Bi-Weekly Bond Repayment Calculator

This calculator calculates the interest savings that result from making bond repayments on a bi-weekly basis instead of on a monthly basis. The assumption is that an additional monthly bond repayment of the same amount as the required bond monthly repayment is made and that the additional repayment is allocated against the outstanding capital balance only (no interest portion).

The home loan amortization is therefore not adjusted by recalculating the required bond amount after each additional bond repayment. The saving in interest is therefore significantly more than in a recalculation scenario.
