Is the 1.9% annually or monthly?

OpenStudy (anonymous):

monthly

OpenStudy (wolf1728):

payment = .019 + .019/(((1.019)^36)-1) * principal payment = .019 + (.019 / .9691129313) * principal payment = .019 + 332.5690841496 payment = 332.59 Using a payment calculator I get 485.12 So I made a math mistake.

Well okay - I'm still searching for my error.

OpenStudy (wolf1728):

payment = .019 + (.019 / .9691129313) * principal Should be payment = (.019 + (.019 / .9691129313)) * principal Maybe it's there.

r083rt I went to that online calculator again- I made mistake by inputting the monthly interest instead of the annual interest. When I input 22.8 ANNUAL interest I get: $654.87 you did quite well !!!
