What Builds Your Home Equity?
Home equity grows from two sources working simultaneously: mortgage paydown (each payment reduces your principal balance) and home appreciation (your property's market value increasing over time). In the early years of a mortgage, most of your payment covers interest rather than principal, so appreciation often contributes more to equity growth than your monthly payments do.
Why Equity Matters for a HELOC
Your equity position directly determines how much you can borrow via a HELOC. Most lenders allow you to access up to 80–85% of your home's value, minus what you owe on the mortgage. The higher your equity, the larger the credit line available to you. Use the Borrowing Power Calculator to find your exact maximum based on today's numbers.
This tool projects equity using a consistent appreciation rate. In reality, home values fluctuate and can decline. The long-term US average of 3–4% is a reasonable planning assumption, but your specific market may differ significantly.
