Inflation can be easy to overlook when markets are performing well, and retirement income appears sufficient. But for someone approaching or already living in retirement, rising prices can create a challenge that extends far beyond the next grocery bill or utility statement: purchasing power.

A retirement plan may look comfortable on paper today and still face pressure if the cost of living rises faster than expected over the next 10, 20, or 30 years.

That is why inflation deserves more than a passing mention in a retirement plan. It deserves to be stress-tested.

Recently, the Consumer Price Index (CPI) was up 3.4% over the previous 12 months, while core CPI—which excludes food and energy—was up 2.5%. Energy prices were particularly notable, rising 14.7% over the year. (Bureau of Labor Statistics)

The question for retirees isn’t necessarily whether inflation will spike again. No one can reliably predict the timing or magnitude of future inflation.

The better question is: Would your retirement plan still work if it did?

Inflation Doesn’t Have to Be Extreme to Matter

When people think about inflation risk, they often picture a repeat of the unusually high inflation experienced in recent years.

But retirement planning doesn’t require an extreme scenario to illustrate the potential impact.

Consider someone who spends $100,000 per year in retirement.

If inflation averaged 2.5% annually, maintaining the same purchasing power would require roughly $128,000 after 10 years and approximately $164,000 after 20 years.

At 4% inflation, those figures would be approximately $148,000 after 10 years and $219,000 after 20 years.

That’s the compounding effect of inflation.

The issue isn’t simply that individual expenses become more expensive. It’s that the amount of income required to maintain a similar lifestyle can increase substantially over a long retirement.

For retirees with significant assets, this doesn’t necessarily mean there is an immediate problem. It does mean that a retirement plan should account for changing expenses rather than assuming today’s spending needs will remain constant.

And the longer retirement lasts, the more important that distinction becomes.

Why Inflation Can Be Particularly Challenging in Retirement

During your working years, inflation can sometimes be offset by rising wages.

Retirement is different.

Once you stop receiving a paycheck, you generally don’t have an employer increasing your salary to help compensate for higher prices.

Instead, your retirement income may come from a combination of:

• Social Security
• Pension income
• Retirement accounts
• Investment portfolios
• Business or real estate income
• Other personal assets

Some sources may have built-in inflation adjustments. Others may not.

That creates an important planning consideration: How does each source of retirement income behave when prices rise?

Social Security, for example, includes an annual cost-of-living adjustment (COLA). For 2026, Social Security benefits increased by 2.8%. (Social Security Administration)

However, a COLA isn’t necessarily designed to perfectly match every retiree’s personal spending pattern.

Healthcare, housing, insurance, travel, and other expenses can change at different rates than the overall CPI.

In other words, the inflation rate reported in the headlines isn’t necessarily the inflation rate experienced by your household.

That’s one reason retirement planning should focus on your spending needs and your income sources, not simply one inflation number.

The Difference Between Nominal Dollars and Real Purchasing Power

One of the most important concepts in retirement planning is the difference between nominal dollars and real purchasing power.

If your portfolio grows by 5% in a year when inflation is 3%, your nominal return is 5%, but your purchasing power has increased by less than 5%.

Taxes and investment costs may reduce the amount further.

This is why looking only at an investment’s stated return can provide an incomplete picture.

Imagine a retiree earns a 5% return on an investment while inflation is running at 4%. At first glance, a 5% return may sound attractive.

But the difference between the return and inflation is much smaller than the headline number suggests—and taxes, fees, and withdrawals can further affect the outcome.

For retirement planning, the goal isn’t simply to pursue a particular return.

It’s to understand whether the overall strategy has a reasonable framework for supporting spending needs over time while accounting for market volatility, taxes, longevity, and inflation.

Inflation Can Affect More Than Your Expenses

Inflation doesn’t only affect the spending side of the retirement equation.

It can also affect the investment side.

Different types of investments can respond differently to changing inflation and interest-rate environments. Stocks, bonds, cash, and inflation-sensitive assets each have different characteristics, risks, and potential roles in a portfolio.

For example, traditional fixed-rate bonds can face price pressure when interest rates rise. At the same time, bonds can play an important role in portfolio diversification and income planning.

This is why responding to inflation isn’t necessarily as simple as moving money into one particular asset class.

A retirement portfolio should be evaluated as a whole.

The right balance depends on factors such as your time horizon, income needs, risk tolerance, tax situation, and broader financial objectives.

Don’t Build a Retirement Plan Around One Inflation Assumption

One of the biggest mistakes in long-term planning is treating a single inflation assumption as a certainty.

A retirement projection might assume inflation averages 2% or 3% for decades.

