Flexible and bullet structures

Standard term loans demand a fixed monthly payment, but some products are more flexible. A revolving credit facility lets you repay whenever you have surplus cash and redraw when you need it. A bullet or interest-only structure requires only interest during the term with the capital repaid as a lump at the end. Both suit businesses whose income arrives in irregular chunks — a project completion, a seasonal peak, a big invoice settling.

The cost of holding a balance

Flexibility is not free of interest. On any facility, interest accrues on the balance you are carrying, so a lump-sum approach where you hold a high balance for months costs more than steadily paying it down. The advantage is manageability, not cheapness: you avoid a fixed monthly demand during lean periods, at the cost of more interest if the balance stays high. On daily-interest facilities, repaying a lump the moment cash arrives immediately cuts the interest running.

Matching structure to income

If your income is genuinely lumpy — you complete projects and get paid in stages — a flexible or revolving facility you can overpay at will may fit far better than a rigid monthly loan. If your income is steady, a standard amortising loan is usually cheaper and simpler. Be realistic about your cash pattern rather than choosing flexibility you will pay a premium for and not use.

See planning repayments around cash flow, and for a line you can repay flexibly, explore a revolving facility.

Frequently asked questions

Is interest-only cheaper than a repayment loan?

Monthly, yes — paying only interest keeps the payment low. Overall, usually not: because you are not reducing the capital during the term, you carry the full balance the whole time and pay interest on all of it, then still owe the lump sum at the end. Interest-only helps cash flow now but tends to cost more in total and requires a solid plan to clear the capital.

Can I overpay a standard monthly loan with lump sums?

Often yes — many reducing-balance loans allow overpayments alongside the regular monthly amount, and an early lump-sum overpayment can save significant interest by cutting the balance sooner. Check for any early-repayment charge first, and confirm the product is reducing-balance rather than flat-rate, where overpaying may not reduce the total.
