The minimum payment trap: what paying the minimum really costs
Minimum payments are designed to keep a balance alive. Here is the arithmetic, and the three changes that end it fastest.

Paying the minimum is not a payment plan; it is a way of staying current while the balance barely moves. Understanding how the charge is calculated makes the escape route obvious.
How the minimum is built
A typical minimum is a small percentage of the balance plus the interest and fees charged that month. As the balance falls the minimum falls with it, which stretches the payoff out for years.
Most of an early minimum payment covers interest, not principal.
Interest is usually charged on the average daily balance, so mid-month payments help.
Carrying any balance normally removes the grace period on new purchases.
Three changes that shorten the timeline
Each one is small on its own; together they cut years off a balance without any extra income.
Fix the payment amount instead of letting it fall with the balance.
Pay twice a month to lower the average daily balance.
Call and ask for a lower rate, or move the balance to a 0% transfer if the fee is smaller than the interest saved.
Order matters when there are several cards
Pay every minimum, then send everything spare to one card. Highest rate first saves the most money; smallest balance first produces the first win sooner.
Avalanche — highest interest rate first — is mathematically cheapest.
Snowball — smallest balance first — is behaviourally easier for many people.
Either beats spreading extra payments evenly across every card.
Then protect the progress
A cleared card fills up again without a buffer behind it. A small emergency fund is what makes the payoff permanent.
Keep the cleared card open — closing it can shorten credit history and raise utilisation.
Hold one month of essentials in cash before chasing the last of the debt.
Set a utilisation ceiling of roughly 30% and stay under it.
