Cost basis and tax lots:
What you paid, for accurate tax estimates

Cost basis is what you paid for an investment; tax lots are the separate purchases that make it up. Both decide your taxable gain.

PortfolioPilot shows an average cost basis per holding, matches lots first in, first out for tax estimates, and lets you add missing basis. Without basis, estimates show ranges instead of exact figures. Part of Gold.
