Monthly interest rate = Interest rate / 12
Monthly interest rate = 4.25% / 12
Monthly interest rate = 0.3542%
Monthly Payment = Principal * (Monthly interest rate / 1 - (1 + Monthly interest rate)-no of periods)
Monthly Payment = $180.576 * (0.3542% / 1 - (1 + 0.3542%)-240
Monthly Payment = $1118.19
Interest = Beginning principal * Monthly interest rate
Interest = $180,576 * 0.3542%
Interest = $478.65
Principal payment = Monthly Payment - Interest
Principal payment = $1118.19 - $478.65
Principal payment = $478.65
Ending Balance = Beginning Balance + Interest - Monthly payment
Ending Balance = $180,576 + $639.54 - $1118.19
Ending Balance = $180,097.35
