Monthly payment by lender
This tool is useful for a wide range of situations. First-time buyers can figure out what they can realistically afford before house hunting. Homeowners considering a refinance can check whether a lower rate actually saves money once closing costs are factored in. Buyers weighing a 15-year loan against a 30-year loan can see the trade-off between a higher monthly payment and long-term interest savings. Anyone shopping multiple lenders can line up their offers side by side and see which one is genuinely the better deal, rather than relying on a single advertised rate.
Using the calculator is straightforward. Start by entering your home price and down payment, then add your expected interest rate and loan term. From there, you can layer in property tax, homeowners insurance, HOA dues, and private mortgage insurance (PMI) to get a full picture of your monthly payment, not just the principal and interest portion. Each section of the tool updates in real time, so you can adjust one variable — say, a larger down payment or a shorter term — and immediately see how it changes your monthly cost and total interest paid.
Comparing mortgage options matters because even small differences in rate or fees compound significantly over a 15- or 30-year term. A quarter-point difference in interest rate, or a few thousand dollars in closing costs, can add up to tens of thousands of dollars over the life of a loan. Reviewing these numbers side by side, rather than relying on a single lender’s pitch, puts you in a stronger position to negotiate and to choose the loan structure that actually fits your finances and how long you plan to stay in the home.
How to Use This Calculator
Follow these steps to get an accurate picture of your mortgage costs:
- Enter your home price and down payment. You can enter the down payment as a dollar amount or a percentage — the calculator keeps both in sync automatically.
- Add your interest rate and loan term. If you have a rate quote from a lender, use it. If not, use a current market rate as a starting estimate.
- Fill in property tax, insurance, HOA, and PMI. These “escrow” costs are often left out of quick estimates but make up a real part of your monthly payment.
- Review your results. Check your total monthly payment, the principal-and-interest split, total interest over the life of the loan, and your estimated payoff date.
- Run a comparison. Switch to the rate comparison, fixed vs. ARM, loan term, or lender comparison tools to test different scenarios against each other.
- Adjust and repeat. Try a larger down payment, a shorter term, or an extra monthly payment to see how each choice affects your total interest and payoff timeline.
- Save or share your results. Use the print, copy, or share options to keep a record of the scenario you’re considering, or to send it to a lender or partner for review.

Why Compare Mortgage Options?
Mortgage offers are rarely as simple as “rate A” versus “rate B.” Two loans with the same interest rate can have very different total costs once points, lender fees, and loan terms are factored in. Comparing your options before signing helps you avoid a few common, expensive mistakes:
- Overpaying because of a low rate with high fees. A slightly lower rate paired with several thousand dollars in points and fees can cost more overall than a higher rate with a lower fee structure — this is exactly what APR is designed to reveal.
- Choosing the wrong loan term for your situation. A 30-year loan lowers your monthly payment, while a 15-year loan builds equity faster and saves a substantial amount in interest. The right choice depends on your budget and how long you plan to stay in the home.
- Underestimating the real monthly payment. Property tax, insurance, HOA dues, and PMI can add hundreds of dollars to your monthly cost beyond principal and interest.
- Missing a better refinance opportunity. Rates and your financial situation change over time; comparing your current loan against current market rates can reveal savings you didn’t know were available.
- Assuming an ARM’s low intro rate lasts. Adjustable rate mortgages can look attractive at first glance, but comparing the intro rate against the post-adjustment rate shows the real long-term cost.
Taking the time to compare these factors side by side, using consistent numbers, gives you a clearer negotiating position with lenders and a more realistic budget for homeownership.
Tips to Save Money on Your Mortgage
- Shop multiple lenders. Rates and fees vary between lenders even on the same day, so getting at least three quotes typically uncovers meaningful savings.
- Compare APR, not just the rate. APR includes fees and points, giving a more accurate picture of the loan’s true cost over time.
- Increase your down payment when possible. A larger down payment reduces your loan amount, can help you avoid PMI, and often qualifies you for a better rate.
- Consider a shorter loan term. If the higher monthly payment fits your budget, a 15-year loan can save tens of thousands of dollars in interest compared to a 30-year loan.
