This home equity loan calculator estimates the fixed monthly payment on a second mortgage style loan. Enter the loan amount, annual interest rate, and term in months. The result is a standard amortizing payment.
Homeowners use it when planning renovations, consolidating higher rate debt, or estimating cash flow before closing. If you need a revolving line instead of a fixed loan, compare with the HELOC calculator.
How the math works
Payment equals PMT(principal, rate, months). Interest each month is balance times monthly rate. The rest of the payment reduces principal until the term ends.
Worked example
Loan amount $50,000, rate 8 percent, term 180 months (15 years). The estimated payment is about $477.83.
| Input | Value |
|---|---|
| Loan amount | $50,000 |
| Rate | 8% |
| Term | 180 months |
| Monthly payment | ~$477.83 |
How to use the fields
- Principal is the amount you will borrow, not the full home value.
- Rate is the note APR as an annual percent.
- Months is the full amortizing term (for example 120, 180, or 240).
Equity and loan to value
Lenders limit how much you can borrow based on home value and existing mortgage balance. This tool does not check loan to value. Confirm available equity with your lender before treating a payment estimate as an approval.
Fixed loan versus HELOC
A home equity loan usually starts amortizing immediately at a fixed rate. A HELOC may allow draws and interest only periods. Choose the product that matches how you will spend and repay the funds, then size the payment with the matching calculator.
Common mistakes
- Entering home value instead of the loan amount
- Using years in the months field
- Ignoring closing costs that raise the financed balance
- Skipping a first mortgage payment when judging total housing cost
Planning checklist
- List the use of funds and a payoff plan.
- Keep reserves after closing costs.
- Compare a shorter term payment against a longer term payment.
- Recheck debt to income if you will apply for other credit soon.
For a first lien payment estimate, use the mortgage calculator. For payoff timing with extras on an existing loan, see the mortgage payoff calculator.
Cash flow stress test
Add the estimated home equity loan payment to your current first mortgage, taxes, insurance, and other debts. If the combined housing stack leaves little room for repairs or savings, shrink the loan amount or lengthen the term only after you understand the interest cost of that longer schedule.
Run a second scenario with a rate one percentage point higher than the quote you hope for. If that stress payment still fits, you have a safer buffer when markets move between application and lock.
Using proceeds wisely
Home equity loans are often used for durable home improvements that may support value. Using the same funds for short lived consumption can leave the debt outstanding after the purchase is gone. Match the term length to how long the benefit lasts when you can.
If part of the goal is paying off higher rate unsecured debt, confirm the math with a consolidation style payment check and protect against reusing the paid off cards. Equity backed debt still puts the home in the conversation if payments stop.
Closing timeline notes
- Ask whether appraisal, title, and recording fees are due in cash or can be financed.
- Confirm the first payment due date so you do not double stack payments in one month by accident.
- Keep copies of the note, HUD style closing figures, and payment instructions.
- Update your monthly budget the day the loan funds.
A clear payment estimate makes those steps easier because you already know the target cash draw. Refresh the calculator whenever the approved amount or rate changes.
Comparing quotes side by side
Keep a small table of loan amount, rate, months, and estimated payment for each lender. Change only one column at a time when you update the calculator so you know what moved the payment. If two offers share a rate but differ in fees, raise the principal on the fee heavy offer and recompute.
Ask whether the rate is fixed for the full term. A payment that looks fine on a short teaser can jump later. Model the higher later rate if that is part of the product design.
Limitations
Results ignore taxes, insurance, HOA dues, and prepayment rules. Lender quotes may round differently. Treat the figure as a planning estimate until you have a closing disclosure.
