How a Mortgage Calculator Works
A mortgage calculator uses several financial inputs to estimate monthly loan payments.
Home Price
The purchase price of the property serves as the foundation for the calculation.
Down Payment
A larger down payment generally reduces the loan amount and monthly payment.
Interest Rate
The loan’s interest rate significantly impacts the total cost of borrowing.
Loan Term
Common loan terms include:
- 15-year mortgage
- 20-year mortgage
- 30-year mortgage
Longer terms often result in lower monthly payments but higher overall interest costs.
Taxes and Insurance
Property taxes and insurance premiums are frequently included to provide a more realistic payment estimate.
