Estimate ACA subsidies, Marketplace premiums, Medicaid eligibility & tax credits with our 2024 KFF Health Insurance Calculator.

KFF Health Insurance Marketplace Calculator (2024 Subsidy & Premium Estimator)

Understanding your health insurance costs under the Affordable Care Act (ACA) can be complicated. Premium tax credits, Medicaid eligibility, cost-sharing reductions, and plan comparisons all depend on income, age, household size, and state rules.

Our KFF Health Insurance Marketplace Calculator helps you quickly estimate:

  • Income as a percentage of the Federal Poverty Level (FPL)
  • Premium tax credit (monthly subsidy)
  • Bronze, Silver, and Gold plan premiums
  • Annual subsidy amount
  • Cost-Sharing Reduction (CSR) eligibility
  • Medicaid eligibility indicators
  • Employer coverage impact

Inspired by data modeling approaches from KFF (formerly Kaiser Family Foundation), this tool provides a fast, user-friendly way to preview your 2024 Marketplace costs before enrolling.

What Is the Health Insurance Marketplace?

The Health Insurance Marketplace allows individuals and families to buy coverage if they do not have affordable employer-sponsored insurance. Most states use HealthCare.gov, while some operate their own exchanges.

Under the ACA, financial assistance is available to reduce both:

  • Monthly premiums (Premium Tax Credits)
  • Out-of-pocket costs (Cost-Sharing Reductions for eligible Silver plan members)

This calculator helps you estimate both.

How the KFF Marketplace Calculator Works

The tool calculates subsidy eligibility and premium estimates using several factors:

1. State Selection

Premiums and Medicaid expansion rules vary by state. The calculator allows selection from states such as:

  • California
  • Texas
  • Florida
  • New York
  • Georgia
  • Washington
  • Illinois
  • Colorado
  • Alabama
  • Alaska
  • Arizona
  • Arkansas
  • Connecticut

Your state impacts eligibility thresholds and base premium estimates.

2. County (Optional)

Entering your county can help refine premium estimates, as insurance pricing differs by rating area.

3. Annual Income (Before Taxes)

Your total projected yearly income determines your percentage of the Federal Poverty Level (FPL). This percentage determines:

  • Whether you qualify for Medicaid
  • Whether you qualify for subsidies
  • How large your tax credit will be

4. Family Size & Adults Enrolling

Larger households have higher FPL thresholds. The calculator adjusts poverty percentages and premium estimates accordingly.

5. Oldest Adult Age

Premiums increase with age under ACA rules. The calculator applies age-rating factors, meaning older adults typically see higher base premiums.

6. Employer Coverage

If you are offered affordable employer-sponsored coverage, you generally cannot qualify for Marketplace subsidies. The tool checks this condition before calculating tax credits.

7. Tobacco Use

Insurance companies may charge higher premiums for tobacco users. The calculator increases premium estimates when tobacco use is selected.

How to Use the KFF Health Insurance Marketplace Calculator

Using the tool is simple:

  1. Select your state.
  2. (Optional) Enter your county.
  3. Input your annual income before taxes.
  4. Select the number of people enrolling.
  5. Choose the number of adults.
  6. Enter the oldest adult’s age.
  7. Indicate if employer coverage is offered.
  8. Select tobacco usage status.
  9. Click Calculate.

The results section will instantly display:

  • Income as % of Poverty Level
  • Subsidy eligibility status
  • Monthly premium tax credit
  • Estimated Bronze, Silver, and Gold premiums
  • Annual subsidy amount
  • CSR eligibility level
  • Medicaid eligibility indicator

You can reset the calculator anytime to test different income or plan scenarios.

Example Scenario

Let’s walk through a sample case:

  • State: Texas
  • Family Size: 4
  • Adults: 2
  • Oldest Adult Age: 47
  • Income: $65,000
  • Employer Coverage: No
  • Tobacco Use: No

Step 1: Poverty Level Percentage

The tool calculates income relative to the FPL for a 4-person household.

Step 2: Determine Eligibility

If income falls between 100%–400% of FPL, the household may qualify for premium tax credits.

If income is below 138% of FPL in expansion states, Medicaid eligibility may apply.

Step 3: Calculate Benchmark Premium

The Silver plan acts as the benchmark for calculating subsidies.

Step 4: Apply Contribution Cap

The ACA limits how much of your income you must pay toward premiums.

Step 5: Calculate Premium Tax Credit

If the benchmark premium exceeds your capped contribution, the difference becomes your monthly tax credit.

The calculator then adjusts Bronze, Silver, and Gold premiums accordingly.

Understanding Marketplace Plan Levels

Bronze Plans

  • Lowest monthly premiums
  • Highest deductibles
  • Good for healthy individuals with minimal care needs

Silver Plans (Benchmark)

  • Moderate premiums
  • Balanced cost-sharing
  • Required to qualify for Cost-Sharing Reductions

Gold Plans

  • Higher premiums
  • Lower deductibles
  • Ideal for frequent healthcare use

Medicaid Eligibility Explained

If your income falls below 138% of FPL in states that expanded Medicaid, you may qualify for Medicaid instead of Marketplace subsidies.

The calculator shows:

  • “May Qualify for Medicaid”
  • “Yes (if state expanded Medicaid)”

This helps you understand whether Marketplace coverage is your best option.

