What Changed in Social Security's Calculation

In January 2024, Social Security switched from using the Primary Insurance Amount (PIA) formula to a new method that affects how your monthly benefit is calculated. The change applies to people who reach full retirement age starting in 2024. Instead of the previous three-bend-point formula that had been in place since 1979, Social Security now uses updated bend points that reflect current wage levels more accurately.

The bend points are the income thresholds where your benefit calculation rate changes. Under the old formula, these thresholds had not moved in decades relative to actual wages people earn today. The new bend points are higher, which means more of your earnings fall into the lower-percentage brackets. For most workers, this results in a smaller monthly benefit than the old formula would have produced, though the exact difference depends on your lifetime earnings record.

This is not a change to when you can claim, how long you have worked, or what your full retirement age is. It only affects the math Social Security uses to turn your earnings history into a dollar amount.

Key Takeaways

  • Social Security updated its bend-point formula in 2024, meaning the income thresholds used to calculate benefits moved higher to match modern wage levels.
  • The new formula typically results in a lower monthly benefit for people reaching full retirement age in 2024 and beyond, compared to what the old formula would have paid.
  • Your earnings record, work history, and full retirement age have not changed — only the calculation method changed.
  • You can see your estimated benefit amount on your Social Security statement, which reflects the current formula.
  • The change does not affect people already receiving benefits or those who claimed before 2024.

How the Bend Points Work

The bend-point formula takes your average indexed monthly earnings (AIME) and applies different percentages to different portions of that amount. The first portion gets a higher percentage, the middle portion gets a lower percentage, and the highest portion gets an even lower percentage. This structure is designed to replace a larger share of income for lower-wage workers and a smaller share for higher-wage workers.

For 2024, the new bend points are $1,174 and $7,078. This means the first $1,174 of your AIME is multiplied by 90 percent, the amount between $1,174 and $7,078 is multiplied by 32 percent, and anything above $7,078 is multiplied by 15 percent. Under the old formula, those thresholds were much lower, so more of your earnings fell into the higher-percentage brackets.

Because the bend points moved up, workers with average or above-average earnings see a larger portion of their income fall into the lower-percentage brackets. Workers with very low lifetime earnings may see little change, since most of their income already fell in the highest-percentage bracket under both formulas.

Who This Change Affects

The new calculation applies only to people who reach their full retirement age in 2024 or later. If you were born in 1958 or later, you will use the updated bend-point formula when you claim benefits. If you were born in 1957 or earlier, your benefit was calculated under the old formula, and that does not change.

People who already receive Social Security benefits are not affected. Their monthly payment stays the same (though it may increase with annual cost-of-living adjustments). The change also does not affect Supplemental Security Income (SSI), which is a separate needs-based program.

If you are still working and have not yet reached full retirement age, your future benefit estimate on your Social Security statement already reflects the new formula, so you can see the projected amount you would receive.

Why Social Security Made This Change

The bend points had remained at $680 and $4,102 since 1979. Over 45 years, average wages in the United States rose significantly, but the formula thresholds did not. This meant the formula was no longer accurately reflecting the wage structure it was designed to measure.

By updating the bend points to current wage levels, Social Security brought the formula back into alignment with its original intent: to replace a higher percentage of low-wage earnings and a lower percentage of high-wage earnings. Without this adjustment, the formula would have become increasingly distorted as wages continued to rise.

The change was not made to reduce overall benefits or to address Social Security's long-term funding challenges. It was a technical adjustment to make the calculation method work as originally designed.

How to Find Your Estimated Benefit Under the New Formula

You can view your estimated benefit amount on your Social Security statement, which is available at ssa.gov. Create a my Social Security account, and you will see your projected monthly benefit at full retirement age. This estimate already includes the new bend-point formula if you have not yet reached full retirement age.

Your statement also shows your earnings record — the wages Social Security has on file for each year you worked. If you spot an error, you can correct it through your account. Errors in your earnings record directly affect your benefit calculation, so it is worth reviewing.

If you do not have an online account, you can request a paper statement by calling Social Security at 1-800-772-1213 or visiting your local Social Security office. The statement will show your estimated benefit under the current formula.

What Happens If You Claim Before Full Retirement Age

If you claim Social Security before you reach full retirement age, your benefit is reduced by a percentage that depends on how many months early you claim. This reduction is applied after your benefit is calculated using the bend-point formula. So the new formula affects your full retirement age amount, and then the early-claim reduction is applied on top of that.

For example, if the new formula produces a lower full retirement age benefit than the old formula would have, your reduced early-claim amount will also be lower. The relationship between claiming early and the reduction percentage has not changed — only the starting amount has.

Comparing Your Benefit Under Both Formulas

If you want to see what your benefit would have been under the old formula, you would need to do the math yourself or contact Social Security directly. Social Security does not automatically provide a side-by-side comparison, but the agency can calculate it for you if you ask.

The difference varies widely depending on your earnings history. Someone with very high lifetime earnings might see a reduction of several hundred dollars per month. Someone with low lifetime earnings might see little or no change. Someone with mid-range earnings typically falls somewhere in between.

Keep in mind that this is a one-time change to the formula, not an ongoing reduction. Your benefit amount will still increase with annual cost-of-living adjustments, just as it would have under the old formula.

Frequently Asked Questions

Does this change affect my current Social Security check?

No. If you are already receiving benefits, your monthly payment does not change because of the formula update. The new bend points only explore to people who reach full retirement age in 2024 or later. Your benefit may still increase with annual cost-of-living adjustments, but that is separate from this change.

Can I see what my benefit would have been under the old formula?

Social Security does not show this automatically on your statement, but you can ask the agency to calculate it. Call 1-800-772-1213 or visit your local office and explain that you want to see your benefit under both the old and new formulas. They can provide both numbers so you can compare.

Does this mean Social Security is running out of money?

The bend-point change is not related to Social Security's long-term funding situation. It is a technical adjustment to make the calculation formula work as it was originally designed. Social Security's funding challenges are a separate policy issue that Congress would need to address.

Will the bend points change again next year?

The bend points are adjusted each year based on changes in average wages. So the exact numbers will be different in 2025, 2026, and beyond. Social Security publishes the new bend points each October for the following year, so you can check ssa.gov to see the updated thresholds.

If I delay claiming past full retirement age, does the new formula still explore?

Yes. The new bend-point formula is used to calculate your full retirement age benefit amount, regardless of when you actually claim. If you delay claiming, your benefit increases by a percentage for each month you wait, but that increase is applied to the amount calculated under the new formula.
