What Is the Social Security COLA?
This calculator applies to United States Social Security and SSI benefits. Each year the Social Security Administration (SSA) announces a Cost-of-Living Adjustment (COLA) tied to inflation (the CPI-W). The COLA raises monthly benefit checks so retirees, survivors, and disability recipients keep pace with rising prices. This tool estimates your new monthly and annual benefit once a COLA takes effect (typically the January payment).
How to Use It
Enter your current monthly benefit in dollars and the announced COLA percentage. The calculator returns your new monthly benefit, the dollar increase per month, and the new annual total. For reference, recent COLAs include 8.7% (2023), 3.2% (2024), and 2.5% (2025).
The Formula
The math is simple percentage growth:
$$\text{New Benefit} = \text{Current Benefit} \times \left(1 + \frac{\text{COLA \%}}{100}\right)$$
The monthly increase is just \(\text{Current Benefit} \times \text{COLA \%} \div 100\), and the annual figures multiply the monthly values by \(12\).
Worked Example
Suppose your current monthly benefit is $2,000 and the announced COLA is 2.5%. Your new benefit is $$2000 \times (1 + 0.025) = \$2{,}050$$ That is a $50 monthly increase, $24,600 per year, or $600 more annually than before.
FAQ
Is the COLA applied before or after Medicare premiums? The COLA is applied to your gross benefit. Medicare Part B premiums are then deducted separately, so your net deposit may rise less than the gross COLA.
Does everyone get the same COLA percentage? Yes — the percentage is uniform, but the dollar increase varies because it is a percentage of each person's own benefit.
When does the COLA take effect? COLAs generally apply to benefits payable for December, which most recipients receive in their January payment.
