- Interest compounds at the selected payment frequency.
- Repayments are made in arrears, at the end of each period.
- Interest-only repayments run for the selected period, then principal and interest is repaid over the remaining term.
- Values are rounded only after the full calculation.
- Upfront, monthly and annual fees are excluded.
