Why overpaying works on a reducing-balance loan

On a reducing-balance loan, interest is charged on what you still owe. Pay extra and the balance drops immediately, so every future interest charge is calculated on a smaller sum. The earlier you overpay, the more interest you skip, because there is more term left for that lower balance to save you money. An overpayment early in the term can save several times its own value in interest over a long loan.

Why it may not work on a flat-rate loan

On a flat-rate or factor-rate product, the total interest is fixed at outset on the original amount, not recalculated on a falling balance. Overpaying reduces the balance but not the total you were contracted to pay, so it may save little or nothing unless the agreement includes an explicit rebate. Always check which structure you have before assuming an overpayment helps. See why a flat rate differs from APR.

Watching for charges

Even on a reducing-balance loan, an early repayment charge can offset the interest saved. Some agreements allow a certain amount of overpayment each year free, then charge above that. Work out the net saving — interest avoided minus any charge — before overpaying a large sum. Where the saving is real, overpaying is one of the most efficient uses of surplus cash a business has.

Model an overpayment's effect on the repayment calculator, ask your lender for a revised balance, and see paying off a loan early.

Frequently asked questions

How much can I save by overpaying early?

It depends on the balance, rate and remaining term, but on a reducing-balance loan an early overpayment can save far more than its face value over a long term, because it removes interest that would otherwise accrue for years. The later in the term you overpay, the smaller the saving, since less interest remains to avoid. Run your figures through a calculator to see the exact effect.

Should I overpay the loan or keep the cash as a buffer?

It is a judgement between certainty and liquidity. Overpaying saves guaranteed interest but ties the money up. Keeping a cash buffer costs the interest you could have saved but protects you against a shock. For most businesses the answer is to hold a sensible buffer first, then overpay with genuine surplus above it — not to empty the account chasing interest savings.
