To calculate the lease payments we use the excel function PMT as in =PMT(rate,nper,pv,fv,type)
Rate = 11.2% Compounded monthly
Rate = 11.2%/12 (Monthly rate)
NPER = 24 months = 24
PV = 2650
FV =0
TYPE = 1 (Since the payments are due immediately meaning this is an annuity due)
So, monthly payment =PMT(11%/12,24,2650,0,1) = $122.39
Your monthly lease payments should be = $122.39
