The calculator stacks your capital gain on top of ordinary income, applies the federal 0 / 15 / 20% long-term brackets, layers NIIT at 3.8% for MAGI over $200k, and adds your state rate.
This tool is educational. It uses 2025 single-filer federal brackets, a simplified state-tax model, and does not substitute for a CPA review of your specific facts. For a second set of eyes on a meaningful event, match with a fiduciary advisor who routinely works with equity compensation.
