How the calculation works

Difference = second price − first price; percentage difference = difference ÷ first price × 100. A positive result means the second price is higher; a negative result means it is lower. The first price is the percentage reference. When it is zero, the amount is shown and the percentage is unavailable. A per-use or per-period average does not predict usage, renewal prices, cancellation terms or future charges. Only the entered period is compared. Choose one currency for every monetary input. The selector labels and formats amounts; it does not apply an exchange rate. Money displays use the selected currency’s standard minor units, including whole yen for JPY. Exact decimal arithmetic precedes rounding; halfway minor units round away from zero. Numeric input/result magnitudes are bounded by 9,007,199,254,740,991.

Example

Subscription example: Currency = GBP; First Price = 60; Second Price = 48. Result: -£12.00 (-20%).
