Your 2027 Social Security payment increase is not known yet. The Social Security Administration estimates a 2.4% cost-of-living adjustment (COLA), the annual inflation-based benefit increase, but will not announce the official rate until October 2026. At 2.4%, a $2,000 gross monthly benefit would rise by about $48 to $2,048. Your actual increase and bank deposit may differ because of rounding and deductions.

When Will the 2027 Increase Be Final?
The COLA depends on the change in the CPI-W, an inflation measure, from the third quarter of 2025 to the third quarter of 2026. The final calculation requires CPI-W figures for July, August, and September 2026. The Bureau of Labor Statistics has scheduled those releases for August 12, September 11, and October 14, respectively.
September's figure, released in October, completes the data needed for the calculation. SSA says it will announce the next COLA in October 2026. Until then, any 2027 percentage is an estimate rather than a guaranteed increase.
Why 2.4% Is the Current Estimate
SSA's fiscal year 2027 budget assumes a 2.4% COLA payable in January 2027. Its Supplemental Security Income budget uses the same assumption.
That agreement makes 2.4% a useful planning figure, but it does not make the rate official. The statutory calculation will determine the final percentage after all three months of third-quarter CPI-W data are available.
What Would a 2.4% Increase Mean?
A quick estimate is $24 more per month for every $1,000 in gross benefits: These are planning examples, not exact payment forecasts. SSA applies the COLA to the underlying benefit calculation and then rounds, so simply multiplying your current payment may produce a slightly different result.
- $1,000 would become about $1,024.
- $1,500 would become about $1,536.
- $2,000 would become about $2,048.
- $2,500 would become about $2,560.
Why Your Deposit May Increase by Less
The COLA applies to your gross benefit, not necessarily the amount deposited into your bank account. Medicare premiums and other offsets are deducted before SSA rounds the final monthly payment.
As SSA's COLA calculation guidance explains, those adjustments can make the change in your net deposit different from the headline COLA. Compare gross benefits when checking the percentage increase, then review deductions separately.
How to Plan Before October
Use 2.4% as a working estimate, not as confirmed income. Keep some room in your 2027 budget in case the final rate differs. The latest confirmed benchmark is the 2.8% COLA for 2026, which began with December 2025 benefits paid in January 2026.
That rate does not predict the 2027 adjustment. If you have not started benefits, use SSA's my Social Security benefit estimate as your starting amount. Apply 2.4% for a provisional 2027 figure, then replace it with SSA's official rate after the October announcement.
