The formula

How this number is built

premium = base rate × age × record × deductible × limits × mileage × credit × bundle
Step by step

Doing it by hand

Step 1

Start from a real quote for your ZIP code rather than a national average.

Step 2

Enter every ticket and at-fault claim from the last three years — carriers see them all.

Step 3

Test each deductible level; the saving from $500 to $1,000 is usually the best value step.

Step 4

Do not cut liability limits to save money; that is the coverage that protects your assets.

Step 5

Re-run this at renewal, since one factor changing can justify shopping the policy.

Questions

What people ask next

Why does credit affect my premium?

Most states permit credit-based insurance scores because they correlate with claim frequency. A few states prohibit the practice.

How much liability coverage is enough?

A common rule is enough to cover your net worth, since anything above your limits is your personal exposure.
