Balance during fixed term
Notes & assumptions:
- Interest rate is assumed fixed for the selected fixed-term length, with no changes mid-term.
- For repayment, the base monthly payment is calculated over the full remaining term. Any monthly overpayment reduces the balance faster and may shorten the overall term.
- For interest-only, the scheduled payment is monthly interest; any overpayment reduces the balance.
- Fees: choosing Add to mortgage increases the borrowed amount; choosing Fees paid up front includes the fee in the totals but does not increase the balance.
- ERC (if applied) is simply added to the fixed-period total for comparison purposes.
- Reversion rate is used to estimate payments and totals after the fixed period for the remainder of the term.
- Results exclude valuation/legal costs and any future product changes after the fixed period.
