Repayment Mortgage Calculator Mortgage required: * Term of Mortgage, in years: * Interest rate: * Enter 6% as 6. Maximum acceptable cost: * Enter £750pm as 750. Calculator Notes For mathematical purity the interest is calculated on the basis of the twelfth root of the rate selected, and the outstanding capital recalculated each month. In practice mortgage maths is different in detail and so do not expect these figures to match those of any quote. It does not include any insurance or other costs and these aspects will mean that the total cost on any real mortgage will be higher. Your property may be repossessed if you do not keep up repayments on your mortgage. The figures calculated are purely a guide and cannot be guaranteed.
