How do I calculate my home equity?

Home equity equals your home's current market value minus your remaining mortgage balance. For example, if your home is worth $400,000 and you owe $250,000 on your mortgage, your equity is $150,000. You can estimate current value using recent comparable sales or online home value tools, though an official appraisal provides the most accurate figure.

How much home equity can I borrow against?

Most lenders allow you to borrow up to 80–85% of your home's value through a HELOC or home equity loan, minus your existing mortgage balance. So on a $400,000 home with a $250,000 mortgage, you could potentially borrow up to $70,000–$90,000 (80–85% of $400K = $320K–$340K, minus $250K owed). Lenders also evaluate your credit score and debt-to-income ratio.

About This Analysis

This calculator provides estimates based on the inputs you supply. Home values can decrease — past appreciation does not guarantee future growth. HELOC availability depends on credit score, income, and individual lender requirements. PMI removal timelines are estimates based on scheduled payments and projected appreciation. Results are for informational and educational purposes only and should not be considered financial advice.
