There is no one answer to this question because health insurance costs vary depending on a number of factors, including the type of insurance, the state you live in, your age, and your health. However, in general, health insurance is more expensive for people in their 20s than it is for people in other age groups. This is because young adults are more likely to be healthy and to need less medical care than older adults, so insurance companies charge them higher premiums to offset the costs of those who do need more care.
There are a few things you can do to reduce the cost of health insurance in your 20s. First, if you're healthy and don't need to visit the doctor often, you can choose a health insurance plan with a high deductible. This means you'll have to pay more out of pocket when you do need medical care, but your monthly premiums will be lower. You can also look for health insurance plans that offer discounts for young adults, such as lower rates for people who are enrolled in college.
