A premium is the regular amount you pay just to have an insurance policy, while a deductible is the amount you pay towards a claim before the insurer picks up the rest. Think of the premium as the membership fee and the deductible as the excess you cover first when something goes wrong.
The core difference
A premium keeps the policy running; a deductible is paid only when you make a claim.
- premium — the amount paid regularly for an insurance policy: Her car insurance premium went up after the accident.
- deductible — the amount a policyholder pays out of pocket before the insurer covers the rest: Her car insurance has a $500 deductible for accident claims.
How to tell them apart
A simple way to keep these straight: you pay the premium no matter what, whether or not you ever claim. You only pay the deductible when something actually happens and you file a claim. One is ongoing; the other is conditional.
The mix-up usually shows up when people are comparing insurance quotes and assume a cheaper premium is always the better deal, without checking whether it comes with a higher deductible attached.
