Home Equity Calculator

Q: How do I calculate my home equity?

The formula is simple: Home Equity = Home Value − All Outstanding Loans. All outstanding loans includes your first mortgage, any second mortgage, and any existing HELOC balance. To find your equity percentage, divide equity by home value and multiply by 100. For example: $180,000 ÷ $450,000 × 100 = 40% equity. Use the calculator above to get your exact figures instantly.

Q: How much equity do I need for a HELOC?

Most HELOC lenders require you to retain at least 15% equity after the HELOC — meaning the combined loan-to-value (CLTV) of your mortgage plus HELOC cannot exceed 85% of your home’s value. Some lenders go up to 90% CLTV. As a practical rule: you need at least 20% equity to qualify for most HELOCs, and at least 30% equity to get competitive rates and terms.

Q: Is home equity taxable when I sell my home?

Generally, no — up to a significant exclusion amount. The IRS allows homeowners to exclude up to $250,000 in capital gains from the sale of a primary residence (or $500,000 for married couples filing jointly), provided you have lived in the home for at least 2 of the last 5 years. Gains above those thresholds are taxed as capital gains. Always consult a tax advisor for your specific situation, as rules and exceptions apply.

Find out exactly how much equity you’ve built in your home — and how much of it you can actually access through a HELOC, home equity loan, or cash-out refinance. See your equity amount, percentage, and borrowing power instantly.

How this is calculated: Home value grows at the selected annual appreciation rate. Mortgage balance decreases based on your rate and remaining term. Equity = home value − remaining mortgage balance. Max HELOC = home value × 85% − mortgage balance.

At 80% CLTV — conservative $90,000

Available

Most banks and credit unions offer HELOCs up to 80% CLTV. At this tier you qualify with the widest lender selection and the best available rates. Ideal for borrowers who prioritize rate and flexibility.

At 85% CLTV — most lenders $112,500

Available

The standard HELOC limit at most major lenders. Accessing up to 85% CLTV requires a credit score of 680+ and a debt-to-income ratio under 43%. Rates are slightly higher than at 80%.

At 90% CLTV — select lenders $135,000

Available

Only select credit unions and online lenders offer 90% CLTV HELOCs. Typically requires 720+ credit score, low DTI, and strong income history. Rates are noticeably higher.

Your equity position is strong. At 60% CLTV you qualify for all three tiers. The best strategy is to apply at 85% and use the full credit line capacity — your rate will still be in the competitive tier.

The foundation of home wealth

What is home equity?

Home equity is the portion of your home you actually own — your home’s value minus everything you still owe on it. It’s one of the most powerful forms of wealth most families build, and it grows two ways simultaneously.

The simple definition

Home equity = home value minus all outstanding loans. If your home is worth $450,000 and you owe $270,000, your equity is $180,000. As your loan balance falls and your home value rises, equity increases from both directions at once.

How equity builds over time

Equity grows from two independent sources: mortgage paydown (every payment reduces your loan balance) and home appreciation (rising property values increase what your home is worth). Both work simultaneously — compounding your equity growth year after year.

Why equity is powerful

Home equity is tax-advantaged wealth — capital gains on a primary residence are excluded from taxes up to $250,000 (single) or $500,000 (married). It can also be accessed through a HELOC or home equity loan when you need liquidity, without selling the home.

The trapped equity problem

Most of your equity is inaccessible without borrowing or selling. Lenders typically only allow you to access up to 85% of your home's value through a HELOC or loan. The remaining equity is "trapped" until you sell — which is why accessing it through the right product matters.

Mortgage paydown

Every monthly payment reduces your loan balance. On a $270K mortgage at 6.5%, you pay down approximately $6,800 in principal in year 1 — rising each year as the loan amortizes.

Home appreciation

At 3% annual appreciation, a $450K home gains $13,500 in value in year 1. This directly adds to your equity with no action required on your part.

The compounding wealth effect

How equity builds over time

Home equity grows from two forces working simultaneously. Understanding both helps you make smarter decisions about extra payments, renovations, and when to access your equity.

Purchase year

Equity starts slowly — most payment is interest

In the first year of a 30-year mortgage at 6.5%, roughly 84% of each payment is interest — only 16% reduces your balance. On a $270K mortgage, you pay down about $6,800 in year 1 while paying $17,200 in interest.

Source 1 — Mortgage paydown (controlled)

Every mortgage payment reduces your loan balance — but not equally. Early payments are mostly interest; later payments are mostly principal. This is amortization. You control this source: making extra principal payments accelerates equity build significantly. An extra $300/mo on a $270K, 6.5%, 30-year mortgage saves $102,000 in interest and builds equity 6+ years faster.

