A New Hampshire mortgage payment is principal and interest plus property tax, homeowners insurance and, with less than 20% down, private mortgage insurance. In New Hampshire the property tax line is the one that swings most, because every town sets its own rate: on the same $450,000 house, the 2025 NH DRA rates make the tax $440.25 a month in Thornton and $891.38 in Plymouth.
Key takeaways
- PITI is principal, interest, taxes and insurance. Most lenders collect the T and I monthly in an escrow account and pay the bills for you.
- The town matters as much as the rate. On a $360,000 loan, moving from Thornton to Plymouth adds $451.13 a month in tax, more than a full percentage point on the interest rate adds ($239.15).
- New Hampshire has no income tax on wages and no general sales tax, but buyers pay a real estate transfer tax of $0.75 per $100 at closing under RSA 78-B.
- PMI can be cancelled on request when the balance is scheduled to reach 80% of the home's original value and ends automatically at 78% (CFPB).
- Use your own quoted rate. National averages are a benchmark, not an offer.

NH mortgage calculator: principal, interest, taxes and insurance
This New Hampshire mortgage calculator sets the property tax from the town you pick, using that town's 2025 NH DRA rate, where most results for "mortgage calculator NH" or "mortgage calculator New Hampshire" apply one statewide rate. It opens on a $400,000 home in Plymouth with 20% down at 6.5% for 30 years, about $2,898 a month.
To run your own numbers, enter the price, move the down payment, pick a 15-, 20- or 30-year term, type the rate a lender quoted you into the Interest Rate box, then choose the town. The result shows principal and interest, property tax and homeowners insurance, plus PMI when the down payment is under 20%.
Three of those lines are estimates. The tax line applies the town rate to the price, as if the home were assessed at it; the home's tax card gives the real assessment. Insurance is figured at 0.25% of the price a year (at least $800), and PMI at 0.6% of the loan a year, so replace both with your own quotes. The calculator has no HOA line, so add condo or association dues yourself.

Property tax: Plymouth’s 2025 total rate of $23.77 per $1,000 of assessed value (NH DRA), applied to the price as if the home were assessed at it; a village or precinct district can carry a different rate. Insurance at 0.25% of home value/yr and PMI below 20% down are Owl’s Nest Real Estate estimates. Use the rate your lender quotes; confirm the assessment with the town.
How is a mortgage payment calculated?
A fixed-rate mortgage payment is calculated with the standard amortization formula, which spreads principal and interest into equal monthly payments over the loan term:
M = P × r × (1 + r)^n ÷ ((1 + r)^n − 1)
Here P is the loan amount, r is the annual interest rate divided by 12, and n is the number of monthly payments (360 for a 30-year loan, 180 for a 15-year loan). The result is principal and interest only. Taxes, insurance, PMI and HOA dues are added on top.
On a $360,000, 30-year loan at 7.24% (Freddie Mac's national average as of October 29, 2026), M works out to $2,453.39 a month. In the first month, $2,172.00 of that is interest and only $281.39 goes to principal; the split shifts toward principal every month after. Over 30 years that loan pays $523,222 in interest if it is never prepaid or refinanced.
The term changes the picture more than people expect. The same $360,000 over 15 years at 6.60% is $3,155.81 a month, $702.42 more, but total interest falls to $208,046.
What does PITI include in New Hampshire?
PITI in New Hampshire means principal, interest, property taxes and homeowners insurance, and for most buyers the last two are paid through escrow. The lender adds one-twelfth of the annual tax and insurance to each payment, holds it, and pays the town and the insurer when the bills are due.
- Property tax is the town's total 2025 rate × assessed value ÷ 1,000. New Hampshire towns bill most commonly twice a year, with the second bill using the newly set rate, so escrow often gets adjusted after your first December bill.
- Homeowners insurance depends on the house, its age, the distance to a fire station and hydrant, and your deductible. Get a quote before you lock the rate; our calculator uses a placeholder of 0.25% of the price a year until you have one.
- PMI applies to most conventional loans with less than 20% down. FHA, VA and USDA loans have their own insurance or guarantee fees.
- HOA or condo fees are not part of PITI, but they are part of what you can afford, so add them to the calculator's total yourself.
Some New Hampshire addresses also pay a village district rate on top of the town's. Inside Waterville Estates on the Campton side, the 2025 total rate is $23.13 per $1,000 instead of Campton's $17.46. The calculator's town picker uses the town rate only. For an address inside a district, find the district rate in our table of NH property tax rates by town and add the difference: on a $450,000 Waterville Estates home on the Campton side, the district's $5.67 adds $212.63 a month to what the calculator shows.
Why does the town change your NH mortgage payment so much?
