The following formula is used to calculate the fixed monthly payment (P) required to fully amortize a loan of L dollars over a term of n weeks at an weekly interest rate of c. [If the quoted rate is 6%, for example, c is .06/52 or 0.0011538461]: P = L[c(1 + c)^n]/[(1 + c)^n - 1].
So,in this example we have:
P=3600[(0.00084615384(1+0.00084615384)^104]/[(1+0.00084615384)^104-1]
P=3600[0.00092395556]/[0.09194748944748435113000706288373]
P=$36.18/week
