Donating long-term appreciated stock to charity unlocks three benefits at once: a fair-market-value deduction, zero capital gains tax on the appreciation, and a clean rebalancing event for concentrated positions. Charity nets the same amount either way. Donor keeps 20-30% more of the value. This tool runs the side-by-side.
FMV, cost basis, and holding period are the three things that determine whether this is a good gift to make in stock — or whether you should sell first and gift cash (almost never the right call when long-term gain is large).
Federal capital-gains rate, state rate, and NIIT applicability — these set the size of the tax that Path A creates and Path B avoids.
Side-by-side: sell-then-donate (the wrong way) vs. donate-direct (the right way). Charity nets the same in both. Donor doesn't.
The deeper material lives in the two companion guides. Both are free. Both are written for practitioners — the donors who deploy concentrated wealth into mission, and the advisors who structure it.
