Step 1 of 6

Start with the number you already know.

Choose a home price when you found a house. Choose a monthly budget when you only know what payment feels comfortable. For this preview, we are using 20% down, 6.50% interest, and a 30-year loan. You can change these on the next page.

$

Use the listing price before your down payment. Commas are added automatically.

These preview results use Step 2 loan settings

20% down · 6.50% interest · 30-year loan. You can change all three on the next page.

What happens next?

We will use this price to estimate the loan, monthly payment, cash needed, and total interest.

These three numbers have the biggest effect on your monthly mortgage payment.

More years usually means a smaller payment but more interest.

Your loan in one sentence

You put down $70,000 and borrow $280,000 for 30 years.

Step 3 of 6

Add the bills that come with owning the home.

A mortgage payment is not the whole monthly cost. Add your best estimates. You can use zero when a cost does not apply.

PMI is often charged when the down payment is under 20%.

Add PMI when down payment is under 20%The calculator removes PMI after the modeled loan reaches 80% of the original home price.
Why these numbers matter

Taxes, insurance, HOA, and PMI add about $500 each month on top of the loan payment.

Step 4 of 6

Would you like to pay the loan off faster?

This step is optional. Leave everything at zero to follow the normal loan schedule.

Extra payments go toward the amount you still owe.

That can shorten the loan and reduce interest. It does not normally replace your required monthly payment.

Example: payment 96 is about eight years after the loan starts.

Your payoff plan

No extra payments are included. The loan follows the normal 30-year schedule.

What if the home price changes?

Five simple prices from 20% lower to 20% higher than your selected home.

80%–120%
How to read it: Taller bars mean a larger estimated monthly total.

What if the interest rate changes?

The home price and down payment stay the same.

How the Bay Area mortgage payment estimate works

A useful home-payment estimate should look beyond principal and interest. This calculator combines the loan payment with the recurring housing costs you enter so you can evaluate a more realistic monthly total.

Start with the home price and down payment

The purchase price minus the cash down payment becomes the estimated loan amount. You can also begin with a target monthly loan budget and let the calculator estimate a supported home price.

Add interest rate, taxes, insurance and HOA

The interest rate and loan term shape principal and interest. Property tax, homeowners insurance, HOA dues, and PMI can then be added to model a broader monthly housing payment.

Compare scenarios before contacting a lender

Use the charts to compare home prices, mortgage rates, and down-payment percentages. Extra-payment tools estimate how additional principal may change interest cost and payoff timing.

Planning a home purchase in the San Francisco Bay Area?

Bay Area prices and monthly housing costs can vary widely across San Francisco, San Jose, Oakland, the Peninsula, the East Bay, the North Bay, and nearby California communities. Enter the actual listing price and your own cost assumptions instead of relying on a one-size-fits-all example.

Bay Area mortgage calculator questions

These answers explain what the calculator includes and where a licensed real estate or mortgage professional is still needed.

What does this Bay Area mortgage calculator include?

It estimates principal and interest and lets you add property taxes, homeowners insurance, HOA dues, and private mortgage insurance when those costs apply.

Is this mortgage estimate a loan approval or rate quote?

No. The results are planning estimates based on the numbers entered. A lender must review income, credit, assets, property details, and current loan pricing before providing actual terms.

Can I compare different home prices, interest rates, and down payments?

Yes. The calculator includes comparisons for home price, interest rate, and down payment so buyers can see how each change may affect the estimated monthly payment.

Can this calculator estimate extra-payment savings?

Yes. You can model recurring extra payments and lump-sum payments to estimate possible interest savings and an earlier payoff date.

Does the estimate include every cost of buying and owning a home?

No. Closing costs, maintenance, repairs, utilities, changing tax bills, and changing insurance prices are not automatically included.