That can be useful for modeling purposes—but it shouldn’t create a false sense of precision.

Actual inflation won’t necessarily move in a straight line.

You could experience:

• Several years of relatively low inflation
• A temporary inflation spike
• Periods of higher energy prices
• Changes in housing costs
• Unexpected increases in healthcare expenses
• Periods of disinflation or even declining prices in certain categories

The Federal Reserve’s June 2026 projections and subsequent July meeting materials continued to reflect uncertainty around the inflation outlook. The Fed has also noted that inflation remains elevated relative to its 2% goal, while its staff outlook anticipated inflation declining over time. (Federal Reserve)

That uncertainty is exactly why retirement planning should not depend on getting an economic forecast exactly right.

A resilient plan is designed to adapt.

What Would an Inflation Stress Test Look Like?

If you’re approaching retirement, one useful exercise is to ask what happens to your plan under several different scenarios.

For example:

Scenario 1: Inflation stays relatively moderate

What happens if inflation remains close to the levels you’ve incorporated into your retirement projections?

Does your projected income adequately cover your expenses?

Scenario 2: Inflation runs higher for several years

What if inflation rises meaningfully above your baseline assumption for five years?

Would you need to reduce spending?

Would you have enough flexibility in your portfolio and other income sources?

Scenario 3: Inflation affects certain expenses disproportionately

What happens if healthcare, insurance or housing costs rise faster than the overall inflation rate?

Would your retirement income still provide enough flexibility?

Scenario 4: Inflation rises while markets are volatile

This scenario deserves particular attention.

A period of elevated inflation could potentially coincide with market volatility. If you’re withdrawing from your portfolio during a downturn, the combination can create additional pressure on retirement assets.

This is one reason retirement planning involves more than determining a target portfolio value.

The timing and structure of withdrawals matter, too.

Sequence of Returns and Inflation: A Potential Double Challenge

Market volatility early in retirement can have a meaningful impact on a portfolio because withdrawals are occurring at the same time investments are experiencing gains or losses.

Now add inflation.

If expenses increase while portfolio values are declining, a retiree may need to withdraw more money at an unfavorable time.

That’s why retirement income planning should consider both market risk and purchasing-power risk.

A comprehensive strategy may address questions such as:

• How much income do you need from your portfolio?
• Which income sources are relatively predictable?
• How much liquidity do you maintain?
• How might withdrawals change during different market conditions?
• How much portfolio growth may be needed over time?
• What expenses are likely to increase with inflation?
• How much flexibility exists in discretionary spending?

There isn’t one universal answer to these questions.

The goal is to understand how the pieces work together.

What About Inflation-Protected Investments?

Some investments are specifically designed to provide a degree of protection against inflation.

Treasury Inflation-Protected Securities, or TIPS, are one example. Their principal is adjusted based on changes in the Consumer Price Index, and interest payments are based on the inflation-adjusted principal. At maturity, investors receive the inflation-adjusted principal or the original principal, whichever is greater, subject to the security’s terms. (TFX)

TIPS can therefore play a role in discussions about inflation risk.

But that doesn’t mean every retiree should automatically add TIPS—or any other particular investment—to a portfolio.

Every investment has tradeoffs.

The appropriate role of any asset depends on the broader portfolio, objectives, time horizon, liquidity needs, tax considerations, and risk tolerance.

Inflation protection is one consideration among many.

Don’t Forget About Taxes

Inflation planning also intersects with taxes.

A retirement portfolio isn’t simply a pool of money available for spending. Depending on the account type, withdrawals may have different tax consequences.

For example, distributions from traditional retirement accounts can generally be taxable as ordinary income, while qualified Roth distributions can receive different tax treatment under applicable rules.

Required minimum distributions, Social Security taxation, capital gains, and other sources of taxable income can also influence a retirement income strategy.

That’s why an increase in spending needs doesn’t necessarily translate directly into an equal increase in the amount you should withdraw.

The tax implications matter, too.

For high-net-worth households in particular, retirement planning may involve coordinating investments, income sources, tax planning, and estate considerations rather than treating each issue separately.

Inflation Planning Isn’t About Predicting the Future

It’s tempting to look at current economic data and ask:

“Where is inflation going next?”

But retirement planning doesn’t require an accurate prediction of the next CPI report.

In fact, trying to time a portfolio around short-term economic forecasts can create its own risks.

Instead, the more useful question is:

“What happens to my plan if my assumptions are wrong?”

That’s a fundamentally different approach.

Rather than betting your retirement on a specific inflation forecast, you can build a plan that considers a range of possible outcomes.

