Home Equity Loan Calculator

About the Home Equity Loan Calculator

A home equity loan calculator determines how much you can borrow against your home equity, computes your fixed monthly payment, and shows the total interest cost over the loan term. A home equity loan, sometimes called a second mortgage, lets you borrow a lump sum against the equity you have built in your home, typically up to 80 to 85 percent of the home's appraised value minus your current outstanding mortgage balance. Unlike a HELOC which provides revolving access at a variable interest rate, a home equity loan delivers a fixed lump sum at a fixed interest rate with a fixed monthly payment, making it predictable and suitable for large, well-defined one-time expenses such as home renovations, debt consolidation, funding education, or significant personal expenditures. The predictability of a fixed payment is particularly valuable in an uncertain interest rate environment, allowing you to budget with certainty for the full term of the loan. In the United States in 2025, home equity loan rates for well-qualified borrowers typically range from 7.5 to 10 percent, depending on the lender, loan-to-value ratio, credit score, and term length. These rates are meaningfully lower than unsecured personal loan rates, which commonly range from 10 to 20 percent, and dramatically lower than credit card interest rates, which average around 20 to 24 percent in 2025. For a homeowner carrying high-interest credit card debt, consolidating that debt into a home equity loan at a lower fixed rate can produce substantial interest savings over time. However, this strategy converts unsecured debt into debt secured by your home, which fundamentally changes the risk profile: defaulting on a credit card results in collection calls and credit score damage; defaulting on a home equity loan can lead to foreclosure proceedings. The critical distinction must be understood before using home equity to consolidate consumer debt. The home equity loan market is not unique to the United States. In Canada, home equity loans or secured lines of credit at major banks like TD, RBC, BMO, Scotiabank, and CIBC operate on similar combined loan-to-value principles, typically capping total secured debt at 80 percent of the property's appraised value. In the UK, further advances from your existing mortgage lender or second charge mortgages from specialist lenders serve a similar function, with pricing and LTV limits varying by lender. In Australia, the equivalent product is typically a home loan top-up or redraw from an existing mortgage, with most lenders capping total LVR at 80 percent without Lenders Mortgage Insurance. Our calculator models the complete financial picture of a home equity loan: maximum available equity, monthly payment, combined loan-to-value ratio, and total interest cost over the loan term. Understanding all four outputs before approaching a lender helps you borrow the right amount, at terms you can comfortably service, without overextending your equity position. This calculator provides educational estimates only and is not financial advice. All home equity borrowing decisions should be discussed with a qualified mortgage professional who can assess your individual financial situation.

How It Works

The home equity loan calculation proceeds in three steps. Step one determines the maximum available loan amount. Maximum home equity loan equals (Home value times maximum combined LTV) minus existing mortgage balance. Most lenders cap combined LTV at 80 percent, though some lenders will lend to 85 or 90 percent for well-qualified borrowers. Example: $450,000 home, $280,000 existing mortgage, 80 percent maximum CLTV. Maximum loan equals ($450,000 times 0.80) minus $280,000 equals $360,000 minus $280,000 equals $80,000 available. Step two calculates the monthly payment on your chosen loan amount using the standard amortisation formula. Monthly payment equals Loan times [r times (1 plus r) to the power n] divided by [(1 plus r) to the power n minus 1], where r is the monthly interest rate and n is the number of months. If borrowing $50,000 at 8.5 percent for a 10-year (120-month) term: monthly rate r equals 0.085 divided by 12 equals 0.007083. Monthly payment equals $50,000 times [0.007083 times (1.007083) to the power 120] divided by [(1.007083) to the power 120 minus 1] equals approximately $621 per month. Step three calculates total interest cost: total interest equals (monthly payment times number of months) minus loan amount equals ($621 times 120) minus $50,000 equals $74,520 minus $50,000 equals $24,520 in total interest. Combined LTV equals ($280,000 plus $50,000) divided by $450,000 equals $330,000 divided by $450,000 equals 73.3 percent, comfortably within the 80 percent limit.

