SSDI lawyers charge a percentage of your back pay, not an hourly rate
Social Security sets the fee cap at 25 percent of your back pay, with a hard ceiling of $7,200 as of 2024. Back pay is the money Social Security owes you from the date you filed your claim to the date you were approved. Your lawyer does not charge you anything upfront, and if you do not win, you do not pay them. This is called a contingency fee arrangement.
The 25 percent rule applies to all SSDI and SSI (Supplemental Security Income) cases. If your back pay is $20,000, your lawyer's fee is $5,000. If your back pay is $30,000, the fee would normally be $7,500, but Social Security caps it at $7,200, so that is what you pay. The remaining back pay goes to you.
Your lawyer must file a fee petition with Social Security before they can collect anything. Social Security reviews the petition and either approves the fee, reduces it, or denies it. You will receive a notice of the decision. If you disagree with the fee amount, you have the right to object.
Key Takeaways
- SSDI lawyers work on contingency: they take a percentage of your back pay only if you win, and you pay nothing upfront.
- The fee is capped at 25 percent of back pay or $7,200, whichever is less, and is set by Social Security law, not by individual lawyers.
- Your lawyer must file a fee petition with Social Security, and you will receive written notice of the approved fee before any money changes hands.
- Back pay is calculated from your filing date to your approval date, so a longer wait between filing and approval means a larger back pay amount and a larger fee.
- If Social Security denies your claim and you appeal, you typically owe your lawyer nothing unless you eventually win at a later stage.
How back pay determines what your lawyer earns
Back pay is the single factor that controls your lawyer's fee. It is not based on how hard the case is, how many appeals you file, or how long your lawyer works on it. It is purely a percentage of the money Social Security owes you retroactively.
The calculation starts on the date you filed your claim with Social Security. If you filed in January 2022 and were approved in March 2024, Social Security calculates your monthly benefit amount and pays you for every month between January 2022 and March 2024 (minus any waiting period). That total is your back pay. Your lawyer's fee is 25 percent of that amount, up to $7,200.
This is why the timeline matters. A case that takes two years to win generates more back pay than a case that takes six months. A larger back pay means a larger fee for your lawyer, but also more money in your pocket. The fee is always proportional to what you receive.
When you might pay less than 25 percent
You pay less than 25 percent in two situations. First, if your back pay is small enough that 25 percent falls below $7,200, you pay 25 percent. For example, if your back pay is $10,000, your fee is $2,500, not $7,200. Second, if your back pay is large enough that 25 percent exceeds $7,200, you pay $7,200 flat, which is less than 25 percent of the total.
The $7,200 cap means that in high-back-pay cases, your lawyer's percentage actually drops. If your back pay is $40,000, the fee is $7,200, which is 18 percent. If your back pay is $50,000, the fee is still $7,200, which is 14.4 percent. This cap protects you in cases where you have waited a long time for approval.
Some lawyers may ask Social Security for a fee higher than the standard 25 percent in cases involving complex appeals or extensive work. Social Security can approve fees above 25 percent, but only in rare circumstances and only if the lawyer files a detailed petition explaining why the case was unusually difficult. This is uncommon and requires Social Security's written approval before the fee is collected.
What happens if your claim is denied
If Social Security denies your claim at the initial level, you owe your lawyer nothing. You have not received any back pay, so there is no fee to pay. Your lawyer can continue to represent you through the appeal process—reconsideration, hearing before an administrative law judge, or appeals council—still on contingency. You only pay if you eventually win at one of those levels.
If you win at the hearing stage after losing at reconsideration, your back pay is recalculated from your original filing date. Your lawyer's fee is 25 percent of that back pay (or $7,200, whichever is less). The fee covers all the work done from the initial claim through the hearing, even though you lost the first time.
Some readers hire a lawyer only after their initial claim is denied. The contingency arrangement still applies. The lawyer's fee is based on back pay from your original filing date, not from the date you hired the lawyer. This means your lawyer may do work on appeal that is not directly reflected in a higher fee, but they are betting on winning to earn anything at all.
The fee petition process and your right to object
After you win your case, your lawyer files a fee petition with Social Security. This petition states the amount of back pay you received and requests approval of the fee (25 percent or the amount the lawyer is asking for). Social Security reviews the petition and issues a written decision.
You will receive a copy of the decision. If you think the fee is too high or if you disagree with how the back pay was calculated, you have the right to object. You can file an objection with Social Security's Office of Hearings Operations. An administrative law judge will review your objection and the lawyer's petition and make a final decision on the fee.
Objections are uncommon because the 25 percent cap is set by law and applies to all cases. However, if your lawyer asked for a fee above 25 percent and Social Security approved it, you can object to that higher amount. You can also object if you believe the back pay calculation is wrong, which would lower the fee proportionally.
Costs beyond the lawyer's fee
Your lawyer's contingency fee covers their time and legal work. It does not cover out-of-pocket costs like obtaining medical records, ordering informed reports, or filing court documents. These costs vary by case and are separate from the lawyer's fee.
Some lawyers advance these costs and deduct them from your back pay after you win. Others ask you to pay costs as they occur. Before you hire a lawyer, ask in writing how they handle costs and whether they advance them or expect you to pay upfront. This should be spelled out in your representation agreement.
Costs are typically small—often $100 to $500 for a straightforward case—but they can be higher if your case requires medical informed testimony or extensive record requests. Make sure you understand the cost arrangement before signing the agreement.
How to find a lawyer and compare fees
All SSDI lawyers in the United States are bound by the same fee cap: 25 percent of back pay, up to $7,200. This means you cannot negotiate a lower percentage with a lawyer. The fee is the same whether you hire a solo practitioner or a large firm.
What you can compare is the lawyer's experience, their track record in your state, and how they handle costs. Some lawyers specialize in SSDI and have high approval rates. Others take on SSDI cases alongside other practice areas. Ask potential lawyers about their experience with cases similar to yours and what percentage of their SSDI cases result in approval.
You can find SSDI lawyers through the National Organization of Social Security Claimants' Representatives (NOSSCR), your state bar association, or a referral from a disability advocacy organization. Many offer free initial consultations. Use that time to ask about their process, their costs policy, and what they expect from you during your case.
Frequently Asked Questions
Can I negotiate a lower fee with my lawyer?
No. Social Security law sets the fee at 25 percent of back pay, up to $7,200. All SSDI lawyers must follow this cap. You cannot pay less by negotiating, and your lawyer cannot charge more without Social Security's approval in rare cases. The fee is fixed by law.
What if I win my case but receive no back pay?
This can happen if you filed your claim very close to your approval date, or if you were already receiving benefits under a different program. If there is no back pay, there is no fee. Your lawyer receives nothing. This is why the contingency arrangement protects you: you only pay if you actually receive money.
Do I have to use a lawyer to win SSDI?
No. You can represent yourself at any stage of the SSDI process. However, approval rates are significantly higher when a lawyer is involved, especially at the hearing stage. A lawyer's fee only comes out of money you would not have received otherwise, so the cost-benefit is often favorable.
Can my lawyer charge me if I lose my appeal?
No. Your lawyer only gets paid if you win and receive back pay. If you lose at every stage, you owe your lawyer nothing. This is the core of the contingency arrangement and is required by Social Security law.
How long does it take to get paid after I win?
Social Security typically issues your back pay within two to four weeks of approval. Your lawyer's fee is deducted from that payment and sent directly to your lawyer. You receive the remainder. The exact timeline depends on Social Security's processing speed and whether any issues arise with your case.
