This calculator works out the percentage gain or loss between any two values, whether for a trade, an investment, or any other financial comparison.
Enter your starting and ending values, and the calculator returns the percentage change and absolute difference, a foundational concept covered in our guide on maximum drawdown.

Percentage gain measures relative change from the original value, going from R100 to R150 is a 50% gain, percentage points measure absolute difference between two percentages, the distinction matters and is a common source of confusion, especially in financial reporting.
Yes, if your ending value is higher than your starting value, the result shows as a positive percentage gain, if lower, it shows as a negative percentage loss, the same formula handles both directions automatically.
Because percentage changes are relative to a shifting base, losing 50% of R100 leaves R50, but gaining back to R100 from R50 requires a 100% gain, not 50%, this asymmetry is a fundamental, often underappreciated aspect of percentage-based returns.
Yes, the calculation is currency-agnostic, simply enter your starting and ending values in whatever currency or units you're working with, the percentage result will be accurate regardless of the specific currency involved.
Yes, this is the standard percentage return formula used broadly across finance, for annualised returns over multiple years accounting for compounding, use our dedicated CAGR Calculator instead.
