Calculating Percentage Change
To find the percentage gain or loss, you take the difference between the end price and start price, divide it by the start price, and multiply by 100.
Percentage Change = ((End Price - Start Price) / Start Price) × 100
Frequently Asked Questions
How do I calculate a percentage loss?
Use the same percentage change formula. If the ending price is lower than the starting price, the result is negative, which means the trade or investment lost value.
What is a good percentage gain for a stock trade?
It depends on the strategy, risk, and time frame. A short-term trade might target a smaller gain, while a longer-term investment may focus on annual returns. Percentage gain is useful because it lets you compare trades with different stock prices.
How does percentage change help compare trades?
Percentage change normalizes the result. A $5 move on a $25 stock is very different from a $5 move on a $500 stock, so percentage gain gives a cleaner comparison.
Does this calculator work for short trades?
It can still help compare price movement, but short trades profit when price falls. For short trades, interpret a negative price change as a favorable move before considering borrow costs, fees, and risk.
