About Disability Insurance Needs Calculator

The Disability Insurance Needs Calculator evaluates your monthly essential living expenses against existing savings and employer group coverage, determining the individual disability policy benefit required to protect your income.

Formula & Mathematical Calculation

Monthly Income Shortfall = Essential Living Expenses - ( Group Disability Benefit × ( 1 - Tax Rate % ) ) - Other Passive Income

Calculation Example

Frequently Asked Questions

It starts with your essential monthly living expenses, subtracts your after-tax group disability benefit, and subtracts any other passive income. The remaining shortfall, floored at zero, is the amount of individual tax-free disability income you would need to maintain your lifestyle.

When an employer pays for a group disability plan, the monthly benefit is generally taxed as ordinary income. The calculator multiplies your group benefit by one minus your tax rate so the coverage comparison is done on an after-tax basis that matches how individual tax-free policies behave.

Enter the baseline costs you would still owe if you could not work, such as housing, food, insurance premiums, minimum debt service, and core utilities. The tool does not distinguish between needs and wants, so your result is only as meaningful as the number you feed it.

No. The result is a steady-state monthly coverage need. Real policies have elimination periods, benefit durations, and definitions of disability that affect when and how long you actually receive benefits, none of which are modeled here.
