Home Equity: How It Builds and How to Use It
Equity is the part of your home you actually own. Here is how it accumulates and what it is reasonable to do with it.

Home equity is your home's current value minus everything owed against it. A $460,000 home with a $310,000 mortgage carries $150,000 of equity.
The three ways equity grows
- Principal payments. Every payment retires a little debt. Early in a 30-year loan this is a small share of the payment; by year fifteen it is roughly half.
- Appreciation. Market movement, which you do not control and should not count on over short periods.
- Improvements. Renovations may increase value, though usually by less than they cost.

| 10 | $6,980 | $19,570 | $298,600 |
| 20 | $13,340 | $13,210 | $192,000 |
| 30 | $25,600 | $950 | $0 |
Calculating your loan-to-value
Divide what you owe by the home's value. That figure — LTV — determines whether you can cancel mortgage insurance, whether you can borrow against equity, and on what terms. Below 80 percent unlocks most options.
Ways to access equity
- Home equity loan — fixed lump sum, fixed payment
- HELOC — revolving line, usually variable rate
- Cash-out refinance — replaces the first mortgage with a larger one
- Sale — the only method that converts equity to cash without new debt
- Reverse mortgage — for eligible older homeowners; complex, with significant costs and obligations, and worth independent counseling before pursuing
Reasonable and unreasonable uses
Defensible: improvements that maintain or increase the home's value, consolidating higher-rate debt when the underlying spending is under control, education or medical costs when alternatives are worse. Harder to defend: vehicles, vacations, or investing borrowed money — because the collateral is where you live.
Frequently asked questions
How do I find out how much equity I have?
Subtract your mortgage balance from a realistic current value. Use recent comparable sales or a professional appraisal rather than an online estimate for anything that matters.
How fast does equity build?
Slowly at first. In the first five years of a 30-year loan, principal payments alone typically retire 6 to 8 percent of the original balance.
Can I lose equity?
Yes, if values decline or you borrow against it. Homeowners who owe more than the home is worth are described as underwater.
