Millions of Americans may be worse off under the House Republican bill to replace the Affordable Care Act. But some, particularly those who are wealthier, may actually fare better.

Below are some examples of how the proposal’s effects could play out.

Better under new plan

You are a 50-year-old single man in Illinois who owns a plumbing business and makes $75,000 a year.

You would get more in tax credits under the Republican plan.

You would qualify for $3,500 in tax credits to help pay your insurance premium; at your income, you would have gotten no financial help from Obamacare.

The Republican plan, named the American Health Care Act, offers tax credits based on age for people earning that kind of income or less. Obamacare cuts off financial assistance for upper-middle-class people. The Republican plan offers more help further up the income scale.

Better under Obamacare

You are 35 and do intermittent construction work in Indiana. You have been insured through Medicaid since your state expanded eligibility.

There’s a chance you may eventually lose Medicaid coverage.

You didn’t have health insurance before Obamacare. Before Indiana extended Medicaid to adults earning up to 138 percent of the poverty level, about $16,000 for a single person like you, you could never afford insurance with your earnings.

Under the Republican plan, you may be able to keep this coverage, but because federal funding to states will be substantially reduced in 2020, you will eventually be at the mercy of the state budget. Indiana may stop offering Medicaid to people like you, or may pare back the medical services it offers.

The new plan gives you another option: If you lose Medicaid, you will qualify for a $2,500 tax credit to buy your own insurance based on your age. But it may not cover enough of the cost of your insurance premium. And you also could not get additional help with deductibles or co-payments. In general, the Republican plan is much less generous to people like you who are lower on the income scale.

Better under Obamacare

You are a 28-year-old who was recently laid off from a higher-paying job, and now make $20,000 as a barista in California.

You would receive less in tax subsidies and could be penalized for having a lapse in coverage.

If you were a little younger, you might be able to go on your parents’ health plan. Obamacare allows adult children to stay in a family plan until age 26, and the Republican plan wouldn’t take that away.

But since you are 28, you could instead get $2,000 toward your insurance premium under the Republican plan. That’s substantially less than what you’d receive under Obamacare; your low income would qualify you for substantially more assistance.

Under Obamacare, you would qualify not just for help buying insurance, but also for additional subsidies to lower your co-payments and deductible. The Republican proposal would eliminate that second kind of financial help.

You would need to find a way to pay for insurance soon, because you could be penalized for a gap in coverage of longer than two months. Anyone who drops coverage would be charged 30 percent more, for up to a year, compared with someone who never had a coverage lapse.

Better under new plan

You are a 40-year-old lawyer with two children who makes $250,000 a year at a New York City law firm.

You would be able to save more money tax-free.

You have very generous employer health coverage. The Republican plan would postpone enactment of a looming tax on health plans like yours, making it less likely your employer would cut back. It would also allow you to save twice as much money each year, tax-free, in a health savings account — up to $13,100 starting in 2018.

You’d also get a tax break on your wages and on any investment income. The Republican plan is much better than Obamacare for high-income people with employer-based coverage.

Better under Obamacare

You are a 45-year-old assistant store manager earning $34,000 at a retailer that provides health insurance in Washington State.

Your employer may stop offering coverage.

You currently have health insurance through work, in part because Obamacare required larger companies to provide affordable insurance or face penalties.

But the Republican plan would eliminate the penalties, which means that your company may be less likely to keep providing health insurance. Retail is an industry in which employers may be more likely to drop coverage, because labor costs are high and margins tend to be small.

If your employer dropped your coverage, you would qualify for a $3,000 tax credit to buy your own insurance. But you’d probably have to pay a lot more out of your own pocket for the entire premium than you pay now through your employer.

Outcome unclear

You are a 64-year-old married accountant with diabetes in Texas. Your household income is about $65,000, and you buy your own health insurance.

You would get more in tax credits but would most likely pay higher premiums.

Because you and your wife are both over 60, you will receive $8,000 in tax credits to pay your premiums. Under Obamacare, you qualified for a small subsidy because of your income, but the new plan offers you more financial help.

Nevertheless, you may not fare better over all under the Republican plan, because the price of your insurance would be substantially higher than it is under Obamacare.

Obamacare lets insurance companies charge 64-year-old customers like you only three times as much as the youngest customers. But the Republican plan would allow insurers to charge you five times the price for young adults. That means that only a small fraction of insurance shoppers in their 60s — only those in markets with unusually low premiums — will be better off.

Better under Obamacare

You are a single mother in Utah earning $47,000 a year. Your 6-year-old son has cerebral palsy and gets health insurance through Medicaid.

Your son risks losing services he needs through Medicaid.

Your son needs a lot of health services, and Medicaid picks up a lot of the bills. Utah did not expand Medicaid under Obamacare, but your son already qualified for services under the program’s provisions for “persons with disabilities.”

The Republican plan would change the way the program is financed for patients like your son. Beginning in 2020, the federal government would start paying fixed sums to the state every year, instead of a set percentage of your son’s medical bills.
