How do you solve exchange rate questions? ›

Rule #1 says to "Keep track of your currency units." It is important because foreign exchange prices have a currency in both the numerator and the denominator. Most prices (for instance, a $15,000/car price on a new car) have a non-currency asset in the denominator and a currency in the numerator.

In most countries, there are no legal limits on currency exchange.

Calculate an FX rate using this simple formula: Your starting figure (in your local currency) divided by the final number (in the new foreign currency) = the exchange rate.

Divide your current (home) currency by the exchange rate. For example, suppose that the USD/EUR exchange rate is 0.631 and you'd like to convert 100 USD into EUR. To do this, simply multiply the 100 by 0.631 and the result is the number of EUR that you'll receive: 63.10 EUR.

It is easy to confuse whether you need to multiply or divide by the exchange rate. One way to remember is with the rule: If you are going from the “1” to the other currency then multiply. If you are going to the “1” from the other currency then divide.

If you are traveling on an international flight and have $10,000 or more in your possession, you must disclose the amount of U.S. Currency in your possession on a FinCEN 105 form. Those disclosure rules do not apply on a domestic flight.

You'll get the best rates when you exchange currency during bank hours. The worst time to exchange is on the weekends because markets around the world are closed. Why is this a problem?

There is no maximum limit, however, any amount exceeding $10,000 USD must be declared upon arrival on both the Form 6059B and FinCEN 105. All forms must be filled in completely and truthfully. The penalties for inaccurate declaration and non-compliance can be severe including heavy fines and/or confiscation of funds.

The exchange rate gives the relative value of one currency against another currency. An exchange rate GBP/USD of two, for example, indicates that one pound will buy two U.S. dollars. The U.S. dollar is the most commonly used reference currency, which means other currencies are usually quoted against the U.S. dollar.

How exchange rates are calculated? ›

Current international exchange rates are determined by a managed floating exchange rate. A managed floating exchange rate means that each currency's value is affected by the economic actions of its government or central bank.

The core equation is RER = eP*/P, where, in our example, e is the nominal dollar/euro exchange rate, P* is the average price of a good in the euro area, and P is the average price of the good in the United States.

If you don't know the exchange rate, you can use this formula: starting amount (base currency) / ending amount (foreign currency) = exchange rate. Use the currency conversion formulas mentioned earlier to calculate how much you'd get for your currency if you were trading in the forex market.

The core equation is RER = eP*/P, where, in our example, e is the nominal dollar/euro exchange rate, P* is the average price of a good in the euro area, and P is the average price of the good in the United States.

The equation of exchange can be written MV = PY. When M, V, P, and Y are changing, then %ΔM + %ΔV = %ΔP + %ΔY, where Δ means “change in.” In the long run, V is constant, so %ΔV = 0. Furthermore, in the long run Y tends toward Y _P, so %ΔM = %ΔP.
