How to Use This Calculator

This LTV calculator requires just two required inputs and one optional field. It produces your current LTV, equity position, maximum cash-out availability at different LTV thresholds, and program eligibility.

  1. Current Home Value — Enter your best estimate of your home's current market value. You can use a recent comparable sale, an online estimate from Zillow or Redfin, or the appraised value from a recent transaction. Note that online estimates can vary by 5%–10% from actual appraisals, so treat this as an estimate rather than a definitive figure.
  2. Current Loan Balance — Find this on your most recent mortgage statement. This is your outstanding principal — what you still owe, not your original loan amount. If you have a second mortgage or HELOC, include it if you want to calculate your Combined LTV (CLTV).
  3. Cash-Out Amount (optional) — If you are considering a cash-out refinance, enter the dollar amount you want to take out. The calculator will show your new LTV after the cash-out and whether you remain eligible for conventional cash-out programs (which generally cap at 80% LTV).

After clicking "Calculate LTV," you'll see your current LTV percentage with a status indicator, your equity in dollars and as a percentage, the maximum cash-out available at 80%, 90%, and 97% LTV thresholds, and which major loan programs you're currently eligible for based on LTV alone.

What Is Loan-to-Value Ratio and Why Does It Matter?

Loan-to-value ratio (LTV) is expressed as a percentage: your outstanding loan balance divided by your home's current market value. It is one of the most important metrics in mortgage lending, used by lenders to measure risk, determine rate pricing, set PMI requirements, and establish program eligibility. A lower LTV means more equity, less risk for the lender, better rates for you, and no PMI requirement on conventional loans at or below 80%.

LTV affects nearly every aspect of your refinance. If your LTV is 75%, you get access to the best conventional rate tiers and face no PMI. If it's 85%, you'll pay PMI and face slight rate adjustments. If it's above 97%, most conventional programs are unavailable. Understanding your exact LTV before shopping for a refinance helps you know what to expect in terms of rate, program, and PMI cost.

How LTV Is Calculated

LTV = (Loan Balance ÷ Home Value) × 100
Example: $330,000 ÷ $450,000 × 100 = 73.3% LTV

Key LTV Thresholds for Refinancing

Real-World Example

Rachel's LTV Calculation and Cash-Out Analysis

Rachel bought her home in 2019 for $420,000 with a $399,000 loan (95% LTV). Over five years of payments at 4.5%, her balance is now $362,000. Thanks to strong market appreciation, her home is now worth $530,000.

Current LTV: $362,000 ÷ $530,000 = 68.3%
Current equity: $530,000 − $362,000 = $168,000 (31.7%)
Maximum cash-out at 80% LTV: ($530,000 × 0.80) − $362,000 = $424,000 − $362,000 = $62,000 available

Rachel started at 95% LTV with PMI. She is now at 68.3% — well below the 80% threshold. She can refinance without PMI, potentially access $62,000 in cash for home improvements, and lock in a new rate that may be lower than her current 4.5% (depending on current market rates). Her LTV journey from 95% to 68% happened through a combination of principal paydown (amortization) and home appreciation working together.

How LTV Changes Over Time

Your LTV is not static — it changes with every mortgage payment you make and every shift in your home's market value. Understanding what drives LTV change helps you plan refinancing and PMI removal strategically.

Forces That Reduce LTV (Build Equity)

  • Regular principal paydown (amortization). Every monthly payment reduces your balance slightly. In the early years of a 30-year mortgage, this reduction is slow — most of each payment goes to interest. Equity build-through-amortization accelerates in the later years as the interest portion shrinks.
  • Home appreciation. When your home increases in value, your LTV drops automatically — even if your balance hasn't changed. A home that appreciates 5% per year can drop your LTV by several percentage points annually if your balance is growing slowly.
  • Extra principal payments. Any payment above the required amount goes directly toward reducing the principal balance, accelerating equity buildup and driving down LTV faster than the standard amortization schedule.
  • Home improvements. Renovations — particularly kitchen and bathroom upgrades, additions, and curb appeal improvements — can increase your home's appraised value, reducing LTV.

Forces That Increase LTV (Erode Equity)

  • Cash-out refinance. Taking cash out increases your loan balance, directly increasing your LTV. Conventional cash-out is typically capped at 80% LTV.
  • Home value decline. A falling market reduces your home's appraised value, which increases your LTV even if your balance hasn't changed. Significant value drops can push LTV above key thresholds like 80% or 97%.
  • Adding a HELOC or second mortgage. Second liens add to your total debt secured by the property. Lenders calculate Combined LTV (CLTV) when evaluating refinance eligibility.

LTV Milestones to Know

Different LTV levels unlock different advantages. Knowing these thresholds helps you time your refinance for maximum benefit.

