Personal loan calculator FAQs

A personal loan is usually an unsecured loan repaid over a fixed term. You borrow a set amount, make regular repayments, and pay interest and any fees under your lender terms.

Data Sources & Methodology

LoanMetric estimates personal loan repayments with standard amortisation maths. Inputs are processed client-side and displayed with currency rounding to 2 decimals.

  • Personal loan scenarios are modelled as fixed-rate products by default.
  • Repayment frequency assumptions use 12 monthly, 26 fortnightly, and 52 weekly payments per year.
  • Base repayment uses the standard amortisation formula with periodic rate derived from annual rate.
  • Establishment fee is treated as upfront cost and added to total cost, not principal.
  • Monthly fees are pro-rated per repayment period for fortnightly and weekly scenarios.
  • Extra repayments are annualised first, then converted to equivalent amount per base repayment period.
  • Extra repayments can reduce total interest and may shorten overall payoff time, subject to lender product rules.
  • Estimated comparison-style rate, where shown, is explanatory only and not an official lender comparison-rate disclosure.

Some personal loans may limit extra repayments or apply early repayment / early payout fees. Check lender terms.
