Overview

The Social Security cost-of-living adjustment (COLA) for 2027 will be announced on Wednesday, October 14, 2026, after the Bureau of Labor Statistics releases September inflation data. Forecasters project 3.3% to 3.6% — the largest increase since 2023.

The COLA is based on the Consumer Price Index for Urban Wage Earners (CPI-W). July and August readings already point to roughly a 3.4% increase; the September figure decides the final number.

For context: the 2026 COLA was 2.8% and 2025 was 2.5%. At 3.5%, the average retirement check of about $2,087 would rise by roughly $73 per month.

The increase applies automatically to retirement, survivor, disability, and SSI benefits — no application needed. It takes effect with December 2026 benefits, paid in January 2027 (SSI recipients see it December 31, 2026).

One offset to watch: the 2027 Medicare Part B premium, announced in mid-November, will absorb part of the raise for most beneficiaries.

Frequently asked questions

When is the 2027 COLA announced?
October 14, 2026, after the September CPI release at 8:30 a.m. ET.
How much will the 2027 COLA be?
Estimates range from 3.3% to 3.6%. The official figure comes October 14.
Do I need to apply for the increase?
No — it applies automatically to all Social Security and SSI benefits.
When will I see the higher payment?
January 2027 (your December 2026 benefit). SSI recipients: December 31, 2026.
Will Medicare eat the increase?
Partly — the 2027 Part B premium (announced mid-November) is deducted from most checks.
Is this a government website?
No. This is an independent guide. Official info: ssa.gov/cola.
How is the Social Security COLA actually calculated?
The COLA is set by law from the average Consumer Price Index for Urban Wage Earners (CPI-W) for July, August, and September, compared with the same period the previous year. If prices rose, benefits rise by that percentage; if prices fell, benefits stay flat — they never go down because of the COLA.
I just started receiving benefits — do I get the full COLA?
Generally yes, as long as you were entitled to benefits for December 2026, you receive the 2027 increase on your January 2027 payment. People whose first month of entitlement is after that date get the increase only from the COLA years that follow their start date.
How can I check my new benefit amount?
The Social Security Administration mails a notice showing your new amount in December 2026, and you can also see it in your my Social Security online account once the COLA is finalized. Never rely on a third-party estimate alone — the official notice is the authoritative figure.
Why does the COLA use CPI-W instead of regular inflation?
Congress chose CPI-W — which tracks spending by urban wage earners — as the statutory measure in the 1970s, before retiree-specific indexes like CPI-E existed. Critics argue it underweights seniors' health-care costs, which is why proposals to switch measures come up almost every year.
Will the 2027 COLA make more of my benefits taxable?
Possibly. Social Security becomes taxable when your combined income crosses federal thresholds that are not indexed to inflation, so a bigger COLA can push some retirees over the line. Review your expected income with a tax professional before filing season.
I got a call offering to 'activate' my COLA increase — is it real?
No — the COLA is automatic and the SSA will never call, text, or email asking you to pay a fee or confirm personal details to receive it. Hang up and report the call to the SSA's fraud hotline. Real communications about your benefit come by mail or through your official online account.
