ACA Affordability Calculator 2025
Use this tool to estimate if employer-sponsored health coverage meets the Affordable Care Act's (ACA) affordability standard for 2025.
Understanding ACA Affordability for 2025
The Affordable Care Act (ACA), often known as Obamacare, includes provisions designed to ensure that health coverage offered by employers is genuinely affordable for their employees. This is particularly crucial for Applicable Large Employers (ALEs) – those with 50 or more full-time equivalent employees – who are subject to the Employer Mandate.
What is the ACA Affordability Rule?
Under the ACA, an employer-sponsored health plan is considered "affordable" if the employee's required contribution for the lowest-cost self-only coverage does not exceed a certain percentage of their household income. If an employer offers coverage that is not affordable, and at least one full-time employee receives a premium tax credit for purchasing coverage through a Health Insurance Marketplace, the employer may be subject to penalties.
The 2025 Affordability Threshold
The affordability threshold is adjusted annually by the IRS. For 2024, this percentage was 8.39%. While the final percentage for 2025 is typically released in late summer or early fall of the preceding year, it is widely anticipated to remain around this figure or be adjusted slightly based on premium growth rates. For the purpose of this calculator and current planning, we are using an estimated 8.39% for 2025.
- If the employee's contribution for self-only coverage is equal to or less than 8.39% of their household income, the coverage is considered affordable.
- If it is greater than 8.39%, the coverage is deemed unaffordable.
How to Use the ACA Affordability Calculator
Our 2025 ACA Affordability Calculator simplifies this complex calculation. To get an accurate estimate, you'll need two key pieces of information:
- Annual Household Income: This is your Modified Adjusted Gross Income (MAGI) for your tax household. It includes income from all sources for all members of your tax household.
- Monthly Cost of Lowest-Cost Self-Only Plan: This refers to the portion of the premium that the employee is required to pay each month for the cheapest health plan offered by their employer that provides "minimum value" (covers at least 60% of total average costs for a standard population). Crucially, this is for self-only coverage, not family coverage.
Simply enter these values into the fields above, click "Calculate Affordability," and the tool will tell you whether the plan meets the 2025 affordability standard.
Who Needs to Pay Attention to Affordability?
Employers and the Mandate
ALEs must offer affordable, minimum essential coverage that provides minimum value to their full-time employees and their dependents. Failure to meet the affordability standard can trigger IRS penalties (the "B" penalty) if an employee obtains a premium tax credit on the Marketplace.
Employees and Premium Tax Credits
For employees, the affordability rule is critical because it determines eligibility for premium tax credits (subsidies) on the Health Insurance Marketplace. If an employer offers affordable coverage, the employee is generally not eligible for Marketplace subsidies, even if they choose not to enroll in the employer's plan. If the employer's plan is unaffordable, or doesn't provide minimum value, the employee may be eligible for subsidies if their income falls within a certain range.
Important Considerations and Nuances
Self-Only Coverage vs. Family Coverage
A common misconception is that the affordability rule applies to family coverage. However, the IRS affordability test is based solely on the employee's cost for self-only coverage. An employer can offer affordable self-only coverage but very expensive family coverage, and still meet the ACA's affordability requirements. This is often referred to as the "family glitch" for employees, as it can prevent families from accessing Marketplace subsidies.
Affordability Safe Harbors
Employers can use one of three IRS-established "safe harbors" to determine affordability without having to know each employee's actual household income:
- W-2 Wage Safe Harbor: The employee's share of the premium doesn't exceed the affordability percentage of the employee's W-2 wages.
- Rate of Pay Safe Harbor: The employee's share of the premium doesn't exceed the affordability percentage of their hourly or monthly rate of pay.
- Federal Poverty Line (FPL) Safe Harbor: The employee's share of the premium doesn't exceed the affordability percentage of the federal poverty line for a single individual.
These safe harbors provide employers with flexibility and a simplified way to comply with the mandate.

Conclusion
Staying informed about ACA affordability standards is essential for both employers and employees. For 2025, the estimated 8.39% threshold will continue to be a key benchmark. Use this calculator as a helpful tool to gauge affordability, but always verify with official IRS publications and seek professional guidance when making critical health coverage decisions.
