ADT pricing: DIY plans, professional offers and contract costs

Start by choosing the installation and response you need. ADT Blu DIY subscriptions and professionally installed service have different equipment, prices and agreements. This guide compares named options rather than treating one advertised starting price as the cost of every ADT system.

Checked September 9, 2026. U.S. manufacturer prices and terms linked below. This is a dated source review, not a hands-on test or a guarantee of future prices. Equipment, monitoring, cancellation and total-cost calculations are covered separately.

Our method and commercial disclosure: See our methodology → See full disclosure →

Equipment and setup

For professional installation, the current advertised offer is a $99 system with specified installation: one ADT Base, three door/window sensors, one motion sensor and a choice of eligible Google Nest camera. It requires a qualifying service agreement, AutoPay, a phone order and new-customer credit approval; availability and added equipment affect the quote. The offer expires November 9, 2026. Read the exact offer terms →

For Blu DIY, obtain a cart listing every sensor, camera and compatible subscription. Do not transfer a promotional kit price to a different equipment configuration. Installation is your responsibility; verify existing-device compatibility before assuming you can reuse hardware.

Return terms: ADT’s six-month money-back provision concerns an unresolved installation or system issue after ADT attempts to fix it. It requires continuous professional monitoring and QSP coverage from activation, equipment return and other conditions. It is not a general six-month trial. ADT guarantee conditions →

Plans and billing

The first three rows are the with-cameras options on the Blu DIY monitoring page. They require compatible hardware. The last row is the separate professional-install offer described above. “12 monthly payments” is arithmetic, not an annual billing discount.

Plan / offer Monthly service 12 monthly payments Response and scope
Blu Video Connect $9.99 $119.88 Camera live view and recorded clips; no professional alarm monitoring.
Blu Self-Protect with cameras $14.99 $179.88 User monitors the system; remote arm/disarm and camera features. No professional dispatch.
Blu Pro-Protect with video $34.99 $419.88 Professional alarm monitoring plus video features.
Specified professional-install offer From $59.99 From $719.88 Separate service agreement; equipment/setup amount and term shown above.

Sources: Blu monitoring plans and professional offer terms. Other configurations and add-ons can cost more. Check the order summary for taxes, permits, local response fees and any required services.

Contract terms and cancellation

The cited professional offer requires 36 months of monitoring, or 24 months in California. ADT may charge 75% of the service charges left in the initial term for early termination. Blu advertises no long-term monitoring contract; promotional purchases can still require an initial month and a compatible plan. Your signed order controls.

Illustrative cancellation calculation: after 12 of 36 months at $59.99/month, 24 × $59.99 × 0.75 = $1,079.82. This estimates the service cancellation fee only. It excludes any separately owed equipment, taxes or other charges. Use your own remaining months and contracted rate.

Three-year cost calculations

The professional offer’s minimum three-year arithmetic is $99 + ($59.99 × 36) = $2,258.64, before taxes, extra equipment and applicable fees. For California’s 24-month initial term, the corresponding calculation is $99 + ($59.99 × 24) = $1,538.76; service after that term would add cost.

Blu DIY subscription 36 monthly payments, service only
Video Connect $359.64
Self-Protect with cameras $539.64
Pro-Protect with video $1,259.64

To turn a service total into a system total, add your equipment purchase, installation if applicable, selected add-ons and taxes. These calculations assume unchanged rates and no trial credit; they are not a locked three-year offer for month-to-month service.

  • Ask for an itemized installation and equipment quote, including extra devices or wiring.
  • Confirm permits, local response charges, financing costs and cancellation obligations.
  • Identify which alarm, video and smart-home functions your exact hardware and plan support.

Who should consider ADT?

Consider professional installation if you want an installer to configure the system and accept the quoted service commitment. Compare Blu DIY if you prefer installing compatible equipment yourself and choosing between self-monitoring and professional response.

If you expect to move or cancel soon, calculate the exit cost before signing. An insurer decides whether your policy qualifies for a discount; brand recognition alone does not establish eligibility.

ADT pricing questions

Does the lowest ADT Blu price include professional alarm monitoring?

No. Video Connect is a camera subscription. In the with-cameras options listed here, Pro-Protect with video is the professional alarm-monitoring plan. Match the plan to compatible equipment and your desired response.

Is $99 the complete cost of the ADT professional offer?

No. It is the advertised system and specified installation amount for a qualifying offer. Monitoring, taxes, extra equipment and applicable fees add to the total. Review the offer conditions and written quote before ordering.

How is an ADT early termination fee calculated?

For the cited offer, multiply remaining service months by the contracted monthly service rate and 75%. For example, 24 months at $59.99 gives $1,079.82. Confirm the formula and any other obligations in your own agreement.

Are the three-year totals guaranteed prices?

No. They are calculations using the listed inputs, with no rate changes or trial credits assumed. Month-to-month service can change, and hardware, add-ons and local charges can change the full cost.
