Small business health insurance rates are defined by the kind of premiums and deductibles that you choose. A health insurance premium is a regular payment, the amount of which determines the maximum amount of your costs that are covered in the event of an illness. A deductible, on the other hand, is the amount of money you are required to pay for treatment before your health insurance plan can kick in. The choice of an optimal health plan would depend on your current health status and your average annual income.
