How Much Does Electronic Monitoring Cost? An Agency Pricing Guide

Rates vary substantially by region, by court, and by whether the participant or a public agency is paying, but the broad market shape is consistent. Active GPS ankle monitoring most commonly falls in the range of roughly $8 to $15 per day for participant-pay programs, sometimes higher in high-cost metros or for enhanced supervision with exclusion zones. Radio-frequency house arrest and curfew monitoring, which uses a home base station rather than continuous satellite tracking, typically runs lower — commonly $5 to $10 per day.

Continuous transdermal alcohol monitoring such as SCRAM is generally the most expensive category, frequently in the $10 to $15 per day range, reflecting higher device cost and the daily data review the technology requires. Remote breath alcohol devices with scheduled tests usually sit somewhat below continuous monitoring. Combination placements — GPS plus alcohol monitoring — are usually priced as the sum of both device fees, occasionally with a modest bundle discount.

On top of the daily rate, most agencies charge a one-time enrollment or installation fee, commonly somewhere between $50 and $200, and many hold an equipment deposit. Treat every number here as a market orientation, not a benchmark to copy — your own cost structure and your court agreements govern.

Break the rate into its parts and pricing decisions get much easier. Device amortization comes first: a GPS unit represents real capital, spread across its useful life and its expected utilization, which is never 100%. Then connectivity and platform charges — nearly every device vendor bills a per-unit monthly fee for the cellular data and monitoring portal, and that meter runs whether or not the unit is on a participant.

Labor is the component agencies chronically underestimate. Enrollment and fitting, alert triage, compliance reporting to courts, participant phone calls, equipment retrieval, cleaning and refurbishment between placements, and billing and collections all consume staff time per participant per month. Add loss and damage reserve — straps get cut, units get lost, participants abscond with equipment — and treat it as a normal cost of doing business rather than an exception.

Finally, payment processing and bad debt. Even a well-run participant-pay program does not collect 100% of billed fees. If your pricing assumes it does, your effective margin is materially lower than your spreadsheet says.

Add up your monthly fixed costs per active unit: amortized device cost, vendor platform and connectivity fee, and your loss reserve. Add your labor cost per participant per month based on an honest hours estimate. Add overhead — insurance, office, software, phones — divided across your expected active caseload. That total, divided by thirty, is your break-even daily rate at that caseload level.

Now apply two adjustments. Divide by your realistic collection rate: if you expect to collect 85% of what you bill, your billed rate needs to be roughly 18% above break-even just to reach break-even in cash. Then add your target margin. The result is usually higher than what new agencies instinctively charge, which is precisely the point.

Run the same model at different caseload sizes. Fixed platform costs mean your break-even daily rate drops significantly as utilization rises, which tells you where you can afford to be competitive on a large court contract and where you cannot.

Who pays changes everything about the economics. In participant-pay programs the collection rate is the dominant variable, and pricing must absorb both bad debt and the operational cost of collections. In agency-pay or county-contract programs you are typically billing a single reliable payer monthly, so collection risk nearly vanishes — but rates are usually set competitively through procurement and margins are thinner.

Many successful agencies run both: contract volume for baseline utilization that covers fixed platform costs, and participant-pay placements for margin. If you do, keep the two billing streams cleanly separated in your system so you can see the true profitability of each rather than a blended number that hides a losing contract.

The highest rate you can quote is not the highest revenue you can collect. A $15 daily rate billed monthly to an unemployed participant produces a $450 invoice that will not be paid and a balance that will never be recovered. The same participant billed $105 weekly often pays most weeks.

Two levers move collected revenue more than the headline rate: matching the billing cycle to the participant's income cadence, and making payment effortless with a link they can tap from a text. Our guides on recurring billing for monitoring clients and reducing late payments cover both in depth, and Tether Pay's billing software automates the mechanics.
