Buying a home is one of the biggest financial commitments most people make. A mortgage is typically a long-term loan, often lasting 15 to 30 years. While monthly mortgage payments can feel manageable, the total interest paid over the loan’s lifetime can be overwhelming. That’s where a Paying Extra on Mortgage Calculator becomes a powerful tool.
Paying Extra On Mortgage Calculator
How to Use the Paying Extra on Mortgage Calculator
Using the calculator is simple and requires just a few details about your loan:
- Enter the loan amount – This is the total balance of your mortgage.
- Input the interest rate – Provide your annual mortgage interest rate (for example, 5%).
- Select loan term – Indicate the original term length (e.g., 30 years).
- Enter your monthly payment – Your standard scheduled mortgage payment.
- Add extra payment amount – Enter the amount you plan to pay in addition to your regular payment, either monthly or annually.
- Click Calculate – The calculator will display how much time and money you’ll save on interest payments.
Formula Behind the Calculator
The general mortgage payment formula is:
M = P [ r(1 + r)^n ] / [ (1 + r)^n – 1 ]
Where:
- M = Monthly mortgage payment
- P = Loan amount (principal)
- r = Monthly interest rate (annual rate ÷ 12)
- n = Total number of payments (loan term in months)
When you pay extra, the additional amount goes directly toward the principal balance. This reduces the outstanding loan faster, which in turn lowers the amount of interest charged.
For example:
If you owe $250,000 at 5% interest on a 30-year loan, your monthly payment is about $1,342. If you add $200 extra each month, you could save over $60,000 in interest and pay off your mortgage nearly 6 years earlier.
Examples of Extra Payments
Example 1: Small Monthly Extra
- Loan: $200,000
- Rate: 4%
- Term: 30 years
- Regular Payment: $955
- Extra Payment: $100/month
Result: Pay off in about 25 years instead of 30, saving over $30,000 in interest.
Example 2: One-Time Lump Sum Payment
- Loan: $300,000
- Rate: 5%
- Term: 30 years
- Regular Payment: $1,610
- Extra Payment: $20,000 one-time after year 5
Result: Saves around $50,000 in interest and reduces the loan term by almost 3 years.
Example 3: Biweekly Payments
- Loan: $250,000
- Rate: 5%
- Term: 30 years
- Regular Payment: $1,342/month
- Biweekly Payment: $671 every two weeks (instead of monthly)
Result: By making 26 half-payments (13 full payments annually), you pay off your mortgage about 5 years earlier.
