Military Retirement Calculator: High-3, BRS and Reserve Points

Updated August 21, 2026. Quick answer: military retired pay is your high-3 average basic pay — the services also call it High-36 — multiplied by a percentage: 2.5% per year of service under the legacy system, 2.0% under the Blended Retirement System. Guard and Reserve service converts retirement points ÷ 360 into years first, and only a year with at least 50 points counts toward the twenty you need. This reproduces the regulation’s own published examples, and the table below gives the high-3 by rank if you do not know yours.

Your number

What it comes to by rank, if you do not know your high-3

The calculator above needs one number most people cannot produce from memory: the high-3 average itself. This is what it works out to for a member retiring at exactly twenty years, computed from the basic-pay rates in force for 2026.

Read these as the shape of the answer, not as your answer. Three things about them are worth stating plainly rather than burying. They hold the 2026 pay table constant across all thirty-six months, so they describe someone whose last three years were all paid at today’s rates; a real high-3 averages three successive years’ tables and comes out lower in nominal terms than the final year alone. They assume the promotion is already behind you — twelve months in the over-16 column and twenty-four in the over-18 column, which is how those thirty-six months fall for a twenty-year retirement. And they are basic pay only: no BAH, no BAS, no special or incentive pay, because none of those are in the high-3.

Away from exactly twenty years the arithmetic is the same and the multiplier simply moves: each additional year adds 2.5 points of multiplier under the legacy system and 2.0 under BRS, so a legacy E-7 at 24 years is at 60%, not 50%. Put your own high-3 into the calculator above and it will do it.

It matches the regulation’s own examples

The Financial Management Regulation publishes worked examples, and a calculator that cannot reproduce them is not worth using. This one does, on both:

High-3 is not your final pay

The base is defined by statute as the average of the 36 months — which is why the services and the pay clerks call it High-36, the same thing under a different name — — “whether or not consecutive” — in which your monthly basic pay was highest, divided by 36. Two consequences people miss: a promotion in the last year lifts the average by roughly a third of the raise rather than all of it, and allowances are not in it at all. BAH and BAS do not count, which is why retired pay lands lower than people expect against take-home.

The BRS trade, stated plainly

At twenty years the legacy multiplier gives 50% and BRS gives 40%. On a $9,000 high-3 that is $900 a month less pension, for life, COLA’d.

What you got in exchange is real and arrives decades earlier: an automatic 1% of basic pay into the TSP from your 60th day of service, and matching of up to 4% more once you pass 24 months. The regulation’s own table is worth reading closely, because the match is not linear — at a 4% contribution the match is 3.5%, and only at 5% do you get the full 4% and a 10% total going into the account. Contributing 4% instead of 5% gives up half a percent of pay every year, permanently.

The automatic 1% vests at the start of your 25th month. The matching vests immediately.

There is a third piece of the trade that is easy to miss: continuation pay. Somewhere between 7 and 12 years of service, a BRS member who agrees to serve at least three more years is paid a lump sum set as a multiple of monthly basic pay — by statute not less than 2.5 times monthly basic pay for the active component, and not less than 0.5 times for a drilling reservist, with the services free to pay more. It is a floor in law and a decision by your service in practice, so the multiple you are actually offered is the one to ask about, not the minimum.

Guard and Reserve: where a point comes from, and the rules that decide everything

Fifty points, or the year does not count. Two different tests run on the same points and people conflate them constantly. The first decides whether a year counts toward the twenty years you need to qualify at all, and the statute is blunt about it: it counts only if you were credited with at least 50 points in that one-year period. Below fifty, the year is not a bad year — it is not a year.

Points are credited on a short and specific list: one point for each day of active service; one point for each drill or period of equivalent instruction you attend; 15 points a year simply for membership in a reserve component; and one point for each day of funeral honors duty performed for at least two hours. Membership alone gets you 15 of the 50, which is why a standard drill year clears the bar comfortably and a year you mostly missed does not.

The second test caps what the points are worth. When those points are converted into years for the retired-pay computation, the ones that came from drills and from membership are capped at 130 days in a year of service. That ceiling has moved over a career: 60 days before the year containing 23 September 1996, then 75, then 90, and 130 from the year containing 30 October 2007 onward. Days of actual active service are counted under a different clause and are not subject to that cap — which is the arithmetic reason a mobilisation is worth so much more to a reserve pension than an unusually busy drill year.

Points divided by 360. The regulation is precise about the arithmetic: carry to three decimals, round to two. Its example is 4,735 points becoming 13.152 and then 13.15 years. A drilling year of roughly 75–90 points therefore buys about a quarter of a year of multiplier, which is why twenty good years of Reserve service produces a much smaller pension than twenty years active.

Sixty, minus your deployments. The default age is 60, but the statute reduces it “by three months for each aggregate of 90 days” of qualifying active service in a fiscal year after 28 January 2008. Two years of mobilisation moves the date by two years. Almost nobody tracks this themselves, and it is worth checking against your own orders before assuming 60.

And then you wait. A reservist who has qualified but has not reached the eligibility age is in what everyone in the community calls the gray area — retired from drilling, not yet drawing retired pay. It is not a statutory term and nothing is wrong when you are in it, but it is worth knowing the phrase, because the ID card, the benefits and most of the guidance you will be handed are indexed under it.

The lump-sum election

What this does not include

Disability retirement percentages — the Chapter 61 computation, which is a different formula and not this one — REDUX, the SBP premium if you elect it, and the VA offset if you receive disability compensation. The survivor election is the largest of those and has its own page: what SBP costs and what it buys.

If a federal civilian career followed the uniform, the two systems meet: the FERS annuity and how a federal pension sequences against Social Security and the TSP. And the TSP question is the same one either way — whether to keep it or roll it.
