Mortgage Calculator 2026 – Monthly Payment with Taxes, Insurance, PMI, Manufactured Homes & More

What Is a Mortgage Calculator and How Does It Work?

A mortgage calculator is a financial tool that tells you exactly how much your monthly home loan payment will be based on your home price, down payment, interest rate, and loan term. Our free mortgage calculator goes further than most — it includes property taxes, homeowner's insurance, and PMI (Private Mortgage Insurance) to show your true PITI payment. PITI stands for Principal, Interest, Taxes, and Insurance, and it represents the full cost you will pay each month as a homeowner.

Most people only think about the principal and interest portion when budgeting for a home. However, property taxes and insurance can add hundreds of dollars to your monthly payment — sometimes 20 to 30 percent more than the base mortgage payment alone. This calculator also works as a mortgage calculator for manufactured homes, a land loan calculator with amortization schedule, and a second mortgage calculator — covering a wide range of property and financing types in one free tool.

How Much Is a Mortgage on a $400k Home?

One of the most common questions in 2026 is: how much is a mortgage on a $400k home? The honest answer is: it depends on your down payment, credit score, interest rate, loan term, and whether you include taxes and insurance. Here is a practical breakdown with real numbers.

Use the calculator above to enter your exact numbers. Changing the down payment by even $10,000–$20,000 shifts your monthly payment noticeably and determines whether PMI applies.

Mortgage Calculator for Manufactured Homes

If you are buying a manufactured home (also called a mobile home or prefab), your financing options and loan terms differ meaningfully from a traditional site-built home. Our calculator works for manufactured home loans — simply enter your purchase price, down payment, and the interest rate your lender quotes.

Here is what makes manufactured home financing unique compared to standard mortgages:

• Chattel loans: If the manufactured home is not permanently affixed to owned land, it is classified as personal property and financed with a chattel loan. These carry higher interest rates (8–12%) and shorter terms (15–20 years), resulting in higher monthly payments than traditional mortgages.
• FHA Title I loans: The FHA offers manufactured home loans with down payments as low as 5% and flexible credit requirements (580+ credit score). A solid option for buyers who cannot qualify for conventional financing.
• Conventional loans (MH Advantage): Fannie Mae's MH Advantage program allows manufactured homes meeting specific construction standards to qualify for conventional financing with as little as 3% down and standard mortgage rates — much lower than chattel loan rates.
• VA loans for manufactured homes: Eligible veterans can finance a permanently affixed manufactured home with zero down payment if it meets VA property standards. No PMI applies on VA loans.

When using this as a manufactured home mortgage calculator, always use the rate quoted by your specific lender, since rates vary considerably based on whether the home is on owned land, rented land, or a permanent foundation.

Land Loan Calculator – Amortization Schedule for Raw Land Purchases

Buying raw land, a rural lot, or agricultural acreage is very different from purchasing a home. Land loans are considered higher risk by lenders because vacant land generates no income and has a less liquid resale market. As a result, land loan terms are stricter and more expensive than traditional mortgages.

To use this page as a land loan calculator with amortization schedule, enter the land price as your "Home Price," your down payment, the land loan interest rate, and the term. The amortization math is identical — every payment showing principal vs. interest applies to land loans exactly as it does to home mortgages.

Land Type	Typical Down Payment	Interest Rate Range	Typical Loan Term
Raw / Unimproved Land	30–50%	8–12%	5–10 years
Unimproved Lot (utilities nearby)	20–30%	7–10%	10–15 years
Improved Lot (with utilities)	15–25%	6–9%	15–20 years
Rural Land (USDA eligible)	0–10%	5–7% (USDA)	Up to 30 years

Many buyers search for a loan calculator UFCU-style tool when modeling a rural or land purchase through a credit union like University Federal Credit Union. The calculator above uses the same standard amortization math any credit union or bank applies — just enter the rate and term your institution quotes to get an accurate payment and interest breakdown.

One critical note on land loans: many carry balloon payments, meaning the full remaining balance is due at the end of a shorter term (say 5 or 7 years), requiring you to pay off or refinance at that point. Always ask your lender explicitly about balloon payment terms before signing any land loan agreement.

What Is a 15/1 ARM Mortgage? Understanding Adjustable Rate Loans

A 15/1 ARM mortgage is a hybrid adjustable-rate mortgage that keeps a fixed interest rate for the first 15 years, then switches to a rate that adjusts once per year for the remaining loan term. The "15" refers to the fixed period in years, the "1" indicates annual adjustments after that.

The 15/1 ARM sits in an interesting niche compared to other ARM products. It offers a lower starting rate than a 30-year fixed — often 0.5 to 1.0 percentage points lower — while providing 15 full years of payment stability. Compare this to the more common 5/1 ARM and 7/1 ARM, which only lock your rate for 5 or 7 years before adjustments begin.

