Short-Term vs Long-Term Disability Insurance: How They Fit Together

CoverageGap Team · Published October 28, 2026 · 9 min read

Short-term disability pays you for a few months. Long-term disability pays you for years. That's the textbook split, and it's accurate, but it hides the part that actually costs people money: the two plans are built to hand off to each other, and if their dates don't line up there can be weeks or months in the middle where nothing is paid at all.

This guide covers what each type does, how they compare, and how to check whether yours connect. If you're still working out how much total coverage you need, start with our guide on how much disability insurance you need and come back.

What short-term disability covers

Short-term disability (STD) replaces part of your paycheck while you recover from something temporary: surgery, a serious injury, a difficult pregnancy, a hospital stay. Typical terms, according to Thrivent's overview, are:

• Waiting period: 7 to 30 days, with 14 days common.
• Benefit: somewhere between 40% and 100% of base income, usually near 60%.
• Duration: 13 to 26 weeks in most plans.

Most STD comes through an employer. Only a handful of places require it by law, which we'll get to below.

What long-term disability covers

Long-term disability (LTD) is for the injuries and illnesses that keep you out of work for a long stretch: cancer, a serious back injury, a stroke, severe mental health conditions. It starts later and lasts much longer.

• Waiting period (elimination period): as short as 30 days, but 90 or 180 days is what most group plans use.
• Benefit: roughly 40% to 66⅔% of income on a group plan, and up to about 80% on an individual policy.
• Duration: from about two years up to retirement age, and on some individual policies for life. The Maine Bureau of Insurance notes that long-term benefit periods can run from five years to the rest of your life, so the maximum benefit period is worth checking before you buy.

The two types side by side

Ranges here come from Thrivent and Experian, and the two don't always agree to the dollar, which is a reminder that your plan document is the only source that counts.

Where the gap hides

Here is the same timeline for three setups, drawn to the same scale over 30 weeks from the day you stop working.

Read the first two rows together and they connect cleanly: short-term pays until about week 13, and a long-term plan with a 90-day wait starts right as it ends. Now read the first and third rows. Pair that same short-term plan with a long-term plan that has a 180-day wait and you get roughly 13 weeks with no benefit from either one.

Social Security doesn't fix this. SSDI has a five-month waiting period, and the average payment is about $1,630 a month, so even if you're approved it replaces only a fraction of a typical paycheck.

A worked example

That $13,800 is the same figure the calculator produces for a 90-day cushion at this salary. If you want to see how it looks for your own numbers, here is the result panel for this exact example:

Which states require short-term disability?

Six jurisdictions run temporary disability programs: California, Hawaii, New Jersey, New York, Rhode Island, and Puerto Rico, according to the Social Security Administration's program summary. Rhode Island runs an exclusive state fund, while New York and Hawaii require employers to provide their own coverage. That summary is a few years old, so confirm current rules with your state labor department. Outside these places, short-term coverage is a benefit your employer decides to offer, and no state requires long-term.

How to check whether yours line up

1. Find the short-term end date. Look for the maximum benefit period in weeks, not just the percentage.
2. Find the long-term waiting period. It is labelled "elimination period" in most plan documents.
3. Compare them. If the long-term wait is longer than the short-term benefit, that difference is your gap.
4. Check whether short-term counts toward the wait. Some plans count the days you receive STD as part of the elimination period, which closes the gap automatically.
5. Price the gap. Multiply the months of gap by your monthly bills and compare that to what you have in savings.

Before you settle on a plan, also check how it defines disability after the first couple of years (own occupation vs any occupation) and whether the benefit is taxed (is disability insurance taxable?).

Who should buy which

If your employer offers both and the dates connect, you're mostly set on structure, and the open question is whether the amounts are enough. If you only have short-term, the exposure is the long, expensive scenario, so long-term is the one to add. If you have neither, because you're self-employed or your employer offers nothing, start with an individual long-term policy and choose a waiting period you can actually fund from savings. A longer wait lowers the premium, but only if you can cover the extra weeks yourself.

One more check before buying: preexisting conditions. According to the Maine Bureau of Insurance, an insurer may permanently exclude a condition you already have, or decline to sell you the policy, so disclose accurately on the application.
