What is the Mortgage Calculator?

The Mortgage Calculator estimates your complete monthly housing payment—including principal, interest, property taxes, homeowners insurance, and HOA fees—so you know exactly what to expect before buying a house.

It analyzes values such as home price or rent, down payment, rate, tax and insurance and returns insight through outputs like monthly housing cost, affordability range, equity projection, ownership gap.

This structure helps you compare alternatives, understand trade-offs, and identify whether your current strategy is aligned with your goals.

How to Use the Mortgage Calculator

1

Enter realistic values for home price or rent, down payment, rate, tax and insurance based on your current situation.

2

Review default assumptions and adjust them to match your market, risk profile, and timeline.

3

Run the calculation and review core outputs such as monthly housing cost, affordability range, equity projection, ownership gap.

4

Test at least three scenarios (conservative, expected, and optimistic) to understand range of outcomes.

Example Scenario

Example: The hidden costs of homeownership

You find a $400k house and plan to put 5% down with a 6.5% interest rate. Property taxes are $4,000/year and insurance is $1,200/year.

  • Enter $400,000 home price and 5% down payment.
  • Set interest rate to 6.5% and loan term to 30 years.
  • Add $4,000 annual property tax and $1,200 annual insurance.
Takeaway

While the pure loan payment (Principal + Interest) is only $2,401, adding taxes, insurance, and PMI pushes the true monthly cost to nearly $3,000.

Frequently Asked Questions

PITI stands for Principal, Interest, Taxes, and Insurance. It represents the four core components of a standard monthly mortgage payment.

If you put down less than 20% on a conventional loan, lenders usually require you to pay PMI every month to protect them in case you default. It typically ranges from 0.5% to 1.5% of the loan amount annually.
