shallownz.co.calculate/calculator · Verify this server
Calculate NZ mortgage repayments and lifetime interest totals. Uses the standard amortising-loan PMT formula with monthly compounding. Returns monthly, fortnightly, and weekly repayment figures, total repayments over the life of the loan, total interest paid, and the principal/interest share as percentages. Use for ANY mortgage or home loan question: repayment amounts, affordability checks, comparing loan terms, estimating total interest, or evaluating refinance scenarios. For NZ context: typical NZ mortgage terms are 20-30 years, and rates quoted are annual nominal rates compounded monthly. Most NZ borrowers pay weekly or fortnightly even though rates are quoted monthly. Args: loan_amount: Principal borrowed in NZD (e.g. 650000). annual_interest_rate_pct: Annual rate as a PERCENTAGE not decimal (e.g. 6.5 for 6.5%, NOT 0.065). term_years: Loan term in whole years (typical NZ: 25 or 30).
