The Mathematics of the Daily Periodic Rate
Unlike most installment loans, card issuers charge interest daily on your average daily balance:
DPR = APR ÷ 365
Daily Interest = Average Daily Balance × DPR—
Balance Transfer & 0% APR Benchmark
A 0% intro balance transfer trades interest for an upfront fee. Compare the two over an 18-month promo:
A transfer only pays off if you clear the balance before the promo ends; any remaining balance reverts to the card's regular APR.
Why credit card interest is so costly
Credit cards typically carry among the highest interest rates of any common consumer debt, often 18-29% APR, compared to single-digit rates for many mortgages or auto loans. Interest also usually compounds daily, meaning balances can grow faster than borrowers expect if only minimum payments are made.
Because of this, credit card debt is generally considered a top priority to pay off aggressively before focusing on lower-interest debt or even some investing goals, since few guaranteed investment returns can outpace typical credit card APRs.

A worked example
A $3,000 balance at 22% APR with $120/month payments takes 34 months to pay off, with about $1,050 in total interest.
Raise the payment to $200/month instead, and payoff time drops to 18 months with about $540 in interest — roughly half the time and half the interest cost from an $80/month increase.
Balance transfer as an alternative strategy
Some credit cards offer promotional 0% APR balance transfer periods, which can dramatically reduce the total interest paid if you can pay off the balance within the promotional window — though transfer fees (often 3-5% of the balance) and the rate that applies after the promo period both need to be factored in.
Whether a balance transfer makes sense depends on the transfer fee versus the interest you'd otherwise pay, and your realistic ability to pay down the balance before the promotional rate expires.

Frequently asked questions
Should I pay more than the minimum?
Generally yes — paying only the minimum on a high-APR card can take many years and cost substantially more in interest than the original balance.
What is a good strategy for paying off credit card debt fast?
Paying more than the minimum, avoiding new charges while paying down the balance, and considering a balance transfer to a lower-rate card (if available) are all common strategies to accelerate payoff.
Does carrying a balance help my credit score?
No — this is a common misconception. Paying your balance in full each month (or keeping utilization low) is better for your credit score than carrying a balance, which only costs you interest.
Is a balance transfer worth it?
It can be, if the transfer fee is smaller than the interest you'd save and you have a realistic plan to pay off the balance before the promotional rate ends — otherwise the remaining balance often reverts to a high standard rate.
