The best free mortgage calculator depends on the question you are asking. For "how much house can I afford?", the IncomeChecker.com Mortgage Affordability Calculator ranks first because it solves for the home price from your income and debts using lender ratios. For the most detailed payment breakdown, Calculator.net is the best mortgage calculator we tested. We compared five free tools on inputs, schedules, extra payments, and whether they ask for your contact details.
Want to know the price range before you shop? Try the free mortgage affordability calculator.
Key Takeaways
- Most mortgage calculators answer "what is my payment for this price?" Only an affordability calculator answers the reverse question, "what price fits my income?", which is what you need before you start shopping.
- A realistic payment needs more than principal and interest. Property tax, homeowners insurance, HOA dues, and mortgage insurance can add hundreds of dollars a month, so pick a calculator with those fields.
- Calculator.net is the most detailed free payment calculator, with yearly cost increases, biweekly payments, and up to ten one-time extra payments.
- Bankrate and NerdWallet pair the calculator with live rate offers. That is useful for rate shopping, but expect lender advertising alongside your results.
- Small rate changes matter. On a $250,000, 30-year loan, the payment at 6.5% is $1,580.17, and adding $200 a month pays it off 95 months sooner and saves about $97,618 in interest.

The IncomeChecker.com Mortgage Affordability Calculator applies lender debt-to-income limits to your numbers.
Calculate what you can affordWhat a Mortgage Calculator Actually Is (and What It Is Not)
A mortgage calculator estimates the monthly payment on a home loan. The core formula is the same everywhere: payment = loan × r ÷ (1 − (1 + r)^−n), where r is the monthly interest rate and n is the number of monthly payments. A $250,000 loan at 6.5% for 30 years works out to $1,580.17 a month in principal and interest.
Good calculators go further. They add property tax, homeowners insurance, HOA dues, and private mortgage insurance to show your full monthly housing cost. They produce an amortization schedule that splits each payment into interest and principal, and they let you test extra payments to see how much interest and time you save.
Specialized calculators answer different questions. An affordability calculator works backward from your income and debts to the highest price that fits the 28% and 36% debt-to-income ratios many lenders use. FHA and VA calculators add those programs’ mortgage insurance premium or funding fee. A rent-versus-buy calculator compares the total cost of each over the years you plan to stay.
A mortgage calculator is not a loan offer or a pre-approval. It uses the numbers you type in, and a lender will verify your income, credit, and assets before quoting a real rate. Treat every result as a planning estimate, then confirm it with a Loan Estimate from at least two lenders.
How We Ranked These Free Mortgage Calculators
We tested each calculator in October 2026 and scored it on the same five criteria:
- Inputs covered. Whether it accepts property tax, insurance, HOA, PMI, and loan term, so the result reflects a full monthly housing cost.
- Outputs. Monthly payment breakdown, total interest, payoff date, and a monthly or yearly amortization schedule.
- Extra payments. Whether you can model extra monthly, yearly, or one-time payments and see interest saved.
- Question answered. Payment from price, price from income (affordability), or rate impact from credit score and down payment.
- Friction. Whether you must enter a ZIP code, credit score, or contact details, and how much lender advertising sits beside the results.
The Best Free Mortgage Calculators in 2026
These are the five best free mortgage calculators in 2026. Each one is the best answer to a different question, so use the "best for" label to pick the right one. All five are free to use without creating an account.
1. IncomeChecker.com Mortgage Affordability Calculator, best for finding how much house you can afford
Free, no sign-up
Most mortgage calculators make you guess a home price first. The IncomeChecker.com Mortgage Affordability Calculator works the other way: enter your gross income, monthly debts, down payment, and rate, and it solves for the highest home price that fits the debt-to-income limits lenders use. It applies the 28% housing ratio and the 36% total debt ratio, uses whichever is lower, and shows the full monthly payment including property tax, insurance, and HOA dues.
