Severance Investment Calculator: Future Value of Invested Severance
Work out what severance pay could grow to if you invest the portion you don't need for living expenses — the future value and the growth it earns over the years it stays invested.

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.
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.

Methodology & Review
Future value is the lump sum compounded at the annual return over the period. It assumes the after-tax severance is invested at once and left untouched at a constant return; it ignores fees, taxes on gains, inflation, and any portion needed for living expenses during a job search.
