This Home Equity Loan Calculator uses industry-standard loan amortization formulas and loan-to-value (LTV) calculations commonly used by mortgage lenders. Results are intended for educational planning purposes only and should not be considered a loan offer, lending decision, or financial advice.
Home Equity Loan Calculator
A home equity loan calculator estimates your available borrowing power, monthly payment, total interest cost, and repayment timeline using your home value, mortgage balance, interest rate, and loan term.
Also known as a second mortgage calculator or equity loan calculator, this tool helps homeowners evaluate financing options before applying with a lender.
What Is a Home Equity Loan?
A home equity loan lets you borrow a lump sum of money using the equity in your home as collateral. Lenders sometimes call it a second mortgage because it sits behind your existing mortgage on the same property — which is why you'll often see this exact tool searched for as a "second mortgage calculator" or "2nd mortgage calculator."
Home equity is the gap between what your home is worth today and what you still owe on it. The more you have paid down, or the more your home's value has grown, the larger that gap — and the more you can typically borrow.
Most home equity loans pay out as one upfront amount with a fixed interest rate, a fixed monthly payment, and a set repayment term — usually 5 to 30 years. That fixed structure is what separates it from a credit card or a HELOC, and it's why budgeting around it is easier for most U.S. homeowners.
What People Use a Home Equity Loan For
Home improvements and renovations
Consolidating higher-interest debt, like credit cards
Education, medical bills, or other large one-time expenses
Big planned purchases or long-term financial goals
Because your home backs the loan, borrow only what you can comfortably repay. Use the calculator above to see your estimated payment before you talk to a lender.
How Does a Home Equity Loan Calculator Work?
Our home equity loan calculator turns five inputs into a complete borrowing picture instantly: home value, outstanding mortgage, loan-to-value (LTV), interest rate, and loan term.
Change any field above and every result updates in real time — no submit button needed. People searching for a "home equity loan rates calculator" or a "loan calculator home equity" tool are usually looking for exactly this.
It gives you a simple way to compare different borrowing scenarios, interest rates, and repayment terms before applying with a lender.
What the Calculator Uses
Behind the scenes, it runs the same math a loan officer would use, then builds a full year-by-year amortization schedule so you can see exactly how your balance shrinks over time.
The output also includes a detailed chart and downloadable year-by-year repayment schedule for deeper financial planning.
How Much Home Equity Can I Borrow?
Most lenders cap your combined loan-to-value (CLTV) — your existing mortgage plus the new home equity loan — between 80% and 90% of your home's value. The exact cap depends on the lender, your credit score, and your income.
The Borrowing Power Formula
Max Borrowable = (Home Value × LTV%) − Outstanding Mortgage
Worked Example
Expert Tip
Click "Set Max" next to the Requested Loan Amount field above to auto-fill the highest amount your LTV setting allows — then dial it back if you only need part of it.
Home Equity Loan Requirements
Before a lender approves a home equity loan, they check that you actually have equity to borrow against and that you can afford the new payment on top of your existing mortgage.
Here's what most lenders look at when deciding who qualifies for a home equity loan.
| Requirement | Typical Minimum |
|---|---|
| Home equity | At least 15–20% of your home's value |
| Credit score | Around 620 or higher |
| Debt-to-income (DTI) ratio | Generally 43% or below |
| Proof of income | Pay stubs, W-2s, or tax returns |
| Home appraisal | Confirms current market value |
Who Qualifies for a Home Equity Loan
In general, you're a good candidate for home equity loan eligibility if you've built up meaningful equity (either through paying down your mortgage or rising home values) and have a stable, documented income.
Your total monthly debts — including the new loan — should also stay within a lender's DTI limit.
Documentation timelines and exact thresholds vary by lender, so treat the figures above as a general benchmark. Once you have a rough idea of your numbers, run them through the calculator above to see what loan amount and payment they might support.
Home Equity Loan Calculator Formula
Your monthly payment is calculated with the same fixed-rate amortization formula lenders use for mortgages and EMIs:
M = P × r × (1 + r)n ÷ [(1 + r)n − 1]
What Each Variable Means
| Symbol | Meaning |
|---|---|
| M | Monthly payment |
| P | Loan principal (amount borrowed) |
| r | Monthly interest rate (annual rate ÷ 12) |
| n | Total number of monthly payments (years × 12) |
This formula gives a fixed payment for the full term. Each month, more of it goes toward principal and less toward interest — that's what an amortization schedule tracks, and it's exactly what the table further down this page shows for your numbers.
