BRS vs High-3: Which Military Retirement Plan Is Better?

If you joined the military after January 1, 2018, you're automatically in the Blended Retirement System. If you were already serving before that date, you had a choice: stay with High-3 or switch to BRS. Either way, understanding how these plans work could mean hundreds of thousands of dollars over your lifetime. This isn't just pension math. It's about knowing what you actually own and what's yours if you walk away.

High-3: The Legacy Plan

The High-3 pension is the one most of us grew up hearing about. Serve 20 years, and you get 50% of your highest 36 months of base pay. For life. Every year past 20 adds another 2.5%. An E-7 with 20 years might pull in about $2,800 per month forever. Make it to 25 years? Now you're at about $3,500 per month. That's real, predictable money hitting your account every single month for the rest of your life.

But here's the part nobody talks about at career day. Only about 17% of service members actually make it to 20 years. The other 83% separate before that. And if you leave at 19 years and 11 months under High-3? You get absolutely nothing from the pension. Zero. Not a dollar. You spent nearly two decades serving your country, and there's no retirement benefit waiting for you. That's the hard truth about the legacy system.

BRS: Three Parts Working Together

The Blended Retirement System changes things because it doesn't put all your eggs in the 20-year basket. It has three pieces.

First, there's still a pension, but it's smaller. At 20 years you get 40% of your base pay instead of 50%. Each year beyond 20 still adds 2.5%. So that same E-7 would get roughly $2,240 per month instead of $2,800. That's $560 less every month, and over a 30-year retirement, that gap adds up.

Second, and this is the big one: TSP matching. The military matches up to 5% of your base pay into your Thrift Savings Plan. And here's the crucial part—this money is yours regardless of how long you serve. Separate after 4 years? You take that TSP balance with you. It's vested. You own it. Under High-3, you'd walk away from those 4 years with nothing for retirement. Under BRS, you've been building wealth the entire time.

Third is continuation pay. Around your 12-year mark, you can get a one-time bonus between 2.5 and 13 times your monthly base pay, depending on your branch and MOS. It's designed to keep you around for the back half of your career. The amount varies, but it's a meaningful chunk of cash right when you're deciding whether to push for 20.

The Numbers Side by Side

Let's get specific. An E-7 with 20 years under High-3 receives about $2,800 per month in pension. Under BRS, that drops to about $2,240. That's a $560 monthly difference, or $6,720 per year. Over 30 years of retirement, the pension gap alone is over $200,000.

But BRS gives you TSP matching from day one. If you contribute 5% and the military matches 5%, that's 10% of your base pay going into your TSP every month. Assuming a 7% annual return over 20 years, that compounds into a TSP balance somewhere between $200,000 and $300,000. And that's just from the match—your own contributions push that number higher.

So if you do the full 20 and factor in both the pension and the TSP, the total retirement value is actually pretty close. The difference is that with High-3, all your money is in a government pension. With BRS, you've got a pension plus a fat investment account you can manage yourself.

The 83% Who Don't Stay 20 Years

This is the argument that tips the scale for most people. The majority of service members don't make it to 20 years. They serve 4 years, or 8, or 12, and then move on. Under High-3, every single one of them walks away with zero retirement benefit. All those years of service, and nothing to show for it on the retirement front.

BRS changes that completely. An E-5 who serves 8 years under BRS has been getting TSP matching the whole time. They might walk away with $50,000 to $80,000 in their TSP. That's money they can roll into a civilian 401(k) or just let grow until they're 59. Under High-3, that same E-5 would leave with nothing.

For most people—the 83% who won't hit 20—BRS is hands-down the better deal. It's not even close.

The Lump Sum Trap

BRS offers a lump sum option at retirement: take 25% or 50% of your pension up front in exchange for reduced monthly payments until age 67. It sounds tempting, especially when you're looking at a six-figure check. But the math rarely works in your favor. You're trading decades of guaranteed monthly income for cash today, and unless you have a very specific plan for that money—a business opportunity, a medical situation, something concrete—the monthly payments will serve you better over the long haul.

So Which One's Better?

If you're certain you're doing 20+ years and you were grandfathered into High-3, staying put is probably the right call. The bigger pension is hard to beat when you know you're going the distance.

But if there's any chance you might leave before 20—and statistically, there's a very good chance—BRS gives you something to take with you. And even if you do stay 20 years, the TSP matching narrows the gap more than most people think. Don't forget that your retirement income picture also includes VA disability compensation—retirees with a 50%+ combined rating can receive both their pension and tax-free VA disability pay through concurrent receipt.

And if you're just starting out, keep in mind that your retirement outcome starts long before you hit 20 years. It starts with preparing for the ASVAB and choosing a job you actually want to do for two decades. People who enjoy their MOS are far more likely to reenlist and reach that 20-year mark. The ones who picked a job they hated because they didn't study for the ASVAB? They're disproportionately in that 83% who leave early.

The best way to know for sure is to run the numbers with your own rank, years of service, and assumptions about investment returns. That's what calculators are for.
