Bond Calculators 
Monthly
Bond Repayments 
This bond calculator enables users to
calculate the monthly bond repayment that is required based
on a user defined bond amount (property purchase price less
deposit amount), annual interest rate percentage and a bond
period in years. The calculated results also include the total
bond repayments over the entire bond period, the total interest
that is incurred over the entire bond period as well as the
monthly bond repayments based on a 15 and 30 year bond period
and annual interest rates that are 1% more and 1% less than
the specified bond interest rate. 
Bond
Affordability 
This bond calculator enables users to
calculate an estimated bond qualification amount based on
what they can afford. Bond affordability is determined by
the estimated monthly net disposable income (as required by
the National Credit Act) which is defined by specifying a
monthly combined gross remuneration amount and income from
other sources less total salary deductions, total monthly
expenses and monthly finance costs. Note that if the net disposable
income that is calculated is more than 30% of the total gross
remuneration, the bond qualification amount is based on a
30% repayment to income ratio (as applied by most financial
institutions). The annual bond interest rate and bond period
also affect the calculation of the bond qualification amount
and the calculator includes an interest rate buffer percentage
which is used to measure the sensitivity of the bond affordability
calculation to interest rate changes. 
Minimum
Net Disposable Income 
This bond calculator enables users to
calculate the minimum monthly net disposable income that is
required in order to qualify for a user defined bond amount.
The calculation is based on the bond amount (property purchase
price less deposit amount), annual bond interest rate and
bond period that are specified by the user. A net disposable
income percentage can also be entered in order to calculate
the required gross monthly income amount. The minimum net
disposable income that is calculated is based on the required
monthly bond repayment. 
Increased
Instalment 
This bond calculator enables users to
calculate the amount of interest that can be saved by increasing
the monthly required bond repayment by a user defined additional
repayment amount. The calculation is based on the bond amount
(property purchase price less deposit amount), annual bond
interest rate, bond period and the additional payment amount.
An average annual inflation rate can also be specified in
order to calculate the present value of the interest saving.
The calculated results include the adjusted bond period in
months and years, the total bond repayments and interest over
the original and adjusted bond periods and the interest savings
amount and present value. 
Amortisation
Table 
The bond amortisation table enables users
to view a comprehensive analysis of bond repayments, interest
charges, capital repayments and outstanding bond balances
over the entire bond period. The table is calculated based
on the bond amount (property purchase price less deposit amount),
annual bond interest rate and bond period that is specified
by the user and includes the monthly bond repayments, interest
charges, capital repayments and outstanding bond balances.
The percentage capital that is outstanding after each monthly
bond repayment is also included in a separate column and indicates
how the outstanding capital amount is reduced over the bond
period. 
Transfer
& Bond Costs 
This calculator enables users to calculate
an accurate estimate of the transfer & bond costs that
will be incurred when buying a property. The calculation is
based on the property purchase price and bond amount (property
purchase price less deposit amount) which is specified by
the user and includes transfer duties, transfer fees, deed
office levies, bond registration fees and other transfer &
bond related costs. Note that the transfer & bond registration
costs that are calculated should be seen as estimates only
 actual charges may therefore differ from these estimates. 
BiWeekly
Bond Repayments 
This bond calculator enables users to
calculate the interest savings that result from making biweekly
bond repayments instead of monthly bond repayments. The calculation
is based on the bond amount (property purchase price less
deposit amount), annual bond interest rate and bond period
that is specified by the user and indicates the total bond
repayments and total interest over the original and adjusted
bond periods as well as the total interest savings. For the
purpose of the calculation, it is assumed that the original
required bond repayment amount remains unchanged and that
the additional biweekly bond repayment is allocated against
the outstanding capital balance of the bond.
