How to Cancel ADT Security in 2026 (Break the Contract + Avoid the 75% ETF)

Updated 2026-02-21 · 8 min read

⚠️ The contract trap: ADT locks you into 36-60 month contracts with an early termination fee (ETF) of 75% of your remaining monthly payments. On a $45/month plan with 24 months left, that's $810 to cancel. ADT is one of the hardest home services to leave in America.

What ADT Costs

Step 1: Check Your Contract Status

  1. Call ADT at 1-800-238-2727
  2. Ask: "When does my contract expire?" and "What is my early termination fee?"
  3. Get the answers in writing (email confirmation)
  4. Check if you're month-to-month — if your contract already expired, you can cancel with 30 days' notice and no ETF

Step 2: Cancel ADT

  1. Call 1-800-238-2727 (the only way to cancel — no online option)
  2. Say: "I want to cancel my ADT service"
  3. The retention team will offer discounts (often 30-50% off for 6-12 months) — decline if you're committed
  4. If under contract: they'll quote your early termination fee (75% of remaining payments)
  5. Request a cancellation confirmation in writing
  6. Return any ADT-owned equipment to avoid additional charges

How to Reduce or Avoid the ETF

💡 ETF math example: $45/mo × 18 months remaining × 75% = $607.50 ETF. Vs continuing payments: $45 × 18 = $810. If the ETF is close to remaining payments, it might be worth paying to escape — especially if you switch to a $0/month DIY system.
