Enter the rate in one direction
Enter the amount of base currency equal to one unit of the foreign transaction currency for both rates. The calculator multiplies the foreign amount by each rate, then subtracts the original base value from the later base value.
For €1,000 at an original rate of USD 1.08 per EUR and a later rate of USD 1.10 per EUR, the base values are $1,080 and $1,100, a positive difference of $20. A negative difference means the later base value is lower.
Illustrative comparison only
This comparison explains the arithmetic of a rate movement. It is illustrative and is not an accounting journal entry or a determination of realized or unrealized FX treatment.
Actual accounting can depend on the transaction, settlement, functional currency, dates, applicable policy and exchange-rate source.

How does this tool work?
- Enter the foreign-currency amount.
- Enter the original and later base-currency exchange rates.

Is this an accounting entry calculator?
No. It is a planning illustration of how the base-currency value changes between two rates. Accounting treatment depends on the transaction and your accounting policy.
Which way should the exchange rate be entered?
Use the amount of base currency equal to one unit of the transaction currency for both rates so the comparison is consistent.
