Stop Ignoring Your Mod Worksheet — Start Using It

Every year, employers receive a document that has a direct impact on their workers’ compensation costs. Most glance at it briefly—if at all—and file it away. That document is your experience mod worksheet. And ignoring it is one of the biggest missed opportunities in cost control.

What the Worksheet Actually Shows

Your mod worksheet breaks down how your experience modification factor is calculated.

At its core, it answers one simple question:

How do your actual losses compare to what was expected?

But instead of one number, it shows the components behind that comparison, including:

• Actual losses
• Expected losses
• Primary vs. excess losses
• Stabilizing values
• Final mod calculation

It’s not just a report but a roadmap.

The Most Important Concept: Actual vs. Expected

If you take only one thing from your worksheet, it should be this:

Your mod is driven by actual losses versus expected losses.

• If your actual losses are higher than expected → your mod increases
• If your actual losses are lower than expected → your mod decreases

Everything else in the worksheet supports this relationship.

Why Most Employers Miss the Value

The worksheet looks complex. There are columns, formulas, and unfamiliar terminology.

So most employers do one of two things:

• Ignore it
• Rely entirely on their broker or carrier to interpret it

But that creates a problem: If you don’t understand what’s driving your mod, you can’t control it.

What You Should Actually Look For

Instead of getting lost in the math, focus on relationships:

1. Actual vs. Expected Totals

Are your losses higher or lower than expected?

2. Primary Losses

How much of your losses fall under the primary threshold (around $17,000)? This is where frequency shows up—and where most of your mod impact comes from.

3. Trends Over Time

Are your numbers improving or getting worse?

Turning the Worksheet Into a Strategy Tool

When you understand your worksheet, you can start asking better questions:

• Why are our primary losses high?
• Are we seeing too many small claims?
• Are we converting medical-only claims into lost-time claims?
• Are delays in reporting increasing claim costs?

Now the worksheet becomes actionable.

Why This Matters for Leadership

Executives don’t need to understand the full formula.

But they do need to understand:

• Where the costs are coming from
• What is controllable
• What actions will reduce those costs

The worksheet provides that visibility if you know where to look.

Final Thought

Your mod worksheet isn’t just paperwork. It’s one of the most valuable tools you have to understand and reduce your workers’ comp costs. If you’re not reviewing it regularly, you’re operating without visibility. And in workers’ compensation, what you don’t see is usually what costs you the most.
