I'm looking to buy a house and need to understand my borrowing power. Is there a good home equity calculator online?

To understand your borrowing power (often called a home affordability or maximum mortgage calculator), you'll want an online tool that looks at your income, monthly debts, and down payment rather than a home equity calculator (which is used for borrowing against a home you already own).

Several great, free online calculators can help you figure out your purchasing power without requiring an account or impacting your credit score:

• NerdWallet Home Affordability Calculator : Excellent for seeing conservative vs. aggressive borrowing limits based on the standard 28/36 debt-to-income rule.
• Zillow Affordability Calculator : Highly intuitive; breaks down your estimated principal, interest, taxes, insurance, and PMI dynamically.
• Bankrate Maximum Mortgage Calculator : Great for crunching your gross income against liabilities to find your absolute maximum monthly payment threshold.
• Fannie Mae Mortgage Affordability Calculator : A clean, official, non-commercial tool to estimate your purchasing limits.

Most of these tools will ask you for your gross annual income, available cash for a down payment , and minimum monthly debt payments (like student loans or car notes) to spit out a realistic price range.

If you'd like an immediate estimate right here, tell me:

• Your gross annual household income (before taxes)
• Your total monthly debt payments (car loans, student loans, minimum credit cards)
• How much you have saved for a down payment

I can calculate a rough estimate of your maximum home price for you.

Yes. One important distinction: if you're buying a house, you probably want a mortgage affordability/borrowing-power calculator rather than a home-equity calculator. Home-equity calculators are mainly for people who already own a home and want to borrow against its value.

Good calculators

• Bankrate Home Equity Calculator — excellent if you already own a home. It estimates how much you could potentially borrow based on home value, mortgage balance, credit score and LTV. Bankrate's example assumes lenders allow borrowing up to roughly 80% of home value, although actual limits vary.
• NerdWallet Home Equity Loan Calculator — useful for estimating both your maximum borrowing amount and monthly payment. It discusses the common 85% combined loan-to-value limit.
• NerdWallet HELOC Calculator — better if you're specifically considering a HELOC.

For figuring out how much house you can buy

I'd instead calculate your mortgage affordability using:

• gross annual income
• monthly debt payments
• down payment
• credit score
• expected interest rate
• property taxes
• homeowners insurance
• HOA dues, if applicable

If you give me your annual income, monthly debt payments, approximate down payment, credit-score range, and the country/state where you're buying, I can estimate a sensible maximum home price and monthly payment, and explain what lenders are likely to consider.

To understand your borrowing power or how much house you can afford, you will want to use a Home Affordability Calculator rather than a home equity calculator (home equity is for people who already own a home and want to borrow against its value).

Several reliable, free online calculators let you plug in your income, monthly debts, and savings to estimate your purchasing power:

• NerdWallet Home Affordability Calculator : Great for getting a realistic snapshot based on standard debt-to-income (DTI) ratios, factoring in current average mortgage rates.
• Bankrate Home Affordability Calculator : Allows you to input location-specific property taxes, insurance, and HOA dues alongside your income and debts.
• Calculator.net House Affordability Calculator : Highly customizable, letting you tweak your DTI thresholds manually from 10% to 50% to see conservative vs. aggressive budgets.
• Realtor.com Affordability Calculator : Links your estimated buying power directly with geographic locations and real-time housing costs.

If you'd like an initial ballpark right here, tell me:

• Your gross annual household income (before taxes)
• Your total monthly debt payments (car loans, student loans, minimum credit card payments)
• The amount you have saved for a down payment

I can run a quick estimate for your potential budget!

Yes—but since you’re buying a house, you probably want a mortgage affordability calculator, not a home-equity calculator. Home equity calculators are mainly for people who already own a home and want to borrow against its equity.

A couple of good options:

• Bankrate Home Affordability Calculator — useful for estimating the home price you can afford based on income, debts, down payment, and mortgage assumptions. Bankrate also has a separate home-equity calculator.
• Chase Home Affordability Calculator — lets you enter income/expenses and adjust the interest rate and loan term to see estimated home price, loan amount, down payment, and payment.
• NerdWallet Home Equity Loan Calculator — good if you actually meant borrowing against a home you already own. It estimates maximum borrowing and payments.

For figuring out your borrowing power, I’d start with the affordability calculator. The important inputs are your gross annual income, monthly debt payments, down payment, credit-score range, and estimated interest rate. The lender will ultimately look at your debt-to-income ratio and full financial profile, so a calculator is an estimate rather than a preapproval.

If you give me those numbers, I can also estimate your likely maximum home price, loan amount, and monthly payment and show you a conservative vs. maximum-budget scenario.

Yes — but since you’re buying a house, you probably want a home affordability / mortgage borrowing-power calculator, rather than a “home equity” calculator. Home equity calculators are mainly for people who already own a home and want to estimate how much they can borrow against it.

Good options

• CFPB home-buying affordability guidance — My first choice for a neutral starting point. The Consumer Financial Protection Bureau explains how to work backward from a comfortable monthly payment to an affordable loan and home price.
• Bankrate mortgage calculator — Useful for testing different home prices, down payments, rates, terms, and credit-score assumptions.
• Bankrate home equity calculator — Use this instead if you already own a home and are asking how much equity you could borrow against.

