As part of the Affordable Care Act, the Health Insurance Marketplace is scheduled to open October 1, 2013. You can use the Kaiser Family Foundation’s online Subsidy Calculator to get an estimate of what your premiums and savings might be on a Marketplace plan. Keep in mind that this is just an estimate, and your actual costs may be higher or lower. When open enrollment in the Health Insurance Marketplace starts October 1, you’ll be able to see exactly what you’ll pay for specific plans, including any savings you qualify for based on your income.
