Capital gains tax$750.00
Capital gain$5,000.00
Net proceeds after tax$14,250.00
Capital gain = sale price − purchase price, and the tax is gain × rate ÷ 100. Buying at $10,000 and selling at $15,000 is a $5,000 gain; at a 15% rate the tax is $750, leaving $14,250 in proceeds. A negative gain is a capital loss (no tax). Real rates depend on how long you held the asset and your income — this is an estimate, not tax advice.

Questions
How is capital gains tax calculated?
Subtract the purchase price from the sale price to get the gain, then multiply by the rate. A $5,000 gain taxed at 15% is $750.
What if I sold at a loss?
If the sale price is below the purchase price the gain is negative — a capital loss — and there is no capital gains tax. Losses can sometimes offset other gains; check local rules.
