The Hidden Dangers of Late Payments

If you’re busy, it’s easy to forget a due date. But even one missed payment can:

Trigger steep late fees

Raise your APR without warning

Damage your credit score for up to six years (UK) or seven (US)


Real story: When Mark from Manchester forgot his HSBC payment by two days, his score dropped and his mortgage offer fell through.

Actionable Tips:

Set up autopay—even just for the minimum.

Add reminders to your phone’s calendar.

If you miss a payment, call your issuer ASAP.

Minimum Payments: A Debt Trap in Disguise

It may feel comfortable to pay the minimum on a tough month, but this creates long-term pain:

Interest racks up fast, often above 20%.

Your debt takes years, sometimes decades, to clear.

You end up paying much more than you borrowed.

How to Break Free:

Pay as much above the minimum as you can.

Prioritize high-interest cards.

Consider a 0% balance transfer.
