What This Calculator Does
The Foreign Currency Price Comparison Calculator converts a price shown in a foreign currency into the equivalent amount in your home currency. Whether you are shopping abroad, browsing an international website, or reviewing a hotel bill, it instantly tells you what a sticker price really costs in money you understand.
How to Use It
Enter the price as it appears in the foreign currency, then enter the exchange rate expressed as the number of home-currency units you get for one unit of the foreign currency. For example, if 1 EUR = 1.08 USD, enter 1.08. The calculator multiplies the two values to give your home-currency price.
The Formula Explained
The math is a simple multiplication:
The exchange rate acts as a conversion factor. If the rate is greater than 1, the home currency is "weaker" and prices look larger; if it is less than 1, your home currency buys more.
Worked Example
Suppose a jacket is listed at €100 and the EUR→USD rate is 1.08. The home price is
