By making extra payments toward your loan, you can significantly shorten the repayment term and save thousands of dollars in interest. The Extra Payments Mortgage Calculator is designed to show you exactly how much faster you can pay off your mortgage and how much money you’ll save.

Practical Example

Loan details:

• Mortgage: $250,000
• Interest rate: 5%
• Term: 30 years
• Standard monthly payment: ≈ $1,342

Scenario A – No extra payments:

• Payoff time: 30 years
• Interest paid: ≈ $233,139

Scenario B – $150 extra per month:

• New payoff time: ≈ 25 years
• Interest paid: ≈ $189,000
• Interest savings: ≈ $44,000

👉 Just $150 extra per month saves almost $44,000 and cuts 5 years off the loan.

Tips for Making Extra Mortgage Payments
