Mortgage Payment Calculator Spreadsheet | True Monthly Home Cost & Closing Cost | Excel Template

See the true monthly cost of a home—not just principal and interest.

Enter your numbers in the highlighted input cells and instantly review the all-in monthly cost, estimated cash needed at closing, cost breakdown, and budget fit.

Buying a home involves more than the mortgage payment. This polished one-sheet calculator helps you estimate the broader monthly cost of owning a home so you can compare scenarios with clearer numbers. Separate versions are included for Microsoft Excel and native Google Sheets, along with a clean Print Summary.

WHAT THIS TOOL SHOWS

• Estimated all-in monthly housing cost
• Core mortgage payment estimate
• Principal and interest
• Property taxes and homeowners insurance
• Estimated PMI when the down payment is below 20%
• HOA dues, utilities, maintenance reserve, and other entered housing costs
• Monthly cost breakdown and percentage shares
• Estimated down payment and closing costs
• Estimated cash needed at closing

WHY IT IS DIFFERENT

Many basic mortgage calculators stop at principal and interest. This tool gives you a broader planning picture by separating the core payment from the additional costs of owning and maintaining a home. The main calculator keeps the experience simple, while the Print Summary provides a clean view of the completed scenario.
