Excel Bond Calculator Template

In most instances, the calculations on a bond statement do not agree to the calculations on an amortization table. This is mainly because most financial institutions calculate interest on a daily basis and only capitalize interest on a monthly basis. Monthly bond repayments are also not always deducted on the last day of each month and most amortization tables do not provide for ad hoc bond repayments. If you therefore want to review the calculations on a bond statement, it could be quite a complicated exercise. The Excel Skills web site provides a unique and innovative Excel based Loan Calculation template that can be used for this exact purpose and the template also includes a comprehensive forecasting feature that can be used to calculate interest savings resulting from ad hoc bond repayments.

In addition, a free bond calculation template is also available and includes:

calculating a monthly bond repayment amount, total interest and total bond repayment amount
comprehensive calculation of monthly net disposable income
maximum bond amount and minimum income requirement based on net disposable income
interest savings resulting from increased monthly bond repayments
interest rate sensitivity measuring the effect of two different interest rates on bond repayments
a capital repayment chart that displays the timing of capital redemption over the bond period
an interest saving chart that displays increased installment savings over the bond term

Bond Calculator Objectives

The main objectives in using bond calculators should be the calculation of bond repayments & interest, determining levels of affordability, calculating the income qualification standard associated with a required bond amount and analyzing optimal repayment options.

All of these objectives can be met by using our bond calculators. We also provide additional bond calculators which enable the user to calculate sensitivities around the main bond variables - interest rates, bond periods and deposit amounts.

A transfer and bond cost calculator is provided to assist with estimating initial bond and transfer costs. Detailed transfer duty and bond registration cost tables are also available from this calculator.

Many bond affordability calculators still use the assumption of basing the net disposable income on a fixed percentage of 30% of gross income. Our maximum bond amount calculator includes a comprehensive calculation of net disposable income as required by the National Credit Act.
