If faith and politics are off limits at the dinner table, fall conversation often turns to weather, football, and finances. Once everyone has commented on how quickly summer’s heat gave way to cooler days, an easy pivot is, “So, how crazy was the market this week?” That conversation might also turn to another financial headline: Social Security’s announcement of a 3.6% cost-of-living adjustment for 2027. But what does that increase actually mean, and what should you know before weighing in over dinner?¹
Understanding COLA starts with a few questions: Who receives it? How is it calculated? When does it arrive? And why might the same percentage increase feel helpful to one person and barely noticeable to another?
What is COLA supposed to do?
COLA stands for cost-of-living adjustment. Its purpose is to help Social Security benefits keep pace with inflation - that unwelcome word we hear when everyday prices rise.
Think about your grocery cart. If the same collection of groceries costs more this year, an unchanged monthly benefit buys less. COLA helps close that gap. The goal is to help you afford the familiar shopping list, although the increase cannot guarantee that every household’s higher expenses will be covered.
Automatic adjustments also mean beneficiaries do not have to wait for Congress to approve a separate increase each year. There is an established process for adjusting benefits in response to measured inflation,¹ which helps with predictability and planning.
Who receives the adjustment?
Most of us would welcome an annual pay increase, but the Social Security COLA is not an across-the-board raise. It applies to Social Security retirement, disability, and survivor benefits, as well as federal Supplemental Security Income (SSI) payment levels. Although often associated with retirement, you do not necessarily have to be retired to benefit.²
Consider a 64-year-old who continues working and waits until 67 to claim retirement benefits. Applicable COLAs are incorporated into the underlying benefit calculation during that waiting period. They do not need to start collecting checks to receive those adjustments. The effect of their claiming age is calculated separately.³
Now consider a 45-year-old who works and receives no Social Security benefits. The announced COLA does not automatically increase their paycheck or add 3.6% to their future retirement benefit. Their future benefit follows separate earnings-based rules.³ For that person, the immediate concern may be the inflation behind the headline: groceries cost more, but their employer has not necessarily increased their salary.
What does 3.6% mean in actual dollars?
The percentage is only the starting point. The dollar increase depends on the size of the benefit.
| Monthly benefit before COLA |
Approximate monthly increase |
Benefit after COLA, before deductions |
|---|---|---|
| $1,000 | $36 | $1,036 |
| $2,000 | $72 | $2,072 |
| $3,000 | $108 | $3,108 |
These simplified examples show why two friends can receive the same percentage adjustment and different dollar increases.
There is another number to consider: the amount deposited into the bank account. The benefit before deductions is not necessarily the amount available to spend. Medicare premiums, voluntary income-tax withholding, and other deductions can affect that payment.⁴
Suppose someone’s benefit rises by $72 a month, but their deductions increase by $10. Their deposit increases by $62. If their other monthly expenses also rise by $62, the additional money is already spoken for.
That is the difference between a larger payment and greater purchasing power. The bank balance has increased, but the grocery cart strain may look exactly the same.
Who calculates COLA, and how?
Three government bodies have distinct roles on the COLA team:
Congress sets the rules through legislation.
The Bureau of Labor Statistics (BLS) measures price changes through the Consumer Price Index for Urban Wage Earners and Clerical Workers, or CPI-W.
The Social Security Administration (SSA) applies the formula, announces the adjustment, and updates benefits.¹˒⁵
Think of Congress as writing the rulebook, BLS as supplying the price information, and SSA as doing the calculation and putting the result into practice.
For anyone who wants to geek out on the math, SSA calculates the 2027 adjustment by comparing the average CPI-W for July, August, and September 2026 with the average for those months in 2025:
COLA = [(2026 third-quarter average − 2025 third-quarter average) ÷ 2025 third-quarter average] × 100
Using the official index readings:
[(328.746 − 317.265) ÷ 317.265] × 100 = approximately 3.62%
Rounded to the nearest tenth of a percentage point, the result is 3.6%. The calculation uses a national measure of price changes, rather than each beneficiary’s receipts.⁵ No one at SSA is reviewing your individual grocery bill.
