Loan-to-Value Ratio (LTV): The Formula, the Thresholds, and How It Changes Your Rate
Loan-to-value ratio (LTV) is the single number lenders use to price your mortgage risk — it decides whether you pay private mortgage insurance, how high your interest rate lands, and whether you can refinance or open a HELOC at all. The formula is simple: divide the loan amount by the appraised value of the home, then multiply by 100 (CFPB — LTV). The consequences of the number are not. An 80.01% LTV can cost roughly $100–$250 a month in PMI on a $400,000 loan, and every 5-point band above 60% typically adds a loan-level price adjustment under Fannie Mae and Freddie Mac pricing grids. This guide covers the exact 2026 thresholds by loan program, three worked examples, how the appraisal moves LTV in either direction, and what CLTV means when you stack a home equity line on top of a first mortgage.
Key Takeaways
- The formula: LTV = (loan amount ÷ appraised value) × 100. A $360,000 loan on a $400,000 home = 90% LTV (CFPB — LTV).
- The 80% rule: Conventional loans stop requiring private mortgage insurance (PMI) once LTV falls to 80% or below; the federal Homeowners Protection Act requires lenders to auto-terminate PMI at 78% based on the original amortization schedule (CFPB — PMI cancellation).
- Program maximums (2026): Conventional standard 95%, Conventional HomeReady/Home Possible 97%, FHA 96.5% (3.5% down minimum), VA 100% (eligible service members), USDA 100% (eligible rural areas) (Fannie Mae Selling Guide, HUD FHA Handbook 4000.1).
- CLTV includes second liens: Combined loan-to-value adds your first mortgage plus any HELOC, home equity loan, or second mortgage — most lenders cap CLTV at 80–85% for home equity products (Bankrate — HELOC requirements).
- LTV changes your rate, not just your approval: Fannie Mae and Freddie Mac apply loan-level price adjustments (LLPAs) in 5-point LTV bands — a 90% LTV loan can cost 0.5–1.25 points more than a 60% LTV loan at the same credit score (Fannie Mae LLPA matrix, Freddie Mac PMMS).
What loan-to-value ratio (LTV) actually measures
LTV is the share of your home's value that's financed rather than paid in cash. Put a different way: it's the size of your loan expressed as a percentage of what the house is worth. Lenders use it as a risk gauge, because a borrower with 40% equity has a much larger cushion between the loan balance and the sale price than a borrower with 3% equity.
That risk framing is why LTV controls so many downstream costs. The lender uses it to decide whether to require mortgage insurance, to set the interest rate through pricing adjustments, and to cap how much they'll lend against the property in the first place. Two borrowers with identical credit scores and incomes can be quoted noticeably different rates purely because one is putting 20% down and the other 5%.
One thing LTV is not: an underwriting shortcut. Approval also depends on debt-to-income ratio, credit history, reserves, property type, and occupancy. Confirm your specific LTV thresholds and pricing with your lender or loan officer before making a down payment decision — the numbers below are current program benchmarks, not a personalized quote.
The LTV formula, with three worked examples
The formula is one line: LTV = loan amount ÷ appraised value × 100. The appraised value is the number the lender uses, which is usually the lesser of the appraisal or the purchase price on a home purchase, or the appraised value on a refinance. Because the calculation is sensitive to that denominator, an appraisal that comes in low can move your LTV even when nothing else changes.
Here are three scenarios that cover most of the questions people bring to LTV.
| Scenario | Home value | Loan amount | LTV | Notes |
|---|---|---|---|---|
| Purchase, 10% down | $400,000 | $360,000 | 90% | PMI required on conventional until LTV drops to 80% |
| Rate-and-term refinance | $500,000 | $325,000 | 65% | Below the 80% PMI threshold; strong LLPA pricing |
| Cash-out refinance | $500,000 | $400,000 | 80% | At the Fannie Mae cash-out cap for a primary residence |
The first row is a first-time buyer scenario — the borrower comes in with $40,000, the lender finances the rest, PMI is required because LTV is above 80%. The second row is a homeowner who has paid down principal and gained appraised value; they're a low-risk refi. The third row is that same homeowner tapping equity for a large expense — the loan grows to $400,000, LTV lands right at 80%, which is the standard cap on a conventional cash-out refi for a primary residence.
LTV by loan program in 2026
Different loan programs cap LTV at different levels because the entities backing them accept different risk. Confirm your specific eligibility with your lender — program guidelines are updated regularly, and overlays vary by lender. The table below reflects current program maximums as of 2026.
| Loan program | Maximum LTV | Down payment | Source |
|---|---|---|---|
| Conventional (Fannie Mae Standard) | 95% | 5% | Fannie Mae Selling Guide |
| Conventional HomeReady / Home Possible | 97% | 3% | Fannie Mae Selling Guide, Freddie Mac Home Possible |
| FHA | 96.5% | 3.5% | HUD FHA Handbook 4000.1 |
| VA | 100% | 0% | VA Lenders Handbook M26-7 |
| USDA Rural Development | 100% | 0% | USDA 3555 Handbook |
| Jumbo (non-conforming) | 80–90% (lender-dependent) | 10–20% | Lender guidelines vary |
| HELOC / Home Equity Loan | 80–85% CLTV | Equity requirement, not down payment | Bankrate — HELOC requirements |
Two program notes worth flagging. Conventional 97% products (HomeReady and Home Possible) come with income limits and, usually, a homebuyer education requirement — they're not open to every borrower. FHA at 96.5% requires mortgage insurance premium (MIP) that, for most 2026 originations, stays in place for the life of the loan unless you refinance out, unlike conventional PMI which drops off automatically.
