To find the net gain or loss, subtract the purchase price from the current price and divide the difference by the purchase prices of the asset. For example, if you buy a stock today for $50, and tomorrow the stock is worth $52, your percentage gain is 4% ([$52 – $50] / $50).
Do you have to pay taxes if you lost money in the stock market?
Stock market gains or losses do not have an impact on your taxes as long as you own the shares. It’s when you sell the stock that you realize a capital gain or loss. The amount of gain or loss is equal to the net proceeds of the sale minus the cost basis.

To deduct your stock market losses, you have to fill out Form 8949 and Schedule D for your tax return.

Thus, if you lose $50,000 on one stock and make $50,000 on another, these gains and losses will offset each other. You won’t owe any taxes on your $50,000 in gains because of your equally sized losses. If your losses exceed your gains, you can write off up to $3,000 of the excess losses each year against your income.
