Don’t Wing It: Create you TSP Investment Policy Statement
As a federal employee, you’re no stranger to structure and planning—after all, your benefits, service credits, and retirement system are built on structure and timelines.
But what about your TSP? What about your other investments?
If you’re like many federal employees I know, you’ve been managing your own retirement savings for quite a while. You’ve probably been contributing to the Thrift Savings Plan (TSP) for years, choosing between the C, S, I, G, and F Funds, maybe even dabbling in the L Funds or the new Mutual Fund window. You might also have a Roth IRA or brokerage account on the side.
But here’s the question: Do you have a well thought out, written strategy that ties it all together?
That’s why one of the first steps we take with our clients is developing your TSP Investment Policy Statement (IPS)—a strategic guide that documents how your portfolio will be designed, managed, and adjusted over time.
In this post, I’ll walk you through how to build your own IPS, how it applies specifically to your TSP, and why it’s so important to your retirement.
What Is a TSP Investment Policy Statement
Let’s start at the beginning. A TSP Investment Policy Statement is a written roadmap that connects your portfolio to your purpose.
At its core, it answers three big questions:
- Why are we investing this money?
- What kind of return do we need to succeed?
- How do we manage the portfolio to stay on track?
We use this tool to define the guardrails for how your portfolio is built, what types of investments it will include, and how we’ll make decisions going forward. Think of it as your investment constitution—clear, personalized, and built to weather the storms.
Building your TSP Investment Policy Statement
Step 1: Aligning the Portfolio with Your Goals
It all starts with why.
If you haven’t done so already, you want to document your specific financial goal for the underlying investments.
For example, thinking of your TSP, you could say retiring at 62 with $6,000/month after taxes—is your why. You could clarify this further by indicating how long you think this money needs to last. (e.g., how long do you expect to be in retirement)
You might be 3 years from retirement but expect to be in retirement for 25 years so the money needs to last 28 years and accommodate for inflation.
We are off to a good start.
Step 2: Identify Your Personal Index Number (PIN)
Now that you know your goals with greater specificity, you need to do some quick math to determine how your portfolio needs to grow, for you to reach your goals.
General terms like ‘Grow my money’ or ‘Don’t lose my money’ are not enough here. We need an actual number. Advisors called this a targeted rate of return. We call it a Personal Index Number. (PIN)
Let’s say after you’ve crunched the numbers, your plan requires a 6.0% annual average return to succeed. That 6% becomes your PIN and becomes your goal now—not beating the C Fund, matching the L 2055, or beating Mike in accounting.
Your PIN anchors your portfolio to purpose, not performance hype. It also helps you evaluate whether you’re taking too much—or too little—risk in your current allocation
Which bring us to the most critical step.
Step 3: Know Thyself.
Once you know the rate or return you need to accomplish the goal for which you are investing the money, you need to assess how much risk you can realistically handle to get there. We call this a Risk Fingerprint, but it is more commonly called a risk tolerance.
A Risk Tolerance is your personal ability and willingness to endure losses or volatility in your investments in exchange for the potential of higher returns.
In simpler terms, it answers the question:
“How much market ups and downs can I stomach before I start to lose sleep… or do something I’ll regret?”
But in reality, there Are really Three Kinds of Risk Tolerance:
- Emotional Tolerance
How you feel when the market drops. Do you shrug it off—or panic and want to sell everything? This is about your mindset, your temperament, and your comfort with uncertainty. - Financial Tolerance
How much risk you can actually afford to take. If you’re 35 and not retiring for decades, you can likely weather more ups and downs than someone drawing income in retirement. - Required Risk
How much return (and therefore risk) you might need to take in order to reach your financial goals—based on your savings, time horizon, and desired lifestyle.
A good investment plan—and a sound TSP Investment Policy Statement (IPS)—balances all three.
Don’t skip this step. Why it matters
If your portfolio is too aggressive for your emotional tolerance, even if it’s tied to your rate of return you need, you may sell out of fear during a downturn—locking in losses and underperforming your retirement plan.
If it’s too conservative, you may not earn enough over time to meet your PIN.
Bottom Line
Risk tolerance isn’t about being fearless—it’s about knowing yourself, your timeline, and your goals, then investing in a way you can stick with through thick and thin.
⚙️ If you haven’t taken a risk assessment before—or if it’s been a while—this is a great first step toward aligning your investments with your actual comfort zone.
Step 4: Structuring the Portfolio
Once we’ve defined the destination, the outcome and the risk, we can build the vehicle to get you there.
We call this your Asset Allocation – this is how you divide your money among different types of investments—like stocks, bonds, and cash—to match your goals, timeline, and risk tolerance.
The Main Ingredients
Here are the most common asset classes:
- Stocks (Equities) – Provide long-term growth but come with more risk and volatility
Example: TSP C, S, and I Funds - Bonds (Fixed Income) – Offer more stability and income, but usually lower returns
Example: TSP F Fund - Cash & Cash Equivalents – Very stable, low risk, low return
Example: TSP G Fund
Why It Matters
Your asset allocation drives most of your long-term investment returns—not the individual stocks or funds you pick.
It also determines how your portfolio behaves during market ups and downs. For example:
- A portfolio that’s 80% stocks and 20% bonds will grow more over time but can drop more in a downturn.
- A 50/50 portfolio is more stable but may grow slower.
- A 100% G Fund portfolio may feel safe—but might not outpace inflation long-term.
Don’t Forget!
Remember, both the risk score and PIN need to be aligned with your asset allocation. If your PIN is 8% but your portfolio is 100% G-Fund, you might not accomplish your overriding goal. If so, you’ll need to course correct to align your asset allocation to your goals.
Step 5 Establish Investment Guidelines: In advance
This is where you create your personal investment rulebook.
Your IPS should outline exactly what you believe and how you’ll make decisions about your investments and more importantly, how you won’t. You’re deciding these rules in advance, when you’re thinking clearly, not when the markets are in chaos or your emotions are running high.
If you believe in staying the course, not timing the market, diversifying and ignoring short term market fluctuations, you’re off to a good start. You just need to put that in writing.
So, when your coworker charges into the breakroom yelling,
“You HAVE to move everything to the G Fund before the election or ELSE!”
…you can smile, sip your coffee, and remember that your plan is already built to withstand temporary noise.
Why This Matters for Federal Employees
Federal employees like you face a unique set of planning challenges: balancing a pension, managing TSP accounts, planning for survivor benefits, and coordinating retirement income across multiple sources. That complexity makes it easy to fall into fragmented or reactionary investing.
A well-crafted IPS brings clarity to the noise and cohesion to the plan.
It:
✅ Grounds your investment strategy in purpose
✅ Helps you tune out market distractions
✅ Serves as a safeguard against impulsive decisions
✅ Coordinates all your investment accounts around one goal
✅ Gives you a shared framework for decision-making
Final Thoughts on Creating a TSP Investment Policy Statement
As your career advances or your retirement gets closer, the margin for error shrinks. Whether you’re five years from retirement or five months into it, having an Investment Policy Statement gives your financial life the structure, discipline, and clarity it deserves.
At Mission Point, we build IPS documents into every long-term financial plan. It’s one of the ways we help federal employees like you build, safeguard, and enjoy their wealth—with purpose. However, every federal employee could benefit from an IPS, not just those working with a financial advisor.
