How to Calculate Your Maximum Social Security Disability Payment

Ever looked at your disability payment and wondered, “How does the Social Security Administration decide how much money I get?” Trust us, you’re not alone. Many people don’t realize how the agency determines each person’s maximum Social Security disability benefit amount. These calculations change a little bit every year, and they include more than your work history or highest annual salary. The SSA’s formula uses your average indexed monthly earnings, fixed percentages, and even cost-of-living-adjustment (COLA) increases.

The agency uses this same math to figure out both disability benefits and regular Social Security retirement payments. Below, we’ll break down each step in the SSA’s formula for you, step-by-step. That way, new applicants can get an idea of what their maximum Social Security payment might be every month. And while the words they use are sometimes confusing, we’ll explain what each term means as we go along.



How the SSA Calculates Your Maximum Social Security Benefits Amount

Step 1: Find Your Average Indexed Monthly Earnings (AIME)

First, let’s look at your Average Indexed Monthly Earnings (AIME). To find this amount, the SSA looks at how much money you earned while working over a 35-year period. If you have copies of your taxes from previous years, that’s a good place to start. (And if you don’t have those records, you can always ask the SSA or IRS to send them to you.) Once you have these numbers, the SSA then “indexes” each year’s earnings. This “index” reflects how much wage levels change annually based on increases in the average American’s standard of living. This “index” number should also account for things like inflation.

The SSA’s formula uses up to 35 years’ worth of your past earnings to determine your maximum Social Security payment. But what if you worked more than 35 years before filing your disability benefits application? In that case, they’ll choose the 35 years you earned the most money while working after they index your wages. Then, they’ll add those 35 years’ worth of indexed earnings together. Last, they’ll divide that number by the total months that are represented. Once you do that, the final number you get is your personal AIME. You need that AIME to determine how much your maximum Social Security disability benefits amount might be every month.

Step 2: Calculate Your Primary Insurance Amount (PIA)

Your Primary Insurance Amount (PIA) tells you how much money you may get each month in SSDI benefits. The SSA calculates this number using three different fixed percentages of your AIME that are added together. And while the percentages always stay the same, the three different dollar amounts based on your AIME change every year. These dollar amounts are known as “bend points,” which we will dive deeper into later.

Now that we know which numbers to look for, let’s look at the SSA’s internal PIA calculation formula. The agency’s PIA formula always uses the most current data from two calendar years prior to the current one. (That means the PIA formula below for calculating your maximum Social Security benefits uses bend point amounts from 2017.) Here’s the current PIA formula for people whose claims get approved for disability benefits in 2019:

  1. 90% of the first $926 of your average indexed monthly earnings, plus
  2. 3% of your average indexed monthly earnings over $926 and through $5,583, plus
  3. 15% of your average indexed monthly earnings over $5,583.

After calculating your PIA using the formula above, you’ll round that amount down to the nearest $.10. This final number should be your maximum Social Security benefits amount the SSA can pay you each month.

Understanding How Bend Points Affect Your Maximum Social Security Benefits Payment Amount

In step 2, I explained that the monetary amounts used to calculate your PIA are called “bend points.” However, they are so much more than that! The SSA also uses these bend points to calculate your family maximum Social Security benefits amount. That means if you die, your surviving spouse or dependents can apply for the maximum Social Security benefits they’re owed. These family maximum Social Security benefit payments are crucial for loved ones with little or no other income. However, the SSA determines each year’s unique bend points, so the amounts shown above are subject to change annually.

The SSA bases each year’s new bend points on the national Average Wage Index (AWI) series. The AWI is always two years behind, so people applying for disability benefits in 2019 will use 2017’s AWI. When the SSA first established bend points in 1979, they used the AWI from two years earlier (1977). In 1977, the AWI amount was $9,779.44. Those initial bend points were $180 for the first amount in the PIA formula and $1,085 for the second amount. This is important to know because each bend point determined since then is based on these first two dollar amounts.

For example, here’s how to calculate the PIA formula’s first bend point for 2019:

  1. Start with the 2017 AWI amount, which is $50,321.89
  2. Multiply that number by $180, which gives you $9,057,940.20
  3. Then divide that number by $9,779.44, which gives you $926.22
  4. Round that number down to $926, which is your final amount for 2019’s first PIA bend point

To calculate 2019’s second bend point:

  1. Start with the 2017 AWI amount, which is $50,321.89
  2. Multiply that number by $1,085, which gives you $54,599.250.65
  3. Then divide that number by $9,779.44, which gives you $5,583.07
  4. Round that number down to $5,583, which is your final amount for 2019’s second PIA bend point

Wonder how much these PIA formula bend points changed since 1979? Check out the SSA’s bend points chart here. That page also shows bend points for the family maximum benefit formula going back to 1979. To determine the bend points for your dependents, you can apply the same technique as we used above. The final number is your maximum Social Security benefits amount available for eligible dependents.

You May Qualify for Legal Assistance

If you find these complicated calculations and formulas confusing, you’re not alone. A lawyer can help you avoid claim mistakes that get many first-time applicants turned down. In fact, nearly 2 in 5 claimants get denied benefits for things like bad handwriting or leaving required fields blank! Luckily, you can get professional help now from an experienced Social Security attorney for free. A lawyer can help you decode legal jargon, collect proper medical records, and appeal your denial, if needed. Since these lawyers always work on contingency, you’ll pay nothing unless your case wins. And if you do win, you’ll only pay a small, one-time fee.
