YOUR RESULTS
Start with your numbers. We’ll work through the rest.
The 2027 Social Security cost-of-living adjustment is 3.6%. Enter your current gross monthly benefit to estimate the increase and a possible payment after the standard Medicare Part B premium. This is a simplified gross estimate, with a clearly labeled Medicare assumption. It cannot reproduce every step in SSA’s payment calculation. Your COLA notice is authoritative for your benefit and deductions. Start with the benefit before deductions, rather than the smaller amount deposited into a bank account.
How the 3.6% COLA was calculated
The statutory COLA uses the Consumer Price Index for Urban Wage Earners and Clerical Workers, called CPI-W. SSA compares the relevant third-quarter average with the comparison quarter used for the preceding adjustment. This looks at a defined price index over a defined period. It is not a prediction of next year’s inflation or a measure of every retiree’s personal expenses.
The published percentage applies to benefits under SSA’s rules. A household spending more on health care or housing may experience a different change in its budget. To review the announcement and the supporting figures, use the sources and update log. The calculator holds the current published COLA constant for this one-year comparison; it does not assume that future annual COLAs will match it.
When you will see the increase
The COLA applies to benefits for December 2026, paid in January 2027. The benefit month and the month the payment arrives are therefore different. Your regular payment schedule still determines the deposit date; this page does not calculate a personal payment calendar. You do not need to apply separately to receive the annual Social Security COLA.
SSI follows a different payment schedule. The increased SSI payment is scheduled for December 31, 2026, rather than the January Social Security schedule. If you receive SSI, use the FERS, CSRS and SSI guide to distinguish that program’s payment standard from a Social Security retirement benefit. A payment standard does not guarantee that every recipient receives the maximum.
How this calculator handles rounding
For a simple planning result, the calculator multiplies your current gross monthly benefit by the COLA growth factor and rounds the new gross estimate down to a whole dollar. The estimated dollar increase is the difference from the entered benefit. That describes this tool’s method; it is not a complete representation of SSA’s benefit calculation or every required rounding step.
SSA’s payment rounding instructions explain that final benefit rounding can occur after applicable deductions. The order of those operations can make your actual payment differ from a simplified gross estimate, even when you enter accurate figures. Use the amount on the official notice when reconciling a payment, and treat a small calculator difference as a reason to compare the inputs and deductions.
Why your net increase can be smaller
Medicare Part B premiums, tax withholding, and other deductions can change the amount reaching your account. The optional Part B subtraction uses the premium shown and its status; the 2027 standard premium is currently estimated at $209.50 per month. Read the Part B premium comparison before treating that estimate as a known deduction.
Higher-income beneficiaries may also owe IRMAA. The 2027 IRMAA brackets use earlier tax-return income and are separate from the COLA calculation. The calculator does not apply an unknown 2027 surcharge or determine individual hold-harmless protection. If you are working before full retirement age, the earnings limit calculator addresses another potential reason payments differ from a simple COLA estimate.
Use the average as context, not a personal prediction
SSA’s published average retired-worker benefit is $2,095 before the COLA and $2,170 after it. Those are national averages, not amounts assigned to your account. They also should not be treated as an example that this simplified calculator must reproduce exactly. Enter your own gross monthly benefit to obtain an estimate relevant to your starting amount.
Frequently asked questions
How much is the 2027 Social Security COLA?
The published COLA is 3.6%. The dollar change depends on your benefit. Apply the increase to the gross benefit and then review deductions; applying it only to a net bank deposit does not estimate the gross adjustment correctly.
When does the COLA start?
It applies to December 2026 Social Security benefits, paid in January 2027. The date of your individual payment follows your normal payment schedule. SSI’s increased payment has a separate December payment date.
Do I need to apply for the COLA?
No. The annual Social Security COLA is automatic for eligible benefits. This calculator does not submit an application, change your benefit record, or request bank information. You can review the change through your official notice.
Why is my net increase smaller than the COLA?
The COLA changes the gross benefit, while Medicare premiums and other deductions affect the net payment. Changes in those deductions and SSA’s payment rounding can make the bank deposit increase by a different amount.
When will I get my COLA notice?
Look for COLA notice information through your my Social Security account in late November, and check your notice preferences and SSA’s announcements for availability. The notice gives your personal benefit and deductions; this page cannot retrieve it.
