Insurance Deductible Calculator
Calculate the break-even point to decide if you should switch to a high deductible auto insurance plan to save on premiums.
Direct Answer
If you have enough emergency savings to cover the higher deductible, it usually pays off to take the high deductible and pocket the premium savings.
Option A (Low Deductible)
Option B (High Deductible)
Break-Even Analysis
Stick with the low deductible. It takes too long (over 3 years) to break even on the premium savings.
Step by step
How to use this tool
- 1
Get two quotes from your insurer: one with a $500 deductible and one with a $1,000 deductible (or your current vs proposed amounts).
- 2
Enter the monthly or annual premium for each option.
- 3
Enter each deductible amount.
- 4
Review the break-even period. If you can go that many months without a claim, the higher deductible saves money. If you tend to file 1+ claims per year, keep the lower deductible.