- Make extra principal payments. Even a modest extra monthly payment can shorten your loan term by years and meaningfully cut total interest paid.
- Improve your credit before applying. A higher credit score generally qualifies you for a lower interest rate, which compounds into significant savings over the loan term.
- Watch closing costs when refinancing. A lower rate only helps if the monthly savings outweigh the upfront closing costs within a reasonable break-even period.
- Reassess PMI once you reach 20% equity. Once your loan-to-value ratio drops below 80%, you may be able to request PMI removal and lower your monthly payment.
Frequently Asked Questions
What does the Mortgage Comparison Tools calculator actually calculate?
It calculates your estimated monthly mortgage payment, including principal, interest, property tax, insurance, HOA dues, and PMI, and lets you compare that payment against different rates, loan terms, down payments, and lenders so you can see the total cost of each option side by side.
Is this calculator accurate enough to use for a real mortgage decision?
The results are estimates based on the figures you enter and standard mortgage math. They’re accurate for comparison purposes and planning, but your actual loan terms, fees, and APR will be confirmed by a licensed lender during underwriting.
What’s the difference between interest rate and APR?
The interest rate is the cost of borrowing the principal, while APR (annual percentage rate) includes the interest rate plus most lender fees and points spread over the loan term. APR generally gives a more complete picture of a loan’s true cost.
Should I choose a 15-year or 30-year mortgage?
A 15-year mortgage typically has a lower interest rate and saves significantly on total interest, but comes with a higher monthly payment. A 30-year mortgage offers a lower, more manageable monthly payment but costs more in interest over time. The Loan Term Comparison tool above can show you the exact trade-off using your own numbers.
How much down payment do I need to avoid PMI?
Most conventional lenders require private mortgage insurance (PMI) if your down payment is less than 20% of the home price. Once your loan-to-value ratio reaches 80%, you can typically request that PMI be removed.
When does refinancing actually make sense?
Refinancing generally makes sense when the new interest rate is low enough that your monthly savings pay back the closing costs within a reasonable time frame, often two to four years, and you plan to stay in the home longer than that break-even period.
What is an adjustable-rate mortgage (ARM), and is it risky?
An ARM offers a lower fixed rate for an initial period, typically 5, 7, or 10 years, before adjusting based on market rates. It can save money short-term, but carries the risk of higher payments after the adjustment period, which is why comparing it against a fixed-rate loan’s total cost is worthwhile before choosing one.
How do extra monthly payments affect my mortgage?
Extra payments applied directly to principal reduce the balance your interest is calculated on, which shortens your loan term and reduces total interest paid, sometimes by years and tens of thousands of dollars, depending on the amount and how early you start.
What income do I need to afford a given home price?
Lenders commonly use debt-to-income guidelines, such as keeping housing costs under about 28% of gross monthly income and total debt under about 36%. The Affordability Calculator above uses these ratios along with your income, debts, and loan details to estimate a realistic price range.
Can I use this calculator for an investment property or refinance?
Yes. You can use the Mortgage Payment Calculator for a standard purchase, and the Refinance Calculator for evaluating an existing loan. Keep in mind that investment properties often carry different rates, down payment requirements, and insurance costs than a primary residence, so adjust your inputs accordingly.
Making a More Informed Mortgage Decision
A mortgage is one of the largest financial commitments most people make, and small differences in rate, term, or fees can add up to significant money over time. The Mortgage Comparison Tools calculator is designed to take the guesswork out of that decision by putting real numbers in front of you — monthly payments, total interest, payoff timelines, and side-by-side lender comparisons — all in one place, instead of scattered across separate spreadsheets or lender quotes. Whether you’re buying your first home, comparing refinance offers, or deciding between a 15-year and 30-year term, running your own numbers before committing gives you a clearer, more confident starting point for conversations with lenders, and a way to sanity-check any offer you’re given.
No calculator replaces the advice of a licensed loan officer or financial advisor, but walking into that conversation with a solid estimate of what you can afford and what different loan structures will actually cost puts you in a stronger position. Explore the full set of calculators to plan other parts of your homeownership budget, and revisit this page any time your rate, income, or home search changes.
