ACA Premium Subsidy Calculator 2026: Marketplace Tax Credit Estimator
The Affordable Care Act (ACA) premium tax credit helps eligible households pay for health insurance purchased through the marketplace (HealthCare.gov or your state exchange). For2026, the enhanced subsidies from the American Rescue Plan Act (ARPA) and Inflation Reduction Act (IRA) have expired. The original ACA applicable percentage schedule and the 400% FPL subsidy cliff have returned. Use the calculator below to estimate your expected premium contribution.
ARPA/IRA enhancements expired in 2026
From 2021 through 2025, the ARPA and IRA temporarily made ACA subsidies more generous. Those enhancements included: eliminating the 400% FPL income cliff (so even higher-income households could qualify), capping everyone's premium contribution at 8.5% of income, and lowering the applicable percentages across all income levels. All of these enhancements expired on December 31, 2025.
Starting in 2026, the ACA reverts to its original subsidy structure under IRC §36B. The key changes compared to 2025:
- The 400% FPL cliff is back. If your household income exceeds 400% of the Federal Poverty Level, you get zero subsidy. For a family of 4, that threshold is approximately $128,600 (using 2025 FPL as reference , verify 2026 FPL when published).
- Higher applicable percentages. The percentage of income you're expected to pay toward premiums is higher than under ARPA/IRA, especially for middle-income households.
- No cap for above-cliff households. Under ARPA/IRA, even those above 400% FPL paid no more than 8.5% of income. That cap no longer applies.
How the Premium Tax Credit Works
The premium tax credit (PTC) is calculated as the difference between two numbers:
- Benchmark premium: The cost of the second-lowest-cost Silver plan (SLCSP) in your area for your household.
- Expected contribution: Your household income multiplied by the applicable percentage from the table below.
Subsidy = SLCSP Premium − Expected Contribution. If the SLCSP costs $800/month and your expected contribution is $300/month, your subsidy is $500/month. You can apply this subsidy to any metal-level plan. This calculator estimates your expected contribution only , you need your local SLCSP premium (from HealthCare.gov) to determine the actual subsidy amount.
2026 Applicable Percentage Table (Pre-ARPA Schedule)
The applicable percentage determines what share of income a household is expected to pay toward the SLCSP premium. Income is measured as a percentage of the Federal Poverty Level (FPL). The percentage interpolates linearly between the initial and final values within each bracket.
Percentages are from Rev. Proc. 2025-25 section 3.01, Table 1 (inflation-adjusted for 2026). Post-ARPA rates apply; enhanced ARPA/IRA subsidies expired after 2025.
| Income as % of FPL | Initial Premium % | Final Premium % |
|---|---|---|
| 100% – 133% | 2.10% | 2.10% |
| 133% – 150% | 3.14% | 4.19% |
| 150% – 200% | 4.19% | 6.60% |
| 200% – 250% | 6.60% | 8.44% |
| 250% – 300% | 8.44% | 9.96% |
| 300% – 400% | 9.96% | 9.96% |
| Above 400% | No subsidy (the cliff) | |
Worked Examples
Note: These examples use 2025 FPL values, which are the correct guidelines for 2026 marketplace coverage per the prior-year rule (26 U.S.C. 36B(d)(3)(A)).
Example 1: Family of 4, $60,000 Income, Eligible
Profile: Family of 4, $60,000 MAGI, contiguous 48 states
Income as % of FPL = $60,000 ÷ $32,150 = 186.6%
Falls in 150%–200% bracket (initial 4.00%, final 6.50%)
Applicable percentage = 5.83%
Expected annual contribution = $60,000 × 5.83% = $3,499
Monthly contribution = $292
Subsidy = your SLCSP premium − $292/month
Example 2: Family of 4, $140,000 Income, Hits the Cliff
Profile: Family of 4, $140,000 MAGI, contiguous 48 states
Income as % of FPL = $140,000 ÷ $32,150 = 435.5%
435.5% > 400% FPL cliff
Subsidy = $0. Above the cliff, not eligible for premium tax credits.
Under ARPA/IRA (2021–2025), this family would have paid at most 8.5% of income ($11,900/year). In 2026, they pay full premium with no assistance.
Example 3: Single Person, $35,000 Income, Eligible
Profile: Single, age 40, $35,000 MAGI, contiguous 48 states
Income as % of FPL = $35,000 ÷ $15,650 = 223.6%
Falls in 200%–250% bracket (initial 6.50%, final 8.10%)
Applicable percentage = 7.26%
Expected annual contribution = $35,000 × 7.26% = $2,540
Monthly contribution = $212
Subsidy = your SLCSP premium − $212/month
