TSP Annuity vs. Commercial Annuity: Which Pays More for Federal Retirees in 2026?
When you're ready to convert your TSP into lifetime income, the government gives you one option: MetLife. The commercial market gives you fifty. Here's what that difference costs you — and how to make the right call.
Published April 21, 2026 · 10 min read
If you're a federal employee approaching retirement, you'll eventually face one of the biggest decisions in your financial life: what to do with your TSP balance.
One option is to convert part or all of it into guaranteed monthly payments for life — a move that sounds simple but hides a critical choice most retirees don't know they have.
The Thrift Savings Plan offers one annuity product, administered by one company (MetLife), priced at one interest rate index that currently averages 3.5% over the past four years.
The commercial market offers hundreds of companies, dozens of product designs, and — in April 2026 — interest rates near their highest levels in 15 years.
This piece breaks down exactly how both options work, what the numbers look like side-by-side, and the three questions that should drive your decision.
How the TSP Life Annuity Works
The TSP Life Annuity is a Single Premium Immediate Annuity (SPIA) purchased directly through your TSP account. The Federal Retirement Thrift Investment Board (FRTIB) contracts exclusively with MetLife to provide it — MetLife has held this contract since the TSP's inception.
The mechanics are straightforward:
- You direct some or all of your TSP balance toward an annuity purchase (minimum: $3,500)
- The TSP transfers those funds to MetLife
- MetLife begins sending you a fixed monthly payment — typically for the rest of your life
- The decision is irrevocable. Once done, it cannot be undone.
One thing to understand clearly: the federal government does not guarantee these payments. MetLife does, based on its own financial strength. The TSP doesn't back the promise — it simply arranges the purchase.
TSP Annuity Payout Rates in 2026
The monthly payment you receive is driven by three factors: your account balance, your age at purchase, and the TSP's annuity interest rate index (currently averaging approximately 3.5% over the past 48 months).
Here's what that translates to in dollars for a single life, level payment annuity:
| Age at Purchase | Monthly Payment per $100,000 | Annual Payout Rate |
|---|---|---|
| 62 | ~$639 | 7.67% |
| 72 | ~$817 | 9.80% |
| 82 | ~$1,241 | 14.89% |

The higher payout at older ages reflects actuarial math — the older you are, the fewer expected payments MetLife will make.
TSP Annuity Design Options
The TSP isn't quite as rigid as people think. You can customize your annuity with:
- Single or joint life (if joint, payments continue to a surviving spouse/annuitant at 50% or 100%)
- Level payments (fixed monthly amount) or increasing payments (1% annual COLA, but lower starting payment)
- Cash refund feature (if you die before receiving back your full premium, remaining balance goes to beneficiaries — reduces monthly payment)
- 10-year certain guarantee (payments continue to beneficiaries for 10 years minimum even if you die earlier — reduces monthly payment)
Each added feature lowers your base payment, so there are real tradeoffs to model.
How Commercial SPIAs Work
A commercial Single Premium Immediate Annuity works identically to the TSP version — you hand over a lump sum and receive guaranteed monthly payments for life — but you're buying from the open market instead of MetLife through the TSP.
In April 2026, that market is unusually attractive.
SPIA payout rates closely track 10-year Treasury yields and investment-grade corporate bond rates. With both significantly elevated compared to the 2012–2020 era, insurance companies can fund larger monthly payments. Current payouts are approximately 30–40% higher than what was available during that low-rate window.
Commercial SPIA Rates: April 2026
Here's what top-rated carriers are offering for a 65-year-old male purchasing a $250,000 single life, level payment SPIA:
| Carrier | Monthly Income | A.M. Best Rating |
|---|---|---|
| EquiTrust Life | $1,696 | B++ |
| Athene Annuity | $1,655 | A+ |
| Nationwide Life | $1,647 | A+ |
| Penn Mutual | $1,617 | A+ |
Source: InsuranceGeek SPIA Rate Survey, April 2026
Per $100,000, that translates to roughly $647–$678 per month for a 65-year-old male.
Note the spread between carriers: $79/month difference between EquiTrust and Penn Mutual — or $948 per year on the same $250,000 investment. That spread compounds over decades of retirement.
For a $100,000 investment, the 2026 SPIA payout picture at different ages looks like this (single life male, life-only):
| Age | Approximate Monthly Payment | Annual Payout Rate |
|---|---|---|
| 62 | $570–$610 | ~7.0% |
| 65 | $620–$678 | ~7.7% |
| 70 | $700–$760 | ~8.8% |

