Retirement changes plenty of financial numbers overnight, from the size of your paycheck to how much money you withdraw from savings each month. One number that does not automatically change when you leave your job, however, is your credit score. Your employment status, retirement date, and income are not factors used to calculate traditional FICO scores, according to FICO. Still, the financial adjustments that often accompany retirement can indirectly affect your credit, sometimes in ways retirees do not anticipate. Understanding what happens to your credit score after retirement can help you protect a strong financial record you may have spent decades building.
