How Much Life Insurance Do Military Families Need? (SGLI vs Civilian)

Most military families don’t worry about life insurance until something changes. A new baby. A PCS. A mortgage. Or a buddy’s close call. Then the question hits hard: How much life insurance do we actually need? A good military life insurance calculator can help, but only if you understand what it’s measuring. Because “max out SGLI” is not the same as “my family is covered.”

Let’s break down military life insurance needs in plain English, with real numbers. We’ll compare SGLI vs term life, talk about spouse coverage (FSGLI), and show how VGLI works after you leave the service.

Background: What SGLI, FSGLI, and VGLI really are (and what they aren’t)

SGLI (Servicemembers’ Group Life Insurance) is the basic life insurance for most active duty members and many Guard/Reserve members. It’s group insurance, meaning you get coverage based on your status, not your health.

Key points:

• Coverage limit: Up to $500,000 (in $50,000 steps).
• Who it covers: You (the service member).
• How it pays: A tax-free death benefit to your chosen beneficiaries.
• Where to verify details: VA SGLI overview

FSGLI (Family SGLI) covers spouses and dependent children.

• Spouse coverage: Up to $100,000, but not more than the member’s SGLI amount.
• Child coverage: Typically $10,000 per child at no cost.
• Source: VA FSGLI overview

VGLI (Veterans’ Group Life Insurance) is what you can convert to after separating.

• You generally must apply within set time windows after leaving service.
• It’s usually more expensive as you age, because premiums go up in age bands.
• Source: VA VGLI overview

Here’s the big “gotcha”: SGLI is great, but it’s a cap, not a plan. Your real need depends on your income, debt, kids, and spouse’s ability to work.

If you’re also a federal employee (or becoming one), you may also have FEGLI (Federal Employees’ Group Life Insurance). FEGLI can help, but it’s not always cheap for long-term coverage. Learn more at OPM.gov. (FedInfo also covers federal benefits and pay basics.)

Use a SGLI calculator mindset: start with your “income replacement” number

A simple SGLI calculator (or any military life insurance calculator) usually starts with one main idea:

Step 1: Replace income for a set number of years

A common rule of thumb is 10–15 years of income. But let’s make it real.

If your take-home support to the family is about $60,000 per year and you want 12 years of support:

• $60,000 × 12 = $720,000

That already exceeds the $500,000 SGLI cap.

Step 2: Add big one-time costs

Common add-ons:

• Mortgage payoff (or enough to reduce payments)
• Child care (if your spouse will need it to keep working)
• College goal (optional, but many families want it)
• Debt (car loans, credit cards, personal loans)
• Final expenses (funeral costs can run $10,000–$20,000)

Example add-ons:

• Mortgage balance: $280,000
• Car loan: $18,000
• Credit cards: $6,000
• Final expenses: $15,000

Total add-ons = $280,000 + $18,000 + $6,000 + $15,000 = $319,000

Step 3: Subtract what your family already has

This is where many people skip the math.

Subtract:

• Savings (emergency fund)
• Existing civilian term life
• Expected survivor benefits (if applicable)

For military families, survivor benefits can include things like Dependency and Indemnity Compensation (DIC) and other programs, depending on the situation. These are real but can be complex. Start at VA.gov and Military OneSource for help.

If you have:

• Savings: $30,000
• Spouse has term life: $100,000 Total existing = $130,000

Put it together (simple needs formula)

• Income replacement: $720,000
• One-time costs: $319,000
• Minus existing: $130,000

Total need = $909,000

That’s your target. SGLI at $500,000 covers about half. The gap is $409,000. That gap is where civilian term life often fits.

SGLI vs term life: what each one is best at (with real tradeoffs)

SGLI is often the best deal when you’re young and healthy and you want coverage now with no medical exam. But term life (civilian) can be cheaper for the long run, and it can go higher than $500,000.

When SGLI shines

• You want coverage today, no questions asked.
• You have a medical issue that could raise civilian rates.
• You deploy or do a risky job and don’t want exclusions.

SGLI is also simple. You can set it and move on.

When civilian term life shines

• You need more than $500,000.
• You want to lock a price for 20 or 30 years.
• You want coverage that stays with you after you leave service, without switching to VGLI.

A common smart move is:

• Keep SGLI at $500,000
• Add $250,000 to $1,000,000 of level term life (20–30 years), based on your gap

Watch-outs with VGLI

VGLI can be a lifesaver if you’re not healthy enough for civilian insurance. But for many people, it becomes pricey later.

Here’s the practical takeaway:

• If you’re healthy, consider buying civilian term before you separate.
• If you’re not healthy, VGLI may be your best option even if it costs more.

You can confirm VGLI rules and timelines on VA.gov.

Practical examples: military life insurance needs for 3 real families (with math)

Below are three “kitchen table” examples. These aren’t perfect financial plans. But they show how a military life insurance calculator should think.

Example 1: E-5 with 6 years, married, 2 kids, one income

Situation

• Service member: E-5 over 6
• Spouse stays home
• Kids: ages 3 and 1
• Mortgage balance: $310,000
• Savings: $15,000
• Goal: replace support for 15 years
• Estimated family support needed: $55,000/year

Step-by-step

1. Income replacement: $55,000 × 15 = $825,000
2. One-time costs:
   • Mortgage: $310,000
   • Final expenses: $15,000
   • Debt (cards + car): $25,000
     Total = $350,000
3. Subtract savings: $15,000

Total need: $825,000 + $350,000 − $15,000 = $1,160,000

Coverage plan idea

• SGLI: $500,000
• Gap: $660,000
• Add civilian term: $750,000 (20–30 year) to give a buffer

Why buffer? Inflation and child care costs tend to rise. And life happens.