TSP vs. Commercial: The Side-by-Side
Let's compare what a typical FERS retiree sees at $100,000 invested, using available 2026 data:
| Factor | TSP MetLife Annuity | Commercial SPIA |
|---|---|---|
| Provider choice | MetLife only | 50+ carriers |
| Rate basis | 3.5% index (48-mo average) | Current market (~5–6%) |
| Age 62 payout (single life) | ~$639/mo | ~$570–$610/mo |
| Age 65 payout (single life) | ~$700/mo (est.) | ~$620–$678/mo |
| Payout shopping | None | Shop for best rate |
| Tax treatment on purchase | No tax event (TSP → MetLife) | No tax if rolled to IRA first |
| Government guarantee | No (MetLife backs it) | No (carrier + state guaranty fund) |
| State protections | N/A | Yes (up to $250K–$500K by state) |
| COLA option | 1%/year available | Multiple COLA options |
| Joint life options | 50% or 100% survivor | Multiple survivor %s |
| Minimum purchase | $3,500 | Varies (typically $10,000+) |
| Irrevocable | Yes | Yes |
| Legacy protection | Optional cash refund | Optional cash refund |
The rate comparison is nuanced. The TSP's 3.5% interest rate index is a 48-month backward-looking average — it significantly lags where commercial rates are today. A commercial SPIA bought in April 2026 is priced on current market rates, not a four-year average. That's a meaningful headwind for the TSP product in the current environment.
However, for ages below 65, the TSP may still show competitive payouts for its specific age brackets. The right comparison is always at your exact age and amount — don't rely on general tables.
The Path from TSP to Commercial Annuity
Many federal employees don't realize they can escape the MetLife single-quote problem. Here's how:
- At retirement, initiate a direct rollover from your traditional TSP account to a traditional IRA. No taxes due. No 60-day clock.
- Shop SPIA quotes from multiple carriers through a fee-only advisor, broker, or comparison platform (like our Annuity Marketplace).
- Purchase the SPIA using funds from your IRA. The payment structure is the same as buying directly — you pick your design, lock in the rate, and start receiving monthly payments.
One critical note on Roth TSP funds: rolling Roth TSP to a Roth IRA is possible with no immediate tax, but the five-year holding period rules are complex. If you have Roth TSP funds and are considering this path, work with a fed-expert financial planner before initiating the rollover. The TSP also launched in-plan Roth conversions in 2026, adding another layer of planning opportunity.
Tax treatment after rollover: Payments from an IRA-funded SPIA are 100% taxable as ordinary income at the federal level — same as payments from a TSP annuity purchased directly. No difference in ongoing tax treatment.
The FERS Pension Factor Most People Miss
Here's the conversation that changes everything for most FERS retirees:
You probably already have two guaranteed lifetime income streams — your FERS pension and Social Security. Both are inflation-adjusted (or partially so). Both are backed by the U.S. government. Both are irrevocable.
Adding a TSP annuity creates a third fixed income stream. For many FERS retirees, this raises a key question: do you need it?
Every dollar you annuitize is a dollar that:
- Cannot be accessed for emergencies or large expenses
- Cannot be invested for additional growth
- Cannot be passed to heirs without add-on features that reduce your monthly payment
- Cannot be Roth-converted in future years for tax diversification
Several major federal retirement planning advisors — including those with decades of practice advising FERS and CSRS employees — argue that federal retirees with both a pension and Social Security are already well-covered for base income, and that locking TSP money into a fixed annuity reduces flexibility without meaningful added security.
That said, this is a personal calculus. Some retirees genuinely have an income gap — their pension and Social Security don't cover their monthly expenses. Others have health conditions that make longevity-based products less attractive. Some simply value the simplicity of "check arrives, no decisions required."
The right answer isn't universal. It's yours.
Three Questions That Drive the Right Decision
1. Do you have an income gap?
Add up your guaranteed monthly income: FERS pension + Social Security + any CSRS survivor benefit or other fixed income. Subtract your monthly essential expenses. If there's a gap — meaning your guaranteed income doesn't cover your needs — an annuity (either TSP or commercial) is worth modeling. If there's no gap, keeping TSP funds invested and withdrawing via installments likely makes more financial sense.

2. Does the math favor annuitizing right now?
In April 2026, commercial SPIA rates are near 15-year highs. If you've been waiting for a good rate environment, this is it. The TSP annuity interest rate index (3.5% 48-month average) currently lags the commercial market — meaning if you're going to annuitize, buying commercially (via TSP rollover to IRA) likely offers better terms than buying through the TSP directly.

