Where do the rates come from?

Every SAWW, minimum, and maximum figure comes from the Minnesota Department of Labor & Industry annual adjustment tables, keyed to the effective date. Formulas come from Minn. Stat. ch. 176 and Minn. R. ch. 5223, cited on each page.

How often do Minnesota workers’ comp rates change?

Most October 1sts. The SAWW resets each year, which moves the maximum rate (108% of SAWW for injuries on or after October 1, 2024), the minimum, and the PTD floor (65% of SAWW). Your date of injury controls which table row applies to you.

How do you know the calculators have not drifted?

A golden-master test suite pins the exact output of every calculator across hundreds of scenarios, so a code change that alters a stored dollar figure fails the tests and has to be explained. Rate updates also fail the tests unless the explanatory prose is updated to match.

What do the calculators NOT decide?

They do not decide whether your injury is compensable, what your correct AWW method is in a dispute, what a fair settlement is, or whether an insurer’s denial is right. They compute what the statute says the numbers should be if the inputs are right.

Who checks the legal claims?

The math and the plain-English explanations are reviewed by Daniel C. Swenson, Minnesota workers’ compensation attorney at Robert Wilson & Associates. See the editorial policy and the About page for more on who is behind the site.

How we keep the math current

The rates come from DLI tables, the formulas from cited statutes, and the calculators are pinned by automated tests. This page explains how, and links the sources, so you (or your lawyer, or your adjuster) can verify rather than trust.

Where the numbers come from

Rates:the Minnesota Department of Labor & Industry's annual adjustment and rate tables, stored in the engine as one table row per effective date back to 1992. We archive the source PDF on this site so the figures stay verifiable even if DLI reorganizes its pages.
Formulas: Minn. Stat. ch. 176 and Minn. R. ch. 5223. Each calculator page cites the specific subdivision it implements, and the sources page collects every citation in one place.
Date-of-injury logic:Minnesota benefits are controlled by the law and rate table in effect on your date of injury, not today's. The engine picks the correct historical row automatically, including the pre- and post-October 2024 maximum-rate formulas and the escalation rules that vary by injury era.

How drift is prevented

The calculators share one calculation engine, and that engine is pinned by a golden-master test suite: hundreds of input scenarios whose exact outputs are stored as fixtures. A code change that moves one of those outputs fails the test suite, which forces a review of why the number changed before the change ships.

Separate statute-cited testsassert specific legal rules (for example, the PTD minimum of 65% of SAWW under Minn. Stat. § 176.101, subd. 4, or the 500%-of-SAWW combined cap on TPD) with the citation in the test itself, so a future edit cannot quietly reinterpret the law.

Rate-prose drift guards fail the build if the October rate table is updated without updating the written explanations that quote those numbers, so the prose and the table are checked against each other rather than maintained by memory.

The public calculation API calls the same engine functions as the on-page calculators, so API results and UI results cannot disagree.

Recent and upcoming rate changes

October 1, 2025

New DLI table: SAWW $1,423.00, maximum rate $1,536.84, minimum $307.37, annual adjustment 3.72%. All calculators and rate pages updated the same cycle.

October 1, 2024

The maximum compensation rate formula changed from 102% to 108% of the SAWW for injuries on or after this date (max jumped to $1,481.76 on a $1,372.00 SAWW).

October 1, 2026 (upcoming)

DLI will publish the next SAWW and weekly benefit table. The PPD Chapter 103 schedule for this date is already in the engine; when DLI publishes the SAWW row, comp-rates.json, golden-master fixtures, and this page are updated together.

The full history is on the rate & law updates log and the rate tables.

What the calculators do not decide

The tools compute what the statute says the numbers should be, assuming your inputs are right. They do not decide whether your injury is compensable, which AWW method a judge would use in a dispute, whether an insurer's denial holds up, or what a fair settlement is for your specific claim. Those are judgment calls, and the claim checkup can help you figure out whether yours is the kind of situation where talking to a lawyer is worth it.
