ADT charges an early termination fee (ETF) equal to 75% of your total remaining monthly contract charges if you cancel before your initial 24-month (California) or 36-month (most other states) commitment ends. Once your initial agreement is fulfilled, the service rolls over to a month-to-month basis with no cancellation fee.

If you're canceling ADT because of high monthly fees or long contracts, you're not alone. Many people switch to home security systems with no contracts, lower monthly costs, and easier setup. Fortunately, it's easy to find top-rated home security systems that don't require long-term commitments.
When you cancel your ADT service, your physical alarm panel will continue to function as a local siren and noisemaker, but it will no longer contact ADT or the police.
ADT does not offer a standalone "senior discount," but seniors aged 50+ who are AARP members receive 5% off monthly professional monitoring services. To redeem this, you must call ADT directly (e.g., at 1-800-973-0958) and provide your AARP membership number.
Monthly professional monitoring starts at $24.99, while the top-tier plan starts at $39.99. If you opt for professional installation, you'll need to pay a $100 fee and expect a three-year contract. ADT isn't the most budget-friendly security system out there, but it's a genuinely competitive one.
