How This Calculator Works
Max HELOC = (Home value × 80-85%) - Mortgage balance. Draw period: interest-only payments = balance × monthly rate. Repayment: standard amortization on remaining balance over 20 years.
Frequently Asked Questions
Most lenders allow up to 80-85% combined LTV. Formula: (Home Value × 0.85) - Mortgage Balance = Max HELOC. On $500K home with $300K mortgage: up to $125K.
The draw period (usually 10 years) is when you can borrow funds and make interest-only payments. After draw period, you repay principal + interest for 10-20 years.
HELOC: flexible draw, variable rate, interest-only during draw. Home equity loan: fixed amount, fixed rate, immediate repayment. HELOC suits ongoing projects; loans suit one-time needs.
680+ for most lenders. 720+ for best rates. Also need 15-20% equity in your home and DTI below 43%. Lower rates with higher credit scores.
Technically yes, but best for home improvements (interest may be tax-deductible). Risky to use for non-home spending since your home is collateral.
