How to Use a Mortgage Calculator for Your Home Loan
Estimating your monthly mortgage payment is simple. Follow the steps below based on the type of home loan you’re considering. These numbers are estimates and meant for planning purposes only.
Step 1: Enter the Home Price
Example: $500,000
Step 2: Choose Your Loan Type & Down Payment
Conventional Loan
First-time homebuyers: 3% down Min.
All other buyers: 5% down or more Min.
Step 3: Select Loan Term
30 years (most common option)
Step 4: Enter Your Interest Rate
Use the National Average Rate shown in the chart above
Your actual rate may vary based on credit, loan type, and market conditions
Step 5: Estimate Property Taxes & Insurance
Property Taxes (California):
Estimate 1.25% of the purchase price annually- Example: $6,250 per year on a $500,000 home
Homeowners Insurance:
If not in a fire-risk area, estimate $1,000 – $1,600 per year-Rural or high-risk areas may be higher
Step 6: Add Mortgage Insurance (If Required)
Conventional Loan
Mortgage insurance (PMI) applies if putting less than 20% down
PMI varies based on credit score and down payment amount. Use Grid above. Based on credit score and down payment.Example 5% down is 95% loan to value. You are getting 95% of the value in a loan and only 5% equity/down payment.
Important Note
Mortgage calculators are a great planning tool, but they don’t replace a full loan review. Final payments and qualification depend on your credit, income, debts, loan program, and the specific property.

What is a debt-to-income ratio?
A debt-to-income ratio is the percentage of gross monthly income that goes toward paying debts and is used by lenders to measure your ability to manage monthly payments and repay the money borrowed. There are two kinds of DTI ratios — front-end and back-end — which are typically shown as a percentage like 38/45. Sometimes go higher not to exceed 50%.
Front-end ratio is the percentage of income that goes toward your monthly mortgage costs, such as:
Mortgage principal and interest, Hazard insurance premium, Property taxes, Mortgage insurance premium (if applicable), Homeowner's association (HOA) dues (if applicable)
Back-end ratio is the percentage of income that goes toward paying all recurring, minimum monthly debt payments (on your credit report, court ordered or IRS), in addition to the monthly mortgage costs covered by the front-end ratio. Recurring monthly debt payments may include:
Credit card payments, Car loan payments, Student loan payments, Personal loan payments, Child support payments/Alimony payments
