Got a windfall — an inheritance, a bonus, a settlement, a sale? Windfall
Allocator helps you see what it's actually worth after taxes, then plan where
it goes.
HOW IT WORKS
1. Enter the amount and your state.
2. See an instant estimate of federal and state income tax, side by side with
your net amount.
3. Split the net amount across five categories — Investments, Family Savings,
Giving, Long-Term Savings, and Cash — using simple sliders and a live
donut chart.
4. Save as many named scenarios as you want, so you can compare "what if I
put more into investments" against "what if I gave more away" before you
decide anything for real.
WHY IT'S DIFFERENT
Most tax calculators stop at "here's what you owe." Windfall Allocator goes
one step further and helps you actually plan the rest of the decision — how
much to invest, how much to save, how much to give, and how much to keep
liquid — all in one place, updating live as you adjust.
PRIVACY FIRST
Everything you enter stays on your device. There's no account, no login, no
ads, and nothing is ever sent to a server. Full privacy policy available in
the app listing.
NOT TAX OR FINANCIAL ADVICE
Windfall Allocator is an educational calculator, not tax, legal, financial,
or estate planning advice. Tax figures are estimates based on published
federal and state rates and don't account for deductions, credits, or filing
statuses other than single. Always confirm with a qualified professional
before making financial decisions.
Estimate windfall taxes by state, then plan your savings and giving split.