What if you are still working?
Collecting Social Security and retiring from work are separate decisions. If someone receives retirement benefits before full retirement age and continues working, the retirement earnings test may affect their payments.
The earnings test determines whether SSA must withhold some benefits when a beneficiary’s earnings from work exceed a specified limit before full retirement age. It does not prohibit someone from working or earning more; it affects how much Social Security pays them during that period.⁶
The 2027 rules are:
Below full retirement age all year: SSA withholds $1 in benefits for every $2 earned above $25,560.
Reaching full retirement age during 2027: SSA withholds $1 for every $3 earned above $67,920, counting only earnings before the month full retirement age is reached.
Beginning with the month full retirement age is reached: Earnings no longer reduce retirement benefits.²
For example, imagine a 64-year-old collecting retirement benefits while earning $35,560 from a part-time job. Assuming they remain below full retirement age throughout the year, their earnings exceed the limit by $10,000. SSA would withhold $5,000 in benefits under the annual test.
A 45-year-old earning the same amount and receiving no benefits has no retirement payment to withhold. A 68-year-old receiving retirement benefits has passed full retirement age, so this earnings restriction no longer applies.
For this test, earnings generally mean wages and net self-employment income, rather than pensions or investment income. Disability benefits and SSI have separate work rules.²˒⁶
These limits are separate from COLA and use formulas tied to national wage growth.⁷ Also, “withheld” is more accurate than “lost”: at full retirement age, SSA recalculates retirement benefits to credit months affected by the earnings test. This adjusts future monthly benefits rather than providing a lump-sum refund.⁸
Why does the same adjustment feel different to different people?
Imagine two friends, Dan and Lauren, each receiving a $2,000 monthly benefit. Both receive approximately $72 more before deductions.
In this hypothetical example, Dan’s combined monthly housing, transportation, and healthcare costs rise by $45. Lauren faces a rent increase, higher driving costs, and additional medical expenses totaling $175 a month.
Dan’s adjustment covers those increases with $27 remaining. Lauren faces a $103 gap. Other expenses and deductions are assumed unchanged.
Same COLA, different conversations when the bills arrive.
Someone with a stable mortgage payment may experience housing costs differently from a renter facing a lease renewal. A person who rarely drives may feel fuel-price changes less than someone who travels regularly for medical appointments. BLS emphasizes that an average inflation measure cannot precisely reflect every household’s experience.⁹
That helps explain the policy debate. CPI-W reflects spending patterns among urban wage earners and clerical workers, which may differ from those of retirees and people with disabilities. Policymakers debate whether another measure would better serve beneficiaries and how changes would affect fairness and program costs. The challenge is choosing a shared measure for people whose household budgets can look very different.
When will beneficiaries see the increase?
The 2027 adjustment begins with Social Security payments received in January 2027. Increased SSI payments for January arrive on December 31, 2026, because January 1 is a holiday. Beneficiaries can review their individual COLA notice for updated payment information.¹⁰
The timing matters: the calculation looks backward at measured inflation, while beneficiaries must use the adjusted payments to meet the expenses ahead.
Your next dinner conversation
Understanding COLA gives you more than a headline to repeat. You can explain why the same percentage produces different dollar increases, why deductions matter, and why a bigger payment may still leave someone’s budget feeling tight.
A financial advisor can help connect these details to a broader retirement plan, including Social Security claiming decisions, taxes, healthcare costs, and savings withdrawals. Regular budget reviews and planning for different scenarios can help you prepare for changing expenses. While no one can predict every price increase, building flexibility into a plan can make those changes easier to navigate.
So when the conversation turns from weather and football to finances, you can contribute a useful observation: “The increase matters - but what it buys depends on the household.” That is a conversation worth having before anyone passes the dessert.
