Quick Answer: A typical homeowner should expect to pay between $20 and $100+ per month for a home security system. The two primary drivers of this recurring cost are professional alarm monitoring fees—which typically range from $20 to $60—and monthly installments for financed equipment, which can add another $10 to $70 to your bill.
What Determines Your Monthly Home Security Bill?
Your monthly Home Security bill is rarely a single flat fee. Instead, it is a combination of service costs and hardware debt. For a full breakdown of how to choose between these options, see our [Buying Guide].
Monthly Bill Components
Component | Typical Monthly Range |
Alarm Monitoring | $20 – $60 |
Financed Equipment | $10 – $70 |
Deep Dive: What Does Your Monthly Fee Cover?
The monthly subscription is more than just a fee for “turning the system on.” It covers the infrastructure required for 24/7 protection and advanced digital features.
- Professional Monitoring: This is the core service where a central station monitors your home 24/7. If a sensor is tripped, human operators verify the alarm and dispatch the police, fire department, or medical services.
- Connectivity: This is the delivery mechanism for your monitoring.
- Landline: Costs 10–30/mo. While cheaper, it is vulnerable; a single cut to your outdoor phone line can disable the system.
- Cellular (GSM): Costs 40–60/mo. Note that this higher price typically includes the professional monitoring service itself, providing a more secure, tamper-proof connection that cannot be physically cut.
- Features & App Access: For DIY-heavy plans, you may pay 4–20/mo specifically for cloud video storage, smart notifications (like person vs. package detection), and the ability to arm/disarm the system via a smartphone app.
- Environmental Protection: Don’t overlook non-burglary threats. Adding monitoring for life-safety devices increases the monthly cost.
- Smoke Detection: Approximately $2/mo.
- Flood and Carbon Monoxide (CO): Typically $7+/mo.

Home Security Cost: DIY vs. Professional Monitoring
The biggest decision affecting your budget is whether you choose to monitor the system yourself or hire professionals. While self-monitoring is tempting for the $0 price tag, it comes with significant risks.
Comparison Table
Feature | DIY Self-Monitored | Professionally Monitored |
Monthly Cost | $0 – $20/mo | $20 – $100+/mo |
Emergency Dispatch | None (User must call 911) | Automatic 24/7 Dispatch |
Travel Protection | Low (Vulnerable if away from phone) | High (Professionals respond 24/7) |
Smart Notifications | Included in paid tiers | Standard |
The Bottom Line on DIY: Self-monitoring requires you to be “on call” at all times. If you are on a plane, in a meeting, or sleeping, a security breach could go completely unnoticed until it’s too late. Professional monitoring provides the only true “safety net.”
Hidden and Upfront Costs to Expect
Don’t overlook the “sunk” costs that occur before your first monthly bill even arrives.
- Equipment Starter Kits: A basic kit averages 200**. Specific entry points include **Abode (130), SimpliSafe (250.96)**, and **ADT (269).
- Installation:
- DIY: Free.
- Professional: Starts at $99. Note that “white-glove” providers like ADT or Vivint often include this, but only if you sign a multi-year contract.
- Activation & Trials: Some providers charge a one-time activation fee. On the plus side, many kits now include a 30-day free trial of professional monitoring, allowing you to test the service before the monthly bills kick in.
- Contract Penalties: Be wary of long-term commitments. If you cancel a 3- or 5-year contract early, you may be hit with heavy cancellation fees.
Factors That Influence Your Final Price
Several variables can push a bill from the $20 baseline toward the $100+ ceiling:
- Home Size: More access points mean more sensors and cameras, increasing the total equipment cost and subsequent financing payments.
- Video Surveillance: High-volume video recording requires more cloud storage, which often forces you into a higher-priced monthly service tier.
- Smart Home Integrations: Integrating thermostats, door locks, and lighting adds to the upfront hardware cost and can increase monthly monitoring complexity.
- Financing Terms: Buying equipment upfront keeps your monthly bill low. Financing that same hardware over 24–60 months can add up to $70 to your monthly overhead.

Vivint vs ADT: Which Home Security Giant is Right for Your Home
Is Professional Home Security Worth the Cost?
When evaluating the monthly fee, you must look at the “Value Math” and potential return on investment.
Pro-Tip: The Insurance Discount Most insurers offer a 5% to 20% discount on premiums for homes with monitored security. For example, SimpliSafe provides a specific monitoring certificate you can email to your agent to trigger these savings. This discount often offsets a large portion of the monthly fee.
- The Burglary Math: The FBI estimates the average loss from a burglary at $2,416. If you pay $40/month for professional monitoring, your system only needs to prevent one burglary every five years to effectively pay for itself.
- Utility Savings: By pairing smart thermostats with your security system, you can reduce monthly heating and cooling bills, further lowering your total household expenses.
How to Lower Your Monthly Home Security Bill
- Buy Equipment Upfront: Eliminate the 10–70 monthly financing charge by paying for your hardware at checkout.
- Opt for DIY Installation: Avoid the $99+ professional labor fee by using the provider’s mobile app for self-setup.
- Bundle Equipment: Purchase pre-configured kits. A Ring 5-piece bundle costs $199.99, saving you $45 compared to buying the components individually.
- Leverage the 30-Day Trial: Use the free trial period included with most kits to determine if you actually need “Pro” features before you start paying.
Final Verdict
Home security costs are highly scalable. If you are budget-conscious, you can maintain a system for as little as 20 per month** by purchasing equipment upfront and choosing DIY installation. For those prioritizing 24/7 peace of mind and “white-glove” service, costs will likely lean toward the **100 range. Ultimately, the investment is often neutralized by insurance discounts and the significant cost-avoidance of a deterred burglary.
Home Security Monthly Cost FAQs
Is $20 a month enough for home security?
Yes, but with caveats. A $20 budget typically covers a basic professional monitoring plan or a premium DIY plan with video storage, provided you have already paid for your equipment in full upfront.
Is it cheaper to self-monitor a security system?
On paper, yes. Self-monitoring costs between $0 and $20. However, the “cost” of a missed alert while traveling can far exceed the monthly savings.
Do all home security systems have a monthly fee?
No. You can use many systems as “local alarms” (where only the siren sounds) for $0. However, you will lose remote app control, cloud video storage, and emergency dispatch.
Can you have home security without a monthly subscription?
Yes. This is called “unmonitored” or “self-monitored” security. You own the hardware, but you are the only one responsible for calling the police during an emergency.
How much does professional monitoring cost on average?
Professional monitoring averages $25 to $40 per month, though plans can range from $20 to over $100 depending on features and equipment financing.
