If you're searching this question, it's worth knowing upfront: EDD disability and SSDI are two separate programs, and many Californians qualify for — or receive — both. Understanding what each pays, how those amounts are calculated, and what affects your specific benefit requires separating the two clearly.
California's Employment Development Department (EDD) administers State Disability Insurance (SDI) — a state-run, short-term program funded through payroll deductions. It is not the same as Social Security Disability Insurance (SSDI), which is a federal program administered by the Social Security Administration (SSA).
| Feature | California SDI (EDD) | Federal SSDI (SSA) |
|---|---|---|
| Administering agency | California EDD | Social Security Administration |
| Duration | Up to 52 weeks | Long-term or permanent |
| Funded by | Employee payroll deductions | FICA payroll taxes |
| Eligibility basis | Recent wages + medical certification | Work credits + disabling condition |
| Average benefit | ~60–70% of weekly wages | Based on lifetime earnings record |
Both programs use different formulas, different definitions of disability, and different eligibility rules. A worker in California might receive SDI while waiting for an SSDI decision — or receive both at the same time, though offset rules can apply.
California SDI pays 60 to 70 percent of your weekly wages, based on what you earned during a 12-month base period prior to your disability. Workers with lower incomes receive the higher 70% rate; higher earners receive closer to 60%.
The weekly benefit cap adjusts annually. For recent years it has been roughly $1,500–$1,600 per week at the upper end, but that ceiling changes with California wage data — so the current maximum should be confirmed directly with EDD when you file.
Your base period is typically the 12 months ending five to eighteen months before your claim start date. EDD looks at your highest-earning quarter within that window to calculate your benefit rate. Workers who were recently employed with steady wages tend to receive higher weekly amounts; workers with gaps, part-time employment, or self-employment income (which isn't covered under SDI unless you opted into Elective Coverage) may receive less or may not qualify at all.
SSDI benefit amounts work on an entirely different formula. The SSA calculates your Primary Insurance Amount (PIA) based on your Average Indexed Monthly Earnings (AIME) — essentially a weighted average of your inflation-adjusted earnings over your working life.
The more years you worked and the higher your earnings, the higher your SSDI benefit. The SSA applies a bend-point formula that replaces a higher percentage of income for lower earners, and a lower percentage for higher earners — making SSDI modestly progressive.
Current averages: As of recent years, the average SSDI payment runs roughly $1,200–$1,600 per month, but individual benefits range widely — from below $700 to above $3,800 monthly. These figures adjust each year through Cost-of-Living Adjustments (COLAs). When citing any specific dollar figure from a search result, verify it reflects the current year.
Several variables shape what either program pays a specific person:
For EDD SDI:
For Federal SSDI:
Yes — and many Californians do, at least temporarily. SDI is a short-term benefit (up to 52 weeks), while SSDI has a five-month waiting period before the first payment and then continues long-term for qualifying disabilities. A person who applies for SSDI shortly after becoming disabled might receive SDI for months while awaiting an SSDI decision.
However, offsets apply. If you're receiving SDI and SSDI simultaneously, the SSA may reduce your SSDI payment so that the combined total doesn't exceed 80% of your pre-disability earnings. The interaction between the two can meaningfully affect your net monthly income during overlap periods.
Once SDI ends, SSDI continues for as long as your disabling condition meets SSA's definition of disability — a much stricter standard than California's SDI definition.
Neither program replaces your full income. SDI replaces a portion of wages for up to a year. SSDI replaces a portion of your career earnings, not your current wages. Both programs have gaps:
The numbers in this article describe how the programs are structured — not what you'd personally receive. Your EDD SDI benefit depends on your specific base period earnings. Your SSDI benefit depends on a calculation the SSA runs against your actual lifetime earnings record. Both figures exist in your SSA and EDD files — but neither can be estimated accurately without them.
