Why Retirees Need a Budget, According to a New Retiree

As a longtime personal finance writer, I've lost track of the number of stories I've written about the importance of creating a budget. So now it's time for a confession: When I was working, I never really had one.

Instead, I took an approach that I suspect is pretty common. If I had money left at the end of the month — and was able to pay off my credit card balance — I figured I was doing okay. And like millions of working Americans, I had contributions to my 401(k) plan automatically deducted from my paycheck.

All of that changed when I retired. Without a regular paycheck, I can no longer use this back-of-the-napkin strategy to calculate how much I can afford to spend each month. Like a lot of retirees, I have a long list of things I'd like to do — from digitizing hundreds of family photos to touring Ireland — and most of them cost money, so having a plan is essential.

For many retirees, this transition is so discombobulating that they withdraw less from their savings than they can reasonably afford to spend based on the amount they've saved and their life expectancies. A 2018 survey by the Employee Benefit Research Institute found that retirees with $500,000 or more in savings spend less than 12% of their assets within the first 20 years.

For retirees who are struggling to get by, this may seem like a nice problem to have. But underspending in retirement is not without its downsides. While you may not run out of money, you could forgo activities that enhance your quality of life — and even help prevent cognitive decline.

Methods to manage your income in retirement

One strategy to get around this roadblock is to buy a single-premium income annuity, or SPIA. After you make a lump-sum investment, an SPIA provides a monthly check, for either a set period or the rest of your life.

By annuitizing your monthly non-discretionary expenses, such as groceries and utilities, you may feel more comfortable withdrawing money from your savings to cover the fun stuff. The drawback is that in exchange for guaranteed income, you usually can't get your investment back.

An alternative that gives you more flexibility is to create a paycheck by having a set amount of money withdrawn from your savings every month. You can adjust the amount withdrawn as your spending changes.

Another strategy is known as the bucket system. With this method, you divide your savings into three buckets: One for money you'll need for the next two years, another for money you'll need in years three through 10, and a third for funds you'll need in the distant future or for your heirs.

Money in the first bucket is placed in low-risk, easily accessible bank savings accounts or money market funds. The second bucket contains income-generating certificates of deposit and bonds, and the third is in stocks and other long-term investments that offer higher returns. This method protects you from having to withdraw money from stocks and mutual funds during market downturns.

For the bucket strategy to work, though, you need to get a handle on your expenses. Otherwise, you risk putting too much — or too little — in your first bucket.

Since I retired, I've used Google Sheets to track our monthly household spending, with categories for expenses such as food, health care, taxes and subscriptions. (Our 11-year-old Border Collie, Morgan, gets a category, too.) Scrutinizing our expenses has helped me reduce some of our costs.

I downgraded our Netflix subscription to the model that includes ads, which will save us about $10 a month, and I have become a big fan of digital coupons. Cutting back on everyday expenses has made it easier to plan for the big ones — like a trip to Ireland. Sláinte!
