Estimated Monthly Payment
What Is a Loan Calculator?
A loan calculator is an online tool that estimates your monthly payments, total interest, and overall cost for a given loan. By entering key loan details, you can see how much you will owe each month and plan your budget accordingly.
This calculator is particularly useful for:
- Homebuyers planning their mortgage
- Real estate investors analyzing investment properties
- Anyone considering refinancing
By using the Zillow Loan Calculator, you gain insight into your long-term financial commitment without guesswork.
Key Inputs for the Zillow Loan Calculator
To get accurate estimates, you’ll need three pieces of information:
- Loan Amount ($) – The total money you plan to borrow.
- Example: $300,000 for a home purchase
- Interest Rate (%) – Annual interest rate charged by the lender.
- Example: 6.5%
- Loan Term (Years) – The length of the loan repayment period.
- Example: 30 years
Once these numbers are entered, the calculator uses a standard amortization formula to compute your monthly mortgage payments.
How to Use the Zillow Loan Calculator
Step 1: Enter the Loan Amount
Input the total amount you plan to borrow. This is typically the home price minus your down payment.
Step 2: Input the Interest Rate
Add your expected annual interest rate. This can be fixed or variable, but ensure the rate matches your loan type.
Step 3: Enter the Loan Term
Choose the duration of your mortgage, typically 15, 20, or 30 years.
Step 4: Click “Calculate”
The calculator instantly generates your estimated monthly payment, including principal and interest.
Step 5: Optional Actions
- Copy Results: Save your results to clipboard for personal reference.

Example Calculation
Suppose you want to buy a home with:
- Loan Amount: $350,000
- Interest Rate: 5%
- Loan Term: 30 years
The calculator computes:
- Monthly interest rate = 5% ÷ 12 = 0.004167
- Total payments = 30 × 12 = 360 months
- Monthly payment = 1−(1+0.004167)−360350,000×0.004167
Estimated Monthly Payment: $1,878.88
This allows you to see if the mortgage fits your budget before applying.
