Monthly payment formula:
A = P (r (1+r)^n) / ( (1+r)^n -1 )
eg.,
P = $10,000 (比如汽车贷款 10000刀)
r = 7.5% per year / 12 months = 0.625% per period (0.00625 on your calculator)
n = 5 years x 12 months = 60 total periods
10,000 (.00625 x (1.00625^60) / ((1.00625^60) - 1)
10,000 (.00625 x 1.45329) / (1.45329 - 1)
10,000 (.00908306 / .45329)
10,000 (.02003808) = $200.38
Monthly payment for car’s loan term would be $200.38.
如果只付利息的情况:
Loan payment = loan balance x (annual interest rate/12)
= 10000x 7.5%/12 = $62.50
