Disability Benefits Calculator

Wondering how much you receive on disability? This calculator estimates your potential monthly Social Security Disability Insurance (SSDI) or Supplemental Security Income (SSI) benefit using your average indexed earnings, years worked, disability program, and state supplement. For 2026, the federal SSI maximum is $967 per month for an individual, while SSDI payments typically range from about $1,400 to $3,800 depending on lifetime earnings, with an average near $1,580. Plug in your numbers below for a realistic personalized estimate before applying.

The tool models the SSA's bend-point formula at a simplified level: it averages your reported earnings, applies the primary insurance amount (PIA) tiers, then adjusts for program type and state supplement. For example, a worker averaging $55,000 per year over 25 years often lands near $1,900 per month in SSDI, while an SSI-only recipient in a state with no supplement would receive at most $967. Your real benefit depends on SSA's exact AIME calculation, offsets, and household income, so treat this as an informed starting point.

How it works: Enter your average annual earnings, years of work, disability program, age band, and state tier. The calculator estimates monthly benefits and yearly totals.

Understanding Your Disability Benefit Amount in 2026

Disability payments aren't a single flat number — they depend on which program you qualify for, your earnings record, your household, and where you live. Here's how the math actually works.

SSDI vs SSI: Two Very Different Programs

SSDI (Social Security Disability Insurance) is an earned benefit — you must have worked and paid FICA taxes, generally 5 of the last 10 years for adults over 31. Your payment is based on lifetime earnings, with a 2026 maximum of $3,822/month. SSI (Supplemental Security Income) is needs-based with a flat federal max of $967/month for individuals and strict asset limits ($2,000 single, $3,000 couple). A rule of thumb: if you've worked steadily for 10+ years, SSDI will almost always pay more than SSI.

How the SSA Calculates Your SSDI Amount

The SSA averages your highest 35 years of indexed earnings to get your AIME (Average Indexed Monthly Earnings), then applies the bend-point formula: 90% of the first $1,226, 32% of earnings between $1,226 and $7,391, and 15% above that (2026 bend points). The result is your PIA — your monthly benefit. A common guideline: someone who earned around the national average wage their whole career receives roughly 40% of pre-disability income as SSDI.

State Supplements Can Add Hundreds

While the federal SSI maximum is $967/month in 2026, 44 states add their own supplement. California pays up to $240 extra (totaling $1,207), while New Jersey, Massachusetts, and New York add $80–$120. Six states (Arizona, Mississippi, North Dakota, West Virginia, plus Northern Mariana Islands) add nothing. Rule of thumb: if you're on SSI, moving from a no-supplement state to California can boost your check by ~25%, but only if you actually establish residency and meet that state's filing requirements.

Family and Dependent Benefits

SSDI recipients can also get auxiliary benefits for a spouse and minor children — typically 50% of the worker's PIA each, capped by a family maximum of 150–180% of PIA. So a worker getting $2,000/month with a spouse and two kids may see total household benefits near $3,400. SSI doesn't pay dependent benefits, but eligible couples receive a higher base ($1,450 in 2026). Rule of thumb: always apply for family benefits when filing SSDI — they don't reduce your own check.

How Other Income Affects Your Check

SSDI has no asset limit, but earnings above $1,620/month in 2026 (Substantial Gainful Activity, or $2,700 if blind) can disqualify you. SSI is much stricter: every $2 of earned income reduces your check by $1 after a $85 disregard, and unearned income reduces dollar-for-dollar after $20. Workers compensation and public disability pensions can offset SSDI so combined benefits don't exceed 80% of pre-disability earnings. Rule of thumb: report all income — unreported earnings cause overpayment notices averaging $9,000.

VA Disability Is Separate and Stackable

VA disability compensation is completely separate from SSDI/SSI and based on a 0–100% rating from service-connected conditions. 2026 rates range from $175/month (10%) to $3,831/month (100%, no dependents). VA benefits don't count against SSDI and only partially against SSI. A veteran rated 100% VA and also approved for SSDI commonly receives $5,000–$7,500/month combined. Rule of thumb: apply for both — VA approval can also expedite SSDI under the Wounded Warrior fast-track.

Typical Approval Timelines and Back Pay

Initial SSDI decisions take 6–8 months in 2026, with a 38% approval rate. Appeals (reconsideration then ALJ hearing) add another 12–18 months but raise overall approval to ~55%. The upside: SSDI back pay covers up to 12 months before your application date plus the wait, often totaling $15,000–$40,000 lump sum. SSI back pay starts from application date only. Rule of thumb: file the day you stop working — every month of delay typically costs you one month of back pay.

How This Calculator Works: Methodology & Parameter Explanations

Core formula: AIME = (average_income × min(work_years, 35)) / 420; PIA = 0.9×min(AIME,1226) + 0.32×min(max(AIME-1226,0),6165) + 0.15×max(AIME-7391,0); Monthly = PIA × age_adjustment, capped at $3,822 for SSDI; SSI = 967 + state_supplement, adjusted for household.

Parameter explanations

Assumptions

The headline figures referenced (like $1,580 average SSDI) are 2026 examples, not hard-coded limits — your actual benefit depends on your inputs.

We use simplified 2026 bend points ($1,226 and $7,391) and the $3,822 SSDI maximum; SSA's actual calculation indexes each year's earnings to national wage growth.

Earnings are treated as already indexed; for users far from retirement, real AIME may be 5–15% higher after SSA indexing.

State supplements are bucketed into tiers rather than per-state lookups; your actual state may pay slightly more or less.

VA estimates assume a 70% rating equivalent; actual VA pay varies by rating and dependents.

Tax, Medicare premiums, and workers-comp offsets are not deducted — results are gross benefits.
