Line of credit
Revolving credit you can draw from as needed, paying interest only on the amount you actually use.
Unlike a fixed-amount loan, a line of credit gives you access to a limit that you can use, repay, and reuse as you wish. Interest applies only to the balance you have borrowed, not to the full limit available.
This flexibility suits variable or unexpected expenses well. The rate is often variable, and it takes discipline to make regular repayments so the balance does not build up over time. It is often an affordable option for debt consolidation.
