How This Calculator Works
Calculation methodology and assumptions
The Insurance Information Institute recommends a disability insurance policy that replaces 60-70% of your gross taxable earnings, with benefits running until at least age 65 (when Social Security disability may take over). This calculator compares your target replacement amount against your existing employer group coverage and any other disability benefits to find your monthly coverage gap — the amount of additional individual disability insurance to shop for. It also calculates how much emergency savings you'd need to bridge your policy's elimination (waiting) period: no disability benefits are paid during this period even if you're unable to work, so the III recommends having savings on hand to cover it.

What Affects Your Results
State-Specific Inputs
Each state has unique rates, fee schedules, and regulatory requirements that can affect results. This page's methodology and source card identify which inputs are sourced, modeled, or user-adjustable.
Income Level
Many calculations are income-dependent due to progressive tax brackets, phase-outs, or income-based eligibility thresholds. Higher income doesn't always mean proportionally higher costs.
Local Variations
State averages may not reflect your specific city or county. Local taxes, fees, and market conditions can vary ±20% from state averages.
Annual Changes
Tax rates, fee schedules, and regulations change. Check the recorded source-review date and verify critical numbers with the relevant agency.
Tips & Best Practices
- Always verify pre-filled values against your actual data. State averages are a good starting point but your situation may differ significantly.
- Run multiple scenarios by adjusting key inputs to see how changes affect your results. This helps with planning and decision-making.
- Compare your results across states using the related calculators linked below — especially valuable if you're considering relocating or doing business in another state.
- Bookmark this page to recalculate periodically as rates change. Check the page source card and review date before relying on a pre-filled value.
- Consult a qualified professional for major financial decisions. These calculators provide estimates based on standard formulas — a CPA or financial advisor can factor in your complete financial picture.

Our editorial standardsFrequently Asked Questions
How much disability insurance do I need?
The Insurance Information Institute recommends a policy that replaces 60-70% of your gross taxable earnings. If your employer's group long-term disability plan already covers part of that (commonly 50-60% of salary), an individual supplemental policy can fill the remaining gap.
Why doesn't disability insurance replace 100% of my income?
Insurers cap benefits below full salary intentionally — replacing 100% of income could reduce the incentive to return to work and increases the risk of fraudulent claims. The 60-70% range is designed to maintain a meaningful safety net while preserving that incentive.
What is an elimination period and why does it matter?
The elimination period (also called the waiting period) is the number of days you must be disabled before benefits start being paid — commonly 60 to 90 days. If you become disabled during this period, you receive no benefit payments at all for those days, even though you can't work, so it's important to have emergency savings that can cover your expenses until payments begin.
Is my employer's group disability insurance enough?
Often not entirely. Group long-term disability plans commonly replace around 50-60% of base salary and may exclude bonuses or commission income. If your employer pays the premiums, benefits you receive may also be taxable, further reducing your effective replacement — which is why many people buy an individual supplemental policy to close the gap.
How long should disability benefit payments last?
The Insurance Information Institute suggests choosing a policy that pays benefits until at least age 65, the point at which Social Security disability benefits may take over. Younger buyers can sometimes get lifetime benefit options at a relatively low added cost.
