The possible increase is drawing attention because it would top the 2.8% boost set for 2026. The catch: a larger COLA usually means prices are still biting household budgets.
Social Security recipients in the United States could see a larger cost-of-living adjustment in 2027, with the latest forecast for the 2027 Social Security COLA at 3.8%—an increase that would add about $73.62 to the average retired worker’s monthly check if it held. Inflation could push the COLA higher, or lower, before the Social Security Administration makes it official; 75 million Social Security and SSI beneficiaries are already getting a 2.8 percent increase in 2026, after notices began in late November 2025.
That is not a final raise. It is a forecast built around inflation data, and it comes with a familiar tradeoff for retirees: bigger benefit increases usually arrive when everyday costs are also rising faster.
The number retirees are watching
A House website post from Rep. John Larson’s office cited a 3.8% forecast for the 2027 Social Security cost-of-living adjustment. At that level, the average retired worker’s monthly benefit would rise by about $73.62.
For people living mostly on Social Security, that number matters because the COLA is one of the few automatic protections built into retirement income. It is designed to keep benefits from losing purchasing power when prices climb.
The forecast also stands above the 2.8% increase the Social Security Administration has announced for 2026 benefits. That 2026 increase applies to Social Security and Supplemental Security Income benefits for roughly 75 million Americans, according to the agency.
The 2027 estimate is drawing attention because it suggests inflation may remain sticky enough to produce a larger adjustment the following year.
Why inflation cuts both ways
A larger COLA can feel like a win when grocery bills, rent, insurance and utilities keep moving higher. But it is not extra money in the usual sense. It is compensation for inflation that has already made life more expensive.
The Bureau of Labor Statistics reported that the Consumer Price Index for Urban Wage Earners and Clerical Workers, known as CPI-W, rose 3.9% over the prior 12 months in its April 2026 data release. That measure is central to how Social Security COLAs are calculated.
If inflation cools in the months that count for the official formula, the 2027 COLA could come in lower than 3.8%. If inflation accelerates, it could land higher. That is why estimates can move month to month.
Some expert forecasts have recently put the possible 2027 COLA in the high-3% range. CNBC reported in July that cooling inflation had lowered some expectations to between 3.7% and 3.8%, underscoring how sensitive the estimate is to new price data.
How the COLA is set
The Social Security Administration does not pick the COLA based on budget politics or a general sense of whether retirees need more money. By law, the agency uses CPI-W as the official inflation measure for COLA calculations.
The key comparison is not the full-year inflation rate. The COLA is based on the average CPI-W for the third quarter—July, August and September—compared with the same period a year earlier.
That means the final 2027 figure will depend heavily on price readings in the second half of 2026. A forecast in the summer can be useful for planning, but it can still change before the official announcement.
Once the Social Security Administration sets the COLA, the increase generally shows up in January benefit payments for the new year. SSI payment timing can differ slightly because of calendar rules.
What 3.8% would mean
The cited estimate says a 3.8% COLA would add about $73.62 to the average retired worker’s monthly Social Security benefit. Individual increases would vary because the COLA is applied as a percentage of each person’s current benefit.
For rough planning, a 3.8% adjustment would look like this before any deductions or offsets:
- A $1,500 monthly benefit would rise by about $57.
- A $2,000 monthly benefit would rise by about $76.
- A $2,500 monthly benefit would rise by about $95.
Those examples show why percentages can be misleading. A higher earner with a larger benefit receives a bigger dollar increase, while people with smaller checks may still struggle to cover rising fixed costs.
For households that rely on Social Security for most of their income, the practical question is not whether the COLA sounds large. It is whether the increase keeps pace with the bills that dominate their budget.
Why 2026 comes first
Before any 2027 increase arrives, beneficiaries are dealing with the 2026 COLA. The Social Security Administration says Social Security and SSI benefits for 75 million Americans will increase 2.8% in 2026.
The agency also says beneficiaries can receive COLA notices online or by mail, with notice activity tied to late November 2025 for the 2026 increase. Those notices spell out the new benefit amount for each person.
The contrast between 2.8% for 2026 and a possible 3.8% for 2027 is the reason the new forecast is getting attention. It suggests the next adjustment could be meaningfully larger if inflation does not cool enough before the formula period closes.
Still, beneficiaries should be cautious about treating the 3.8% estimate as money already in hand. The official number has not been locked in.
The planning takeaway for households
The best use of the forecast is as a planning range, not a promise. A 3.8% COLA would help many retirees absorb higher costs, but it would also signal that inflation remains a pressure point for older households.
There are also open questions beyond the headline percentage. Future inflation readings, Medicare premium changes, tax situations and household expenses can all affect how much relief people actually feel in their monthly budgets.
The clean takeaway: Social Security recipients may be on track for a larger cost-of-living adjustment in 2027 than they received for 2026, with the current forecast around 3.8%. But the final answer belongs to the inflation data—and the Social Security Administration’s official calculation.
