Surety bond premiums vary from one surety to another, but can range from one-half of one percent to two percent of the contract amount, depending on the size, type, and duration of the project and the contractor. In many cases, performance bonds incorporate payment bonds and maintenance bonds. When bonds are specified in the contract documents, it is the contractor’s responsibility to obtain the bonds. The contractor generally includes the bond premium amount in the bid and the premium generally is payable upon execution of the bond. If the contract amount changes, the premium will be adjusted for the change in contract price. Payment and performance bonds typically are priced based on the value of the contract being bonded, not necessarily on the size of the bond. Commercial bonding has a greater range of pricing; high risk programs have a high premium and 10% collateral.
