That is a combined federal + provincial marginal shortcut from the rate labels above. Tax on a gain is half the gain times that rate. A $50,000 gain in Ontario is about $6,688 - not $13,375.
If sale is below purchase, tax is zero here. Real filing can apply capital losses against other gains. This tool does not model that.
