How much does the California contractor bond cost?

The required bond amount is $25,000, but you do not pay that. You pay an annual premium to a surety, priced off your credit and the bond amount.

What other costs are there beyond the license fee?

Beyond the state fee you should budget for the exam, general liability insurance, forming your business entity, and the truck and tools you need to take the first job. Those are billed by separate providers, not the licensing board.
