A Mortgage Payment Is More Than Principal and Interest
Your loan payment is commonly described using principal and interest, but your actual monthly housing expense may also include property taxes, homeowners insurance, mortgage insurance and HOA fees.
Looking at both the monthly payment and the long-term amortization schedule provides a much clearer picture of what a mortgage may actually cost over time.

Frequently Asked Questions
What does a mortgage calculator calculate?
A comprehensive mortgage calculator can estimate principal, interest, property taxes, homeowners insurance, PMI, HOA fees and the total estimated monthly payment.
What is mortgage amortization?
Mortgage amortization is the gradual repayment of a loan through scheduled payments that are divided between interest and principal.
Why is more interest paid early in a mortgage?
Interest is generally calculated using the outstanding loan balance. Because the balance is highest early in the loan, a larger portion of early payments typically goes toward interest.
Can extra mortgage payments save interest?
Yes. Applying additional money toward principal can reduce the outstanding balance sooner, which may reduce future interest and shorten the repayment term.
How does a biweekly mortgage payment strategy work?
A common biweekly strategy involves making half of the normal monthly payment every two weeks. Twenty-six half-payments equal roughly thirteen full monthly payments per year.
Which mortgage calculator should I use first?
Start with the Mortgage Calculator to establish your monthly payment. Then use the Amortization and Mortgage Interest calculators to understand the long-term cost before testing additional-payment strategies.
