An ankle monitor typically costs between $150 and $500 per month, and in almost every state the person wearing it pays the bill. The exact figure depends on the type of device the court orders, the private company handling the monitoring, and the county or state where you live. On top of the monthly charge, expect a one-time setup fee and potential liability for the device itself if anything happens to it.
The federal system is the main exception to offender-funded monitoring. The U.S. government covers monitoring costs for people in the federal criminal justice system and for immigrants supervised by Immigration and Customs Enforcement.1United States Courts. Federal Location Monitoring At the state and local level, the cost lands on you. A nationwide survey found that virtually every state requires monitored individuals to cover at least part of the cost of GPS monitoring. Some courts have contract provisions allowing indigent defendants to be placed on monitors at no charge, but judges rarely invoke those waivers in practice.
What the Monthly Bill Looks Like by Device Type
The single biggest factor in your monthly cost is what kind of monitor the court orders. There are three main categories, and the gap between them is wide.
GPS Monitors
GPS units track your location in real time and are the most common option courts order. Daily fees usually run $5 to $15, which puts the monthly total between roughly $150 and $450. Some jurisdictions and providers charge considerably more, with daily rates reported as high as $40, pushing monthly costs well past $500. Rates tend to be lower in larger urban areas with multiple competing vendors and higher in rural counties served by a single company.
Radio Frequency Monitors
RF monitors are the older, simpler technology. Rather than tracking your exact location, an RF unit confirms whether you’re within range of a base station in your home, which makes them best suited to house arrest or curfew enforcement. Daily rates typically run $1 to $5, so the monthly cost is roughly $30 to $150. Some RF systems still rely on a landline phone connection, meaning you may need to keep a landline at your own expense.
SCRAM Alcohol Monitors
SCRAM devices continuously test the sweat vapor on your skin for alcohol and are the priciest standard option. Daily rates generally fall between $10 and $12, translating to roughly $300 to $360 per month. Sliding-scale fee structures in some jurisdictions push higher earners to $24 per day or more, which can mean monthly bills approaching $730. Installation and removal typically add a flat fee of $50 to $170, and each detected violation or tampering event can trigger an additional charge of $100 or more. If the court orders SCRAM alongside a separate GPS monitor, you pay for both.
Setup Fees and Deposits
Expect a one-time charge at the start of monitoring. Setup or installation fees cover activating the device, fitting the strap, configuring any home base unit, and enrolling you in the monitoring system. These fees range from $25 to $300 depending on the provider and equipment. A basic RF installation lands on the low end; a GPS or SCRAM setup with additional calibration runs higher.
Some providers also require a refundable equipment deposit that’s separate from the installation fee. The deposit is generally returned when you turn in an undamaged monitor at the end of your term. If money is tight, ask the court or the monitoring company whether the deposit can be waived or reduced. Not every provider offers that flexibility, but it’s worth asking.
What You Owe If the Device Is Damaged or Lost
You are financially responsible for the equipment strapped to your ankle. Replacement bills reach roughly $800 for a standard GPS unit and upward of $900 for a SCRAM device, based on government procurement contracts. Your provider’s figures may differ, but the range is consistent. Even a replacement strap or charging cradle can run $30 or more.
This is where people get blindsided. A monitor damaged in a workplace accident, soaked in a flood, or stolen during a break-in is still your financial responsibility. Many monitoring agreements require you to report damage immediately, and delayed reporting can bring additional penalties. If you work in a physically demanding job, raise that concern with your attorney before the court finalizes monitoring conditions.
Costs That Don’t Show Up on the Invoice
The monthly fee and setup charge aren’t the only expenses. Several less obvious costs add up:
- Charging time. GPS monitors need to be charged regularly, often every 12 hours or so. You spend time tethered to an outlet, which can disrupt work, sleep, and daily routines.
- Phone and data. Some newer monitoring systems use a smartphone app alongside or instead of a physical device. You’ll need a compatible phone and a data plan that can handle continuous location reporting, and those costs come out of your pocket.
- Transaction fees. Many monitoring companies route payments through online portals or kiosks that add processing fees. Credit card surcharges of up to 10% and flat cash-payment fees of $2 or more per transaction are common, and they add up quickly on weekly or biweekly payments.
- Lost wages. The device itself limits job options. Some employers won’t hire someone wearing a visible monitor, and charging schedules can conflict with shift work. That doesn’t appear as a line item, but it’s a real cost.
If You Can’t Afford the Fees
You have a constitutional protection here. In Bearden v. Georgia, the U.S. Supreme Court held that courts cannot revoke someone’s probation or conditional release solely because they’re too poor to pay.2Justia US Supreme Court. Bearden v Georgia, 461 US 660 (1983) Before penalizing you for nonpayment, the court must first determine whether the failure was willful or the product of genuine financial hardship.
You can ask the court to reduce or waive monitoring fees. The process varies by jurisdiction, but you’ll usually need to document financial hardship with proof of public assistance, recent pay stubs or tax returns, a list of monthly expenses, and information about household size and dependents. Some states have formal indigency standards written into statute; others leave the determination to the judge. Either way, the burden is on you to raise the issue and provide evidence. Courts don’t proactively check whether you can afford what they impose.
A few practical points. Raise the request as early as you can, ideally at the hearing where monitoring is first ordered. If your finances get worse after monitoring begins, file a motion to modify. Keep records of every payment you do make, because good-faith effort carries real weight if nonpayment becomes an issue. And don’t just stop paying and go quiet. That is the fastest route to a warrant.
What Happens If You Fall Behind
Nonpayment is treated as a breach of your release or supervision conditions, and the consequences stack:
- Extended monitoring. The court adds time to your term, which increases the total cost.
- Tighter supervision. You may be moved from RF to GPS, or from standard GPS to a more restrictive program. Both cost more.
- Late fees and penalties. Late-payment surcharges, collection fees, or contempt fines pile onto the existing debt.
- Warrant and arrest. Some jurisdictions will issue a bench warrant for defaulted payments.
- Incarceration. The most severe outcome is jail time, which defeats the point of community monitoring in the first place.
Bearden’s protection applies here as well: a court must distinguish between someone who refuses to pay and someone who cannot pay before imposing jail time.2Justia US Supreme Court. Bearden v Georgia, 461 US 660 (1983) If you’ve made genuine efforts to find work and pay what you can, the court is required to consider alternatives. But you have to appear, explain your situation, and show the effort. People who simply stop paying and stop communicating get treated as willful non-payers even when they’re broke.
Unpaid monitoring fees can also outlast the criminal case. Some monitoring companies refer delinquent accounts to private collection agencies, which may report the debt to credit bureaus. A collection account is a derogatory mark that can sit on your credit report for seven years whether or not you eventually pay it. The company’s contract with the court may also allow it to pursue a civil judgment for the unpaid balance.
