Calculation assumptions

  • Default is assumed to have arisen; the conditions of BGB s. 286 are not checked here.
  • The base rate is an input: it is reset every six months under BGB s. 247 and changes faster than a tax scale.
  • Day-by-day calculation on a 365-day year — a disclosed simplification, as BGB s. 288 prescribes no interest convention.
