About Mortgage Calculator

Calculation identity

The app uses the standard fixed-rate amortizing-loan payment formula, a full monthly amortization schedule, explicit user-entered recurring housing-cost assumptions, and the preserved Mycelgrid extra-principal cadence.

What it does not claim

It does not fetch current mortgage rates, qualify a borrower, determine affordability, model adjustable rates, calculate APR or closing costs, decide tax treatment, infer mortgage-insurance rules, or check prepayment penalties.

Privacy, data and limits

Mortgage Calculator processes the current fixed-rate mortgage scenario, amortization schedule, and extra-principal plan only in this browser page. It does not upload mortgage assumptions or results, maintain an app-owned calculation history, account, cloud copy, or recovery service. Share App shares only the canonical app URL, not entered values or results.

Results are mathematical planning estimates using the home price, down payment, fixed annual interest rate, term, and optional housing-cost assumptions you enter. The app does not fetch current rates, determine lender approval or affordability, calculate APR or closing costs, model adjustable rates, determine tax treatment, infer mortgage-insurance eligibility or cancellation, apply escrow law, or check prepayment penalties. Actual loan documents and lender servicing practices control real payments. The app does not provide individualized financial, tax, legal, lending, or investment advice.