The town changes a New Hampshire mortgage payment because property tax is set town by town, and the 2025 rates near Plymouth range from $9.96 per $1,000 in Waterville Valley to $23.77 in Plymouth. Here is the same $450,000 house, financed with 20% down at 7.24% for 30 years, with $1,800 a year of insurance assumed for the arithmetic (not an average premium):
| Town (2025 DRA rate) | Principal and interest | Property tax per month | Insurance | Monthly PITI |
|---|---|---|---|---|
| Thornton ($11.74) | $2,453.39 | $440.25 | $150.00 | $3,043.64 |
| Campton ($17.46) | $2,453.39 | $654.75 | $150.00 | $3,258.14 |
| Waterville Estates, Campton side ($23.13) | $2,453.39 | $867.38 | $150.00 | $3,470.77 |
| Plymouth ($23.77) | $2,453.39 | $891.38 | $150.00 | $3,494.77 |
The tax column assumes an assessment equal to the $450,000 price. Real assessments are often lower than the price, so treat these as examples, not bills.
The contrarian lesson is that the interest rate gets all the attention while the town quietly moves the payment more. Plymouth's tax costs $451.13 a month more than Thornton's on this house; a full point higher rate (7.24% instead of 6.24%) costs $239.15 more. Plymouth gives you a downtown, Plymouth State University and the hospital close by, and Thornton is a longer drive to services, so the right answer depends on the buyer. The point is to run both. Our Plymouth vs Campton vs Thornton comparison covers the rest of that trade.
Worked example: a $450,000 home in Campton, NH
A $450,000 Campton home with 20% down at 7.24% for 30 years comes to about $3,258 a month in PITI, using Campton's 2025 DRA rate of $17.46 per $1,000 and an assumed $1,800 a year for insurance. Here is the arithmetic step by step:
- Down payment and loan. 20% of $450,000 is $90,000, leaving a $360,000 loan.
- Principal and interest. At 7.24% for 360 months, the amortization formula gives $2,453.39.
- Property tax. $450,000 ÷ 1,000 × $17.46 = $7,857 a year, or $654.75 a month, if the home is assessed at its price.
- Insurance. $1,800 ÷ 12 = $150.00 a month (our assumption for the example; use your quote).
- Total PITI. $2,453.39 + $654.75 + $150.00 = $3,258.14 a month, with no PMI at 20% down.
At closing, the buyer's share of the New Hampshire transfer tax on $450,000 is $3,375 ($0.75 per $100, rounded to the whole dollar), and the seller pays the same. Lender fees, title insurance and the escrow cushion come on top; our guide to closing costs in New Hampshire has a calculator for the cash to close.
The same house at 5% down is a $427,500 loan and $2,913.40 a month in principal and interest before PMI, $460.01 more than at 20% down. PMI pricing depends on credit score and loan-to-value. Our calculator uses 0.6% of the loan a year as a placeholder, but ask your lender for the real figure.
What are current mortgage rates in New Hampshire?
Mortgage rates New Hampshire lenders quote follow the national market, and as of October 29, 2026 Freddie Mac's Primary Mortgage Market Survey put the U.S. average 30-year fixed rate at 7.24% and the 15-year fixed at 6.60%, against 6.17% and 5.41% a year earlier. Those are the figures our examples use.
Freddie Mac publishes a new survey every Thursday at noon Eastern, so the figures above will be out of date within a week. To check the current figure, open the PMMS page and read the latest weekly 30-year and 15-year averages, then type your own quoted rate into the calculator above.
That average is not your rate. Current NH mortgage rates track the benchmark, but a New Hampshire borrower's quote depends on credit score, down payment, loan type, points, the property (a condo, a second home or a multi-family all price differently) and the day the rate is locked. If you searched "current mortgage rates New Hampshire" or "mortgage rates NH today", the honest answer is a written Loan Estimate from two or three lenders on the same day, not a number on a website, including this one.
Mortgage rates NH and ME borrowers are quoted come from the same national market. What differs between New Hampshire and Maine is the closing cost and tax side, not the rate sheet.
How do you find the best mortgage rates in NH?
The best mortgage rate in NH is the lowest total cost you can get in writing, which means comparing Loan Estimates rather than advertised rates. Ask each lender for a Loan Estimate on the same loan amount, term and lock period, on the same day, and compare the rate, the points and the lender fees together. A lower rate bought with points only pays off if you keep the loan long enough. The best mortgage rates in New Hampshire go to borrowers who shop this way, with their credit and documents ready before the first call.
New Hampshire mortgage companies come in a few kinds: banks and credit unions that lend their own money, mortgage brokers who shop several wholesale lenders, and lenders approved to offer NH Housing's programs. Whichever you choose, each loan officer at NH mortgage companies, banks and credit unions has an NMLS number you can look up on NMLS Consumer Access. We don't recommend one lender over another in print, but our buyers who get a local lender's estimate alongside a national one tend to see which one is competitive quickly.
