It is always better to charge a credit card in the local foreign currency, not USD. Choosing USD allows the merchant to apply a "Dynamic Currency Conversion" (DCC), which uses an inferior, inflated exchange rate, costing up to 15% more. Local currency ensures your bank or network (Visa/Mastercard) calculates the exchange rate.
Being charged in the local currency helps you avoid hidden ATM rip-offs by giving you the best possible exchange rate. This is because if you choose the local currency, your bank or card provider will do the currency conversion and apply the exchange rate.
The 2/3/4 rule is a guideline, primarily used by Bank of America, that limits how many new credit cards you can get: no more than 2 in 30 days, 3 in 12 months, and 4 in 24 months, helping to prevent over-application and manage hard inquiries on your credit report. While not universal, it's a useful benchmark for responsible card application, though other banks have different rules (like Chase's 5/24 rule).
When you travel to Canada, it is best to pay in local currency (CAD) instead of USD. We show you the top three benefits of paying with CAD. Find out how you can save money on your overseas trip and avoid unnecessary currency exchange fees. If you are planning to rely on USD in Canada, you may like to reconsider.
While it might sound like it's better to pay in pounds when you're abroad to avoid a non-sterling transaction fee, it's usually still cheaper to pay in the local currency. That's because when you choose to pay in the local currency, your card issuer will set the exchange rate.
If you plan to travel outside the country, you can save money by using a credit card that's accepted where you're traveling, doesn't charge foreign transaction fees and offers benefits for frequent travelers. For more travel tips and tricks, check out Bankrate's travel toolkit.
When using a credit card, remember the golden rule: only spend what you can afford to pay off in full each month. Carrying a balance leads to interest charges that can grow quickly. Paying off your statement balance each billing cycle keeps your costs down and your credit score in good shape.
What Is the 15/3 Rule?
Research shows that in most cases you can save by opting to spend in the local currency. For example, that would mean choosing sterling pounds in the UK or dollars in Canada. When you choose to pay in the currency of the region or country you're visiting, your credit card issuer will set the exchange rate.
Do Credit Cards Automatically Convert Currency? Yes, credit card companies automatically convert foreign currencies to the domestic currency using their exchange rate. When you look at your card statement, the amount charged will be in the domestic currency.
The benefits of paying in local currency
Your bank may charge a fee to carry out the transaction. The rate your card provider uses when processing local currency payments will, in most cases, be lower than that of the merchant, or foreign bank, when paying in dollars (USD).
The following steps will help you avoid foreign transaction fees:
Yes, using only 30% or less of your credit card's limit is a widely recommended guideline for maintaining a healthy credit score, but aiming even lower (under 10%) offers even better results, with experts suggesting single-digit utilization is ideal for excellent scores. The 30% rule is a good baseline to show lenders you're not overextending yourself, but the lower your balance relative to your limit, the more positively it impacts your credit, demonstrating responsible management.
$100 bills are legal tender, unlike some older notes that have been pulled from circulation. However, it is also legal in Canada for a merchant to refuse certain bills (while they can also choose to be “cash only.”) So, the point is, you could have a $100 bill and not be able to spend it anywhere in Canada.
Avoid airports and hotels; instead use local ATMs or online exchange services like Revolut. Exchange booths are another place to avoid – while often conveniently located, the rates are usually poor. You could find yourself paying fees and hefty commissions, too.
