From saving to spending: the new problem
Retirement reverses your relationship with the TSP. For decades you added money and let it grow. Now you take money out, and the goal shifts to making it last. Sustainable income depends on what your balance can fund through bad markets, not on average returns.
That shift is harder than it sounds. A plan that works in average years can still fail if a downturn hits early. So the question is not just how much you have, but how fast you can safely spend it.
Three things shape your drawdown. Your TSP withdrawal options set how you take money out. A withdrawal-rate rule of thumb sets a sustainable pace. And required minimum distributions eventually force a minimum withdrawal.
This lesson walks through each. We explain the mechanics and the tradeoffs rather than prescribe a strategy, since the right plan depends on your income, your taxes, and your outlook.
How is taking money out of the TSP different from saving?
Saving is about contributions and growth; spending is about not running out. In retirement you reverse the flow, drawing income from a balance that still rises and falls with the market. The danger is a market drop early in retirement, while you are withdrawing. Your job shifts from growing the balance to setting a sustainable pace that lasts as long as you do.
Can the TSP run out if I withdraw too fast?
It can. The TSP is your money, not a lifetime guarantee, so a high withdrawal rate combined with weak markets can drain it. That is why retirees use a sustainable withdrawal pace and watch the early years closely. Some convert part of the balance into a guaranteed annuity to cover essentials. The rest of this lesson covers the options and the pacing.
What are your TSP withdrawal options?
You have several ways to take money from the TSP, and you can combine them. Since the TSP Modernization Act, the rules are flexible. You can take installment payments, single withdrawals, a life annuity, or a full payout or rollover.
Installments are the common income stream. You can set monthly, quarterly, or annual payments, as a fixed dollar amount or based on your life expectancy. You can start, stop, or change them at any time.
Single withdrawals and rollovers add flexibility. You can take one-time partial withdrawals whenever you need a lump sum, even while installments run. You can also move part or all of the balance to an IRA.
A TSP life annuity trades flexibility for certainty. You can use part or all of your balance to buy a life annuity, which pays a guaranteed monthly amount for life. The trade is that the money is locked in and no longer yours to draw from.
Four ways to draw from your TSP
| Option | How it works | Flexibility |
|---|---|---|
| Installments | Monthly, quarterly, or yearly payments | Start, stop, or change anytime |
| Single withdrawals | One-time partial payouts | Take them when you need them |
| Roll to an IRA | Move part or all to an IRA | Leaves the TSP |
| TSP life annuity | Guaranteed monthly income for life | Locked in, not reversible |
What are the TSP withdrawal options after I retire?
You can take installment payments, single partial withdrawals, a life annuity, or a full payout or rollover. You can also mix them. Installments give a regular income you can change anytime. Single withdrawals cover one-time needs, and a life annuity converts part of the balance into guaranteed monthly income. The TSP Modernization Act made these options far more flexible than the old rules.
Can I take money from my TSP more than once?
Yes. Since the TSP Modernization Act, you can take multiple partial withdrawals, even while installment payments are running. You are no longer limited to a single withdrawal. You can also choose whether the money comes from your traditional balance, your Roth balance, or proportionally from both. This flexibility lets you match withdrawals to your needs.
What is a TSP life annuity?
It uses part or all of your TSP balance to buy a guaranteed monthly income for life. The TSP annuity provider pays it. You can choose a single life annuity or one that also covers a spouse. The tradeoff is that the money is locked in: you trade access to the balance for certainty of income. It is one tool among several, not a default.
What is the 4% rule?
The 4 percent rule is a rule of thumb for how fast to spend a retirement portfolio. You withdraw about 4 percent of your starting balance in year one, then adjust that dollar amount for inflation each year. The aim is income that lasts roughly 30 years.
It came from historical research. Studies of diversified portfolios over long periods found that a pace near 4 percent usually survived even bad stretches. The exact number matters less than the idea: spend at a rate your balance can sustain through downturns.
It is a guideline, not a guarantee. Markets, your mix of investments, and how long you live all change the math. Some retirees use a lower rate to be safe; others adjust their spending up and down as markets move.
Treat it as a starting point. The 4 percent rule gives you a sane anchor to plan around, not a promise. Pair it with your FERS pension and Social Security, which cover part of your needs and ease the pressure on the TSP.
How does the 4 percent rule work?
You take about 4 percent of your TSP balance in your first year of retirement. After that, you raise the dollar amount with inflation each year, rather than recomputing 4 percent of the new balance. The goal is a steady, inflation-adjusted income that lasts around 30 years. It is a planning rule of thumb, not a guarantee that the money will last.
Is the 4 percent rule safe?
It is a guideline based on history, not a promise. It held up in past market downturns, but future returns, your investment mix, and your lifespan can all change the outcome. Many retirees treat 4 percent as a starting point and adjust. They spend less after a bad market year and more after a good one. Your FERS pension and Social Security also reduce how much you must lean on the TSP.
Does the 4 percent rule apply if I have a FERS pension?