With $100,000 a year in income, $500 a month in other debts, and $40,000 down at 6.5% for 30 years, the housing limit is $2,333 a month. With 1.1% property tax and $1,800 a year of insurance, that supports about a $336,610 home with a $296,610 loan and a $1,874.77 principal and interest payment.
It sits inside a full set of free calculators. The amortization calculator produces a monthly or yearly schedule with extra payments, the FHA and VA calculators add the upfront and annual mortgage insurance premium or funding fee, and the closing cost and rent-versus-buy calculators cover the rest of the decision. None of them ask for a ZIP code, credit score, or email address.
Key numbers
- Solves for the highest home price from income, debts, down payment, and rate
- Applies the 28% housing and 36% total debt-to-income limits many lenders use
- Includes property tax, homeowners insurance, and HOA dues in the payment
- Example: $100,000 income, $500/month debts, $40,000 down at 6.5% → about $336,610 home
- Companion calculators: amortization with extra payments, FHA, VA, closing costs, and rent vs. buy
- No ZIP code, credit score, or contact details required
Best suited for
First-time buyers setting a budget before they talk to a lender or agent. It is also useful for anyone checking whether a raise, a paid-off car loan, or a bigger down payment changes their price range.
2. Calculator.net Mortgage Calculator, best for the most detailed payment and payoff breakdown
Free
Calculator.net has the most complete free mortgage payment calculator we tested. Beyond price, down payment, term, and rate, you can enter property tax, homeowners insurance, PMI, HOA dues, and other costs as either a percentage or a dollar amount, and set a loan start month and year so the payoff date is real.
Its standout features are for planning ahead. "More options" lets you set yearly increases for taxes, insurance, and HOA dues, which most calculators ignore. You can add extra monthly, yearly, or one-time payments, plus up to ten specific one-time payments in chosen months, and toggle a biweekly comparison.
Results include the monthly principal and interest, total monthly cost, lifetime totals with a pie chart, total interest, the payoff date, and both monthly and yearly amortization schedules. The interface is dense and plain, which is the tradeoff for that much control.
Key numbers
- Inputs: price, down payment, term, rate, start date, property tax, insurance, PMI, HOA, and other costs
- Models yearly increases in property tax, insurance, HOA, and other costs
- Extra payments: monthly, yearly, one-time, plus up to 10 dated one-time payments
- Biweekly payment comparison toggle
- Outputs monthly and yearly amortization schedules with a balance chart
- Part of a site with calculators across finance, health, and math
Best suited for
Owners and buyers who want to model extra payments, biweekly schedules, or rising taxes over the life of the loan. It is less friendly for someone who just wants a quick estimate.
3. Bankrate Mortgage Calculator, best for checking a payment against live rate offers
Free
Bankrate’s calculator is built around rate shopping. Enter the home price, down payment, credit score range, and ZIP code, choose a 10, 15, 20, or 30-year term, and pick a rate: Bankrate’s top offer, the national average, or your own number. Property tax, insurance, and HOA dues are pre-filled with rough estimates you can edit or zero out.
The output includes the monthly payment and an amortization tab with total loan cost, and you can add an extra monthly payment. Bankrate’s guide on the same page notes that private mortgage insurance generally costs 0.46% to 1.50% of the loan each year, which is a useful range when you put down less than 20%.
Because Bankrate is a lender marketplace, results sit beside rate offers and lender advertising. That is helpful when you want to see what a payment looks like at a real current rate, but it adds noise if you only want the math.
Key numbers
- Inputs: home price, down payment ($ or %), credit score range, ZIP code, and loan term (10, 15, 20, or 30 years)
- Interest rate options: Bankrate’s top offer, the national average, or your own rate
- Pre-filled, editable estimates for property tax, insurance, and HOA
- Field for an additional monthly payment and an amortization tab
- Bankrate notes PMI generally costs 0.46% to 1.50% of the loan each year
Best suited for
Buyers who are close to applying and want to see payments at current advertised rates for their credit score and ZIP code. It is less suited to early budgeting, when a rate guess is good enough.
