How this is calculated
The purchase price is the loan amount, with no deposit. Interest stays at the chosen annual rate, divided by 12 and charged monthly on the opening balance. Fees, insurance and transfer costs are excluded.
The regular instalment stays fixed. Extra monthly payments stack and continue until the bond is settled. Once-off payments happen in the first repayment month of the selected loan year, after that month's interest. Year 5 means month 49, not five completed years.
Amounts and monthly interest are rounded to cents. The final payment is capped at the balance owed. Any cent-rounding residue is settled at the original maturity. Payments scheduled after payoff are ignored.
Total repayment includes the principal, interest and all extra payments actually made. Total saved is the reduction in interest, so extra payments are already accounted for. This is a planning estimate; a lender using daily interest may produce different amounts.
