What Is a Mortgage?
A mortgage is a loan used to purchase real estate. Instead of paying the entire purchase price upfront, the borrower makes a down payment and borrows the remaining amount from a lender.
The mortgage is then repaid through regular payments over an agreed period. Each payment generally contains an amount toward the loan principal and an amount covering interest.
What Affects Your Mortgage Payment?
Your mortgage payment is mainly affected by the loan amount, interest rate and loan term. A larger loan or higher interest rate generally increases the required payment, while a longer loan term can reduce the regular payment but may result in more total interest.
Other housing expenses can also increase your total monthly cost. These may include property taxes, homeowners insurance, mortgage insurance and HOA or property fees.
How Does a Down Payment Affect Your Mortgage?
A down payment reduces the amount you need to borrow. For example, if a property costs 300,000 and you make a 60,000 down payment, the starting mortgage balance is approximately 240,000.
A larger down payment can reduce the amount of interest charged over the life of the loan because you begin with a smaller balance. Mortgage insurance requirements may also depend on the down payment and loan program.
How Do Extra Mortgage Payments Help?
Extra payments applied toward principal can reduce the outstanding mortgage balance faster. Because interest is generally calculated using the outstanding balance, reducing that balance sooner can potentially reduce total interest.
The actual benefit depends on your lender's terms and how additional payments are applied. Some loans may also have specific rules regarding extra principal payments.
What Is Mortgage Amortization?
Amortization is the process of paying a loan down over time through scheduled payments. An amortization schedule shows how much of each payment goes toward interest and how much reduces the principal.
With a typical fixed-rate mortgage, the balance gradually decreases throughout the loan term. The yearly schedule provided by this calculator gives you a simple overview of that process.