Tips & Best Practices

• ✓A home equity loan is secured against your home, meaning default can lead to foreclosure. This is the most important distinction from an unsecured personal loan, where default damages your credit but cannot cost you your home. Never borrow more from your home equity than you are confident you can repay reliably even if your income decreases significantly.
• ✓Interest deductibility rules in the US are stricter since 2017. Home equity loan interest is only tax-deductible if the loan proceeds are used to buy, build, or substantially improve the home securing the loan. Using equity loan funds for debt consolidation, vehicle purchases, or personal expenses eliminates the deduction. Always verify the current IRS rules with a tax professional before assuming deductibility.
• ✓The combined loan-to-value ratio matters more than standalone LTV when evaluating home equity lending. A first mortgage at 75 percent LTV combined with a home equity loan of 15 percent creates a combined LTV of 90 percent, above the typical 80 percent limit. The calculator automatically computes your CLTV so you can determine in advance whether your desired loan amount is within standard lender thresholds.
• ✓Shop multiple lenders for home equity loans as rates and fees vary meaningfully. Closing costs on home equity loans typically range from 2 to 5 percent of the loan amount, covering origination fees, appraisal costs, and title work. On a $50,000 loan, closing costs of $1,500 to $2,500 represent 3 to 5 percent of the borrowed amount and should be factored into your effective APR comparison with other borrowing options.
• ✓The fixed rate and fixed payment of a home equity loan provide a meaningful advantage over a HELOC in periods of rising interest rates. Locking in your rate at loan origination protects you from future rate increases for the entire loan term, which is valuable certainty when the interest rate environment is volatile or trending upward.
• ✓Comparing home equity loan terms: a 5-year term minimises total interest but maximises monthly payment. A 15-year term minimises monthly payment but maximises total interest. On $50,000 at 8.5 percent, the 5-year payment is $1,025 per month with $11,500 total interest, while the 15-year payment is $493 per month with $38,700 total interest. Choose the term that balances monthly affordability with minimising total interest cost.
• ✓Credit score significantly affects home equity loan rates. Borrowers with credit scores above 760 typically receive rates near the lower end of the lender's range, while scores between 660 and 720 may add 1.5 to 2 percentage points to the rate. On a $60,000 loan over 10 years, that rate difference costs approximately $7,000 in additional interest. If your credit score is below 720, it may be worth taking 6 to 12 months to improve it before applying.
• ✓If you are considering a home equity loan to fund investments such as shares, managed funds, or additional property, model the after-tax investment return against the after-tax loan cost carefully. Using secured home debt to fund investments that may return less than the interest rate, or that are volatile, creates a serious risk of owing more than your investments are worth at exactly the time property values might also be declining.

Who Uses This Calculator

Homeowners planning major kitchen or bathroom renovations who want the predictability of a fixed monthly payment rather than a variable rate HELOC choose home equity loans for their certainty, particularly for projects with well-defined total costs. A renovation budgeted at $50,000 with a fixed $621 monthly payment over 10 years is easier to budget for than a variable HELOC where the rate, and therefore the payment, can change with every Federal Reserve decision. Borrowers comparing home equity loans against personal loans for large consolidation needs find that the rate differential can be significant: a $40,000 personal loan at 14 percent over 5 years costs approximately $11,000 in interest, while a home equity loan for the same amount at 8.5 percent over 10 years costs approximately $19,600 in total interest. Despite the lower rate, the longer term on the home equity loan means total interest cost can be higher; shorter terms at lower rates generally win. This is an important comparison the calculator helps you model. People evaluating cash-out refinancing versus taking a home equity loan as a second mortgage use the calculator to model total costs. In periods where first mortgage rates are significantly higher than the homeowner's existing rate, a home equity loan preserves the low-rate first mortgage and only borrows the incremental amount needed at the higher second-mortgage rate, potentially saving significant total interest compared to refinancing the entire first mortgage balance. Financial planners helping pre-retirees access home equity to fund retirement income supplements, healthcare costs, or home modifications model the monthly payment against projected retirement income to ensure serviceability without financial stress.
