Rev. Rul. 2002-62 lists three methods you may use in determining what are substantially equal periodic payments:

2.the amortization method, and
3.the annuitization method.
All three methods require the use of a life expectancy or mortality table. The second and third methods require you to specify an acceptable interest rate.
