Mortgage repayments formula? Does anyone no it?

Question

The question is i've borrowed $200000 at 14% interest per annum for 20yrs. How much do i have to repay each month??

Answer 1

You can just Google up an amortization chart and fill in the amounts.

Answer 2

p = iP/(1 - 1/(1 + i)^n)
i = 0.14/12
n = 12*20 = 240
p = (0.14/12)($200,000)/(1 - 1/(1 + 0.14/12)^240)
p = $2,487.041622
which the lender will probably round up to
$2,487.05
