keep existing car saves $22,608
get new car, saves $24,515
keep existing car saves $24,450
keep existing car saves $23,286
Present value of keeping existing car = present value of monthly payments
Present value of monthly payments is calculated using PMT function in Excel :
rate = 5% / 12 (converting annual rate into monthly rate)
nper = 120 (10 years with 12 monthly payments each year = 10 * 12 = 120)
pmt = -400 (monthly payment)
PV is calculated to be $37,713
Present value of new car = present value of monthly payments + immediate payment
Present value of monthly payments is calculated using PMT function in Excel :
rate = 5% / 12 (converting annual rate into monthly rate)
nper = 120 (10 years with 12 monthly payments each year = 10 * 12 = 120)
pmt = -350 (monthly payment)
PV is calculated to be $32,998
Present value of new car = $32,998 + $28,000 = $60,998
Amount saved by keeping existing car = $60,998 - $37,713 = $23,286