Your FERS pension and Social Security change the picture. They cover part of your spending for life, so the TSP often fills a gap rather than funding everything. That can let you take a smaller percentage from the TSP, or give you room to spend more flexibly. The rule of thumb works best as a check on whether your TSP pace is sustainable, not as a rigid limit.
When are withdrawals required?
At some point, withdrawals stop being optional. Required minimum distributions (RMDs) force you to start taking money from your traditional TSP at a set age. The age is currently 73, and it rises to 75 in 2033.
RMDs apply to your traditional balance. Once you reach the RMD age, the IRS sets a minimum you must withdraw each year. It is based on your balance and life expectancy, and you can always take more.
Roth TSP no longer has RMDs. As of 2024, your Roth balance is not subject to RMDs while you are alive. Only your traditional balance counts toward the required amount, which can lower your RMD if you hold both.
Plan for RMDs early. They can push up your taxable income later in retirement, sometimes more than you need to spend. Many retirees coordinate earlier withdrawals or Roth conversions to soften the RMD years. A tax professional can help you map it out.
When do I have to start taking money out of my TSP?
You must begin required minimum distributions from your traditional TSP at the RMD age. That age is currently 73 and rises to 75 in 2033. The IRS sets the minimum each year based on your balance and life expectancy. You can always take more than the minimum. The requirement applies to your traditional balance, not your Roth balance.
Does the Roth TSP have required minimum distributions?
No, not anymore. As of 2024, Roth TSP balances are no longer subject to RMDs during your lifetime. Only your traditional balance counts toward the required amount. If you hold both, this can reduce your RMD compared with the old rules. Your Roth money can keep growing untouched until you choose to use it.
What happens if I miss a required minimum distribution?
A tax penalty applies to the amount you failed to withdraw on time. Recent law reduced that penalty, and it can be reduced further if you correct the shortfall promptly. Still, it is an avoidable cost. Setting up automatic installment payments that satisfy the RMD is a common way federal retirees avoid missing one.
Why the early years matter most
The first few years of retirement carry outsized weight. A market drop early on, while you are withdrawing, can do lasting damage that good later years cannot fully repair. This is called sequence-of-returns risk.
The reason is simple. Selling investments to fund income during a downturn locks in losses and leaves less to recover. Two retirees with the same average return can end up very differently, depending on when the bad years hit.
It changes how you draw down. Two common approaches help. One is holding a cushion of stable assets to draw on during downturns, so you avoid selling stocks low. The other is shifting toward stable funds near retirement and trimming withdrawals after a bad year.
Tools exist to test this. Monte Carlo simulation runs your plan through many market sequences, including bad ones, to gauge how often it lasts. A dedicated lesson covers sequence risk in more depth.
What is sequence-of-returns risk?
It is the risk that the order of market returns, not just the average, sinks your plan. A few bad years early in retirement, while you are withdrawing, can permanently shrink the balance. The same returns in a different order might be harmless. Because you are selling during the downturn, the early years matter far more than later ones.
How do I protect against a bad market early in retirement?
A few approaches help. One is holding a cushion of stable assets to draw from during downturns, so you avoid selling stocks low. Another is trimming withdrawals after a bad year. Keeping some growth investments helps the balance recover over a long retirement. Your FERS pension and Social Security also provide income that does not depend on the market. We describe the approaches rather than recommend one.
How to think about your withdrawal plan
A good withdrawal plan starts with your other income, then sets a TSP pace to fill the gap. Your FERS pension and Social Security cover part of your needs for life. The TSP covers the rest, at a rate you can sustain.
Weigh a few factors. How much guaranteed income you already have, how flexible your spending is, your tax picture across traditional and Roth, and how long you expect to need the money all shape the plan.
Questions worth working through:
Your TSP withdrawal plan ties into your whole retirement picture. To see how your pension, Social Security, and TSP fit together, run your free readiness score. For market risk, a Monte Carlo simulation can stress-test the plan. We explain the tradeoffs; the right plan is yours to choose.
- Income floor. How much do your pension and Social Security already cover, and what gap is left for the TSP?
- Flexibility. Can you spend less after a bad market year, or do you need a steady amount?
- Taxes. Drawing from traditional versus Roth, and timing around RMDs, changes your tax bill.
What is the best TSP withdrawal strategy?
There is no single best strategy; it depends on your situation. Start with the income your pension and Social Security already provide, then set a TSP pace to fill the gap sustainably. Consider your spending flexibility, your traditional and Roth balances, and your tax picture. We lay out the options and tradeoffs rather than recommend one, because the right plan turns on your own numbers.
Should I buy a TSP annuity or take installments?
Each fits a different need. A life annuity gives guaranteed income for life but locks in the money. Installments keep your balance accessible and adjustable, but leave you exposed to markets and to outliving the money. Some retirees annuitize enough to cover essentials and keep the rest flexible. We describe the tradeoff rather than advise a choice.
How do I make my TSP last through retirement?
Set a sustainable pace, lean on your pension and Social Security for the income floor, and watch the early years for market risk. Keep some stable assets to draw from in downturns, and plan around RMDs and taxes. Our free readiness score and Monte Carlo tools can test how long your plan lasts. The goal is income that holds up through good and bad markets.
