How the result is calculated

Adjusted cost basis adds purchase price, entered acquisition costs and capital improvements. Net proceeds subtract entered sale costs; their difference is the estimated pre-tax gain or loss. Tax rates, depreciation, exemptions, currency effects and jurisdictional rules are excluded.

All calculation and transformation work happens in this browser tab. No entered value is sent to an Noler Tools application server.
