Two drivers can pay vastly different premiums for the same coverage. Insurers use dozens of factors to set rates. Understanding which matter — and which you can change — helps lower your premium. This guide covers them all.

Major Rate Factors

Factor	Impact
Driving record	Major (30–50%)
Credit score (most states)	Major (20–40%)
Age	Major (varies by stage)
Location	Major (urban vs rural)
Vehicle	Major (value, type, theft rate)
Coverage limits	Direct
Deductible	Direct (lower deductible = higher)
Annual mileage	Moderate
Marital status	Minor to moderate
Gender (some states)	Minor
Continuous coverage	Moderate

Driving Record

Most influential factor:

Item	Premium Impact (3–5 yrs)

Multiple violations	+30% to +75%

Tickets typically affect rates for 3 years; major violations for 5+.

Credit Score (Where Allowed)

Used in most states (not California, Hawaii, Massachusetts, Michigan):

Very good (740–799)	1.05×
Good (670–739)	1.15×

Improving credit score can lower premium dramatically.