ARM loans use a market index (typically SOFR — Secured Overnight Financing Rate) plus a fixed margin set by the lender. Most ARMs include rate caps: a common structure is 2% per adjustment period and a 5–6% lifetime cap above the starting rate. To model a 15/1 ARM in our calculator, enter your initial fixed rate and the 15-year term. For risk planning, also run the calculator with the rate increased by 2–3% to understand your worst-case payment if the rate adjusts upward.

Second Mortgage Calculators – Home Equity Loans and HELOCs

A second mortgage is any loan secured by your home that sits behind your primary mortgage in repayment priority. Homeowners use second mortgages to tap the equity they've built — typically for home renovations, debt consolidation, college tuition, or major purchases. The two most common types are home equity loans and HELOCs.

• Home Equity Loan (Fixed Second Mortgage): A lump-sum loan with a fixed interest rate and fixed monthly payment, taken in addition to your first mortgage. You receive all funds upfront and repay in equal installments over a set term (typically 5–15 years). Rates are usually 1–3% higher than first mortgage rates.
• HELOC (Home Equity Line of Credit): A revolving credit line secured by your home equity, similar to a credit card. You draw funds as needed during the draw period (typically 10 years) and repay during the repayment period. HELOCs carry variable rates that fluctuate with prime rate.

To use this as a second mortgage calculator, enter only the second loan amount as "Home Price" and set down payment to zero. Enter the second mortgage's interest rate and term. The monthly payment shown represents your additional housing cost. Add this to your existing first mortgage payment for your total monthly obligation.

Mortgage Payment Formula – How Monthly Payments Are Calculated

Your principal and interest payment is calculated using the standard amortization formula used by every lender, credit union, and bank:

Monthly Payment (P&I) = [L x r x (1 + r)^n] / [(1 + r)^n - 1]

Where L is your loan amount (home price minus down payment), r is your monthly interest rate (annual rate divided by 12), and n is the total number of monthly payments (loan term in years multiplied by 12). Your total PITI payment is then this base payment plus monthly property tax, homeowner's insurance, and PMI. This same formula drives every result — whether you are calculating a conventional mortgage, a manufactured home loan, a land loan amortization schedule, or a second mortgage payment.

Real Example – $300,000 Mortgage Payment Calculation

Scenario: Home price $300,000. Down payment $60,000 (20%). Loan amount $240,000. Interest rate 7%. Loan term 30 years. Annual property tax $3,600. Annual homeowner's insurance $1,200. PMI $0 (20% down eliminates PMI on conventional loans).

Monthly rate: 7% / 12 = 0.5833%. Number of payments: 30 x 12 = 360. P&I = approximately $1,597/month. Add taxes ($300/month) and insurance ($100/month). Total PITI = $1,997/month. The calculator above does all of this instantly for any home price — whether $150,000, $400,000, or $800,000.

What Is Included in a Mortgage Payment? (PITI Explained)

• Principal: The portion of your payment that directly reduces your loan balance. In the early years of a mortgage, most of your payment goes toward interest rather than principal — this gradually shifts through the process of amortization.
• Interest: The cost of borrowing. Your rate is determined by your credit score, loan type, down payment, and current market conditions. Even a 0.5% difference in rate can save or cost tens of thousands of dollars over the life of a loan.
• Property Taxes: Assessed annually by local governments and collected monthly by your lender into an escrow account. Property tax rates range from under 0.5% in some states to over 2% in others.
• Homeowner's Insurance: Required by virtually all lenders. Annual premiums typically run $800–$2,500 for a standard home. Manufactured homes and properties in high-risk areas may carry higher premiums.
• PMI (Private Mortgage Insurance): Required on conventional loans when your down payment is below 20%. Costs 0.5%–1.5% of the loan annually. Cancellable once you reach 20% equity. Land loans and chattel loans for manufactured homes do not use PMI but may have their own insurance requirements.

15-Year vs 30-Year Mortgage – Which Is Better?

A 30-year mortgage offers the lowest monthly payment, freeing up cash for other expenses, savings, or investments. On a $300,000 loan at 7%, total interest over 30 years is approximately $418,000.

A 15-year mortgage costs 30–40% more per month but typically comes with a lower interest rate (0.5–1.0% less) and cuts your interest costs dramatically. On the same $300,000 loan at 6.5%, total interest drops to roughly $168,000 — saving approximately $250,000. You also build equity twice as fast.

There is also a compelling middle-ground: the 15/1 ARM, which combines a lower starting rate with 15 years of payment stability — worth modeling if you plan to sell or refinance before the fixed period ends.

Down Payment Requirements by Loan and Property Type

• 3% down: Conventional first-time buyer programs (Fannie Mae / Freddie Mac). PMI required until 20% equity.
• 3.5% down: FHA loans (580+ credit score). Also available for qualifying manufactured homes under FHA Title II.
• 5–10% down: Standard conventional loans. PMI required but removable at 20% equity.
• 10–20% down: Common threshold for manufactured home and second mortgage financing.
• 20%+ down: Eliminates PMI on conventional loans. Required baseline for improved lot purchases and land loan financing in many cases.
• 30–50% down: Typical for raw land and unimproved lot loans, reflecting the higher risk lenders associate with vacant land.
• 0% down: VA loans (eligible veterans, no PMI) and USDA loans (eligible rural areas, including some land and manufactured home scenarios).

