I went to the BMW USA website yesterday and reviewed the 2020 M4 lease offer example. I plugged BMW's numbers into my lease worksheet and calculated $898.60/month base payment (no sales tax) by using a money factor of .00145. BMW USA example shows $899/month for 36 mos. 30K miles.
Using the same BMW numbers and a money factor of .00165 the base monthly payment would increase to $920.53.
