Monthly loan payment on a $625,000 loan for 40 years with a 4.75% interest rate

Given:
Loan Amount: $625,000
Loan Terms: 40 years = 480 months = n  (convert years to months)
Interest Rate: 4.75% =
4.75/100
= 0.0475 = r  (convert percent to a decimal)
Monthly Loan Payment Formula:
Monthly Loan Payment =  
Loan Amount  * 
r / 12
/ 1 – ( 1+
r/12
 ) -n

Substitute given values into Monthly Payment Formula:
Monthly Loan Payment =  
625,000  * 
0.0475 / 12
/ 1 – ( 1+
0.0475/12
 ) -480

Monthly Loan Payment =  $2,910.99  ( rounded to two decimal places)
Notes:
Total Cost =  Monthly Loan Payment * Number of Payments
Total Cost =  $2,910.99 * 480 =  $1,397,275.20
Interest Cost =  Total Cost – Loan Amount
Interest Cost =  $1,397,275.20 – $625,000 =  $772,275.20
Interest Cost is greater than the Loan Amount
