How to invest a $500,000 severance package
A severance check is one-time money with lifetime consequences. Half a million dollars dropped into your account creates two problems at once: tax (federal + state can wipe out a third of it) and deployment shock (lump sum or dollar-cost-average?). This guide walks you through the must-do steps — tax mitigation, cash buffer, allocation, lump-sum vs DCA — and gives you a concrete sample portfolio.
Step 1 — Get the tax piece right first
Severance is taxed as ordinary income in the US. On $500,000 you can easily face a marginal rate of 35–45 % once federal, state, and Medicare add together. Before you invest a single dollar, think about spreading the income across tax years and using deferral vehicles.
- Negotiate the timing. A January payout vs. a December payout can shift hundreds of thousands of dollars into a year with lower base income.
- Max out the 401(k) and HSA in the payout year — every $30,000 of pre-tax deferrals saves roughly $10,000 in tax at the top brackets.
- Open or fund a SEP/Solo 401(k) if you go independent next — the year of severance plus 1099 income is the perfect window.
- Talk to a CPA before you accept. A few hours of advice will routinely save 5–10× their bill at this size.
Step 2 — Set aside cash before anything goes into the market
Severance rarely shows up because everything is going great. There’s usually a stretch ahead with no paycheck. The first job is to cover 12–24 months of living expenses — only after that does anything go into stocks.
$500,000 gross does not mean $500,000 of investable capital. Realistic deployable amount is $200,000–$300,000. That is not loss — that is honest planning.
The exact split depends on age, income certainty, and risk tolerance. A 55-year-old taking early retirement should cut equity exposure (e.g. 40/50/10). A 35-year-old with a 30-year horizon can run 75/15/10.
Step 3 — Lump sum or dollar-cost average?
The hardest psychological question. The often-cited Vanguard study shows: in roughly two thirds of historical periods, lumping it all in immediately beat dollar-cost-averaging. But severance involves loss-asymmetry — a 30 % crash six months after deployment can break you mentally.
| Method | Upside | Downside | When it fits |
|---|---|---|---|
| Lump sum (all at once) | Highest expected return | Crash risk is brutal mentally | 30+ year horizon, iron stomach |
| 12-month DCA | Smooths the entry | Slightly lower expected return | Standard route for large sums |
| 24-month DCA | Maximum protection from a top crash | 2 years of cash drag | If you’re nervous, or near ATH |
| 50/50 split | Half now, rest over 12 months | Compromise | Pragmatic middle path |
For the typical case (six-figure severance, no second income lined up), a 12- to 24-month DCA is the honest answer — the few percent of expected return you give up is paid back many times over in not panic-selling at the bottom.
Sample allocation for $250,000 of investable capital
Assume you are mid-40s, 15+ years to retirement, want neither to gamble nor to lose to inflation:
| Building block | Weight | Amount | Function |
|---|---|---|---|
| VT / VTI + VXUS (global equities) | 50 % | $125,000 | Broad global, return engine |
| VWO (emerging markets) | 10 % | $25,000 | Diversification, Asia growth |
| BND / AGG (US aggregate bonds) | 20 % | $50,000 | Stabilizer, predictable yield |
| HYSA / T-bill ladder | 10 % | $25,000 | Crash-buying reserve |
| GLD / IAU (physical gold) | 10 % | $25,000 | Inflation / crisis hedge |
At 5 % nominal expected return over 15 years that grows to roughly ≈ $520,000, at 7 % around ≈ $690,000. After 2 % inflation about half of the nominal gain remains in real purchasing power.
Common mistakes with severance money
- Tax planning before investment. CPA hours pay for themselves
- 12–24 months of cash before anything goes into the market
- Spread across 2–3 brokers — Schwab, Fidelity, Vanguard
- DCA over 12+ months instead of one-shot deployment
- Written investment policy — allocation, dates, rebalancing rule
- Loading up on a “hot” single stock with half the proceeds
- Variable annuities, structured notes, or any product the bank pushes
- 1.0–1.5 % AUM advisor fees on what is fundamentally a 3-fund portfolio
- Buying a real-estate flip before the cash buffer is built
- Crypto allocation above 10 % at six-figure size
FAQ
How much tax will I actually pay on $500,000 severance?
Federal: marginal 35 % over $250k single, 37 % over $625k. Add Medicare surtax (0.9 % + 3.8 % NIIT) and state tax (0–13 %), and the all-in marginal hit reaches 45 %+ in California or NYC. Total bill on $500k stand-alone severance is typically $150,000–$220,000. Pushing the payout to a low-income year and stacking 401(k)/HSA/SEP deferrals can shave $30,000–$60,000 off.
Should I just buy a house with the severance?
Rarely the best move as a stand-alone strategy. A house concentrates 100 % of the capital into one asset class, in one location, with zero diversification. If it’s your primary residence, that’s defensible. As “investment”, $250,000–$500,000 split between a small rental and a global ETF portfolio is consistently the more robust play.
Which broker should I use for $500,000?
For US residents the standard answer is Schwab, Fidelity, or Vanguard — all three have SIPC coverage ($500k securities, $250k cash) plus excess insurance well above $1M. Splitting the assets across two of them is the simplest hedge against any operational outage. Trading apps with a single counterparty (Robinhood, Webull) are not the right vehicle for this size.
What about a Treasury-bill ladder for the cash portion?
Excellent choice for the bond/cash sleeve. Rolling 4-week, 13-week, 26-week, and 52-week T-bills creates a ladder that yields roughly the same as a money-market fund but with no credit risk. Treasury interest is also exempt from state income tax in the US — a meaningful pickup in California or New York.
Is hiring an advisor worth it at $500k?
For a vanilla three-fund portfolio: no — the typical 0.8–1.0 % AUM fee compounds to $100,000–$200,000 of foregone wealth over 20 years. Advisory fees become defensible when there is real complexity: stock-option exercise, business sale, multi-state tax planning, estate work. Even then prefer hourly fee-only CFP/CPA ($300–$500/hr) over AUM-based “wealth management”.
What if I’m close to retirement?
Use the bucket approach. Bucket 1 = 3–5 years of spending in HYSA/T-bills. Bucket 2 = 5–10 years in bond ETFs. Bucket 3 = the rest in equity ETFs. You never sell stocks during a crash — you draw from Bucket 1, wait for recovery, then refill. This structure protects against sequence-of-returns risk, which is the single biggest threat in the first 5–10 years of withdrawals.
Run the real numbers — tax, real return, DCA backtest
Before you push $250,000 into the market, it’s worth checking what’s actually left after tax and inflation, and how a 12-month DCA plan would have performed historically.
