The benchmark second-lowest-cost Silver plan in Miami-Dade for a 40-year-old is approximately $463 per month before Premium Tax Credits are applied. This benchmark figure is what the ACA uses to calculate your subsidy — your actual net premium depends on your income relative to the Federal Poverty Level.
| Annual Income (single adult) | % of 2026 FPL | Est. net monthly premium | Notes |
|---|---|---|---|
| ~$16,000 - $24,000 | 100-150% | $0 - $50 | Likely $0 on benchmark Silver; Enhanced Silver CSRs apply |
| ~$24,000 - $32,000 | 150-200% | $50 - $120 | Strong subsidy; Enhanced Silver CSRs apply |
| ~$32,000 - $48,000 | 200-300% | $120 - $280 | Meaningful subsidy |
| ~$48,000 - $64,000 | 300-400% | $280 - $450 | Moderate subsidy |
| Above $64,000 | 400%+ | Varies | May still qualify if benchmark premium >8.5% of income |
Use the calculator above for a precise estimate based on your actual household size and income. Note that the figures above reflect single-adult estimates — premiums for families scale with household size but subsidies scale as well.
Miami-Dade residents earning at or above 100% of the 2026 Federal Poverty Level (approximately $15,960 for a single person) may qualify for Premium Tax Credits. Florida has not expanded Medicaid, which means adults earning below 100% FPL without children or a disability generally do not qualify for Medicaid and cannot receive marketplace subsidies — this is the Florida coverage gap. If you earn below this threshold, you can still purchase an unsubsidized marketplace plan, though the cost without assistance can be significant.
For residents who do qualify for subsidies, the credit is applied monthly to reduce your premium before you pay it. You can apply through HealthCare.gov, which will calculate your subsidy automatically based on the income you enter.
