# What is car insurance rate?

> A car insurance rate is a pricing value an insurer uses to calculate premium for a particular risk.

Glossary date: March 23, 2026.

## How it works

The final premium combines approved rating factors with your coverage selections and insurer rules. Factors vary by state and company.

## Example

Changing a garaging address or adding a driver changes the information used to calculate the policy premium.

## Why it matters

A rate is part of the calculation, while the premium is the amount charged for the policy.

## What to check on your policy

Confirm that every driver, vehicle, use, address, and annual mileage estimate is accurate before accepting a price.

Coverage, definitions, limits, and legal requirements vary by policy and state. Your declarations page and policy forms control your coverage.
