A regional lender starts the year with an allowance of $8,000,000 against a $500,000,000 loan book. During the year it writes off $3,000,000 of unrecoverable loans and recovers $500,000 on loans written off previously. Its updated model puts expected lifetime losses at 1.9% of the book, so the required ending allowance is $500,000,000 x 0.019 = $9,500,000. The provision is therefore $9,500,000 - $8,000,000 + $3,000,000 - $500,000 = $4,000,000, and the allowance rolls forward as $8,000,000 - $3,000,000 + $500,000 + $4,000,000 = $9,500,000.Case study
Seen in the real world
Meridian Community Bank, an illustrative fictional lender, held a $400,000,000 loan book weighted heavily towards small hospitality businesses. Its allowance stood at $6,000,000, or 1.5% of loans, when a sharp rise in energy costs began squeezing its borrowers.
The credit team re-ran its models and concluded that expected losses had risen to 2.75% of the book, requiring an allowance of $400,000,000 x 0.0275 = $11,000,000. With charge-offs of $1,000,000 and recoveries of $200,000 during the year, the provision came to $11,000,000 - $6,000,000 + $1,000,000 - $200,000 = $5,800,000, which turned a $9,000,000 pre-provision operating profit into a reported $3,200,000.
The illustrative point is that the bank had not lost $5,800,000 of cash; it had recognised the loss it expected to suffer. Two years later, with hospitality trading recovering, part of that allowance was released and reported profit benefited from a decision taken in the worst quarter.
Watch out
Common mistakes
- Using "provision" and "allowance" interchangeably, when the provision is the expense for the period and the allowance is the running reserve that the provision feeds.
- Reading a large provision as evidence of loans already lost, when it is a forward-looking estimate and a good part of it may never be needed.
- Comparing provision rates between lenders without adjusting for loan mix, since an unsecured credit card book will always carry a higher rate than a residential mortgage book.
Questions
People also ask
Does a provision reduce cash?
No, it is a non-cash accounting entry; cash only moves when a borrower genuinely fails to pay and the lender absorbs the shortfall.
What is a provision release?
When expected losses fall below the existing allowance, the lender reverses part of it, which appears as a negative provision and increases reported profit.
How does this differ from a write-off?
A provision estimates future losses across a portfolio, while a write-off removes one specific loan judged unrecoverable and draws down the allowance already held.
