Should I always file a claim for a minor scratch?

Not necessarily. If the repair cost is only slightly higher than your deductible, the potential increase in your future premiums (especially if you are at fault) may exceed the insurance payout over 3 years. This tool helps you calculate that trade-off.

Is this tool specific to ICBC (British Columbia)?

While the 'Roadmap' and 'ROI' logic are initially tailored for ICBC policies, the calculator allows you to input custom deductible and premium values, making it useful for users in other regions as well.

How does the ROI calculator estimate premium hikes?

It uses common insurance step-models (like ICBC's claim-rated scale) to estimate how many 'steps' you might drop after an at-fault accident and the resulting percentage increase in your basic and optional premiums.
