Definition
A minimum repayment is the floor payment on a revolving facility or business credit card. Because interest accrues on the remaining balance, paying only the minimum leaves most of the balance in place, so interest keeps mounting and the debt clears slowly and expensively.
In plain terms
Paying the minimum is the slowest, dearest way out — most of your payment goes on interest, barely touching the debt.
Why it matters for your company
Pay more than the minimum whenever you can to cut the balance interest accrues on. See revolving facility interest and how to minimise interest on a revolving facility.

In practice
Picture a UK limited company using a revolving facility to smooth cash flow around supplier payments and customer receipts. When a quiet month hits, paying only the minimum feels like the safe choice — it keeps the facility open and avoids missing a payment. But because the outstanding balance barely moves, the next period's interest is calculated on almost the same amount as before, so the cost of carrying that balance persists rather than tapering off.
The more useful habit is treating the minimum as a floor, not a target. Whenever trading conditions allow, a director paying down more than the minimum shrinks the balance interest is charged against, which compounds in the company's favour over successive periods. See revolving facility interest for how that calculation works period to period.
Common pitfalls
The most frequent mistake is treating the minimum repayment as the expected or normal payment rather than a fallback for a genuinely tight month. Used that way month after month, a facility that was meant to flex with the business instead becomes a fixture on the balance sheet, with interest quietly eating into margin.
A related pitfall is losing sight of how the balance is actually moving. Because minimum payments are calculated to satisfy the facility terms rather than to reduce debt meaningfully, it is easy for a director to assume progress is being made when the balance is essentially static. Pairing minimum payments with a habit of reviewing the balance regularly — and reading up on how to minimise interest on a revolving credit facility — helps keep the facility working as intended, as a flexible tool rather than a drag on cash flow.
