Pay 0% Interest On Your Spending

Credit cards which offer the same interest-free period on balance transfers and purchases are becoming harder to find. Here's how to avoid paying more interest on your spending than you should.

The market for credit card balance transfers is certainly a competitive one, so you'd think card companies would be doing everything they can to win your business. It`s surprising then that cards which charge 0% interest on balance transfers and purchases over the same period are becoming something of a rarity.Of all the 0% balance transfer cards which can be found in The Fool's independent Credit Card search, less than 40% offer interest-free periods on purchases which measure up. In my previous article `Are 0% Balance Transfers Still Going Strong?' I explained that the interest-free balance transfer period on some cards has been extended at the apparent sacrifice of equally attractive 0% deal on purchases. But you can still find some cards where the interest-free period runs for the same number of months on both. These are a sensible choice if you're planning to spend on your new card as well as transfer your balance from an old one. This means you won't inadvertently pay more interest than you should because `negative payment hierarchy' doesn't apply to this type of card. You may well have come across the term `negative payment hierarchy' before, but here's a quick recap: essentially this refers to the order in which different debts on your card are repaid. You could be forgiven for assuming that if you have a credit card which charges 0% on your balance transfer and the typical APR on your purchases, that your monthly repayment would be used to chip away at the most expensive debt first. But the vast majority of credit cards companies don't. And when I say `vast' I mean all but one!The rest use this neat little trick so your monthly repayments are actually used to pay off the cheapest debt - your 0% balance transfer - first. This means the more expensive debt - your purchases - stay on your card longer, costing you more interest while earning fat profits for the credit card company into the bargain. Hardly fair I think you'll agree.

The most competitive cards will still allow you to avoid paying interest on transferred balances and spending for a whole year, which can't be bad. But don't forget once the year has passed the higher APRs will take hold, which for the best cards will typically cost you around 14% to 16% in interest each year.