60% LTV

Best conventional pricing tier. Lenders offer their most competitive rates to borrowers with 40%+ equity. No PMI, no rate adjustments.

75% LTV

Excellent pricing. Most pricing adjustments are minimal at this level. Well below PMI threshold with comfortable equity cushion.

80% LTV

The critical PMI threshold. At exactly 80%, no PMI is required on conventional loans. Refinancing to hit this level is a common and worthwhile goal.

90% LTV

FHA standard limit for most programs. PMI still required on conventional loans. Cash-out options are limited at this level.

95–97% LTV

High LTV conventional available with PMI, but rate adjustments are significant. FHA remains accessible. No cash-out at this level.

100% LTV

VA loans only for eligible veterans. No mortgage insurance required for VA — a significant advantage. Not available for conventional or FHA refinances.

When Does LTV Matter Most?

Rate-and-Term Refinance

For a standard rate-and-term refinance, LTV determines your PMI requirement and rate pricing tier. Every 5–10% LTV improvement can unlock meaningfully better pricing. If you're at 85% LTV, a home appreciation-driven appraisal that pushes you to 79% could eliminate PMI and lower your rate simultaneously. Use the Rate-and-Term Refinance Calculator alongside this one.

Cash-Out Refinance

For cash-out refinancing, LTV is the primary limiting factor. Conventional lenders generally cap cash-out at 80% LTV — you must retain at least 20% equity after taking cash out. If your current LTV is 65%, you can potentially access up to 15% of your home's value (up to the 80% cap) in cash. Use the Cash-Out Refinance Calculator to model the new payment after taking cash out.

PMI Removal

LTV is the central metric for PMI eligibility. Once your LTV drops below 80% (based on current appraised value), you can request PMI cancellation or ensure it's not required on a new loan. Use the PMI Removal Calculator to see how much you'd save by eliminating PMI through refinancing.

Home Equity Access

LTV determines how much home equity you can access through a HELOC or home equity loan. Most lenders allow CLTV (combined loan-to-value, including all liens) up to 80%–85%. The Home Equity Calculator helps you estimate available equity for these purposes.

Common Scenarios

Scenario 1: Recent Buyer at 95% LTV — How Long to Reach 80%?

Alex bought his home 2 years ago with 5% down at $350,000 ($332,500 loan, 95% LTV). At his current 6.5% rate, his balance has dropped to approximately $322,000. His home is now worth $365,000. Current LTV: 88.2% — still above 80%. To reach 80% LTV, Alex needs his balance to drop to $292,000 ($365,000 × 80%). At his current rate with standard payments, that's approximately 8–9 more years away — but if his home continues appreciating, the timeline shortens considerably. Alex can use this calculator to model different home value scenarios and see when PMI removal becomes feasible.

Scenario 2: Long-Term Homeowner — Is a Cash-Out Viable?

Maria bought 12 years ago for $280,000 with 10% down. Her balance is now $198,000 and her home is worth $480,000. Her LTV is 41.3%. She can access up to $480,000 × 80% − $198,000 = $186,000 in a cash-out refinance while staying under the 80% conventional cap. This is a very comfortable equity position with substantial cash-out flexibility. She uses the Cash-Out Refinance Calculator to evaluate taking $80,000 for a major renovation.

Scenario 3: Underwater Borrower — What Are the Options?

After a market downturn, James's balance is $295,000 on a home worth $270,000 — an LTV of 109.3%. He is underwater. Conventional refinancing is not available. His options are limited to VA IRRRL (if he's a veteran), FHA streamline (if he has an FHA loan), or waiting for the market to recover. He should not refinance into another conventional loan at this LTV. Government programs like HARP (now expired) historically assisted underwater borrowers, but no equivalent program exists currently at this scale.

Tips for Managing and Improving Your LTV

Get an Informal Estimate Before Paying for an Appraisal

Free online tools like Zillow, Redfin, and Realtor.com provide automated valuation model (AVM) estimates that can give you a quick read on your likely LTV. If the informal estimate puts you comfortably below a key threshold (like 78% or 80%), it's worth ordering a formal appraisal. If the informal estimate suggests you're right on the boundary, consider whether the $300–$600 appraisal cost is worth it based on potential PMI savings.

Ask Your Lender About Appraisal Thresholds

If your informal LTV estimate is close to a pricing tier boundary — say, 80.5% — ask your lender what would happen if the appraisal came in at the expected value. A formal appraisal at slightly above the AVM estimate could drop you into a better pricing tier or eliminate PMI entirely. The marginal improvement could easily be worth the appraisal fee.