Example 2: O-3, dual-income, no kids (yet), big student loans

Situation

• Both spouses work
• No kids today, but planning in 2 years
• Student loans: $120,000
• Mortgage: $0 (renting)
• Savings: $60,000
• Goal: cover debts + give spouse time to grieve and reset (say 5 years)
• Needed support: $40,000/year (because spouse can cover basics)

Math

1. Income replacement: $40,000 × 5 = $200,000
2. One-time costs:
   • Student loans: $120,000 (note: some federal loans can be discharged on death, but not all private loans—check your loan type at StudentAid.gov)
   • Final expenses: $15,000
     Total = $135,000
3. Subtract savings: $60,000

Total need: $200,000 + $135,000 − $60,000 = $275,000

Coverage plan idea

• SGLI at $300,000 could be enough right now
• Or keep SGLI at $500,000 and plan to adjust when kids arrive

This is a good example of not overbuying if your spouse has strong income and you have no mortgage.

Example 3: Guard/Reserve member + federal employee (FERS), 3 kids, spouse works part-time

Situation

• Member is a GS employee (FERS) and also in the Guard
• 3 kids: ages 10, 7, 4
• Mortgage: $260,000
• Savings: $40,000
• Spouse income is part-time; needs child care to go full-time
• Child care estimate: $1,200/month for 5 years = $1,200 × 60 = $72,000
• Goal: replace $50,000/year for 12 years

Math

1. Income replacement: $50,000 × 12 = $600,000
2. One-time costs:
   • Mortgage: $260,000
   • Child care bridge: $72,000
   • Final expenses: $15,000
     Total = $347,000
3. Subtract savings: $40,000

Total need: $600,000 + $347,000 − $40,000 = $907,000

Coverage plan idea

• SGLI: $500,000
• Consider civilian term: $500,000 (20 years) to cover the gap
• If also eligible for FEGLI as a federal employee, compare costs at OPM.gov. FEGLI can be useful, but it’s not always the cheapest long-term.

Also, don’t forget health coverage planning. TRICARE rules are at TRICARE.mil, and federal health options are at OPM FEHB. Health costs can change your “years of income replacement” choice.

Common mistakes and misconceptions (that cost families real money)

1. “If I die, the military will take care of my family.”
   Some benefits exist, but they may not replace your full income for years. Plan for your real bills.

2. Only insuring the service member, not the spouse.
   If your spouse dies, you may need paid child care fast. FSGLI spouse coverage caps at $100,000, which may not be enough.

3. Picking a number without doing the math.
   $500,000 sounds huge until you run the mortgage + income math.

4. Forgetting to update beneficiaries after big life events.
   Marriage, divorce, new baby, or a death in the family should trigger a review.

5. Assuming VGLI will be “about the same price” as SGLI.
   VGLI can get expensive as you age. Use it wisely, but don’t assume it’s cheap forever.

Step-by-step: how to run your own military life insurance calculator (in 20 minutes)

You can do this with a notes app and a calculator.

Step 1: Choose your “support years”

Pick a number:

• 5 years if spouse has strong income and no kids
• 10–15 years if you have kids or a one-income home
• Until youngest is 18 if you want a simple kid-based target

Write it down.

Step 2: Estimate annual support needed

Start with your monthly budget. Use a rough number if you must.

Example:

• Housing + food + utilities + cars + insurance = $4,500/month
• That’s $4,500 × 12 = $54,000/year

Step 3: Add one-time costs

List your big items:

• Mortgage balance
• Other debts
• Final expenses ($10k–$20k is a common planning range)
• Child care bridge (if needed)

Step 4: Subtract what you already have

List:

• Savings
• Existing life insurance (yours and spouse’s)
• Any other assets you want counted

Be honest. Don’t count your car at “for sale value” unless you really would sell it.

Step 5: Compare to SGLI and FSGLI limits

• SGLI max: $500,000
• FSGLI spouse max: $100,000 If your need is higher, you’re looking at supplemental term life.

Step 6: Build a simple coverage plan

Many families land on one of these:

• Plan A: SGLI $500k only (works for lower-need or dual-income, low-debt homes)
• Plan B: SGLI $500k + $250k–$1M term life (most common for kids + mortgage)
• Plan C: SGLI $500k + larger term + spouse term (best when spouse income/child care risk is big)

If you’re separating soon, add a note: “Compare term vs VGLI now.” Don’t wait until after you’re out.

(And if you’re dealing with an injury or illness, also review disability and workers’ comp programs. Federal resources start at DOL OWCP for federal workers and VA.gov for VA benefits.)

Key takeaways / Bottom line

SGLI is a strong baseline, but it’s not a custom plan. A quick SGLI calculator approach—income replacement + debts + child care, minus savings—usually shows why many families need more than $500,000, especially with kids and a mortgage. FSGLI helps, but spouse coverage tops out at $100,000, so don’t ignore spouse term insurance. If you’re healthy, locking in civilian term early can beat VGLI long-term. If you’re not healthy, VGLI can still be a critical backup.
