Our calculators are designed for planning and educational purposes. While highly accurate, they should not replace official calculations from lenders, financial advisors, or legal professionals for binding agreements or official documents.

Several factors can cause differences between our estimates and lender quotes:

• Lenders may use slightly different interest rates
• Additional fees like PMI, insurance, or taxes may be included
• Rounding differences in calculation methods

Always use lender quotes for final decisions, but our calculator is excellent for initial planning and comparison shopping.
