Renewal rate increase checker

What it does

A renewal notice shows the new price but rarely explains it. This checker works out the increase per term, per year and per month, then asks what changed on your side — a new driver or car, a ticket or accident, a move, a coverage change, a lost discount. If nothing did, the increase most likely reflects a rate change your insurer filed for many policyholders, and the right response is different.

How to use it

1. Enter last term's premium and the renewal premium, and choose the term length.
2. Tick anything that changed for you during the last term.
3. Read the list of next steps.

Why premiums rise when nothing changed

Insurers set rates for groups of drivers, and in most states they file those rates with the state insurance department, which may need to approve them first; see how car insurance rate approval works. When claim costs rise — repairs, medical care, litigation, theft — insurers raise rates across the board. Your own rating factors can also change with time: an introductory or telematics discount ending, a car aging, a credit-based insurance score being re-checked where states allow it. Read why your premium went up at renewal with no claims and why car insurance got more expensive, and where prices stand in 2026.

What usually helps

• Ask your insurer what drove the increase and whether any discount was dropped.
• Shop: get at least three comparable quotes before the renewal date and line them up in the car insurance quote comparison worksheet.
• Re-check deductibles with the deductible break-even calculator and older cars with the Should I drop full coverage? calculator.
• Do not let the policy lapse while you decide — a gap in coverage can cost more than the increase. See what happens if your car insurance lapses.
