Inflation-adjusted annuity: The complete guide to protecting your purchasing power
Inflation remains a significant challenge for retirees as it often increases the cost of everyday expenses faster than fixed incomes can adjust. In January 2026, the U.S. Consumer Price Index (CPI) rose 2.4% year-over-year.
That’s where inflation-adjusted annuities come in, providing a built-in hedge against inflation.
An inflation-adjusted annuity is a lifetime income annuity contract designed to create an income stream that increases over time. It uses a fixed percentage or ties adjustments to an inflation index, such as the CPI.
“Their primary purpose is to protect income rather than chase returns,” said D’Andre Clayton, co-founder of Clayton Financial Solutions in Greensboro, North Carolina.
Below, we’ll dive deeper into what an inflation-adjusted annuity is and how it works, so you can decide if it makes sense for your particular risk tolerance and retirement goals.
The inflation challenge of fixed annuities
Let’s say you buy a fixed annuity that pays $2,000 per month for 25 years. Assuming a 3% inflation rate, that $2,000 will have the purchasing power of just $951 in year 25.
A grocery bill that is $200 this year could cost $419 in 20 years. Home repairs, medical premiums, and utility bills will all creep up as well.
“When you’re living on a fixed income, things seem stable at first. Then, inflation slowly chips away at your standard of living,” explained Eric Croak, certified financial planner and president at Croak Capital in Toledo, Ohio.
Inflation-adjusted annuities were designed to combat this issue and give retirees more peace of mind as the cost of goods and services continues to climb.
Understanding the tradeoff
An inflation-adjusted annuity might start with a lower initial payment of $1,700 per month, compared to a $2,000 fixed annuity. At first, you might feel like you’re losing money. However, with a 3% adjustment for cost of living, that $1,700 payment can turn into $2,280 by year 10 of your contract and $3,540 by year 25. By contrast, a fixed annuity will always remain at $2,000 per month, eroding your spending power.
Fixed vs. inflation-adjusted annuities: Key differences
Inflation-adjusted annuities were created as an alternative to fixed annuities, which offer a fixed income stream that doesn’t change for the duration of the policyholder’s life.
In most cases, inflation-adjusted annuities start off at a lower income level than their fixed counterparts. Over time, however, these products can surpass the payments of fixed annuities as they adjust to keep up with inflation.
“This allows future increases to be incorporated into the annuity’s structure, supporting future purchasing power,” explained Clayton.
Here’s a quick breakdown of how fixed and inflation-adjusted annuities compare:
| Feature | Fixed annuities | Inflation-adjusted annuities |
|---|---|---|
| Primary purpose | Guaranteed fixed income | Inflation protection |
| Payment amount | Stays the same over the life of the contract | Payments are lower at first but increase to keep pace with inflation |
| Inflation risk | Retiree assumes the risk | Insurer bears the risk |
| Growth potential | Base on a fixed interest rate | Adjusted periodically based on an inflation index |
While fixed annuities are ideal for retirees who are seeking stable, predictable income, inflation-adjusted annuities make more sense for those who are concerned about inflation and the rising costs that erode purchasing power.
Cost-of-living adjustments (COLA) in annuities
Cost-of-living adjustments, or COLAs, are set increases that occur regardless of actual inflation rates. Inflation-adjusted annuities use several COLA structures, including:
- Fixed percentage: Payments usually rise by 3% to 5% each year.
- CPI-linked: Payments change annually based on the CPI or another inflation index.
- Step-up or deferred: Some annuities begin with lower payments, and the COLA adjustments start after a specific period.
- Cap: Payments typically go up with inflation, but have minimum and maximum limits.
It’s important to note that while COLAs are predictable, they can fall short during periods of high inflation. That being said, their implications are relatively straightforward.
“Since the insurer assumes more risk with inflation indexing, they typically reduce your starting income by 15% to 25% when compared to a level annuity payment. Indexed contracts can also have added complexity and fewer annuity carrier options,” explained Croak.
Inflation-adjusted annuities vs. Treasury Inflation-Protected Securities (TIPS)
At first glance, inflation-adjusted annuities and Treasury Inflation-Protected Securities (TIPS) might seem similar, but there are noteworthy differences between the two products.
