i = 0.1

n = 20

P = 1000

Fn = P \cdot {(1 + i)}^{n}

Pmt = \frac{i \cdot {(1 + i)}^{n} \cdot P}{{(1 + i)}^{n} - 1}

# Example 5 - Explicit set of assignment equations
# Future value and constant annual repayment
# Verified Solution: Fn=6727.5, Pmt=117.46

i=0.1 # interest rate
n=20 # no. of years
P=1000 # loan. amount
Fn=P*(1+i)^n # future value
Pmt=(i*(1+i)^n)*P/((1+i)^n-1) # annual repayment
