Social Security recipients could see a larger cost-of-living adjustment in 2027 than the 2.8% increase applied to benefits in 2026. Current estimates have placed next year’s COLA around 3.5% to 3.6%, although the official figure will not be known until the Social Security Administration (SSA) announces it in October.
For retirees, however, a larger percentage increase does not automatically translate into significantly more spending power. Medicare costs, healthcare expenses and the way the COLA is calculated can all affect how far the additional money goes.
COLA
The 2027 Social Security COLA is not yet official. Current estimates have suggested an increase in the 3.5% to 3.6% range.
For context, a 3.5% increase on a monthly Social Security benefit of $2,000 would add about $70 per month before deductions. A 3.6% increase would add about $72.
The actual dollar increase will depend on the beneficiary’s current payment. Someone receiving a larger monthly benefit would see a larger dollar adjustment than someone receiving a smaller benefit.
The Social Security Administration’s official COLA information explains how annual adjustments are determined and provides the official figures once they are announced.
Medicare
One factor that can reduce the effect of a Social Security increase is the cost of Medicare Part B.
Many beneficiaries who have both Medicare and Social Security have their Part B premiums deducted directly from their Social Security payments. When the Part B premium rises, the increase in Social Security benefits can be partly offset.
The 2027 Part B premium has not yet been finalized. That means retirees cannot determine their exact increase in take-home Social Security income until both figures are available.
This distinction matters. A COLA is an increase in the gross Social Security benefit, while the amount actually reaching a beneficiary’s bank account can depend on deductions, including Medicare premiums and other withholdings.
Formula
There is another issue behind the debate over whether Social Security benefits keep pace with retirees’ expenses.
The Social Security COLA is calculated using the Consumer Price Index for Urban Wage Earners and Clerical Workers, or CPI-W. The measure tracks changes in prices across a broad basket of goods and services.
However, retirees can have spending patterns that differ from those of working-age households. Healthcare and housing, for example, can represent significant portions of an older person’s budget.
This is why some advocates have argued that an index designed specifically around older Americans’ spending patterns would provide a different measure of inflation.
The SSA explains the current COLA calculation, including the role of the CPI-W in determining the annual adjustment.
Inflation
A higher COLA can still leave some beneficiaries feeling that their budgets have not improved if their personal expenses rise faster than their Social Security payments.
Consider a retiree whose monthly benefit increases by $70. If healthcare, housing, food and other essential expenses rise by more than that amount, the additional Social Security income may not create much additional room in the household budget.
This does not mean the COLA has failed to increase benefits. Rather, it highlights the difference between a nominal increase in income and a change in purchasing power.
The Senior Citizens League has previously argued that Social Security’s purchasing power has declined over time. Its analysis is an advocacy group’s assessment, rather than an SSA measurement, and its methodology and conclusions should be distinguished from the federal government’s official COLA calculation.
Timing
The official 2027 COLA is expected to be announced in October 2026 after the relevant inflation data become available.
Until then, estimates remain estimates. The final percentage could differ from current projections, and the actual dollar increase for each beneficiary will depend on their existing benefit.
For retirees planning their 2027 budgets, it may therefore be useful to treat current COLA projections as planning assumptions rather than guaranteed increases.
Planning
The effect of a Social Security COLA ultimately depends on more than the headline percentage.
A beneficiary’s monthly Social Security payment, Medicare premiums, taxes, healthcare costs and other household expenses all influence how much additional income remains available for everyday spending.
That is why a 3.5% or 3.6% COLA should not automatically be interpreted as a 3.5% or 3.6% improvement in living standards. It is an adjustment to benefits, while household purchasing power depends on the relationship between income and expenses.
The 2027 increase could be larger than the 2026 COLA, but beneficiaries will need to wait for the official announcement and Medicare premium figures before they can determine the full effect on their monthly budgets.
