What a Cost of Living Adjustment Is and When You Get One

A Cost of Living Adjustment (COLA) is an annual increase to your Social Security benefit amount, meant to keep your payment in line with inflation. Social Security calculates COLA each year using the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W), which measures price changes for food, housing, energy, and other goods. If prices rise between the third quarter of one year and the third quarter of the next, your benefit goes up by that same percentage in January.

You receive a COLA automatically if you are already collecting Social Security — you do not need to request it or take any action. The increase appears in your January payment. If you have not yet started collecting, the COLA still affects your account: your Primary Insurance Amount (the benefit amount you will receive when you claim) grows each year you delay claiming, which includes both the COLA increase and a separate increase for each year you wait past your Full Retirement Age.

COLA has not always been automatic. Before 1975, Congress voted on each adjustment separately. Since 1975, the adjustment has been tied directly to the CPI-W and happens without a vote, though Congress can change the formula if it passes new legislation.

Key Takeaways

  • Social Security calculates COLA each October using price data from July, August, and September, and the new amount takes effect in January.
  • The COLA percentage is the same for all beneficiaries — it does not vary based on how much you receive or when you claimed.
  • If inflation is zero or negative, there is no COLA increase that year, though your benefit amount does not decrease.
  • COLA affects your benefit whether you are already collecting or still working and delaying your claim.
  • Your spouse or ex-spouse's benefit on your record also receives the same COLA increase you do.

How the COLA Percentage Is Calculated Each Year

The Social Security Administration compares the average CPI-W for July, August, and September of the current year to the average for the same three months of the previous year. The percentage change between those two periods becomes the COLA for the following January. This calculation happens in October and is announced publicly by the Social Security Administration.

The CPI-W tracks prices paid by urban wage earners and clerical workers for items including food, gasoline, rent, medical care, and utilities. It does not include rural workers or retirees as a separate group. Some researchers and policy groups have argued that the CPI-W does not accurately reflect the spending patterns of older adults, who spend more on healthcare and less on transportation than the average wage earner, but Congress has not changed the formula.

If the CPI-W shows no increase or a decrease from one year to the next, there is no COLA that year. This happened in 2010, 2011, and 2016. Your benefit amount stays the same — it never decreases due to deflation or low inflation.

When COLA Takes Effect and How It Shows Up in Your Payment

The new COLA amount begins with your January payment each year. If you receive benefits by direct deposit, the increase appears in your bank account in early January. If you receive a paper check, it arrives by mail in January. You will also receive a notice from Social Security in December showing your new benefit amount and explaining the COLA increase.

The increase applies to your full benefit amount and to any benefits paid to your family members on your record. If you are married and both you and your spouse receive Social Security, you each receive your own COLA increase based on your individual benefit amounts. If you have adult children or a spouse caring for a child on your record, their benefits increase by the same percentage as yours.

If you claim Social Security partway through a year — say, in June — your first payment will not include a full year of benefits. When January comes, you receive the COLA increase on whatever amount you are already receiving, even though you have not been collecting for a full year.

COLA and Your Earnings Record Before You Claim

If you have not yet claimed Social Security, COLA still affects your future benefit in two ways. First, your Primary Insurance Amount (the benefit you will receive at your Full Retirement Age) is adjusted upward each year by the COLA percentage. Second, if you delay claiming past your Full Retirement Age, you earn an additional 8 percent per year until age 70, on top of the COLA increases that have already been applied.

This means that waiting to claim gives you two separate increases: the annual COLA adjustments that happen whether you claim or not, plus the delayed retirement credits that only accrue if you do not claim. Someone born in 1960 who waits from age 67 to age 70 to claim will receive a benefit that reflects three years of COLA increases plus three years of delayed retirement credits (24 percent total, before accounting for the specific COLA percentages in those years).

Your earnings record itself — the wages you paid Social Security taxes on — is also adjusted for inflation in the years before you turn 60. This adjustment is separate from COLA and uses a different index, but it means your benefit calculation accounts for wage growth over your working life.

