20 Year Mortgage Rates Calculator



Understanding the financial implications of a 20-year mortgage is crucial for informed homeownership. The 20-Year Mortgage Rates Calculator serves as a valuable tool to help individuals assess their mortgage payments, interest rates, and overall financial commitment over the loan term.


The formula for calculating mortgage payments involves the principal loan amount, interest rate, and the number of monthly payments. The standard formula for a fixed-rate mortgage is:

Monthly Payment=Principal Loan Amount×Monthly Interest Rate1−(1+Monthly Interest Rate)−Number of Monthly Payments 

This formula takes into account the loan amount, annual interest rate, and the total number of payments over the loan term.

How to Use?

Using the 20-Year Mortgage Rates Calculator is a straightforward process:

  1. Enter Loan Amount: Input the principal loan amount, which is the total amount borrowed.
  2. Set Interest Rate: Specify the annual interest rate associated with the mortgage.
  3. Select Loan Term: Choose the loan term, in this case, 20 years.
  4. Calculate: Press the calculate button to obtain your monthly mortgage payment.


Consider an example:

  • Principal Loan Amount: $200,000
  • Annual Interest Rate: 4%
  • Loan Term: 20 years

Using the formula mentioned earlier:

Monthly Payment=$200,000×0.04/121−(1+0.04/12)−20×12

The calculated monthly payment would be the amount you need to budget for your mortgage.
