How Workers' Comp Is Calculated in Minnesota

Minnesota workers' compensation benefits are not one flat number - they are calculated differently depending on the type of benefit. Understanding the formulas matters because the insurer's initial calculation is not always right, and you have the right to verify it.

This guide walks through each major benefit type: how the number is determined, which statute controls, and where you can run your own calculation.

If you have a specific question, consider talking to a workers' comp attorney about your specific situation.

Step 1: Your Average Weekly Wage (AWW)

Every wage-loss calculation in Minnesota workers' comp starts with your Average Weekly Wage (AWW).

Under Minn. Stat. § 176.011, subd. 18, your AWW is typically calculated from your earnings during the 26 weeks before your date of injury. The statute accounts for several situations:

• Steady employment with one employer. Add up gross wages for the 26 weeks preceding the injury and divide by the number of weeks actually worked.
• Concurrent employment. Wages from all employers at the time of injury may be combined.
• Irregular or seasonal employment. The calculation may use a longer lookback or alternative method to produce a "fair approximation" of your earning capacity.
• Fringe benefits. Certain fringe benefits (health insurance contributions, for example) can be included in AWW under specific circumstances.

Getting the AWW right is critical because every other wage-loss number flows from it.

Use the AWW calculator to estimate yours. Enter your wages and it will compute the figure used in subsequent benefit formulas.

Step 2: Temporary Total Disability (TTD)

TTD is the weekly wage-replacement benefit for workers who cannot work at all because of their injury.

The formula under Minn. Stat. § 176.101, subd. 1 is:

TTD rate = ⅔ × AWW (subject to statewide maximum and minimum)

Key rules:

• Maximum rate. If two-thirds of your AWW exceeds the statutory maximum, you receive the maximum. The maximum changes every October 1 based on the Statewide Average Weekly Wage (SAWW) published by the Department of Labor and Industry (DLI).
• Minimum rate. If two-thirds of your AWW is below the statutory minimum, you receive the minimum - or your full AWW, whichever is less.
• Date of injury controls. The max/min that applies to your claim is determined by your date of injury, not the date you start receiving payments.
• Tax-free. TTD benefits are generally not subject to state or federal income tax.

Example: If your AWW is $1,200 and the maximum for your DOI period is $1,259.28, then ⅔ × $1,200 = $800 per week - below the cap, so your TTD rate is $800.

Use the TTD calculator to compute your exact rate for any date of injury.

Step 3: Temporary Partial Disability (TPD)

TPD is the wage-loss benefit for workers who can work but earn less because of their injury - for example, working part-time or in a lower-paying light-duty position.

The formula under Minn. Stat. § 176.101, subd. 2 is:

TPD rate = ⅔ × (AWW − current weekly earnings)

In other words, you receive two-thirds of the difference between what you were earning before and what you are earning now.

Key rules:

• Same max/min framework as TTD. TPD is subject to the same statewide caps.
• Earnings fluctuate. If your current earnings change week to week (common with light duty), the TPD amount changes too.
• Incentive built in. Because you keep one-third of the wage difference plus your actual earnings, returning to partial work always puts more money in your pocket than staying home on TTD - assuming the work is within your restrictions.

Use the TPD calculator to see how much you would receive at different earning levels.

Step 4: Permanent Partial Disability (PPD)

PPD is fundamentally different from TTD and TPD. It is not based on lost wages. Instead, it compensates you for the permanent functional loss to a body part.

PPD is governed by Minn. R. 5223 (the Minnesota Disability Schedule). Here's how it works:

1. A doctor assigns a permanency rating. After you reach Maximum Medical Improvement (MMI), your treating doctor or an IME doctor will rate your permanent impairment as a percentage.
2. The rating maps to a schedule. Rule 5223 assigns a specific number of "weeks of compensation" to each body part and impairment level. For example, a 10% disability of the whole body corresponds to a different number of weeks than a 10% disability of a shoulder.
3. Weeks × compensation rate = PPD lump sum. The number of weeks from the schedule is multiplied by a per-week dollar amount set by statute (which also depends on date of injury).

Key points about PPD:

• You can receive PPD even if you returned to full wages. PPD is about permanent physical impairment, not wage loss.
• PPD is usually paid as a lump sum once the rating is established and accepted.
• Multiple ratings can combine. If you have injuries to more than one body part, the ratings are combined using a statutory formula (not simple addition).
• Weber-based ratings are used for certain conditions. These involve converting a whole-body percentage to an equivalent schedule-based value.

