Idaho Jumbo Loan Calculator
Calculator Definitions
• Jumbo loan: A jumbo loan is a mortgage exceeding the conforming loan limits set by the Federal Housing Finance Agency (FHFA), which is $806,500 in most Idaho counties.
• Home price: The home price is the purchase price you’ve agreed upon with the home seller. It affects your estimated monthly mortgage payment, total interest paid, and overall loan cost.
• Down payment: The down payment is the initial amount paid upfront. Jumbo loan requirements can be more strict, and you’ll typically need to put down at least 10% of the home price for this type of mortgage loan.
• Loan term: The loan term is the duration to repay the mortgage, typically 30 or 15 years, though terms of 10 or 20 years are also available. A longer term lowers monthly payments but increases total interest paid while a shorter term saves on interest but increases monthly payments.
• Interest rate: The interest rate is the cost of borrowing, expressed as a percentage of the loan amount.
• Annual property tax: Property tax is levied by local governments on land and buildings. It is typically a percentage of the property’s assessed value, which may differ from its market value.
Here’s how to use the Idaho jumbo loan calculator effectively:
Step 1: Enter Your Home Price

Step 2: Enter Your Down Payment Amount

Step 3: Select a Loan Term
Choose a loan term between 10 and 30 years.
Step 4: Enter Your Interest Rate
Input your anticipated interest rate to the second or third decimal point.
Step 5: Enter Your Property Tax Rate
Enter your annual property tax rate as a percentage. Property taxes in Idaho vary by county. The average property tax rate is 0.55%.
What Are Jumbo Loans and Conforming Loan Limits?
If you are looking to purchase a high-priced home, you will want to figure out what a jumbo loan is. It’s a mortgage that exceeds the conforming loan limits set by the Federal Housing Finance Agency (FHFA). The conforming loan limit in 2025 for a single-family home in most counties in Idaho is $806,500. Teton County has a limit of $1,209,750. For a loan amount above these limits, you will need to seek a jumbo loan.
When comparing jumbo loans vs. conventional loans, jumbo loans often have more stringent qualification criteria. Borrowers generally need a higher credit score (700+) and significant cash reserves to qualify. Lenders also typically require a down payment of 10%, though some look for 20%. Fortunately, private mortgage insurance (PMI) is typically not required for down payments less than 20%.
The Idaho jumbo loan mortgage calculator offers many benefits, especially for first-time homebuyers. It can help you budget by providing an estimate of your monthly mortgage payment, including principal, interest, and property taxes.
To make an informed decision, use the calculator to compare offers from multiple lenders and find the loan that best serves your needs. This tool also shows how changes in interest rates can affect your payments, allowing you to plan for different scenarios.
How to Use the Jumbo Loan Calculator to Compare Scenarios
As you plan to make a new home purchase in Idaho, use the Idaho jumbo loan calculator to compare loan scenarios that meet your budget and financial goals. Here’s the process:
• Modify the home price to see how it affects affordability. Remember that you may qualify for a higher loan amount than you can comfortably afford.
• Consider a larger down payment to reduce your overall interest costs.
• Explore shorter loan terms to save on interest, although that will mean higher monthly payments.
• Enter different interest rates to explore the implications of an adjustable-rate loan.
• Use the calculator to evaluate how minor rate changes could affect a jumbo loan.

Deciding How Much House You Can Afford in Idaho
To help you determine how much house you can afford in Idaho, you can use the guideline that housing costs shouldn’t exceed 28% of your gross monthly income. If you are looking to purchase a $1 million home in Idaho with a 10% down payment ($100,000), a 30-year term, and 6.75% interest rate, your monthly payment would be $5,837, excluding taxes and insurance. You would need to earn an annual income of around $250,000 to comfortably afford that payment, assuming no other debts.
Additionally, lenders suggest your total debt payments be less than 36% of your gross monthly income; other debt shouldn’t exceed about $1,600 monthly in this case. If you want to factor in other debts, such as a car loan, student loan, or credit card payment, you can use a home affordability calculator.
A more reliable method to help you determine affordability is to go through the mortgage preapproval process with a lender, where you provide detailed financial information. The lender will let you know whether you qualify for a loan and, if so, in what amount and under what terms.
Even though there are different types of mortgage loans, the core elements of any mortgage payment remain the same: the principal and interest. The Idaho jumbo loan calculator also includes annual property tax, which may be part of your monthly payment.
Other financial obligations that may be rolled into your mortgage bill are homeowners insurance and homeowners association (HOA) dues. Understanding these components helps you get a more accurate picture of your total commitment, ensuring you are well-prepared for the financial responsibilities of homeownership.

Cost of Living in Idaho
As you set your sights on purchasing a home in Idaho, it’s a good idea to research the cost of living to help you determine how far your dollar goes. Places with a higher cost of living typically have more expensive home prices along with higher expenses for utilities, maintenance, and transportation.
With a cost of living index of 99.9, Idaho is right in line with the national average. Housing costs (also 99.9) are average, while utilities (75.1) are about 25% cheaper.
Tips on Reducing Your Jumbo Loan Payment
Homebuyers looking to trim their monthly payment can explore a variety of tips:
• Shop around for less expensive homeowners insurance, opt for a higher deductible, or combine policies to secure a discount.
• Extend the term of your loan to reduce monthly payments, though this increases the total interest you’ll pay.
• If you face financial hardship in the future, talk to your lender about a loan modification.
As you consider a jumbo mortgage loan in Idaho, use a jumbo loan calculator to estimate your monthly payments and total costs. This tool can help you experiment with different down payment amounts, various interest rates, and loan term options so you can make the right financial decision for your budget. By being proactive, you can be better prepared to locate and pay for the home of your dreams.
When you’re ready to take the next step, consider what SoFi Home Loans have to offer. Jumbo loans are offered with competitive interest rates, no private mortgage insurance, and down payments as low as 10%.

Jumbo loans offer several benefits, including the ability to finance high-value properties and gain access to certain interest rates. Despite the fact that they can be higher risk for a lender, jumbo loans can have competitive rates in favorable markets.
How much are closing costs on a jumbo loan?
Closing costs for a jumbo loan in Idaho typically range from 2% to 5% of the property’s price. For a $1 million home, this translates to an estimated expense of $20,000 to $50,000.
What credit score is needed for a jumbo loan?
A credit score of 700 or higher is required to secure a jumbo loan (it’s 620 for a conventional conforming mortgage), although some lenders prefer 720. Jumbo loans have stricter criteria, including a low debt-to-income ratio and significant cash reserves. To increase your chances of approval, work on improving your credit score by paying down credit card debt and higher-interest loans.
Is $900,000 a jumbo loan?
Yes, a $900,000 mortgage is typically classified as a jumbo loan in most parts of the U.S. In 2025, the conforming loan limit for a single-family home is $806,500. This limit is higher in designated high-cost areas.
