Did you sign with ADT within the last 3 business days?
The FTC Cooling-Off Rule covers certain household purchases made at home for $25 or more, but exclusions apply. For a covered sale, the cancellation deadline is midnight of the third business day after the sale. Saturdays count; Sundays and federal holidays do not. The seller must provide two cancellation forms and a dated contract or receipt. If forms are missing, write a cancellation letter; do not assume that missing paperwork gives you extra time.
Start with your signed service agreement and any separate equipment-financing agreement. ADT’s advertised professional-install offer specifies a 36-month service term, or 24 months in California, and a possible early termination charge of 75% of remaining monthly service charges. These terms do not establish every existing account’s obligations. The examples below assume a 36-month term, a $49.99 monthly service charge and that 75% formula; $49.99 is an illustration, not a current quote. Confirm your actual term, fees, remaining equipment balance and cancellation rights before choosing whether to stay or switch.
Your ADT options at a glance — full guidance below:
Three numbers every ADT decision depends on
Your current ETF (early termination fee)
If your agreement uses a 75% formula: (months remaining) × (monthly service charge) × 0.75. Illustration: 18 months at $49.99/mo = 18 × $49.99 × 0.75 = ~$675. Run the ETF Calculator → — it shows your cost to leave today, in 3 months, in 6 months, and at term end.
Your contract end date and the auto-renewal notice window
Find your actual end date, renewal period and cancellation instructions in your agreement. Confirm the notice deadline and effective cancellation date for your account; do not assume every agreement has a 30–60 day window or renews for another full initial term. The FTC and SCRA rights described here have their own requirements and can override ordinary contract procedures.
Your monthly rate and the price-change clause
Read the price-change clause in your signed agreement and the increase notice. Do not assume a universal 3–7% cap. ADT’s published residential service contract describes a written-objection deadline and conditional cancellation right when an increase is not waived. Check whether your own clause provides that option and act before its deadline.
The timeline below uses the illustrative 36-month, $49.99 service-charge and 75% ETF assumptions stated above. It excludes equipment financing and other charges. Substitute your actual agreement and balance; a legal cancellation right may change the result.
I signed with ADT within the last 1–3 business days (in-home sale)
Typical ETF: Possibly $0
→ Check the FTC Cooling-Off Rule callout at the top of this page before doing anything else. For a covered sale, timely cancellation can provide a full refund. Check the rule’s exclusions and mailing deadline; signing at home alone does not establish eligibility.
I am in months 1–6 of my ADT contract
Illustrative ETF: ~$1,125–$1,312 with 30–35 monthly payments remaining
→ A large ETF can make switching expensive, but it does not decide the outcome by itself. Compare the total cost of staying and switching over the same remaining period. Use your actual ETF, remaining financing, new equipment and installation costs, overlapping service charges and recurring fees. You can also ask whether a lower-cost plan or optional add-on removal is available.
I have 12–18 months remaining on my ADT contract
Illustrative ETF: ~$450–$675 with 12–18 monthly payments remaining
→ Run the ETF Calculator with your actual numbers. Compare staying and switching over the same period using an itemized replacement quote and your actual remaining obligations. A fixed breakeven threshold does not account for every buyer’s equipment costs, financing or expected service use.
I have 6–12 months remaining
Illustrative ETF: ~$225–$450 with 6–12 monthly payments remaining
→ Recalculate both options as the remaining term shortens. Under the example’s 75% formula, each paid month reduces the remaining service-charge ETF by about $37.49. A smaller ETF does not by itself establish whether waiting costs less; compare both options over the same remaining period. Start planning your exit: find your contract end date, mark the notice deadline in your agreement, and research your replacement system now.
I have 2–5 months remaining
Illustrative ETF: ~$75–$187 with 2–5 monthly payments remaining
→ Compare the remaining cost of staying with the full cost of switching before deciding. A short remaining term does not automatically make waiting cheaper. The most important action: mark your notice deadline. Check your agreement’s notice method, deadline and renewal period, and keep proof of your cancellation request.
My ADT contract is ending soon or has already ended
After the initial term: verify any remaining charges
→ After the initial term, an early termination charge may no longer apply, but notice-period service charges, equipment financing and switching costs can still matter. Ask for a dated, itemized final balance. Read the ADT contract-end guide before doing anything — it covers your 4 options, the auto-renewal trap, and what to say to retention right now.
