Find answers to common questions about how our calculators work, what the results mean, and how your data is handled. If you have a question not covered here, feel free to reach out to us.
Our calculators use standard financial and mathematical formulas widely used in the real estate, lending, and home improvement industries. The results you receive are estimates based on the inputs you provide and a set of reasonable assumptions built into each tool.
That said, calculator results are not guarantees. Real-world outcomes depend on many factors that inputs alone cannot capture, including lender-specific pricing, local property taxes, insurance premiums, HOA fees, current market conditions, project complexity, material prices, and timing. Use our tools as a starting point, then get actual quotes and professional guidance before committing to any major decision.
Calculators apply standardized formulas to the numbers you provide. Real-world quotes reflect additional variables that change by situation: origination fees, discount points, credit score adjustments, local tax rates, insurance premiums, lender overlays, and material or labor costs in your specific area.
A mortgage calculator, for example, estimates principal and interest. Your actual monthly payment may also include property taxes, homeowner's insurance, and private mortgage insurance depending on your loan structure. Think of our results as a frame of reference that helps you ask sharper questions when you talk to a professional.
Each calculator is built around a specific set of inputs and assumptions. Common examples include:
Where assumptions are significant, the educational section on each calculator page explains them in detail. Adjust your inputs to reflect your real situation as closely as possible for the most relevant result.
Our calculators follow standard industry methods. A few concrete examples:
Each calculator page includes a plain-language walkthrough of its formula with worked examples. Look for the educational section below the calculator inputs on any tool page.

Absolutely. That is exactly how we encourage people to use them.
