Use Bankrate if you want a payment tool whose published how-to starts with home price, down payment, credit-score range, and ZIP code, then lets you pick a suggested rate or type your own. Use NerdWallet if you want a how-to that starts with home price, down payment, interest rate, and term, then shows principal, interest, taxes, insurance, HOA, and PMI in a Loan Estimate window. Neither calculator is a lender quote, and neither how-to says the tool underwrites FHA, VA, or USDA rules.
The useful compare is the published form, not a leaderboard. Run the same home price, down payment, term, and a dated national average through both tools, then check the same inputs on HomeMortgageOnline. This page uses this site's latest market-update stamps as of September 10, 2026. The homepage hero still shows an older 6.66% stamp as of September 3, 2026. The Bankrate and NerdWallet field notes below come from each publisher's calculator how-to, retrieved 2026-09-15. They are not a live click-through of the widgets.
Which mortgage calculator should you use?
Bankrate's calculator how-to, retrieved 2026-09-15, is the better fit when you want the tool to propose a rate. It tells you to enter home price, down payment, credit-score range, and ZIP code, then choose a 10-, 15-, 20-, or 30-year term. It says you can use Bankrate's top offer, the national average, or a rate you already have.
NerdWallet's calculator how-to, retrieved 2026-09-15 at the URL that returned HTTP 200, is the better fit when you already have a rate in mind. The core fields it lists are home price, down payment, interest rate, and loan term. It says results land in a Loan Estimate window with monthly payment, total principal, total interest, total loan payments, and a payoff date.
HomeMortgageOnline's mortgage payment calculator also asks you to type the rate. Principal, interest, taxes, insurance, and HOA update in the browser. Nothing is sent to a server. This site does not lend and does not attach a marketplace quote to the result.
How do the calculator how-tos differ?
Bankrate's how-to adds two fields NerdWallet's how-to does not list on the first four steps: credit-score range and ZIP code. Bankrate says those inputs "help generate a more accurate rate estimate for your area and borrower profile." That is still an estimate. It is not a Loan Estimate from a lender and it is not a lock.
NerdWallet's how-to keeps the first four fields to home price, down payment, interest rate, and loan term, then says to open taxes, insurance, HOA, and PMI under Show Advanced Info. It says property tax and homeowners insurance are annual, and HOA and PMI are monthly. It says the PMI field appears only when the down payment is under 20 percent.
HomeMortgageOnline puts annual taxes, insurance, and HOA on the main form. PMI is not inside that calculator. Use the PMI calculator when the down payment is under 20 percent on a conventional loan. Closing costs are a separate closing cost calculator.
| Input or output named in the how-to | Bankrate how-to (2026-09-15) | NerdWallet how-to (2026-09-15) | HomeMortgageOnline |
|---|---|---|---|
| Home price and down payment | Yes | Yes | Yes |
| You type the interest rate | Optional (or use their top offer or national average) | Listed as a required field | Required |
| Credit-score band and ZIP | Listed | Not listed in the four-field how-to | No |
| Loan term choices | 10, 15, 20, or 30 years | Loan term (years) | Years field |
| Taxes, insurance, HOA | Rough estimates, then editable | Show Advanced Info (annual tax and insurance; monthly HOA) | On the main form (annual tax and insurance; monthly HOA) |
| PMI | Described when down payment is under 20% | Monthly field when down payment is under 20% | Separate PMI calculator |
| Amortization | Amortization tab; extra payment field named "Additional amount to monthly payment" | Amortization Schedule in the Loan Estimate window | Total interest over the loan; no extra-payment field |
| Rate-compare section on the same page | How-to includes a heading "Compare current mortgage rates for today" | How-to lists payment fields only | None. We do not lend. |

What rate should you type into either calculator?
Type a dated national average from this site, or a written rate from a lender, and label the as-of date. Do not mix a weekly survey from one week with a daily index from another week and call them the same number.