For a second home or vacation condo in the White Mountains, expect the lender to price it differently from a primary residence, and tell every lender the same occupancy so the estimates are comparable.
When do you pay PMI, and when does it come off?
Private mortgage insurance is required on most conventional loans with less than 20% down, and it does not last forever. Under the federal rules summarized by the Consumer Financial Protection Bureau, you can ask your servicer in writing to cancel PMI when the balance is scheduled to fall to 80% of the home's original value, and the servicer generally must end it when the balance is scheduled to reach 78%, as long as you are current.
"Original value" generally means the lower of the contract price and the appraised value at purchase. To cancel at 80%, you also need a good payment history, no second mortgage, and usually an appraisal showing the value has not dropped. Extra principal payments can get you there sooner.
What NH Housing programs help with the down payment?
New Hampshire Housing, the state's housing finance agency, offers mortgage programs through approved lenders, including down payment and closing cost assistance of up to $15,000, structured as a 0% second mortgage with a 30-year term, according to NH Housing's mortgage programs page. The assistance requires NH Housing's homebuyer education.
NH Housing also offers below-market-rate loans (FHA, VA, USDA Rural Development or conventional) that generally require you not to have owned a home in the past three years, unless you buy in a targeted area or are a qualified veteran, with income and purchase price limits set by town. Its conventional programs allow as little as 3% down (5% for a two- to four-unit home). Limits change, so check the current figures with NH Housing or an approved lender before you count on a program.
What NH costs does a mortgage calculator leave out?
A mortgage calculator shows the monthly payment, but a New Hampshire purchase also has one-time costs at closing and a few ongoing costs the payment does not capture. The ones we flag for buyers:
- Transfer tax. $0.75 per $100 of the price from the buyer and the same from the seller under RSA 78-B, each rounded to the whole dollar.
- Escrow cushion. Lenders usually collect a few months of tax and insurance at closing to seed the escrow account.
- Village district or HOA costs. A district rate is part of the tax bill; HOA dues are separate and can include roads, plowing or amenities.
- Well, septic and heating. Many homes around Plymouth and Campton run on a private well, a septic system and oil or propane heat, none of which shows up in PITI.
What you do not pay is just as important to the budget. New Hampshire has no income tax on wages and no general sales tax, as our guide to New Hampshire taxes explained covers. For the full background on how town rates are built and why assessments differ from prices, see New Hampshire property taxes explained, and when you are ready to plan a purchase, our buyer services page explains how we work with buyers.
Frequently asked questions
How do I calculate my mortgage payment in New Hampshire?
Use the amortization formula for principal and interest, then add property tax, insurance, any PMI and any HOA fee. Property tax is the town's 2025 NH DRA rate × the assessed value ÷ 1,000, divided by 12. A $360,000 loan at 7.24% for 30 years is $2,453.39 a month in principal and interest before those additions.
What are mortgage rates in New Hampshire?
New Hampshire mortgage rates follow the national market. As of October 29, 2026, Freddie Mac's weekly survey put the U.S. average 30-year fixed rate at 7.24% and the 15-year at 6.60%; Freddie Mac updates the figure every Thursday at freddiemac.com/pmms. Your own rate depends on credit, down payment, loan type, points and the property, so use a written Loan Estimate, not an average.
Does my NH mortgage payment include property taxes?
Usually, yes. Most lenders collect one-twelfth of the annual property tax and homeowners insurance with each payment, hold it in escrow and pay the bills when due. Because NH towns set new rates each fall, the escrow amount is often adjusted after the first December tax bill.
How much is property tax on a $450,000 house in NH?
It depends on the town and the assessment. At 2025 NH DRA rates, a home assessed at $450,000 pays $5,283 a year in Thornton, $7,857 in Campton and $10,696.50 in Plymouth. These are arithmetic examples; the home's tax card and last bill give the real figure.
When can I stop paying PMI?
You can ask in writing to cancel PMI when your balance is scheduled to reach 80% of the home's original value, and the servicer generally must end it at 78%, if you are current on payments (CFPB). Original value is usually the lower of the purchase price and the appraisal.
Do first-time buyers get help in New Hampshire?
Yes. NH Housing offers down payment and closing cost assistance of up to $15,000 as a 0% second mortgage, plus below-market-rate loans that generally require not having owned a home in the past three years. Income and purchase price limits apply, and homebuyer education is required for the assistance.
What closing costs does a buyer pay in New Hampshire?
A New Hampshire buyer pays $0.75 per $100 of the price in transfer tax under RSA 78-B, $3,375 on a $450,000 home, plus lender fees, title insurance, recording fees and prepaid escrow. Our closing cost guide has a calculator for the full cash to close.
