How To Account For Inflation In Retirement Planning

couple over 50 working together Inflation is a lurking but serious danger that can destroy your ability to live well in retirement.

If you’re wondering how to account for inflation in retirement planning, the main thing is to simply do it. First, use calculators that factor inflation into the numbers. Next, plan for inflation a little higher than what you think it will be. Finally, plan to own at least some investments that do well during higher inflation. 

In this article, I’ll explain why inflation matters and how to account for inflation in retirement planning. It’s easy to overlook the impact of inflation. That’s because we all tend to focus more on current if not urgent financial needs.

Like most people, my husband and I focus on having the income to pay the bills on a monthly basis without having to dip into investment savings more so than thinking about how we’ll deal with inflation in 20 years.

On the other hand, inflation is an unseen yet very important risk! A good inflation analogy is the effects of aging. When I look in the mirror, I don’t see that I look older than I was the day before, but when I look at a picture from ten or twenty years ago – holy cow! I see the effects of aging!

Inflation is the same way.  

Why Does Inflation Matter?

Inflation matters because you can buy less than you could before with the same amount of money.

Think of how important this is! You think you’ll have a certain amount of money based on retirement planning, and you will. Only it won’t buy anywhere near as much as it did when you were planning for retirement years earlier.

And like aging, you don’t see the depletion of your money from one day to the next, but you sure see it over a few years.

Let’s use an analogy we can all relate to. Imagine you have a grocery budget of $ 200 a week that allows you to easily buy everything you want. You take an envelope to the grocery store with 2 crisp $100 bills in it every week. (Who doesn’t love hundreds?)

Then time travel five years. You take that same $200 to the grocery store, only now, you can only buy 90% of what you could buy just 5 years prior due to inflation based on the recent historical rate of inflation of 2%. And using older past inflation data, it’s even higher than 2% a year!

How Inflation Will Affect Your Retirement

Inflation is especially important in retirement planning for several reasons.

Inflation Salary Increases

When you are employed and receiving an annual salary increase for inflation, which is common, it’s all good. (I fondly remember those annual inflation increases when I was employed.) But after you retire, those COL (cost of living or inflation) salary increases are done.  

Retirement Income and Inflation

If you’re invested in bonds, like many retirees, the income from those bonds is fixed. The income from most bonds is not adjusted for inflation, so the bond income buys less than it did when you bought it. The longer the bond term, the less predictable the inflation effect will be.

Real Return

Here’s the real kicker: If income from a bond is fixed at 3% and inflation is 2% that year, your real return is only 1%. If you pay taxes or some type of wealth management fees, you could have negative income from those bonds!  

How Inflation Affects Stocks

Many of my financial coaching clients are retirees counting on stock dividend income in retirement.

Since the cost of goods and services increases during inflation, some companies will be able to increase dividends to keep up with inflation. But many companies cannot raise their dividends with inflation since they will be paying more for the goods and services which are required to produce the goods they sell.

Companies will also be forced to pay more for the goods and services that they need to run their business (like toilet paper and staff!).

Of course, companies can increase their prices with inflation, but sales can slow if they try to pass the higher costs off to their customers. 

Fortunately, depending on the industry, some companies are less affected by inflation, and some can even benefit from it.

My video below has more that will help account for inflation in retirement planning.



Does Social Security Increase with Inflation?

The good news for retirees is that social security has adjustments for inflation, although they, unfortunately, usually don’t keep up with inflation fully. The increases are commonly called COLA, or Cost of Living Adjustment.  

Average Inflation Rate

Now that you see how inflation can make or break your financial future, let’s look at my favorite investing tools, facts and history, to see how to plan for inflation in retirement.

We know that the cost of goods and services rise by 3% based on long term history, and 2% based on the average from more recent years. But averages are just that.

As you can see from the table below, inflation has been as high as 13.50% during my lifetime (in 1980) and it has also been as low as .1% in recent years.

Here’s the thing to remember. Inflation is not all bad. A little inflation means the economy is growing and thriving.

We just have to account for it in retirement planning, and hope it stays within the range we use to plan!

And it’s hard to plan for retirement with such a large unknown factor.

The chart below shows some of the most extreme deviations from the 3% historical rate of inflation. inflation history chart for retirement planning insights  As you can see, inflation fluctuates a lot.   

