Most people on a home detention program pay between $5 and $15 a day for the monitoring device itself, but the full cost runs higher once setup fees, drug testing, counseling, and supervision charges are added in. Over a typical sentence, out-of-pocket totals range from a few hundred dollars to several thousand, depending on where you live, how long you’re monitored, and which device the court orders.
Daily Monitoring Fees by Device
The largest recurring charge is the daily fee for whatever device you’re assigned. Three types are common, and the price gap between them matters.
- Radio frequency (RF) monitors are the cheapest, generally $3 to $8 per day. They only confirm whether you’re inside your home.
- GPS tracking devices run $5 to $15 per day and track your movements continuously. Courts assign them when they want to verify a schedule or enforce exclusion zones.
- SCRAM alcohol monitoring bracelets, which test sweat for alcohol, cost roughly $10 to $15 per day. A single device combining SCRAM with GPS or house arrest tracking sits at the higher end of that range.
Those charges compound fast. At $10 a day, 90 days of monitoring costs $900 before anything else is added. Six months at the same rate is $1,800. A federal literature review puts the general range at $5.50 to $10.00 per day, though actual costs vary by provider and jurisdiction.1Office of Juvenile Justice and Delinquency Prevention.

Setup Fees and Equipment Responsibility
Most programs charge an installation or activation fee when the device is first attached, typically $50 to $200. Some jurisdictions waive it.
A cost that catches people off guard is the phone or internet requirement. Older RF systems may need a dedicated landline without call-waiting, caller ID, or three-way calling, which can mean paying for a separate line at your expense.1Office of Juvenile Justice and Delinquency Prevention. Home Confinement and Electronic Monitoring Literature Review Newer GPS units transmit over cellular networks and skip the landline issue, though that doesn’t necessarily lower the daily fee.
You’ll also sign an agreement making you financially responsible for the device. Lost, damaged, or tampered equipment can cost several hundred dollars to replace. Keeping the battery charged is on you as well. Most ankle monitors need one to two hours of daily charging, and letting the battery die counts as a program violation.
Other Required Costs Stacked On Top
The monitor is one line item. Courts routinely attach conditions that carry their own fees.
- Drug and alcohol testing. Urinalysis, breathalyzer, or hair follicle tests can run from a few dollars up to $85 each, depending on the type and lab. Multiple tests per month are common.
- Counseling and treatment. Substance abuse programs, anger management, or mental health counseling can cost $15 to $100 or more per session, and a multi-month program adds up quickly.
- Monthly supervision fees. Separate from the device charge, many jurisdictions bill for the probation or parole officer overseeing your case. Monthly amounts commonly run $25 to $65.2Interstate Commission for Adult Offender Supervision. Fees
- Administrative or application fees. Some agencies charge a one-time entry fee on top of installation, from $50 to several hundred dollars.
Stack the daily monitoring fee, supervision fee, testing, and any mandatory programs, and monthly out-of-pocket costs of $400 to $800 are realistic for many participants. Longer sentences or combined GPS-and-SCRAM assignments push that number higher.
What Makes One Person’s Bill Bigger Than Another’s
The gap between someone paying a few hundred dollars and someone paying several thousand comes down to three variables.
How Long You’re On the Program
Duration is the single biggest driver. Every additional day is another daily fee, and testing, supervision, and counseling also recur weekly or monthly. A 30-day stint might total $500 to $1,000. A year at the same daily rate can exceed $5,000.
Where You Live
Costs vary sharply from one county to the next. At least 26 states authorize electronic monitoring fees without setting a dollar amount, which effectively lets the monitoring provider, whether a government agency or private company, set the rate with minimal oversight. Private for-profit companies sometimes charge more than government-run programs because their pricing has to cover profit and overhead as well as equipment. Two people on identical sentences in neighboring counties can pay very different amounts.
Pretrial or Post-Conviction
Whether you’re being monitored before your case is resolved or after sentencing can affect what you owe. Twenty-nine states authorize fees during both phases, 13 authorize them only after sentencing, and one prohibits charging people who haven’t been convicted. If you’re on pretrial release, ask whether your jurisdiction charges the same rates as post-conviction participants.
Federal Home Detention Is Different
The federal system handles costs differently from most state and local programs. On federal pretrial release with location monitoring, the cost is split: you pay a co-payment, and the federal judiciary covers the rest.3United States Courts. Costs and Payment of Expenses Incurred for Location Monitoring
After sentencing, people on federal probation or supervised release pay a co-payment only if the court specifically orders one; the judiciary picks up any remaining expenses.3United States Courts. Costs and Payment of Expenses Incurred for Location Monitoring If you’re transitioning from a federal prison to home confinement near the end of your sentence under Bureau of Prisons authority, you pay nothing at all; the BOP reimburses the probation system.4Office of the Law Revision Counsel. 18 US Code 3624 – Release of a Prisoner Most state and local programs work the opposite way, with participants bearing the full cost.
Paying the Bill
In most state and local programs, you cover the monitoring and program costs yourself. Payment plans are common, letting you spread fees across the sentence rather than paying upfront. Some agencies collect through automatic payroll deductions.
Employment matters more than people realize. Courts routinely allow participants to leave home for work during approved hours, and staying employed is often both a program condition and the practical way to keep current on fees.
Hardship relief exists in some places, but it isn’t uniform. Only four states have statutes explicitly requiring courts to consider your ability to pay electronic monitoring fees during both pretrial and post-conviction stages. Another 23 states have no statutory ability-to-pay requirement at all. In those states, whether you get a reduced rate or a waiver depends on the judge and the monitoring agency’s policies. If money is a real problem, raise it early and in writing.
What Happens If You Fall Behind
Missed payments can be treated as a violation of your release or supervision conditions. Monitoring providers report payment delinquencies to the court alongside curfew breaches and other violations, and the judge decides how to respond.
The worst outcome is revocation, meaning the court ends your home detention and sends you to jail. The U.S. Supreme Court set a constitutional limit on that practice in Bearden v. Georgia, holding that revoking probation solely because someone cannot afford to pay, when the person has made genuine efforts and the failure is not their fault, violates the Fourteenth Amendment. Courts must first consider whether alternative punishments would serve the state’s interests before imprisoning someone for nonpayment.5Justia US Supreme Court. Bearden v. Georgia, 461 US 660 (1983)
The distinction matters. Willful refusal to pay when you have the money is one thing. Genuine inability to pay is another. If you can show real efforts to find work and pay what you owe, a court cannot automatically convert home detention into jail time. If a judge finds you had the resources and chose not to pay, or didn’t bother looking for work, imprisonment becomes a legitimate enforcement option.5Justia US Supreme Court. Bearden v. Georgia, 461 US 660 (1983) The gap between the legal standard and what happens in real courtrooms isn’t always clean, so documenting your financial situation, your job search, and every payment you make is worth the trouble.
