Does this calculate the tax I owe?

No — this shows only the gain or loss itself and whether it’s short- or long-term by holding period. Actual tax owed depends on your income, jurisdiction, and filing situation, which this tool doesn’t estimate.

Why does short-term vs. long-term matter?

In many countries (including the US), long-term holdings are often taxed at a lower rate than short-term ones — this tool just labels which category your holding period falls into.

Calculate the capital gain or loss on an investment and whether it’s short- or long-term.

Display currency

Changing the display currency only changes the symbol shown — amounts aren't converted, since this tool doesn't use live exchange rates.

This calculates your capital gain (or loss) only — the difference between what you paid and what you sold for. It does not estimate any tax owed on that gain, since tax rates depend on your income, jurisdiction, and filing situation.

How this is calculated

Capital Gain = Sale Price − Purchase Price. Holdings of 12 months or more are labeled long-term and under 12 months short-term (the common US convention) — this is a factual holding-period label only, not a tax calculation.
