Common Questions Answered

Quick help
Q1 What is a flat interest rate loan?
A flat interest rate scheme charges interest on the full original loan principal amount for the entire duration of the loan, completely ignoring any monthly repayments that lower the outstanding principal.
Q2 What is a reducing balance interest rate loan?
A reducing balance interest rate calculates interest charges only on the remaining outstanding principal amount of the loan. As you pay off the principal month by month, the monthly interest portion declines.
Q3 Which loan interest structure is cheaper to borrow?
A reducing balance rate is significantly cheaper than a flat rate of the same numerical percentage. This is because flat rate schemes charge you interest even on the portion of the loan you have already paid back.
Q4 How do I convert a flat interest rate to its reducing equivalent?
The reducing rate equivalent is typically 1.7 to 2.2 times higher than the nominal flat rate. For example, a loan advertised with a 10% flat interest rate is roughly equivalent to a reducing rate of ~18% in terms of total interest paid.
Q5 Are my compared loan amounts or rates sent to external servers?
Absolutely not. All rate conversion comparisons and compounding schedules are run locally within your browser sandbox. None of your data is sent to external databases or servers.
