Mortgage Heloc Calculator
A Mortgage HELOC Calculator helps homeowners determine how much credit they can access through a Home Equity Line of Credit (HELOC). It uses your homeโs current value, remaining mortgage balance, and lender limits to calculate your available equity and estimated monthly payments.
A HELOC works like a credit card โ you can borrow, repay, and borrow again, making it a flexible financial tool for home improvement, debt consolidation, or major purchases.
How To Use the Mortgage HELOC Calculator
- Enter your homeโs current market value.
- Input your remaining mortgage balance.
- Enter your interest rate (annual percentage).
- Choose your repayment term (in years).
- Click Calculate to get:
- Your available credit line
- Estimated monthly payments
- Total interest over the term
Formula Used
Available HELOC Amount: Available Credit=(Home Valueร0.85)โMortgage Balance\text{Available Credit} = (\text{Home Value} \times 0.85) – \text{Mortgage Balance}Available Credit=(Home Valueร0.85)โMortgage Balance
(Most lenders allow borrowing up to 85% of your homeโs equity.)
Monthly Payment Formula (for fixed-term repayment): M=Pรrร(1+r)n(1+r)nโ1M = \frac{P \times r \times (1 + r)^n}{(1 + r)^n – 1}M=(1+r)nโ1Pรrร(1+r)nโ
Where:
- M = Monthly payment
- P = Principal (loan amount)
- r = Monthly interest rate (annual รท 12)
- n = Number of months
