What is in your monthly payment
- Principal and interest
- The part that pays down the loan and the interest on it. It is set by the loan amount, the rate, and the term.
- Property taxes
- New Jersey taxes are among the highest in the country and vary a lot by town, so this line matters more here than in most states.
- Homeowners insurance
- Required by your lender. Get a quote for the specific home, especially near the shore where flood insurance may also apply.
- Mortgage insurance
- PMI on a conventional loan with less than 20% down. This calculator estimates it at 0.5% of the loan per year.

Mortgage calculator questions
How much are property taxes in New Jersey?
It depends on the town and the home. NJ Division of Taxation data for 2025 shows average residential tax bills of about $9,600 in Woodbridge, $10,600 in Edison, $11,700 in Middletown, and $12,800 in Marlboro. Use the town selector in the calculator to fill in an average, then replace it with the actual tax bill for the home you are considering.
What is included in the monthly mortgage payment?
Principal and interest on the loan, property taxes, homeowners insurance, and private mortgage insurance (PMI) when your down payment is under 20% on a conventional loan. Many lenders collect taxes and insurance monthly in an escrow account.
How does this calculator estimate PMI?
It estimates PMI at 0.5% of the loan amount per year when your down payment is under 20%. Your actual PMI depends on your credit score, loan type, and down payment, and FHA loans use FHA mortgage insurance premiums that are calculated differently.
How much down payment do I need?
It depends on the program: 0% with VA or USDA, 3% with first-time conventional, and 3.5% with FHA. New Jersey first-time buyers may also qualify for NJHMFA down payment assistance of $10,000 to $22,000, depending on county and program.
Does the calculator include HOA dues or flood insurance?
No. If the home has HOA or condo fees, or needs flood insurance, add those to the monthly total separately.
Is this estimate a loan offer?
No. It is an estimate for planning. Your real rate and payment depend on your credit, the property, and the loan program, and a loan officer can quote them for your file.
