Part of the Car Insurance After Accident reference, which uses Wrenfield Auto Insurance (a fictional example) to illustrate car insurance after an accident criteria.

What goes into the total?

The real price of car insurance after accident claims is more than the first number on a quote. Take the premium for the full policy term and convert every quote to the same period. Check that each quote includes the same coverages, because a low figure can reflect less protection. The NAIC explains that premiums depend on how much coverage a driver buys, and that dropping optional coverage or choosing a higher deductible can lower them. Those are changes in what you bought, not savings on the same thing.

Next, record the deductible for each coverage. A deductible is the part of a collision or comprehensive loss you pay yourself before the insurer pays. The NAIC says that amounts of $250, $500 and $1,000 are typical, and that a higher deductible generally means a lower premium. Write the deductible next to the premium so that the trade is visible on one line.

Test the deductible against your savings

The NAIC says to raise a deductible only if you could cover it when you file a claim. After an accident this deserves an honest look, because you may have just paid one. Compare the premium saved in a year with the extra amount you would owe in a single claim, then decide how many claim-free years it would take for the higher deductible to pay for itself.

For older cars, the arithmetic can point the other way. The NAIC suggests considering whether to drop physical damage coverage on older vehicles, unless a lienholder such as a bank requires it. Compare the yearly cost of collision and comprehensive with what the car is actually worth, after the deductible. If your car was recently repaired, use its value now and not what you remember paying for it.

Run it again for renewal

Ask each insurer whether your accident is already reflected in the quote or could change the price at renewal. A cheap first term that rises at renewal may cost more than a steadier one. Include the cost of any overlap between old and new policies, and any refund due from your old one.

Finally, ask about discounts, but enter them only once confirmed. The NAIC says discounts may be available for multiple vehicles, safety or anti-theft devices, low mileage and bundled policies, and that availability varies by state.

How do you model a surcharge over several renewals?

Ask each insurer to state any accident surcharge in dollars for each coverage, and then list every renewal at which the accident could still count. Where your state sets a limit, use it: Maryland's regulator says accidents more than three years old cannot be used to raise your rate. Where it does not, ask the insurer how long it looks back and whether the charge ends automatically.

Surcharges do not always scale with the damage. New York's regulator says surcharges apply to liability, collision and no-fault coverages, and that the amount paid on a claim does not change the surcharge, so a $3,000 loss and a $50,000 loss result in the same one. That means the size of your last repair bill may tell you very little about your next premium. Build the sum from the insurer's stated figures, not from the cost of the accident.

Allow time to act. Maryland says insurers must mail a renewal increase notice at least 45 days before the renewal takes effect, and other states have their own rules. Put your renewal date in a calendar and start collecting quotes well before it.
