What COLA changes
COLA adjusts Social Security and SSI benefit amounts to reflect inflation. It does not usually change the basic payment schedule rule.

Why 2027 searches start early
COLA estimates often appear before SSA announces the official number. Treat pre-announcement figures as scenarios, not final benefit promises.
Spousal benefit caution
Spousal benefits can depend on age, claiming timing and the worker's benefit. Use the spousal benefits COLA calculator when that is the specific amount you want to estimate.
How Social Security COLA Is Calculated
The official COLA is a formula-driven inflation adjustment, not a negotiated benefit raise.
Use CPI-W inflation data
SSA uses the Consumer Price Index for Urban Wage Earners and Clerical Workers, commonly called CPI-W.
Compare third-quarter averages
The key period is July, August and September. Estimates can move until the full third-quarter data is known.
Apply the final COLA to benefits
The new Social Security amount generally starts with January payments, while SSI timing can be affected by calendar rules.
2027 COLA Estimate vs. Official COLA
Pre-announcement numbers are planning scenarios. SSA is the official source for the final COLA and your personal benefit notice.
Medicare Part B and Net Increase
A higher Medicare Part B premium can reduce the take-home effect of a COLA. The optional Medicare field estimates that offset.
Who Should Use This Calculator
Use it for rough retirement, SSDI, SSI, survivor or spousal COLA math when you already know your current monthly benefit.

FAQ
Short answers for common Social Security payment-date questions.
What is the projected 2027 Social Security COLA?
The official 2027 COLA has not been announced. Current public estimates use inflation scenarios; The Senior Citizens League has recently cited a 3.8% scenario, while the final SSA number depends on third-quarter CPI-W data.
When will the 2027 Social Security COLA be announced?
SSA usually announces the next year's COLA in October after the July, August and September CPI-W data are available.
How is the Social Security COLA calculated?
The Social Security COLA is based on the increase in the Consumer Price Index for Urban Wage Earners and Clerical Workers, or CPI-W, comparing the third quarter of the current year with the third quarter of the prior year.
Does the 2027 COLA change my Social Security payment date?
No. COLA changes the benefit amount. Payment dates still follow SSA's normal schedule rules, including birthday groups, SSI timing and holiday adjustments.
Can Medicare Part B premiums reduce the COLA increase?
Yes. For many Medicare beneficiaries, a higher Part B premium can offset part of the gross monthly COLA increase. Use the optional Medicare field to estimate the net effect.
