Why Use a Mortgage Calculator?

Mortgage payments are not as simple as just repaying the borrowed amount. They usually include:

• Principal – the amount you borrow from the bank or lender.
• Interest – the cost of borrowing the money.
• Taxes – state and local property taxes.
• Insurance – homeowners insurance (and sometimes mortgage insurance).

A mortgage calculator makes it easy to see how these factors add up to your monthly payment.

Without a calculator, it’s easy to underestimate costs and end up stretching your budget. With a calculator, you can:

• Plan your budget more effectively.
• Compare loan offers from different lenders.
• See how much you can afford in different U.S. states.
• Understand how down payment, term length, and interest rate affect your payments.

How to Calculate Mortgage Payments Manually

The formula for calculating a mortgage payment is:

M = P [ r(1+r)^n ] / [ (1+r)^n – 1 ]

Where:

• M = Monthly payment
• P = Loan principal (amount borrowed)
• r = Monthly interest rate (annual rate ÷ 12)
• n = Number of monthly payments (loan term × 12)

Example:

• Loan Amount: $300,000
• Interest Rate: 6% (0.06 ÷ 12 = 0.005 per month)
• Loan Term: 30 years (360 months)

M = 300,000 × [0.005(1+0.005)^360] ÷ [(1+0.005)^360 – 1]
M ≈ $1,799.

👉 Without taxes and insurance, your monthly mortgage payment would be about $1,799.

State-by-State Mortgage Differences

While the basic mortgage formula is the same across the U.S., your total monthly payment can vary significantly by state because of property taxes and insurance rates.

Property Taxes

• New Jersey, Illinois, and New Hampshire tend to have the highest property taxes.
• Hawaii, Alabama, and Colorado are among the lowest.

Homeowners Insurance

• States prone to hurricanes (Florida, Louisiana, Texas) or wildfires (California) typically have higher premiums.

Loan Limits

• The Federal Housing Finance Agency (FHFA) sets conforming loan limits that vary by county.
• High-cost areas like California, New York, and Washington D.C. have higher limits.

2. Not Shopping Around – A difference of even 0.5% in interest can save you thousands over the life of a loan.
3. Overextending Budget – Lenders may approve you for more than you can comfortably afford.
4. Skipping Pre-Approval – Without pre-approval, your home offer may be less competitive.
5. Forgetting Closing Costs – Usually 2–5% of the loan amount.
