Given:
Loan Amount: $250,000
Loan Terms: 30 years = 360 months = n (convert years to months)
Interest Rate: 6% =
Monthly Loan Payment Formula:

Substitute given values into Monthly Payment Formula:
Monthly Loan Payment =
Monthly Loan Payment = $1,498.88 ( rounded to two decimal places)
Notes:
Total Cost = Monthly Loan Payment * Number of Payments
Total Cost = $1,498.88 * 360 = $539,596.80
Interest Cost = Total Cost – Loan Amount
Interest Cost = $539,596.80 – $250,000 = $289,596.80
Interest Cost is greater than the Loan Amount
Loan Amount: $250,000
