How to use this calculator
Adjust the inputs to your own scenario, then review the result alongside the assumptions below. The $ symbol is a currency label; the tool does not convert exchange rates.
Worked example
A move from $100 to $110 is +$10, or +10%.
The formula
Percentage change = (ending price ÷ starting price − 1) × 100.
What the result means
Compare the output with the stated assumptions. Changing an input changes the arithmetic; it does not establish how a real trade or investment will perform.
Assumptions and limitations
Price change only; excludes dividends, splits, currency changes, and costs.
