Principal
The portion of your payment that reduces your loan balance. As the balance falls, more of each payment shifts to principal.
Interest
The cost of borrowing, charged on your remaining balance each month. Early in a loan, most of your payment is interest.
Property Taxes
Local property taxes, often escrowed into your monthly payment and paid by the servicer on your behalf.
Homeowners Insurance
Coverage that protects your home and belongings, usually required by lenders and escrowed monthly.
PMI
Private mortgage insurance that may be required on conventional loans when the down payment is less than 20%.
HOA Fees
Homeowners association dues, when your property is part of an HOA, added to your total monthly housing cost.
Common mortgage questions, answered
What does a mortgage calculator calculate?
It estimates your monthly mortgage payment — principal and interest — and, when you add them, property taxes, homeowners insurance, PMI, and HOA fees so you can see your total monthly housing cost.
How is a monthly mortgage payment calculated?
Using the amortization formula M = P × [r(1+r)^n] / [(1+r)^n − 1], where P is the loan amount, r is the monthly interest rate, and n is the total number of monthly payments.
Does the calculator include property taxes and insurance?
Yes — enter an annual property tax amount or a percentage of home value, and your annual homeowners insurance premium; both are divided across the year into your monthly payment.
What is PMI?
Private mortgage insurance protects the lender and is usually required when your down payment is less than 20% of the home price.
How much should I put down on a house?
It depends on your budget and loan type. A larger down payment lowers your loan amount and monthly payment and may help you avoid PMI, but 20% down is not required for every loan.
Can extra payments reduce mortgage interest?
Yes — extra payments go straight to principal, lowering future interest and shortening your loan term. Even small recurring extras add up over time.
