Charge-offs and credit losses tend to fluctuate according to the health of the economy. For example, they're more likely to decline in a bull market and expand in a bear market.
For borrowers, charge-offs have a different context. A charge-off generally means that your debt has been passed along to a debt collector and will be reported to credit agencies, negatively affecting your credit score.
If you are notified of a charge-off, you're still legally obligated to pay the debt. The time period for the lender to charge off the debt generally ranges between 120 and 180 days after it's delinquent, although lenders typically make multiple efforts to collect it from you before passing it along to a debt collector.
