How it works
disability insurance calculator takes your inputs and produces monthly benefit, total over benefit period, waiting period. See what a disability would do to your income — monthly benefit, total coverage over the benefit period, and the waiting period cost. You provide 4 inputs: Monthly income (currency, in dollars) (default: 5500 dollars); Benefit percentage (percent, in percent) (default: 60 percent); Benefit period (months, in months) (default: 120 months); Elimination period (number) (default: 13). The calculator returns 3 outputs: Monthly benefit (the primary result); Total over benefit period (a secondary output); Waiting period (a supplementary figure). Insurance is the mathematics of rare but catastrophic events. The right coverage amount depends on your assets, income, dependents, and risk tolerance — not on rules of thumb. This tool computes the actual figures so you can compare premiums against the expected value of protection. The underlying formula: Monthly benefit = Income x benefit% | Total = benefit x months With the default values, monthly benefit is computed from the interaction of every input field — change any one of them and the result updates immediately, so you can stress-test different scenarios without re-entering the whole form. Adjust the inputs to match your real financial situation. The defaults are realistic starting points, but every person's circumstances differ — your actual income, expenses, rates, and timelines will produce a different answer. Use the tool iteratively: start with the defaults, then change one variable at a time to see which factor has the largest impact on your outcome.Formula
Monthly benefit = Income x benefit% | Total = benefit x months
Tips
- A 60% benefit is the norm, but the dollar cap often means high earners get much less — check the ceiling.
- A longer waiting period is the cheapest way to save premium — fund the gap with emergency savings.
- Own-occupation coverage matters most for specialists: it pays if you cannot do your specific job.
- Combine employer coverage with an individual policy to bridge caps and job changes.
Frequently asked questions
How much disability insurance do I need?
Target replacement of 60-70% of gross income — enough to cover essentials without creating a disincentive to return to work. Most group policies cap at around $10,000-15,000 per month, so high earners often add individual coverage for the gap.
What is an elimination period?
The number of days (or weeks) after disability begins before benefits start — effectively your personal deductible. Common choices are 90 or 180 days; longer elimination periods cut premiums substantially because you self-fund the early months.
Is disability insurance worth it?
For anyone whose family depends on their earned income, yes — the odds of a long-term disability before retirement are materially higher than most people estimate (roughly 1 in 4 workers). Employer coverage is a starting point; individual policies protect you across job changes.
Do I pay tax on disability benefits?
If you paid the premiums with after-tax dollars, benefits arrive tax-free. If your employer paid the premiums (typical for group plans), benefits are taxable income. The distinction changes the effective benefit by your usual tax rate.
