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
- 1Enter your gross monthly income.
- 2Set the percent of income to replace (60–70% is typical).
- 3Enter any existing coverage you have through work.
- 4Set a premium rate to estimate the monthly cost of closing the gap.
The formula
- benefit
- — Recommended monthly benefit = income × replacement%
- gap
- — Coverage gap = max(0, benefit − existing)
- premium
- — Annual premium = gap × 12 × premium rate
Worked example
The scenario
$6,000/month income, 65% replacement, $0 existing coverage, 2% premium rate.
The result
Recommended benefit: $3,900/month. Coverage gap: $3,900/month. Estimated premium: ~$78/month.
Common use cases
- Workers without (or with limited) employer long-term disability coverage.
- Self-employed professionals who have no employer safety net.
- High earners whose income far exceeds typical group coverage caps.
Limitations & assumptions
- Premiums vary widely by occupation, age, health, and policy features (own-occupation, COLA riders).
- Does not distinguish short-term vs long-term disability or elimination periods.
- Group/employer benefits may be taxable, changing the replacement percentage you need.