3. How much do you value flexibility vs. certainty?
If you want maximum simplicity and are comfortable with MetLife's credit strength, the TSP annuity is the fastest path. If you want to shop the market, customize your design, or maintain some legacy protection, the commercial route (via IRA rollover) gives you more options. Neither is wrong — they serve different priorities.
When TSP Annuity Makes Sense
- You want maximum simplicity (single transaction, no rollover paperwork)
- Your TSP balance is modest (under $50,000) and the rollover process isn't worth it
- You've already modeled the MetLife quote and it meets your income needs
- You're comfortable with MetLife's financial strength as your guarantor
- You want to keep a portion in TSP installments and annuitize only a small slice
When Commercial SPIA Makes Sense
- You want to shop multiple carriers and maximize your monthly payout
- You're buying in April 2026 (favorable rate environment — commercial rates lag the TSP index's backward average)
- You want more design flexibility (COLA riders, specific survivor percentages, period certain options)
- You have a larger balance where rate shopping could mean hundreds of dollars monthly
- You want to roll to a Roth IRA first for long-term tax planning before annuitizing
What the Experts Say
Advisors who specialize in federal retirement consistently flag the same points:
Against TSP annuity for most FERS retirees: "FERS retirees need to think about not putting more money in a fixed annuity, but increasing the purchasing power of the other money that they have, i.e. their investments in the TSP." — Art Stein, CFP, Arthur Stein Financial (Federal News Network, 2024)
On the TSP annuity's limitations: "TSP annuities are inappropriate for most federal retirees precisely because they also have both a defined benefit pension and Social Security." — STWS financial planning staff (Federal News Network)
On the current rate environment: "Top SPIA quotes in our April 2026 survey sit far above the 2012–2016 era for comparable cases, and carrier spreads on the same inputs can still be hundreds of dollars a month — so shopping matters as much as timing." — InsuranceGeek SPIA Rate Survey, April 2026
The Bottom Line
In April 2026, the commercial SPIA market is offering rates that may outpace what the TSP delivers through its backward-looking rate index. Shopping matters — the spread between the highest and lowest-paying carrier on a $250,000 purchase can be nearly $1,000 per year.
But the bigger question isn't which annuity pays more. It's whether you should annuitize at all.
If you have a genuine income gap after accounting for your FERS pension and Social Security — and you want guaranteed income to cover it — an annuity purchase (commercial or TSP) is worth serious consideration in today's rate environment.
If you're already covered by your guaranteed income and your TSP is being used for discretionary expenses and legacy goals, the flexibility of installment withdrawals or IRA drawdown may serve you better than locking up principal forever.

Frequently Asked Questions
How much does the TSP annuity pay per $100,000 in 2026? The TSP MetLife annuity pays approximately $639 per month per $100,000 invested at age 62, $817 per month at age 72, and $1,241 per month at age 82. These are based on a single life, level payment design using the TSP's annuity interest rate index, which averages around 3.5% over the past 48 months.
Can federal retirees roll their TSP into a commercial annuity? Yes. Federal retirees can roll their TSP into a traditional IRA via direct rollover — with no immediate tax consequences — and then use those IRA funds to purchase a commercial Single Premium Immediate Annuity (SPIA) from any licensed insurance carrier. This allows retirees to shop 50+ carriers instead of accepting MetLife's single quote.
Do commercial SPIAs pay more than the TSP annuity in 2026? In April 2026, top-rated commercial SPIA carriers are offering 30–40% higher payouts than the 2012–2020 era, with 65-year-old males receiving approximately $620–$678 per month per $100,000 from A-rated carriers. Because the TSP's annuity interest rate index (3.5%) is a backward-looking 48-month average that lags today's market rates, competitive commercial SPIAs may offer modestly higher payouts for comparable designs — plus the ability to shop multiple carriers.
What happens to my money if I die early after buying a TSP annuity? With a basic single life TSP annuity, if you die early your remaining funds stay with MetLife and nothing passes to your heirs. To protect against this, the TSP offers optional features including a cash refund (returns remaining principal to beneficiaries) and a 10-year certain guarantee (payments continue for 10 years minimum). Both features reduce your monthly payout. Commercial SPIAs offer similar options.
Should FERS retirees buy a TSP annuity? Most FERS retirees already have two guaranteed income streams: a FERS pension and Social Security. Many financial advisors argue that adding a third fixed income stream (TSP annuity) reduces flexibility without meaningful added security. However, for retirees with a large TSP balance and a genuine income gap — or those who want maximum simplicity — either the TSP annuity or a commercial SPIA may be appropriate. The right answer depends on your specific income picture.
