When Can I Retire How to Know When to Quit WorkingYou may be physically and mentally ready to retire, but are you financially ready? The answer depends on a number of factors, including your health, your debts, and how well you’ve planned for retirement.

When can I retire?

There really is no “right” answer to this question as there is no magic number or dollar amount that you should have. That may not be the answer you were hoping to hear, but you must weigh the risk of quitting work and no longer receiving a paycheck against the real possibility that you may run out of money. That can be a scary proposition, but it is a real fact that you must take into consideration when you finally decide to retire.

Though you may not be able to escape every risk that you may encounter during your lifetime, there are some steps you can take in planning for retirement that may help reduce the risk of running out of money before you die.

Here are a few things you should consider as you try to decide whether you are financially ready to retire.

The amount of debt you have

Having no mortgage, no credit card debt, and no car payments may help reduce the risk of you running out of money. When living on a fixed income, the less money that is leaving your checking account, the better. The goal of having no debt by the time you retire should be at the top of your list.

Your health

Medical bills can wipe you out. In 2013, NerdWallet Health said rising medical bills were expected to push 1.7 million American households into bankruptcy. Healthcare costs typically increase as you age, and it might be in your best interest to get a second opinion to ensure your future healthcare needs are not overlooked. Consider visiting www.letsmakeaplan.org and sitting down with a Certified Financial Planner™ (CFP) to evaluate all of the options you have to save money for and manage these costs.

The amount of money you have in savings

In addition to the money in your retirement savings accounts, you should have enough money to cover 18 to 24 months of non-discretionary spending. For example, if your monthly non-discretionary spending is $1,000, you should have at least $18,000 to $24,000 in savings, separate from the money that you have in your retirement accounts. When I say savings, I mean that this money needs to be in something that is safe, FDIC insured, and readily available with no penalties if you should need it.

You might ask, why so much? Let’s assume that there is a downturn in the economy that causes your retirement assets to go down in value. With this type of savings established, you would then have somewhere else from where to draw money—with the hope that your retirement accounts might have time to recover their losses.

Consider a practice run

Since practice makes perfect, consider making a “practice run” a year or two prior to retirement. Live only off the income you will be receiving from retirement, instead of your regular salary. To do this, calculate your Social Security benefits and add in any income you’ll receive in the form of a pension or retirement savings withdrawals. See if you can do it for an entire year.

If each month you are cutting it close, or you find that you cannot live on that income, you have two choices. You can either lower your standard of living, or you may have to take a part time job in retirement to supplement your income. It’s better to find that out beforehand rather than six months after you have retired.

When it comes to planning for retirement, I have always said that it is better to plan for the worst and hope for the best and to not leave major decisions to chance. While there are many other risk factors to consider when planning for retirement, if you begin by considering those discussed above, you will be well on your way to understanding your financial readiness.
