Interactive Calculators: Repayment Calculator
This "any currency" calculator takes a loan amount (derived from the purchase
price and deposit) and calculates the monthly repayments over a set term or the
whole life of the mortgage. It also allows you to caculate the overall APR for the
loan and the Internal Rate of Return for the assumed life of the mortgage.
Both the Internal Rate of Return and the Annual Percentage Rate give an annual interest
rate which accurately reflects every payment made on the loan, including fees and
costs. The main difference between APR and the Internal Rate of Return, is that
APR is always measured over the full life of a loan term, whereas the Internal Rate
of Return allows you to compare the products over any length of time. This is more
suitable when you consider that the average life of a mortgage is only 6 or 7 years.
