What it means
The debt only exists once you stop clearing the statement in full. From that point interest compounds monthly, meaning you pay interest on previously charged interest, and the balance grows on its own if payments are small.
Two features make credit card debt uniquely sticky. Rates are typically two to four times those on a secured loan because the lending is unsecured, and minimum payments are set at a low percentage of the balance, so most of each payment is absorbed by interest rather than reducing what you owe.
The practical consequence is a long, expensive repayment. A balance repaid at the minimum can take well over a decade to clear, and the total interest paid often approaches or exceeds the original amount borrowed.
For a small business, the risk goes beyond the cost. Card debt often sits on a director's personal card, mixing personal and business liability, and high card utilisation can pull down the credit score used to price a future business loan or lease.
Getting out has a small number of reliable moves. Pay well above the minimum, direct all spare cash at the highest-rate balance first while paying minimums elsewhere, consider a balance transfer or a fixed-term personal loan at a lower rate, and stop new spending on the card while the balance is being cleared, since fresh purchases usually lose their interest-free treatment anyway.
In practice
Real-world examples.
Example
A freelance photographer funds $9,000 of new equipment on a credit card intending to clear it in three months. A slow quarter stretches that to two years, and the interest paid roughly matches the cost of a lens she chose not to buy at the time.
Example
A cafe owner carries $20,000 across three cards. Consolidating into a three-year fixed-rate loan at 12% halves the monthly interest and, more importantly, gives a definite end date rather than an open-ended balance.
Example
A sales manager's company card accumulates $6,000 of unclaimed expenses because receipts were submitted late. The card is cleared once the claims are processed, but two months of interest at 22% is charged to the business in the meantime.
Formula
Calculation
Monthly interest = Balance x (Annual percentage rate / 12). Principal reduction = Payment - Monthly interest.
Take a $12,000 balance at a 24% annual percentage rate, so a 2% monthly rate. In the first month the interest is $12,000 x 0.02 = $240.
Paying $400 a month leaves $400 - $240 = $160 of principal reduction in month one. Repeating this month after month, the balance clears in 47 months, and the total paid is about $18,509, of which roughly $6,509 is interest.
Now raise the payment to $600 a month. Month one still charges $240 of interest, but $360 comes off the principal. The balance clears in 26 months, with total payments of about $15,478 and interest of roughly $3,478. Adding $200 a month therefore saves about $3,031 of interest and clears the debt 21 months sooner.Case study
Seen in the real world.
This is a fictional, illustrative case. Waverly Bakes, an invented three-site bakery, financed an oven repair and a seasonal stock build on the owner's credit cards, ending the winter with $12,000 outstanding at 24%.
The owner had been paying $400 a month, which felt responsible but implied 47 months of repayment and about $6,509 of interest. Working through the numbers with her accountant, she cut a monthly marketing spend of $200 that had never produced measurable bookings and redirected it to the card.
At $600 a month the debt cleared in 26 months for about $3,478 of interest, saving roughly $3,031. The illustrative point the accountant made was that no marketing campaign the bakery could realistically run offered a guaranteed 24% return, so repaying the card was the highest-return use of that $200.
Watch out
Common mistakes.
- Paying the minimum and assuming the debt is under control. The minimum is calculated to keep the account in order, not to clear it, and it leaves most of the balance untouched.
- Spreading extra payments evenly across several cards. Directing every spare dollar at the highest rate first, while paying minimums on the rest, always clears the total debt faster and cheaper.
- Doing a balance transfer and then continuing to spend on the cleared card. Many people end the promotional period owing more in total than when they started.
Questions
People also ask.
Does credit card debt hurt a business loan application?
It can, because high card utilisation and any missed payments feed into the credit scores that lenders and leasing companies use to price and approve facilities.
Is a balance transfer always a good idea?
Only if you can clear the balance within the promotional period and you factor in the transfer fee, which is commonly around 2% to 4% of the amount moved.
Should I repay card debt before building savings?
Generally yes for anything above a small emergency buffer, since a 24% interest cost avoided is a far better guaranteed return than any deposit account will pay.
