Certificates of deposit, or CDs, have long been a staple in conservative retirement portfolios. They promise safety, predictable returns, and an easy set-it-and-forget-it approach for those who don’t want to weather stock market volatility. But in today’s high-inflation environment, many retirees are wondering: Is locking money into a CD still a wise move, or are you effectively losing purchasing power while thinking you’re playing it safe?

The answer isn’t as simple as yes or no. CDs can still serve a purpose, but the value they provide depends on how inflation, interest rates, and your personal financial situation interact. In this blog, we’ll unpack the risks, benefits, and hidden considerations you need to weigh before putting your money into a CD in 2025 and beyond.

Is It Still Worth Investing in CDs With Today’s Inflation?

Why CDs Have Been a Go-To for Retirees

For decades, CDs have been the poster child for safety in savings. You deposit a set amount of money with a bank or credit union, commit to leaving it untouched for a specified term, and in return, you get a guaranteed interest rate. Unlike stocks, your principal is not at risk—FDIC or NCUA insurance protects deposits up to the standard limit, currently $250,000 per depositor per institution.

In times when inflation was low and interest rates were competitive, CDs provided retirees with predictable, low-stress income. They were a way to earn more than a standard savings account without exposure to market swings. For risk-averse savers, CDs felt like a safe harbor.

How Inflation Changes the Math

Here’s the challenge: inflation erodes purchasing power. If the inflation rate is higher than your CD’s interest rate, the “real return” on your investment becomes negative.

For example, if you buy a 3-year CD at 4% interest but inflation runs at 5%, you are effectively losing 1% in real terms each year. That’s before considering taxes on the interest earned, which can further reduce your net return.

This isn’t to say CDs are bad in all inflationary periods—sometimes interest rates on CDs rise in response to inflation. But often, rates lag behind inflation, leaving savers in a losing game.

The Appeal of Safety vs. the Cost of Safety

Retirees often value safety over maximum returns, and with good reason. Market downturns can devastate a retirement portfolio if withdrawals are needed during a slump. CDs provide certainty: no matter what the market does, your principal and promised interest are secure.

However, that safety can be costly if inflation outpaces your returns year after year. Over a decade, even a modest gap between CD yields and inflation can result in thousands of dollars in lost purchasing power. The safety is real, but so is the hidden erosion.

Current CD Rates vs. Inflation in 2025

In 2025, many banks and credit unions are offering CDs with rates in the 4–5% range for terms of 12 to 36 months. Meanwhile, inflation has cooled from pandemic-era highs but still lingers around 3–4%, depending on which measure you look at.

On paper, that means some CDs are barely keeping pace with inflation or providing only a small real return. But the situation is more nuanced: if you expect inflation to fall further, locking in today’s relatively high CD rates could be a smart move. If you expect inflation to rise again, your locked-in rate could quickly become inadequate.

Taxes Make a Bigger Difference Than You Think

CD interest is taxed as ordinary income in the year it’s earned, even if you leave the funds untouched until the CD matures. This means your effective after-tax return could be significantly lower than the advertised rate, especially if you’re in a higher tax bracket.

For example, a 4.5% CD might yield only 3% after taxes if you’re in the 25% bracket. If inflation is also running at 3%, you’ve essentially earned nothing in real terms. Retirees living off fixed incomes must consider how taxes can turn a seemingly safe return into a break-even—or even negative—result.

The Liquidity Factor: What You Give Up

Liquidity is another often-overlooked factor. When you put money into a CD, you agree to keep it there for the entire term. Early withdrawals usually trigger penalties—often several months’ worth of interest. In an inflationary period, tying up money can also limit your ability to pivot if better opportunities arise.

If you lock into a 3-year CD at 4% and inflation pushes market rates to 6% a year later, you’re stuck unless you’re willing to pay the penalty. For retirees, this lack of flexibility can be problematic if unexpected expenses or better investment options emerge.

When CDs Still Make Sense in Inflationary Times

Despite the drawbacks, CDs aren’t obsolete. They can still make sense in certain circumstances:

• As part of a laddering strategy: By buying CDs with staggered maturities (e.g., 6 months, 1 year, 2 years), you reduce the risk of locking in at a bad rate while maintaining a steady flow of maturing funds to reinvest at potentially higher yields.
• For near-term expenses: If you know you’ll need funds in one to three years—say, for a planned move or a large purchase—CDs can be a safe parking place without the volatility of the stock market.
• As a cash alternative: For retirees who want part of their portfolio in ultra-safe assets, CDs can be a higher-yield alternative to savings accounts, especially if you shop around for the best rates.

Alternatives Worth Considering

If inflation is your primary concern, you may want to look beyond CDs to preserve or grow purchasing power:

• Treasury Inflation-Protected Securities (TIPS): These bonds adjust their principal with inflation, ensuring your real return stays positive.
• I Bonds: Similar to TIPS, but with purchase limits and some restrictions on redemption timing.
• High-Yield Savings Accounts or Money Market Funds: While rates can change frequently, these offer more liquidity than CDs and may keep up with or exceed CD yields during certain periods.
• Short-Term Bond Funds: These carry some market risk but can provide higher yields and flexibility compared to locking into a CD.

Shopping for the Best CD in a High-Inflation Era

If you decide a CD fits your needs, it pays to shop aggressively:

• Compare across banks and credit unions: Online banks often offer much higher rates than traditional brick-and-mortar institutions.
• Watch for special promotions: Some institutions run limited-time offers with rates far above their standard CDs.
• Mind the term length: In an uncertain inflation environment, shorter-term CDs give you more flexibility to reinvest if rates climb.
• Check penalties: Not all early withdrawal penalties are equal—some are steep enough to negate much of your interest if you cash out early.

The Psychological Factor

Many retirees place value not just on returns, but on peace of mind. Even if a CD’s real return is modest, the knowledge that your principal is safe can be worth it, especially if you have other investments generating higher returns to offset inflation risk.

For some, the discipline of locking away funds in a CD also prevents impulsive spending or ill-timed market moves. In this sense, CDs can serve as a behavioral finance tool as much as an investment vehicle.

Balancing Safety and Real Returns

In an ideal world, your safe investments would also keep pace with inflation, but reality often forces a trade-off. CDs offer safety, predictability, and simplicity, but in an inflationary environment, they rarely deliver strong real returns after taxes.

That doesn’t mean you should avoid them altogether—only that you should use them strategically and understand their limitations. The key is balancing your need for safety with the risk of losing purchasing power over time.

Are CDs Worth It in an Inflationary Economy?

Ultimately, CDs still have a role for retirees, but they are not the inflation-proof investment many assume them to be. If you value safety and predictability above all else, they can be a good tool for part of your portfolio. If your priority is preserving or growing purchasing power, you’ll need to look elsewhere for better inflation protection.

Should Retirees Use CDs in 2025 or Look Elsewhere?

The decision to invest in CDs during an inflationary period is deeply personal. For some, the stability outweighs the erosion of returns; for others, tying up funds at rates that may soon look small feels like a financial misstep.

The real question is: in your retirement, is the peace of mind from a guaranteed return worth the potential hidden cost of inflation over time? What would you choose—absolute safety or a little more risk for the chance at better returns?