Lower the bill without canceling
Best when: ETF exceeds 4–6 months of current payments and the system is otherwise working
Ask ADT to review your rate, optional add-ons and available plan changes. If the first representative cannot help, ask to speak with the team authorized to review those options for your account. Confirm any agreed price, service and term changes in writing.
Use a rate increase or service failure as leverage
Best when: you received a rate-increase notice or have documented service failures
Two contract provisions give ADT buyers legitimate grounds to dispute or exit — but both require documentation and neither is automatic.
Calculate the switching math
Best when: you suspect switching is worth it but haven't confirmed with actual numbers
If your agreement uses a 75% ETF formula, the service-charge portion decreases as remaining payments fall. In the $49.99 illustration, that decrease is about $37.49 per paid month. Whether switching makes financial sense depends on three inputs:
Exit with minimum ETF cost
Best when: you've decided to leave and want the lowest-cost exit path
Several circumstances allow ADT cancellation with a reduced or waived ETF:
Check whether your account has a temporary-pause option
Ask ADT whether a temporary or seasonal pause is available for your account. Do not assume that billing stops or that professional dispatch continues during a pause. Ask which services would change, the total charges, and whether the contract end date or cancellation fee would change.
How to request it: Contact ADT and ask: "Is a temporary pause available for my account, and what would it change?" If an option is offered, get the dates, charges, monitoring status, restart process and effect on your remaining obligations in writing before accepting it.
A pause is separate from cancellation. Check its written conditions rather than assuming it reduces your remaining term, bill or ETF. Full ADT bill-lowering guide including all hold and plan options →
These situations are worth comparing carefully. Use your own agreement and replacement quote to test whether staying costs less over the same period:
ETF exceeds 6 months of current payments with 10+ months remaining
A large ETF can outweigh expected savings, but calculate both totals before deciding. Compare the remaining service and financing costs of staying with all cancellation, equipment, installation and service costs of switching over the same dates. Ask whether any lower-cost plan is available.
4–6 months remaining on your ADT contract
In the stated example, 4–6 remaining payments produce a service-charge ETF of about $150–$225. Compare that amount with your actual savings and a written replacement-equipment quote. Mark your account’s cancellation deadline and check any remaining financing or final service charges before deciding to wait or switch.
ADT's retention team reduces your rate to within $8–$10 of what switching would save
A smaller recurring-cost difference leaves less room to recover switching costs. Use the actual rate offered in writing and compare both totals over the period you expect to use the system; a small monthly gap alone does not determine the cheaper option.
You actively use ADT's professionally installed system and have integrated smart-home devices
ADT's professional installation, UL-certified monitoring, and compatible smart-home hardware have real value if you use them. Use a written quote for any replacement equipment and installation. Consider the effort of installing and learning another system alongside the same-period cost comparison. How much that disruption matters is a personal preference, not a fixed financial rule.
Dealer contracts vary from ADT's published defaults — your signed agreement is what governs
ADT professional installations are often done by independent dealers who set their own terms. The rate ADT advertises, the term length ADT lists as standard, and the ETF formula ADT describes on its website may not match your specific signed service agreement. Always verify your actual contract terms — especially your price-change clause and notice window — before assuming anything.
Stopping payment is not the same as canceling
If you stop paying ADT, the contract does not simply end. ADT will pursue the ETF as a debt, can add late fees, and may report the account to collections — creating a credit problem on top of the contract problem. Use the cancellation method that applies to your account or legal right, and keep proof of the request and effective date. A phone call alone should not replace the written FTC notice or written or electronic SCRA notice described above. Stopping payment is not a contract exit strategy; it makes the situation worse.
Ask for the team that can review your account options
Explain the change you want and ask whether the representative can review it. If they cannot, ask who can handle the request for your account. Keep the case number and any written offer. A transfer or discussion does not establish that a discount, pause or waiver has been approved.
Check the renewal period and cancellation deadline in your agreement
Renewal and notice terms depend on your agreement. ADT’s published residential service contract describes successive 30-day renewals and advance notice; do not assume a new multi-year term. Check the clause that applies to your account and ask for written confirmation of the end date and final bill. Ordinary renewal terms do not replace applicable FTC or SCRA cancellation rights.
Confirm equipment ownership, return requirements and compatibility
Before canceling, ask ADT to confirm which equipment you own, whether anything must be returned, and what will work on your exact system after service ends. Do not assume the local siren, app access, cameras or smart-home features will continue. If you plan to switch providers, have the replacement provider confirm compatibility and any replacement costs for your panel and sensors before including them in your savings estimate.
