Deductible
Deductibles are typically used to deter the large number of claims that a consumer can be reasonably expected to bear the cost of. By restricting its coverage to events that are significant enough to incur large costs, the insurance firm expects to pay out slightly smaller amounts much less frequently, incurring much higher savings. As a result, insurance premiums are typically cheaper when they involve higher deductibles. For example, health insurance companies offer plans with high premiums and low deductibles, or plans with low premiums and high deductibles. One plan may have a premium of $1,087 a month with a $6,000 deductible, while a competitive plan may have a premium of $877 a month with a $12,700 deductible. The consumer with the $6,000 deductible will have to pay $6,000 in health care costs before the insurance plan pays anything. The consumer with the $12,700 deductible will have to pay $12,700.
Progressivity in United States income tax
A taxpayer with $40,000 of wage income may only have the "standard" deductions available to him, whereas a taxpayer with $200,000 of wage income might easily have $50,000 or more of "itemized" deductions. Allowable itemized deductions include payments to doctors, premiums for medical insurance, prescription drugs and insulin expenses, state taxes paid, property taxes, and charitable contributions. In those two scenarios, assuming no other income, the tax calculations would be as follows for a single taxpayer with no dependents in 2006:
