Car Insurance Deductible Calculator
Picking a deductible is a bet on your future claims. Compare three deductibles side by side over 10 years — premiums, claim costs, and the premium surcharge after a claim that most calculators ignore — and see the real break-even point on a chart.

Worked example: $500 vs $1,000
Deductible $500 at $1,800/yr versus deductible $1,000 at $1,500/yr.
Annual savings with the higher deductible: $300. Extra risk per claim: $500.
($1,000 − $500) ÷ ($1,800 − $1,500) = $500 ÷ $300 = 1.67 years
Break-even is about 20 months. Go 20+ months without a claim and the $1,000 deductible wins. File a claim sooner and the $500 deductible wins — and that is before the claim surcharge, which punishes the frequent filer twice: once at the repair shop, once on every premium after.
Which deductible should you choose?
A higher deductible makes sense when…
- You have a solid emergency fund — the deductible would be a dent, not a crisis.
- You rarely file claims. Five-plus claim-free years is a strong signal.
- Your car is older and worth less, so a big repair bill is less likely to make sense anyway.
A lower deductible is smarter when…
- Paying $1,000 tomorrow would strain your budget or force you onto a credit card.
- You drive a lot, park on the street, or have teen drivers in the house.
- Your lender or lease agreement requires it — many cap deductibles at $500 or $1,000.
Collision vs comprehensive: split them
You do not have to use the same deductible for both coverages. A common split is $1,000 collision and $250 comprehensive — accidents you cause are rarer, while glass, theft, hail, and animal claims are common and cheap to trigger. Ask your insurer to price the split; it often beats a single middle number.
Financed or leased cars
Lenders and lease companies usually cap your deductible — commonly $500, sometimes $1,000 maximum. Check your loan or lease agreement before raising it. Go over the cap and you can breach your contract, which gives the lender an excuse to force-place expensive insurance on you.
Deductible FAQs
What is a car insurance deductible?
The amount you pay out of pocket on each claim before your insurance pays the rest. If you have a $500 deductible and a $3,000 repair, you pay $500 and the insurer pays $2,500. It applies per claim and per coverage — collision and comprehensive each have their own.
How do I choose the right deductible?
Balance the premium savings against what you can actually pay. The practical rule: pick the highest deductible you could pay tomorrow from savings without stress. Then use the calculator above to check whether the premium savings beat the extra risk over 10 years.
Does a higher deductible always save money?
No. It saves money only if you stay claim-free long enough to pass the break-even point. One early claim can wipe out years of premium savings — and the premium surcharge after a claim hits frequent filers hardest, which is exactly what the chart above shows.
What happens if I can’t pay my deductible?
The insurer will not pay its share until you pay yours, so your repair stalls. Some shops offer payment plans, but that is not guaranteed — and a lender can penalize you for letting required repairs slide. Never choose a deductible above what you have in savings.
What is a disappearing (vanishing) deductible?
A policy feature that shrinks your deductible — often by about $100 — for each claim-free year, usually up to five years. It rewards safe drivers and softens the risk of a high deductible. Toggle it on in the calculator to see the adjusted math.
Will my premium rise after I file a claim?
Usually yes. An at-fault claim commonly raises premiums 20–40% for three to five years. That surcharge is a real cost of filing — on a $1,800 policy, a 20% hike costs an extra $360 a year. Small claims near your deductible are often cheaper to pay yourself.
