Customers typically pay this range, from the sources below, so you can sanity check your total.
Sample prices, not a quote. Customers typically pay $450 to $950 to install an interlock kit, and the device itself is often $50 to $150. A manual transfer switch is a heavier job: one guide puts that switch install at $1,200 to $1,600. The $750 sample is the inlet and the interlock, so it sits inside the interlock band and below the switch price on purpose. The kit on this estimate is $85, inside the $50 to $150 device figure.
Interlock kits run between $450 and $950 to install, with most people spending $50 to $150 on the device itself and the rest on labor.

Frequently asked questions.
How do electricians price a generator interlock?
Price the listed kit, the inlet, the breaker, the short conduit run, the permit, and the hours in the panel. Installed interlock kits run about $450 to $950, with the device often $50 to $150. This sample is $750.
What should an inlet and interlock estimate include?
The kit model, the inlet amperage, the conduit length, and a clear note that a transfer switch is not included. This sample is the interlock path, not the switch.
How long does an interlock install take?
The sample uses 4 hours for the panel, the inlet, and the interlock, plus a short return for inspection. A meter pull or a panel that will not take the kit takes longer.
Should a transfer switch be the same estimate?
No. A manual transfer switch is commonly priced around $1,200 to $1,600 installed, above this interlock. Write it as its own estimate if that is what the customer wants.
Are these prices a real quote?
No. The lines are sample prices so you can see the shape of the estimate. In the app, the estimate follows the job you describe, your answer, and your prices.
