The Health Insurance Marketplace Calculator, updated with 2019 premium data, provides estimates of health insurance premiums and subsidies for people purchasing insurance on their own in health insurance exchanges (or “Marketplaces”) created by the Affordable Care Act (ACA). With this calculator, you can enter your income, age, and family size to estimate your eligibility for subsidies and how much you could spend on health insurance.
Short-term health insurance plans are able to charge premiums 54 percent lower than ACA-compliant plans, by excluding pre-existing conditions and severely limiting benefits.
In health insurance systems designed to protect people with pre-existing conditions and guarantee availability of coverage regardless of health status, countervailing measures are also needed to ensure people do not wait until they are sick to sign up for coverage (as doing so would drive up average costs for other enrollees). The Affordable Care Act (ACA) included a variety of “carrots” (e.g., premium tax credits and cost-sharing reductions) and “sticks” (e.g., the individual mandate penalty…
This tracker monitors preliminary 2019 premiums in the Affordable Care Act’s marketplaces as insurers file rate information with state regulators. It shows preliminary premium information in a major city in each available state for the lowest-cost bronze plan and “benchmark” silver plan, which is used to determine the size of the premium tax credits available to low- and moderate-income enrollees. The tracker also shows how those premiums are changing from 2018 and what a 40-year-old…

The decline was concentrated in off-exchange plans where enrollees are not eligible for Affordable Care Act subsidies and have had to pay the full cost of recent premium increases. At the same time, enrollment in plans sold through the…

The Kaiser Family Foundation today launched a tracker to monitor preliminary 2019 premiums in the Affordable Care Act’s marketplaces as insurers file rate information with state regulators.

This brief examines recently-released annual financial data from 2017 and finds insurers selling individual market plans had their best financially since 2014, when new ACA insurance market rules took effect that guaranteed access to coverage for people with pre-existing conditions. At the same time, recent political and policy changes, including the repeal of the individual mandate penalty as part of tax reform legislation and proposed regulations to expand loosely-regulated short-term insurance plans, cloud plans’ outlook…
