How Much Disability Insurance Do I Need?
There Isn't One Percentage That's Right for Everyone.
A better starting point is to determine how much monthly income your household would actually need if your paycheck stopped, subtract the income and resources that would continue, and identify the remaining gap.
A general replacement percentage can be useful as a reference point. But it doesn't know your mortgage, your family, your savings, your employer benefits—or the financial goals your paycheck is funding.
The question isn't simply how much of your income you can insure. It's how much of your financial life you're trying to protect.
Your Paycheck Does More Than Pay the Bills
When most people think about how much income they'd need during a disability, they naturally start with the bills.
Mortgage or rent. Groceries. Utilities. Car payments. Insurance. Debt.
Those absolutely matter.
But your paycheck may also be funding the future.
Retirement contributions. Emergency savings. College funding. Investments. Other financial goals you've spent years building toward.
If you calculate only the amount necessary to keep today's bills paid, you may be calculating what you could survive on rather than what it would take to protect the financial plan you've built.
So don't begin by asking, “What's the least I could live on?” Start by asking, “What am I trying to protect?”

A disability can change your monthly expenses. Some may decrease while others could increase.
Consider changes to:
Work-related expenses
Healthcare costs
Transportation

Insurance costs
The Goal Isn't to Replace Every Dollar
Your disability income need isn't necessarily the same as your current paycheck.
The goal is to build a realistic picture of the monthly income your household would need if you couldn't work—including the financial priorities you intentionally want to continue.
Once you have that number, you can begin subtracting the income and resources that would still be available.
What's left is the income protection gap we're trying to identify.
Income Protection Gap: Four Steps to Find Your Number
1. Determine Your Monthly Need
3. Decide What You'll Self-Insure
2. Identify What Would Continue
Estimate what your household would realistically need each month if you couldn't work—including the financial priorities you intentionally want to continue.
2. Identify What Would Continue
3. Decide What You'll Self-Insure
2. Identify What Would Continue
Account for income that would still be available, such as:
Spouse or partner income
Employer disability benefits
Existing individual disability insurance
Other reliable income
3. Decide What You'll Self-Insure
3. Decide What You'll Self-Insure
3. Decide What You'll Self-Insure
Consider resources you've intentionally decided to use during a disability, such as emergency savings or a dedicated reserve.
The question isn't simply how much money you have. It's how much you're actually willing to use for this risk.
4. Find Your Gap
3. Decide What You'll Self-Insure
3. Decide What You'll Self-Insure
Now put the pieces together:
- Start with: Your Monthly Need
- Subtract: Continuing Income
- Subtract: Resources You Intentionally Self-Insure
- Equals: Your Income Protection Gap
Your Gap Is a Planning Number
- Start with your Monthly Need
- Subtract: Continuing Income
- Subtract: Resources You Intentionally Self-Insure
- Equals: Your Income Protection Gap
Your income protection gap isn't automatically the amount of disability insurance you should buy—or even the amount an insurance company will make available.
It's a planning number: an estimate of the monthly income your household could be missing if your paycheck stopped after accounting for the resources that would still be there.
That gap—not an arbitrary percentage—is the number worth understanding.
Let's Put Some Numbers Behind It
Meet Rachel and Andy
Rachel earns $120,000 per year and Andy earns $70,000, giving them a combined household income of $190,000.
Like most households, their income does more than pay today's bills. It also funds retirement savings and other financial priorities they want to continue.
If Rachel became unable to work because of a disability, the question wouldn't simply be, “What percentage of her income should we replace?”
It would be:
“How much income would their household actually need, and how much would still be available?”

Food, utilities & household: $1,600

Everyday needs: $5,000
Financial obligations: $2,000
Future & lifestyle: $1,900
Total: $8,900/month
Now Let's Find Their Income Protection Gap
But $1,900 Isn't the Whole Story
Rachel and Andy have determined that they would want approximately $8,900 per month to keep their household running and continue the financial priorities they've chosen to protect.
If Rachel became disabled, not all of their household income would disappear. Andy would continue bringing approximately $4,000 per month into the household, and Rachel's employer disability plan would provide a $3,000 monthly gross benefit.
So let's apply the calculation:
Start with: $8,900 Monthly Need
Subtract: $4,000 Continuing Household Income
Subtract: $3,000 Gross Employer Disability Benefit
Equals: $1,900 Preliminary Income Protection Gap
But remember, Rachel's employer pays the premium for her disability coverage, so we're assuming her LTD benefits would generally be subject to federal income tax.
That means the full $3,000 gross monthly benefit wouldn't necessarily be available to support their household after federal income taxes.
Their actual income protection gap would therefore be greater than $1,900 per month.
And that's an important part of calculating your own need: don't simply subtract the benefit shown in your employer plan without understanding what that benefit may actually provide.