Backed by the U.S. government, TIPS adjust based on the CPI. While they hedge against inflation, they don’t provide lifetime income. The investor still bears longevity risk and must manage withdrawals.
An inflation-adjusted annuity, on the other hand, pools mortality risk. It converts the capital into guaranteed lifetime income, potentially adjusted for inflation, but sacrifices liquidity.
“While TIPS are securities or market-based instruments, adjusted annuities are liability-matching insurance tools. One protects the purchasing power of capital, while the other protects the purchasing power of income,” said Clayton.
One isn’t necessarily better than the other. The ideal choice depends on your unique situation and goals.
When does an inflation-adjusted annuity make sense?
While inflation-adjusted annuities can be worthwhile, they’re not right for every investor. You should only consider them if any of the following apply to you:
- You’re worried about inflation: If rising costs of housing, groceries, or healthcare make you nervous, an inflation-adjusted annuity can ensure your income keeps up during your retirement.
- You believe you’ll have a long retirement: A longer retirement is more susceptible to higher inflation, so if you plan for your nest egg to last you multiple decades, an inflation-adjusted annuity can be a smart investment.
- You accept a lower initial income: Due to the insurer’s risk of inflation-adjusted annuities, you’ll need to be comfortable with lower payments than you might get with fixed annuities.
- You prefer predictable spending power growth: COLA adjustments might not align with inflation perfectly every year, but they can allow you to maintain your income relative to increasing costs.
How to shop for inflation-adjusted annuities
If you’re interested in inflation-adjusted annuities, these steps can help you hone in on the right products.
- Do your research: Don’t go with the first option you find. Shop around and compare inflation-adjusted annuities from at least a few different insurance companies.
- Gain clarity: Make sure you understand how COLAs are calculated, whether there are minimum or maximum payouts, what fees are involved, and whether you can add annuity riders or choose hybrid features.
- Check financial strength and ratings: Check each insurance company’s ratings from organizations such as AM Best, Fitch, and S&P Global Ratings to gauge its reputation and how likely it is that you’ll receive your payments.
- Look for red flags: Stay away from annuities with overly complicated COLA structures, exorbitant fees, and products from insurers with poor financial strength or many negative reviews.
The bottom line: Is an inflation-adjusted annuity right for you?
Inflation-adjusted annuities can be a great way to protect against inflation and ensure your retirement income lasts despite rising costs of living. However, these products come with a higher upfront investment and lower initial payments. If preserving purchasing power is one of your top priorities, they may still be worth it. Speak with a trusted financial advisor to determine if an inflation-adjusted annuity fits well into your financial plan.
Frequently asked questions about inflation-adjusted annuities
How much do inflation-adjusted annuities cost?
Inflation-adjusted annuities usually involve a higher initial premium than fixed annuities to offset the insurance company’s risk. Minimum investment amounts vary greatly by insurer, but in most cases, you may encounter additional expenses, such as management fees, administrative costs, and riders that may further boost income protection.
You may also face early withdrawal charges if you pull money out of your annuity early. In addition, starting payments are typically 15% to 25% lower than fixed annuities, but the trade-off is that your future income increases with inflation. It’s up to you to decide if higher premiums and lower starting payments are worth it.
Can I customize annuity inflation protection?
There are several ways to customize inflation-adjusted annuities to meet your particular retirement horizon and risk tolerance. Some insurance companies let you choose your COLA structure, as well as when you want your inflation adjustments to begin.
Depending on the insurer, you may also opt for partial protection that increases your income for a fraction of inflation, such as 30% of CPI growth. With this option, you may boost your initial payments and still hedge against inflation. Additionally, there are hybrid annuities that pair fixed income with an inflation-adjusted component.
What happens to my inflation-adjusted annuity if inflation goes negative?
Most inflation-adjusted annuities are designed to prevent payments from declining. Even if the CPI falls, your payments may not decrease. Many of these products include a “floor,” which means your payments will never dip below the initial amount. Some inflation-adjusted annuities feature a minimum annual increase as well, so your payments will still go up even if inflation is zero.
