Every Texas surety bond has three numbers you should know: the face amount (set by the Texas obligee), the rate (set by the surety based on your credit and bond type), and the term (set by statute). Multiply the first two and apply the third, and you have the premium.
Face amount is non-negotiable. The Texas Legislature, TxDMV, the Comptroller, or the licensing agency fixes it. You cannot buy a smaller $25,000 dealer bond to save money - TxDMV will reject the filing. H.B. 3533 moved the dealer bond from $25,000 to $50,000 effective 2021, and the $25,000 figure still floating around online is wrong.
Rate is what we actually compete on. A surety pulls credit (except on filed-rate bonds like the notary), classifies you, and quotes a percentage of the face. Standard market starts around 1% for top credit; specialty markets go up to 10% for high-risk profiles. The surety files these rates with TDI under Texas Insurance Code Ch. 2253, so the same applicant should get a very similar rate from any honest Texas agency.
Term matters because TxDMV is 2 years, notary is 4 years, and most license bonds are 1 year. A $750 annual rate on a 2-year TxDMV bond shows up as a $1,500 binder, not $750 - the calculator pages bake this in so you do not get surprised at closing.
