How This Calculator Works
Enter the investable portion of your severance (after tax and after reserving what you need during your job search), the annual return you expect, and how long it will stay invested. The calculator compounds the lump sum and shows the ending value and total growth.
The Formula
Future Value of a Lump Sum
PV = present value, r = annual rate, n = number of years
Worked Example
$40,000 of investable severance at 6% for 10 years grows to about $71,634 — nearly doubling, with $31,634 of growth. The critical first step, though, is reserving enough severance to cover living expenses during the gap before your next job — only the surplus beyond that buffer should be invested. Severance is also typically taxable as income, often with a chunk withheld, so invest the net amount, not the gross.
Key Insight
Severance pay arrives at a financially vulnerable moment — a job loss — so the priority order matters more than the investment growth. First, secure your safety net: estimate how many months you may be without income and reserve that much (severance plus existing emergency fund) in safe, liquid savings before investing anything. Job searches often take longer than expected, and you may also lose employer health coverage (factor COBRA or marketplace premiums into your buffer). Second, handle the tax reality: severance is generally taxable as ordinary income, frequently with mandatory withholding, and a large lump sum can push you into a higher bracket for the year — so invest the after-tax amount and consider whether tax-advantaged accounts (an IRA, if eligible) fit. Third, pay down high-interest debt before investing the surplus. Only the money beyond your safety net, after taxes and high-interest debt, should go into long-term investments — and there, this calculator's compounding applies, with the usual caveats that it's a nominal return before inflation and markets aren't smooth. Treated this way, the investable slice of a severance can meaningfully boost long-term wealth without compromising the security you need during the transition.
Severance tax treatment
Severance pay is taxable wages. Federal withholding: typically supplemental wage rate 22% (for portions up to $1M) or 37% (above). State withholding varies. FICA (Social Security + Medicare): 7.65% on portion up to Social Security wage base.
For $50K severance: ~$11K federal + state withholding + $3,800 FICA = $14,800 total tax withholding. Net to employee: ~$35,200.
Final tax bracket determined at year-end. If severance pushes total income into 32% bracket: $50K × 32% = $16K total tax + FICA. Withholding of 22% supplemental rate may be insufficient — employee owes more at tax filing.
Strategy: maximize 401(k) catch-up contribution if eligible (last paycheck or via separation contribution if plan allows). Reduces taxable income. Roll severance into IRA isn't possible — severance is wages, not retirement plan distribution. Consider Roth conversion in year of severance if income still moderate (transition between jobs may produce lower-income year).
Severance allocation — cash needs vs investment
Recommended severance allocation. (1) IMMEDIATE NEEDS — set aside 3-6 months expenses for job search period. Don't deplete this through over-investment.
(2) HEALTH INSURANCE — COBRA premiums or marketplace ACA replacement. Cost: $700-$1,500/month family typical. Budget 12-18 months coverage.
(3) DEBT PAYDOWN — high-interest debt (credit cards >15% APR). Pay off before investing in stocks at expected 7-10% return. Even moderate-rate debt (auto loan, student loan) deserves consideration vs investing.
(4) EMERGENCY FUND TOP-UP — if not already 6 months expenses, prioritize building before investing.
(5) INVEST REMAINDER — after addressing above, invest remaining severance in retirement accounts (if income allows additional IRA contribution; 401(k) match opportunities at next employer) and taxable brokerage.
For most workers receiving 3-6 months severance, full investment isn't recommended. The cash provides critical bridge during transition. Investing remainder after needs addressed produces best financial outcome.
Severance investment scenarios
Reference severance growth if invested at 7% return after addressing immediate needs.
| Severance after taxes | Cash reserved (6 mo) | Investable amount | Value at 20 years |
|---|---|---|---|
| $30K | $25K | $5K | $19K |
| $50K | $30K | $20K | $77K |
| $100K | $40K | $60K | $232K |
| $150K | $50K | $100K | $387K |
| $250K | $60K | $190K | $735K |
| $500K | $80K | $420K | $1.62M |
For most workers, only portion of severance is reasonably investable after addressing immediate cash needs during job search transition. Higher severance amounts (executives receiving $500K+) can invest substantial portion. Always factor realistic cash needs into post-severance financial planning rather than treating entire severance as investable capital.
Frequently Asked Questions
How is the future value calculated?
The investable severance is multiplied by (1 + annual return) raised to the number of years. $40,000 at 6% for 10 years is $40,000 × 1.06¹⁰ ≈ $71,634.
Should I invest all my severance?
No — secure your safety net first. Reserve enough (severance plus emergency fund) in safe, liquid savings to cover living expenses for the months you may be without income, plus health coverage costs. Only the surplus beyond that buffer, after taxes and high-interest debt, should be invested.
Is severance pay taxable?
Generally yes — it's typically taxed as ordinary income, often with mandatory withholding, and a large lump sum can push you into a higher tax bracket for the year. Invest the after-tax amount, not the gross, and consider whether tax-advantaged accounts fit your situation.
What about health insurance during the gap?
Losing a job often means losing employer health coverage. Factor COBRA continuation or marketplace premiums into the buffer you reserve from severance, since healthcare can be a significant cost during a job search. This is part of the safety net to secure before investing any surplus.
What return should I assume?
Use a return matching how you'd invest the surplus — a diversified long-run figure (around 6%–7% nominal) for money you won't need for years, lower for shorter horizons. Remember it's nominal (before inflation) and not guaranteed, and only money beyond your safety net should be exposed to market risk.
When is this calculator unreliable?
When assuming entire severance amount can be invested without addressing immediate cash needs (3-6 months living expenses, COBRA health insurance, job search costs). Also unreliable when not accounting for tax impact (severance pushed into high marginal bracket can consume 30-40% of nominal amount).

Methodology & Review
Severance pay investment growth uses compound interest for lump sum invested. The calculator returns projected balance. Severance is typically paid as lump sum at job termination; recipient can invest the after-tax amount. Standard treatment: severance taxed as ordinary income in year received (typically pushed into high marginal bracket). RELIABILITY: Reliable for direct compound calculation. Less reliable as financial planning guidance because severance often comes with sudden job loss requiring current cash for living expenses, COBRA health coverage, job search costs — full investment of severance is often not possible.
