What it means
Default is not the same as being a few days late. Most lenders define default at a set point of missed payments, commonly 90 days past due, or when a specific term of the loan agreement is breached.
Because the definition is a policy choice, comparing default rates between two lenders is only meaningful once you know each one's cut-off. There are two useful ways to express the rate, and serious lenders track both.
Count-based default rate divides the number of loans in default by the total number of loans, which tells you how widespread the problem is. Value-based default rate divides the balance in default by the total balance outstanding, which tells you how much money is at risk.
The gap between those two numbers is informative. If the value-based rate is much higher than the count-based rate, the defaults are concentrated in larger loans, which usually points at a weakness in underwriting big deals rather than a general decline in borrower quality.
Default rates feed directly into pricing and provisioning. A lender expecting a 3% default rate with a 40% recovery on defaulted balances needs an interest margin that covers roughly 1.8% of expected losses before any contribution to overheads and profit.
Under modern accounting rules, expected losses must be recognised as a provision before the default actually happens, which is why forecasting matters as much as measuring. Businesses outside lending use the same idea on their receivables.
If you sell on credit, the proportion of customer balances that never get paid is your own default rate, and it should influence credit limits, deposits and whether you accept a marginal new customer.
In practice
Real-world examples.
Example
An equipment finance company reports its default rate climbing from 1.8% to 3.1% over three quarters. Investigation shows the increase is concentrated in loans written through one broker channel, which is promptly suspended.
Example
A microfinance lender measures default by value and by count each month. When the value rate spikes while the count rate stays flat, it identifies three large agricultural loans hit by a bad harvest rather than a broad credit problem.
Example
A building materials supplier applies the same thinking to trade credit. It finds that 2.4% of invoiced value is never collected and adds a 3% margin to its list prices for customers on open credit terms.
Think of it
“Default rate shows what percentage of loans go bad-your credit loss frequency.
Formula
Calculation
Default rate by count = (number of loans in default / total number of loans) x 100
Default rate by value = (balance in default / total balance outstanding) x 100
A regional lender ends the quarter with 4,000 outstanding loans, of which 92 are more than 90 days past due and therefore classed as in default. The count-based default rate is 92 / 4,000 x 100 = 2.3%.
Total balances outstanding are $250,000,000 and the balances attached to those 92 defaulted loans total $8,750,000. The value-based default rate is $8,750,000 / $250,000,000 x 100 = 3.5%.
The value rate exceeds the count rate, which tells the credit committee that defaults are clustered in larger loans. If the lender expects to recover 40% of defaulted balances, expected losses are $8,750,000 x 60% = $5,250,000, or 2.1% of the total portfolio.Case study
Seen in the real world.
This is a fictional, illustrative example. Kestrel Point Finance, an invented lender to small construction firms, grew its book from $60,000,000 to $210,000,000 in two years by loosening its minimum trading history from three years to one.
Reported default rates stayed near 1.5% throughout the growth phase, which the board read as proof the strategy was working. What the headline number hid was that a fast-growing book flatters the ratio, because new loans have not had time to go bad and sit in the denominator making the percentage look small.
When lending volumes flattened, the default rate climbed to 6.4% within three quarters. The illustrative lesson is to measure defaults by vintage, grouping loans by when they were written, so that a growing denominator cannot disguise deteriorating credit quality.
Watch out
Common mistakes.
- Treating late payment and default as the same thing. Arrears become default only at the threshold the lender has defined, commonly 90 days past due.
- Measuring the default rate on a fast-growing portfolio without vintage analysis. New loans dilute the ratio and hide problems for a year or more.
- Ignoring recovery rates. A 4% default rate with 80% recovery costs far less than a 2% default rate with no security at all.
Questions
People also ask.
What is a normal default rate?
It depends entirely on the lending type, ranging from well under 1% for secured prime mortgages to double digits for unsecured subprime consumer credit.
Is default the same as write-off?
No, default is the trigger for collection or enforcement, while a write-off is the later accounting decision that the balance is not recoverable.
Should I use count or value for reporting?
Report both, because count shows how many borrowers are struggling and value shows how much capital is exposed.
