Monthly loan payment on a $20,000 loan for 60 months with a 5.5% interest rate

Given:
Loan Amount: $20,000
Loan Terms: 60 months = n
Interest Rate: 5.5% =
5.5/100
= 0.055 = 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 =  
20,000  * 
0.055 / 12
/ 1 – ( 1+
0.055/12
 ) -60

Monthly Loan Payment =  $382.02  ( rounded to two decimal places)
Notes:
Total Cost =  Monthly Loan Payment * Number of Payments
Total Cost =  $382.02 * 60 =  $22,921.20
Interest Cost =  Total Cost – Loan Amount
Interest Cost =  $22,921.20 – $20,000 =  $2,921.20
