How do you calculate return-to-work savings?

Subtract the without-program cost from the cost avoided with the program to get the net margin. With 125 avoided and 100 without-program cost, the margin is 125 - 100 = 25.

What is a good return-to-work savings margin?

Any positive margin means the program pays for itself; the larger the gap between avoided cost and do-nothing cost, the stronger the case. Our example shows a 25-unit margin, meaning the program returns more than the claim would have cost.

What is the reference amount for?

It is a baseline injury cost you can anchor the comparison to, useful for normalizing the margin across claims of different sizes. It does not change the core margin calculation, which is avoided minus without-program cost.

Does this account for the cost of light duty?

Only if you net it out of the avoided-cost figure first. The calculator compares the two amounts you enter, so subtract any wage subsidy or accommodation cost before entering the avoided amount for an honest margin.

How does return-to-work lower total claim cost?

Bringing a worker back on modified duty cuts indemnity payments, shortens lost-time days, and often reduces the reserve on the claim, all of which show up as a larger avoided cost and thus a bigger margin.

Return to work savings vs claim cost reduction, what is the difference?

Claim cost reduction is the raw drop in a single claim. This margin compares that avoided cost against the do-nothing baseline, so it isolates the net value the program itself created.

Safety & Workforce calculator

Return to Work Savings Calculator

The Return to Work Savings calculator quantifies what a modified-duty or early return-to-work program saves versus letting an injured worker stay out on full disability. It compares the cost you avoid by bringing someone back on light duty against the cost the injury would otherwise carry, and reports the net margin. Risk managers, workers' comp coordinators, and EHS leaders use it to prove that RTW programs cut claim costs, shorten lost-time, and lower experience-mod. A positive margin is the number that keeps an accommodation program funded.

What this calculator does

Estimate savings from return-to-work program compared with lost time cost.
Use it when return to work savings in safety and workforce needs a clean margin number for a safety and workforce go / no-go review.
It computes the net margin between the cost avoided through a return-to-work program and the cost the injury would carry without it.

Formula used

Margin = gain or available amount - cost or required amount

Inputs explained

Cost avoided with a return-to-work program:
Cost of the injury without the program:
Baseline injury cost for reference:

How to use the result

Use it when evaluating or reporting on a return-to-work or modified-duty program and you need to show net savings against the do-nothing baseline.
It compares the two figures you supply; it does not model wage-subsidy costs, productivity of light duty, or the long-tail effect on your experience-mod unless you build those into the inputs.

Current U.S. benchmarks

Manufacturing hourly earnings average $30.27 (BLS, Jun 2026), up 4.4% from a year earlier. Median machinist pay is $28.24/hr (OEWS 2025), with state medians on each state page. Manufacturers have 529k open positions nationally (BLS JOLTS).
