How It Works

Knowing where you stand on home equity, your Loan-to-Value (LTV) ratio, and how much a Home Equity Line of Credit (HELOC) might open up is a practical starting point for tapping the value built into your property. That picture changes as you pay down the loan and as prices move, so it is worth revisiting as part of any financial plan.

Equity is simply your current home value minus the outstanding mortgage balance. LTV comes from dividing that mortgage balance by the home value and multiplying by 100. Lenders set their own combined loan-to-value limits, so the borrowing-power table shows two versions: 80% of your home value minus what you still owe, and the same at 90%. The equity breakdown estimates where your equity came from by assuming you bought with a loan of 80% of the price: the implied purchase price is your original loan ÷ 0.80, the down payment is that price minus the original loan, principal paid down is the original loan minus today's balance, and appreciation is today's value minus the implied price, also shown as an annual rate over the years you have owned the home.

Get the home value right by leaning on recent comparable sales rather than a hopeful guess, because misjudging your market value is one of the easiest ways to throw off every number that follows. Bear in mind too that equity alone won't secure approval; lenders also weigh your credit score and income. Borrow with a repayment plan you can live with, and resist stretching the leverage to its limit.

Example: Unlocking Equity for a Renovation

  1. 1 Input: Current Home Value = $450,000, Original Loan Amount = $280,000, Current Loan Balance = $200,000, Years Owned = 8.
  2. 2 Equity and LTV: $450,000 − $200,000 = $250,000 of equity, 55.6% of the value; LTV = $200,000 ÷ $450,000 = 44.4%.
  3. 3 Where the equity came from: at the assumed 80% purchase LTV, the implied price was $280,000 ÷ 0.80 = $350,000, so the down payment was $70,000; principal paid down is $280,000 − $200,000 = $80,000; appreciation is $450,000 − $350,000 = $100,000, about 3.2% a year over 8 years. $70,000 + $80,000 + $100,000 = $250,000.
  4. 4 HELOC borrowing power: $450,000 × 0.80 − $200,000 = $160,000 at an 80% limit, or $450,000 × 0.90 − $200,000 = $205,000 at 90%. With an LTV of 44.4% you have room under either limit, but approval also depends on your credit and income, so check the actual terms with a lender.

Frequently Asked Questions

How do I calculate my home equity?
Home equity equals your home current market value minus your remaining mortgage balance. For example, a home worth $400,000 with a $250,000 mortgage has $150,000 in equity.
How much home equity can I borrow against?
Each lender sets its own limit. Many take a percentage of the appraised value and subtract what you owe on the mortgage; the CFPB's example uses 75%. This calculator shows the result at 80% and at 90% combined loan-to-value (CLTV), and approval also depends on your credit score and income.
Does home equity count as taxable income?
No, home equity itself is not income. However, if you sell your home for a profit exceeding $250,000 (single) or $500,000 (married filing jointly), the excess gain is subject to capital gains tax.
