A quote is not a price for you. It is a price for a specific set of coverages, calculated from information you supplied and not yet verified.
That definition explains almost everything people find confusing about quotes: why they differ so much between companies, why they change between quoting and buying, and why comparing them is harder than comparing the headline numbers.
What a quote actually is
Each insurer files a rating formula with the state. That formula takes inputs, weights them according to that company's own view of risk, and produces a premium.
Because each carrier files its own formula and weights inputs differently, the same driver gets materially different prices from different companies. This is not one company being greedy and another being generous. It is genuine disagreement about how much a two-year-old speeding ticket or a particular vehicle should cost to insure.
That disagreement is the entire reason shopping works.
What you need to get an accurate one
Gather these before you start. Guessing is what produces a quote that changes later.
About the drivers:
- Full name, date of birth and driver licence number for every licensed driver in the household, including teens with permits
- How long each has been licensed
- Any tickets, at-fault crashes or claims in the past three years, with dates
- Any licence suspension, and whether an SR-22 filing is involved
About the vehicles:
- The VIN for each vehicle, which is the single most useful item because it decodes the exact trim, engine and safety equipment
- Year, make, model
- Roughly what you drive annually
- Whether it is owned outright, financed or leased
- Any anti-theft or safety equipment
About the situation:
- The garaging address, meaning where the car sleeps. This is what carriers rate on, not where you work.
- Whether the vehicle is parked in a garage, a driveway or on the street
- Your current declarations page, if you have one
That last item is the one people skip and the one that matters most for comparison. The declarations page lists your actual limits, deductibles and endorsements. Without it, you are quoting against a guess about your own policy.
Why the price changes at binding
A quote is self-reported. Binding is verified.
When you move to buy, the carrier pulls your motor vehicle record and checks the vehicle details. The three usual causes of a change:
A violation you forgot or misdated. Tickets are easy to misremember by a year, and a year matters when the rating window is three.
The wrong trim level. "A Subaru Outback" covers a wide range of engines, drivetrains and safety packages that rate differently. This is why the VIN matters.
An undisclosed household driver. Carriers expect everyone in the household with regular access to be listed. Leaving someone off produces a cheap quote and an expensive correction, or worse, a claim dispute later.
None of this is a bait and switch. It is the difference between an estimate and a price.
How to compare quotes properly
The mistake is comparing prices instead of comparing policies. A quote that comes back dramatically cheaper has usually left something out.
- Decide your coverage first. Limits, deductibles, and whether you need comprehensive and collision. Write it down.
- Quote that identical package everywhere. Same liability limits, same deductibles, same endorsements.
- Give the same information every time. Inconsistent inputs produce quotes that cannot be compared.
- Read each quote back line by line. Bodily injury limits, property damage, PIP, uninsured motorist, comprehensive deductible, collision deductible.
- Ask what is included that you did not request, and what was excluded that you did.
- Ask about renewal. Some carriers lead with a low first-term premium containing credits that expire. Ask directly whether the quoted rate is introductory.
Buying without an agent
You can, easily, and for a straightforward situation it is often the fastest route. A clean record, one car, one driver, standard coverage: quote online, buy online, done in twenty minutes.
Where doing it alone costs you is when the situation is not straightforward:
- You need an SR-22 filing. Several carriers decline these outright, and you find out one rejection at a time.
- You have a DUII, multiple violations, or a lapse. The non-standard market is not sold the way the standard market is, and the price spread between carriers for the same record is wide.
- You drive rideshare or delivery. Only some carriers offer an endorsement, and fewer cover delivery as well as passengers.
- You are adding a teen. Which parent holds the policy and which vehicle the teen is assigned to changes the number materially, and those are judgement calls rather than form fields.
A form cannot ask a follow-up question. That is the actual difference.
What a quote is not
It is not coverage. Coverage exists when the carrier issues a policy and it takes effect. Never cancel an existing policy on the strength of a quote. Bind the new one first, with a start date on or before the old end date, then cancel.
It is not a guarantee. The carrier can decline to write you after verification.
It is not indefinite. Quotes typically last around 30 days and carriers revise their filed rates regularly.
The short version
A quote is an estimate for a defined package of coverages, priced by one company's view of risk. Gather the VINs, the licence numbers, the dates of any violations and your current declarations page before you start, and quote the identical package at every carrier.
Get the information right and the quotes hold. Guess at it and you are comparing four numbers that do not mean the same thing.
