If retirement is not mandatory, the first question to answer before you sell your practice is, “How do I know if I have enough money to retire?” This column outlines the information you must gather in order to determine your choices on transitioning your practice.

Let’s examine the protocol for planning retirement.

Determine your expenses for one year.

Calculate on a monthly basis what you spend on food, housing, gas, utilities, medical expenses, medical insurance, car insurance, entertainment, clothing, gifts, golf, travel, etc. (use last year’s checkbook and credit card bills as aids).

Include income tax payments and replacement of major items such as an auto or a new roof. (For example, if you pay \$35,000 for a car and keep it for seven years, add \$5,000 per year for auto; if a roof costs \$6,000 and is replaced every 15 years, add \$400 a year for a roof.). Be realistic about how you spend money. Most people travel more in retirement.

Total all of the above expenses to determine your yearly financial needs.

Determine your retirement income for one year.

After retirement, do you plan to live strictly off of the income from your investments (leaving the principle for emergencies or for your children) or, do you plan to live on a combination of the income and principle of your investments (hoping you take your last breath as you spend your last dime)?

If the answer is “A — Live on the income and leave the principle,” add the following:

• Yearly income from your present taxable investments.
• Income from IRAs and Social Security.
• Income from money invested from the practice sale.
• For example, let’s say you plan to sell your practice for \$300,000. You will pay a minimum of 15 percent in taxes, leaving \$255,000 to invest. Invested at 5 percent interest, your yearly income from this investment will be \$12,750.
• The total of 1 + 2 + 3 = yearly income.

If the answer is “B — Live on income and principle,” your CPA or CFP will calculate your expected yearly income based on your life expectancy. He or she will calculate your future income from Social Security, current taxable investments, IRAs, and the investment of the proceeds from the practice sale (after taxes). Use your CPA’s figure as your yearly income.
