What this mortgage calculator includes

This is a full home buying decision tool, not just a payment estimator. It covers monthly cost, upfront cash required, rent vs buy break-even, affordability, and refinance analysis.

The US tab is built for domestic purchases with PMI, closing costs, property tax, and mortgage-interest deduction assumptions. The International tab adds country-specific planning guidance for foreign buyers.

Monthly payment breakdown

P&I, property tax, insurance, HOA, and PMI when applicable.

Cash to close

Down payment, closing costs, and a planning buffer in one number.

Rent vs buy break-even

Includes equity paydown, appreciation, maintenance, and opportunity cost.

Affordability check

Front-end and back-end DTI with lender-style guideline ranges.

Rate sensitivity

See how payment changes if rates move around your assumption.

Amortization schedule

Year-by-year principal, interest, and remaining balance.

Good to know before you use it

All results are estimates. Actual rates, tax treatment, insurance costs, and lender requirements vary by location, credit profile, loan type, and individual circumstance.

The international tab is for planning. Country rates are indicative benchmarks, not guaranteed loan offers for foreign buyers.

The rent vs buy model depends on appreciation, rent growth, and opportunity-cost assumptions. Small input changes can move the break-even by years.

This calculator is not financial, tax, or legal advice.

Frequently asked questions

How is the monthly payment calculated?+
Your principal and interest uses the standard amortization formula. The calculator adds property tax, homeowners insurance, HOA, and PMI when applicable to arrive at the full monthly payment.
What's included in cash to close?+
Down payment, estimated closing costs, and a 3-month planning buffer. The buffer is a planning guideline, not a universal lender requirement.
How does rent vs buy break-even work?+
The tool compares cumulative ownership costs against cumulative rent while crediting equity gains and accounting for the opportunity cost of your down payment.
When does PMI go away?+
Once your loan balance reaches 80% of the original purchase price, you can usually request cancellation. The calculator estimates when that point is reached.
Can foreigners get a mortgage abroad?+
Sometimes, yes, but rules vary widely by country, lender, and residency status. The international tab is for planning estimates, not guaranteed loan availability.
How do bi-weekly payments save money?+
They create one extra full payment per year, which reduces principal faster and saves interest over time.
What DTI do lenders want?+
Many conventional lenders prefer front-end DTI at or below 28% and back-end DTI at or below 36–43%, though exceptions exist.
How does the refinance calculator work?+
It compares your current remaining loan against a new loan and shows monthly savings, break-even months, and estimated lifetime savings.