This site's latest market update, dated September 10, 2026, stamps Freddie Mac's Primary Mortgage Market Survey at 6.76% for the 30-year fixed and 6.09% for the 15-year fixed. The same note stamps Bankrate's daily national average that morning at 6.85% (6.92% APR) for 30-year fixed and 6.22% (6.32% APR) for 15-year fixed. Mortgage News Daily's daily index that day was 7.07% for 30-year fixed and 6.62% for 15-year fixed.
The homepage hero still shows 6.66% for 30-year fixed as of September 3, 2026. That is an older first-party stamp. The September 10 market update is the newer one, so the payment examples below use September 10.
Rate note: those figures are national averages for education only. They are not a personal quote, not a guaranteed APR, and not a rate lock. Your price depends on credit, down payment, loan type, points, fees, and the day a lender prices the file.
What does a like-for-like payment test look like?
Hold the house and the down payment still, then change only the rate or the term. On a $400,000 home with $80,000 down, the loan amount is $320,000. Principal-and-interest only, using this site's September 10, 2026 stamps:
- 30-year fixed at the 6.76% PMMS stamp: about $2,078 a month, and about $427,951 of interest if you keep the loan to term.
- 15-year fixed at the 6.09% PMMS stamp: about $2,716 a month, and about $168,867 of interest to term.
- The same 30-year loan at Bankrate's 6.85% daily stamp: about $2,097 a month.
- The same 30-year loan at Mortgage News Daily's 7.07% daily stamp: about $2,144 a month.
The 15-year payment is about $638 a month higher than the 6.76% 30-year case, and the scheduled interest is about $259,000 lower if you hold the loan to term. That is calendar math on a national average, not a reason to pick a term and not a quote.
Enter those same four inputs in Bankrate's mortgage calculator and NerdWallet's mortgage calculator, then repeat them in the HomeMortgageOnline payment calculator. If the principal-and-interest line differs, check whether taxes, insurance, PMI, or a suggested rate got mixed into the total.
How should you compare loan types in these calculators?
Compare loan types by changing down payment, term, mortgage insurance, and the rate you type. Do not treat a calculator result as a program approval. The CFPB's owning-a-home hub puts it this way: "Choosing the right home loan is just as important as choosing the right home."
A conventional loan on this site's loan types hub is the common path with at least 3% to 5% down and PMI when you put down less than 20%. FHA can use 3.5% down with qualifying credit, but it charges mortgage insurance premiums that do not behave like cancellable PMI. VA loans can use 0% down and no monthly PMI for eligible borrowers, with a funding fee unless the borrower is exempt. USDA loans can also use 0% down, subject to income and property-location limits. Jumbo loans sit above conforming limits and usually need more reserves.
Neither publisher's how-to says the calculator turns those program rules on automatically. Bankrate's how-to describes PMI for conventional loans under 20% down. NerdWallet's terminology list says FHA uses a mortgage insurance premium instead of PMI. If you are testing FHA, VA, or USDA, type the insurance or funding-fee effect yourself, or use this site's FHA loan guide, VA loan guide, and USDA eligibility page. HUD's Single Family Housing office is the program home for FHA and related single-family products.
Term is the other clean compare. Bankrate's how-to lists 10-, 15-, 20-, and 30-year terms. NerdWallet's how-to and HomeMortgageOnline take a year count. A 15-year run at 6.09% and a 30-year run at 6.76%, using the September 10 stamps above, show the payment-versus-interest trade without a lender pitch.
If you are still choosing a product family, the ARM versus fixed-rate guide covers index, margin, and caps. The affordability calculator solves a home-price range from income, debts, and a target DTI. The CFPB's owning-a-home tools walk from shopping to the Loan Estimate and Closing Disclosure.
Disclaimer: this compare page is for general education. It is not financial advice and not a commitment to lend. HomeMortgageOnline does not lock rates, issue Loan Estimates, or promise an APR. Calculator outputs are estimates. Offers vary by lender, credit, points, fees, loan type, and market conditions.
