What this tool does
Estimate principal, interest, taxes, insurance, PMI, HOA, and mortgage payoff.
Method
Fixed-rate principal and interest use the standard amortization formula; optional property costs and extra payments are added separately and reconciled to a month-by-month schedule.
Example
Compare a 30-year $320,000 loan at 6.5% with and without a $150 extra monthly payment.

Common questions
Is it free?
Yes. The core tool and its standard result or export are free to use.
Do I need an account?
No for the core utility. An account or private management token is requested only for capabilities that must persist, such as editable dynamic QR links.
Can I trust the result?
The method and assumptions are visible above. Time-sensitive tools name their sources and freshness; important financial, safety, legal, or operational decisions should be verified with the primary authority.