Source 2 — Home appreciation (market-driven)

Your home's value rises with the local market. At 3% annual appreciation, a $450K home is worth $521K after 5 years and $604K after 10 years. This added value goes entirely to your equity — your mortgage balance doesn't change when the market rises. Appreciation is passive equity growth that requires no effort.

The early-years trap — why payments feel slow

Most homeowners feel they're "not building equity" in the first 5 years. This is normal — amortization front-loads interest, so early payments barely dent the balance. The fix: even $100–$200/mo extra applied to principal dramatically accelerates equity growth in those early high-interest years.

3 ways to unlock your equity

How to access your equity

Your equity is only valuable if you can access it when you need it. Three main products let you tap your home equity — each with different costs, structures, and ideal use cases.

Most flexible

HELOC

Revolving • Variable rate

A revolving credit line secured by your home equity. Draw what you need, when you need it. Pay interest only on the drawn amount. The most flexible way to access equity — ideal for ongoing or phased needs like renovations.

Rate typeVariable (prime + margin)

Max CLTVUp to 85% (some 90%)

PaymentInterest-only in draw period

Closing costs$0 – $1,500 typical

Best forPhased / ongoing needs

Most predictable

Home equity loan

Lump sum • Fixed rate

Receive a lump sum at closing with a fixed interest rate and equal monthly payments. No variable rate risk. Ideal for a known, fixed-cost project like a full renovation or debt consolidation where you need a defined payoff date.

Rate typeFixed for full term

Max CLTVUp to 85–90%

PaymentFixed P+I from day one

Closing costs1–3% of loan amount

Best forFixed-cost, one-time expense

Largest access

Cash-out refinance

Replaces mortgage • Fixed or ARM

Replace your existing mortgage with a larger one and pocket the difference in cash. Gives access to the largest equity amounts, but replaces your current rate — only smart if today’s rates are at or below your existing mortgage rate.

Rate typeFixed or ARM — new mortgage

Max CLTVUp to 80% (most lenders)

PaymentNew mortgage replaces old

Closing costs2–5% of new loan amount

Best forLarge equity access + rate reset

Which is right for you? If your existing mortgage rate is below current market rates (locked in before 2022), a cash-out refinance will significantly increase your total borrowing cost. In that case, a HELOC or home equity loan is almost always better — it lets you access equity without disturbing your favorable first mortgage. Use the calculator above to see exactly how much equity you can access at each tier.

Home equity FAQ

Common questions about home equity, how it builds, and how to access it — answered clearly.

Home equity is the portion of your home that you own outright — calculated as home value minus all outstanding loan balances. If your home is worth $450,000 and you owe $270,000 on your mortgage, your equity is $180,000. Equity grows two ways: as your loan balance decreases through monthly payments, and as your home’s market value increases over time.

The formula is simple: Home Equity = Home Value − All Outstanding Loans. All outstanding loans includes your first mortgage, any second mortgage, and any existing HELOC balance. To find your equity percentage, divide equity by home value and multiply by 100. For example: $180,000 ÷ $450,000 × 100 = 40% equity. Use the calculator above to get your exact figures instantly.

Most HELOC lenders require you to retain at least 15% equity after the HELOC — meaning the combined loan-to-value (CLTV) of your mortgage plus HELOC cannot exceed 85% of your home’s value. Some lenders go up to 90% CLTV. As a practical rule: you need at least 20% equity to qualify for most HELOCs, and at least 30% equity to get competitive rates and terms.

Yes — significantly. Every extra dollar applied to your mortgage principal reduces your loan balance immediately, which directly increases your equity by the same amount. Extra payments are especially powerful early in the mortgage when most of each payment is interest. An extra $300/month on a $270,000, 6.5%, 30-year mortgage can build equity 6+ years faster and save over $100,000 in total interest.

Generally, no — up to a significant exclusion amount. The IRS allows homeowners to exclude up to $250,000 in capital gains from the sale of a primary residence (or $500,000 for married couples filing jointly), provided you have lived in the home for at least 2 of the last 5 years. Gains above those thresholds are taxed as capital gains. Always consult a tax advisor for your specific situation, as rules and exceptions apply.

It depends on your down payment and market conditions. If you put 20% down at purchase, you start with 20% equity immediately. With a 10% down payment on a home with 3% annual appreciation, you typically reach 20% equity in 3–5 years through the combination of mortgage paydown and appreciation. With a 5% down payment, it typically takes 5–8 years. Making extra principal payments can cut this timeline significantly — even $100/month extra makes a meaningful difference.
