Intro & Guide
The mortgage calculator helps you turn a home price into a monthly payment you can actually plan around. Start with the purchase price, then add your down payment, term, rate, and escrow assumptions to see a clear estimate before you talk to a lender.
Use the full mortgage calculator to compare scenarios side by side. Adjust down payment and rate to understand how quickly the monthly number changes.
If you are evaluating buying versus waiting, the guide below shows how to separate the principal payment from taxes, insurance, and PMI so your planning stays realistic.
Features & Use Cases
Use the calculator to estimate a first-time purchase, a refinance, or a move-up home scenario. The layout keeps home price, down payment, rate, and term separate so each assumption is easy to review.
Add property taxes and homeowners insurance if you want a more realistic monthly payment. The tool can also show PMI when the down payment is under 20%, which is useful when comparing lower-cash-entry scenarios.
For teams or advisors, the breakdown makes it easier to explain the difference between the lender payment and the full housing cost.
Payment Scenarios & Workflow
Start with the purchase price, then choose either a percentage or fixed down payment. A larger down payment lowers the loan amount, reduces monthly interest, and can remove PMI.
Set the interest rate and loan term next. A shorter term usually means a higher monthly payment but much less total interest over time. That tradeoff is often the key decision in mortgage planning.

Educational Article
A mortgage payment is more than principal and interest. Property tax, insurance, and sometimes PMI can materially change what the loan feels like each month. That is why a realistic estimate matters before you commit to a home search.
The amortization schedule also matters. Early payments are interest-heavy, so rate changes affect your budget quickly. Compare scenarios with different terms to see how total interest and payment shape your decision.
If you plan to stay in the home for a long time, the total lifetime cost can be as important as the monthly figure. Use the estimate as a planning tool, not a final lender quote.
FAQs
Does the calculator include property tax and insurance?
Yes. You can include escrow estimates for property tax and homeowners insurance in the monthly payment.
How is PMI handled?
PMI is only applied when the down payment is below 20% and the PMI toggle is enabled.
Can I calculate a fixed-rate mortgage?
Yes. The calculator uses a standard amortization formula for fixed-rate loan estimates.
Does the tool save my numbers?
No. The mortgage estimate stays in your browser unless you copy the breakdown yourself.
Can I use it for refinancing?
Yes. Enter the refinance amount, term, and rate to estimate a new monthly payment.
Is this the same as a lender quote?
It is a planning tool. Final loan terms, fees, and underwriting outcomes can differ from lender quotes.
