What Every Junior Enlisted Should Know About the TSP

The Thrift Savings Plan represents one of the most powerful wealth-building tools available to service members. Yet many junior enlisted personnel either ignore it or fail to maximize its benefits. Understanding the TSP early in your career can mean hundreds of thousands of dollars by retirement.

Why Start Now

Time is your greatest asset. An E-3 contributing $200 monthly starting at age 20 will have significantly more at retirement than an E-7 contributing $500 monthly starting at 35. Compound interest works best with decades to grow.

Consider this: $200 monthly for 40 years at an average 7% return becomes over $525,000. Starting ten years later with the same contributions yields roughly $240,000. The early starter earns over $285,000 more from compound growth alone.

Free Money Through Matching

Under the Blended Retirement System, the government matches up to 5% of your base pay. Contributing less than 5% means leaving free money on the table. At minimum, always contribute enough to capture the full match.

Roth vs Traditional

Junior enlisted members often benefit most from Roth TSP contributions. Why? Your current tax bracket is likely lower than it will be later in life. Paying taxes now on lower income means tax-free withdrawals in retirement when you’re potentially in a higher bracket.

Choosing Your Funds

The TSP offers several investment options:

Lifecycle Funds (L Funds) – Automatically adjust based on your target retirement date. The simplest “set it and forget it” option.

Individual Funds – C Fund (large companies), S Fund (small companies), I Fund (international), F Fund (bonds), and G Fund (government securities). These require more active management but offer customization.

Common Mistakes to Avoid

Keeping everything in the G Fund means minimal risk but also minimal growth. Young investors with decades until retirement can typically afford more aggressive allocations.

Withdrawing from your TSP during separation wastes years of potential growth and triggers taxes and penalties. Roll it over to an IRA or leave it invested instead.

Getting Started

Log into myPay to set up or increase your TSP contributions. Even $50 per paycheck makes a difference over a 20-year career. Increase contributions with each promotion or pay raise.

The TSP is not exciting, but it is effective. Building wealth through consistent contributions is one of the smartest financial moves any service member can make.