That might mean reviewing:

• Your current and projected spending
• Essential versus discretionary expenses
• Guaranteed or relatively predictable income sources
• Portfolio diversification
• Withdrawal strategies
• Cash and liquidity reserves
• Tax considerations
• Social Security timing
• Long-term healthcare expenses
• Estate and legacy objectives

The goal is not to eliminate uncertainty.

It’s to understand it.

What Can You Do to Help Protect Your Retirement Plan From Inflation?

You can’t control inflation—and you can’t know exactly when the next inflation spike will occur. But you can take steps to help make your retirement plan more resilient to changing prices.

1. Revisit your retirement spending assumptions.

Start with what you actually spend today. Then separate essential expenses—such as housing, food, insurance, and healthcare—from discretionary expenses such as travel, entertainment, and hobbies.

This distinction can help you understand which expenses your retirement income needs to cover regardless of economic conditions and where you may have flexibility if prices rise.

2. Stress-test your retirement income plan.

Don’t look at your retirement projection using only one inflation assumption. Consider how your plan might perform if inflation runs higher than expected for several years.

Ask: Would I still be able to cover my essential expenses? Would I need to make changes to my withdrawals or discretionary spending?

Stress-testing can help reveal potential pressure points before they become problems.

3. Review your portfolio’s diversification.

Inflation can affect different investments in different ways. That’s one reason diversification and appropriate asset allocation can be important components of a long-term investment strategy. The SEC notes that an appropriate asset allocation depends on factors including your time horizon and risk tolerance, while diversification can help manage investment risk.

That doesn’t mean there’s a single “inflation-proof” investment or that you should make dramatic portfolio changes whenever inflation rises. Instead, your portfolio should be evaluated in the context of your overall retirement objectives, risk tolerance, and income needs.

4. Consider the role of inflation-sensitive assets.

Certain investments are designed, in part, to respond differently to inflationary environments. Treasury Inflation-Protected Securities (TIPS), for example, are specifically structured to adjust principal based on changes in the Consumer Price Index.

Other investments may also have characteristics that can help provide some potential protection against rising prices—but each comes with its own risks and tradeoffs.

The goal isn’t to find one investment that “beats inflation.” It’s to understand how different components of your portfolio may help contribute to your overall retirement strategy.

5. Build flexibility into your withdrawals.

A retirement income strategy doesn’t necessarily have to be rigid.

If inflation rises unexpectedly, having some flexibility around discretionary spending and portfolio withdrawals may help give your plan more room to adapt.

This can be particularly important during periods when investment markets are also experiencing volatility. Taking larger withdrawals from a declining portfolio can put additional pressure on a retirement strategy, which is why withdrawal planning deserves attention alongside investment selection.

6. Review your income sources.

Take a closer look at where your retirement income will come from and how each source may respond to inflation.

Social Security, pensions, investment accounts, and other income sources can have very different characteristics. Understanding how those sources work together can help you identify potential gaps between your income and future spending needs.

7. Review your plan regularly—not just when inflation makes headlines.

Inflation doesn’t need to spike before you review your retirement plan.

Your expenses, portfolio, tax situation, income needs, and goals can all change over time. A regular review can help ensure your assumptions remain reasonable and your strategy continues to reflect your circumstances.

A Retirement Plan Should Evolve With Your Life

Your retirement plan shouldn’t be something you create once and put in a drawer.

• Your spending may change.
• Your portfolio may change.
• Tax laws may change.
• Interest rates may change.
• Inflation may change.
• Your goals may change.

That means retirement planning should be an ongoing process.

An annual review can help provide an opportunity to revisit assumptions and determine whether your strategy still aligns with your objectives.

For someone nearing retirement, that review may be especially important.

The closer you are to relying on your portfolio for income, the less useful it is to think about retirement solely in terms of accumulation.

The conversation becomes increasingly focused on income, sustainability, risk, and flexibility.

The Bottom Line: Plan for Purchasing Power, Not Just a Dollar Amount

A retirement plan can look successful if you focus solely on the account balance.

But a dollar today won’t necessarily buy what a dollar buys 10, 20, or 30 years from now.

That’s the fundamental challenge inflation presents.

The objective isn’t to predict whether inflation will rise, fall, or remain elevated.

It’s to ask whether your retirement strategy has enough flexibility to accommodate changing costs and changing economic conditions.

With inflation still above the Federal Reserve’s long-term 2% objective and energy prices showing significant year-over-year increases as of the latest available CPI report, purchasing-power risk remains relevant for retirement planning. (Bureau of Labor Statistics)

Your retirement plan should be built for the retirement you want—not just the economy you have today.

If you haven’t reviewed how inflation could affect your retirement income, now may be a good time to revisit your assumptions.
