Dear Liz: After many years of unemployment, I finally got a full-time position. It is a state job with a pension. How much do I need to save for retirement? Can I focus on paying off debt and saving for college, and trust I will be OK in retirement?

Answer: Your long stint of unemployment should have taught you that no job, and no plan for your life, is guaranteed.

You may have to work for the state for years to become “vested” in the plan, or eligible for a retirement check. In order to actually retire, you typically have to stay employed by the state for a decade or more. Even then, your check in retirement may not replace a big chunk of your salary. Traditional defined benefit pensions tend to offer the highest benefits to those who work for the system for decades.

A lot can happen while you’re waiting for your pension to build. You could get fired or laid off or suffer a disability that limits your ability to work. The pension plan itself could change.

If your employer doesn’t pay into the Social Security system, that adds another layer of uncertainty to your future. You could wind up without a pension, or only a small pension, and less Social Security than you might have had with a job that did pay Social Security taxes.

That’s why it’s essential to save for retirement even with the prospect of a good pension. You may be offered a tax-deferred workplace plan, or you can save on your own through IRAs or taxable accounts.
