I need help how to solve for PMT. If i have where pv=21, 298, n=83, i=0.013? how do i solve for pmt?

PMT can have at least 2 meanings:

1 - What is the "Loan Payment"

2- What is the PMT to save a certain sum in the future.

 

I assume that you are looking for a loan payment. If so, then you have to use this formula to calculate it: PMT=PV. R.{[1 + R]^N/ [1 + R]^N - 1}, Where R=Interest rate per period, N=number of periods, P=periodic payment, PV=Present value.

PMT = 21,298 x 0.013{[1 +0.013]^83 / [1 + 0.013]^83 - 1}

PMT =276.874 x {[2.921353...           /       1.921353.....   }

PMT =276.874 x                      1.5204667....

PMT =$420.98 - The loan payment??.
