These are the lowest figures each provider publishes, so the 6 and 12 month totals are a floor, not a quote. They add the install fee, the monthly lease, calibration visits and removal where published. An asterisk means a fee is not published and is not included. Per day rates are counted as 30 days a month.

How the estimate is built
An interlock program has four kinds of charges. The installation fee is paid once at the shop. The lease is a monthly charge for the device, and many providers quote it per day. Calibration is a service visit the state requires on a fixed schedule, usually every 30 or 60 days, and some providers roll it into the lease while others bill each visit. Removal is paid once at the end.
The 6 and 12 month figures add those together using the lowest number each provider publishes. Where a provider does not publish a fee, the estimate leaves it out and says so. Deposits, device protection plans, missed appointment charges and state program fees are not included.
What changes the price
- Your state may require a camera, GPS or real time reporting, which raises the lease.
- Program length is set by the court or licensing agency, not the provider.
- Some states run indigent or reduced fee programs. Ask the provider and your monitoring authority.
- Shops set their own installation and removal labor charges within the range the provider allows.