Use the PPD calculator to look up the schedule value for your body part and impairment rating.

Step 5: Permanent Total Disability (PTD)

PTD is the most significant wage-loss benefit. It applies when your injury permanently and totally prevents you from working in any capacity for which there is a reasonably stable labor market.

Under Minn. Stat. § 176.101, subd. 4:

PTD rate = ⅔ × AWW (subject to the same max/min as TTD)

The weekly rate formula is the same as TTD, but PTD continues for the duration of the disability - which can be the rest of your life. There is no arbitrary cutoff.

PTD is relatively rare and almost always contested by insurers. Establishing PTD typically requires:

• a strong medical foundation showing you cannot perform any suitable work,
• vocational evidence (often a vocational expert opinion) that no jobs are available within your restrictions,
• and usually a hearing before a compensation judge at the Office of Administrative Hearings (OAH).

Step 6: Death and Dependency Benefits

When a work injury results in death, Minnesota provides benefits to the deceased worker's dependents under Minn. Stat. § 176.111.

• Wholly dependent spouse receives weekly benefits similar in structure to TTD/PTD.
• Dependent children may receive additional benefits.
• Burial expenses are covered up to a statutory limit.
• No dependents - if the deceased worker has no dependents, the employer/insurer pays a lesser amount to a special state fund.

The exact amounts and durations depend on the date of injury and the dependency status of survivors. These cases are complex and almost always require legal representation.

How the Pieces Fit Together

Not every injured worker receives every type of benefit. Here's a typical timeline:

1. Injury occurs. AWW is established based on pre-injury earnings.
2. Off work entirely. TTD begins (⅔ of AWW).
3. Return to light duty at reduced pay. TTD stops; TPD begins (⅔ of wage difference).
4. Reach MMI. Doctor assigns a permanency rating. PPD is calculated and paid (lump sum).
5. Full return to work. Wage-loss benefits end, but PPD is unaffected.
6. Cannot return to any work ever. PTD may apply (ongoing ⅔ of AWW).

The transition points - especially between TTD and TPD, and the timing of MMI - are where disputes most commonly arise.

Common Mistakes in Benefit Calculations

Benefit calculations are not always done correctly. Watch for these issues:

• AWW computed from the wrong time period. The insurer should use the 26 weeks before injury, but sometimes they use a shorter or different window.
• Fringe benefits excluded. If your employer paid for health insurance or other qualifying fringe benefits, those may increase your AWW.
• Wrong max/min rate applied. The cap is determined by date of injury, not date of payment. Using the wrong year's rate table is a common error.
• PPD schedule lookup error. The disability schedule is complex. Body part categorization and percentage-to-weeks conversion must follow Rule 5223 precisely.
• Concurrent employment omitted. If you held two jobs at the time of injury, wages from both should be included in AWW.

If something looks wrong, run the numbers yourself using the calculators on this site, and consider getting legal advice.

Frequently Asked Questions

How is workers' comp calculated in Minnesota?

It depends on the benefit type. The starting point is always your Average Weekly Wage (AWW), calculated under Minn. Stat. § 176.011, subd. 18. TTD pays two-thirds of AWW (with statutory caps). TPD pays two-thirds of the wage difference. PPD is a scheduled lump sum under Rule 5223 based on impairment, not wages. PTD uses the same formula as TTD but continues for the duration of disability.

What is the maximum workers' comp rate in Minnesota?

The maximum weekly rate changes every October 1, pegged to the Statewide Average Weekly Wage (SAWW) published by DLI. It applies to TTD, TPD, and PTD. Use the TTD calculator on this site to find the exact cap for any date of injury.

Does workers' comp pay 100% of my wages?

No. Wage-loss benefits (TTD, TPD, PTD) pay two-thirds (66⅔%) of the applicable wage figure, not 100%. The benefit is also subject to statutory maximums and minimums that depend on your date of injury.

Is PPD based on lost wages?

No. Permanent Partial Disability is a scheduled benefit calculated under Minn. R. 5223. It is based on the body part injured and the percentage of impairment rated by a doctor at MMI. You can receive PPD even if you returned to full wages with no earnings loss.