What counts as a "good" LTV in 2026
At or below 80% is the practical target for most borrowers, because that's where PMI stops on conventional loans and where lender pricing turns favorable. At 60% or below, LLPAs drop to their lowest tier, and refinance offers get noticeably cheaper. Above 95%, you're eligible for financing but paying meaningfully more per month for the same house.
The trade-off is real: a low LTV means you're using cash today that could be an emergency fund, a renovation budget, or investment savings. A high LTV means you keep that cash but pay more monthly for as long as the LTV stays elevated. Neither is universally correct.
- Below 60%: Best LLPA pricing, no PMI, easiest approval, strongest refi terms.
- 60.01–80%: Standard pricing, no PMI on conventional, still strong LLPA treatment.
- 80.01–90%: PMI required (conventional) or MIP (FHA); moderate LLPA rate hit.
- 90.01–95%: PMI plus a larger LLPA; approvable but the monthly cost is meaningfully higher.
- 95.01–97%: Limited to first-time buyer programs (HomeReady, Home Possible) with education requirements; highest LLPAs on the conventional grid.
- Above 100%: Underwater — refinancing and HELOC options are typically unavailable, and selling requires bringing cash to closing.
A useful anchor is your monthly payment target. If a 10% down payment (90% LTV) blows past what you can comfortably carry once PMI and LLPAs are baked in, the "good LTV" for you is closer to 80% — even though 90% is fully approvable.
The 80% threshold — where PMI stops
For conventional loans, PMI is required when LTV starts above 80% and drops off in two ways. You can request cancellation once you reach 80% LTV based on the original amortization schedule or a current appraisal or broker price opinion. Lenders are also required by federal law to auto-terminate PMI at 78% LTV based on the original amortization schedule under the Homeowners Protection Act (CFPB — PMI cancellation).
Two practical implications. First, if your home has appreciated meaningfully, you can often drop PMI faster than the amortization schedule would suggest by paying for a lender-ordered appraisal to prove current LTV is 80% or below. Second, on an FHA loan the equivalent — MIP — behaves differently: for most 2026 originations, MIP remains in place for the life of the loan when you put less than 10% down. Refinancing into a conventional loan once LTV crosses 80% is a common way FHA borrowers remove MIP.
On a $400,000 loan, PMI typically costs $100–$250 per month depending on credit score and provider (CFPB — PMI cancellation). Rates vary by insurer and by borrower profile; specific costs are on your Loan Estimate. Because PMI is priced against LTV, dropping five points can noticeably lower the monthly payment on a marginal file.
How LTV moves your rate (LLPAs explained)
Fannie Mae and Freddie Mac publish loan-level price adjustment (LLPA) matrices that price each 5-point LTV band against the borrower's credit score. On a 720+ FICO conventional loan, the pattern looks roughly like this: 60% LTV = 0 LLPA, 75% LTV = ~0.375 LLPA, 85% LTV = ~0.75 LLPA, 95% LTV = ~1.125 LLPA. Each 0.375 LLPA translates to roughly 0.125% on the note rate depending on market conditions (Fannie Mae LLPA matrix).
Those numbers are representative — check the current matrix before quoting them. The LLPA grid was revised in 2023 and again in 2025, so any single snapshot goes stale quickly. What doesn't change is the shape: lower LTV means lower LLPA means lower rate. Freddie Mac's Primary Mortgage Market Survey publishes the average 30-year fixed rate that reflects these adjustments across the market each week.
This is why understanding how loan-level price adjustments work matters even for borrowers who aren't rate-shopping intensively. Two applicants with the same 720 FICO and the same home purchase price can be quoted rates 0.375–0.5% apart purely because one puts 20% down and the other 10%. Over a 30-year term, that gap is tens of thousands of dollars.
CLTV — how second liens change the math
Combined loan-to-value (CLTV) adds your first mortgage balance plus any second lien — a HELOC, home equity loan, or piggyback second — and divides by the appraised value. Most HELOC and home equity loan lenders cap CLTV at 80–85% (Bankrate — HELOC requirements). That cap is the constraint on how much you can actually borrow against a home.
