Loan or credit card
A credit card used within its interest-free period is one of the cheapest forms of credit available. The same card carrying a balance month to month is among the most expensive things a household can do. The gap between those two is entirely about whether you clear it.
Cards typically offer an interest-free period on purchases if the statement balance is settled in full. Used that way, the credit costs only the monthly card fee.
Carry a balance and interest applies, often on the full balance rather than the unpaid part, and the minimum payment is structured so the balance falls very slowly. A balance carried for years costs multiples of the purchase.
A loan has a fixed end date. For a defined cost you will not clear this month, that structure is worth more than the marginally lower rate a card might offer — because it removes the option of not finishing.
The honest test: have you cleared your card in full every month for the last six months? If yes, use the card. If no, the card will not behave differently this time.
