How it works: Home equity loans allow you to borrow against the equity in your home. Lenders typically limit the combined loan-to-value (CLTV) ratio to 80-90%. This calculator shows your available equity, maximum borrowing capacity, and loan costs. A good credit score and sufficient equity are required for approval. Consider both the monthly payment and total interest costs when deciding.
What Is a Home Equity Loan Calculator?
A home equity loan calculator estimates your monthly payment, total interest, available equity, combined loan-to-value (CLTV) ratio, and maximum borrowing capacity for a second-lien loan. Home equity loans let you borrow against the equity you've built — the difference between your home's current value and what you still owe on your mortgage.
Unlike a HELOC (home equity line of credit), a home equity loan disburses a lump sum at a fixed rate with equal monthly payments over a set term — typically 5–30 years. This makes it predictable and suitable for large one-time expenses: debt consolidation, home renovation, medical bills, or tuition.
The critical constraint is CLTV — combined loan-to-value ratio. Most lenders cap total borrowing (first mortgage + home equity loan) at 80–85% of the home's appraised value. This calculator computes your borrowing ceiling automatically.
How to Use This Home Equity Loan Calculator
- Enter your home's current value (use a recent appraisal or Zillow estimate).
- Enter your remaining mortgage balance.
- Enter the loan amount you want to borrow, interest rate, and term (years).
- The calculator shows: monthly payment, total interest, CLTV ratio, and whether you're within the 80% CLTV limit most lenders require.
- Adjust the loan amount to see how it affects your CLTV and payment.
Worked Example: The Martinez Family's Debt Consolidation
The Martinez family has $45,000 in credit card debt at an average APR of 19% — costing about $712/month in minimum payments. Their home is worth $400,000 with $250,000 remaining on the first mortgage (62.5% LTV). They qualify for a 10-year home equity loan at 8.5%.
| Item | Credit Cards | Home Equity Loan |
|---|---|---|
| Balance | $45,000 | $45,000 |
| Rate | 19% | 8.5% |
| Term | Variable / open | 10 years (fixed) |
| Monthly Payment | ~$712 minimum | ~$558 |
| Total Interest | $50,000+ (if min-only) | ~$21,960 |
| CLTV After | — | 73.8% (within 80% limit) |
The home equity loan saves the Martinezes $154/month and eliminates the credit card debt in exactly 10 years — vs. potentially never, paying minimums at 19%.
Home Equity Rate Comparison Reference
| Debt Type | Typical APR | Monthly on $30k / 5yr | Total 5-Year Cost |
|---|---|---|---|
| Credit Cards | 18–24% | $760–$915 | $45,600–$54,900 |
| Personal Loan | 10–15% | $637–$714 | $38,220–$42,840 |
| Auto Loan | 6–9% | $580–$622 | $34,800–$37,320 |
| Home Equity Loan | 7–10% | $594–$637 | $35,640–$38,220 |
Important: Home equity loans use your home as collateral. Missing payments can result in foreclosure — a risk that credit cards and personal loans do not carry.
Key Concepts: CLTV, Equity, and Home Equity Loan vs. HELOC
CLTV (Combined Loan-to-Value) — (First mortgage balance + home equity loan balance) ÷ home value. Most lenders cap CLTV at 80–85%. On a $400,000 home with a $250,000 first mortgage, the maximum home equity borrowing at 80% CLTV is: ($400,000 × 0.80) − $250,000 = $70,000.
Available equity — Your home's current value minus your first mortgage balance. But lenders won't let you borrow all of it — they require you to retain at least 15–20% equity as a buffer. Calculate accessible equity as: home value × 0.80 − first mortgage balance.
Home equity loan vs. HELOC — A home equity loan is a lump-sum, fixed-rate installment loan. A HELOC is a revolving credit line with a variable rate and a draw period (usually 10 years) followed by a repayment period. Use a home equity loan when you need a specific amount for a one-time project. Use a HELOC when you need ongoing access to funds over time.
Tax deductibility — Interest on home equity loans is tax-deductible if the loan is used to buy, build, or substantially improve the home that secures the loan (IRS Publication 936). Interest used for debt consolidation or personal expenses is generally not deductible after the 2017 Tax Cuts and Jobs Act. Consult a tax professional.
Tips and Common Mistakes
- Borrowing to the CLTV limit — Borrowing up to 80% CLTV leaves zero buffer. If home values drop 10–15%, you'll be underwater on a combined basis. Leave at least 5% margin below the maximum CLTV.
- Using equity for depreciating assets — Taking a home equity loan to fund a vacation, car purchase, or consumer spending converts secured debt into consumption. Your home is on the line for spending that produces no lasting value.
- Forgetting closing costs — Home equity loans typically have 2–5% closing costs ($900–$2,250 on a $45,000 loan), though some lenders offer no-closing-cost options in exchange for a slightly higher rate.
- Ignoring prepayment penalties — Some home equity loans have prepayment penalties if paid off within 3 years. Check the loan terms before signing if there's any chance you'll sell the home or refinance soon.
- Consolidating unsecured debt without changing behavior — Consolidating credit card debt into a home equity loan only helps if you stop using the cards. Many borrowers end up with both the home equity loan and rebuilt credit card balances within 2–3 years.
Frequently Asked Questions
How much can I borrow with a home equity loan?
Most lenders allow borrowing up to 80–85% of your home's value, minus your first mortgage balance. On a $400,000 home with $250,000 owed: ($400,000 × 0.80) − $250,000 = $70,000 maximum.
What is a good interest rate for a home equity loan?
Rates typically range from prime + 0–2%. As of 2024–2025, expect 7.5–10% for borrowers with good credit (700+). Rates are fixed for the life of the loan, unlike HELOCs which are variable.
What credit score do I need for a home equity loan?
Most lenders require 620+ with a minimum of 15–20% equity. For the best rates (7–8%), you'll typically need 700+. Below 620, options are limited and rates are significantly higher.
How long does it take to get a home equity loan?
Typically 2–4 weeks from application to funding. The process includes an appraisal (or automated valuation), title search, underwriting, and closing. Some lenders offer expedited 7–10 day closings.
Is a home equity loan better than a cash-out refinance?
A cash-out refi replaces your first mortgage at a new rate. If your current mortgage rate is lower than today's rates, a home equity loan preserves your first mortgage and borrows separately — usually the better option in a rising-rate environment.
Can I deduct home equity loan interest?
Only if the loan is used to buy, build, or substantially improve the home. Debt consolidation or personal use is generally not deductible under the 2017 Tax Cuts and Jobs Act. Consult a tax advisor for your specific situation.
