A default rate is the percentage of loans in a portfolio where borrowers have failed to meet payment obligations — typically defined as being 90+ days past due or having received a formal notice of default. Lenders use portfolio default rates to price risk; rising defaults signal worsening credit conditions across an industry or loan type.
Default rate can refer to two distinct concepts. At the portfolio level, it is the percentage of outstanding loan balances (or loan count) where borrowers have defaulted — used by lenders and regulators to assess credit quality. The Federal Reserve publishes delinquency and charge-off rates on loans at commercial banks (https://www.federalreserve.gov/releases/chargeoff/), providing benchmark data for the industry. At the individual loan level, a 'default interest rate' (also called the penalty rate or default APR) is the higher interest rate a lender charges after a borrower triggers a default event — missing payments, breaching a covenant, or filing for bankruptcy. This can significantly increase the cost of an existing loan mid-term if the borrower falls out of compliance. For small business owners, default rate matters as market intelligence: when default rates on a loan type are rising, lenders tighten standards and pricing. The Federal Reserve's Small Business Credit Survey (https://www.fedsmallbusiness.org/survey/2024/report-on-employer-firms) and CFPB supervisory reports track default trends. Understanding default rates by product type helps business owners contextualize the pricing they're offered — higher default risk in a segment drives higher rates for all borrowers in it.
Default typically triggers acceleration (full balance becomes due immediately), default interest rates, potential UCC lien enforcement (seizure and sale of collateral), and personal guarantee calls if applicable. The lender may also charge off the loan and sell it to a collections agency. Delinquency typically hits both business and personal credit reports. Contacting the lender early — before formal default — often leads to better outcomes (forbearance, workout, modification).
Delinquency is being past due on a payment (1+ days); default is a formal contractual event, often triggered at 90+ days past due or by a specific covenant breach, that allows the lender to take enforcement action. All defaults involve delinquency, but not all delinquencies result in formal default.
