Creating a budget for retirement involves estimating your future expenses and income to ensure you can maintain your desired lifestyle. Start by listing your expected sources of income, such as pensions, Social Security, and retirement account withdrawals. Then, estimate your expenses, including housing, healthcare, transportation, food, and leisure activities. Don't forget to account for inflation and potential healthcare costs. Compare your income to your expenses to determine if you're on track, and make adjustments as needed to ensure your budget is sustainable throughout your retirement years. Regularly review and update your budget to reflect changes in your financial situation and lifestyle.
