What is the disability insurance calculator?

In short

Disability insurance typically replaces 60–70% of your income because benefits you pay for yourself are usually tax-free. On a $6,000/month income at 65% replacement, you'd need about $3,900/month in coverage, costing roughly $65–195/month depending on the policy.

Calculates how much disability coverage you need based on income replacement, your existing coverage gap, and the estimated monthly premium.

How to use this calculator

  1. 1Enter your gross monthly income.
  2. 2Set the percent of income to replace (60–70% is typical).
  3. 3Enter any existing coverage you have through work.
  4. 4Set a premium rate to estimate the monthly cost of closing the gap.

The formula

benefit=income×replacement%
gap=max(0,benefitexisting)
benefit = income × replacement%; gap = max(0, benefit − existing); premium = gap × 12 × rate
benefit
Recommended monthly benefit = income × replacement%
gap
Coverage gap = max(0, benefit − existing)
premium
Annual premium = gap × 12 × premium rate

Worked example
