IHSS Hours Calculator
How a county works out your monthly IHSS hours — the Functional Index ranks, the published task-time ranges, and why nobody can give you a real figure before an assessment.
Why there is no honest one-click calculator
The CDSS Hourly Task Guidelines contain twelve task grids. Any short quiz can only ask about a handful of them — and the ones left out are the heaviest. Feeding runs to 9.33 hours a week on its own; bowel and bladder care to 8.00. A four-question tool tops out at roughly 37% of the personal-care time a real assessment scores, and it under-reads worst for the people who need the most help.
So this page explains the calculation instead of faking it. If you want the number for your own situation, that takes the full task-by-task walkthrough — the Clarity Report does it across every scored category.
Educational information, not an authorization. Only your county can authorize IHSS hours, and only after an in-home assessment.
How IHSS hours are actually calculated
Your hours are not a single judgement call. A county social worker visits your home and scores each task separately, and those scores drive a published range of minutes. Four things decide the number.
1. Your Functional Index rank for each task. Every assessed task gets a rank from 1 to 5 describing how much help you need — 1 is fully independent, 5 means the task is done entirely by someone else. Rank 1 generates no time at all, which is why the calculator above ignores it. The rank-by-rank guide explains where the line falls between each one, which is usually where hours are won or lost.
2. The Hourly Task Guidelines for that rank. CDSS publishes a weekly time range for each task at each rank. The social worker picks a figure inside that range based on your circumstances. These are the ranges the calculator above uses:
| Task | Rank 2 | Rank 3 | Rank 4 | Rank 5 |
|---|---|---|---|---|
| Loading the published ranges… | ||||
3. How often you need the help. A task needed daily produces far more time than the same task needed twice a week, even at the same rank.
4. What else is assessed. The four grids above cover some personal care and meals. A real assessment also scores mobility transfers, toileting, laundry, shopping, housework, paramedical services such as injections or wound care, and Protective Supervision for someone who cannot be left alone safely. This is why a genuine authorization is usually far higher than any short online estimate.
Why the estimate is a range, not a number
The guidelines themselves are ranges, so two people with identical ranks can be authorized different hours. Counties also vary in how they apply them, and there are statewide monthly ceilings — 283 hours for severely impaired recipients, 195 otherwise — that cap the total regardless of what the task-by-task maths produces.
Anyone promising an exact figure before an assessment is guessing. What you can do is arrive understanding how the scoring works, so the assessment reflects a normal day rather than your best one.
What to do next
If you have not applied yet, IHSS applications are taken by phone through your county office — there is no statewide online application. Find your county's IHSS number. To see how your county compares on hours and wages, the county data table has all 58. If you are preparing for an assessment, the Applicant Hub covers what to expect and what to have ready. If your hours were already set and you think they are too low, appeal deadlines are short — usually 90 days from the Notice of Action.
