By Alex Diaz · How we calculate this
A single at-fault accident or DUI conviction can raise premiums 40-100% for three to five years afterward, which makes your own driving record one of the largest cost levers you actually control, more so than the car you drive or the coverage you choose. This calculator weighs the monthly premium you enter against your income and any existing debt.
These key factors affect car insurance affordability
What drives your premium
Your driving record, age, location, vehicle make and model, and annual mileage all significantly affect your premium, and in most states so does a credit-based insurance score pulled from your credit history rather than your driving history, though California, Hawaii, Massachusetts, and Michigan all ban that practice outright. None of those factors moves the needle as much as a single at-fault accident or DUI conviction, though, which can raise rates 40-100% for three to five years afterward.
Coverage level trade-offs
State-minimum liability-only coverage is cheapest but leaves you exposed if your own car is damaged. Full coverage, which adds comprehensive and collision, costs more but is typically required if you're financing or leasing the vehicle. If you're financing or leasing with little equity built up, it's worth asking about gap insurance too, since comprehensive and collision only pay out the car's depreciated value, not what you still owe on the loan.
Bundling and discounts
Insurers commonly offer meaningful discounts for bundling home or renters insurance with auto, maintaining a clean driving record, driving low annual mileage, good student grades for young drivers, and enrolling in usage-based telematics programs that track how you actually drive.
How to use your results
- If your premium is pushing your score into risky territory, get quotes from at least three insurers, since premiums for identical coverage can vary by hundreds of dollars a year between companies.
- Check whether raising your deductible from $500 to $1,000 lowers the premium enough to matter, as long as you'd have that deductible amount available if you needed to file a claim.
- Review your coverage level against your car's actual value - carrying comprehensive and collision on an older, low-value car sometimes costs more annually than the payout would be worth.
Ways to make car insurance more affordable
- Bundle auto with renters or homeowners insurance through the same carrier, which commonly saves 10-25% on the auto policy.
- Ask about usage-based or telematics programs if you're a low-mileage or careful driver - they can meaningfully cut premiums for the right driving profile.
- Raise your deductible if you have emergency savings to cover it, since moving from a $500 to $1,000 deductible often lowers premiums 10-15%.
- Shop your policy at renewal every year rather than auto-renewing, since loyalty rarely earns better pricing in auto insurance.
