Tip. If you rarely claim, the higher deductible usually wins on cost. The question is whether you can absorb it.

Assumptions

  • The extra premium for the lower deductible has to be earned back through smaller out-of-pocket costs on claims.
  • Claims to break even = the annual premium gap ÷ the deductible gap, in a single policy year.
  • Assumes each claim is large enough to exceed both deductibles.
  • Ignores how claims affect future premiums, which often matters more than the deductible itself.
  • Estimate only. Real policies add exclusions, sub-limits, waiting periods, and network rules that this page does not model.

Start with a scenario, then read the response curve to see which input actually moves the answer.

Example 1

Typical auto or home choice

A $2,000 deductible gap bought with $400 of extra premium.

Extra premium to earn back

$400

Example 2

Cheap coverage upgrade

A small premium difference for a large deductible drop, which pays off with one claim.

Extra premium to earn back

$120

Example 3

Expensive coverage upgrade

The lower deductible costs so much more that it needs multiple claims a year to justify.

Extra premium to earn back

$900

Sweeps annual premium (low ded.) from half to one and a half times your value, holding everything else fixed.

What this calculates

Compares a high-deductible, low-premium policy against a low-deductible, high-premium one, and shows how many claims a year it takes for the richer coverage to earn back its extra premium.

How to use it

  1. Start with high deductible and work down the form, or load an example to begin from a realistic case.
  2. Read the headline result alongside the supporting rows, which show the intermediate figures behind it.
  3. Check the assumptions. They decide what the number includes and, more importantly, what it leaves out.
  4. Sweep annual premium (low ded.) on the response curve to see how much it actually moves the answer.
  5. Run a cautious case as well as an optimistic one before using the estimate in a decision.

Common mistakes

  • Picking a deductible you could not cash-flow if a claim hit tomorrow.
  • Ignoring that a claim on the low-deductible policy may raise future premiums anyway.
  • Comparing deductibles across policies with different coverage limits or exclusions.

Formula

Claims to break even = annual premium gap ÷ deductible gap

Inputs

  • High deductible
  • Low deductible

FAQ

What if I claim once every few years?

Annualize it. One claim every three years is about a third of a claim a year, so if the break-even needs more than 0.33 claims a year the high deductible is the better bet.

Should I always take the highest deductible I can afford?

Affordability is the constraint that matters. A deductible you could not pay tomorrow without borrowing turns a covered loss into a debt problem, whatever the premium math says.

Does claiming affect my premium?

Usually yes, and often for several years. That effect can easily exceed the deductible difference, which is a strong argument for a high deductible and not claiming for small losses.

How do I choose between a high and a low deductible?

Compare the premium saving with the extra risk. If you can pay the higher deductible from savings without strain and you claim rarely, the high-deductible option usually wins on expected cost.

What is a good deductible for car insurance?

$500 and $1,000 are the most common choices. Moving from $500 to $1,000 typically cuts the premium by 10 to 20%, which is worth it only if you can actually pay $1,000 if you crash.

Will a higher deductible reduce my premium enough to matter?

Usually yes. The gap between deductible levels is often several hundred dollars a year, and this calculator shows how many claims the lower deductible would need to justify itself.
