What Is a Deductible?

The short version

A deductible is the amount you pay for covered health care each year before your insurance starts paying its share. If your deductible is $3,000, you pay the first $3,000 of covered services yourself; after that, the plan begins picking up most of the bill through coinsurance or copays.

Deductibles reset every plan year. Preventive care — like an annual checkup or many screenings — is typically covered for free even before you meet your deductible, which is a deliberate design choice to keep people from skipping care that catches problems early.

How the deductible fits with your other costs

Your deductible is one of four numbers that determine what you actually pay: the premium (your monthly bill), the deductible (what you pay before the plan helps), coinsurance or copays (your share after the deductible), and the out-of-pocket maximum (the annual cap on your spending). These move together — plans with low premiums usually have high deductibles, and vice versa.

That trade-off is the heart of choosing a plan. A healthy person who rarely needs care may prefer a low premium and accept a high deductible, betting they will not hit it. Someone managing a chronic condition often prefers a higher premium and a lower deductible, because they know they will use care and want the plan paying sooner.

A quick example

Say you have a $3,000 deductible and 20% coinsurance, and you need a $10,000 procedure. You pay the first $3,000 (the deductible), then 20% of the remaining $7,000 ($1,400), for $4,400 total — unless that amount would push you past your out-of-pocket maximum, in which case the plan covers the rest.

This is why the deductible alone never tells the whole story. Use an out-of-pocket estimator that combines premium, deductible, coinsurance, and the out-of-pocket maximum to see your real cost in both a healthy year and a bad one.

Frequently asked questions

Do I pay the deductible all at once?

No — you pay it as you use care, until your covered spending for the year adds up to the deductible amount. Then the plan starts paying its share.

Does the deductible include my premium?

No. Premiums are separate and never count toward your deductible or out-of-pocket maximum.
