## FAQs

### Does this mortgage calculator include taxes and insurance?

Yes. It estimates principal and interest from home price, down payment, rate, and term, then adds estimated property tax and homeowners insurance. State averages can prefill those fields—edit any amount. Educational estimates only—not a tax bill or insurance quote.

### How does PMI work in this mortgage calculator?

For Conventional loans, monthly private mortgage insurance is estimated when loan-to-value is above 80% (under about 20% down). PMI can prefill from state averages and is editable. FHA, VA, and USDA paths do not use conventional PMI in this tool. Educational estimates only.

### Can I estimate mortgage payment by credit score range?

Yes. Excellent (740+), Good (670–739), Fair (580–669), or Poor (below 580) preset an illustrative note rate, or type a quote. No credit pull; not a lender offer. Example: https://financeflow.studio/?credit=good

### How do extra payments affect my mortgage payoff?

Extra principal is applied on the amortization schedule by amount, frequency, and start date. That can shorten the loan and lower total interest. When extras are active, the tool shows interest saved and an updated payoff date.

### What is included in the payment breakdown?

Monthly, yearly, or lifetime totals for principal and interest, extra principal, homeowners insurance, HOA, PMI (when applicable), and property tax.

### Are FinanceFlow purchase results a loan offer?

No. Educational tool only. Not offers, pre-approvals, or professional advice. FinanceFlow is not a lender or mortgage broker.
