What it means
A charge-off happens when a lender concludes that an account is unlikely to be repaid, typically after roughly 180 days of missed payments on a credit card. The balance is written off against the loan loss provision, though the lender usually retains the legal right to pursue the debt or sell it to a collection agency.
The rate matters because it converts individual bad accounts into a single comparable measure of portfolio quality. A card business with a 3% net charge-off rate and one with a 9% rate are running quite different books, and the difference feeds directly into the interest rates and fees each must charge to stay profitable.
Charge-off rates are strongly cyclical and lag the economy. Unemployment rises first, delinquency rates rise a few months later, and charge-offs follow roughly six months after that, which makes early delinquency the more useful leading indicator for management.
Analysts always separate gross and net. Gross charge-offs measure everything written off, while net charge-offs subtract recoveries collected on previously written-off accounts, and net is the figure that reflects the true economic loss.
The rate is also sensitive to portfolio growth, which is a trap for the unwary. A rapidly growing book pushes fresh, not-yet-delinquent balances into the denominator, which mechanically depresses the charge-off rate and can make a deteriorating portfolio look as though it is improving.
For anyone outside a bank, the concept still travels. Any business extending credit to customers can calculate the equivalent measure on its receivables, and comparing that rate across years is one of the fastest ways to see whether credit policy has quietly loosened.
In practice
Real-world examples.
Example
A mid-sized bank reports its quarterly net charge-off rate rising from 4.4% to 6.0% year on year. Management responds by tightening approval criteria for new applicants and reducing credit limits on accounts showing early signs of stress.
Example
An analyst comparing two card issuers notices that the faster-growing one reports a lower charge-off rate. Adjusting for the growth in the denominator, the underlying loss rate on seasoned accounts turns out to be almost identical, which changes the investment conclusion entirely.
Example
A retailer that offers its own store card tracks the same measure on its receivables book. When the rate climbs above 8%, it stops offering instant credit at the till and moves to a short application check instead.
Formula
Calculation
Net charge-off rate = (gross charge-offs - recoveries) / average outstanding balances for the period, annualised by multiplying a quarterly figure by 4
A card issuer reports gross charge-offs of $9,600,000 for a quarter and recoveries of $1,800,000 on previously written-off accounts, so net charge-offs are $9,600,000 - $1,800,000 = $7,800,000. Average outstanding card balances over the quarter were $520,000,000, so the quarterly net charge-off rate is $7,800,000 / $520,000,000 = 0.015, or 1.5%. Annualised, that is 1.5% x 4 = 6.0%, which the issuer would compare against the 5.2% it reported for the same quarter a year earlier to conclude that credit quality has deteriorated.Case study
Seen in the real world.
Fairmount Credit Union is an illustrative and completely fictional lender used to show how a charge-off rate can mislead. Over three years it grew its card book from $180,000,000 to $520,000,000 while its reported annualised net charge-off rate fell from 5.8% to 4.1%, which the board initially read as evidence of better underwriting.
A closer look told a different story. Splitting the portfolio by vintage showed that accounts opened in the growth years were charging off at a materially higher rate than older accounts at the same point in their life, and the headline rate was falling only because the denominator was expanding faster than the losses could season.
In this illustrative example Fairmount slowed new account growth, reintroduced income verification above a certain limit, and began reporting charge-off rates by vintage alongside the headline figure. The general lesson is that a ratio with a fast-moving denominator should never be read on its own.
Watch out
Common mistakes.
- Confusing the charge-off rate with the delinquency rate, when delinquency measures accounts that are behind and charge-offs measure balances already given up on.
- Comparing a gross charge-off rate at one lender with a net rate at another, which overstates the difference because recoveries have been deducted in only one of them.
- Reading a falling charge-off rate at a rapidly growing lender as improving credit quality, when fresh balances in the denominator can mask worsening performance.
Questions
People also ask.
When is a credit card balance charged off?
Typically after around 180 days of non-payment, though the exact trigger depends on the lender's policy and the applicable regulatory guidance.
Does a charge-off mean the borrower no longer owes the money?
No, it is an accounting step by the lender, and the debt usually remains legally owed and may be pursued directly or sold to a collection agency.
How does the charge-off rate affect a card's pricing?
Expected losses are built into the interest rate and fees, so a portfolio running a higher charge-off rate has to price higher to earn the same return.
