Specify your down payment as either:
- Dollar amount (e.g., $80,000)
- Percentage (e.g., 20%)
The calculator determines your loan amount automatically.
Step 5: Enter Interest Rate
Input the annual interest rate as a percentage (e.g., 6.5 for 6.5% APR).
Step 6: Select Loan Term
Choose your loan term:
- 15 years (higher monthly payment, less interest)
- 30 years (lower monthly payment, more interest)
- Other terms if available
Step 7: Add Additional Costs (Optional)
Some calculators allow you to include:
- Annual property taxes

- Amortization schedule (if available)
Step 9: Compare Scenarios
Test different scenarios:
- Different home prices

- Different loan terms
Step 10: Assess Affordability
Compare calculated payments to your monthly budget to determine affordability.

Frequently Asked Questions
Q: Are free mortgage calculators accurate?
A: Free mortgage calculators are highly accurate when provided with correct inputs, using the same formulas lenders use. However, actual loan terms may include additional fees (origination, closing costs) not included in basic calculations. Use calculator results as estimates and get pre-approved by lenders for precise rates and terms.
Q: What information do I need to use a mortgage calculator?
A: You need four main pieces of information: home purchase price, down payment amount (or percentage), annual interest rate (APR), and loan term (years). Optional information includes annual property taxes, homeowners insurance, and PMI if applicable. Some calculators estimate taxes and insurance if you don't have exact figures.
Q: How does down payment affect my mortgage payment?
A: Larger down payments reduce both monthly payments and total interest paid. A 20% down payment eliminates PMI, further reducing monthly costs. For example, on a $400,000 home, 20% down ($80,000) vs. 10% down ($40,000) saves approximately $255 per month and over $50,000 in total interest over 30 years.
Q: Should I use a 15-year or 30-year mortgage?
A: 15-year mortgages have higher monthly payments but significantly less total interest, while 30-year mortgages have lower monthly payments but more total interest. Choose based on your budget and goals: 15-year if you can afford higher payments and want to save on interest, 30-year if you need lower monthly payments for cash flow flexibility.
Q: How accurate are interest rate estimates in calculators?
A: Interest rate estimates in calculators are based on current market rates, but your actual rate depends on credit score, debt-to-income ratio, loan type, and lender. Use current market rates as starting points, but get pre-approved by lenders for accurate rates. Rates can change daily, so calculator results are estimates based on the rates you enter.
Q: Can I use a mortgage calculator to determine how much house I can afford?
A: Yes, work backwards: determine your maximum comfortable monthly payment, then use the calculator to find home prices that result in that payment with different down payment and interest rate scenarios. Most experts recommend keeping total housing costs (PITI) below 28% of gross monthly income for affordability.
