Should I Stay in the Military to 20 Years?

The financial case for and against grinding to retirement

Mil-Multiplier › Blog › Should I Stay in the Military to 20 Years?

This is the single biggest financial decision most service members face. The military retirement pension — 50% of your base pay for life starting the day you retire — is worth $1 million to $2 million in present value depending on your rank. Walking away at 15 or 18 years means leaving that entire amount on the table. But staying in a job that's destroying your mental health or family life has real costs too.

Let's break down the actual math so you can make this decision with data, not emotion.

What the Pension Is Actually Worth

Under the High-3 system, a 20-year retiree receives 50% of their average highest 36 months of base pay. For an E-7 retiring in 2026 with 20 years, that's approximately $3,123/month or $37,476/year — for life, with annual COLA increases. If you retire at age 40 and live to 80, that's $1.5 million in gross payments, not counting COLA growth.

Under BRS (Blended Retirement System), the multiplier drops to 40% at 20 years, giving roughly $2,498/month. However, BRS includes TSP matching throughout your career, which can partially or fully close the gap if you've been contributing consistently.

E-7 Retirement Value: The Numbers

High-3 at 20 years: ~$3,123/month × 12 = $37,476/year

Lifetime value (age 40-80): ~$1,499,000 before COLA

With 2.5% annual COLA: ~$2,400,000+ lifetime

BRS at 20 years: ~$2,498/month + TSP matching value

The Opportunity Cost of Staying

The pension math looks compelling in isolation. But there's a hidden cost: the years you spend staying in are years you're not building a civilian career. If you're at 16 years and miserable, you're looking at 4 more years of suppressed career growth, potential deployments, PCS moves that disrupt your spouse's career, and the mental health toll of serving in a role you've outgrown.

A 36-year-old E-7 who separates and enters a $85,000 civilian role will earn $340,000 over those 4 years. The same E-7 staying in earns roughly $300,000 in military compensation over the same period. The civilian path earns more now but misses the pension. The military path earns less now but unlocks $37K+/year for life.

VA Disability Changes the Equation

Here's what most "stay to 20" calculators ignore: VA disability compensation. If you separate at 16 years with a 70% VA rating, you receive approximately $1,716/month ($20,592/year) tax-free for life. That's not a pension, but it's guaranteed income that significantly reduces the financial penalty of separating early.

The real comparison isn't "pension vs nothing" — it's "pension vs VA disability + civilian salary." An E-7 separating at 16 years with a 70% rating and an $85K civilian job has a combined income of $105,592. The same E-7 retiring at 20 with the pension and an $85K civilian job has $122,476 — only $17K more, and they waited 4 years to get there.

Use the VA Rating Estimator to estimate your potential rating, then run both scenarios in the Compensation Calculator.

When Staying Makes Obvious Sense

The math strongly favors staying if you're at 17+ years (the finish line is close), you're in a tolerable assignment, your spouse's career isn't being damaged by PCS moves, and you don't have a specific civilian opportunity waiting. The pension's lifetime value is simply too large to walk away from with 3 years left.

When Leaving Makes Sense

The math favors leaving if you're at 12-15 years (still 5-8 years away), you have a strong VA disability claim, you have civilian skills that command $90K+ immediately, or the mental health cost of staying is affecting your family. No pension is worth a destroyed marriage or clinical depression.

The Bottom Line

Run your specific numbers. Don't let anyone tell you the answer is obvious in either direction — it depends on your rank, years of service, VA disability potential, civilian earning power, and personal circumstances. The tools on this site exist precisely for this decision. Start with the Compensation Calculator to understand your true military value, factor in your VA claim, and compare against realistic civilian salary targets.

How I Think About This Decision Personally

I'm at 10 years right now. Made E-7 at 8, which means I have a decade of service left if I'm going to 20. I've had this exact conversation with myself — usually at 2 AM after a 16-hour day wondering why I'm still doing this when I could be making $120K writing code from home.

Here's what keeps coming back to math. At 20 years, my High-3 pension is roughly $3,200-3,500/month for life, with COLA adjustments every year. That's $40K/year guaranteed before I earn a single dollar in a civilian job. Add VA disability (which I will absolutely file for — see the article on filing before separation) and I'm looking at $55-65K/year in passive income at age 40. That changes every subsequent career decision because I'll never need to take a job I hate just to pay the mortgage.

The counterargument is opportunity cost. If I got out at 10 years and landed a $110K civilian job immediately, I'd earn $1.1M over the next 10 years. Staying to 20 means 10 more years of E-7/E-8/E-9 pay instead. The pension starts paying at 40 and takes 12-15 years to break even against the civilian earnings I gave up. By 55, the pension pulls ahead because it's guaranteed income I never have to work for. By 65, it's not even close — the pension wins by hundreds of thousands.

But math isn't the only factor. Ten more years means ten more PCS moves, ten more years of being told where to live, ten more years of field problems and 4 AM formations and time away from family. For some people that's a dealbreaker at year 8. For me, the tradeoff still makes sense because I'm in a position (SFAB) where the work is meaningful and the deployment tempo is manageable. If I were stuck in a toxic battalion with a terrible command team, the math might not be enough.

The right answer depends on your specific situation — your rank, your MOS, your family, your civilian marketability, and honestly, whether you still wake up wanting to be here. The calculator gives you the financial answer. The personal answer is yours.