What Are Cost-Sharing Reductions (CSR)?

CSR benefits lower:

  • Deductibles
  • Copayments
  • Out-of-pocket maximums

To qualify:

  • Income must generally be between 100%–250% of FPL
  • You must enroll in a Silver plan

The calculator displays CSR levels such as:

  • Highest Level
  • High Level
  • Moderate Level

Why Use This Marketplace Calculator?

✔ Fast subsidy estimates
✔ Compare Bronze, Silver & Gold plans
✔ Identify Medicaid eligibility
✔ Check employer coverage impact
✔ Estimate annual subsidy savings
✔ Plan your healthcare budget

Important Disclaimer

  • Estimates are based on 2024 Marketplace modeling.
  • Actual premiums vary by insurer and county.
  • Medicaid eligibility depends on state expansion status.
  • Always confirm final eligibility at HealthCare.gov or your state Marketplace.

15 Frequently Asked Questions (FAQs)

1. What is the Federal Poverty Level (FPL)?

A federal income guideline used to determine eligibility for subsidies and Medicaid.

2. How is the premium tax credit calculated?

It’s the difference between the benchmark Silver premium and your capped income contribution.

3. Why is the Silver plan used as a benchmark?

The ACA uses the second-lowest-cost Silver plan to determine subsidies.

4. Does employer coverage affect eligibility?

Yes. If affordable employer coverage is offered, you typically cannot receive Marketplace subsidies.

5. What happens if my income is below 138% of FPL?

You may qualify for Medicaid in expansion states.

6. Do tobacco users pay more?

Yes. Tobacco use may increase premiums.

7. Can I get subsidies above 400% of FPL?

Enhanced ACA rules may still limit your premium contribution.

8. What is CSR?

Cost-Sharing Reduction lowers deductibles and copays for eligible Silver plan members.

9. Does age increase premiums?

Yes. ACA rules allow higher premiums for older adults.

10. Is this calculator official?

No. It provides estimates for planning purposes only.

11. Can I compare multiple income scenarios?

Yes. Simply reset and enter new values.

12. Are Gold plans eligible for CSR?

No. CSR benefits apply only to Silver plans.

13. Are subsidies paid monthly?

Yes. Premium tax credits reduce your monthly premium.

14. What if my income changes mid-year?

You should report changes to avoid tax reconciliation issues.

15. Is this tool free to use?

Yes. It’s completely free with no registration required.

Km Per Hour Calculator – Calculate Speed, Distance, Time & Pace Instantly

Need to calculate speed in kilometers per hour? Want to convert km/h to mph or meters per second? Our Km Per Hour Calculator is a powerful and easy-to-use online tool that helps you calculate:

  • Speed (km/h)
  • Distance (km & miles)
  • Time (hours, minutes, seconds)
  • Speed in mph
  • Speed in m/s
  • Pace per kilometer

Whether you're a runner, cyclist, driver, student, or athlete, this calculator makes motion calculations fast and accurate.

What Is Km Per Hour (km/h)?

Kilometers per hour (km/h) is a unit of speed that measures how many kilometers are traveled in one hour. It is widely used in most countries for:

  • Road speed limits
  • Vehicle speedometers
  • Running and cycling tracking
  • Transportation planning

If you live in countries using miles per hour (mph), this tool also converts km/h into mph automatically.

What Can This Km/h Calculator Do?

Unlike basic calculators that only compute speed, this tool supports three calculation modes:

  1. Calculate Speed (km/h) – When distance and time are known
  2. Calculate Distance (km) – When speed and time are known
  3. Calculate Time – When distance and speed are known

It also provides automatic unit conversions and running pace calculations.

Speed Formula Explained

The calculator uses the standard motion formula:

Speed = Distance ÷ Time

From this formula, we can also calculate:

  • Distance = Speed × Time
  • Time = Distance ÷ Speed

The tool handles all the unit conversions behind the scenes.

You can click Reset anytime to start over.

Example Calculations

Example 1: Calculate Speed

Distance: 10 km
Time: 50 minutes

Convert 50 minutes into hours:

50 ÷ 60 = 0.83 hours

Speed = 10 ÷ 0.83 = 12 km/h

The calculator will also show:

  • 7.46 mph
  • 3.33 m/s
  • Pace: 5:00 min/km

Example 2: Calculate Distance

Speed: 80 km/h
Time: 2 hours

Distance = 80 × 2 = 160 km

In miles:
160 × 0.621371 = 99.42 miles

Example 3: Calculate Time

Distance: 5 km
Speed: 10 km/h

Time = 5 ÷ 10 = 0.5 hours

0.5 hours = 30 minutes

Km/h to mph Conversion

To convert km/h to mph:

mph = km/h × 0.621371

Example:
100 km/h = 62.14 mph

The calculator performs this conversion automatically.

Km/h to m/s Conversion

To convert km/h to meters per second:

m/s = km/h ÷ 3.6

Example:
36 km/h = 10 m/s

This is useful for physics problems and scientific calculations.

Understanding Pace (Minutes per Kilometer)

Pace is commonly used in running and cycling. It shows how many minutes it takes to travel one kilometer.

Formula:

Pace = 60 ÷ Speed (km/h)

Example:
Speed = 12 km/h

60 ÷ 12 = 5

Pace = 5:00 min/km

The calculator automatically formats pace into minutes and seconds.
