Assumptions & sources

Assumptions

  • Fixed-rate convention: interest compounded semi-annually, not in advance.
  • Accelerated frequencies pay half (bi-weekly) or a quarter (weekly) of the monthly payment.
  • The rate is assumed constant for the whole amortization; in reality it resets at each renewal.
