Where each input should come from
Interest rate, not APR
The amortization formula uses the mortgage note interest rate. The Consumer Financial Protection Bureau’s interest-rate and APR explanation says APR is a broader measure that includes the interest rate and certain additional charges. Use the lender’s note rate here and compare APR separately.
Taxes and association charges
Use the current property bill or municipal record rather than a statewide percentage. The New Jersey Division of Taxation property-tax overview explains the State framework, but the property-specific amount must be verified. For a condominium or association, review current governing and financial documents for dues and assessments.
Insurance amounts
Use a quote for the actual property and requested coverage. NJDOBI’s homeowners-insurance resources cover homeowners, condominium, and flood-insurance research. Do not assume one policy includes every type of water or flood loss.
Replace the estimate with lender documents
The CFPB Loan Estimate explainer shows where to review loan terms, principal and interest, mortgage insurance, estimated taxes and insurance, lender charges, services, prepaid items, initial escrow, closing costs, and cash to close. Compare the calculator with the document instead of treating the calculator as an offer.
Mortgage insurance
This tool supplies no automatic mortgage-insurance rate. Enter the monthly amount from a lender or Loan Estimate. If you already have a loan, review the disclosure and ask the servicer about the rules that apply. The CFPB’s PMI cancellation resource explains that requirements vary and that FHA and VA loans follow different rules.
Independent counseling
HUD’s housing-counseling directory can connect consumers with participating agencies for pre-purchase, budget, credit, and other housing counseling. HUD also provides multilingual telephone assistance through the contact information on that page.
New Jersey programs and transfer-related costs
NJHMFA’s official homebuyer site lists the agency’s current roadmap, program materials, eligibility resources, participating-lender process, and counseling information. Program names, assistance, limits, rates, and eligibility can change; use the current agency materials and an authorized participating lender instead of relying on a summary here.
This monthly calculator does not calculate deed-transfer charges or decide who owes them. The New Jersey Division of Taxation’s current Realty Transfer Fee page publishes rates, forms, exemptions, and supplemental fee information. Confirm the current legal and transaction treatment with the official source and qualified closing professionals.
Frequently asked questions
Does this calculator determine what I can afford or whether a lender will approve me?
No. It uses only the values entered and does not evaluate income, debts, credit, reserves, loan-program rules, underwriting, or property eligibility. It is not a loan offer or loan approval.
Should I enter the mortgage interest rate or the APR?
Enter the note interest rate quoted by the lender for the principal-and-interest calculation. The CFPB explains that APR is a broader cost measure that includes the interest rate and certain additional charges.
How should I enter mortgage insurance?
Enter the monthly amount shown by the lender or on a Loan Estimate. The calculator does not assume that mortgage insurance applies or select a rate. Requirements and cancellation rules depend on the mortgage and circumstances.
Does the estimate include closing costs or cash to close?
No. Closing costs, lender charges, points, title and settlement charges, inspections, appraisal costs, prepaid items, initial escrow, transfer-related charges, and other cash-to-close items are outside this monthly estimate. Review current lender and transaction documents.
