About HomeownerMath

HomeownerMath.com creates free calculators to help homeowners estimate common costs and compare options before making expensive decisions.

Our calculators cover mortgage payoff and refinance scenarios, home equity comparisons, roof replacement estimates, solar panel payback periods, and more. Each calculator shows the assumptions behind the numbers so you can understand the math — not just trust it.

We are not a lender, contractor, solar installer, or insurance company. We do not sell financial products or home services. We build tools that help you ask better questions before you talk to someone who does.

What We Believe

• Homeowners deserve clear, honest estimates before making expensive decisions.
• Calculators should show their work — assumptions, formulas, and limitations included.
• No calculator can replace professional advice, but a good one can help you prepare for it.
• Trust is earned through transparency, not hype.

Important Disclaimer

Our calculators are educational tools and are not financial, legal, tax, insurance, or construction advice. Results are estimates based on simplified models and assumptions. Always consult qualified professionals before making major financial or home improvement decisions.
