The Multi-Car Deductible Decision
You insure three cars on one New Hampshire policy. Each carries collision and comprehensive coverage. Each has its own deductible — the amount you pay before the carrier covers a claim. You're comparing a $500 deductible against a $1,000 deductible across all three vehicles, trying to figure out which structure saves money without leaving you exposed.
The confusion: most households assume deductibles work like the multi-car discount — one decision applied uniformly. They don't. Each vehicle on your policy can carry a different deductible, and the savings from raising one car's deductible depend on that car's value, not the policy total. The decision is per-vehicle, not per-policy.

$25,000 / $50,000 / $25,000
New Hampshire does not mandate liability insurance for all drivers but sets these minimums when coverage is carried or required: $25,000 bodily injury per person, $50,000 per accident, $25,000 property damage. Deductibles apply only to collision and comprehensive, not liability.

What a Deductible Actually Controls
A deductible is the dollar amount you pay out of pocket before your carrier pays a collision or comprehensive claim.
The deductible applies per claim, per vehicle. If two cars on your policy are damaged in separate incidents, you pay the deductible for each. If one car is totaled and another sustains minor damage in the same accident, you pay one deductible per vehicle. The policy does not pool deductibles across cars.
Raising your deductible lowers your premium because the carrier's maximum payout per claim drops. A $1,000 deductible means the carrier never pays the first $1,000 of any claim, reducing their exposure. That reduced exposure translates to a lower monthly cost. The savings compound when you insure multiple vehicles, but only if you structure the deductibles intentionally.
The blocker: you don't know whether to raise deductibles uniformly across all cars or selectively on high-value vehicles, and you can't tell which structure saves more without overpaying at claim time.
Per-Vehicle Deductible Structure
Start with the newest or highest-value vehicle on your policy.
Next, consider your household's claim history and financial position. If you can cover a $1,000 deductible on one car but not on all three simultaneously, raise the deductible selectively on the car least likely to be driven daily or most likely to be garaged safely. Many households raise deductibles on a third car used occasionally while keeping lower deductibles on the two primary commuter vehicles. The structure balances savings against the realistic chance you'll need to pay the deductible.

When Uniform Deductibles Make Sense
Uniform deductibles — the same amount across all vehicles — simplify the policy and make sense when all cars on your policy are similar in value and usage.
The risk: if one car is significantly older or lower in value, you may be overpaying for collision and comprehensive coverage on that vehicle entirely. At that point, many households drop collision and comprehensive on the low-value car and carry only the state's liability minimums, saving the premium entirely rather than adjusting the deductible.
New Hampshire's financial-responsibility rule means you are not required to carry collision or comprehensive at all unless a lienholder mandates it. If you own an older car outright and can replace it without a claim, dropping physical-damage coverage on that one vehicle while keeping it on the others is a valid structure. The multi-car discount still applies to the policy as long as all vehicles remain on the same policy.

How Deductible Changes Re-Rate the Policy
Changing a deductible on one vehicle re-rates that vehicle's portion of the policy, not the entire policy. If you raise the deductible on Car A from $500 to $1,000, Car A's collision and comprehensive premium drops. Cars B and C remain unchanged unless you adjust their deductibles separately. The multi-car discount applies to the new total, but the deductible change itself is isolated to the vehicle you modified.
This matters when you add a vehicle mid-term. The new car comes onto the policy with whatever deductible you select at the time of addition. If your existing cars carry $500 deductibles and you add a fourth car with a $1,000 deductible, the policy now has mixed deductibles. That's structurally fine — the carrier prices each vehicle independently and applies the multi-car discount to the sum. You are not required to match deductibles across cars.
Compare Carriers With Your Deductible Structure
Carriers price deductible changes differently. One carrier may offer a larger monthly savings for raising a deductible from $500 to $1,000 on a high-value vehicle; another may offer better savings for uniform deductible increases across all cars. The only way to see which structure saves you the most is to request quotes with your specific vehicle lineup and the deductible options you're considering.
New Hampshire households insuring multiple cars should compare at least three carriers with identical coverage limits and deductible structures. Specify the year, make, model, and garaging address for each vehicle, and request quotes with $500 deductibles on all cars, then $1,000 deductibles on all cars, then mixed structures if one vehicle is significantly newer or more valuable. The comparison shows you which carrier rewards your specific deductible decision most effectively.
