The Short Answer
Most disability policies replace roughly 60% of your gross monthly income. This tool takes that standard benefit ratio, then estimates a monthly premium using the typical 1% to 3% of annual income range, adjusted for your occupation risk class and elimination period. A longer elimination period, the waiting time before benefits start, lowers the premium because you self-insure through a larger chunk of any disability.
Short-Term vs Long-Term: Which Do You Need
Short-term disability covers gaps lasting days to six months. It typically starts paying after a 7- to 14-day elimination period and is often bundled into group benefits at work. The premiums are lower because the coverage window is narrow.
Long-term disability is the policy that matters most for financial planning. It picks up where short-term coverage ends and can run for 2 years, 5 years, 10 years, or to age 65. According to the Social Security Administration, about one in four 20-year-olds will experience a disability lasting longer than 90 days before they reach 67. That number is why long-term coverage deserves serious attention.
What the Social Security Disability Program Does Not Cover
Social Security Disability Insurance (SSDI) exists, but average approval takes well over a year, the average monthly benefit runs around $1,400 as of recent SSA data, and two-thirds of initial applications are denied. A private or group long-term policy provides faster and often larger coverage while your SSDI claim processes, if you file one at all. Outside of occupation class, carriers also weigh your age, health history, and whether the policy is own-occupation or any-occupation, with own-occupation costing more but protecting more for specialized professionals.
