Every workers’ comp calculator, in one place.
Seventeen free tools, one engine — the same tables, the same math, verified against the DIR’s published worked examples and covered by an automated test suite. No account for any of them.
PD rating calculator
WPI in — the full 2005-schedule pipeline out: ×1.4, occupational variant, age, apportionment, CVC combination, and the DEU-format rating string with the dollars.
Open the calculator →Settlement calculator
Final PD % + wage + injury year → weeks of PD, the weekly rate, total indemnity, the life-pension line at 70%, and the attorney-fee estimate.
Price a rating →Life pension calculator
Ratings of 70–99% earn a second benefit for life. The §4659(a) formula computed on your PD %, wage, and injury year — the cap, the COLA rule, and when it starts.
Compute a life pension →WPI → PD calculator
The doctor’s impairment number is not the payable percentage. Convert WPI through the ×1.4, occupation, and age steps — live, with a reference table.
Convert a WPI →TD rate calculator
Temporary disability from AWW + injury year: the weekly rate against the statutory min/max, the biweekly check, and every year’s caps since 2013.
Compute a TD rate →AWW calculator
Every check starts from the average weekly wage. Enter pay in any period — hourly to annual — and get the AWW plus the TD and PD rates against the year’s statutory rails.
Compute an AWW →GAF → WPI calculator
The psychiatric conversion: a GAF score read against the exact PDRS p.1-16 table, then rated to PD — with the §4660.1(c) compensability limits explained.
Convert a GAF →Deadline calculator
The statutory dates every file tracks — the 90-day decision window, the earliest §5405 limitations date, the §5410 five-year window, the TD outer boundary — from a date of injury.
Run the clocks →PD money chart
Every percentage 1–99 converted to weeks and dollars for any injury year since 2005 — wage-personalized, printable, embeddable.
Open the chart →Rating-string decoder
Paste any DEU-style rating string. Every segment decoded and the math verified against the PDRS tables — including the implied age bracket.
Decode a string →Batch rating
CSV rows in — impairment, WPI, group, age, apportionment, year — engine-rated PD, weeks, dollars, and strings back for every claim at once.
Rate a list →Rate caps by year
The statutory PD and TD weekly minimums and maximums for every injury year 2005–2026, straight from the engine’s tables.
See the caps →Settlement chart
Sixteen injury families — back, fusion, knee, carpal tunnel, hearing, amputations, psych — priced across the occupational range at the current maximum, each linking a deep guide.
Open the chart →Combined values calculator
The CVC, computed: enter any number of impairment percentages and watch the schedule’s fold — largest first, rounded at each step — plus the reference chart and what the total is worth.
Combine ratings →SIBTF calculator
The Subsequent Injuries Fund doors, rewritten July 2026: WPI after apportionment against the 35% and 5% thresholds, the 70% combined floor, and the new filing deadline — checked in one pass.
Check a claim →Commutation calculator
The present value of a PD award at 3%, straight from the DWC’s own commutation table (CCR §10169, Table 1) — the discount every lump-sum and attorney-fee conversation is priced on.
Run the table →Award interest calculator
Unpaid WCAB awards accrue 10% per annum under §5800. Amount + dates in — the days, the daily interest, and the total due out, with the §4650(d) and §5814 distinctions explained.
Run the interest →Working a claims desk? The adjuster workflow page chains these into same-day reserves. New to ratings? Start with how PD is calculated. Estimates for informational use; verify against the DEU. Not legal advice.
