Mortgage Calculator
| Year | Interest | Principal | Balance |

Choosing a mortgage is likely the biggest financial decision of your life. Most homebuyers make the mistake of shopping for the lowest Interest Rate, but savvy investors shop for the lowest APR.
If you want to avoid hidden bank fees and understand exactly what your home loan costs, you need to look beneath the surface. Our Mortgage APR Calculator is designed to give you the transparency you deserve.
What is Mortgage APR? (The Real Cost of Borrowing)
While the “Interest Rate” is the percentage a lender charges you for the principal amount, the APR (Annual Percentage Rate) reflects the total cost of the loan.
The APR includes:
- The Base Interest Rate
- Mortgage Broker Fees
- Loan Origination Fees
- Discount Points (prepaid interest)
- Mortgage Insurance (PMI)
Pro Tip: If Lender A offers a 6% interest rate with $5,000 in fees and Lender B offers a 6.2% rate with $0 fees, Lender B might actually be cheaper. The APR calculator helps you see this instantly.
Why APR Matters More Than Interest Rates
In the mortgage world, “Interest Rate” is marketing; “APR” is reality. Under the Truth in Lending Act (TILA), lenders are legally required to show you the APR so you can compare different loan offers on a level playing field.

How to Use the Mortgage APR Calculator
Our tool is built for accuracy and speed. To get the best results, have your Loan Estimate document ready and input the following:
| Mortgage Term | What it Means | Impact on Your APR |
|---|---|---|
| Home Price | The total purchase price of the property. | Higher prices lead to larger loans and higher total interest. |
| Down Payment | The cash you are paying upfront. | A higher down payment reduces risk and can lower your APR. |
| Loan Term | Usually 15 or 30 years. | Shorter terms (15y) have lower APRs but higher monthly payments. |
| Interest Rate | The base rate quoted by your bank. | This is the “engine” of your APR; it dictates the monthly cost. |
Understanding “Points” and Their Impact on APR
Mortgage points (or discount points) allow you to “buy down” your interest rate.
- 1 Point = 1% of your loan amount.
- Paying points increases your upfront costs but lowers your monthly interest rate.
Our calculator will show you how these points affect your APR. If you plan on staying in your home for 10+ years, paying points to lower your APR is often a brilliant financial move.
Factors That Influence Your Mortgage APR
