Long-term disability (LTD) insurance replaces a portion of your income when a serious illness or injury prevents you from working for months or years. This calculator estimates your monthly LTD benefit, total annual payout, and income replacement ratio based on your gross income, elimination period, benefit period, and coverage percentage — helping you evaluate whether existing coverage is sufficient or identify gaps.

How to Calculate Your Long-Term Disability Benefit
Long-term disability insurance is one of the most overlooked yet critical financial protections. The Social Security Administration estimates over 1 in 4 workers will experience a disabling condition before reaching retirement age. This LTD benefit calculator helps you understand exactly what you'd receive and whether it's enough.
Step 1: Enter Your Gross Monthly Income
LTD benefits are calculated as a percentage of your pre-disability gross (before-tax) income. Enter your monthly gross income — for example, if you earn $72,000 annually, enter $6,000. Include only base salary; bonuses and commissions may or may not be covered depending on your policy.
Step 2: Choose Your Coverage Percentage
Most LTD policies replace 60-70% of gross income. A 60% replacement on a $6,000/month income yields $3,600/month in benefits. Some high-income policies cap the maximum monthly benefit at $5,000-$15,000 regardless of income. The 60% standard is designed so that when combined with lower post-disability expenses, you maintain a similar net lifestyle.
Step 3: Select the Elimination Period
The elimination period is the waiting period between disability onset and first benefit payment. A 90-day elimination period is the most cost-effective for most workers — it significantly lowers premiums while requiring only 3 months of emergency savings to bridge. If you have solid savings (6+ months), a 180-day period saves even more on premiums.
Step 4: Choose the Benefit Period
This is how long benefits continue if you remain disabled. A "to age 65" benefit period is the gold standard — it protects you until Social Security kicks in. Two-year or five-year benefit periods cost significantly less but leave you unprotected for long-term disabilities like spinal injuries, cancer treatment, or mental health conditions that last years.
Understanding Your Results
The calculator shows your monthly benefit (gross income × coverage %), annual benefit, income replacement ratio, and maximum total benefit over the full benefit period. Pay special attention to the elimination period gap — this is the amount you need in savings to cover expenses while waiting for benefits to start.
Frequently Asked Questions

What is the typical LTD benefit percentage?
Most long-term disability policies replace 60-70% of your pre-disability gross income. Some policies cover up to 80%, though higher percentages mean higher premiums. The benefit is often capped at a maximum monthly dollar amount regardless of income level.
What is an elimination period for LTD?
The elimination period (also called waiting period) is the time you must be disabled before benefits begin. Common options are 30, 60, 90, or 180 days. Longer elimination periods lower your premium significantly. Most financial advisors recommend 90 days if you have 3+ months of emergency savings.
What does 'benefit period to age 65' mean?
A benefit period to age 65 means your LTD benefits continue until you reach retirement age (or recover), providing the longest protection. Shorter benefit periods (2 or 5 years) cost less but leave you exposed if disability lasts longer. For permanent disabilities, a longer benefit period is essential.
Are long-term disability benefits taxable?
If your employer pays the premiums, LTD benefits are generally taxable as ordinary income. If you pay premiums with after-tax dollars, benefits are typically tax-free. This calculator shows gross benefit amounts — consult a tax advisor for net-after-tax estimates.
How much does long-term disability insurance cost?
Individual LTD insurance typically costs 1-3% of your annual gross income. Factors include occupation risk, age, benefit period, elimination period, and coverage percentage. Employer group LTD is often subsidized and significantly cheaper than individual policies.
