Retirees need to plan for several expected expenses in retirement including health care costs, utilities, travel, and daily expenses. Health care costs often increase in retirement as retirees experience new illnesses and need expensive treatments. Utilities also tend to rise as retirees spend more time at home. Travel is another significant cost as retirees have more free time. Small daily expenses like dining out can add up over time. Effective financial planning and wealth management are important to address tasks like paying off debt, budgeting, and managing investments.
