Home Equity Loan Calculator
Estimate how much you can borrow against your home and what your monthly payment could look like.
What this loan home equity calculator helps you do
A home equity loan lets you borrow against the value you own in your property. This calculator gives you a quick estimate of:
- How much equity you currently have
- Your likely maximum borrowable amount based on lender CLTV limits
- Estimated monthly payment for a fixed-rate home equity loan
- Total interest paid over the full term
It is a planning tool, not a lending commitment. Final approval depends on credit score, debt-to-income ratio, income stability, and lender policy.
How the calculation works
1) Calculate your current equity
Current equity = Home value − Mortgage balance. If your home is worth $450,000 and your balance is $275,000, your raw equity is $175,000.
2) Apply a CLTV cap
Lenders usually use a combined loan-to-value limit (CLTV), such as 80%.
Maximum total debt allowed = Home value × CLTV
Maximum new loan = Maximum total debt − Current mortgage balance
This often means you cannot borrow your full raw equity because the lender keeps a buffer.
3) Estimate payment for your chosen term and rate
For a fixed-rate home equity loan, monthly payment is based on loan amount, APR, and term (in months). The calculator uses the standard amortization formula.
Example use case
Suppose your home is worth $500,000, mortgage balance is $300,000, and lender CLTV cap is 80%:
- Max total debt: $500,000 × 0.80 = $400,000
- Max possible new loan: $400,000 − $300,000 = $100,000
If you request $75,000 at 8.00% for 15 years, your monthly payment is estimated using that requested amount. If you request $125,000, the calculator will show that your request exceeds the estimated limit and cap it to the maximum available amount.
Home equity loan vs. HELOC
Home equity loan
- Lump-sum disbursement
- Usually fixed interest rate
- Predictable monthly payment
HELOC
- Revolving credit line
- Often variable rate
- Payment can change over time
If you prefer stable payments and a clear payoff schedule, a fixed home equity loan is often easier to budget.
Before borrowing: practical checklist
- Compare at least 3 lenders for APR, fees, and closing costs
- Check whether there are prepayment penalties
- Keep emergency savings even after drawing equity
- Borrow for value-building goals when possible (debt consolidation, renovation, major repairs)
- Avoid over-borrowing for short-term discretionary spending
Common mistakes to avoid
- Using an unrealistic home value estimate
- Ignoring appraisal, origination, and title fees
- Forgetting taxes and insurance in your total housing budget
- Stretching repayment term too long and paying far more interest
FAQ
Can I borrow 100% of my equity?
Usually no. Most lenders impose CLTV limits below 100%, commonly 80% to 90%.
Does a better credit score increase my borrowing amount?
It can. Strong credit may improve rate options and approval odds, but property value and CLTV still matter.
Is this estimate guaranteed?
No. This is an educational estimate. Lender underwriting and appraisal determine final terms and loan amount.
