The Deep Dive
To find Chuck’s monthly payment, we can use the formula for calculating monthly payments on an amortizing loan. The formula is:
Where:
-
is the total monthly payment. -
is the principal loan amount (the price of the Winnebago). -
is the monthly interest rate (annual interest rate divided by 12). -
is the number of payments (42 months).
To estimate Chuck’s monthly payment based on the conditions that his secured add-on interest needs to result in payments below
per month, we’ll assume an interest rate that permits this monthly payment.
Setting up the equation:
- Rearranging the equation
will yield the maximum for . - Without an exact interest rate, we can estimate considerable rates.
Using a sample calculation assuming no interest for simplicity (to get a methodology), we can derive that:
If we divide the total amount by the term, we can get an estimate for simplicity.
Since Chuck’s condition is to ensure the monthly payments are below
, we will need to ensure an interest rate adjustment to allow for it since a zero or low interest isn’t realistic.
Final Calculation
Let’s assume an interest rate around 4% per annum, or
:
You would typically continue this calculation iteratively until you find a rate that keeps
under
.
Given that exact interest rates weren’t provided, an expert’s adjustment would yield over time an effective monthly payment around
.
Thus rounding this we find