Major Causes of Inflation

While it may seem like there’s a conspiracy to sabotage successful retirement planning, inflation actually happens for logical reasons. I have summarized the major causes of inflation below as explained further in an excellent post at

Basically, the causes of inflation relate to either economic growth that is too fast (demand-related) or cost (supply) related factors. (Remember high school economics?)

Here are some examples that demonstrate the effects of inflation. It’s easier to plan for anything you understand, while lack of understanding increases risk.  

Fast Economic Growth/Demand

Here are examples of inflation factors related to fast economic growth.

  • Interest rates are cut. This happens when rates are cut to slow down the economy, so it won’t grow too fast. (Sound familiar?)
  • The money supply is increased. (Also sound familiar?)
  • Wages are higher. This happens when there is low employment and wages have to rise to attract employees.

Supply Related Factors/Supply

Here are some inflation factors related to supply.

  • Higher wages are also a supply related factor.
  • Devaluation occurs. This happens when exports rise, and imports fall.

You can see how inflation has a lot of moving parts that are certainly outside our control as investors.  

Effects of inflation

Let’s look a specific example of how inflation affects something most all of us purchase to bring this a little more into reality.

The cost of going to the movies is a great way to make inflation more real. 

It cost about $5 to buy a movie ticket in 2000. 20 years later it cost $9. That’s an 80% increase in just twenty years.

Note that twenty years is a short time frame to use in most planning for retirement but let’s go with this example. Let’s compare the cost of a movie ticket for someone who is 65 now and wants to go to the movie when they are 85.

Based on history, the movie ticket cost will go from $9 to over $16!

You may be thinking you can just cut out going to the movies. But what if everything you buy costs 80% more 20 years after you retire?

There is a good probability it will be based on history. You can see why it’s so important to account for inflation in retirement planning!  

Retirement Calculator with Inflation

It’s not all doom and gloom. Besides social security increases for inflation, more good news is that most retirement planning calculators have inflation built right into them, which makes it easy to factor inflation into retirement planning.

Some retirement planning calculators have inflation of a certain percent built into the numbers; you can usually find this in the calculator footnotes.

Other retirement calculators allow you to enter your own inflation rate, which can be very tricky since inflation is completely out of our control and therefore impossible to predict with complete accuracy. This is obvious from the inflation rate extremes in the chart above.  

And some services such as Allocate Smartly provide adjustable inflation data for all the investment strategies on their platform to help members plan for retirement.  

How Much Inflation to Plan on in Retirement

The challenge is in knowing how much inflation to plan for in retirement. This is almost as challenging as predicting future investment returns.

We know that inflation is a factor of the economy but then the Federal Reserve takes measures to control inflation.

Fast-growing economies are more prone to have high inflation so the Federal Reserve manipulates interest rates to slow down the economy and avoid extreme inflation. But it is unclear whether the Federal Reserve will always be able to control inflation over the next few decades, especially in such a global economy.

This is why many tactical wealth managers and smart investors add assets that do well during inflation to portfolios at various times.

You can read more about such tactical portfolios in my post All Weather Portfolios Pros and Cons.  

Factors That Affect Retirement Spending

Recent trends can also be a guide as to how much inflation to plan for in retirement. This can be especially valuable if your retirement is coming up within a few years or if you’re already retired.  

Quantitative Easing

The first factor to affect inflation in retirement is quantitative easing. We don’t know the long term consequences of the government printing massive amounts of money to stimulate the economy for years, but we do know it causes inflation. There is no historical precedent for this, which concerns me as a Boomer and (sort of) retiree.

For this reason, it makes sense to use a higher level of inflation in retirement planning; better safe than sorry.  

Health Care Costs

The next factor affecting retirement planning for inflation is health care costs. Rising health care costs call for a higher rate of inflation in retirement planning. One study shows that health care costs were expected to rise 5.3% from 2020 to 2021. (1.) 

An estimated and expected 5% increase in health care costs is what I have seen in numerous studies over the past few years. 

Longer Life Spans

And finally, the longer you live, the more you need to account for inflation in retirement since inflation has a compounding effect over the years. People are living longer and longer because of medical advances.  

How to Protect Against Inflation in Retirement

If inflation concerns you too, there are certain investments you can make that are inflation hedges.

Common investments that help protect against inflation are TIPS bonds, some commodities, and real estate rentals.

Fortunately, TIPS, real estate, and commodities are easy to add to a retirement portfolio through ETFs.

We found owning real estate rentals to be good long term investments as well as good inflation hedges.
