How Extra Money on Mortgage Works

When you make extra payments toward your mortgage, you reduce the principal balance faster, which lowers the total interest paid over the life of the loan. This can lead to significant savings and a shorter loan term.

Extra mortgage payments work by:

  • Reducing the principal balance more quickly, which decreases the amount of interest charged.
  • Shortening the loan term, which means you'll pay off the mortgage earlier.
  • Lowering your monthly payments, which can free up cash flow for other expenses.

Making extra payments is a strategic way to save money and pay off your mortgage faster, but it's important to consider your financial situation and goals before making additional payments.

The Formula Explained

The Extra Money on Mortgage Calculator uses the following formula to calculate the impact of extra payments:

New Monthly Payment = Current Monthly Payment + Extra Money per Month

Reduced Loan Term = Original Loan Term - (Extra Money per Month / New Monthly Payment) * Original Loan Term

Total Interest Savings = Original Total Interest - New Total Interest

Where:

  • Current Monthly Payment is your current mortgage payment.
  • Extra Money per Month is the additional amount you can put toward your mortgage.
  • Original Loan Term is the remaining term of your mortgage in years.
  • Original Total Interest is the total interest you would pay over the original loan term.
  • New Total Interest is the total interest you would pay with the extra payments.

Worked Example

Let's say you have a mortgage with the following details:

  • Current mortgage balance: $200,000
  • Current monthly payment: $1,200
  • Interest rate: 4.5%
  • Years remaining: 15
  • Extra money per month: $200

Using the calculator, you would find:

  • New monthly payment: $1,400
  • Reduced loan term: 12 years and 6 months
  • Total interest savings: $12,000

This example shows how making extra payments can significantly reduce your loan term and save you money on interest.
