What Is the Cost of Homeownership Calculator?

The Cost of Homeownership Calculator is an interactive tool that helps you understand the full Financial impact of buying a home. It's more than just a mortgage payment tool โ€” it includes ongoing expenses like property taxes, insurance, maintenance, utilities, and even opportunity costs. It also compares homeownership to renting, so you can make informed decisions based on your lifestyle, goals, and budget.

How the Calculator Helps You

This tool can be useful if you're:

  • Considering buying your first home
  • Comparing renting vs owning
  • Evaluating your home loan affordability

It brings clarity to questions like โ€œCan I afford this house?โ€ or โ€œIs renting a better option right now?โ€ by factoring in all the hidden costs many buyers overlook.

Key Formula Used

The calculator uses several important formulas to estimate monthly and long-term costs. Here's one of the most essential for calculating monthly mortgage payments:

Monthly Payment = P ร— [ r(1 + r)n ] / [ (1 + r)n โ€“ 1 ]
  • P = Loan Amount (Home Price โ€“ Down Payment)
  • r = Monthly Interest Rate (Annual Rate รท 12 รท 100)
  • n = Total Number of Payments (Years ร— 12)

This formula helps create your monthly mortgage planner by calculating the principal and interest portion of your payment.
