What is PMI Calculator?
▾
Imagine you've found your dream home—the one with the perfect kitchen and the cozy backyard. You're ready to make an offer, but there's a catch: you don't have a 20% down payment saved up. Don't worry, most of us don't! This is where Private Mortgage Insurance, or PMI, comes into play. It's a special insurance policy that conventional lenders require when you put down less than 20% on a home loan. It protects the lender in case you can't make your payments, making them comfortable enough to approve your loan anyway. Our PMI Calculator is designed to take the mystery out of this monthly fee. Instead of guessing how much extra you'll owe each month, this tool gives you a clear, realistic estimate based on your home's price, your down payment, and your credit score. Think of it as your financial crystal ball, helping you see the true cost of homeownership before you sign on the dotted line. Understanding your PMI helps you budget smarter. It can show you whether it makes sense to save up a bit more down payment to lower your monthly rate, or if paying PMI is a worthwhile trade-off to get into your home sooner. By calculating this ahead of time, you can negotiate with lenders with confidence and avoid any unwelcome surprises when your first mortgage bill arrives.

Annual PMI Payment = Loan Amount × Annual PMI Rate
Monthly PMI Payment = (Loan Amount × Annual PMI Rate) ÷ 12
To find your loan amount, subtract your down payment from the home's purchase price. The PMI rate is a percentage (usually between 0.2% and 2.0%) determined by your lender based on your credit score and loan-to-value (LTV) ratio.Variable Legend

Worked Examples
▾
With a home purchase price of $300,000 and a 5% down payment ($15,000), the loan amount is $285,000. For a buyer with an excellent credit score, the estimated annual PMI rate is 0.5%. Multiplying the loan amount of $285,000 by 0.5% yields an annual PMI cost of $1,425. Dividing this by 12 months results in a monthly PMI payment of $118.75.
This scenario features a $400,000 home purchase with a 10% down payment ($40,000), leaving a loan amount of $360,000. Because the buyer has a fair credit score, the estimated PMI rate is slightly higher at 0.85%. The annual PMI cost is calculated as $360,000 multiplied by 0.85%, which equals $3,060, or $255.00 per month.
For a home purchased at $250,000 with a minimal 3% down payment ($7,500), the loan amount is $242,500. With a good credit score, the PMI rate is estimated at 0.75%. This results in an annual PMI payment of $1,818.75, which translates to a monthly payment of $151.56 added to the mortgage.
In this scenario, a buyer purchases a $500,000 home and puts down 15% ($75,000), leaving a loan amount of $425,000. Because they have a top-tier credit score and are very close to the 20% down payment threshold, they qualify for a low PMI rate of 0.3%. This results in an annual cost of $1,275, or just $106.25 per month.

Special Cases
▾
FHA Loans vs. Conventional Loans
FHA loans do not use conventional PMI; instead, they require a Mortgage Insurance Premium (MIP). Unlike conventional PMI, which drops off when you reach 20% equity, FHA MIP usually stays for the entire life of the loan if you put down less than 10% at purchase.
Rapid Home Value Appreciation
If your local housing market booms and your home's value shoots up, you might reach 20% equity much faster than expected. In this case, you can pay for a new appraisal to prove your loan-to-value is below 80% and request to cancel your monthly PMI early.
Lender-Paid Mortgage Insurance (LPMI)
Some lenders offer 'no PMI' loans, but there is a catch. The lender pays the PMI upfront for you in exchange for charging you a slightly higher interest rate. Calculate carefully to see if a higher interest rate over 30 years costs more than paying monthly PMI for just a few years.

