ADT contracts typically run 36 months at $28-$60/month — that's up to $2,160 over the contract. Cancel early and you'll face an early termination fee (ETF) of 75% of your remaining balance. But there are ways around it.
ADT requires a 36-month contract for most plans. Cancel 12 months in with a $45/month plan, and your ETF is: 24 months × $45 × 75% = $810. That's not a cancellation fee — it's a hostage payment.
If your 36-month contract has expired, you're month-to-month and can cancel with no ETF:
ADT requires written notice. Send your cancellation letter via USPS Certified Mail with Return Receipt ($4.85). This gives you legal proof they received it — ADT has been known to claim they "never received" cancellation requests.
If you're moving to a location where ADT doesn't offer service, you may be able to cancel without an ETF. This includes:
ADT allows you to transfer your contract to a new homeowner if you're selling your house. This is the cleanest exit:
If you signed up within the last 3 business days, you can cancel penalty-free under the FTC's Cooling-Off Rule. Send written notice immediately.
If ADT has failed to provide adequate service (false alarms not addressed, equipment failures, slow response times), document everything and use it as grounds for contract termination without ETF. File complaints with:
