John purchase an apartment for R180000.00 with a down payment of R45000.00. John secure a mortgage bond with a bank for the balance at 18% per annum compounded monthly with a term Of 20 years. What are the monthly payments?

using the calculator at https://www.algebra.com/tutors/faq.mpl, make the following inputs.
pv = 180000 minus 45000 = 135000
fv = 0
np = 20 * 12 = 240
ir = 18/12 = 1.5
payment at end
click on pmt to get the answer of -2083.47
that means that the payment is 2083.47 payable at the end of each month for 240 months.
since the interest rate is 18% per year, compounded monthly, you divide the annual interest rate per year by 12 to get the monthly interest rate.
since the payments are at the end of each momnth, you multiply the number of years by 12 to get the number of months.
here's what the results look like.
