There are two types of Keogh plans available: profit-sharing plans and defined benefit plans. A Keogh defined benefit plan is set up to receive a specific benefit at retirement. The contribution must be figured by an actuary. The exact amount depends on your desired benefit, income, anticipated investment returns, and years until retirement. Administrative costs run a couple thousand dollars a year and once the defined benefit plan is established, the employer must contribute to it each year.
Defined benefit Keogh plans and its associated costs may be beneficial if you earn a lot of money and are approaching retirement; otherwise, an IRA, SEP, Solo 401 (k), or profit sharing Keogh makes more sense.
