Mortgage Calculator Wiki provides a free browser-based tool for estimating fixed-rate mortgage payments and related housing costs. The purpose is to make the calculation transparent, understandable, and usable without registration.
What the site does
- Estimates principal and interest for a fixed-rate, fully amortizing mortgage.
- Adds user-entered property taxes, homeowners insurance, PMI, and HOA dues.
- Shows an annual amortization schedule and optional extra-payment comparison.
- Provides a simple income and debt ratio check for personal budgeting.
What the site does not do
The site does not originate loans, match consumers with lenders, issue rates, perform underwriting, pull credit, provide preapproval, or represent a government agency. It does not provide financial, legal, tax, insurance, or investment advice.
Editorial standard
Calculation assumptions are published on the methodology page. Consumer explanations are cross-checked against public CFPB guidance. Promotional claims, paid rankings, lender comparisons, and affiliate relationships should be clearly disclosed if added later.
Ownership disclosure
The site owner should replace this paragraph before deployment with the legal owner or publishing entity, a reliable contact method, and any relevant business disclosures. Do not label the website “official” unless that statement is accurate and verifiable.
