Why does my balance barely move at the start?

The reason it feels slow

On a reducing-balance loan, each level payment covers that month's interest first, then reduces the capital with whatever is left. Early on, the balance — and so the interest charge — is at its highest, leaving only a little to reduce the capital. That is why the balance barely seems to move in the first months. It is not an error; it is how amortisation works. See how the payment is built.

Why it speeds up

As you chip away at the capital, the balance falls, so the interest charge on each subsequent payment shrinks — which means more of each level payment goes to capital. The process accelerates: the balance drops faster and faster toward the end of the term. The slow start and quick finish are two ends of the same mechanism. Your amortisation schedule shows the crossover clearly.

Speeding it up yourself

If the slow early progress frustrates you, an overpayment — especially early — attacks the capital directly, cutting the balance before years of interest can accrue on it. That is exactly why early overpayments save so much. Check for any early repayment charge and that the product is reducing-balance first. On a flat-rate loan the concept doesn't apply, as the interest is fixed at outset.

See the balance fall on the repayment schedule, and if you'd like a shorter, cheaper structure, model it before you apply.

Frequently asked questions

Is it normal for the balance to fall slowly at first?

Yes, entirely — on a reducing-balance loan, early payments are mostly interest because the balance, and so the interest charge, is highest at the start. Little is left to reduce the capital, so the balance moves slowly. As the balance falls, more of each payment attacks the capital and it drops faster. The slow start is a feature of amortisation, not a mistake.

How can I make the balance fall faster?

Overpay against the capital, ideally early in the term. On a reducing-balance loan an overpayment reduces the balance directly, cutting the interest that would otherwise accrue on it for years — so early overpayments save the most and speed the balance down. Check for any early-repayment charge first, and confirm the product is reducing-balance rather than flat-rate, where overpaying may not help.