4. NerdWallet Mortgage Calculator, best for a clean breakdown with PMI built in
Free
NerdWallet’s mortgage calculator has the clearest payment breakdown of the marketplace sites. You can enter property tax and homeowners insurance as annual dollar amounts or percentages, add monthly HOA dues, and include PMI, which appears automatically when your down payment is under 20%.
Its example shows why the extras matter: a $240,000, 30-year loan at 6.91% has a $1,582 principal and interest payment, but property tax of $375 and insurance of $160 bring the monthly total to $2,117. The amortization schedule then shows monthly principal, interest, and remaining balance.
Like Bankrate, NerdWallet places rate comparisons next to the result, showing how your rate compares with its best advertised rate and the national average. It does not offer the extra-payment depth of Calculator.net.
Key numbers
- Inputs: property tax and insurance (annual, $ or %), monthly HOA, and PMI
- PMI field appears automatically when the down payment is under 20%
- Amortization schedule with monthly principal, interest, and remaining balance
- Example result: $2,117/month at 6.91% on a $240,000, 30-year loan, including $375 tax and $160 insurance
- Compares your rate with NerdWallet’s best rate and the national average
Best suited for
Buyers putting down less than 20% who want PMI included without looking up a rate. It is a strong default for a quick, realistic monthly payment.
5. CFPB Explore Interest Rates, best for seeing how credit score and down payment change your rate
Free (U.S. government)
The Consumer Financial Protection Bureau’s Explore Interest Rates tool is not a payment calculator in the usual sense. It answers a question the others do not: how much do your credit score, down payment, loan term, and loan type change the rate you are likely to be offered, and what does that difference cost?
Each scenario shows a range of rates and the total interest paid in the first five years and over the full term, along with the dollar savings from a higher score, bigger down payment, shorter term, or an FHA or VA loan. The rate data comes from Curinos, which collects it directly from large banks, regional banks, and credit unions. Check the page for the date of the rate data, because it is not refreshed daily.
As a government tool, it carries no lender advertising and does not ask for contact details. Pair it with a payment calculator: use the CFPB tool to pick a realistic rate, then plug that rate into an affordability or payment calculator.
Key numbers
- Run by the Consumer Financial Protection Bureau, a U.S. federal agency
- Compares scenarios by credit score, down payment, loan term, and loan type (conventional, FHA, VA)
- Shows a rate range plus interest paid in the first 5 years and over the full term
- Rate data comes from Curinos, collected from banks and credit unions
- No advertising or lead forms
Best suited for
Buyers deciding whether to raise their credit score, save a larger down payment, or choose an FHA or VA loan before applying. It is not a substitute for a full payment calculator.

Frequently Asked Questions
What is the most accurate mortgage calculator?
Every calculator uses the same amortization formula, so accuracy depends on your inputs. Calculator.net and NerdWallet include taxes, insurance, HOA, and PMI, which makes the monthly total more realistic.
How much house can I afford?
Many lenders cap housing costs at about 28% of gross monthly income and total debts at 36%. An affordability calculator applies those limits to your income, debts, down payment, and rate.
What should I include in a mortgage calculator?
Home price, down payment, rate, and term, plus property tax, homeowners insurance, HOA dues, and PMI if you put down less than 20%. Leaving those out understates the payment.
How do extra payments affect my mortgage?
Extra payments reduce the balance immediately, so later interest is charged on less. On a $250,000 loan at 6.5%, $200 extra a month saves about $97,618 and 95 months.
What is the 28/36 rule?
Housing costs should be no more than 28% of gross monthly income, and all debt payments together no more than 36%. FHA loans often allow 31% and 43%.
Is a mortgage calculator result a pre-approval?
No. It is an estimate from the numbers you enter. A lender verifies income, credit, and assets before issuing a pre-approval or a Loan Estimate.
How does my credit score change my mortgage payment?
A higher score usually earns a lower rate, which lowers the payment and total interest. The CFPB’s Explore Interest Rates tool shows the rate range and interest cost for different score bands.
