Michigan Jail Credit Calculator

A fast workflow for Michigan defense attorneys to document jail credit under MCL 769.11b. For each pre-sentencing custody stint, decide whether it earns credit, attach an optional reason in your own words, and download a PDF breakdown for sentencing. The legal classification is yours; the tool documents the math. No backend, no account; everything runs in your browser.

How this tool works

Workflow. Enter case information, then add a stint for each continuous period of custody. For each stint, toggle Earns credit or No credit and (optionally) describe the reason in your own words.

What the tool does. Counts days inclusive on both endpoints (booking day and release day both count; same-day = 1 day), per Michigan jail booking practice. Sums credit days across stints, counting a day shared by two stints (e.g. a cross-jurisdiction transfer date) only once, and renders a PDF breakdown with each stint's dates, day count, and reason.

What the tool does not do. Earned credit (good time), projected release date, and federal jail credit are out of scope. The tool documents your per-stint classification — it does not enforce Michigan doctrine or substitute for your legal judgment.

Privacy.Case data — defendant name, case number, custody dates — stays in your browser. There is no server-side storage and no third-party analytics beyond Cloudflare's privacy-preserving aggregate counts. Add a stint below to begin.