A worked example: on a $500,000 home with a $300,000 first mortgage, your first-mortgage LTV is 60%. At an 85% CLTV cap, the lender allows total secured debt up to $425,000, which means you can borrow up to $125,000 in second-lien debt. At an 80% CLTV cap, total secured debt tops out at $400,000, so you can borrow up to $100,000. The 5-point cap difference is worth $25,000 of borrowing capacity.
| Component | Amount | Ratio |
|---|---|---|
| Home appraised value | $500,000 | — |
| First mortgage balance | $300,000 | 60% LTV |
| Available at 80% CLTV cap | $100,000 second-lien capacity | 80% CLTV |
| Available at 85% CLTV cap | $125,000 second-lien capacity | 85% CLTV |
CLTV also matters when you're stacking products. Opening a home equity loan or HELOC doesn't change your first-mortgage LTV, but it can push your CLTV to the lender's cap and eliminate room for additional borrowing. Some borrowers who plan to renovate open a HELOC before running the numbers on a home equity loan, only to find they've used the CLTV headroom they needed for the other product.
LTV thresholds for refinance
Refinance LTV caps are stricter than purchase caps because the risk profile is different. Under Fannie Mae's Standard product, a rate-and-term refi goes to 95% LTV (97% with HomeReady or Home Possible when the loan being paid off is also a Fannie loan). Cash-out refis cap at 80% LTV for a primary residence and 75% LTV for a two-to-four-unit property (Fannie Mae Selling Guide).
FHA streamline and VA IRRRL are the exceptions. Both waive the appraisal for like-for-like refinances, which means LTV is calculated off the existing loan and property information rather than a new appraised value. FHA cash-out caps at 80% LTV as of the 2019 policy change (HUD Mortgagee Letter 2019-11).
The practical implication: if your goal is a cash-out refi to consolidate debt or fund a renovation, model your target LTV before you apply. Pulling $50,000 out on a $500,000 home with a $360,000 first mortgage pushes your loan to $410,000 — an 82% LTV, which is over the conventional cash-out cap. You'd need to either take less cash or find a lender product that goes higher (which comes with its own pricing hit).
When the appraisal moves your LTV (up or down)
Two scenarios shift LTV without any change in what you owe or what you're borrowing. First: on a home purchase, if the appraisal comes in below the purchase price, your LTV is calculated off the appraised value, not the price. You put down the same $40,000 on a $400,000 home; if the appraisal is $380,000, the lender treats the loan as $360,000 ÷ $380,000 = 94.7% LTV, not 90%. That can push you into a higher LLPA band or trigger PMI you didn't plan for.
Second: on a refinance in a rising-value market, your LTV drops without you paying down principal. A borrower with a $325,000 balance who bought when the home appraised at $400,000 (81% LTV) refinances two years later when the home appraises at $475,000 — new LTV is 68%. That equity buildup, based on current market value, can be enough to drop PMI, unlock better LLPA pricing, or make a HELOC accessible for the first time.
Both scenarios argue for checking your current LTV before applying, not after. If the appraisal is likely to come in low on a purchase, negotiate the price down or bring more cash. If your home has appreciated meaningfully, get a current valuation to see whether you've quietly crossed a threshold that changes what's available to you.
What LTV means when you sell — payoff math for sellers
When you sell, LTV stops being about qualification and starts being about payoff math. Your first mortgage and any second lien are paid off at closing from sale proceeds. If the combined payoff plus selling costs exceeds the sale price, you have to bring cash to closing to cover the shortfall.
A worked example: you sell a $500,000 home carrying a $340,000 first mortgage and a $60,000 HELOC — a combined $400,000 of secured debt (80% CLTV). Standard selling costs of about 8–10% run $40,000–$50,000. Net proceeds to you: roughly $50,000–$60,000. If the market softens 5% and the home actually clears at $475,000, that net drops to $25,000–$35,000 before any of it can move to a down payment on your next home.
This is why a high CLTV on the home you're leaving directly shrinks the down payment available for the next one. It's also why sellers who plan to buy again benefit from knowing their CLTV before listing, not after signing an offer. The math is not a surprise if you run it early.
LTV vs LVR — the same idea, different name outside the US
"LVR" (loan-to-value ratio) is the same calculation used in Australia, New Zealand, and the UK. Regulators in India, Canada, and Hong Kong set statutory LVR caps that can be tighter or looser than US program limits — a household in Hong Kong buying a mid-priced home faces a maximum LVR that's noticeably lower than a US first-time buyer using HomeReady. If you're reading UK or Australian mortgage guidance while researching a purchase or a rate structure, LVR = LTV; the math is identical.
Wikipedia's loan-to-value ratio entry collects statutory LVR caps by country if you need a reference. For US borrowing decisions, though, the program-specific thresholds in the table above are the operative numbers.
When a high LTV is the right call — and when it isn't
There's a case for a high-LTV loan and a case against, and they don't cancel each other out. High LTV is the right call when you have a stable income, you're in a market where staying invested (keeping cash liquid) is worth more than the monthly PMI cost, and you plan to stay in the home long enough for principal paydown or appreciation to naturally drop LTV. A first-time buyer using HomeReady at 97% LTV who couldn't otherwise buy is a legitimate use case.
High LTV is the wrong call when the monthly payment leaves no margin, when you'd have to skip building an emergency fund to fit the down payment, or when you're likely to need to move within 24 months — because you haven't yet paid down enough principal to cover selling costs, and a market dip can put you underwater.
Neither answer is universal. The right LTV depends on cash reserves, income stability, time horizon in the home, and the pricing gap between your available LTV bands. Do the math both ways before committing.