| Credit Score Range | 5% Down Payment (95% LTV) | 10% Down Payment (90% LTV) | 15% Down Payment (85% LTV) |
|---|---|---|---|
| 760+ (Excellent) | 0.38% - 0.48% | 0.28% - 0.35% | 0.18% - 0.25% |
| 700 - 759 (Good) | 0.65% - 0.80% | 0.48% - 0.60% | 0.32% - 0.40% |
| 620 - 699 (Fair) | 1.10% - 1.50% | 0.85% - 1.10% | 0.55% - 0.75% |
Frequently Asked Questions
▾
How is private mortgage insurance (PMI) calculated?
PMI typically costs 0.2%-2.0% of the original loan amount per year, depending on: loan-to-value (LTV) ratio (higher LTV = higher PMI), credit score (below 680 pays significantly more), loan type (fixed vs adjustable), and coverage level (standard is 25-35% coverage). Example: $300,000 loan at 0.5% PMI rate = $1,500/year = $125/month. PMI rate ranges: 95% LTV with 760+ credit score ≈ 0.3%, 95% LTV with 680 credit score ≈ 0.8%, 90% LTV with 760+ ≈ 0.2%, 90% LTV with 680 ≈ 0.5%. Lender-paid PMI (LPMI) is built into the interest rate (typically 0.25-0.5% higher rate) instead of a separate monthly charge — calculate which costs more over your expected ownership period.
How do I get rid of PMI?
Automatic termination: under the Homeowners Protection Act, lenders must automatically cancel PMI when your loan balance reaches 78% of the original property value (based on the original purchase price, not current market value). You don't need to ask. Borrower-requested cancellation: you can request PMI removal when you reach 80% LTV. Requires: written request, good payment history (no late payments in 12+ months), and sometimes a new appraisal showing no decline in property value. Refinancing: if your home has appreciated significantly, refinancing at a lower LTV eliminates PMI. If you bought at $300,000 with 5% down and the home is now worth $375,000, your LTV based on current value could be below 80%. FHA loans are different: MIP (mortgage insurance premium) on FHA loans made after June 2013 with less than 10% down is required for the LIFE of the loan — the only way to remove it is to refinance into a conventional loan.
What is Private Mortgage Insurance (PMI) and why is it necessary?
Private Mortgage Insurance (PMI) is a type of insurance policy that protects the mortgage lender, not the borrower, in case the borrower defaults on their loan. It is typically required on conventional loans when a homebuyer makes a down payment of less than 20% of the home's purchase price. Lenders require PMI to mitigate the increased risk associated with borrowers who have less equity in their homes, as these loans historically have a higher default rate.
What factors influence the cost of PMI?
The cost of PMI is primarily influenced by your loan-to-value (LTV) ratio, credit score, debt-to-income (DTI) ratio, and the loan term. A higher LTV (e.g., a 95% LTV with only 5% down) generally results in a higher PMI premium, while a lower LTV (e.g., 85% LTV with 15% down) typically yields a lower premium. Borrowers with excellent credit scores (e.g., 760+) can often secure lower PMI rates compared to those with lower scores (e.g., 680). For instance, a borrower with a 740 credit score and 10% down might pay 0.5% of the loan amount annually, whereas a 680 credit score borrower with the same down payment might pay 0.8%.
Are there alternatives to PMI for borrowers with less than 20% down payment?
Yes, several alternatives can help borrowers avoid traditional PMI, even with a smaller down payment. One common option is a "piggyback" loan, often structured as an 80/10/10 loan, where 80% is the primary mortgage, 10% is a second mortgage (often a HELOC), and 10% is the down payment. Another alternative is Lender-Paid Mortgage Insurance (LPMI), where the lender pays the PMI premium in exchange for a slightly higher interest rate on the primary mortgage. Additionally, some lenders offer specific loan programs that do not require PMI for lower down payments, though these may come with other fees or higher interest rates.
Common Mistakes to Avoid
▾
- !Confusing PMI with homeowners insurance, which actually protects your house from physical damage
- !Assuming PMI is a permanent fee that you have to pay for the entire life of a conventional loan
- !Forgetting that your credit score affects your PMI rate just as much as your down payment size does
Pro Tip
Keep a close eye on your home's value! If home prices in your neighborhood are rising, you can request a new appraisal to cancel your PMI early, saving you hundreds of dollars a month without paying an extra dime toward your principal balance.
Did you know?
Did you know that PMI was actually created in 1957 by a self-made lawyer named Max Karl? He realized everyday people couldn't buy homes because saving a 20% down payment took too long, so he founded the first private mortgage insurance company to bridge the gap and help families buy homes sooner!
