Mortgage Payment Calculator
Key Takeaways
- A mortgage payment is typically made up of principal and interest, though property taxes, insurance, and PMI may also affect the total monthly payment.
- An amortization schedule shows how each mortgage payment is divided between principal, interest, and remaining loan balance over time.
- REI Grove's mortgage payment calculator uses inputs like purchase price, loan term, property taxes, and insurance to estimate your monthly payment.
- By using this mortgage payment and amortization calculator, buyers and investors can better estimate affordability, plan for payoff, and learn how mortgage costs change over the life of a loan.
Understanding Your Mortgage Payment and Amortization Schedule
Your mortgage payment consists of two key parts: principal and interest. Understanding how your monthly payments are attributed between them can help you plan for early payoff, choose the right time to refinance, and budget more effectively for yourself or your rental business.
In this article, we'll explore why understanding your mortgage payments through an amortization schedule is essential for financial planning, as well as how a tool like REI Grove's mortgage payment calculator can help. You can also review the CFPB's general mortgage resources for more background on how mortgage payments work.
What is a Mortgage Payment?
When purchasing a property, it's rare that buyers can afford to pay the entire cost of the home upfront. Instead, you'll take out a loan — a mortgage — to pay off the purchase over a fixed number of years (usually 15–30) with the property as collateral. Depending on the lender, the type of mortgage, the term of the loan, and the interest rate charged on the loan, you'll have a payment due each month.
Types of mortgages include fixed-rate (or traditional), where the interest rate and payments are the same over the life of the loan; adjustable-rate, where the rate may be lower initially and change periodically depending on market interest rates; interest-only, an uncommon mortgage type with a complex repayment plan usually involving a large balloon payment at the end; and reverse mortgages, made for older (62 and up) borrowers who can take out money in the equity of a home as a lump sum, line of credit, or fixed monthly payment that must be paid when a borrower dies, sells the home, or moves away permanently.
Your monthly mortgage payments can be visualized in a chart called an amortization schedule. This table lists each payment amount, as well as principal, interest, and the total balance, for the lifetime of your loan. This chart allows you to envision the breakdown of your loan over a long-term period to understand what your payments are contributing to. A mortgage calculator with amortization can help calculate these exact metrics for you.
Mortgage Payment Basics at a Glance
| Mortgage Component | What It Means | Why It Matters |
|---|---|---|
| Principal | The amount borrowed and repaid over time. | Paying down principal reduces the loan balance. |
| Interest | The cost of borrowing money from the lender. | Interest affects the total cost of the loan. |
| Loan term | The fixed number of years used to repay the loan. | Common terms include 15 and 30 years. |
| Property taxes | Local taxes based on the property's value. | Taxes can affect the total monthly housing cost. |
| Property insurance | Coverage for damage or loss related to the home. | Insurance may be required by the lender. |
| PMI | Private mortgage insurance, often required with less than 20% down. | PMI can increase the monthly payment until enough equity is reached. |
When to Calculate Your Mortgage Payment and Amortization Schedule
Whether you're a home buyer or investor, it's important to know upfront what your monthly mortgage payment will be so you can estimate how much house you can afford.
If you're in the market for a new property, use a mortgage payment calculator to assess a potential mortgage payment and gauge whether the amount is a number you're comfortable with. If it's doable, you can confidently move forward with a deal, and if the payments are too expensive, you can move on to another more affordable property.
Common Mortgage Types at a Glance
| Mortgage Type | How It Works | What to Consider |
|---|---|---|
| Fixed-rate mortgage | The interest rate and payments stay the same over the life of the loan. | Offers predictable monthly payments. |
| Adjustable-rate mortgage | The rate may start lower and change periodically based on market rates. | Payments may increase or decrease over time. |
| Interest-only mortgage | The borrower pays interest only for a period, often with a more complex repayment structure. | May involve a large balloon payment later. |
| Reverse mortgage | Older borrowers can access home equity as cash, a line of credit, or payments. | Usually applies to borrowers age 62 and up and must be repaid after certain events. |
How to Use the Mortgage Payment Calculator
Understanding your home payments is critical to making good financial decisions and being prepared to own a property. REI Grove's mortgage and amortization calculator is simple to use and provides you with several key outputs that put your future mortgage into perspective.
Let's discuss how the mortgage payment calculator works, including the necessary inputs as well as how to interpret its outputs.
Inputs
There are eight inputs needed to use the mortgage payment calculator:
- Purchase price
- Term
- Property taxes
- Property insurance
- Down payment
- Interest rate
- Private mortgage insurance (PMI)
- Start date
The purchase price is simply the price the seller has listed the home for. You can input the asking price or, if you think you'll be able to negotiate with the seller, a lower price you think is achievable.
The term refers to the term of the loan. The most common loan terms are 30 or sometimes 15 years, but they can range from 10 to 20 years as well. Though 10-year mortgages mean faster payoff, 30-year loans are standard because homebuyers can more easily afford smaller payments.
Property tax is a tax by a local government on a home based on its value. This amount will vary based on the area and the value of each home.
Property insurance is insurance that covers damage to your home from situations like weather-related events or theft of personal belongings.
Your down payment is an upfront payment on a house that is deducted from the cost of the purchase price, lowering the mortgage. The standard down payment on a property is 20%, but some buyers cannot afford a down payment that large.
Your interest rate will depend on the average market rate, your lender, your credit history, and your financial circumstances, along with other factors.
PMI, or private mortgage insurance, is often required if you put down less than 20% on a property. This insurance protects the lender in the event that you are unable to continue making payments on your mortgage. Once you reach 20% equity in the home, you'll usually be able to cancel this insurance. Learn more in our guide to PITI, PMI, and rate locks.
The start date is, as it sounds, the date when you'll own and begin paying your mortgage.
Outputs
After keying in your inputs, you'll be given six outputs:
- Monthly payment
- Loan amount
- Payment over 360 payments (30 years)
- Total interest
- Payoff date
- Monthly and yearly amortization
The monthly payment is the estimate of the amount you'll pay every month on your mortgage.
The loan amount is the amount you need to borrow after your down payment has been applied.
Payment over 360 payments is the total you'll have paid in principal and interest over the life of a 30-year loan.
Total interest refers to the amount overall that you will pay in interest depending on your interest rate and the term of your loan. This number is added on top of your principal to give you your payment over 360 payments.
The payoff date is the month and year you will completely pay off your mortgage. This number is calculated by adding the term of your loan to your start date.
The monthly and yearly amortization schedule takes all these outputs and charts them for a visual look at how much you'll have left on your mortgage at any given time. You can use this tool to see a breakdown of your principal and interest payments, as well as property tax, insurance, and PMI. You can also see your total balance at any point along the life of your loan.
Interpreting Your Results
You may input information about a home and find that its mortgage payments would be hundreds of dollars more than you can afford; alternatively, you may find that it's less expensive than you might have originally guessed. These numbers will allow you to assess if a home is in a good price range for you or if you need to adjust your search for a new property. They'll also help you feel prepared for what your mortgage will look like every step of the way.
Remember, however, that your debt service is not the only expense you'll incur as a homeowner. Be sure to factor in the cost of HOA fees (if you're in a HOA), upfront closing costs, and possible changes to your annual percentage rate if you don't have a fixed rate mortgage.
Conclusion
Understanding your mortgage amortization is key to tracking and paying off your loan successfully. With REI Grove's mortgage calculator amortization tool, you'll be better equipped to analyze your potential mortgage payment on a property and understand how to read an amortization schedule.
