The short answer
Home equity is the part of your home you actually own: its current value minus what you still owe. A $450,000 home with a $337,000 mortgage balance has $113,000 in equity, about 25%. It grows three ways: your down payment, the principal in each payment, and rising home values. It can shrink if values fall. For most families, home equity is their largest source of wealth, and crossing certain levels, especially 20%, changes what's possible.
The simplest way to think about it
Picture your home split into two piles. One belongs to the bank. That's your loan balance. The other belongs to you. That's your equity.
The day you buy, your pile is your down payment. Every month after that, two forces move money from the bank's pile into yours: the principal you pay, and any rise in the home's value. The goal of owning a home, financially speaking, is to move the whole thing into your pile.
We go through the calculation step by step in what is home equity and how is it calculated.
The three things that build it
Your down payment. It's your starting equity. Put 10% down on a $400,000 home and you start with $40,000.
Principal payments. Every payment includes some principal. Early on, it's not much. On a $360,000 loan at 6.5%, you build about $4,024 of equity from payments in the first year. By year ten, that rises to about $7,211 a year. That's the 85% problem at work: early payments go mostly to interest. See why early payments go to interest.
Appreciation. When your home's value rises, your equity rises with it, without you paying a dollar. In many markets, this builds more equity in the early years than your payments do. See how home appreciation builds equity.
A real example over 10 years
Take a $400,000 home bought with 10% down and a $360,000 loan at 6.5%. Here's the equity picture at three different rates of home price growth:
| Home value change per year | Value after 10 years | Equity after 10 years | Share of value you own |
|---|---|---|---|
| Falls 2% | $326,829 | $21,635 | 7% |
| Flat | $400,000 | $94,806 | 24% |
| Rises 3% | $537,567 | $232,372 | 43% |
| Rises 5% | $651,558 | $346,364 | 53% |
Same mortgage, same payments, very different outcomes. You can't control the market. You can control how fast you pay down the balance. Want to see where your own equity stands? A free payoff projection shows it.
What shrinks equity
Falling home values. In the first row above, a 2% yearly decline wipes out most of the equity that the down payment and ten years of payments created.
More debt on the home. Anything you owe that's secured by the house subtracts from your equity.
Selling costs. Equity on paper isn't the same as cash in hand. Agent commissions and closing costs when you sell often take several percent of the price.
The milestones that matter
Not all equity is equal. Certain levels change your options.
| Equity | Loan-to-value | What it typically means |
|---|---|---|
| Under 20% | Above 80% | PMI on most conventional loans, less cushion if you sell |
| 20% | 80% | You can usually request PMI removal and refinance without mortgage insurance |
| 22% | 78% | PMI ends automatically on schedule |
| 50% | 50% | You own more of the home than the bank does |
| 100% | 0% | The home is paid off |
Loan-to-value, or LTV, is just the flip side of equity. See loan-to-value ratio explained.
On our example loan, with no change in value, regular payments take about 7 years and 11 months to reach 20% equity and about 20 years to reach 50%. See how long it takes to reach 20% equity for timelines at other down payments and rates, and the 20% equity milestone for everything it opens up.
How to build it faster
You can't make the market rise, but you can speed up the part you control.
Extra principal payments. On our example, an extra $200 a month raises your equity after 10 years from $94,806 to $128,487, with no appreciation at all.
A shorter loan. A 15-year loan builds equity far faster, at the cost of a higher payment.
Smart improvements. Some projects add more value than they cost. Many don't.
More on each in how to build home equity faster.
Protect what you've built
Equity is wealth, and wealth deserves protection. If your family depends on your income to keep making the payment, mortgage protection is designed to keep the house in the family if something happens to you.
The fastest equity of all
The fastest way to own 100% of your home is to pay it off. Ridgewell's Mortgage Accelerator Program is designed to change how your mortgage is structured, so the income you already have does more of the work. For qualifying households, it is designed to pay off a home in as little as 5 to 7 years.
Payoff timelines are illustrations for qualifying households and are not guaranteed.
Where to start
Calculate your equity today. Find your current balance on your mortgage statement, estimate your home's value from recent sales of similar homes nearby, and subtract. Then divide your equity by the value to get your percentage.
