HELOC rates are often variable; this estimate prices a fixed-rate home equity loan on the drawn amount.
How This Is Calculated
Total equity is home value minus all loans. Tappable equity is (value × LTV cap) − total loans, floored at zero. Primary LTV drives PMI eligibility at 80%. Borrowing cost uses M = P · r(1+r)ⁿ / ((1+r)ⁿ − 1) on the amount borrowed.

Home Equity Loan Calculator: How Much Can I Borrow?
The home equity loan calculator answers the borrowing question with the cap math lenders apply: maximum total debt of 80 to 90% of home value, minus what you already owe.
| Home Value | Mortgage Balance | Tappable at 80% | Tappable at 90% |
|---|---|---|---|
| $350,000 | $220,000 | $60,000 | $95,000 |
| $450,000 | $280,000 | $80,000 | $125,000 |
| $600,000 | $350,000 | $130,000 | $190,000 |
Enter a rate and term on any amount and the calculator shows the monthly payment and total interest, so borrowing power always appears next to its price.
Home Equity Calculator: How Much Equity Do I Have?
This home equity calculator shows the three numbers homeowners conflate: total equity (home value minus everything owed), your loan-to-value ratio, and tappable equity, the portion a lender would actually let you borrow against. Enter your home value and mortgage balance, and the home equity calculator displays all three instantly, with borrowing power shown at the 80%, 85%, and 90% LTV caps lenders actually use.
Example: A $450,000 home with a $280,000 mortgage balance holds $170,000 in total equity, of which $80,000 is tappable at a standard 80% LTV cap.
How to Calculate Home Equity
To calculate home equity, subtract every loan secured by the home, primary mortgage, second mortgage, and any HELOC balance, from the current market value. The percentage version, equity divided by value, is your ownership stake, and its mirror image is the LTV lenders underwrite against. The calculator runs both from two inputs, and the value sensitivity row shows the swing if an appraisal lands 5% off your estimate.
HELOC Calculator: Equity as a Credit Line
A HELOC calculator uses the same tappable equity math with a different product shape: a credit line drawn as needed at a variable rate, rather than a lump sum at a fixed one. The combined LTV handling matters most here, since an existing HELOC balance already counts against the cap on any new borrowing. The payment estimate prices the drawn amount at your quoted rate, and the variable-rate caveat is stated plainly rather than footnoted.
Loan-to-Value Calculator: The Number Lenders Check First
The loan-to-value calculator inside this tool divides total home debt by home value, and that single ratio drives most equity decisions: LTV at or below 80% typically qualifies for PMI removal on the primary mortgage, and every equity product prices better as LTV falls. The calculator flags PMI eligibility automatically and shows exactly how much appreciation or paydown crosses the 80% line when you're close.
Home Equity Calculator With a Second Mortgage
A home equity calculator that ignores existing second loans overstates borrowing power for exactly the people most likely to borrow again. This one folds second mortgages and HELOC balances into combined LTV, the figure lenders actually underwrite, so the tappable number reflects what a bank would really extend rather than what a clean first-mortgage-only formula suggests.
