About this tool

US capital gains: held over 1 year = long-term at 0/15/20% (by income) + possible 3.8% NIIT over $200k; held under = short-term, taxed as ordinary income (10–37%). The difference on a $50k gain can exceed $5,000 — this estimator shows both scenarios side by side with editable rates so it stays honest as your bracket changes.