How to Calculate a Home Equity Loan Payment
If you're wondering how to calculate a home equity loan payment by hand, you'd plug your loan amount, monthly rate, and number of payments into the amortization formula above — but it's tedious and easy to get wrong.
Our calculator does the same math instantly and supports 16 currencies, including USD, INR, EUR, GBP, CNY, AUD, CAD, and more.
Follow these steps to calculate home equity loan payments:
- Select your currency.
- Enter your Home Value and Outstanding Mortgage.
- Drag the LTV slider to set how much equity you want to unlock.
- Type a Requested Loan Amount, or leave it blank to auto-use the maximum.
- Enter your Annual Interest Rate and Loan Term.
- Pick a Start Month and Start Year.
- Optionally add an Extra Monthly Payment to see faster payoff and interest savings.
Results, charts, and the amortization table update the instant you change any field — there's nothing to click.
This makes it easy to test "what if" scenarios, like how do you calculate a home equity loan payment differently across a 10-year versus a 20-year term.
Home Equity Loan Payment Examples
Here's what a fixed-rate home equity loan payment calculator shows at three common loan amounts, assuming a 9.5% annual rate over a 10-year term. Use these as a starting reference, then plug in your own rate above for an exact figure.
| Loan Amount | Monthly Payment | Total Interest | Total Cost |
|---|---|---|---|
| $50,000 | $646.99 | $27,638.53 | $77,638.53 |
| $100,000 | $1,293.98 | $55,277.07 | $155,277.07 |
| $200,000 | $2,587.95 | $110,554.14 | $310,554.14 |
Figures rounded to the nearest cent. Calculated using the standard amortizing-loan formula at 9.5% APR over 120 months.
Notice that doubling the loan amount roughly doubles the payment and the interest — the rate and term stay the same, so the cost scales in proportion to what you borrow.
10-Year Home Equity Loan Payments
A 10-year home equity loan repays over 120 fixed monthly installments.
Many homeowners use a 10 year home equity loan payment calculator to see this term specifically, since it's a popular middle ground that helps you become debt-free faster and cut total interest, even though the monthly payment is higher than on a longer loan.
Term Comparison: $100,000 Loan at 9.5%
| Term | Monthly Payment | Total Interest |
|---|---|---|
| 5 years | $2,100.19 | $26,011.17 |
| 10 years | $1,293.98 | $55,277.07 |
| 15 years | $1,044.22 | $87,960.44 |
| 20 years | $932.13 | $123,711.49 |
Going from 10 to 20 years lowers the monthly payment by about $362 — but more than doubles total interest paid. Set Loan Term to 10 in the calculator above and compare it against 15 or 20 instantly.
Home Equity Loan Interest Calculation Explained
On a fixed-rate home equity loan, your monthly payment never changes — but the mix inside it does. Interest is charged only on your remaining balance, so as that balance drops, less of each payment goes to interest and more goes to principal.
Monthly interest formula:
Monthly Interest ≈ Remaining Balance × (Annual Rate ÷ 12)
Early in the loan, your balance is highest, so interest takes the biggest bite. By the final year, almost the entire payment reduces principal. This pattern is called amortization, and it's exactly what the year-by-year table above breaks down for you.
Adding extra payments speeds this up because every extra dollar reduces the balance that future interest is calculated on — which is why the Extra Monthly Payment field above can shrink your total interest noticeably.
Factors That Affect Home Equity Loan Interest Rates
Home equity loan rates vary by lender, even for borrowers who look similar on paper. Knowing what moves the rate helps you understand the quotes you receive and shop more effectively.
- 📊 Credit score — higher scores generally unlock lower rates.
- 🏠 Loan-to-Value (LTV) — borrowing a smaller share of your equity can lower your rate.
- ⏱️ Loan term — shorter terms often carry slightly lower rates and always lower total interest.
- 💵 Loan amount — very small or very large loans can sit in different pricing tiers.
- 📉 Broader market conditions — overall rate trends shift what every lender offers.
How to Compare Offers
1. Collect multiple quotes
Banks, credit unions, and online lenders often price the same borrower differently.
2. Check the APR, not just the rate
APR folds in certain fees, giving a fuller view of true borrowing cost.
3. Weigh rate against term
A lower rate over a much longer term can still cost more in total interest.
