California SDI Calculator
California employees often see SDI deductions on their paychecks, but many people do not fully understand how this amount is calculated. The deduction depends on your wages, pay frequency, SDI tax rate, and the annual wage limit set by the state. Manually calculating these values can be confusing and time-consuming.
The California SDI Calculator is a simple and reliable tool that helps you calculate your SDI deduction per paycheck, net pay, annual SDI contribution, and maximum SDI limit within seconds. Whether you are paid weekly, monthly, or annually, this calculator gives you clear and accurate results.
This tool is especially useful for employees, payroll staff, freelancers, and anyone working in California who wants transparency in their paycheck deductions.
What Is California SDI?
SDI stands for State Disability Insurance. It is a mandatory payroll deduction in California that provides partial wage replacement if an employee is unable to work due to:
- Non-work-related illness or injury
- Pregnancy and childbirth
- Caring for a seriously ill family member
- Bonding with a new child
Employees contribute a percentage of their wages up to a maximum annual wage limit. Once that limit is reached, SDI deductions stop for the year.

Understanding the Results
SDI Deduction
This is the amount deducted from your paycheck for State Disability Insurance.
Net Pay
Your take-home pay after SDI deduction (before other taxes).
Annual SDI
The total amount you will pay in SDI contributions for the year.
Annual Wages
Your estimated total earnings for the year based on your pay frequency.

Why SDI Has a Wage Limit
California applies SDI only up to a certain wage amount. Once your earnings exceed the annual wage limit, SDI deductions stop for the rest of the year. This protects high-income earners from unlimited deductions while ensuring fair contributions.
