Free California calculators and tools
Free calculators built from official California rules: unemployment and SDI/PFL benefit estimates, employer payroll taxes and DBA filing deadlines.
Each tool runs entirely in your browser, uses the rules and rates published by the official agency, and shows its method and sources on the page. Nothing you type is stored or sent anywhere.
| Tool | What it does | Based on |
|---|---|---|
| Unemployment benefit calculator | Finds your base period, checks EDD's wage minimums, and estimates your weekly benefit, claim maximum and part-time pay | EDD benefit table (DE 2320) |
| SDI and Paid Family Leave calculator | Estimates your 2026 weekly benefit for disability or family leave | EDD 2026 benefit brackets |
| Employer payroll tax calculator | Works out UI, ETT and SDI for each employee | EDD 2026 rates (DE 44) |
| DBA deadline calculator | Gives your filing, newspaper publication, affidavit and renewal dates | Bus. & Prof. Code §§17910–17920 |
How we build our tools
- Official rules only. Every formula, rate and table comes from the agency's own publication, linked on the tool's page.
- Tested against official examples. We check each calculator against the agency's published table rows and worked examples before publishing.
- Updated every January. Benefit caps and tax rates change each year; each tool shows the year it applies to.
- Estimates, not decisions. Only the agency can determine your eligibility or official amount.
