What is the jumbo loan limit in 2024?

The standard conforming loan limit for 2024 is $766,550 for a single-family home in most U.S. counties. High-cost areas — such as parts of California, New York, Colorado, and Hawaii — have limits up to $1,149,825. Any loan amount above the applicable limit for your county is classified as jumbo. This calculator uses the baseline $766,550 figure; check the FHFA website for your county's specific limit before assuming a loan is or isn't jumbo.

Do jumbo loans require 20% down?

Not always, but 20% is the most common requirement. Some jumbo lenders allow 10–15% down, particularly for borrowers with high credit scores and substantial liquid reserves. However, going below 20% on a jumbo loan often results in a higher interest rate, stricter income requirements, or a requirement to hold additional cash reserves post-closing. Unlike conventional loans, PMI is rarely available on jumbo loans — lenders price the additional risk into the rate instead.

How does DTI work for jumbo loans?

Debt-to-income ratio (DTI) is the percentage of your gross monthly income consumed by all required debt payments, including the new housing payment. For conventional loans, lenders may approve up to 45–50% DTI with compensating factors. Jumbo lenders are stricter: most cap total DTI at 43%, and many prefer borrowers to stay at or below 36–38%. Exceeding 43% will result in a denial at most institutions, though a handful of portfolio lenders go to 45% for borrowers with exceptional reserves, credit scores above 780, or down payments of 30% or more.

Why does property tax affect how much I can borrow?

Property tax is calculated as a percentage of home value, so it scales directly with the purchase price. On a $2 million home with a 1.2% tax rate, annual property taxes are $24,000 — or $2,000 per month. That full $2,000 counts toward your DTI alongside principal, interest, and insurance. Buyers who focus only on the interest rate often underestimate how much property taxes reduce their maximum affordable price. The higher the tax rate in your area, the more it compresses your borrowing capacity.

What credit score do I need for a jumbo loan?

Most jumbo lenders require a minimum credit score of 700–720. Better rates are available at 740–760+, and some lenders require 740 as a minimum for larger loan amounts (above $2 million). Unlike FHA or VA loans, there is no government backing on jumbo loans, so lenders set their own credit score floors. A higher score can help offset a DTI that is near the limit. In addition to credit score, jumbo lenders scrutinize asset documentation closely — expect to document 6–18 months of PITI payments in liquid reserves.

Jumbo Loan Affordability Calculator

Find your maximum jumbo loan home price based on income and DTI limits, then check any target price to see if it qualifies.

By The FinCalc TeamUpdated May 23, 2026

A jumbo loan is any mortgage that exceeds the conforming loan limit — $766,550 for most U.S. counties in 2024. Because Fannie Mae and Freddie Mac cannot purchase jumbo loans, lenders hold them on their own books and apply stricter standards: total debt-to-income typically capped at 43%, down payments of 10–20% or more, and stronger reserve requirements. This calculator uses your income and monthly debts to find the maximum home price you can afford at both the conservative 36% DTI threshold and the standard jumbo lender limit of 43%, then lets you check any target price to see your exact DTI and whether the loan would be classified as jumbo.

How This Calculator Works

Step 1: Monthly Income

Monthly gross income = annual income ÷ 12. All DTI ratios are calculated against this figure.

Step 2: Housing Budgets at Each DTI Threshold

Max monthly housing (36%) = monthly income × 0.36 − existing monthly debts
Max monthly housing (43%) = monthly income × 0.43 − existing monthly debts

The result is the maximum you can spend on principal, interest, property tax, and insurance combined at each threshold.

Step 3: Back-Solving for Home Price

Given a monthly housing budget, the calculator solves directly for the maximum home price:

Home Price ≤ (budget − insurance) ÷ [(1 − down%) × mf + taxRate ÷ 12]

Where mf is the standard amortization factor (monthly payment per dollar of loan). Because property tax scales linearly with price, the algebra remains closed-form — no iteration needed.

Step 4: Target Price Analysis

When you enter a specific home price, the calculator computes:

Loan amount = home price × (1 − down payment %)
Monthly P&I using the amortization formula
Monthly tax = home price × tax rate ÷ 12
Total housing = P&I + tax + insurance
Total DTI = (housing + existing debts) ÷ monthly income
Jumbo status = loan amount > $766,550

When to Use This Calculator

1. Setting Your Search Price Range

Before browsing listings or talking to a real estate agent, use this calculator to establish a realistic ceiling — not what you're approved for in principle, but what keeps your DTI within lender limits given your existing debts and the property taxes typical in your target area. Knowing the 36% and 43% numbers together shows you both the "comfortable" and the "maximum approved" price bands.

2. Pressure-Testing a Specific Listing

Found a home you want to make an offer on? Enter the listing price in the target section to see the exact DTI it produces. If it comes in above 43%, you'll know before wasting time on a pre-approval that will be denied.

3. Understanding the Impact of a Larger Down Payment

Increase the down payment percentage and watch both the maximum affordable price and the target DTI shift. A larger down payment reduces the loan balance, which lowers the P&I payment and therefore the DTI. This helps you model the trade-off between preserving cash reserves (which lenders also require) and putting more down to qualify for a higher-priced home.

4. Comparing the Conservative vs. Aggressive Budget

The 36% DTI output represents what most financial planners consider sustainable long-term — leaving room for savings, emergencies, and lifestyle costs. The 43% output represents the lender's maximum. The gap between them is your margin of safety. If the home you want is above the 36% price but below the 43% price, you can qualify, but you're borrowing near the limit — worth knowing in advance.

Understanding the Inputs

Annual Gross Income: Your total gross (pre-tax) income from all sources — salary, bonuses, self-employment net profit, rental income, and so on — stated annually. Jumbo lenders typically require two years of documented income history and may average variable components (bonuses, commissions) over that period.
Monthly Debt Payments: The total of all required monthly debt payments: car loans, student loans, credit card minimum payments, any other mortgage payments, personal loans, and alimony or child support obligations. Do not include utilities, groceries, or subscriptions. These payments count toward your DTI alongside housing costs.
Down Payment: The percentage of the home price you will pay upfront. Jumbo lenders commonly require 10–20% minimum; some require 20–30% for higher loan amounts (above $2 million). Unlike conventional loans, most jumbo loans do not offer PMI — a larger down payment directly reduces your loan balance and monthly payment.
Interest Rate: Your expected jumbo loan interest rate. Jumbo rates typically run 0.25–0.50% above comparable conforming rates, though the spread narrows in competitive markets. Always get quotes from multiple jumbo lenders; rates vary significantly by institution and loan size.
Loan Term: The length of the mortgage — 30 years is most common for jumbo loans, though 15-year terms are available at lower rates. A shorter term increases the monthly payment but reduces total interest and builds equity faster.
Annual Property Tax Rate: Your estimated property tax as a percentage of the home's value. This varies widely by state and county — from under 0.5% in Hawaii to over 2% in Illinois or New Jersey. Because tax scales with the home price, this directly affects how much house you can afford at a given DTI.
Monthly Homeowners Insurance: Your estimated monthly homeowners insurance premium. For high-value homes, a rough estimate is $100–$200 per month for every $1 million in dwelling coverage, though actual premiums vary by location, coverage level, and insurer.
Target Home Price: An optional specific price you want to check. The calculator computes the exact monthly payment, total DTI, and whether the resulting loan would be classified as jumbo — helping you confirm whether a particular home fits within lender guidelines before making an offer.
