1. What is the SDI Formula?

The SDI (State Disability Insurance) formula calculates disability insurance payments based on income after deductions and a specified rate. It's used to determine benefit amounts for eligible workers.

2. How Does the Calculator Work?

The calculator uses the SDI equation:

Where:

• \( Income \) — Gross income before deductions ($)
• \( Deductions \) — Eligible deductions from income ($)
• \( Rate \) — SDI rate as a percentage (%)

Explanation: The equation calculates the SDI payment by applying the rate to the net income after allowable deductions.

3. Importance of SDI Calculation

Details: Accurate SDI calculation helps employees understand their potential disability benefits and helps employers properly withhold and report SDI taxes.

4. Using the Calculator

Tips: Enter income in dollars, deductions in dollars, and rate as a percentage. All values must be valid (non-negative numbers, rate between 0-100%).
