Find Out in Five Minutes if You Have Enough to Retire
It's a common question these days: Can I afford to retire? To calculate a ballpark answer, here's a quick and easy exercise.


My 6-year-old daughter loves working around the house to earn money. Perhaps we’re a bit early with these lessons. Nevertheless, when she earns money, it goes into an envelope with the words “baby doll” on it. One thing that kids understand that adults seem to have forgotten is that money itself has no intrinsic value; it is what it affords us that actually matters.
As adults, we tend to forget this until we face imminent transitions, such as buying a home, sending our kids to college and the big one: retirement. When we start nearing retirement, we start to question whether we can afford to do it.
In the next few paragraphs, I’m going to teach you a five-minute exercise you can do to see if you have (about) enough to retire. Note that there are lots of rules of thumb and assumptions in this exercise that may not apply to you. If you want this to be much more complicated, it can, and probably should be, if you’re going to decide to walk away from work. But if you just want a spot check to see where you stand, this should do the job.

1. Tally up your expenses
If you make more than you spend, you have earned the luxury of not having to budget. Budgeting is not an exercise that people enjoy. Unlike your working years, budgeting in retirement is not optional. Pull out too little money and you’ve unintentionally paid for your kids’ country club memberships. Pull out too much and you’ll run out.

At age 26, I earned my CERTIFIED FINANCIAL PLANNER™ certification. I also hold the IRS Enrolled Agent license, which allows for a unique approach to planning that can be beneficial to retirees and those selling their businesses, who are eager to minimize lifetime taxes and maximize income.
Here’s a simple trick: Look at two years of annual statements from your bank accounts. Divide the total debits by 24. That’s it. This is an accurate portrayal of your monthly expenses. This should encompass everything except what you pay for before it hits your bank account (taxes, health insurance premiums, group life insurance, etc.).
2. Gross up the monthly amount to account for taxes
It’s likely that the majority of your retirement savings will be taxed in some shape or form. Roth IRAs and municipal bonds are notable exceptions.
If your monthly expenses are $10,000 and your effective tax rate (how many cents you lose on the dollar to taxes) is 20%, divide $10,000 by 0.8 to arrive at $12,500 per month. That’s the gross amount you’ll need every month to end up with $10,000 in your bank account to cover your expenses.
3. Subtract Social Security and other fixed income streams
Let’s say that you and your spouse are receiving $5,000 per month from Social Security. This leaves a gap of $7,500 per month ($12,500 minus $5,000) that needs to come from somewhere else.
If you have a pension or annuity, subtract those figures, too. Let’s say for this example there is a pension of $2,000 per month. Therefore, we need to take $5,500 per month from our investments.
4. Divide by 4%
The next, most important question is how much we need saved up in our investment account in order to be able to pull out that amount each month. The “4% rule” has gotten more widespread attention in recent years, with folks wondering if it still works. There are lots of different retirement income strategies that, in my opinion, are more effective for withdrawing your savings. However, I have found nothing better than the 4% rule to quickly determine whether you are in the range of having enough money saved.
Using the numbers from step three, you’ll have to multiply $5,500 by 12 to get your annual shortfall amount: $66,000. Divide $66,000 by 0.04 (4%), and you’ll get $1.65 million. If this example is your exact situation and you have more than $1.65 million, you probably have enough. If you have much less, you’ll need to work longer, spend less or find some other way to stretch your savings.
5. Verify for your situation
As I have repeatedly pointed out, this is just a back-of-the-envelope framework. Here are a few of the major things that could throw it off:
- If you retire before you claim Social Security. In that situation, there is a gap between the income streams and the paychecks, which would cause a higher-than-4% withdrawal rate in the early years.
- If you need long-term care late in life. Needing long-term care is a risk for almost everyone. It can be offset by insurance or by earmarked investments. Either way, it will create a need for more money.
- If you have a really low risk tolerance. Financial adviser Bill Bengen, who created the 4% framework, assumed a 50% stock/50% fixed income portfolio. If you’re not willing to have 50% of your money in stocks, you’ll likely have to withdraw less.
A financial plan is your road map. It will tell you if you have enough, (mostly) confirm that it will last and point out any other gaps in your situation. It’s imperfect and life is always changing, so I would not walk away without a plan to confirm the numbers.
