Where,
P = Payment Amount
F = Future Amount
r = Rate of Interest (compounded)
N = Number of Payments
Rate of Interest Compounded is,
If Monthly, r = i / 1200
If Quarterly, r = i / 400
If Half yearly, r = i / 200
If Yearly, r = i / 100
F = c + [( amt * d ) / 100 ] and P = ( r * F ) / ( (1+r)-N - 1 )
Where,
amt = Desire amount range
d = Down payment
c = Closing Cost
P = Payment Amount
F = Future Value
r = Rate of Interest (compounded)
N = Number of Payments
Rate of Interest Compounded is,
If Monthly, r = i / 1200 and N = n * 12
If Quarterly, r = i / 400 and N = n * 4
If Half yearly, r = i / 200 and N = n * 2
If Yearly, r = i / 100 and N = n
ROI = ( (Earnings - Initial Invested Amount) / Initial Invested Amount ) x 100
The Return on Investment (ROI) is the ratio of the difference between earnings and the initial amount invested to the initial amount invested. ROI is often expressed in terms of percentage. Hence the value is finally multiplied by 100.
Where,
PV = Present Value
P = Annual Lease Payments
r = Interest Rate
n = Number of Years in the Lease Term
RV = Residual Value
SUM[P/(1+r)n] = The total amount paid over the lease term, discounted for the interest rate.
