FAQ

What is disability insurance?

Disability insurance replaces part of your income if illness or injury prevents you from working. It ensures bills and living expenses remain covered while you recover.

How do I calculate my coverage needs?

This tool subtracts your existing coverage from your monthly income so you can see how much additional protection you may want to buy.

Formulas

Recommended Coverage: Monthly Income - Existing Coverage

We treat the remainder as the amount of income that still needs protection after accounting for the coverage you already have.
