Car Insurance Calculator
Most “car insurance calculators” pretend to hand you a price from a few inputs. That isn’t possible — your price comes from an insurer’s private model. This calculator does the part that’s both honest and useful: it helps you choose the right coverage limits to carry, based on what you need to protect.
How much auto coverage should you carry?
Liability limits should protect what you own — a serious at-fault crash can put your assets at risk. This worksheet recommends limits and whether to keep comprehensive/collision.

- Uninsured-motorist (UM/UIM)match
- Comprehensive & collision—
How these are chosen
<$50k → 50/100/50 · $50k–100k → 100/300/100 · $100k–500k → 100/300/100 · $500k–1M → 250/500/100 · ≥$1M → 250/500/250 + umbrella.
Comp/collision: often worth dropping when the car’s value is under ~$4,000, since payouts are capped at value minus deductible. State minimums are usually far too low — these are coverage guidelines, not a quote.
Why an honest calculator focuses on coverage, not price
It’s worth being clear about what this tool deliberately does not do: it doesn’t invent a price. The reason is simple — no website can know your insurer’s rating model, your exact territory loss data, your credit-based insurance score (where used) or how a given company weighs your specific car and history. Tools that show a precise figure after three questions are marketing, not math. What genuinely helps you is deciding how much coverage to carry, because that’s the decision you control and the one that determines whether you’re actually protected. Once you know your target limits, you can collect real quotes and compare them fairly.
What the calculator recommends and why
- Liability limits sized to your net worth. Liability pays for the harm you cause others; if it runs out, your assets are exposed. The tool tiers your recommended limits from your assets minus debts.
- Matching uninsured/underinsured-motorist coverage. So you’re as protected when hit by an uninsured driver as you are when at fault.
- A comprehensive/collision decision. Based on your car’s value — keep them while the car is worth enough to matter, reconsider them once it isn’t.
A worked example
Imagine $300,000 in assets, $80,000 in debt and a car worth $18,000. Net worth is $220,000, so the tool recommends 100/300/100 liability with matching UM/UIM, and — because the car is worth well over the ~$4,000 threshold — advises keeping comprehensive and collision. Now you know the coverage to request, and you can take those exact limits to several insurers to compare quotes on equal footing.
Understand what drives the cost
Pair your coverage decision with a clear understanding of what moves the cost so you can judge any quote you receive. The big factors are your coverage level, your vehicle, your location, your age and experience, your driving record, and your credit-based insurance score (in most states). Our guides cover each in plain English: how much car insurance is, what affects car insurance cost, why your ZIP code matters, and how your car model affects the cost. Together they help you tell whether a quote is reasonable.
From coverage to a real quote
Treat the calculator’s output as your shopping list. Take the recommended limits and your chosen deductible to several insurers and request quotes on identical terms — the only way to compare price honestly, since each company prices the same driver differently. If your net worth is high, add an umbrella policy for liability beyond your auto limits. The result is coverage that actually fits your life, bought at a price you’ve verified against the market. This tool gives a coverage recommendation for general guidance, not a price or a quote.
Frequently asked questions
Can a car insurance calculator tell me my price?
No. Any tool that promises an exact price from a handful of questions is guessing. Real prices come from insurer rating models using dozens of factors. This tool calculates the coverage you need so you can request accurate quotes.
How does this car insurance calculator work?
You enter your assets, debts and your car’s value. It recommends liability limits sized to protect your net worth, suggests matching uninsured-motorist coverage, and advises whether comprehensive and collision are still worth carrying on your car.
What affects how much car insurance costs?
Your coverage level, vehicle, location, age, driving record and (in most states) credit-based insurance score. See our guide to what affects car insurance cost.
How do I actually get a price?
Decide your coverage with this tool, then request quotes from at least three insurers on identical limits and deductibles. Comparing like-for-like is the only way to find your real price.
Is the result a quote?
No. It’s a coverage recommendation. It is not an offer of insurance or a personalized price.