How Your Credit Score Affects Your Mortgage Rate

Your credit score is one of the most powerful levers in determining your mortgage interest rate. As a benchmark in 2026: 760+ qualifies for the best conventional rates; 700–759 earns slightly higher rates; 660–699 may pay 0.5–1.0% more; below 620 typically requires FHA financing. On a $300,000 loan over 30 years, a 1% rate difference translates to about $197/month and over $70,000 in total interest.

For manufactured home loans and land loans, credit score matters even more — since these products already carry higher baseline rates, improving your score from 640 to 720 before applying can make a proportionally larger difference in your monthly payment and total cost.

Fixed-Rate vs Adjustable-Rate Mortgage (ARM) — Which Should You Choose?

A fixed-rate mortgage locks in your rate for the entire loan term — your principal and interest payment never changes regardless of market conditions. This is the most popular choice for buyers planning long-term homeownership.

An adjustable-rate mortgage (ARM) starts with a lower fixed rate for an initial period, then adjusts periodically based on a market index like SOFR. Common products include 5/1, 7/1, and 15/1 ARM loans. The longer the initial fixed period, the closer the starting rate approaches a fixed mortgage rate — but savings over the fixed window can still be substantial on large balances. ARMs work well for buyers with defined short-to-medium term ownership plans.

PMI — How to Avoid It and When It Disappears

PMI is temporary on conventional loans. The Homeowners Protection Act gives you the legal right to request PMI cancellation when your balance reaches 80% of the original home value; your lender must automatically cancel it at 78%. If your home has appreciated in value, requesting a new appraisal may allow you to remove PMI earlier than your original schedule would suggest.

For FHA loans with less than 10% down, MIP (mortgage insurance premium) persists for the full life of the loan — refinancing into a conventional loan once you reach 20% equity is the only path to elimination. Manufactured home chattel loans and land loans do not use PMI in the conventional sense, but lenders may require specific hazard insurance coverage as a loan condition.

Frequently Asked Questions

Q: How much is a mortgage on a $400k home?
A: With 20% down at 7% over 30 years, your principal and interest is approximately $2,129/month. Including estimated taxes and insurance, expect $2,600–$2,800/month total PITI. With 5% down, add PMI and budget closer to $3,100–$3,300/month. Use the calculator above with your specific numbers for an exact figure.

Q: Can I use this as a mortgage calculator for manufactured homes?
A: Yes. Enter the manufactured home purchase price, your down payment, and the interest rate your lender quotes. Manufactured home loan rates vary based on loan type — chattel loans run 8–12%, FHA Title I loans are lower, and Fannie Mae MH Advantage programs can match conventional mortgage rates for qualifying homes.

Q: How does a land loan calculator with amortization schedule work?
A: Enter the land price as Home Price, set your down payment (20–50% typically required for raw land), enter the land loan interest rate, and choose a term. The calculator shows your monthly payment and full amortization breakdown — exactly how much of each payment goes to principal versus interest over the full loan life.

Q: What is a 15/1 ARM mortgage and is it a good deal?
A: A 15/1 ARM gives you a fixed rate for 15 years, then adjusts once per year. If you plan to sell or refinance before the 15-year mark — which is true for most homeowners — you capture a lower starting rate without ever experiencing an adjustment. If you might stay beyond 15 years, a 30-year fixed offers more long-term payment certainty.

Q: How do I use second mortgage calculators?
A: Enter the second loan amount as Home Price, set down payment to zero, enter the second mortgage rate (typically 1–3% above first mortgage rates), and select your term. The monthly payment shown is your additional housing cost. Add it to your existing first mortgage payment to find your total monthly obligation.

Q: What is a loan calculator UFCU and how is it different?
A: UFCU (University Federal Credit Union) and similar credit unions use the same standard amortization formula to calculate loan payments that this calculator uses. Simply enter the rate and term your credit union quotes — whether for a home loan, manufactured home financing, or land purchase — and the results will match what your loan officer would show you.

Q: How much mortgage can I afford on my income?
A: A common guideline says your monthly PITI should not exceed 28% of your gross monthly income. For $5,000/month income, the maximum is $1,400/month in total mortgage payment. Your combined debt payments (mortgage + car + student loans + credit cards) should stay below 36% of gross income.

Q: Does paying extra toward my mortgage really save money?
A: Significantly. On a 30-year $300,000 mortgage at 7%, paying an extra $200/month shortens your payoff by about 6 years and saves roughly $80,000 in total interest. Use the extra payment field in the calculator to model exactly how much you can save with your specific loan.

Q: What is an escrow account in a mortgage?
A: An escrow account is held by your mortgage servicer and funded by the tax and insurance portions of your monthly payment. When your property tax and insurance bills come due, the servicer pays them directly from escrow. This ensures critical bills are never missed and eliminates the need for you to save separately for large lump-sum payments each year.