One important distinction: “How much will a lender approve me for?” isn't necessarily the same as “How much house can I comfortably afford?” The CFPB specifically recommends considering taxes, insurance, mortgage insurance, HOA costs, other debts, and your broader budget—not just the lender's maximum.

If you give me your annual household income, monthly debt payments, down payment, approximate credit score, and state, I can also estimate your rough borrowing power and target home-price range and explain the assumptions.

To understand your borrowing power when buying a house, you will want to look for a home affordability calculator (as "home equity calculators" are typically used for borrowing against a home you already own).

Several free, user-friendly online tools provide accurate estimates based on your income, debts, and down payment:

• NerdWallet How Much House Can I Afford Calculator : Excellent for visualizing the standard 28/36% debt-to-income rules of thumb and breaking down monthly costs.
• Bankrate Home Affordability Calculator : Highly customizable, letting you tweak location-based taxes, insurance, and current interest rates.
• Fannie Mae Mortgage Affordability Calculator : A clean, straightforward tool backed by one of the largest government-sponsored mortgage enterprises, requiring no registration.
• Zillow House Affordability Calculator : Great for quickly seeing a ballpark purchase price alongside estimated principal, interest, taxes, and insurance (PITI).

Key Inputs You Will Need

To get an accurate result from any of these tools, have these numbers ready:

1. Gross annual income : Your total household income before taxes.
2. Monthly debts : Minimum payments on credit cards, auto loans, student loans, etc.
3. Cash saved : The amount you have for your down payment and closing costs.
4. Location/Zip Code : Property taxes and insurance rates vary drastically by region.

If you'd like, share:

• Your approximate gross annual income
• Your total monthly debt payments
• How much you have saved for a down payment

I can give you a quick, preliminary estimate of your price range.

To understand your total borrowing power when buying a new house , you actually want a Home Affordability Calculator rather than a home equity calculator.

• A Home Equity Calculator tells you how much money you can borrow against a home you already own by tapping into your current property value minus what you currently owe.
• A Home Affordability/Borrowing Power Calculator looks at your income, existing monthly debts, down payment savings, and estimated local property taxes to tell you the maximum purchase price you qualify for.

Top online tools to check your home-buying borrowing power include:

• NerdWallet Home Affordability Calculator : Excellent for running quick scenarios based on your income, debt-to-income ratio, and current interest rates.
• Zillow Home Affordability Calculator : Great for estimating comfortable monthly payments relative to your gross monthly income.
• Bankrate Home Affordability Calculator : Helpful for factoring in regional variables like local property taxes, homeowners insurance, and various loan terms.
• Rocket Mortgage Affordability Calculator : A straightforward tool that also accounts for your available cash reserves for down payments and closing costs.

If you'd like an immediate ballpark estimate right here, tell me:

• Your gross annual household income (before taxes)
• Your total minimum monthly debt payments (car loans, student loans, credit cards)
• How much you have saved for a down payment

I can run the baseline numbers to give you an estimated price range before you use the online tools.

Yes. Since you’re trying to understand how much house you can afford, you’ll probably want a mortgage borrowing-power calculator rather than only a home equity calculator (home equity calculators are mainly for people who already own a home and want to borrow against it).

A few good options:

• Wells Fargo mortgage calculators — includes a mortgage qualification calculator that estimates how much you may be able to borrow.
• Bankrate home equity calculator — useful if you already own a home and want to estimate available equity.
• Citi home equity calculator — another simple equity-based calculator using home value and remaining mortgage balance.

For a first estimate of your buying power, plug in:

• annual income (and co-borrower income, if applicable)
• monthly debts (car loans, credit cards, student loans, etc.)
• down payment/savings
• estimated interest rate
• desired loan term
• credit score range

Keep in mind online calculators are estimates; lenders also look at debt-to-income ratio, credit history, employment, and their own underwriting rules.

If you tell me your annual income, monthly debts, down payment amount, and state, I can help you estimate a realistic home price range.

Yes. There are several reliable online calculators, and the best one depends on what you're trying to estimate.

If your goal is borrowing power based on your home's equity, these are good options:

• urlFreddie Mac Home Equity Calculatorturn0search2 – A straightforward calculator that estimates how much equity you've built in your home.
• urlBankrate Home Equity Loan Calculatorturn0search3 – Estimates how much you may be able to borrow based on your home's value and current mortgage balance, and explains how lenders calculate available equity.
• urlBank of America HELOC Payment Calculatorturn0search1 – Helpful if you're considering a home equity line of credit (HELOC) and want to estimate monthly payments.
• urlNerdWallet Home Equity Loan Calculatorturn0search5 – Estimates your potential borrowing limit and monthly payments.

A quick rule of thumb is:

• Home equity = Current home value − Remaining mortgage balance
• Many lenders allow a combined loan-to-value (CLTV) of about 80%–85%, though the exact limit depends on the lender, your credit profile, income, and other factors.

If, instead, you're asking about how much mortgage you can qualify for when buying a house, that's a mortgage borrowing power (or affordability) calculator, which is different from a home equity calculator.

If you tell me:

• your country,
• your annual household income,
• your monthly debts,
• your down payment, and
• whether you already own a home,

I can help estimate your borrowing power or point you to the most appropriate calculator.

Since you are looking to buy a house rather than borrow against a property you already own, you will want a home affordability calculator (which calculates your purchasing power and borrowing capacity) rather than a home equity calculator (which is used by current homeowners to borrow against their existing property).
