How a Church Workers Comp Experience Mod Is Calculated
Once a church has enough payroll to qualify, workers compensation stops being a flat rate and starts being a calculation. The experience modification factor, usually just called the mod, is a multiplier applied to your manual premium. A mod of 1.00 is average. A mod of 0.85 means you pay fifteen percent less than an average employer of your size and type. A mod of 1.20 means you pay twenty percent more.
Churches with twenty or more employees are frequently rated this way and have never been shown the worksheet.
What goes into it
The mod compares your actual losses against the losses expected for an employer with your payroll in your classifications. It uses a three year window, and it excludes the most recent policy year, so the data is always somewhat historical.
| Input | What it means |
|---|---|
| Payroll by class code | Determines expected losses. Clergy, office, maintenance and teaching staff carry different rates |
| Actual losses, 3 years | Claims paid plus reserves still open. Open reserves count at full value even if the claim later settles for less |
| Expected losses | What an average employer of your size and mix would be expected to incur |
| Primary vs excess split | The first portion of each claim is weighted far more heavily than the rest |
Frequency hurts more than severity
This is the part that surprises church administrators. The formula weights the first several thousand dollars of each claim at full value and discounts the remainder. The practical effect is that five small claims damage a mod considerably more than one large one of the same total value.
For a church that means the slip in the parking lot, the volunteer who strained a back moving chairs and the kitchen burn matter more to your premium than their dollar amounts suggest. Reporting culture and early medical management are worth real money.

Open reserves are a quiet problem
A claim that is still open carries its reserve into the calculation at full value. If a carrier set a reserve high three years ago and the claim eventually closed for a fraction of it, your mod has been carrying the inflated figure the whole time.
Reviewing open claims before the mod is calculated, and pushing to close or re reserve the ones that are stale, is one of the few levers available in the short term. It requires asking, and most churches never ask.
What a church can actually change
Correct your class codes, because misclassified payroll inflates expected losses in the wrong direction and distorts everything downstream. Review open reserves annually. Build a return to work path so an injured employee comes back on light duty rather than accruing indemnity. Report incidents promptly, since late reporting raises claim cost measurably. And give the maintenance and facilities staff genuine attention, because that is where church claims concentrate.
Questions church administrators ask
Do we even have a mod?
You qualify once your premium exceeds a state specific threshold, generally reached by churches with roughly twenty or more employees. Ask your broker directly, and ask for the worksheet rather than the number.
Can a new carrier give us a better mod?
No. The mod follows the employer, not the carrier, and is produced by the rating bureau. Shopping changes the rate it multiplies, not the multiplier.
How long does an improvement take to show?
Because the calculation lags and excludes the most recent year, changes made today begin appearing in roughly eighteen months to two years. That is a reason to start, not a reason to wait.
Do volunteers affect it?
Volunteers are not payroll and do not generate premium, but a volunteer injury can become a claim depending on state law and your policy, and a claim does affect the mod. This is worth confirming specifically in your state.
