Figuring Out When You Can Retire

The word "retirement" means different things to different people. Some people look at it as the year in which they will quit working full time and will take on a part time job while relaxing a lot more. It can also mean the year in which people take their social security and/or pension.

To keep it simple I want to look at a couple that is trying to figure out when they can stop working altogether. Let's say this couple is 50 years old. Their goal is to retire when they are both 62, but they want to make sure they have a very good chance of never running out of money in retirement.

Let's assume they currently have $500,000 saved. Half of their money is in taxable accounts and half is in IRAs. I also assumed that 70% of their money is in value stocks and the rest is in medium-term treasury bonds. They save $10,000 a year, they will receive a combined $40,000 in social security payments when they reach age 67, and their plan is to spend $50,000 a year in retirement. I have assumed 2.5% inflation per year, 6% returns on equities per year, and 2% returns on their treasury bonds per year. Here are my assumptions summarized:

Inflation (CPI)


Current Age of Both People


Age Of Retirement


Age When Both People Have Passed Away


Social Security at age 67 (combined)

$40,000 per year

Average Savings Rate

$10,000 per year

Recurring Annual Expenses in Retirement


Investment Mix

70% U.S. Value Stocks, 30% Medium Term Treasuries

Investment Location

50% in taxable accounts, 50% in IRAs

Return Assumption Value Stocks

6% per year

Standard Deviation Value Stocks


Return Assumption Treasuries

2% per year

Standard Deviation Treasuries


I inputted all of these assumptions into our retirement planner and found that, in the static base case, this couple would have about $700,000 when they retire and that they will never run out of money. However, it is best to look at the probability of never running out of money since this takes into account dynamic investment returns over time. So I ran a Monte Carlo analysis in our software. This entails generating one thousand simulations, shocking investment returns every year based on the historical volatility levels of each investment type. Doing this, I found that they only have a 61% probability of never running out of money.

So what if this couple postpones retirement to age 64? This increases their chances of never running out of money by 7%, giving them a 68% probability of success.

Let’s say this couple is not comfortable with this probability and they would like to see it above 80%. What can they do to get there?

Part of the problem this couple has with attempting to retire at age 62 is that their income simply isn’t coming close to meeting their expenses. Recall that 30% of their funds are in treasury bonds earning 2% per year. But what if we were to move them into high quality dividend paying stocks that generate closer to 4% per year in dividend returns (which includes dividend yield and dividend growth) and 2% in price appreciation? A few of my favorite dividend payers for retirement portfolios that have a dividend yield of 2.5% or higher are Johnson & Johnson (JNJ), Intel (INTC), Merck (MRK), AT&T (T), Eli Lilly (LLY), and Exxon (XOM).

 I swapped all of their treasuries for the above stocks and equally weighted them. I also assumed that these dividend payers are less volatile than an equity index, which has been shown to be true given their relatively steady dividend contributions to total returns. I assumed a standard deviation (volatility) of 12% for the dividend paying stocks.

With all of this extra dividend income helping to cover expenses, the probability of them never running out of money, even if they retire at age 62, is 87%. This is a very comfortable spot to be in.

Of course, moving their funds into equities is riskier than keeping it in shorter term treasuries. But the goal is to find companies with a history of paying strong and growing dividends over time. If we can find these types of companies, price fluctuations are not nearly as important as that dividend check coming through each quarter.

I usually get at least one person asking the question, "But what if I don't have $500,000 saved already!" Let's look at an example where a couple is 50 years old, but only has $250,000 saved. The question is, when can they retire and have a probability of success of at least 80% (assuming they move to the dividend-growth strategy).

I ran these numbers and found that this couple would have to wait until age 67 to retire comfortably (with a probability of success of 80%).

Each person and couple has a different situation and might need to change a variety of things in order to retire earlier. But it is usually impossible to tell whether or not you can retire when you want until you sit down and actually run through the numbers. At that point you can begin running interesting scenarios that will tell you what you need to do to get to your goals.
