While Obamacare plans have to comply with the guidelines mentioned above, they do come in a few different forms to accommodate where you are in life. After all, your healthcare needs will change along with you. For example: As you make career moves, your finances shrink or expand, when you turn 26 and age off your parent's health insurance, if you decide to start a family, or as your health status stays strong or enters periods that require more medical attention.

In general, the lower the premium, the higher the deductible, and vice versa. That means your household budget and typical healthcare needs come into play. Maybe you're relatively healthy and want to keep your monthly premium costs low, then a bronze plan may feel like the right choice. Or perhaps you have ongoing health concerns that require more frequent care and prescription medications, then a gold plan with a lower deductible may feel more comfortable. If you qualify for cost-sharing reductions, you'll want to choose a silver plan that can have an actuarial value as high as 94%.

There are also catastrophic plans, which are available to individuals under 30 or those who have a hardship or affordability exemption, regardless of age. These plans offer a lower monthly premium but come with a higher deductible ($8,550 in 2021). They don't qualify for ACA subsidies, though. That means you may want to consider a plan in one of the metal categories if you're eligible for a subsidy—your premium and deductible could potentially be less.

ACA health insurance plans are categorized into what are known as the metal levels according to their actuarial values. On average, it works out as follows:

Bronze

You pay 40%, the insurance company pays 60% (on average)

Silver

You pay 30%, the insurance company pays 70% (on average)

Gold

You pay 20%, the insurance company pays 80% (on average)

Platinum

You pay 10%, the insurance company pays 90% (on average)
