How Military Pay Increases Work: Promotion, Time in Service, and the Annual Raise

People often ask why their base pay went up — or why a buddy at the same rank takes home more. The answer is that military pay isn’t one number that sits still. It moves on three separate tracks, and understanding each one tells you exactly when your next raise is coming. Let’s walk through all three with real 2026 numbers.

1. Promotion: Moving Up a Pay Grade

This is the raise everyone thinks of first. When you promote — say E-4 to E-5, or O-2 to O-3 — you jump to a higher row on the pay table, and your base pay goes up immediately on the effective date of the promotion.

Here’s a real 2026 example. An E-4 with 4 years of service earns $3,658.50 a month in base pay. Pin on E-5 at that same 4 years of service and base pay becomes $3,946.80 — an extra $288.30 a month, or about $3,460 a year, and that’s before BAH and BAS, which often increase too because allowance rates differ by rank.

The higher you climb, the bigger the jumps tend to get. Promotions are the single largest lever you control over your military income, which is why they matter far beyond the extra stripe.

2. Time in Service: The Raises You Get for Sticking Around

Even if you never promoted again, your base pay would still climb. The pay tables are built with columns for years of service — 2, 3, 4, 6, 8, 10, 12 and onward — and you step up automatically each time you cross one of those marks in your current grade. This is called longevity pay, and it shows up on your LES without you doing anything.

Take a 2026 E-5. At 2 years of service, base pay is $3,598.20. Same rank, but at 8 years of service, it’s $4,299.90 — a $701.70 monthly difference earned purely through time in service, no promotion required. The increases aren’t evenly spaced, and eventually each grade “tops out” (an E-5, for instance, stops rising after 12 years), which is one reason the system rewards continued promotion.

3. The Annual Pay Raise (and Why It’s Not COLA)

Every January, the entire pay table gets bumped up by an across-the-board percentage set in the annual defense budget. This raise is tied to the Employment Cost Index (ECI), which tracks private-sector wage growth. For 2026, the active-duty pay raise is 3.8%, and it applies to every grade from E-1 to O-10.

The math is simple: it’s a percentage added to your base pay. On a $4,000 base, 3.8% is about $152 a month more — and because next year’s raise is calculated on the new, higher number, these increases compound over a career.

Here’s the part that trips people up: the annual pay raise is not the same as COLA. COLA — the cost-of-living adjustment — is a separate increase that applies to military retired pay and VA disability compensation, not active-duty base pay. For 2026, COLA is 2.8%, a different number set by a different formula (the Consumer Price Index). So if you’re still serving, the figure that moves your paycheck is the 3.8% pay raise; if you’re retired or drawing VA disability, the 2.8% COLA is the one that matters.

Putting It Together

In a strong year, all three can stack. Imagine an E-4 who promotes to E-5, crosses a longevity step, and gets the January raise in the same 12 months — that’s three increases compounding at once, and it’s why pay can suddenly feel very different year over year. The promotion and longevity pieces are largely up to you and your timeline; the annual raise is decided for you. Knowing which is which makes it a lot easier to plan a PCS, a re-enlistment, or a big purchase.

The fastest way to see exactly where you stand is to run your own grade, time in service, and location through the calculator — it pulls the verified 2026 base pay, BAH, and BAS in one place.
