Free Insurance Deductible Savings calculator with clear step-by-step results.
Raising a deductible trades a certain premium saving against an uncertain out-of-pocket cost. Multiplying the additional exposure by claim probability gives its expected value, and the years-to-fund figure answers the practical question: how long you must go claim-free before the higher deductible is genuinely paid for.
Expected benefit
Benefit = premium saving - (higher deductible - current deductible) x claim probability
Years to fund
Years = additional exposure / annual premium saving
Not insurance advice. Policy terms, per-claim versus aggregate deductibles and regulatory requirements vary. Confirm the exact wording with your insurer before changing cover.
Your own history is the best guide. Broad averages are around 5-8% a year for home and 6-12% for auto collision, but they vary enormously by location and driver.
Only if you can absorb the higher deductible in cash without borrowing. Expected value ignores the risk of a bad year landing before the savings have accumulated.