What If They Just Stop Saving?
A Smaller Gap Can Come With a Cost
Remember, Rachel and Andy included $1,200 per month for retirement and long-term savings when they calculated their $8,900 monthly need.
They could simply decide to stop those contributions if Rachel became disabled.
Doing that would reduce their monthly need from $8,900 to $7,700 and reduce their preliminary income protection gap from $1,900 to $700 per month—before considering the taxes on Rachel's employer disability benefit.
On paper, their gap suddenly looks much smaller.
But they didn't eliminate a financial need. They decided to stop funding part of their financial future.
If those contributions stopped for five years, Rachel and Andy would miss $72,000 in contributions alone, before considering any potential investment growth.
That doesn't mean continuing every savings goal during a disability is necessarily the right decision. They may intentionally decide that some goals would pause.
The important thing is to make that decision intentionally—not because those goals were simply left out of the calculation.
What About the 60% Rule?
A Useful Starting Point—Not a Needs Analysis
You may hear that disability insurance should replace around 60% of your income. Percentage guidelines like this can be useful as a quick reference, and disability insurance is generally designed to replace only a portion of your income.
But a percentage doesn't know your household.
Two people earning the same income can have very different mortgages, family responsibilities, employer benefits, savings, debt and long-term financial goals.
Rachel and Andy are a good example. Their income protection need wasn't determined by simply multiplying Rachel's salary by 60%. It came from looking at what they wanted to protect and what resources would still be available if her paycheck stopped.
Use the percentage as a reference point—not as a substitute for understanding your actual need.
Already have disability insurance through work? Make sure you understand what your coverage actually provides.
How Much You Need Isn't Always How Much You Can Buy
Two Different Questions
Once you've identified your income protection gap, there's another question to consider: How much disability insurance is actually available to you?
Individual disability insurance companies generally consider your income and existing disability coverage when determining how much monthly benefit may be available.
If you're self-employed, determining that income can work a little differently. Learn what to consider when you're building your own disability insurance safety net.
That means your needs analysis could identify a $5,000 monthly gap, while the amount of additional coverage available to you could be different.
The reverse matters too. Just because you may qualify to purchase a certain amount of coverage doesn't automatically mean that's the amount you need.
Eligibility isn't a needs analysis.
So, How Much Disability Insurance Do I Need?
Start With Your Gap, Not a Percentage
Start with the amount of monthly income your household would realistically need if you couldn't work.
Subtract the income that would continue. Account for disability benefits you already have. Decide how much of the risk you're intentionally willing to self-insure.
What's left is your income protection gap.
Then compare that planning need with the amount of individual disability coverage that may actually be available to you.
You may discover you need more protection than you currently have. You may discover your existing coverage and resources already do the job. Or you may decide you're comfortable protecting only part of the gap.
Once you know how much you may want to protect, the next question is what that coverage might cost.
The goal isn't to buy the most disability insurance possible. It's to make an informed decision about how much of your paycheck—and your financial plan—you want to protect.

Frequently Asked Questions
Not necessarily. A percentage can be a useful starting point, but it doesn't account for your actual household expenses, other income, existing disability benefits, taxes, savings goals or the amount you're comfortable self-insuring.
A better approach is to calculate the monthly income your household would need, subtract the resources that would still be available, and identify the remaining income protection gap.
That gap gives you a more personalized starting point for deciding how much disability insurance may be worth considering.
Yes. Employer disability coverage is an important part of the calculation, but don't automatically subtract the percentage shown in your benefits booklet.
Look at what income is actually covered, the plan's monthly benefit maximum, whether benefits may be taxable, and any other limitations that could affect what you receive.
The amount that would realistically be available to your household is what matters when calculating your income protection gap.
Savings can absolutely be part of your income protection plan. The important question is how much of those savings you're actually willing to use if you couldn't work.
You might choose to use savings to cover a waiting period or intentionally self-insure part of your monthly need. But using money earmarked for retirement, college or other long-term goals can create a different financial tradeoff.
Count the resources you've intentionally decided to use—not simply everything you have available.
Not always. Insurance companies generally limit the amount of disability coverage available based on factors such as your income and existing disability benefits.
That's why your income protection gap is a planning number, not automatically the amount of insurance you can—or should—buy.
The goal is to understand your gap first, then determine how much of it can and should be addressed through insurance and how much you're comfortable handling with your other resources.
It's worth revisiting whenever your financial life changes significantly—such as a change in income, a new home, marriage, children, new debt or a change in your employer benefits.
Even without a major life event, periodically reviewing the numbers can help make sure the assumptions you made several years ago still reflect your household today.
Your income protection need isn't necessarily a number you calculate once and forget.
You Don't Have to Figure It Out Alone
Know Your Number. Then Decide What to Do With It.
Figuring out how much disability insurance you need isn't about finding a perfect percentage or buying as much coverage as possible.
It's about understanding what your household would need, what resources would still be available, and where a gap may exist.
If you've worked through the numbers and still have questions—or you'd like help reviewing what you already have—I'm happy to help.
No pressure. No obligation. Just a conversation about what you're trying to protect and whether it makes sense to do anything about it.
