Planning-only estimate using the fixed conventions above. For a strict quote, confirm lender-specific PMI tiers, removal dates and any optional refinance/portfolio pricing assumptions.

How this was calculated

Base loan = home price − down payment (3.50% down).

Conventional principal and interest use the entered term and rate with the base loan.

PMI is estimated as annual PMI rate × financed amount ÷ 12 for the entered PMI duration.

Housing cost = principal and interest + tax + insurance + HOA + (estimated PMI when applicable).

How this estimate is built

This page models a fixed-rate conventional mortgage with a standard amortization schedule. The headline is principal-and-interest plus recurring property-tax, insurance, HOA, and optional PMI where your entered down payment is below 20%.

PMI in this calculator is entered as an annual rate and treated as a planning estimate over the duration you set.

What to check after the result

Compare this payment against your lender quote and against a rent and emergency-fund plan. If PMI is shown, verify removal conditions and exact loan-level pricing terms before finalizing.

If down payment, income, debt obligations or tax treatment changes, re-run this result quickly; this is a high-leverage planning step, not an approval promise.

Frequently asked questions

Can this replace a lender quote?

No. It is a planning estimate. Lenders may vary rates, PMI terms, fees and qualification thresholds.

Why is PMI included in this result?

Conventional PMI is common below 20% down and often changes with loan balance and LTV. This tool uses your entered assumptions for planning and does not reflect lender-specific repricing rules.