4. Run each quote through this calculator
Enter each lender's rate and term above to compare payments side by side.
Also factor in closing costs and any early-payoff penalty before you commit — those can outweigh a slightly lower headline rate.
What Credit Score Do You Need for a Home Equity Loan?
Most lenders set a minimum credit score around 620 for a home equity loan, but where you land in that range strongly shapes the rate you're offered.
| Credit Score Range | Tier | What It Typically Means |
|---|---|---|
| Below 620 | Limited | Many lenders decline; specialty programs may still apply. |
| 620 – 679 | Fair | Approval is possible, usually at a higher rate. |
| 680 – 739 | Good | Competitive rates from most lenders. |
| 740+ | Excellent | Access to the lowest advertised rates. |
Expert Tip
Paying down revolving credit card balances 1–2 months before applying often moves your score into a better tier faster than any other single action.
Lenders also weigh your debt-to-income ratio and income documentation alongside your score, so a strong score alone doesn't guarantee the lowest rate.
How to Pay Off a Home Equity Loan Faster
Every extra dollar you put toward principal stops accruing interest immediately. Even a modest, consistent extra payment can shave years off your loan and save thousands.
Real Example: $200,000 Loan at 9.5% Over 10 Years
| Scenario | Payoff Time | Total Interest |
|---|---|---|
| No extra payment | 10.0 years | $110,554.14 |
| +$200/month extra | 8.9 years | $96,685.94 |
An extra $200/month here saves roughly $13,868 in interest and pays off the loan about 13 months early.
Other Ways to Speed Up Payoff
Make one extra full payment per year, e.g., from a tax refund or bonus.
Split your payment in half and pay every two weeks instead of once a month.
Refinance into a shorter term once rates drop or your equity grows.
Before adding extra payments, confirm your loan doesn't carry a prepayment penalty — most don't, but it's worth a quick check with your lender.
Home Equity Loan vs HELOC
Both let you borrow against your home's value, but they're structured very differently. Here's the side-by-side breakdown.
🏠 Home Equity Loan
- • Lump sum paid upfront
- • Usually a fixed interest rate
- • Same payment every month
- • Best for one-time, known expenses
💳 HELOC
- • A credit line you draw from as needed
- • Usually a variable interest rate
- • Payment fluctuates with balance and rate
- • Best for ongoing or unpredictable costs
Which fits you better?
Choose a Home Equity Loan if:
- • You know the exact amount you need.
- • You want a fixed payment and clear payoff date.
Choose a HELOC if:
- • Your costs are spread out over time.
- • You want flexibility to draw only what you need.
Our calculator is built for fixed-term loans, but you can still model a HELOC by entering the balance you'd draw and a comparable fixed term to estimate what a structured repayment would look like.
Home Equity Loan Calculator vs. Doing the Math Yourself
You can calculate a home equity loan payment with a spreadsheet or by hand using the amortization formula above — but a calculator that's purpose-built for home equity, rather than a generic loan calculator, catches a few things manual math usually misses.
| Task | Manual Math | This Calculator |
|---|---|---|
| Finding your max borrowable amount via LTV | Separate calculation, easy to mis-apply CLTV | Built into the LTV slider automatically |
| Modeling extra payments | Requires rebuilding the schedule month by month | Updates instantly with one field |
| Comparing two loan terms side by side | Two full spreadsheets to maintain | Change one field, compare instantly |
| Seeing the full year-by-year payoff curve | Manual amortization table, prone to rounding drift | Chart and exportable table generated for you |
The underlying formula is identical either way — what the calculator above changes is how fast you can test different LTV limits, rates, terms, and extra payments before you ever sit down with a lender.
How We Calculate Your Results
We believe a calculator should show its work. Here is exactly how this tool turns your inputs into results — no hidden assumptions.
Our Calculation Steps
Available Equity
We subtract your Outstanding Mortgage from your Home Value.
Maximum Borrowable
We multiply Home Value by your chosen LTV%, then subtract the Outstanding Mortgage. Negative results are floored to zero.
Monthly Payment
We apply the standard fixed-rate amortization formula shown earlier on this page to your final loan amount, rate, and term.
Amortization Schedule
We step through every month of the loan, splitting each payment into interest and principal, applying any extra payment directly to principal, and rolling the totals up by year for the table and charts.
This calculator gives an estimate for planning purposes — it is not a loan offer. Your actual rate, fees, and approved amount are set by your lender after reviewing your full application.