Understand CLTV for HELOCs and Second Mortgages

Combined LTV (CLTV) includes all loans secured by your property — first mortgage, second mortgage, HELOC, etc. When applying for a refinance or HELOC, lenders evaluate CLTV, not just your first mortgage LTV. If you have a $300,000 first mortgage and a $40,000 HELOC on a $450,000 home, your CLTV is ($300,000 + $40,000) ÷ $450,000 = 75.6% — not the 66.7% of the first mortgage alone.

Use Current Value, Not Purchase Price, for Refinancing

For refinancing purposes, your LTV is based on current appraised value, not what you paid for the house. Many borrowers who bought at a higher LTV several years ago have seen their LTV drop dramatically through a combination of appreciation and paydown. Always use current market value when modeling your LTV for a refinance — it may open opportunities you thought were years away.

Frequently Asked Questions

What is loan-to-value (LTV) ratio? +
LTV is your outstanding loan balance divided by your home's current appraised value, expressed as a percentage. An 80% LTV means you owe 80% of the home's value and have 20% equity. Lenders use LTV to assess risk: higher LTV means less equity cushion, which translates to higher risk — and often higher rates or insurance requirements. LTV is recalculated at closing using a fresh appraisal, which can work in your favor if your home has appreciated since purchase.
How is home value determined for LTV in a refinance? +
In a refinance, a licensed appraiser (ordered and paid by the lender, but at your cost) conducts a full appraisal of your home. The appraiser visits the property, evaluates its condition, and compares it to recent sales of similar properties in your area (called comparables or comps). The resulting appraised value is what the lender uses to calculate your LTV. In some cases, lenders may accept a drive-by appraisal or automated valuation for low-risk transactions, but a full appraisal is most common for refinances.
What if my appraisal comes in lower than expected? +
A low appraisal increases your LTV, which can affect your rate, PMI requirement, and program eligibility. If the appraisal is unexpectedly low, you have several options: review the appraisal for errors (incorrect square footage, missed features, inappropriate comps) and request a reconsideration of value; pay down your loan balance to reach the needed LTV threshold; wait for your balance to naturally amortize further; or shop for a different lender whose appraisal process may use different comps. You can also dispute the appraisal, though this rarely results in large changes.
What is the difference between LTV and CLTV? +
LTV (loan-to-value) typically refers to your primary mortgage balance divided by home value. CLTV (combined loan-to-value) adds up all liens secured by the property — first mortgage, second mortgage, HELOC, and any other recorded liens — and divides by home value. When evaluating a refinance or HELOC application, lenders use CLTV to assess total risk exposure. For example, if you have a $250,000 first mortgage and a $50,000 HELOC on a $400,000 home, your LTV is 62.5% but your CLTV is 75%. The CLTV is what matters for program and PMI eligibility purposes.
What LTV do I need for a conventional refinance? +
Most conventional rate/term refinances allow up to 97% LTV through Fannie Mae and Freddie Mac programs. However, for cash-out refinances, the conventional cap is typically 80% LTV — meaning you must retain at least 20% equity after taking cash out. Going below 80% LTV on a rate/term refi eliminates the PMI requirement entirely. The best pricing tiers are available at 60%, 70%, and 75% LTV breakpoints, so higher equity translates directly to better rates and lower costs.
How does appreciation affect my LTV? +
When your home increases in value, your LTV decreases automatically — even if your loan balance hasn't changed. For example, if you owe $320,000 and your home was worth $380,000 when you bought it (84.2% LTV), but is now appraised at $420,000, your LTV is now 76.2% — below the 80% PMI threshold. This is why ordering a new appraisal at closing can unlock significantly better loan terms if your market has appreciated since you purchased.
Can I refinance with high LTV? +
Yes. Several programs accommodate high LTV refinancing. FHA streamline refinances allow refinancing above 80% LTV with mortgage insurance premium (MIP) instead of PMI. VA loans allow up to 100% LTV for eligible veterans with no mortgage insurance at all. USDA streamline refinances also exist for rural borrowers. If your LTV is above 97% (underwater), options become much more limited, though some lenders offer specialized programs in certain market conditions. Government programs have historically assisted underwater borrowers during housing downturns.
What is the highest LTV for a cash-out refinance? +
For conventional cash-out refinances through Fannie Mae or Freddie Mac, the maximum LTV is generally 80%. This means you must retain at least 20% equity after the cash-out. VA cash-out refinances allow up to 100% LTV for eligible veterans. FHA cash-out refinances allow up to 80% LTV as well. Some portfolio lenders and non-QM programs offer cash-out at higher LTVs (up to 85%–90%), but these typically come with higher rates and stricter qualification requirements. The lower your LTV after cash-out, the better your rate and terms will be.
