You can afford a $300 per month car payment. You've found a 5 year loan at 8% interest.
What the maximum loan could be?
~~~~~~~~~~~~~~~~~~~

Use the formula for the monthly payment for a loan

    M = P%2A%28r%2F%281-%281%2Br%29%5E%28-n%29%29%29


where P is the loan amount; r = 0.03%2F12 is the interest rate per month;
n is the number of payments (same as the number of months); M is the monthly payment.


From this formula, the expression for the maximum loan is

    P = M%2F%28%28r%2F%281-%281%2Br%29%5E%28-n%29%29%29%29.


In this problem  M = $300;  r = 0.08%2F12,  n = 5*12 = 60 monthly payments.


Substitute these values into the formula and get for the maximim loan amount

    P = 300%2F%28%28%280.08%2F12%29%2F%281-%281%2B0.08%2F12%29%5E%28-60%29%29%29%29 = $14,795.53.


ANSWER.  The maximum loan amount is $14,795.53.

Solved.

Answer: $14,795.53

Explanation

Monthly payment formula
P = (L*i)/( 1-(1+i)^(-n) )
where,
P = monthly payment
L = loan amount
i = monthly interest rate in decimal form
n = number of months

We will plug in:
P = 300
i = 0.08/12 = 0.006666667 approximately
n = 60 (since 5 years = 5*12 = 60 months)

So,
P = (L*i)/( 1-(1+i)^(-n) )
300 = (L*0.006666667)/( 1-(1+0.006666667)^(-60) )
300 = L*0.020276394
L = 300/0.020276394
L = 14795.53021114
L = $14,795.53
Each decimal value is approximate.

Type 8 into the interest rate box, 5 into the year box, and 300 into the monthly payment box.
After entering those inputs, the "loan amount" box will go from empty to $14,795.53
