Delinquency rate measures past-due or nonaccrual loans relative to a defined portfolio, using account counts or balances at a reporting date.
The delinquency rate measures loans or leases classified as delinquent relative to a defined portfolio at a reporting date. It can be calculated by account count or dollar balance and may cover all past-due accounts, a threshold such as 30+ or 90+ days past due, or both past-due and nonaccrual loans.
The label is not complete without the aging threshold, unit, denominator, and nonaccrual treatment. A lender’s operational 1+ day delinquency rate and the Federal Reserve’s commercial-bank delinquency series do not measure exactly the same population.
30-59, 60-89, and 90+ days show severity better than one total rate.For a balance-based rate:
For a count-based rate:
The numerator and denominator must cover the same product, entity, and reporting date. If nonaccrual loans are included in the numerator, the methodology should say so.
Assume a lender has 10,000 loans with a total balance of $200 million at quarter-end. Its delinquent balances are:
| Status | Balance |
|---|---|
| 30-59 days past due and accruing | $2.4 million |
| 60-89 days past due and accruing | $0.9 million |
| 90+ days past due and accruing | $0.4 million |
| Nonaccrual | $1.3 million |
| Total delinquent under this methodology | $5.0 million |
The total balance-based delinquency rate is:
The 60+ rate, including nonaccrual loans, is:
The severe 90+ and nonaccrual rate is:
Suppose 300 of the 10,000 accounts are delinquent. The count rate is 3.00%, above the 2.50% balance rate. That indicates the delinquent accounts are smaller than the average portfolio account. Neither rate is inherently better; they answer different questions.
| Bucket | Typical interpretation | Main caution |
|---|---|---|
| 1-29 days | Very early payment delay | Can be operational, temporary, or affected by due-date processing |
| 30-59 days | Established early delinquency | Some accounts still cure without major loss |
| 60-89 days | More persistent stress | Cure probability may be lower, but product behavior differs |
| 90+ days | Severe delinquency | May overlap with default or nonaccrual definitions |
| Nonaccrual | Interest recognition restricted under applicable policy | Not every nonaccrual loan is reported in the same past-due bucket |
These labels are conventions, not universal legal rules. A monthly installment can be reported using the oldest unpaid contractual payment, the number of payments missed, or another documented aging method. Credit cards, mortgages, commercial loans, and leases can follow different reporting rules.
The delinquency rate is normally a snapshot: it asks what portion of the portfolio is delinquent now. It does not show how many accounts entered, cured, or advanced between buckets.
For movement analysis, lenders also use:
Two portfolios can report the same 30+ snapshot rate while having very different flows. One may have many new delinquencies and many cures; the other may contain a stable group of long-running problem loans.
The Federal Reserve’s commercial-bank data define delinquent loans and leases as those at least 30 days past due and still accruing interest plus those in nonaccrual status. The published delinquency rate divides delinquent balances in a loan category by total loans outstanding in that category.
That convention supports consistent analysis of the published series. It should not be imposed on every lender dashboard, consumer-credit product, contract, country, or accounting framework. Always use the definition supplied with the data.
| Metric | Usually measures | Timing |
|---|---|---|
| Delinquency rate | Past-due or nonaccrual stock at a date | Early through severe stress |
| Default Rate | New or existing defaults under a stated definition | Serious contractual or risk event |
| Charge-Off Rate | Gross or net realized-loss flow relative to loans | Later recognition outcome |
Not every delinquent loan defaults, and not every default produces the same loss. Collateral, guarantees, seniority, modification, collection cost, and recovery timing affect the path from delinquency to charge-off.
90+ loan is a total loss.Delinquency rates are backward-looking and can be affected by servicing systems, due-date conventions, payment processing, modifications, natural-disaster relief, loan sales, and policy changes. A low current rate can coexist with weak underwriting in a young portfolio that has not seasoned. A broad average can also conceal severe deterioration in one vintage or borrower segment.
