What is an EDD SDI Calculator?
An EDD SDI calculator is a tool designed to estimate your potential weekly benefit payments from California’s State Disability Insurance (SDI) program. This program provides partial wage replacement benefits to eligible California workers who are unable to work due to a non-work-related illness, injury, or pregnancy. Our calculator uses the same core logic as the Employment Development Department (EDD) by analyzing your earnings during a specific “base period” to provide a reliable estimate. This helps you forecast your income and plan your finances during a period of disability.
EDD SDI Calculator Formula and Explanation
The California EDD determines your weekly benefit amount based on the wages you earned in a 12-month **base period**, which is approximately 5 to 18 months before your disability claim begins. The EDD identifies the calendar quarter within that base period where you had the highest earnings. Your weekly benefit is calculated as a percentage of those high-quarter earnings. For 2025, this rate is between 70-90%. The minimum weekly benefit is $50, and the maximum is $1,765.
The simplified formula is:
Weekly Benefit Amount = (Earnings in Highest Quarter ÷ 13 weeks) × Benefit Rate (70-90%)
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Base Period Earnings | Wages subject to SDI tax earned 5-18 months before your claim. | USD ($) | $300+ |
| Highest Quarter Earnings | The total earnings in the highest-paid calendar quarter of your base period. | USD ($) | Varies widely |
| Benefit Rate | The percentage of your wages that SDI replaces. | Percentage (%) | 70% to 90% |
| Weekly Benefit Amount (WBA) | The final estimated amount you receive per week. | USD ($) | $50 – $1,765 |
Practical Examples
Example 1: Standard Income
Let’s say your disability claim starts on June 15, 2026. Your base period would be January 1, 2025, to December 31, 2025. Suppose your quarterly earnings were:
- Q1 2025 (Jan-Mar): $12,000
- Q2 2025 (Apr-Jun): $13,500
- Q3 2025 (Jul-Sep): $13,000
- Q4 2025 (Oct-Dec): $12,800
The EDD would use your highest quarter, Q2 2025, with earnings of **$13,500**. The calculation would estimate your weekly benefit based on this amount, which would fall into the 70% replacement tier, providing a substantial weekly payment.
Example 2: Low or Inconsistent Income
Imagine your claim begins on February 20, 2026. The base period is October 1, 2024, to September 30, 2025. Your earnings were:
- Q4 2024 (Oct-Dec): $4,000
- Q1 2025 (Jan-Mar): $2,500
- Q2 2025 (Apr-Jun): $800
- Q3 2025 (Jul-Sep): $4,200
Here, the highest quarter is Q3 2025 with **$4,200** in earnings. Because this income is lower, the benefit rate applied might be closer to 90%, ensuring you still receive critical support. To be eligible, you must have earned at least $300 in one base period quarter.

Key Factors That Affect SDI Benefits
- Earnings History: The amount of your benefit is directly tied to how much you earned in your base period. Higher earnings lead to a higher benefit, up to the legal maximum.
- Claim Start Date: This date is crucial as it locks in your 12-month base period. Filing in a different month can shift the base period, potentially changing which earnings are considered.
- Benefit Rate Percentage: California uses a progressive system. Lower-income earners receive a higher percentage (up to 90%) of their wages, while higher earners receive a lower percentage (around 70%).
- Maximum Weekly Benefit: The state sets a maximum weekly benefit amount each year. For 2025, this amount is $1,765. Even if your earnings are very high, you cannot receive more than this weekly cap.
- Eligibility Requirements: You must have earned at least $300 in your base period and have paid into the CASDI fund through payroll deductions to qualify.
- Part-Time Work: If you return to work part-time while on SDI, your benefits may be reduced. The EDD calculates your “wage loss” to determine your partial benefit.
