HomeMathKit is an independent, free mortgage-planning software project maintained in Dheeraj Namburu's public repository. It is not a lender, broker or financial advisory service.
Designed around the decision
The goal is to make inputs visible, separate debt payments from other housing costs, and let people compare reproducible scenarios without an account. Results are estimates, not offers or underwriting decisions.
How the work can be checked
The calculation code, automated tests and assumptions are published with the project. No professional mortgage, legal or tax review is claimed. Read the methodology and verify inputs against your lender's disclosures.
Independence and advertising
Advertising may support this free service when enabled. Ad placements are separated from inputs and results. Advertising does not change the formulas or determine which modeled scenario has the lowest cost. No lender offers or paid rankings are currently provided.
