| December 15, 2026 | Pick a plan by today for a January 1 start |

Rate Changes by Insurer
Ohio's individual market rates rise about 16.3% on average, after a 19.8% jump in 2026. Each company asked for a very different change, though.| Insurer | Requested average change |
|---|---|
| Oscar Insurance Corp. of Ohio | -1.5% |
| Ambetter from Buckeye Health Plan | +9.5% |
| Summa | +10.4% |
| Antidote Health | +15.8% |
| Anthem | +16.2% |
| Oscar Buckeye State | +18% |
| MedMutual | +21.6% |
| UnitedHealthcare | +24.1% |
Requested rates from RateReview.HealthCare.gov, per healthinsurance.org. AmeriHealth Caritas is new, so it has no prior rate. With swings this wide, the cheapest plan in your county may change. That is a strong reason to compare before you renew.
How Subsidies Work in Ohio Now
Ohio expanded Medicaid, so adults earning up to 138% of the poverty level usually qualify. Above that, Marketplace tax credits lower your premium. In 2026, about 8 in 10 Ohio enrollees got that help. The bigger federal subsidies ended after 2025, though. Now, households above 400% of the poverty level get no tax credit. Here are the 2027 lines.| Household size | 138% (Medicaid line) | 400% (subsidy cap) |
|---|---|---|
| 1 person | $22,025 | $63,840 |
| 2 people | $29,863 | $86,560 |
| 3 people | $37,702 | $109,280 |
| 4 people | $45,540 | $132,000 |
Based on 2026 federal poverty guidelines used for 2027 coverage. Below 250%? Silver plans with cost sharing reductions can slash your deductible. Above 400%? Our ACA subsidy cliff guide shows ways to qualify again.
