Why These Three Numbers Matter
Every insurance policy is built around financial risk-sharing between you and your insurer. Three figures govern how that risk is divided: the premium, the deductible, and the out-of-pocket maximum. Together, they set the floor and ceiling of what you'll spend—before a claim and during one.
Many policyholders focus almost entirely on the premium because it's the most visible cost. But treating a policy as just a monthly bill without understanding the other two numbers can lead to real financial surprises when a claim actually occurs. This article explains each term, how the three figures interact, and what trade-offs to be aware of when comparing policies.
For a broader introduction to insurance vocabulary, see our plain-language insurance glossary. And for context on how policies are structured overall, the Insurance Types hub covers major categories you're likely to encounter.
| Premium frequency | Monthly, quarterly, or annually |
| Deductible reset period | Typically annual (per policy year) |
| Out-of-pocket max includes | Deductible, copays, and coinsurance for covered services |
| Out-of-pocket max excludes | Premiums and costs for non-covered services |
| Premium–deductible relationship | Higher deductible generally means lower premium |
| After out-of-pocket max is met | Insurer covers 100% of additional covered costs for that period |
The Premium: Your Ongoing Cost of Coverage
The premium is the amount you pay—monthly, quarterly, or annually—to keep your policy active. Think of it as the price of being covered at all. Even if you never file a claim, you owe the premium.
Premiums are calculated based on risk factors that vary by insurance type. For health insurance, those include age and geographic location. For auto insurance, driving history and vehicle type play a large role. For homeowners insurance, factors like location, construction materials, and claims history matter.
A lower premium can be appealing, but it almost always comes with trade-offs elsewhere in the policy—typically a higher deductible or less generous coverage limits. Understanding this relationship is essential before selecting a plan.

The Deductible: What You Pay First
The deductible is the dollar amount you must pay out of your own pocket for covered losses before your insurer begins contributing. If your health insurance deductible is $1,500 and you incur $2,000 in covered medical costs, you pay the first $1,500 and the insurer covers the remaining $500 (subject to any cost-sharing that applies afterward).
Deductibles reset on a schedule—most commonly at the start of each policy year. Some policies carry separate deductibles for specific coverage types; for example, a homeowners policy may have a standard deductible for most claims and a separate, higher percentage-based deductible for wind or hail damage.
Generally, higher deductibles lower your premium, and lower deductibles raise it. This is the core trade-off: you accept more financial exposure per claim in exchange for reduced ongoing costs. For more on how deductibles interact with copays and other cost-sharing features, see how deductibles, premiums, and copays work together.
Premium
The regular payment made to an insurer to keep a policy in force, regardless of whether any claims are filed. It is typically billed monthly, quarterly, or annually.
Deductible
The amount a policyholder must pay out of pocket for covered losses before the insurer begins paying. Deductibles usually reset at the start of each policy period.
Out-of-Pocket Maximum
The maximum amount a policyholder can be required to pay for covered services in a policy period. Once reached, the insurer covers 100% of additional covered costs.
Coinsurance
A cost-sharing arrangement where the policyholder pays a set percentage of covered costs after the deductible is met, and the insurer pays the remainder. For example, 80/20 means the insurer pays 80% and the policyholder pays 20%.
Copay
A fixed dollar amount a policyholder pays for a specific covered service, such as a doctor visit, at the time of service. Copays may or may not count toward the deductible depending on the policy.
The Out-of-Pocket Maximum: Your Financial Safety Net
The out-of-pocket maximum (sometimes called the out-of-pocket limit) is the most your insurer can require you to pay in covered costs during a single policy period. Once you reach this threshold—through your deductible, copays, and coinsurance combined—the insurer covers 100% of additional covered expenses for the rest of that period.
This number is your protection against catastrophic costs. Without it, a serious illness or major accident could mean unlimited personal liability. Federal law requires most health insurance plans to cap out-of-pocket costs for essential health benefits, though specific limits are updated periodically by regulators.
It's important to note that premiums do not count toward your out-of-pocket maximum. Costs for services not covered by your policy also don't count. Only amounts you pay for covered services—deductible, copays, coinsurance—typically apply. Always read your policy's definition section to confirm what counts and what doesn't. For related nuances, understanding policy limits versus coverage limits is worth reviewing as well.