COLA and Taxes on Your Benefits

A COLA increase can push you into a higher tax bracket for your Social Security benefits. If your combined income (adjusted gross income plus nontaxable interest plus half your Social Security benefits) exceeds certain thresholds, you may owe federal income tax on part of your benefits. Those thresholds are $25,000 for single filers and $32,000 for married filing jointly, and they have not changed since 1984.

Because the thresholds are fixed and COLA increases your benefit each year, more beneficiaries cross into taxable territory over time. This is sometimes called "bracket creep." If you are already paying tax on your benefits, a COLA increase will likely increase the taxable portion. If you are close to the threshold, a COLA increase might push you over it.

Some states also tax Social Security benefits, though the rules vary. A few states exclude Social Security from income tax entirely, while others tax it the same way the federal government does. Check your state's tax rules if you live in a state with an income tax.

Historical COLA Amounts and Why They Vary

COLA percentages have ranged from zero to over 14 percent in recent decades. The largest COLA on record was 14.3 percent in 1980, when inflation spiked due to oil prices and other factors. The smallest was zero percent in 2010, 2011, and 2016, when inflation was flat or negative. In 2022, COLA was 8.7 percent, the largest increase since 1981, reflecting rapid inflation that year.

COLA varies year to year because inflation itself varies. When energy prices spike, food prices rise, or housing costs jump, the CPI-W goes up faster, and COLA is higher. When prices stabilize or fall, COLA is lower or zero. You cannot predict COLA in advance because it depends on economic conditions that have not yet occurred.

The Social Security Administration publishes historical COLA amounts on its website, along with the year-by-year benefit amounts for someone who claimed at Full Retirement Age. These tables show how a benefit has grown over time for someone who has been collecting since a specific year.

How COLA Affects Your Household and Long-Term Planning

If you are married and both you and your spouse receive Social Security, COLA increases both payments. If one spouse receives a spousal benefit based on the other's record, that spousal benefit also increases by the COLA percentage. The same is true for divorced spouses and for adult children or grandchildren on your record.

When planning your retirement budget, assume that your Social Security benefit will increase each year, but do not assume a specific percentage. Some years COLA is high, some years it is low, and some years it is zero. A conservative approach is to budget based on your current benefit amount and treat COLA increases as a cushion.

COLA also affects how long your savings need to last. If you retire early and live on savings while delaying Social Security, your future benefit will be higher than it would have been if you claimed when ready, partly because of COLA increases that happen while you wait. This is one reason financial planners sometimes recommend delaying Social Security if you have other income sources available.

Frequently Asked Questions

Can I find out what my COLA increase will be before January?

Yes. The Social Security Administration announces the COLA percentage in October each year. You can find the announcement on the Social Security website or call 1-800-772-1213. The announcement tells you the percentage, and you can multiply your current benefit by that percentage to estimate your new amount.

What if I disagree with how Social Security calculated the COLA?

The COLA calculation is set by law and is not subject to individual dispute. If you believe your benefit amount is wrong for a different reason — such as an error in your earnings record — you can contact Social Security to request a review. Call 1-800-772-1213 or visit your local Social Security office.

Does COLA explore if I am still working and receiving Social Security?

Yes. If you are under your Full Retirement Age and still working, your benefit may be reduced due to earnings limits, but you still receive the COLA increase on your benefit amount. Once you reach your Full Retirement Age, the earnings limit no longer applies, and you receive your full benefit plus COLA.

If I delay claiming Social Security, do I get COLA increases on the amount I would have received?

Yes. Your Primary Insurance Amount (the benefit you would receive at Full Retirement Age) increases by COLA each year, whether you claim or not. When you eventually claim, your benefit reflects all the COLA increases that occurred while you were waiting, plus delayed retirement credits if you waited past Full Retirement Age.

Why does the COLA formula use the CPI-W instead of a measure that focuses on retirees?

Congress chose the CPI-W in 1975 when it made COLA automatic. Some researchers argue that the CPI-W does not reflect retiree spending patterns as well as other indexes would, but changing the formula would require new legislation. The Social Security Administration publishes data showing how different inflation measures would affect COLA if Congress decided to change the rule.
