Does this include HELOC draw periods?

No. This tool is focused on traditional fixed-rate home equity loans with a lump-sum disbursement and fully amortizing payments from day one. If you are considering a home equity line of credit (HELOC) with an interest-only draw period and a separate repayment phase, use a HELOC-specific calculator that can model those two phases and potential rate changes.

Will I qualify if I’m below the max loan?

Not automatically. Being under the maximum loan-by-LTV limit is only one of several factors lenders consider. They also underwrite your credit history, income stability, debt-to-income (DTI) ratio, property type, and appraisal results. This calculator simply shows whether your scenario fits within a chosen CLTV; actual approval depends on your full application and the lender’s underwriting standards.

What about fees or points?

Many lenders charge origination, underwriting, recording, or appraisal fees, and some offer discount points you can pay up front to reduce the interest rate. Those costs are not included in this calculator’s payment or interest figures. To understand the true cost, ask each lender for an itemized estimate of fees and consider how they affect your total borrowing cost and APR.

Private mortgage insurance (PMI) typically attaches to first mortgages that exceed certain LTV thresholds, not to second-position home equity loans. However, home equity products have their own pricing and fee structures. This calculator does not add PMI or other insurance charges; it strictly models principal, interest, and combined LTV. Your lender can explain any required insurance or additional fees.

Yes. Your maximum loan and combined LTV are only as accurate as the home value you use. If the appraisal comes in lower than expected, the lender will recalculate CLTV using that value, which can shrink your maximum loan or require a lower approved amount. Using conservative values and running a lower-value scenario can help you understand this risk before you apply.

Overview

A home equity loan lets you turn part of your home’s value into a fixed-rate lump sum, but lenders limit how far they’ll let your combined loan-to-value (CLTV) go. This calculator helps you translate your home value, existing mortgage balance, and lender LTV cap into a maximum available loan amount, then shows the monthly payment, total interest, and combined LTV if you borrow that amount or a smaller requested figure.

Use it as a pre-screening tool before you talk to lenders or pay for an appraisal. By experimenting with different home values, LTV limits, APRs, and terms, you can see whether a home equity loan fits comfortably in your budget, how much equity you’d still have after borrowing, and how sensitive your payment is to rate and term choices.

How to use this calculator

Enter your best estimate of the home’s current market value and your latest mortgage payoff balance from a recent statement or your servicer’s online portal.
Enter the lender’s maximum combined LTV limit (or a conservative value such as 80–85%), then enter the amount you’d like to borrow along with an estimated APR and repayment term in years.
Review the calculated maximum loan by LTV, the approved loan amount, the estimated monthly payment, total interest cost, and the combined LTV after borrowing. Adjust the requested amount, APR, or term until the payment and CLTV fit comfortably within your budget and risk tolerance.

Inputs explained

Home value: Estimated market value of the property.
Mortgage balance: Current payoff balance on your first mortgage.
LTV limit: Lender’s max combined LTV (often 80–90%).
Requested loan: Amount you want to borrow; capped at max allowed.
APR: Annual percentage rate for the home equity loan.
Term: Repayment term in years for the loan.

How it works

First, the calculator estimates your maximum loan amount based on your home’s value and the lender’s combined loan-to-value (CLTV) limit. Max loan = (Home value × LTV limit) − existing mortgage balance; if this figure is negative, it means you may not have tappable equity under that LTV cap.

Next, it compares the amount you’d like to borrow to that maximum. The approved loan is set to the smaller of your requested amount and the max loan by LTV. That approved amount is then treated as a standard fixed-rate home equity loan, and the calculator uses your APR and term to compute a fully amortizing monthly payment, total paid, and total interest over the life of the loan.

Finally, the tool adds your current mortgage balance and the approved home equity loan together and divides by the home’s value to show your combined LTV. This percentage is what most lenders focus on when applying their LTV rules and helps you see how much equity cushion you are leaving in the property after borrowing.

Formula

Max loan = (Home value × LTV limit) − Mortgage balance
Approved loan = min(Requested, Max)
Monthly rate = APR ÷ 12
Payments = Term × 12
Payment = P × r(1+r)^n / [(1+r)^n − 1]
Combined LTV = (Mortgage balance + Approved loan) ÷ Home value

When to use it

Checking how much home equity you can realistically access before you apply or pay for a full appraisal, so you avoid asking for far more than lenders are likely to approve under their CLTV guidelines.
Comparing multiple use cases—for example, a smaller project-focused loan versus a larger debt-consolidation loan—by changing the requested amount, term, and APR to see how your payment, total interest cost, and remaining equity change.
Ensuring your combined LTV stays within both lender limits and your own comfort zone before moving forward with renovations, debt consolidation, or other major plans that depend on tapping your home’s equity.

Tips & cautions

Use conservative home value estimates—such as slightly below recent comparable sales—to avoid overestimating your eligibility. A low appraisal can easily shrink your maximum loan, especially near higher LTV caps.
Test both shorter and longer terms. Shorter terms raise the payment but can dramatically reduce total interest paid, while longer terms lower the monthly payment but keep the debt on your books for many more years.
If you are close to the lender’s stated LTV cap, leave a little headroom for appraisal variability and lender overlays. Targeting a slightly lower CLTV than the maximum can make approval smoother and reduce risk.
Does not include lender-specific fees, points, closing costs, or mortgage insurance premiums—add those separately when comparing all-in costs between lenders or against alternatives like personal loans or HELOCs.
Assumes a simple fixed-rate, fully amortizing home equity loan; it does not model draw periods, variable rates, balloons, or hybrid products that blend line-of-credit features with installment repayment.
Eligibility ultimately depends on full underwriting—including credit, income, debt-to-income (DTI) ratios, and appraisal results—so this calculator should be treated as a math estimate only, not a guarantee of approval or specific loan terms.

Deep dive

Use this home equity loan calculator to find your maximum available loan amount from your home’s value and your lender’s combined loan-to-value (CLTV) limit, then estimate a fixed monthly payment, total interest cost, and combined LTV after borrowing.

Enter your home value, current mortgage balance, LTV cap, desired loan amount, APR, and term to see how much you might qualify for, how large the payment would be, and how much equity you would have left in your home.

Compare multiple what-if scenarios—such as lower home values, stricter LTV limits, higher rates, or shorter terms—so you can choose a borrowing plan that fits your budget and keeps CLTV within comfortable bounds before you apply.
