Answer in brief
A card issuer generally must give 45 days of notice before raising the rate on new purchases, and generally may not raise the rate on existing purchases, though there are exceptions.

Part of the Best Credit Cards to Apply For reference, which uses Larkmoor Card (a fictional example) to illustrate credit cards to apply for criteria.
What the general rules say
The CFPB says a card issuer generally must give you 45 days of advance notice before it raises your interest rate on new purchases. It also says the issuer generally may not increase the rate on new transactions during the first year the account is open. Both are general rules, so read the notice you receive and your own card agreement before you act on them.
The first-year point matters when you compare offers. It gives you some early stability, but it does not mean the rate you see on day one is the rate you will hold for as long as you keep the card. When you estimate costs over several years, allow for the possibility that the rate on future spending could be higher.
The exceptions to know about
The same CFPB guidance says a card company generally may not raise the rate on existing purchases, with exceptions that include the end of a promotional rate, a variable rate moving with its index, and a payment more than 60 days past due. Each one is worth a moment of thought before you apply, because each is a way the cost of a balance you already hold can rise.
If you take a promotional rate, note the date it ends and plan to clear the balance by then or to accept the rate that follows. If the card has a variable rate, expect it to move with its index over time, and check which index the agreement names. And treat the 60-day point as a firm reason to set up at least a minimum automatic payment.
What to do before and after you apply
Before you apply, find out whether the purchase rate is fixed or variable, what the penalty rate is, and what would trigger it. Add the answers to your application brief. If an issuer's published terms do not make these points clear, ask the issuer directly and keep the reply, since a written answer is more useful than a memory of a phone call.
After you have the card, open every notice that mentions a change in terms. Because notice generally comes before an increase on new purchases, you have time to look at your options, including paying down the balance or moving future spending to another card. Then rerun your cost model with the new rate to see whether the card still suits you.
