Credit card churning, honestly

In short

I once watched a neighbor open four credit cards in a single spring, and he beamed like he had found a twenty dollar bill in an old coat. If you have been tempted by the same thing, here is the plain picture. Churning means opening cards to collect the sign up bonus, then moving on to the next one. The bonus can be worth real money, but only when the borrower pays every statement in full and on time. Each new application can lower a credit score for a while, and interest on a carried balance can erase the whole prize. Annual fees count against the reward, so add them up before you apply. Keep a simple record of every card, every deadline, and every spending target, because a missed one costs you the bonus.

The whole of it

What it is

A friend of mine calls churning a hobby, and I think that is fair. It is a hobby with paperwork. A person applies for a credit card that offers a bonus, such as points or cash back, after the cardholder spends a set amount in the first few months. When the bonus arrives, the person may close the card or keep it, and then applies for another. Do that again and again, and you are churning.

You have probably seen the ads. Spend $4,000 in three months and earn 60,000 points. At 1 cent a point, 60,000 points times $0.01 is $600, but the card company sets what points are worth when the cardholder redeems them, and that value changes from one program to the next. Some points turn into cash. Some turn into airline miles or hotel nights. Each has its own rules, and the issuer sets them.

Now, I do not look down on anyone who tries this. Wanting more for your money is a decent thing to want. But a bonus is not a gift. It is a payment the bank makes because it hopes to earn more from you over time, through fees, interest, and the swipe fees merchants pay. The whole thing works only when you outsmart that hope. Plan on it.

How it works

A few years back, I sat on a porch with a fellow who had done this for a decade. He told me the secret is boring. You use the card for bills you already pay, you hit the spending target, and you pay the balance in full. Nothing more.

Here is the machinery underneath. When you apply, the issuer pulls your credit report. That is called a hard inquiry, and it can lower your score a little for a time. A new account also lowers the average age of your accounts, which is another piece of how scores are figured. Your score can dip, then recover as you pay on time. Hold that thought, because it matters if you plan to borrow for a house or a car soon.

Issuers also set their own rules about who can earn a bonus. Some say you cannot earn it if you already hold that card, or held it recently. Some limit how many new cards they will approve in a set period. These rules are written in each card's terms, and they differ by issuer. The issuer can refuse the bonus or close the account if it decides a customer is gaming the system. Read the terms for each card before you apply.

Some cards charge an annual fee. If a card costs $95 a year and the bonus is worth $600, the net gain is $505. If you close the card before the fee posts, you may avoid it. But if the cardholder forgets, the fee lands, and the issuer expects payment for the year ahead.

The numbers, and where to find yours

I once helped a young woman sort her own papers, and she was surprised by how few numbers really mattered. Here they are.

First, your credit score. The Fair Isaac Corporation makes the best known scoring model, called FICO. Your bank or card issuer may show your score for free in its app. Second, your credit reports. Federal law gives you the right to a free copy of your report from each of the three nationwide credit bureaus, and the official place to get them is AnnualCreditReport.com. The Consumer Financial Protection Bureau explains how to read the report and dispute mistakes.

Third, the card's own terms. Every card has a document often called a Schumer box, which lists the interest rate, the annual fee, and other costs in a standard table. The CFPB keeps a database of card agreements you can search. For tax treatment, the Internal Revenue Service publishes guidance on how it views income, and the IRS website is the place that explains how card rewards are handled. Where a rule is set by law each year, such as a tax threshold, the figure is the current figure, which the official source publishes each year, and the site will show the verified number with its source and date.

A worked example

Let me tell you about a man named Daniel, a schoolteacher who earns $52,000 a year and wants to book a family trip. Daniel finds a card with a bonus of 60,000 points after $4,000 in spending within three months. The annual fee is $95. He values each point at 1 cent, so the bonus is worth 60,000 times $0.01, which is $600.

Daniel already spends about $1,400 a month on groceries, gas, and bills. Over three months that is 3 times $1,400, or $4,200. That clears the $4,000 target without buying one extra thing. Good.

Now the cost side. The annual fee is $95. So the net value of the first year is $600 minus $95, which is $505. Daniel pays the full balance each month, so he owes no interest.

Now look at the quiet cost. Suppose Daniel was planning to apply for a mortgage in four months. The hard inquiry might lower his score a few points, and the new account lowers the average age of his accounts. A lender may charge a higher rate for a lower score. If a score drop raised his rate by even a small amount on a $200,000 loan, the extra interest over many years could pass $505. That is the part the ads leave out. He decides to wait.

Daniel also keeps a short note. Card name, open date, spending target, deadline, and fee date. It takes five minutes. It saves him from a $95 surprise.

Where it goes wrong

I have seen good people trip on this, and it never felt like carelessness at the time. The biggest trap is carrying a balance. Say a borrower charges $4,000 to hit a target and then pays only part of it. Card interest can run high, and the card company discloses the rate in the terms. Take a rate of 24 percent a year as a round figure. Card companies often figure interest daily, so the real charge can differ. As a rough picture, 0.24 times $4,000 is $960 in interest over a full year. That is more than the $600 bonus. The prize turns into a loss.

Another trap is spending just to hit the target. If a person buys things they do not need to reach $4,000, the bonus is not a bonus at all. It is a discount on a mistake.

Missing a deadline is the third. The bonus often requires the spend within a set window. Miss it by a day and the points may not post.

There is also the matter of timing. A cluster of new accounts can make a lender cautious. If you plan to borrow soon, the quiet months before are not the time to open cards. Finally, watch the terms about closing a card. Closing an old account can shrink your total available credit, which can nudge your score the wrong way.

None of this means you are foolish for being curious. It means the hobby has edges, and a sensible person walks it with open eyes.

Questions to answer before you leave this page

Can you pay every statement in full, every month, without exception? Do you already spend enough on ordinary bills to reach the target without buying anything extra? Have you added up the annual fee and compared it with the bonus you honestly expect to receive? Are you planning to apply for a mortgage, a car loan, or any other big loan in the next several months, and would a small dip in your score matter? Have you read the issuer's terms on who can earn the bonus and when? Do you have a simple record of each card, its deadline, and its fee date? And if the whole thing feels like more work than it is worth, are you at peace with simply skipping it?
