RateString turns WPI into a defensible permanent-disability rating — the DEU rating string, Combined Values, apportionment, and indemnity — recalculating live as you type.
No Calculate button, no reload. Every keystroke reflows the rating string, the Combined Values, and the dollar figures.
SB 863 1.4×, occupational and age tables from the official PDRS, the Combined Values Chart, §4663 apportionment, the pain add-on, and the single-extremity cap.
Every rating reads back as the DEU string with a step-by-step, traceable breakdown — the part that makes it defensible.
Statutory weekly-rate caps and PD-weeks brackets are versioned by year, so a rating is never run on a stale table.
The calculator is free. You pay only when you want to save, organize, and export your work.
