Social Security benefits are adjusted annually for inflation through Cost of Living Adjustments (COLAs). This calculator estimates your 2026 benefit increase based on current projections. Enter your current monthly benefit and the expected COLAs to see how much your payments will grow.
How to Calculate Social Security COLAs
The Social Security Administration (SSA) calculates COLAs using the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W). The formula for the COLA is:
COLA Percentage = (CPI-W for Current Year - CPI-W for Previous Year) / CPI-W for Previous Year × 100
This percentage is then applied to your current monthly benefit to determine your 2026 payment. The SSA typically announces COLAs in late October, with benefits increasing in December.
Note: COLAs are not guaranteed each year. If inflation is low, the COLA could be zero or even negative.
How to Use This Calculator
- Enter your current monthly Social Security benefit amount.
- Input the expected COLA percentage for 2026 (based on current projections).
- Click "Calculate" to see your estimated 2026 benefit.
- Review the breakdown of your new payment and compare it to your current benefit.
Formula Explained
The calculation is straightforward:
2026 Benefit = Current Benefit × (1 + COLA Percentage)
For example, if your current benefit is $1,500 and the COLA is 3.2%, your 2026 benefit would be $1,548.
Worked Example
Suppose you currently receive $1,800 per month and the expected COLA for 2026 is 2.5%. Here's how the calculation works:
$1,800 × (1 + 0.025) = $1,845
Your 2026 benefit would increase by $45 to $1,845 per month.
