How it works

Interest-only payments look cheap because the balance never falls. The comparison below shows the repayment figure next to it so the trade-off is obvious.

Monthly interest = Balance × (Annual rate ÷ 100) ÷ 12

Example: 2,000,000 at 4% is 6,666.67 a month in interest, with the full 2,000,000 still owed at the end.

Questions people ask

When does interest-only make sense?

For short bridging periods, or for investors who plan to sell or refinance the asset. It needs a credible plan to clear the capital.

How much more does it cost overall?

A lot: you pay interest on the full balance for the whole term instead of a shrinking one, and still owe the original amount.

Can I overpay on an interest-only loan?

Often yes, and any overpayment reduces the balance and every future interest payment.
